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 or in the ACC
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 ignition 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 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.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemental
Restraint System (SRS), the Redundant Air Bag
Warning Light will illuminate on the instrument
panel. The Redundant Air Bag Warning Light will stay on
until the fault is cleared. In addition, a single chime will
sound to alert you that the Redundant Air Bag Warning
Light has come on and a fault has been detected. If the
Redundant Air Bag Warning Light comes on intermittently
or remains on while driving have an authorized dealer
service the vehicle immediately
Úpage 63.
WARNING!
Ignoring the Air Bag Warning Light in your instrument
panel could mean you won’t have the air bag system to
protect you in a collision. If the light does not come on
as a bulb check when the ignition is first turned on,
stays on after you start the vehicle, or if it comes on as
you drive, have an authorized dealer service the air bag
system immediately.

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. If a Mopar® Engine Oil Filter is
unavailable, only use filters that meet or exceed
SAE/USCAR-36 Filter Performance Requirements.
ENGINE AIR CLEANER FILTER

T/A air filters are made of a unique, washable material.
Follow the recommended service interval as for non-T/A
air filters, substituting a cleaning for replacement.
Cleaning your engine air filter with the recommended
Mopar® Performance Air Filter Service Kit is not required
if you can still see any part of the wire screen on the entire
air filter regardless of how dirty it may appear. When any
part of the wire screen is no longer visible on the air filter,
that is an indication it is time to clean the air filter.
For cleaning instructions see steps 1-7 from the Shaker
Hood Air Filter Cleaning section
Úpage 232.
Unique for T/A, using the Mopar® Performance Air Filter
Service Kit, spray oil evenly along the crown of each filter
pleat holding the nozzle about 3 inches (76 mm) away
from the air filter. One spray per 2 square inches
(1,290 square mm) of air filter. With one complete coat of
oil, let it wick (saturate) for about 20 minutes, and if
required touch up any light areas on either side of the
filter.
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

ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated from
belt body)
 Rib or belt wear
 Longitudinal belt cracking (cracks between two ribs)
 Belt slips
 Groove jumping (belt does not maintain correct
position on pulley)
 Belt broken (identify and correct problem before new
belt is installed)
 Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle serviced
at an authorized dealer.
BODY LUBRICATION
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium-based grease, such
as Mopar® Spray White Lube to ensure quiet, easy
operation and to protect against rust and wear. Prior to the
application of any lubricant, the parts concerned should
be wiped clean to remove dust and grit; after lubricating,
excess oil and grease should be removed.
WARNING!
 Do not attempt to inspect an accessory drive belt
with vehicle running.
 When working near the radiator cooling fan, discon -
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition mode. You could be injured by the moving
fan blades.
 You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent
mechanic.

240SERVICING AND MAINTENANCE
BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically
Úpage 224.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder immediately if
the Brake System Warning Light indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“FULL” mark on the side of the master cylinder reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the 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.
However, low fluid level may be caused by a leak and a
checkup may be needed. Use only brake fluid that has been recommended by the
manufacturer, and has been kept in a tightly closed
container to avoid contamination from foreign matter or
moisture
Úpage 278.
CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a segregated volume
of fluid within the brake system master cylinder reservoir.
In the event of leakage or wear, use only the
manufacturer's recommended brake fluid
Úpage 278.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on the left
side of the transmission. The fluid level should be
1/4 inch (6.4mm) below the bottom of the fill hole.
Add fluid, if necessary, to maintain the proper level
Úpage 278.
Change Transmission Fluid
If contaminated with water, change the fluid immediately.
See an authorized dealer for service.
For the proper maintenance intervals
Úpage 224.
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 Úpage 278. 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 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 contaminate
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's recommended fluid may cause
deterioration in transmission shift quality and/or
damage to the transmission
Úpage 278.
