HECKING

EVEL

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

month. 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.
Adding 1 quart (1.0 liters) 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.

The windshield washer fluid reservoir is located in

the front of the engine compartment. Be sure to

check the fluid level at regular intervals. Fill the

reservoir with windshield washer solvent (not

radiator antifreeze) and operate the system for a

few seconds to flush out the residual water.
When refilling the washer fluid reservoir, apply

some washer fluid to a cloth or towel and wipe the

wiper blades clean. 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.
The fluid reservoir will hold nearly 1 gallon (4 liters)

of washer fluid when the message “Low Washer

Fluid” appears in the instrument cluster.

Under normal operating conditions, the catalytic

converter 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 emission 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. Service, including a

tune-up to manufacturer's specifications, should

be obtained immediately.
To minimize the possibility of catalytic converter

damage:



Do not shut off the engine or interrupt the igni

tion when the transmission is in gear and the

vehicle is in motion.



Do not try to start the engine by pushing or

towing the vehicle.



Do not idle the engine with any spark plug wires

disconnected or removed, such as when diag

nostic testing, or for prolonged periods during

very rough idle or malfunctioning operating

conditions.

NOTE:

Your vehicle’s exhaust system may be equipped

with an Electronic Exhaust Valve (EEV) system, if

the exhaust system is replaced with aftermarket

products a Malfunction Indicator Lamp (MIL) will

illuminate.

WARNING!



Exhaust gases can injure or kill. They contain

carbon monoxide (CO), which is colorless and

odorless. Breathing it can make you uncon

scious and can eventually poison you. To

avoid breathing CO

page 191.



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 involving engine misfire or other

apparent loss of performance, have your

vehicle serviced promptly. Continued opera

tion of your vehicle with a severe malfunction

could cause the converter to overheat,

resulting in possible damage to the converter

and vehicle.

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 compat

ible” coolant. If a non-OAT engine coolant is

introduced into the cooling system in an emer

gency, the cooling system will need to be

drained, flushed, and refilled with fresh OAT

coolant (conforming to MS.90032), by an autho

rized dealer as soon as possible.



Do not use water alone or alcohol-based engine

coolant 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

propylene glycol-based engine coolant. Use of

propylene 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 coolant is needed to be added to

the system please contact an authorized dealer.

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 radi

ator 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,

disconnect the fan motor lead or turn the igni

tion to the OFF position. The fan is tempera

ture controlled and can start at any time the

SERVICING AND MAINTENANCE

225

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 that you use the same engine

coolant (OAT coolant 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:



We recommend using Mopar® Antifreeze/

Coolant 10 Year/150,000 Mile (240,000 km)

Formula OAT that meets the requirements of the

manufacturer Material Standard 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

deionized 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.



Some vehicles require special tools to add

coolant properly. 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 a local authorized

dealer.



Mixing engine coolant types is not recom

mended 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

equipped.

The cap should be inspected and cleaned if there

is any accumulation of foreign material on the

sealing surfaces.

Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) is

a regulated substance requiring proper disposal.

Check with your local authorities to determine the

disposal rules for your community. To prevent

ingestion 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

by a child or pet, seek emergency assistance

immediately.

WARNING!



Do not open a 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 scalding 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.

226

SERVICING AND MAINTENANCE

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 replacing coolant. Advise your

service attendant of this. As long as the engine

operating temperature is satisfactory, the coolant

bottle need only be checked once a month.
When additional engine coolant is needed to

maintain the proper level, only OAT coolant that

meets the requirements of FCA Material Standard

MS.90032 should be added to the coolant bottle.

Do not overfill.

Cooling System Notes

NOTE:

When the vehicle is stopped after a few miles/kilo

meters of operation, you may observe vapor

coming from the front of the engine compartment.

This is normally a result of moisture from rain,

snow, or high humidity accumulating on the

radiator and being vaporized when the thermostat

opens, allowing hot engine coolant (antifreeze) to

enter the radiator.

If an examination of your engine compartment

shows no evidence of radiator or hose leaks, the

vehicle may be safely driven. The vapor will soon

dissipate.



Do not overfill the coolant expansion bottle.



Check the coolant freeze point in the radiator

and in the coolant expansion bottle. If engine

coolant needs to be added, the contents of the

coolant expansion bottle must also be protected

against freezing.



If frequent engine coolant additions are

required, the cooling system should be pressure

tested for leaks.



Maintain engine coolant concentration at a

minimum of 50% OAT coolant (conforming to

MS.90032) and distilled water for proper corro

sion protection of your engine which contains

aluminum components.



Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.



Keep the front of the radiator clean. If your

vehicle is equipped with air conditioning, keep

the front of the condenser clean.



Do not change the thermostat for Summer or

Winter operation. If replacement is ever neces

sary, install ONLY the correct type thermostat.

Other designs may result in unsatisfactory

engine cooling performance, poor gas mileage,

and increased emissions.

Special Additives

The manufacturer strongly recommends against

using any special additives in the transmission.

Automatic Transmission Fluid (ATF) is an

engineered product and its performance may be

impaired by supplemental additives. Therefore, do

not add any fluid additives to the transmission.

Avoid using transmission sealers as they may

adversely affect seals.

