AdvanceTrac
Y
Stability Enhancement System (if equipped)
The AdvanceTrac
y
system helps the driver maintain the stability and
steerability of the vehicle. The system integrates anti-lock braking system
(ABS), Traction Control
y
and 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
Control
y
and ABS systems.
The AdvanceTrac
y
constantly 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, AdvanceTrac
y
changes 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 AdvanceTrac
y
enhances stability during maneuvers that require all
available tire traction to control the vehicle. The benefits of the
AdvanceTrac
y
system 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 AdvanceTrac
y
include:
•
Taking a turn too fast
•
Evasively maneuvering to avoid an accident, pedestrian or obstacle
•
Hitting a patch of ice
•
Changing lanes on a snow-rutted road
•
Entering a snow-free road from a snow-covered side street
•
Entering a paved road from a gravel road
•
Hitting a curb while turning
•
Driving on slick surfaces
The AdvanceTrac
y
system defaults to ON when the engine is started.
The system does not work when the vehicle is traveling backwards. In
reverse, ABS and Traction Control
y
will continue to function. The
system uses ABS and Traction Control
y
(including control of the
engine) as well as its more advanced controls to enhance vehicle
stability.
