Lights
Check the operation of all exterior lights. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for positive closing, latching and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
water, oil, or other fluid leaks. Also, if fuel fumes are
detected the cause should be located and corrected.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

11. 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.
12. 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-Lock
portion of the brake system is not functioning and that
service is required. See your authorized dealer immedi-
ately.13. 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.
14. Tachometer
This gauge measures engine revolutions-per-minute
(rpm x 1000).
15. 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
display will place a box around the selected transmission

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.
6. Using the wheel wrench, finish tightening the nuts in
a crisscross pattern. Correct nut tightness is 130-160 ft.
lbs. (177-217 N·m). 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. Lower the jack to its fully closed position. Stow the
replaced tire, jack, and tools as previously described.
8. Adjust the tire pressure when possible.
NOTE:Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

could adversely affect the engine or vehicle performance.
These items should be inspected if a malfunction is
observed or suspected.
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.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.

Change Engine Oil
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.
IfNONEof these apply to you, then change your engine
oil every 6,000 miles (10 000 km) or 6 months, whichever
comes first and follow scheduleAof theMaintenance
Schedulessection 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.

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. 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.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacture only recommends
API Certified engine oils.
Engine Oil Viscosity (SAE Grade)
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low tempera-
ture starting and vehicle fuel economy. Your engine oil
filler cap also shows the recommended engine oil
viscosity for your vehicle.
For information on engine oil filler cap location, see the
Engine Compartment illustration in this section.

Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
Windshield Washers
The fluid reservoir should be checked for fluid level at
regular intervals. When freezing weather is anticipated,
flush out the water in the reservoir by operating the
system. Fill the reservoir with windshield washer anti-
freeze (not radiator antifreeze), and operate the system
for a few seconds to flush out the residual water.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.
After the engine has warmed, operate the defroster for a
few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. MoparAll
Weather Windshield Washer Solution used with water as
directed on the container, aids cleaning action, reduces
freezing point to avoid line clogging, and is not harmful
to paint or trim.
