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 AVV/START or
MAR/ACC/ON/RUN position. If the ignition switch is in the
STOP/OFF/LOCK 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 in the MAR/ACC/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 ignition switch is first in the
MAR/ACC/ON/RUN position.
• The Air Bag Warning Light remains on after the four to eight-second interval.
• The Air Bag Warning Light comes on intermittently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine related gauges
are not working, the Occupant Restraint Controller (ORC)
may also be disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an authorized
dealer service the air bag system immediately.

STARTING AND OPERATING 171
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.

If for some reason the power assist is interrupted, it will still be
possible to steer your vehicle. Under these conditions, you will
observe a substantial increase in steering effort, especially at
very low vehicle speeds and during parking maneuvers.

NOTE:
• Increased noise levels at the end of the steering wheeltravel are considered normal and do not indicate that there
is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steering pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked if
a leak is suspected, abnormal noises are apparent, and/or
the system is not functioning as anticipated. Coordinate
inspection efforts through your authorized dealer. CAUTION!
Prolonged operation of the steering system at the end of
the steering wheel travel will increase the steering fluid
temperature and it should be avoided when possible.
Damage to the power steering pump may occur.
WARNING!
Fluid level should be checked on a level surface and with
the engine off to prevent injury from moving parts and
to ensure accurate fluid level reading. Do not overfill.
Use only manufacturer's recommended power steering
fluid.

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 indi-
cator message will illuminate. This means that service is
required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, extended engine idle time,
extremely hot or cold ambient temperatures will influence
when the “Oil Change Required” message is displayed.
Severe Operating Conditions can cause the change oil
message to illuminate as early as 3,500 miles (5,600 km) since
last reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).

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 “Oil
Change Reset” in “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
NOTE:
Under no circumstances should oil change intervals exceed
10,000 miles (16,000 km), 350 hours of engine run time or
12 months, whichever comes first. The 350 hours of engine run
or idle time is generally only a concern for fleet customers.

Severe Duty All Models

Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of engine
run time if the vehicle is operated in a dusty and off road environ -
ment or is operated predominantly at idle, or only very low engine
RPM. This type of vehicle use is considered Severe Duty.

Once A Month Or Before A Long Trip:
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure 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, fill as needed.
• Check function of all interior and exterior lights.

250 SERVICING AND MAINTENANCE
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its perfor -
mance 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, indiscrimi -
nately discarded, can present a problem to the environment.
Contact an authorized dealer, service station or govern -
mental 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

This manufacturer's engines have a full-flow type disposable oil
filter. Use a filter of this type for replacement. The quality of
replacement filters varies considerably. Only high quality filters
should be used to ensure most efficient service. Mopar engine
oil filters are high quality oil filters and are recommended.

Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this chapter for the
proper maintenance intervals.
NOTE:
Be sure to follow the “Severe Duty Conditions” maintenance
interval if applicable.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to
ensure most efficient service. Mopar engine air cleaner filters
are a high quality filter and are recommended.
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.

260 SERVICING AND MAINTENANCE
(Continued)
Brake System
In order to ensure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
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 fallas 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 manufacturer's recommended brake fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
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 manufacturer's recommended brake fluid. Refer to “Fluids And Lubricants” in “Technical Speci -
fications” for further information. 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 mois -
ture, 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 unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.
