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 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 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
odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.

CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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 indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine off, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer's
specifications immediately.
To minimize the possibility of catalyst damage:
²Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.

CAUTION!
Do not allow petroleum base fluid to contaminate
the brake fluid, all brake seal components could be
damaged causing partial or complete brake failure.
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 manufac-
turer 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 does not
require adjustment under normal operating con-
ditions. If a transmission fluid leak occurs, visit
your authorized dealer immediately. Severe dam-
age to the transmission may occur. Your autho-
rized dealer has the proper tools to adjust the
fluid level accurately.
Fluid and Filter Changes
Automatic transmission fluid and filter should be
changed as follows:
Normal Usage Ð No change necessary
286 MAINTAINING YOUR VEHICLE
Page 287 of 350

Severe Usage (fluid and filter) Ð Refer to Maintenance
Schedule ªBº
Severe Usage is defined as:
²Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is drivenregularlyfor
more than 45 minutes of continuous operation.
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.
Front And Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
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 chemicals 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 contami-
nants, road surfaces on which the vehicle is operated,
extreme hot or cold weather and other extreme condi-
tions will have an adverse effect on paint, metal trim, and
underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
²Road salt, dirt, and moisture accumulation.