Fluid Level Check

The fluid level is preset at the factory and does not

require adjustment under normal operating

conditions. Routine fluid level checks are not

required; therefore the transmission has no

dipstick. An authorized dealer can check your

transmission fluid level using special service tools.

If you notice fluid leakage or transmission

malfunction, visit an authorized dealer

immediately to have the transmission fluid level

checked. Operating the vehicle with an improper

fluid level can cause severe transmission damage.

WARNING!



Use only manufacturer's recommended brake

fluid

page 269. Using the wrong type of

brake fluid can severely damage your brake

system and/or impair its performance. The

proper type of brake fluid for your vehicle is

also identified on the original factory installed

hydraulic master cylinder reservoir.



To avoid contamination from foreign matter or

moisture, use only new brake fluid or fluid that

has been in a tightly closed container. Keep

the master cylinder reservoir cap secured at

all times. Brake fluid in an open container

absorbs moisture from the air resulting in a

lower boiling point. This may cause it to boil

unexpectedly during hard or prolonged

braking, resulting in sudden brake failure. This

could result in a collision.

Overfilling the brake fluid reservoir can result

in spilling brake fluid on hot engine parts,

causing the brake fluid to catch fire. Brake

fluid can also damage painted and vinyl

surfaces, care should be taken to avoid its

contact with these surfaces.



Do not allow petroleum based fluid to contam

inate the brake fluid. Brake seal components

could be damaged, causing partial or

complete brake failure. This could result in a

collision.

WARNING!

CAUTION!

Do not use chemical flushes in your

transmission as the chemicals can damage your

transmission components. Such damage is not

covered by the New Vehicle Limited Warranty.

CAUTION!

If a transmission fluid leak occurs, visit an

authorized dealer immediately. Severe

transmission damage may occur. An authorized

dealer has the proper tools to adjust the fluid

level accurately.

SERVICING AND MAINTENANCE

(Continued)

Fluid And Filter Changes

Under normal operating conditions, the fluid

installed at the factory will provide satisfactory

lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.

However, change the fluid and filter if the fluid

becomes contaminated (with water, etc.), or if the

transmission is disassembled for any reason.

Selection Of Lubricant

It is important to use the proper transmission fluid

to ensure optimum transmission performance and

life. Use only the manufacturer's specified

transmission fluid

page 269. It is important to

maintain the transmission fluid at the correct level

using the recommended fluid.

NOTE:

No chemical flushes should be used in any trans

mission; only the approved lubricant should be

used.

(AWD) — I

QUIPPED

The All Wheel Drive system consists of a transfer

case and front differential. The exterior surface of

these components should be inspected for

evidence of fluid leaks. Confirmed leaks should be

repaired as soon as possible.
The transfer case fluid fill/inspection plug is

located in the middle of the rear housing. To

inspect the transfer case fluid level, remove the

fill/inspection plug. The fluid level should be even

with the bottom of the hole. Use this plug to add

fluid as required.
The front differential fill plug is located on the outer

cover near the half shaft attachment. To inspect

the differential fluid level, remove the fill plug. The

fluid level should be even with or slightly below the

bottom of the hole.

Fluid Changes

For normal service, periodic fluid level checks are

not required. When the vehicle is serviced for other

reasons the exterior surfaces of the axle assembly

should be inspected. If gear oil leakage is

suspected inspect the fluid level

USES

General Information

CAUTION!

Using a transmission fluid other than the

manufacturer’s recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder

page 269.

WARNING!



When replacing a blown fuse, always use an

appropriate replacement fuse with the same

amp rating as the original fuse. Never replace

a fuse with another fuse of higher amp rating.

The use of a fuse with a rating other than indi

cated may result in a dangerous electrical

system overload. If a properly rated fuse

continues to blow, it indicates a problem in the

circuit that must be corrected. Never replace a

blown fuse with metal wires or any other mate

rial. Do not place a fuse inside a circuit

breaker cavity or vice versa. Failure to use

proper fuses may result in serious personal

injury, fire and/or property damage.

SERVICING AND MAINTENANCE

229

The fuses protect electrical systems against

excessive current.
When a device does not work, you must check the

fuse element inside the blade fuse for a break/

melt.
Also, please be aware that using power outlets for

extended periods of time with the engine off may

result in vehicle battery discharge.

Blade Fuses

Underhood Fuses

The Front Power Distribution Center is located in

the engine compartment. This module contains

fuses and relays. Fuse cavity location and

descriptions are printed on the inside of the power

distribution center cover.



Before replacing a fuse, make sure that the

ignition is off and that all the other services

are switched off and/or disengaged.



If the replaced fuse blows again, contact an

authorized dealer.



If a general protection fuse for safety systems

(air bag system, braking system), power unit

systems (engine system, transmission

system) or steering system blows, contact an

authorized dealer.

WARNING!

1 — Fuse Element
2 — Blade Fuse with a good/ functional fuse

element
3 — Blade fuse with a bad/ not functional fuse

element (blown fuse)

CAUTION!



When installing the power distribution center

cover, it is important to ensure the cover is

properly positioned and fully latched. Failure

to do so may allow water to get into the power

distribution center and possibly result in an

electrical system failure.
