Fluid Leaks
Check the area under vehicle after overnight parking for
fuel, water, oil, or other fluid leaks. Also, if gasoline
fumes are detected, the cause should be located and
corrected.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 67

11. Liftgate Open
The Gate Open light will illuminate when the liftgate is
not properly closed.
12. Security Light
This light will flash rapidly for approximately 15 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower speed continuously after the alarm is set.
The security light will also come on for about three
seconds when the ignition is first turned on.
13. ABS Warning Light
This light monitors the Anti-Lock Brake System
which is described elsewhere in this manual.
This light will come on when the ignition key is
turned to the ON position and may stay on for
approximately 3 seconds. If this light remains on or
comes on during driving, it indicates that the Anti-Lockportion of the brake system is not functioning and that
service is required. See your authorized dealer immedi-
ately.
14. Engine Oil Pressure Indicator Light
This light indicates that the engine oil pressure has
become too low. For a bulb check, this light will
come on momentarily when the ignition is turned On. If
the light turns on while driving, stop the vehicle and shut
off the engine as soon as possible. Immediate service
should be obtained. (See page 311 for more information.)
15. Tachometer
This gauge measures engine revolutions-per-minute
(rpm x 1000).
16. Gear Selector
The electronic gear selector display is self-contained
within the instrument cluster. It displays the position of
the automatic transmission shift lever, and the relation of
each position to all other positions. For a good signal the

WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel. Lightly tighten the nuts. To
avoid risk of forcing the vehicle off the jack, do not fully
tighten the nuts until the vehicle has been lowered.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.
6. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 85-115 ft. lbs.
(115-155 N·m) torque. If in doubt about the correct
tightness, have them checked with a torque wrench by
your dealer or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack, tools and the extra tire and
wheel in the places provided.
7. Remove wheel blocks. Do not install chrome or alu-
minum wheel center caps on the spare wheel. This may
result in cap damage.
8. Lower the jack to its fully closed position. Stow the
replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

Engine Oil
Checking Engine Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. The
best time to check the engine oil level is about 5 minutes
after a fully warmed up engine is shut off or before
starting the engine after it has sat overnight.
1. Position the vehicle on a level surface.
2. Turn Off the engine and allow approximately 5 min-
utes for the oil to settle to the bottom of the crankcase.
3. Remove the engine oil level indicator (dipstick).
4. Wipe the engine oil level indicator (dipstick) clean.
5. Install the engine oil level indicator (dipstick) and
make sure it is seated in the tube.
6. Remove the engine oil level indicator (dipstick), keep-
ing the handle above the tip, and read the oil level on the
engine oil level indicator (dipstick).7. Add oil only if the level is below the “SAFE” range (at
or below the “ADD” mark) on the engine oil level
indicator (dipstick). Adding one quart of oil when the
reading is at the ADD mark will result in a reading at the
top of the SAFE range..

CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Frequency Of Oil Change
Road conditions and your style of driving affect the
interval at which your oil should be changed. Check the
following to determine ifANYapply to you:
•Day or night temperatures are below 32°F (0°C).
•Stop and Go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16.2 km).
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C).
•Trailer towing, Taxi, Police or delivery service (com-
mercial service).
•Off-Road or desert operation.
•If equipped for and operating with E-85 (ethanol)
fuel.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
4x4 Models, If Used Primarily For Off-Road Operation

Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner and the crankcase inlet air cleaner. The
crankcase ventilation system should also be checked
periodically. Make sure that these units are always clean.
This will tend to reduce to a minimum the amount of
abrasive material that may enter the engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacture only
recommends engine oils that are API certified and meet
the requirements of DaimlerChrysler Material Standard
MS-6395. Use Mopar or an equivalent oil meeting the
specification MS-6395.
Engine Oil Identification (API) Symbol
There is a symbol to aid you in selecting the proper
engine oil.
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils that
meet the requirements of
DaimlerChrysler Material Stan-
dard MS-6395. Use Mopar or an
equivalent oil meeting the specifi-
cation MS-6395.
Engine Oil Viscosity (SAE Grade)
For 3.7L/4.7L engines SAE 5W-30 engine oil is recom-
mended for all operating temperatures. For 5.7L en-
gines SAE 5W-20 engine oil is recommended for all
operating temperatures.These engine oils improve low

Engine Oil Filter Selection
The manufacturer’s engines have a full-flow type 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 assure most efficient
service. MoparEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tensioner
Belt tension is controlled by means of an automatic
tensioner. No belt tension adjustments are required.
However, belt and belt tensioner condition should be
inspected at the specified intervals, and replaced if re-
quired. See your authorized dealer for service. At the
mileage indicated in the maintenance schedule, all belts
and tensioner should be checked for condition. Improper
belt tension can cause belt slippage and failure. Belts
should be inspected for evidence of cuts, cracks, glazing,
or frayed cords and replaced if there is indication of
damage which could result in belt failure. Low generatorbelt tension can cause battery failure. Also check belt
routing to make sure there is no interference between the
belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure proper engine
performance and emission control. The plugs installed in
your vehicle should operate satisfactorily in normal
service for the mileage indicated in the Maintenance
Chart. New plugs should be installed at this mileage. The
entire set should be replaced if there is any malfunction
due to a faulty spark plug. Check the Vehicle Emissions
Control Information label for the proper type of spark
plug for your vehicle.
