(ABS) described elsewhere in this manual. This
light will come on when the ignition switch is turned to
the ON position and may stay on for as long as three
seconds.
If the light comes back on immediately or comes on
during driving, it indicates that the Anti-Lock portion of
the brake system is not functioning and that service is
required, however, the conventional brake system will
continue to operate normally provided that the BRAKE
warning light is not on. Also, a chime will sound if the

Anti-Lock brakes (ABS), it may also indicate an ABS
malfunction that could lead to reduced braking perfor-
mance.WARNING!
Driving a vehicle with the BRAKE warning light on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.
The operation of the BRAKE warning light can be
checked by turning the ignition switch from the OFF
position to the ON position. The light should illuminate
for approximately two seconds. The light should then

DEALER SERVICE
Your dealer has the qualified service personnel, special tools
and equipment to perform all service operations in an
expert manner. Service Manuals are available which include
detailed service information for your vehicle. Refer to these
manuals before attempting any procedure yourself.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Do only that 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.
MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides the maintenance items for which there are fixed
maintenance intervals, there are other items that should
operate satisfactorily without periodic maintenance.
However, if a malfunction of these items does occur, it
could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals, such as every fuel stop.
312 MAINTAINING YOUR VEHICLE

Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil and oil filters, indiscriminately
discarded, can present a problem to the environment.
Contact your authorized dealer, service station, or gov-
ernmental agency for advice on how and where used oil
can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of the manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Moparengine oil filters are high
quality oil filters and are recommended.
Drive Belts — Check Condition and Tension
At the mileage shown in the appropriate “Maintenance
Schedule,” check all drive belts for condition and proper
tension. Improper belt tension can cause belt slippage
and failure.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specifications
and procedures shown in the Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
