prevent personal injury or damage to your vehicle:

•

Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the
vehicle.

•

Turn on the Hazard Warning Flashers.

•

Apply the parking brake firmly and shift an auto-
matic transmission into PARK; a manual transmis-
sion into REVERSE.

•

Block the wheel diagonally opposite the wheel to
be raised.

•

Never start or run the engine with the vehicle on a
jack.

•

Do not let anyone sit in the vehicle when it is on a
jack.

•

Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.

•

Only use the jack in the positions indicated and for
lifting this vehicle during a tire change.

•

5. Raise the vehicle by turning the jack screw clock-

wise. Raise the vehicle only until the tire just clears
the surface and enough clearance is obtained to
install the spare tire. Minimum tire lift provides
maximum stability.

WARNING!

Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to change the tire.

6. Remove the lug nuts and wheel.

7. Mount the spare tire on the axle.

8. Install the lug nuts with the cone-shaped end toward

the wheel. Lightly tighten the lug nuts clockwise.

WARNING!

To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.

9. Lower the vehicle by turning the jack screw to the

counterclockwise, and remove the jack.

10. Finish tightening the wheel bolts. Push down on

the wrench while at the end of the handle for
increased leverage. Tighten the wheel bolts in a
star pattern until each wheel bolt has been tight-
ened twice

page 342. If in doubt about the

correct tightness, have them checked with a torque
wrench by an authorized dealer or at a service
station.

11. After 25 miles (40 km), check the lug nut torque

with a torque wrench to ensure that all lug nuts are
properly seated against the wheel.

12. Remove the jack assembly and wheel blocks.

13. Secure the jack and tools in their proper locations.

14. Secure the damaged wheel/tire on the spare tire

carrier. Torque down lug nuts and locking lug nut.

15. Return the lock bolt to the lock position on the

camera cover by turning the lock clockwise using
the provided #40 torx head driver and ratchet.
Then, reinstall the camera cover by slipping it over
the camera/tire carrier until it snaps into place.

WARNING!

A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the
vehicle. Always stow the jack parts and the spare tire
in the places provided.

JUMP STARTING

If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in
another vehicle, or by using a portable battery booster
pack. Jump starting can be dangerous if done improp-
erly, so please follow the procedures in this section
carefully.

The vehicle requires its 12 Volt battery power to turn-on
the vehicle's high voltage battery. The high voltage bat-
tery is used to charge the 12 Volt battery, provide elec-
tric vehicle operation, and to start the vehicle's gas
engine. If the 12 Volt battery has been discharged, the

vehicle can be jump started using a set of jumper
cables and a battery in another vehicle or by using a
portable battery booster pack.

If the vehicle's high voltage battery has also been dis-
charged, it will need to be recharged to a minimum
operating State Of Charge (SOC) before the vehicle can
be started:

•

If the vehicle can be connected to a Level 1 or Level
2 charger where it is currently parked, the vehicle
will still require a jump start to allow the vehicle to
begin the battery charging process. Once the vehicle
charging has begun (indicated by the charge status
indicator on top of the vehicle's instrument panel),
the jumper cables can be removed from the vehicle
jump posts.

•

If the vehicle cannot be connected to a Level 1 or
Level 2 charger where it is currently parked, the
vehicle can be moved by connecting 12 Volt power
to the vehicle's jump posts and then shifting the
transmission from PARK (P) into NEUTRAL (N).
Power provided by the jumper cables will also allow
the Electric Park Brake to be released. Carefully
move the vehicle to a Level 1 or Level 2 charge loca-
tion. While the vehicle is being moved, the external
12 Volt power must remain connected to the vehicle
jump posts.

NOTE:

Be careful when moving the vehicle - ensure that con-
trol of the vehicle is maintained. Also, ensure that
vehicle is secured to prevent unintentional movement
during and after moving the vehicle. If the external

12 Volt power becomes disconnected from the vehicle
jump posts or there is an interruption of the 12 Volt
power while moving the vehicle, the vehicle's transmis-
sion may engage PARK. Do not allow the jumper cables
to come in contact with each other or to the vehicle,
this will result in a short.

