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 Indicator
Light” on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
•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.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
cap until aclickingsound is heard. This is an indication

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 damage:
•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 conditions.
•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.

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 pro-
longed braking. You could have an accident.
WARNING!
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.

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 – 3.7L Gasoline Engine (42RLE)
and 2.8L Diesel Engine (545RFE)
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 into 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 recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks.
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.
