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.
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

CAUTION!
Do not allow petroleum base fluid to contaminate
the brake fluid — all brake seal components could
be damaged causing partial or complete brake fail-
ure.
Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses which have unique material charac-
teristics to provide adequate sealing and resist attack by
deteriorated gasoline.
Use only the manufacturers specified hoses in any fuel
system servicing. It is mandatory to replace all clamps
that have been loosened or removed during service. Care
should be taken in installing new clamps to insure they
are properly torqued.
Automatic Transmission
The automatic transmission and differential assembly are
contained within a single housing.
All automatic transmissions are equipped with a conven-
tional filler tube and dipstick. If fluid is added, it should
be added through the dipstick hole in the case.
The dipstick is located just behind the radiator, lower
right side.
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only manufacturers recommended transmis-
sion fluid, refer to 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.
438 MAINTAINING YOUR VEHICLE

CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants and Genuine Parts for correct
fluid type.
Fluid Level Check
The fluid level in the automatic transmission should be
checked whenever the vehicle is serviced. Operation with
an improper fluid level will greatly reduce the life of the
transmission and of the fluid.
To properly check the automatic transmission fluid level,
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. Place the gear selector momentarily in each gear
position ending with the lever in P (PARK). Wipe the area
around the dipstick clean to eliminate the possibility of
dirt entering the transmission.

5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°C), which
is the normal operating temperature after the vehicle has
been driven at least 15 miles (24 km). The fluid cannot be
comfortably held between the finger tips. Cold is when
the fluid is below 80°F (27°C).
6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in the
crosshatched area marked “HOT” (between the upper
two holes in the dipstick).
b. If the fluid is cold, the fluid level should be between
the lower two holes in the area marked “COLD”.
If the fluid level indicates low, add sufficient fluid to
bring to the proper level.CAUTION!
Do not overfill. Dirt and water in the transmission
can cause serious damage. To prevent dirt and water
from entering the transmission after checking or
replenishing fluid, make certain that the dipstick cap
is reseated properly.
Fluid and Filter Changes
Automatic transmission fluid should be changed on all
transmissions as follows:
Normal Usage — No change necessary
Severe Usage (fluid and filter) — Refer to Maintenance
Schedule “B”
Severe Usage is defined as:
