Traction Control System (TCS)
Your vehicle may have a traction control system 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 to limit wheel spin.
This light will come on
when your traction control
system is limiting wheel
spin. You may feel or hear
the system working, but
this is normal.
The traction control system automatically comes 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 traction
control system off if you ever need to. You should turn
the system off if your vehicle ever gets stuck in
sand, mud, ice or snow and rocking the vehicle is
required. See Rocking Your Vehicle to Get It Out on
The traction control system
can be turned off by
pressing the traction
control button, located on
the instrument panel
above the audio system.
The traction control system can be activated again by
pressing the traction control button.
If the system is limiting wheel spin when you press the
button, the traction control off light will appear on
the instrument panel cluster. The system will not turn off
until there is no longer a current need to limit wheel
spin. You can turn the system back on at any time by
pressing the button again. If the light does not come on,
you may not have traction control and your vehicle
should be serviced by a dealer.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modiﬁcations
on page 5-3 for more information.