When the vehicle is at the charging location, shift the
transmission back to PARK, apply the Electric Park
Brake, and start the high voltage battery charging. Once
the vehicle has been secured against unintentional
movement and high voltage battery charging has been
initiated, the jumper cables can be removed from the
vehicle jump posts.

WARNING!

Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.

CAUTION!

Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.

NOTE:

When using a portable battery booster pack, follow the
manufacturer's operating instructions and precautions.

PREPARATIONS FOR JUMP START

WARNING!

•

Only use the positive battery post on the main bat-
tery to jump start your vehicle. Serious injury or
death could result if you attempt to jump start
using the supplemental battery.

•

Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.

•

Never use a fast battery charger to start the
engine, as this could damage the electronic sys-
tems of your vehicle, particularly the ignition and
engine fuel supply control units.

•

If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery.

•

Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.

The battery in your vehicle is located in the right rear of
the engine compartment.

5/22/2023 9:02:29 AM

NOTE:

The positive (+) battery post is covered with a protective
cap. Lift up on the cap to gain access to the post.

See the following steps to prepare for jump starting:

1. Apply the parking brake, shift the automatic trans-

mission into PARK (P) (manual transmission in NEU-
TRAL) and turn the ignition OFF.

2. Turn off the heater, radio, and all electrical

accessories.

3. Pull upward and remove the protective cover over

the positive

(+)

battery post.

4. If using another vehicle to jump start the battery,

park the vehicle within the jumper cable’s reach,
apply the parking brake and make sure the ignition
is OFF.

WARNING!

•

Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.

•

Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by moving
fan blades.

•

Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadver-
tent electrical contact. You could be seriously
injured.

•

Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.

If your vehicle is equipped with a Stop/Start system, it
will be equipped with two batteries

5/22/2023 9:02:29 AM

4. Connect the opposite end of the negative

(-)

jumper

cable to a good engine ground. A “ground” is an
exposed metallic/unpainted part of the engine,
frame or chassis, such as an accessory bracket or
large bolt. The ground must be away from the bat-
tery and the fuel injection system.

WARNING!

Do not connect the jumper cable to the negative

(-)

post of the discharged battery. The resulting electrical
spark could cause the battery to explode and could
result in personal injury.

CAUTION!

Make sure at all times that unused ends of jumper
cables are not contacting each other or either vehicle
while making connections. Failure to follow these pro-
cedures could result in damage to the charging sys-
tem of the booster vehicle or the discharged vehicle.

5. Start the engine in the vehicle that has the booster

battery, let the engine idle a few minutes, and then
start the engine in the vehicle with the discharged
battery.

CAUTION!

Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle engine.

6. Once the engine is started, remove the jumper

cables in the reverse sequence.

Disconnecting The Jumper Cables

1. Disconnect the negative

(-)

end of the jumper cable

from the engine ground of the vehicle with the dis-
charged battery.

2. Disconnect the opposite end of the negative

(-)

jumper cable from the negative

(-)

post of the

booster battery.

3. Disconnect the positive

(+)

end of the jumper cable

from the positive

(+)

post of the booster battery.

4. Disconnect the opposite end of the positive

(+)

jumper cable from the positive

(+)

post of the dis-

charged vehicle.

5. Reinstall the protective cover over the positive

(+)

post of the discharged vehicle.

NOTE:

If frequent jump starting is required to start your vehicle
you should have the battery and charging system tested
at an authorized dealer.

CAUTION!

Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when
not in use (i.e., cellular devices, etc.). Eventually, if
plugged in long enough without engine operation, the
vehicle’s battery will discharge sufficiently to degrade
battery life and/or prevent the engine from starting.

IF YOUR ENGINE OVERHEATS

If the vehicle is overheating, it will need to be serviced
by an authorized dealer.

Potential signs of vehicle overheating:

•

Temperature gauge is at HOT (H)

•

Strong smell of coolant

•

White smoke coming from engine or exhaust

•

Coolant bottle coolant has bubbles present

WARNING!

You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do
not open the hood until the radiator has had time to
cool. Never try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.

