382 MAINTAINING YOUR VEHICLE

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!
Prolonged driving with the ªMalfunction Indicator
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 performed.
If the ªMalfunction Indicator Lightº is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur. Im-
mediate service is required.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð if equipped. If this
occurs, tighten the fuel filler cap properly and press the

CAUTION!
Do not allow petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.
Automatic Transmission
Fluid Level Check
Regular automatic transmission fluid level checks are not
required. For this reason, the dipstick is omitted.
If you notice fluid loss or gear shift malfunction, have
your authorized dealer check the transmission fluid level.
CAUTION!
²Using a transmission fluid other than the manu-
facturer's recommended fluid may cause deterio-
ration 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 Genu-
ine Partsº for the correct fluid type.
²The fluid level is preset at the factory and it does
not require adjustment under normal operating
conditions. If a transmission fluid leak occurs,
visit your authorized dealer immediately. Severe
damage to the transmission may occur. Your au-
thorized dealer has the proper tools to adjust the
fluid level accurately.
414 MAINTAINING YOUR VEHICLE

Fluid and Filter Changes
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for the recommended transmission fluid and
filter change intervals.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
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.
All Wheel Drive (AWD) Ð If Equipped
The all wheel drive system consists of a Transfer Case
and Front Differential. The exterior surface of these
components should be inspected for evidence of fluid
leaks. Confirmed leaks should be repaired as soon as
possible.
The transfer case fluid inspection plug is located in the
middle of the rear housing. To inspect the transfer case
fluid level, remove the inspection plug. The fluid level
should be even with the bottom of the hole. The transfer
case fill plug is located on the rear housing near the
output shaft.
The front differential fill plug is located on the outer
cover near the halfshaft attachment. To inspect the differ-
ential fluid level, remove the fill plug. The fluid level
should be even with or slightly below the bottom of the
hole.
