Place the jack under the axle tube, as shown. Do not raise
the vehicle until you are sure the jack is fully engaged.
5. Raise the vehicle by turning the jack screw to the right.
Raise the vehicle only until the tire just clears the surface and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
6. Remove the lug nuts and wheel.
7. Position spare wheel/tire on vehicle and install lug
nuts with cone-shaped end toward wheel. Lightly tighten
nuts clockwise. To avoid the risk of forcing the vehicle off
the jack, do not tighten the nuts fully until the vehicle has
been lowered.
8. Lower the vehicle by turning the jack screw to the left,
and remove the jack and wheel blocks.

fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-

any other booster source that has a greater than
12–volt system, i.e. do not use a 24–volt power
source.
Your vehicle is equipped with a 12–volt battery. If it
becomes necessary to use a booster battery, with jumper
cables, to start the vehicle’s engine because it’s battery is
discharged, the following procedure should be followed:

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.
268 MAINTAINING YOUR VEHICLE

•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C)
•Taxi, Police, or delivery service (commercial service)
•Trailer towing
•Off-road or desert driving
•If equipped for and operating with E–85 (ethanol) fuel
If ANY of these apply to you, then change your engine oil
at every interval shown in schedule “B” of the “Mainte-
nance Schedules” section of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule “A” of the “Main-
tenance Schedules” section of this manual
NOTE: Under no circumstances should oil change in-
tervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of DaimlerChrysler
Material Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.

To minimize the possibility of catalytic converter dam-
age:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing.
•Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating conditions.
•Do not allow vehicle to run out of fuel.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Engine Timing Belt — 2.4L Engine
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Ignition Wiring System — 2.4L Engine
Replace the ignition cables at the intervals described in
the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.

material, as damage may result.
•Do not allow any vinyl cleaner to run down and dry
on the paint, leaving a streak.
•After cleaning your vehicle’s fabric top, always make
sure it is completely dry before lowering.
•Be especially careful when washing the windows by
following the directions for “Care of Fabric Top Win-
dows.”
WASHING — Use MoparCar Wash or mild soap suds,
lukewarm water, and a brush with soft bristles. If extra

which can be scratched unless special care is taken
by following these directions:
1. Never use a dry cloth to remove dust. Instead, use a
microfiber towel or soft cotton cloth moistened with
cold or warm, clean water, and wipe across the window,
not up and down. MoparJeep Soft Glass Window
Cleaner will safely clean all plastic windows without
scratching. Removes fine scratches to improve visibility
and provide UV protection to help prevent yellowing.

FUSE PANEL
Interior Fuses
The fuse panel is located behind the glove box. To access the fuse panel the glove box must be removed.
It is removed by slipping the glove box strap off the hook
and letting the door roll down off its hinges. To reinstall,
position the glove box door at an 8 o’clock orientation,
engage the hinge hook formations on the lower edge of
the glove box door with the hinge pins on the lower edge
of the instrument panel. Tilt the upper edge of the glove
box door upward toward the instrument panel enough to
reattach the glove box strap to the door. Rotate glove box
door to closed position. Open and close to insure proper
installation.
