You may feel or hear the system working, but this is
normal. Leave the system on during ordinary driving so
that it can operate when needed. When the ignition
is turned to ON, the system automatically turns on.
This light should come on
briefly when you start the
engine. If it stays on or
comes on while you
are driving, there is a
problem with your traction
control system.
The TRAC OFF button is
located to the left of the
steering wheel below
the instrument panel
cluster.
When getting the vehicle out of mud or newly fallen
snow, turn off the traction control system. The system
that controls engine performance interferes with the
process of freeing the front wheels. To turn off traction
control, press the TRAC OFF button. The traction
control system warning light will come on. The vehicle
stability control system (StabiliTrak
®
) is always activated,
even when the traction control system is turned off.
To turn the traction control system back on, press the
TRAC OFF button again. The traction control system
warning light will go off. See Traction Control System
(TCS) Warning Light on page 3-34 for more information.
Adding non-GM accessories can affect your vehicle’s
performance. See Accessories and Modifications
on page 5-3 for more information.
StabiliTrak
®
System
Your vehicle may have this feature. The StabiliTrak
®
system helps provide integrated control of the systems
such as anti-lock brake system, traction control and
engine control. This system automatically controls the
brakes and engine to help prevent the vehicle from
skidding when cornering on a slippery road surface or
turning the steering wheel abruptly.
