JUMP-STARTING PROCEDURES
WARNING!
²Take care to avoid the radiator cooling fans whenever the hood
is raised. They can start anytime the ignition switch is on. You
can be hurt by the fans.
²Take care to avoid the accessory drive whenever the hood is
raised. You can be hurt by the moving components.
²Do not attempt to push or tow your vehicle to get it started.
Unburned fuel could enter the catalytic converter and once the
engine has started, ignite and damage the converter and
vehicle. If the vehicle has a discharged battery, booster cables
may be used to obtain a start from a booster battery or the
battery in another vehicle. This type of start can be dangerous
if done improperly, so follow this procedure carefully.
²Battery fluid is a corrosive acid solution; do not allow battery
fluid to contact eyes, skin, or clothing. Don't lean over battery
when attaching clamps or allow the clamps to touch each
other. If acid splashes in eyes or on skin, flush contaminated
area immediately with large quantities of water.
²A battery generates hydrogen gas, which is flammable and
explosive. Keep flame or spark away from the vent holes.
²Do not use a booster battery or any other booster source with
an output that exceeds 12 volts.
NOTE:The battery is located underneath an access
panel inside the rear compartment on the left side of the
vehicle. A remote battery terminal is located in the engine
compartment for jump-starting.
1. Wear eye protection and remove any metal jewelry
such as watchbands or bracelets that might make an
inadvertent electrical contact.
2. When boost is provided by a battery in another
vehicle, park that vehicle within booster cable reach, but
without allowing the vehicles touch one another.
3. Set the parking brake, place the transmission in neu-
tral, and turn the ignition OFF on both vehicles.
4. Turn off the heater, radio, and all unnecessary electri-
cal loads.
186 WHAT TO DO IN EMERGENCIES

WARNING!
²You should not try to start your vehicle by pushing
or towing.
²Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
²During cold weather when temperatures are be-
low freezing point, electrolyte in a discharged
battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode. The
battery temperature must be brought up above
freezing point before attempting jump-start.10. Start the engine in the vehicle that has the booster
battery. Let the engine idle a few minutes.
11. Turn off the Vehicle Security System.
NOTE:The Vehicle Security System will prevent the
engine from starting.
12. Start the engine in the vehicle with the discharged
battery. If engine does not start in 15 seconds, stop
cranking engine and allow starter to cool down before
cranking again.
13. When removing the booster cables, reverse the above
sequence exactly. Be careful of the moving belts and fans.
188 WHAT TO DO IN EMERGENCIES

WARNING!
Any procedure other than above could result in:
1. Personal injury caused by electrolyte squirting out
the battery vent;
2. Personal injury or property damage due to battery
explosion;
3. Damage to charging system of booster vehicle or
of immobilized vehicle.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or snow, it
can often be moved by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between Reverseand First gear. Usually the least accelerator pedal pres-
sure to maintain the rocking motion without spinning the
wheels is most effective.
CAUTION!
Racing the engine or spinning the wheels too fast
may lead to transmission/axle overheating and fail-
ure. It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h).
TOWING A DISABLED VEHICLE
Do not tow with sling type equipment. Only use flat bed
equipment. Always comply with applicable state or local
towing ordinances.

CAUTION!
Towing with equipment other than flat bed types
may damage your vehicle.
190 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This system
monitors the performance of the emissions and engine
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions 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. Although your
vehicle will usually be drivable and not need towing, see
your dealer for service as soon as possible.CAUTION!
Prolonged driving with the 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 state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
If the gas cap is not tightened properly, the light may
come on. Be sure the gas cap is tightened every time you
add fuel.

²More than 50% of your driving is at sustained high
speeds during hot weather, above 90ÉF (32ÉC)
²Trailer towing
²Taxi, Police, or delivery service (commercial service)
²Off-road or desert driving
²If 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 ªBº in the
9Maintenance Schedules9in this manual.
If none of these applies to you, then change your engine
oil at every interval shown on schedule9A9in the
9Maintenance Schedules9in 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 under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SM or
SM/CF, and meet the requirements of DaimlerChrysler
Material Standard MS-10725.
The manufacturer recommends the use of a full synthetic
engine oil, such as Mobil 1tSAE 0W-40 or equivalent.
Engine Oil Viscosity (SAE Grade)
The proper SAE viscosity grade of engine oil should be
selected based on the following recommendation and be
within the operating temperature shown in the engine oil
viscosity chart.
200 MAINTAINING YOUR VEHICLE

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming in contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine off, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer's
specifications immediately.
To minimize the possibility of catalytic converter damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
²Do not try to start the engine by pushing or towing the
vehicle.
²Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Ignition Wiring System and Ignition Timing
The ignition cables should be kept clean and the termi-
nals fully seated. Do not remove the nipple assemblies
from the coil towers. Cracked, damaged, or faulty cables
should be replaced. See your authorized dealer for ser-
vice.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typemust be done at the times or mileages specified to
assure the continued proper functioning of the emission
control system. These, and all other maintenance services

tenance may be needed for vehicles in severe operating
conditions such as dusty areas and very short trip
driving.
Inspection and service also should be done anytime a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part, which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.
