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.7. If the vehicle is equipped with Sentry Key Immobi-
lizer, turn the ignition switch to the ON position for 3
seconds before moving the ignition switch to the START
position.
8. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
9. When removing the jumper cables, reverse the above
sequence exactly. Be careful of the moving belts and fan.

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.
TOWING A DISABLED VEHICLE
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use of safety chains is recom-
mended.Attach towing device to main structural mem-
bers of the vehicle Ð not to bumpers or associated
brackets. State and local laws applying to vehicles
under tow must be observed.

394 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM Ð 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 ªMalfunction Indicator Light.º 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!
²Prolonged driving with the ªMalfunction Indica-
tor Lightº 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.
²If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
MAINTAINING YOUR VEHICLE 399

To minimize the possibility of catalytic converter dam-
age:
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 ignition coil connec-
tors disconnected for prolonged periods.
²Do not idle the engine for prolonged periods during
very rough idle or malfunctioning operating condi-
tions.
²Do not allow vehicle to run out of fuel.
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.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.

Automatic Transmission
Fluid Level Check
Your vehicle is equipped with a capped dipstick tube that
is sealed and it should not be tampered with. Your
authorized dealer has the proper tools to ensure that the
fluid level is set properly.
CAUTION!
Using a transmission fluid other than the manufac-
turer's recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than that
recommended by the manufacturer will result in
more frequent fluid and filter changes. Refer to
ªFluids, Lubricants, and Genuine Partsº in this sec-
tion for the correct fluid type.
Fluid and Filter Changes
Change the automatic transmission fluid and filter at the
intervals shown in the ªMaintenance Scheduleº in Sec-
tion 8 of this manual.
In addition, change the fluid and filter if the transmission
is disassembled for any reason.
NOTE:Be sure to follow the ªpolice, taxi, fleet, off-road,
or frequent trailer towingº maintenance interval if appli-
cable.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.

NOTE:Be sure to follow the ªpolice, taxi, fleet, off-road,
or frequent trailer towingº maintenance interval if appli-
cable.
Front/Rear Axle Fluid
Fluid Level Check
The lubricant level should be at bottom edge of the oil fill
hole.
Adding Fluid
Add lubricant only at the fill hole and only to the level
specified above.
Lubricant Selection
Use only manufacturer's recommended lubricant. Refer
to ªFluids, Lubricants, and Genuine Partsº in this section
for the correct fluid type.
Frequency of Fluid Change
Under normal operating conditions, the lubricant in-
stalled at the factory will give satisfactory lubrication forthe life of the vehicle. Lubricant changes are not neces-
sary unless the lubricant becomes contaminated with
water. Change the lubricant immediately if contaminated
with water.
NOTE:Be sure to follow the ªpolice, taxi, fleet, off-road,
or frequent trailer towingº maintenance interval if appli-
cable.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
