Traction Control Operation - Chevrolet 2004 Express Van Owner's Manual

Traction Control Operation

The traction control system is part of the
®
Stabilitrak system. Traction control limits wheel spin by
reducing engine power to the wheels (engine speed
management) and by applying brakes to each individual
wheel (brake-traction control) as necessary.
Notice: Allowing the wheel of one axle to spin
excessively while the STABILITRAK NOT READY
light is on due to heavy braking and/or because the
traction control system has been continuously
active, may cause damage to the transfer case. This
could lead to costly repairs not covered by your
warranty. Do not allow the wheel of one axle to spin
excessively while the STABILITRAK NOT READY
light is on.
If the brake-traction control system activates constantly
or if the brakes have heated up due to high speed
braking, the brake-traction control will be automatically
disabled. The system will come back on after the
brakes have cooled. This can take up to two minutes or
longer depending on brake usage.

Notice: If you allow the wheel(s) of one axle to spin
excessively while the traction off, ABS,
STABILITRAK NOT READY and brake warning lights
are displayed, you could damage the transfer
case. The repairs would not be covered by your
warranty. Reduce engine power and do not spin the
wheel(s) excessively while these lights are
displayed.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens you may
notice a reduction in acceleration, or may hear a noise
or vibration. This is normal.
If your vehicle is in cruise control when the system
®
activates, a Stabilitrak indicator light will appear on the
instrument panel and the cruise control will automatically
disengage. When road conditions allow you to use
cruise again, you may re-engage the cruise control. See
"Cruise Control" under Turn Signal/Multifunction Lever
on page 3-8
®
Stabilitrak may also turn off automatically if it
determines that a problem exists with the system. If the
problem does not clear itself after restarting the
vehicle, you should see your dealer for service.
