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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check fuel cap” message will be displayed in the
Electronic Vehicle Information Center (EVIC). Refer to
330 MAINTAINING YOUR VEHICLE
Page 336 of 425

Besides those maintenance items specified in the fixed
“Maintenance Schedule”, there are other components
which may require servicing or replacement in the future.
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.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the
334 MAINTAINING YOUR VEHICLE

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.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
• Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.

WARNING!(Continued)
cylinder reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission (3.6L Gasoline Engine
Only)
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. No chemical flushes should be used
in any transmission; only the approved lubricant should
be used.
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, and will require more frequent fluid and
filter changes. Refer to “Fluids, Lubricants, And
Genuine Parts” in this section for fluid specifica-
tions.
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 filler tube is capped and no dipstick is
provided. Your authorized dealer can check your trans-
mission fluid level using a special service dipstick. If you
notice fluid leakage or transmission malfunction, visit
your authorized dealer immediately to have the trans-
mission fluid level checked. Operating the vehicle with
an improper fluid level can cause severe transmission
damage.
354 MAINTAINING YOUR VEHICLE

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
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
In addition, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the trans-
mission is disassembled for any reason.
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 roadspassable in snow and ice and those 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 contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body 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:
•
Road salt, dirt and moisture accumulation.
• Stone and gravel impact.
