To limit wheel spin, especially in slippery road
conditions, you should always leave the Traction
Control System on. But you can turn the system off
if you prefer.
To turn the system on or off, press the TC button
located under the climate controls. In order to
effectively “rock” the vehicle, you will need to turn
off TCS.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. Press the TC button
again to turn the system back on. The traction
control system warning light will go off.
When you turn the system off, the Traction Control
System warning light will come on and stay on.
If the Traction Control System is limiting wheel spin
when you press the button to turn the system
off, the warning light will come on – but the system
won’t turn off right away. It will wait until there’s
no longer a current need to limit wheel spin.
Adding non-GM accessories can affect your
vehicle’s performance. See Accessories and
Modifications on page 342 for more information.
Enhanced Traction System (ETS)
Your vehicle may have an Enhanced Traction
System (ETS) that limits wheel spin. This is
especially useful in slippery road conditions.
The system operates only if it senses that one or
both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system reduces engine power and may also
upshift the transaxle to limit wheel spin.
This light will come on
when your Enhanced
Traction System is
engaged and limiting
wheel spin.
You may feel or hear the system working, but this
is normal.
If your vehicle is in cruise control when the
Enhanced Traction 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. See Cruise Control on page 176.
