rized dealer service center as soon as possible.
ELECTRONIC BRAKE CONTROL SYSTEMS
Your vehicle is equipped with an advanced electronic
brake control system that includes TCS (Traction Control
System), BAS (Brake Assist System) and ESP (Electronic
Stability Program). These systems complement the Anti-
Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneu-
vers.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle isspinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if the ESP is in the
ªPartial Offº mode.
The Traction Control System (TCS) Indicator
Light, located in the instrument cluster, starts
to flash as soon as the tires lose traction and the
wheels begin to spin. This indicates that the
TCS is active. If the indicator light flashes during accel-
eration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions, and do not
switch off the ESP or TCS.
340 STARTING AND OPERATING

Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be replaced.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 in (2 mm). When the tread is worn to the
tread wear indicators, the tire should be replaced.Many states have laws requiring tire replacement at this
point.
Tire Life
The service life of a tire is dependent upon varying
factors including but not limited to:
²Driving style
²Tire pressure
²Distance driven
WARNING!
Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.
364 STARTING AND OPERATING

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Please see ªTread Wear
Indicatorsº and ªTire and Loading Informationº placard
for the size designation of your tire in this section. The
service description and load identification will be found
on the original equipment tire. Failure to use equivalent
replacement tires may adversely affect the safety, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment manufacturer or an
authorized tire dealer with any questions you may have
on tire specifications or capability.
WARNING!
DO NOT use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for 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 authorized dealer for service as
soon as possible.CAUTION!
²Prolonged driving with the ªMalfunction Indica-
tor 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 per-
formed.
²If the ªMalfunction Indicator Lightº 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 Ð gASCAP
Should the ªLoose Fuel Filler Capº or ªgASCAPº mes-
sage appear, there may be a problem in the evaporative
system. Before taking the vehicle into an authorized
dealer, check first to see if the fuel filler cap is possibly
loose, improperly installed, or damaged. A loose fuel
filler cap message will be displayed in the instrument
cluster. Tighten the gas cap until a9clicking9sound is
heard. This is an indication that the gas cap is properly
tightened. Press the odometer reset button to turn the
message off. If the problem persists, the message will
appear the next time the vehicle is started. If the problem
is detected twice in a row, the system will turn on the
Malfunction Indicator Light (MIL). Resolving the prob-
lem will turn the MIL light off. Take your vehicle in to an
authorized dealer.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of this vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the Malfunction
Indicator Light (MIL) is functioning and is not on
when the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if the vehicle was recently
serviced, recently had a dead battery, or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, the vehicle may fail the test.
438 MAINTAINING YOUR VEHICLE

EMISSIONS CONTROL SYSTEM MAINTENANCE
The Scheduled Maintenance services listed inbold type,
must be done at the times or mileages specified to ensure
the continued proper functioning of the Emissions Con-
trol System. These, and all other maintenance services
included in this manual, should be done to provide best
vehicle performance and reliability. More frequent main-
tenance may be needed for vehicles in severe operating
conditions, such as dusty areas and very short trip
driving.
Inspection and service should also be done anytime a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sions control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part that has been
certified pursuant to U.S. EPA or in the State of Califor-
nia, California Air Resources Board regulations.
MAINTENANCE SCHEDULE
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
On Non-EVIC equipped vehiclesCHAngE OILwill flash
in the instrument cluster odometer and a single chime
will sound, indicating that an oil change is necessary.
On Electronic Vehicle Information Center (EVIC)
equipped vehiclesOil Change Requiredwill be dis-
played in the EVIC and a single chime will sound,
indicating that an oil change is necessary.
Based on engine operation conditions the oil change
indicator message will illuminate, this means that service
is required for your vehicle. Have your vehicle serviced
as soon as possible, within the next 500 mi (805 km).