If the temperature gauge is moving towards or close to
the HOT (H) position, you can reduce the potential for
overheating by taking the appropriate action.

•

On highways — slow down.

•

In city traffic — while stopped, place the transmis-
sion in NEUTRAL (N), but do not increase the engine
idle speed while preventing vehicle motion with the
brakes.

•

Turn the Air Conditioner (A/C) off. The A/C system
adds heat to the engine cooling system and turning
the A/C off can help remove this heat.

•

Turn the temperature control to maximum heat, and
the blower control to high. This allows the heater
core to act as a supplement to the radiator and aids
in removing heat from the engine cooling system.

CAUTION!

Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.

MANUAL PARK RELEASE

In order to move the vehicle in cases where the trans-
mission will not shift out of PARK (P) (such as a
depleted battery), a Manual Park Release is available.

WARNING!

Always secure your vehicle by fully applying the park-
ing brake before activating the Manual Park Release.
In addition, you should be seated in the driver’s seat
with your foot firmly on the brake pedal when activat-
ing the Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll away if it is
not secured by the parking brake, or by proper con-
nection to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to seri-
ous injury or death for those in or around the vehicle.

See the following steps to use the Manual Park
Release:

1. Firmly apply the parking brake.

2. Using a small screwdriver or similar tool, remove the

manual park release cover located in front of the
gear selector, to access the release tether strap.

3. Fish the tether strap up through the opening in the

console base.

4. Press and maintain firm pressure on the brake

pedal.

5. Pull the tether strap up until the release lever locks

into place in the vertical position. The vehicle is now
out of PARK (P) and can be moved. Release the
parking brake only when the vehicle is securely con-
nected to a tow vehicle.

3. Tuck the tether strap into the base of the console,

and reinstall the cover.

NOTE:

When the lever is locked in the release position the
access cover cannot be reinstalled.

FREEING A STUCK VEHICLE

If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around
the front wheels. For vehicles with automatic transmis-
sion, push and hold the lock button on the gear selec-
tor. Then, shift back and forth between DRIVE (D) and
REVERSE (R) (with automatic transmission) or SECOND
(2) gear and REVERSE (R) (with manual transmission),
while gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that will maintain
the rocking motion, without spinning the wheels or rac-
ing the engine.

NOTE:

•

For vehicles with automatic transmission: Shifts
between DRIVE (D) and REVERSE (R) can only be
achieved at wheel speeds of 5 mph (8 km/h) or
less. Whenever the transmission remains in NEU-
TRAL (N) for more than two seconds, you must press
the brake pedal to engage DRIVE (D) or REVERSE
(R).

•

Push the ESC OFF button to place the Electronic
Stability Control (ESC) system in “Partial OFF” mode,
before rocking the vehicle

page 225. Once the

vehicle has been freed, push the ESC OFF button
again to restore “ESC On” mode.

WARNING!

Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage,
or even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle's wheels faster than 30 mph (48 km/h) or for lon-
ger than 30 seconds continuously without stopping
when you are stuck and do not let anyone near a
spinning wheel, no matter what the speed.

CAUTION!

•

Racing the engine or spinning the wheels may lead
to transmission overheating and failure. Allow the
engine to idle with the transmission in NEUTRAL
for at least one minute after every five rocking-
motion cycles. This will minimize overheating and
reduce the risk of clutch or transmission failure
during prolonged efforts to free a stuck vehicle.

•

When “rocking” a stuck vehicle by shifting between
DRIVE/SECOND gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.

•

Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).

SERVICING AND MAINTENANCE

SCHEDULED SERVICING

Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.

Based on engine operation conditions, the oil change indi-
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer towing, and extremely hot or
cold ambient temperatures will influence when the
“Change Oil” or “Oil Change Required” message is dis-
played. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).

On vehicles equipped with an instrument cluster display,
“Oil Change Required” will be displayed and a single
chime will sound, indicating that an oil change is
necessary.

On non-instrument cluster display equipped vehicles,
“Change Oil” will flash in the instrument cluster odom-
eter and a single chime will sound, indicating that an oil
change is necessary.

