puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills 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 (antifreeze) 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 (antifreeze) 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.Points To Remember
NOTE:
When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized 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.
644 MAINTAINING YOUR VEHICLE

•Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
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 necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased emis-
sions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally

MAINTAINING YOUR VEHICLE 645

WARNING!(Continued)
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed 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 contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
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, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 in
(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).7
MAINTAINING YOUR VEHICLE 647

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 supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. Avoid using transmission seal-
ers 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. Your authorized dealer can
check your transmission fluid level using special service
tools.
If you notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the
transmission fluid level checked. Operating the vehicle
with an improper fluid level can cause severe transmis-
sion damage.
CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission dam-
age may occur. Your authorized dealer has the proper
tools to adjust the fluid level accurately.
650 MAINTAINING YOUR VEHICLE

Your 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 your authorized dealer, the message can be reset by
referring to the steps described under “Driver Informa-
tion Display (DID)” in “Understanding Your Instrument
Panel” for further information.
At Each Stop For Fuel
•Check the engine oil level. Refer to “Maintenance
Procedures/Engine Oil” in “Maintaining Your Ve-
hicle” for further information.
• Check the windshield washer solvent and add if
required.
Once A Month
• Check tire pressure and look for unusual wear or
damage. •
Inspect the battery, and clean and tighten the terminals
as required.
• Check the fluid levels of the coolant reservoir, engine
oil, brake master cylinder, and add as needed.
• Check all lights and other electrical items for correct
operation.
At Each Oil Change
• Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
