TRACTION CONTROLY
The Traction Controlysystem helps maintain the stability and steerability of
your vehicle. It is especially useful on slippery and/or hilly road surfaces. The
system operates at all speeds by detecting and controlling wheel spin. The
system borrows many of the electronic and mechanical elements already
present in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controlyportion of the ABS computer. Any excessive wheel
spin is controlled by automatically applying and releasing the rear brakes
in conjunction with engine torque reductions. Engine torque reduction is
realized via the fully electronic spark and fuel injection systems. This
process is very sensitive to driving conditions and very fast acting. The
rear wheels ªsearchº for optimum traction several times a second and
adjustments are made accordingly.
The Traction Controlysystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads. This is especially evident if wheel spin-up should occur
while turning.
During Traction Controlyoperation you may hear an electric motor type
of sound coming from the engine compartment and the engine will not
ªrev-upº when you push further on the accelerator. This is normal
system behavior.
If you should become stuck in snow
or on a very slippery road surface,
try switching the Traction Controly
system off. This may allow excess
wheel spin to ªdigº the vehicle out
or enable a successful ªrockingº
maneuver.
If the Traction Controlysystem is
cycled excessively, the brake portion
of the system will shut down to
prevent the rear brakes from
overheating. A limited Traction Controlyfunction using only engine
torque reduction will still help control wheels from over-spinning. When
the rear brakes have cooled down, the system will again function
normally. Anti-lock braking is not affected by this condition and will
function normally during the cool down period.

AdvanceTracYStability Enhancement System (if equipped)
The AdvanceTracysystem helps the driver maintain the stability and
steerability of the vehicle. The system integrates anti-lock braking system
(ABS), Traction Controlyand a more advanced function to further
enhance the stability of the vehicle. The system shares many of the
electronic and mechanical elements already present in the Traction
Controlyand ABS systems.
The AdvanceTracyconstantly monitors the vehicle motion relative to
the driver's intended course. This is done by using added sensors that
compare the steering inputs from the driver with the actual motion of
the vehicle. When there is a discrepancy between the driver's inputs and
the vehicle motion, AdvanceTracychanges the force at each tire to help
control the vehicle. If the vehicle begins to rotate excessively left or
right, spin out, or slide sideways, the system will attempt to correct the
excessive motion. If the vehicle does not respond to steering inputs, the
system will attempt to increase the turning response of the vehicle.
The AdvanceTracyenhances stability during maneuvers that require all
available tire traction to control the vehicle. The benefits of the
AdvanceTracysystem are most noticeable when driving in wet/snowy/icy
road conditions and/or when performing emergency maneuvers. In an
emergency lane-change, the driver will experience better overall vehicle
traction, and have better control of the vehicle.
Driving conditions which may activate AdvanceTracyinclude:
²Taking a turn too fast
²Evasively maneuvering to avoid an accident, pedestrian or obstacle
²Hitting a patch of ice
²Changing lanes on a snow-rutted road
²Entering a snow-free road from a snow-covered side street
²Entering a paved road from a gravel road
²Hitting a curb while turning
²Driving on slick surfaces
The AdvanceTracysystem defaults to ON when the engine is started.
The system does not work when the vehicle is traveling backwards. In
reverse, ABS and Traction Controlywill continue to function. The
system uses ABS and Traction Controly(including control of the
engine) as well as its more advanced controls to enhance vehicle
stability.

The AdvanceTracyon/off control
button allows the driver to control
the availability of the Traction
Controlyand AdvanceTracy
system. This is independent of the
ABS function, whichCANNOTbe
switched off by the driver. The
AdvanceTracysystem status is
indicated by a warning indicator
light with a ªsliding carº icon in the
instrument cluster that will flash
when the system is active and an indicator light in the control button
that will illuminate when the system is turned OFF. In vehicles with a
message center (if equipped), the message ªADVANCETRAC OFFº is
displayed. If a failure is detected in the AdvanceTracysystem the
warning indicator light in the instrument cluster will stay ON. If the
warning indicator light in the instrument cluster remains ON while the
engine is running, have the system serviced immediately.
The AdvanceTracysystem continually monitors and checks all sensors
used in improving the stability of the vehicle. Some drivers may notice a
slight movement of the brake pedal when the system checks itself.
During AdvanceTracyoperation you may experience the following:
²A rumble or grinding sound much like ABS or Traction Controly
²A slight deceleration or a reduction in the acceleration of the vehicle
²The AdvanceTracyindicator light will flash
²If your foot is on the brake pedal, you will feel a vibration in the pedal
much like ABS. As with any vehicle equipped with four-wheel ABS, do
not pump the brakes, but instead, press firmly on the pedal.
²If the condition is severe and your foot is not on the brake, the brake
pedal will move to apply higher brake forces. You may also hear a
whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTracyoperation.