NOTE:

PHEV (If Equipped):

Even though the vehicle may not

have been driven, both the fuel in the tank and oil in
the engine will still degrade over time. Additionally,
there will be a notification to the driver if the engine is
being run to maintain the oil and fuel systems.

An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If
a scheduled oil change is performed by someone other
than an authorized dealer, the message can be reset by
referring to the steps described under Instrument Clus-
ter Display

page 124.

NOTE:

Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or
350 hours of engine run time, whichever comes first.
The 350 hours of engine run or idle time is generally
only a concern for fleet customers.

Once A Month Or Before A Long Trip:

•

Check the engine oil level.

•

Check the windshield washer fluid level.

•

Check the tire inflation pressures and look for
unusual wear or damage, rotate at the first sign of
irregular wear.

•

Check the fluid levels of the coolant reservoir, brake
master cylinder, and power steering, and fill as
needed.

•

Check the function of all interior and exterior lights.

MAINTENANCE PLAN

Refer to the maintenance plan for the required maintenance intervals.

At Every Oil Change Interval As Indicated By Oil Change Indicator System

•

CHECKING OIL LEVEL

To ensure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time
to check the engine oil level is about five minutes after
a fully warmed up engine is shut off.

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.

There are four possible dipstick types:

•

Crosshatched zone.

•

Crosshatched zone marked SAFE.

•

Crosshatched zone marked with MIN at the low end
of the range and MAX at the high end of the range.

•

Crosshatched zone marked with dimples at the MIN
and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch
markings on the dipstick.

NOTE:

Use care when filling under hood fluids such as engine
oil, washer fluid, antifreeze, etc., to minimize spillage
onto the top of the engine. Any excess fluid that is
spilled onto the top of the engine should be removed
using compressed air or an absorbent cloth.

Adding 1 qt (1 L) of oil when the reading is at the low
end of the dipstick range will raise the oil level to the
high end of the range marking.

CAUTION!

Overfilling or underfilling the crankcase will cause aera-
tion or loss of oil pressure. This could damage your
engine.

ADDING WASHER FLUID

The fluid reservoir for the windshield washers and the
rear window washer (if equipped) is shared. The fluid
reservoir is located in the engine compartment. Be sure
to check the fluid level at regular intervals. Fill the res-
ervoir with windshield washer solvent only (not radiator
antifreeze). When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades; this will help blade
performance.

To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets
or exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.

NOTE:

WARNING!

Commercial windshield washer solvents are flam-
mable. They could ignite and burn you. Care must be
exercised when filling or working around the washer
solution.

MAINTENANCE-FREE BATTERY

Your vehicle is equipped with a maintenance-free bat-
tery. You will never have to add water, and periodic
maintenance is not required.

WARNING!

•

Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area immedi-
ately with large amounts of water

page 274.

•

Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.

•

Vehicles with the Stop/Start system will be
equipped with two batteries. Both the main and
the supplemental batteries must be disconnected
to completely de-energize the 12 Volt electrical
system.

•

Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.

CAUTION!

•

It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked posi-
tive (+) and negative (-) and are identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.

•

If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage.

•

Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple-
mental batteries must be disconnected to completely
de-energize the 12 Volt electrical system.

•

If the negative battery cables are not isolated prop-
erly it can cause a potential power spike or surge
in the system, resulting in damage to essential
electrical components.

PRESSURE WASHING

Cleaning the engine compartment with a high pressure
washer is not recommended.

CAUTION!

Precautions have been taken to safeguard all parts
and connections however, the pressures generated
by these machines is such that complete protection
against water ingress cannot be guaranteed.

VEHICLE MAINTENANCE

An authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.

NOTE:

Intentional tampering with emissions control systems
may void your warranty and could result in civil penal-
ties being assessed against you.

WARNING!

You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.

ENGINE OIL

NOTE:

Hemi engines (6.4L) at times can tick right after startup
and then quiet down after approximately 30 seconds.
This is normal and will not harm the engine. This char-
acteristic can be caused by short drive cycles. For
example, if the vehicle is started then shut off after
driving a short distance. Upon restarting, you may expe-
rience a ticking sound.

