JUMP STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin, or
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-
ing with batteries. Do not use a booster battery or
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:Set the parking brake, place an automatic transmission in
P (Park) (or N (Neutral) for a manual transmission). Turn
off lights, heater, and other electrical loads. Observe
charge indicator in the battery. If indicator is light or
yellow, replace the battery.
CAUTION!
Use the “Jump Starting” procedure only when the
charge indicator is dark in the center. Do not attempt
jump starting when the battery charge indicator is
bright or yellow. If the charge indicator is dark and
has a green dot in the center, failure to start is not
due to a discharged battery and the cranking system
should be checked.

246 MAINTAINING YOUR VEHICLE

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.
250 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 into contact with your ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturer’s specifica-
tions, should be obtained immediately.
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 condi-
tions.
•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.

should be checked when pads are replaced. However,
low fluid level may be caused by a leak and a checkup
may be needed.
Use only manufacturer’s recommended brake fluid, refer
to Recommended Fluids, Lubricants, and Genuine Parts
for correct fluid type.
WARNING!
•Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter. Do
not allow petroleum base fluid to contaminate the brake
fluid as seal damage will result.
Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturer’s recommended transmis-
sion fluid, refer to Recommended Fluids, Lubricants, and
Genuine Parts for correct fluid type. It is important that
the transmission fluid be maintained at the prescribed
level using the recommended fluid.
274 MAINTAINING YOUR VEHICLE

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 the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
Recommended Fluids, Lubricants, and Genuine
Parts for correct fluid type.
Fluid Level Check — 42RLE
This fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is
heated to its normal operating temperature. Operation of
the transmission with an improper fluid level will greatly
reduce the life of the transmission and of the fluid.To check the automatic transmission fluid level properly,
the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Apply the brakes and shift the transmission momen-
tarily into each gear position ending in P (Park).
5. The fluidMUSTbe checked with the transmission in
P (Park) to be sure that the fluid level is accurate.
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
At normal operating temperature (approximately 180° F
(82° C), the fluid level is correct if it is in the HOT region

(cross-hatched area) on the oil level indicator. The fluid
level indicator should be in the COLD region at 70° F (21°
C) fluid temperature.
If the fluid level is low, add sufficient fluid to bring to the
proper level. Refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type.
Fluid is added through the dipstick tube.
NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated.
Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. The only
exception to this policy is the use of special dyes to aid in
detecting fluid leaks. The use of transmission sealers
should be avoided as they may adversely affect seals.
Hydraulic Clutch Fluid — Manual Transmission
The clutch hydraulic system is a sealed maintenance free
system. In the event of leakage or other malfunction, the
system must be replaced.
Manual Transmission
Selection of Lubricant
Use only manufacturer’s recommended manual trans-
mission fluid, refer to Recommended Fluids, Lubricants,
and Genuine Parts for correct fluid type.
Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16” (4.76 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
