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 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 when 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,
(Continued)
WARNING! (Continued)
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.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, 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 for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
412 SERVICING AND MAINTENANCE

Automatic Transmission
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. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
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 transmis-
sion sealers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
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.
418 SERVICING AND MAINTENANCE

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.
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 contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
Front/Rear Axle Fluid
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. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 inch
(3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be tightened to 22
to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than 1/8 inch
(3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be tightened to 22
to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.

Automatic Transmission Use only Mopar ZF 8&9 Speed ATF Automatic Transmis-
sion Fluid or equivalent. Failure to use the correct fluid
may affect the function or performance of your transmis-
sion.
Transfer Case – Single-Speed We recommend you use Mopar ATF+4 Automatic Trans-
mission Fluid.
Axle Differential (Front) We recommend you use Mopar GL-5 Synthetic Axle Lubri-
cant SAE 75W-85.
Axle Differential (Rear) – With Electronic Limited-Slip

NOTE:
The “Forward Collision Warning Sensitivity” setting determines at what relative distance the vehicle directly in front
of you needs to be at, before the system warns you of a possible collision with the vehicle directly in front of you,
based on the option is selected. “Far” gives you the most amount of reaction time, whereas “Near” gives you the
least amount of reaction time, based on the distance between the two vehicles. ParkSense — If Equipped Sound Only Sound & Display
NOTE:
The “ParkSense” system setting scans for objects behind the vehicle when the transmission gear selector is in RE-
VERSE and the vehicle speed is less than 7 mph (11 km/h), when enabled. It provides an alert (audible and/or vi-
sual) to indicate the proximity to other objects. The system can be enabled with “Sound Only,” or “Sound & Display.” Rear ParkSense Chime Volume Low