Other causes could be if the vehicle is unused for an
extended period of time, incorrect oil, extended oil
changes or extended idling. If the engine continues to
tick or if the Malfunction Indicator Light (MIL) comes on,
see the nearest authorized dealer.

American Petroleum Institute (API)

BODY LUBRICATION

Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as Mopar® Spray White Lube to ensure quiet,
easy operation and to protect against rust and wear.
Prior to the application of any lubricant, the parts con-
cerned should be wiped clean to remove dust and grit;
after lubricating excess oil and grease should be
removed. Particular attention should also be given to
hood latching components to ensure proper function.
When performing other underhood services, the hood
latch release mechanism, and safety catch should be
cleaned and lubricated.

Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and
a mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.

Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always
use washer fluid when using the wipers to remove salt
or dirt from a dry windshield.

Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact
with petroleum products such as engine oil, gasoline,
etc.

NOTE:

Life expectancy of wiper blades varies depending on
geographical area and frequency of use. Poor perfor-
mance of blades may be present with chattering,
marks, water lines or wet spots. If any of these condi-
tions are present, clean the wiper blades or replace as
necessary.

The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the
following points:

•

Wear or uneven edges

•

Foreign material

•

Hardening or cracking

•

Deformation or fatigue

EXHAUST SYSTEM

The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine
exhaust system.

If you notice a change in the sound of the exhaust sys-
tem; or if exhaust fumes can be detected inside the
vehicle; or when the underside or rear of the vehicle is
damaged; have an authorized technician inspect the
complete exhaust system and adjacent body areas for

broken, damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit exhaust
fumes to seep into the passenger compartment. In
addition, have the exhaust system inspected each time
the vehicle is raised for lubrication or oil changes.
Replace as required.

WARNING!

•

Exhaust gases can injure or kill. They contain car-
bon monoxide (CO), which is colorless and odor-
less. Breathing it can make you unconscious and
can eventually poison you

page 265.

•

A hot exhaust system can start a fire if you park
over materials that can burn. Such materials might
be grass or leaves coming into contact with your
exhaust system. Do not park or operate your
vehicle in areas where your exhaust system can
contact anything that can burn.

CAUTION!

•

The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will destroy
the effectiveness of the catalyst as an emissions
control device and may seriously reduce engine
performance and cause serious damage to the
engine.

•

Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Con-
tinued operation of your vehicle with a severe

(Continued)

CAUTION!

malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is
important to keep the engine properly tuned to ensure
proper catalyst operation and prevent possible catalyst
damage.

NOTE:

Intentional tampering with emissions control systems
can result in civil penalties being assessed against you.

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool. Ser-
vice, including a tune-up to manufacturer's specifica-
tions, should be obtained immediately.

To minimize the possibility of catalytic converter
damage:

•

Do not interrupt the ignition when the transmission
is in gear and the vehicle is in motion.

•

Do not try to start the vehicle by pushing or towing
the vehicle.

•

Do not idle the engine with any ignition components
disconnected or removed, such as during diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.

COOLING SYSTEM

WARNING!

•

You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the
hood, do not open the hood until the radiator has
had time to cool. Never open a cooling system
pressure cap when the radiator or coolant bottle is
hot.

•

Keep hands, tools, clothing, and jewelry away from
the radiator cooling fan when the hood is raised.
The fan starts automatically and may start at any
time, whether the engine is running or not.

•

When working near the radiator cooling fan, discon-
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.

Coolant Checks

Check the engine, battery (if equipped), intercooler
(if equipped), and Motor Generator Unit (MGU)
(if equipped) coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine, battery (if equipped), inter-
cooler (if equipped), and MGU (if equipped) coolant is
dirty or rusty in appearance, the system should be
drained, flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser (if equipped) or
radiator for any accumulation of bugs, leaves, etc.
If dirty, clean by gently spraying water from a garden
hose vertically down the face of the A/C condenser
(if equipped) or the back of the radiator core.

