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” (MIL). 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 authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL 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 MIL is flashing while the engine is running,
severe catalytic converter 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 possibly loose or
improperly installed. A “gASCAP” message will be dis-
played in the instrument cluster. Tighten the gas cap until
aclicking sound is heard. This is an indication that the
gas cap is properly tightened. Press the trip odometer
RESET button to turn off the message. If the problem

CAUTION!
•Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealer or qualified
repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at regular
intervals, such as every fuel stop. The best time to check the
engine oil level is about five minutes after a fully warmed
engine is shut off. Do not check oil level before starting the
engine after it has sat overnight. Checking engine oil level
when the engine is cold will give you an incorrect reading.
Checking the oil while the vehicle is on level ground and
only when the engine is hot, will improve the accuracy of
the oil level readings. Maintain the oil level between the
range markings on the dipstick. The range markings will
consist of a crosshatch zone which depicts the MIN at the
low end of the range and MAX at the high end of the range.
Adding 1 qt (1L) of oil when the reading is at the low end
of the indicated range will result in the oil level at the full
end of the indicator range.

Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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, or for prolonged periods during very rough
idle or malfunctioning operating conditions.

WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. Fluid level can be expected to fall as thebrake pads wear. The brake fluid level should be checked
when the pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
NOTE:
If your vehicle is equipped with a manual trans-
mission, the brake fluid reservoir supplies fluid to both
the brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transmission clutch release system should not require
fluid replacement during the life of the vehicle. If the
brake fluid reservoir is low and the brake system does
not indicate any leaks or other problems, it may be a
result of a leak in the hydraulic clutch release system. See
your local authorized dealer for service.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.

CAUTION!
Use of improper brake fluids will affect overall clutch
system performance. Improper brake fluids may dam-
age the clutch system resulting in loss of clutch func-
tion and the ability to shift the transmission.
Automatic Transmission — If Equipped
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in this
section for fluid specifications. It is important to maintain
the transmission fluid at the correct 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 will require more
frequent fluid and filter changes. Refer to “Fluids,
Lubricants, and Genuine Parts” in this section for
fluid specifications.
No chemical flushes should be used in any transmission;
only the approved lubricant should be used.

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
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 for diagnosing fluid
leaks. Avoid using transmission sealers as they may
adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Routine fluid level checks are not required, therefore the
transmission has no dipstick. Your authorized dealer can
check your transmission fluid level using special service
tools. If you notice fluid leakage or transmission malfunc-
tion, visit your authorized dealer immediately to have
the fluid level checked. Operating the vehicle with an
improper fluid level can cause severe transmission dam-
age.
CAUTION!
If a transmission fluid leak occurs, visit your autho-
rized dealer immediately. Severe transmission dam-
age may occur. Your authorized dealer has the proper
tools to adjust the fluid level accurately.

Fluid and Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the
life of the vehicle. However, if the vehicle is used for
frequent trailer towing, police, fleet, taxi, etc., change the
fluid as indicated in the Maintenance Schedule. In addi-
tion, change the fluid (and filter, if equipped) if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
Manual Transmission — If Equipped
Lubricant Selection
Use only the manufacturers recommended transmission
fluid. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Fluid Level Check
The transmission is designed to be fill for life. The oil
does not need to be check unless there is an oil leak.
Should the transmission be leaking oil, the transmission
should be serviced to correct the condition.
Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless lubri-
cant has become contaminated with water.
NOTE:If contaminated with water, the fluid should be
changed immediately.
