SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on others.
If you are not sure, ask an authorized dealer.
The air bag system must be ready to protect you in
a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your vehicle may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Occupant Classification System
Air Bag Warning Light
The Occupant Restraint Controller (ORC)
monitors the readiness of the electronic
parts of the air bag system whenever the
ignition switch is in the START or ON/RUN
position. If the ignition switch is in the OFF position,
the air bag system is not on and the air bags will
not inflate. The ORC contains a backup power supply system
that may deploy the air bag system even if the
battery loses power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch is
first in the ON/RUN position. After the self-check,
the Air Bag Warning Light will turn off. If the ORC
detects a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime will
sound to alert you if the light comes on again after
initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could affect
the air bag system. The diagnostics also record the
nature of the malfunction. While the air bag system
is designed to be maintenance free, if any of the
following occurs, have an authorized dealer
service the air bag system immediately.The Air Bag Warning Light does not come on
during the four to eight seconds when the igni
-
tion switch is first in the ON/RUN position.
The Air Bag Warning Light remains on after the
four to eight-second interval.
The Air Bag Warning Light comes on intermit -
tently or remains on while driving.
WARNING!
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR)
feature or any other seat belt function is not
working properly when checked according to
the procedures in the Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.

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 “Change Oil” or “Oil Change
Required” message is displayed. Have your 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 77.
NOTE:Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 km), one
year 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.
NOTE:The Oil Change Indicator will not illuminate under
these conditions. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs before
the oil indicator system turns on.
Check the fluid levels of the coolant reservoir,
and brake master cylinder reservoir, and fill as
needed.
Check function of all interior and exterior lights.

274SERVICING AND MAINTENANCE
Synthetic engine oils which do not have both the
correct API trademark and the correct SAE viscosity
grade numbers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an
authorized dealer, service station or governmental
agency for advice on how and where used oil and
oil filters can be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters
varies considerably. Only high quality Mopar®
certified filters should be used.
ENGINE AIR CLEANER FILTER
For the proper maintenance intervals Úpage 268.
Engine Air Cleaner Filter Selection
The quality of replacement filters varies
considerably. Only high quality Mopar® certified
filters should be used.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
WARNING!
The air induction system (air cleaner, hoses,
etc.) can provide a measure of protection in the
case of engine backfire. Do not remove the air
induction system (air cleaner, hoses, etc.) unless
such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle
with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in
serious personal injury.
WARNING!

Use only refrigerants and compressor lubri -
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty Infor -
mation Book, located in your owner’s informa -
tion kit, for further warranty information.

The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.
CAUTION!

Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air
conditioning components. Such damage is not
covered by the New Vehicle Limited Warranty.

282SERVICING AND MAINTENANCE
(Continued)
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. For the proper maintenance intervals
Ú page 268.
Brake Master Cylinder
The fluid in the master cylinder should be checked
when performing under hood services or
immediately if the Brake Warning Light is
illuminated.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to
bring the fluid level up to the requirements
described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the
brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low
fluid level may be caused by a leak and a checkup
may be needed. Use only the manufacturer recommended brake
fluid Ú
page 324.
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.

WARNING!
Use only the manufacturer recommended
brake fluid Úpage 324. 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 a 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.