Check the engine, battery (if equipped), intercooler
(if equipped), and MGU (if equipped) cooling system
hoses for brittle rubber, cracking, tears, cuts, and tight-
ness of the connection at the coolant recovery bottle
and radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.

Cooling System — Drain, Flush And Refill

NOTE:

Some vehicles require special tools to add coolant prop-
erly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed
to be added to the system please contact an authorized
dealer.

If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (conforming to MS.90032).

For the proper maintenance intervals, see

page 282.

Electric/Battery Coolant System — PHEV

(If Equipped)

These coolant systems must be serviced by an autho-
rized dealer. If the coolant level is below what is speci-
fied on the reservoir, contact an authorized dealer for
service.

These systems require the use of high purity water,
such as deionized, or distilled water, when mixing the
water and coolant (antifreeze) solution. The use of
lower quality water will reduce the amount of corrosion
protection in the cooling systems. If the coolant level of
the battery coolant system is low, the Hybrid Electric
Vehicle System Service Light will be illuminated on the
instrument cluster.

Selection Of Coolant

For further information

page 346.

NOTE:

•

Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) engine
coolant, may result in engine damage and may
decrease corrosion protection. OAT engine coolant is
different and should not be mixed with Hybrid
Organic Additive Technology (HOAT) engine coolant
or any “globally compatible” coolant. If a non-OAT
engine coolant is introduced into the cooling system
in an emergency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT coolant
(conforming to MS.90032), by an authorized dealer
as soon as possible.

•

Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or anti-rust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.

•

This vehicle has not been designed for use with pro-
pylene glycol-based engine coolant. Use of propyl-
ene glycol-based engine coolant is not
recommended.

•

Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any cool-
ant is needed to be added to the system please con-
tact an authorized dealer.

Adding Coolant

Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
coolant (antifreeze) can be used up to 10 years or
150,000 miles (240,000 km) before replacement. To
prevent reducing this extended maintenance period, it
is important to use the same engine coolant (OAT cool-
ant conforming to MS.90032) throughout the life of
your vehicle.

Please review these recommendations for using
Organic Additive Technology (OAT) engine coolant that
meets the requirements of the manufacturer Material
Standard MS.90032. When adding engine coolant
(antifreeze):

•

We recommend using Mopar® Antifreeze/Coolant
10 Year/150,000 Mile (240,000 km) Formula OAT
(Organic Additive Technology) that meets the
requirements of the manufacturer Material Stan-
dard MS.90032.

•

Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of the manufacturer
Material Standard MS.90032 and distilled water.
Use higher concentrations (not to exceed 70%) if
temperatures below −34°F (−37°C) are anticipated.
Please contact an authorized dealer for assistance.

•

Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
solution. The use of lower quality water will reduce
the amount of corrosion protection in the engine
cooling system.

NOTE:

•

It is the owner's responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the
vehicle is operated.

•

Use care when filling under hood fluids such as
engine oil, washer fluid, antifreeze, etc., to minimize
spillage onto the top of the engine. Any excess fluid
that is spilled onto the top of the engine should be
removed using compressed air or an absorbent
cloth.

•

Mixing engine coolant types is not recommended
and can result in cooling system damage. If HOAT
and OAT coolant are mixed in an emergency, have
an authorized dealer drain, flush, and refill with OAT
coolant (conforming to MS.90032) as soon as
possible.

Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that engine
coolant will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped.

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing
surfaces.

WARNING!

•

Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is
overheated. Do not loosen or remove the cap to
cool an overheated engine. Heat causes pressure
to build up in the cooling system. To prevent scald-
ing or injury, do not remove the pressure cap while
the system is hot or under pressure.

•

Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or engine
damage may result.

Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) OAT or
HOAT, is a regulated substance requiring proper dis-
posal. Check with your local authorities to determine
the disposal rules for your community. To prevent inges-
tion by animals or children, do not store ethylene glycol-
based coolant in open containers or allow it to remain
in puddles on the ground, clean up any ground spills
immediately. If ingested, seek emergency assistance
immediately.

Coolant Level

The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.

The radiator normally remains completely full, so there
is no need to remove the radiator/coolant pressure cap
unless checking for engine coolant freeze point or
