The traction off light will come on under the following
conditions:
• The Traction Assist System is turned off, either by
pressing the TAS on/off button, located on the
instrument panel, or by turning off the automatic
engagement feature of the TAS.
• The transmission is in FIRST (1); TAS will not
operate in this gear. This is normal.
• The vehicle is driven on an extremely rough road.
When the vehicle leaves the rough surface, slows
down or stops, the light will go off and TAS will turn
on again. This is normal.
• A Traction Assist System, Anti-Lock Brake System
or engine-related problem has been detected and
the vehicle needs service.
• If the vehicle has been driven with the TAS system
on for long periods of time, or if the vehicle has
gone through many several high speed braking
maneuvers the system may be automatically
disabled. The system will automatically re-enable
after approximately two minutes of not using
the brakes.
See Traction Off Light on page 3-42.
The Traction Assist System, as delivered from the
factory, will automatically come on whenever you start
your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the TAS off if you ever need
to. You should turn the TAS off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required. See Rocking Your Vehicle to Get It Out
on page 4-46 and If Your Vehicle is Stuck in Sand, Mud,
Ice or Snow on page 4-46.
To turn the system on or
off, press the TAS on/off
button located on the
instrument panel.
If you used the button to turn the system off, the traction
off light will come on and stay on. You can turn the
system back on at any time by pressing the button
again. The traction off light should go off.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-4 for more information.
