seated against the wheel.

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 improperly, so please
follow the procedures in this section carefully.

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.

IN CASE OF EMERGENCY

421

Preparations For Jump Start

The battery in your vehicle is located under the passenger’s
front seat. There are remote terminals located under the
hood to assist in jump starting.

WARNING!

• Take care to avoid the radiator cooling fan whenever

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 inadvertent
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.

NOTE:

Be sure that the disconnected cable ends do not

touch each other, or either vehicle, until properly con-
nected for jump starting.

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

sion into PARK and turn the ignition OFF.

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

accessories.

3. Remove the protective cover over the remote positive

(+)

battery post. Pull upward on the cover to remove it.

Jump Starting Locations

(+) — Remote Positive Post (Covered With Protective Cap)
(-) — Remote Negative Post

422

IN CASE OF EMERGENCY

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

the vehicle within the jumper cables 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.

Jump Starting Procedure

WARNING!

Failure to follow this jump starting procedure could
result in personal injury or property damage due to
battery explosion.

CAUTION!

Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.

NOTE:

Make sure at all times that unused ends of jumper

cables are not contacting each other or either vehicle while
making connections.

Connecting The Jumper Cables

1. Connect the positive (+) end of the jumper cable to the

remote positive (+) post of the discharged vehicle.

2. Connect the opposite end of the positive (+) jumper

cable to the positive (+) post of the booster battery.

3. Connect the negative end (-) of the jumper cable to the

negative (-) post of the booster battery.

4. Connect the opposite end of the negative (-) jumper

cable to the remote negative (-) post of the vehicle with
the discharged battery.

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. Only use the specific ground point, do
not use any other exposed metal parts.

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.

IN CASE OF EMERGENCY

423

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 remote negative (-) post of the discharged vehicle.

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 remote positive (+) post of the discharged
vehicle.

5. Reinstall the protective cover over the remote positive

(+)

post of the discharged vehicle.

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.

REFUELING IN EMERGENCY

The funnel for the Cap-Less Fuel System is located in the
spare tire storage area. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.

For more information on the Cap-Less Fuel System refer to
“Refueling The Vehicle” in “Starting And Operating”.

424

IN CASE OF EMERGENCY

IF YOUR ENGINE OVERHEATS

In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in

NEUTRAL, but do not increase the engine idle speed
while preventing vehicle motion with the brakes.

NOTE:

There are steps that you can take to slow down an

impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C

system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.

• You can also turn the temperature control to maximum

heat, the mode control to floor 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.

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.

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.

425

MANUAL PARK RELEASE

WARNING!

Always secure your vehicle by fully applying the
parking brake before activating the Manual Park Re-
lease. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating 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 connection to a tow vehicle. Activating the
Manual Park Release on an unsecured vehicle could
lead to serious injury or death for those in or around
the vehicle.

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

Follow these steps to use the Manual Park Release:

1. Firmly apply the parking brake.

2. Open the center console and locate the Manual Park

Release cover, remove it by snapping the cover away
from the console hinges.

3. Press and maintain firm pressure on the brake pedal.

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. Push and hold the lock button on the gear selector.
Then, shift back and forth between DRIVE and REVERSE
while gently pressing the accelerator.

428

IN CASE OF EMERGENCY

NOTE:

Shifts between DRIVE and REVERSE can only be

achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for more
than two seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal pressure that will
maintain the rocking motion without spinning the wheels
or racing the engine.
NOTE:

Push the

⬙ESC Off⬙ switch, to place the Electronic

Stability Control (ESC) system in

⬙Partial Off⬙ mode, before

rocking the vehicle. Refer to “Electronic Brake Control” in
“Safety” for further information. Once the vehicle has been
freed, push the

⬙ESC Off⬙ switch again to restore ⬙ESC On⬙

mode.

WARNING!

Fast spinning tires can be dangerous. Forces generated
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 vehicle’s wheels
faster than 30 mph (48 km/h) or for longer 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 transmission failure during pro-
longed efforts to free a stuck vehicle.

• When “rocking” a stuck vehicle by shifting between

DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain 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 transmis-
sion shifting occurring).

IN CASE OF EMERGENCY

429

TOWING A DISABLED VEHICLE

This section describes procedures for towing a disabled
vehicle using a commercial towing service. If the transmis-
sion and drivetrain are operable, disabled vehicles may
also be towed as described under “Recreational Towing” in
the “Starting And Operating” section.

NOTE:

Vehicles equipped with Quadra-Lift must be

placed in Transport mode, before tying them down (from
the body) on a trailer or flatbed truck. Refer to the section
on Quadra-Lift for more information. If the vehicle cannot
be placed in Transport mode (for example, engine will not
run), tie-downs should be fastened over the tires using
specific tire tie-down nets. Failure to follow these instruc-
tions may cause fault codes to be set and/or cause loss of
proper tie-down tension.

IN CASE OF EMERGENCY

Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other
equipment designed for this purpose, following equipment
manufacturer’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.

If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.

If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for towing.

CAUTION!

• Do not use sling type equipment when towing.

Vehicle damage may occur.

• When securing the vehicle to a flat bed truck, do not

attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.

Two-Wheel Drive Models

The manufacturer recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.

If flatbed equipment is not available, and the transmission
is operable, the vehicle may be towed (with rear wheels on
the ground) under the following conditions:
• The transmission must be in NEUTRAL. Refer to

⬙Manual Park Release⬙ in this section for instructions on
shifting the transmission to NEUTRAL when the engine
is off.

• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 30 miles (48 km).
If the transmission is not operable, or the vehicle must be
towed faster than 30 mph (48 km/h) or farther than 30
miles (48 km), tow with the rear wheels OFF the ground.
Acceptable methods are to tow the vehicle on a flatbed, or
with the front wheels raised and the rear wheels on a
towing dolly, or (when using a suitable steering wheel
stabilizer to hold the front wheels in the straight position)
with the rear wheels raised and the front wheels on the
ground.

IN CASE OF EMERGENCY

431

CAUTION!

• Towing faster than 30 mph (48 km/h) or farther than

30 miles (48 km) with rear wheels on the ground can
cause severe transmission damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.

Four-Wheel Drive Models

The manufacturer recommends towing with all wheels
OFF

the ground. Acceptable methods are to tow the vehicle

on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.

If flatbed equipment is not available, and the transfer case
is operable, vehicles with a two-speed transfer case may
be towed (in the forward direction, with ALL wheels on the
ground), IF the transfer case is in NEUTRAL (N) and the
transmission is in PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed instructions.

Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and therefore must be towed with
all four wheels OFF the ground.

CAUTION!

• Front or rear wheel lifts must not be used (if the

remaining wheels are on the ground). Internal dam-
age to the transmission or transfer case will occur if
a front or rear wheel lift is used when towing.

• Towing this vehicle in violation of the above require-

ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

Emergency Tow Hooks — If Equipped

If your vehicle is equipped with tow hooks, there will be
one in the rear and two mounted on the front of the vehicle.
The rear hook will be located on the driver’s side of the
vehicle.

NOTE:

For off-road recovery, it is recommended to use

both of the front tow hooks to minimize the risk of damage
to the vehicle.

432

IN CASE OF EMERGENCY

WARNING!

• Do not use a chain for freeing a stuck vehicle. Chains

may break, causing serious injury or death.

• Stand clear of vehicles when pulling with tow hooks.

Tow straps may become disengaged, causing serious
injury.

CAUTION!

Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.
