CAUTION!The winch mechanism is designed for use with the
winch “ T ” handle only. Use of an air wrench or other
power tools is not recommended and can damage the
winch.
3. Assemble the winch handle extensions to form the
Spare Tire Hook and pull the compact spare tire/cover
assembly from under the vehicle. WARNING!Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift. WHAT TO DO IN EMERGENCIES 351

10. Lower the vehicle by turning the jack screw to the
left.
11. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N · m (95 ft. lbs). If in doubt
about the correct tightness, have them checked with a
torque wrench by your dealer or at a service station.
12. Lower the jack to its fully closed position.
13. Secure the flat tire as follows:
• Place the deflated (flat) tire and compact spare tire
cover assembly in the rear cargo area, have the tire
repaired or replaced as soon as possible. WARNING!A loose deflated (flat) tire thrown forward in a
collision or hard stop could injure the occupants in
the vehicle. Have the deflated (flat) tire repaired or
replaced immediately.
CAUTION!Vehicle damage will occur if the compact spare tire
cover assembly is installed without the compact
spare tire in position. Place the deflated (flat) tire
and compact spare tire cover assembly in the rear
cargo area.
14. Stow the cable and wheel spacer before driving the
vehicle, reassemble the winch handle extensions to form
a “ T ’ and fit the winch “ T ” handle over the drive nut. WHAT TO DO IN EMERGENCIES 355

10. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
lug nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N · m (95 ft. lbs). If in doubt

11. Lower the jack to its fully closed position. WARNING!A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
12. Secure the flat or spare tire as follows:
• If your vehicle is equipped with cast aluminum
wheels, the center cap of the wheel must be re-
moved prior to flat tire stowage. Store the center cap
inside the glove box or other storage compartment.
• Turn the wheel so that the valve stem is down. Slide
the wheel retainer through the center of the wheel
and position it properly across the wheel opening.364 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “ Malfunction Indicator Light. ” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible. CAUTION!• Prolonged driving with the “ Malfunction Indica-
tor Light ” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
• If the “ Malfunction Indicator Light ” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.376 MAINTAINING YOUR VEHICLE

EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle ’ s emissions control system.
Failure to pass could prevent vehicle registration.
For states which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system may not be ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test. Your vehicle has a simple ignition key actuated test
which you can use prior to going to the test station. To
check if your vehicle ’ s OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off the MAINTAINING YOUR VEHICLE 377

ignition key or start the engine. This means that your
vehicle ’ s OBD system is not ready and you should not
proceed to the I/M station.
b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or start
the engine. This means that your vehicle ’ s OBD system
is ready and you can proceed to the I/M station.
If your OBD system is not ready, you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle ’ s OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Mopar  parts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Mopar  parts for maintenance
and repairs will not be covered by the manufacturer ’ s
warranty.
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.378 MAINTAINING YOUR VEHICLE

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 the required maintenance
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 engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. MAINTAINING YOUR VEHICLE 379
