If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 166.
TCS operates in all transmission shift lever
positions. But the system can upshift the
transmission only as high as the shift lever position
you have chosen, so you should use the lower
gears only when necessary. SeeAutomatic
Transmission Operation on page 124and/or
Manual Transmission Operation on page 126
for more information.
If there is a problem with TCS, TRACTION FAULT
will be displayed on your Driver Information
Center (DIC). SeeDIC Warnings and Messages
on page 202for more information.
When this warning is displayed, the system will not
limit wheel spin. Adjust your driving accordingly.To limit wheel spin, especially in slippery road
conditions, you should always leave TCS on.
But you can turn the system off if you ever need to.
You should turn the system off if your vehicle
ever gets stuck in sand, mud or snow and rocking
the vehicle is required. SeeRocking Your Vehicle
to Get It Out on page 291andIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 290for
more information.
Adding non-GM accessories can affect your
vehicle’s performance. SeeAccessories and
Modi cations on page 324for more information.
Limited-Slip Rear Axle
If your vehicle has this feature, your limited-slip
rear axle can give you additional traction on snow,
mud, ice, sand or gravel. It works like a standard
axle most of the time, but when one of the
rear wheels has no traction and the other does,
this feature will allow the wheel with traction
to move the vehicle.
