If you should become stuck in snow
or on a very slippery road surface,
try switching the Traction Control娂
system off. This may allow excess
wheel spin to “dig” the vehicle out
or enable a successful “rocking”
maneuver.
If the Traction Control娂 system is
cycled excessively, the brake portion
of the system will shut down to
prevent the rear brakes from
overheating. A limited Traction Control娂 function 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.
AdvanceTrac姟 Stability Enhancement System (if equipped)
The AdvanceTrac娂 system helps the driver maintain the stability and
steerability of the vehicle. The system integrates anti-lock braking system
(ABS), Traction Control娂 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娂 and ABS systems.
The AdvanceTrac娂 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娂 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娂 enhances stability during maneuvers that require all
available tire traction to control the vehicle. The benefits of the
AdvanceTrac娂 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.
