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 indicator message will illuminate in the
instrument cluster. This means that service is
required for your vehicle. Operating conditions such
as frequent short-trips, trailer tow, and extremely hot
or cold ambient temperatures will influence when
the “Oil Change Required” message is displayed.
Have the vehicle serviced as soon as possible, within
the next 500 miles (805 km).
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 Cluster Display
Ú
page 56.
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 engine oil level
Check windshield washer fluid level
Check the tire pressures and look for unusual
wear or damage. Rotate at the first sign of irreg
-
ular wear, even if it occurs before the oil indi -
cator system turns on
Check the fluid levels of the coolant reservoir,
and brake master cylinder and fill as needed
Check function of all interior and exterior lights

Coolant Level
The coolant expansion bottle provides a quick
visual method for determining that the coolant
level is adequate. With engine off and cold, the
level of the engine coolant (antifreeze) in the bottle
should be between the “MIN” and “MAX” marks.
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.
BRAKE SYSTEM
In order to ensure brake system performance, all
brake system components should be inspected
periodically Ú page 199.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood service
or immediately if the Brake System Warning Light
indicates system failure. If necessary, add fluid to
bring level within the designated marks on the side
of the reservoir of the brake master cylinder. Be
sure to clean the top of the master cylinder area
before removing cap. With disc brakes the fluid
level can be expected to fall as the brake linings
wear. However, an unexpected drop in fluid level
may be caused by a leak and a system check
should be conducted Ú page 251.
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 high brake temperatures, excessive
lining wear, and possible brake damage. You
would not have your full braking capacity in an
emergency.

212SERVICING AND MAINTENANCE
AUTOMATIC TRANSMISSION
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use the manufacturer specified transmission
fluid Úpage 252. 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.

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. The only exception to this policy is the use of
special dyes for diagnosing fluid leaks in 9-speed
transmissions. 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 filler tube is
capped and no dipstick is provided. An authorized
dealer can check your transmission fluid level
using a special service dipstick. 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 the manufacturer recommended
brake fluid Ú
page 251. 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 contami -
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.

CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 252.
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.

252TECHNICAL SPECIFICATIONS
CHASSIS FLUIDS AND LUBRICANTS
CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant (antifreeze) or any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) 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 antirust 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 (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
Component Fluid, Lubricant, Or Genuine Part
Automatic TransmissionUse only Mopar® ZF 8 & 9 Speed ATF Automatic Transmission Fluid or equivalent. Failure to use the correct fluid may
affect the function or performance of your transmission.
Brake Master Cylinder We recommend using Mopar® DOT 4. DOT 4 brake fluid must be changed every two years regardless of mileage.
