When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
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 can turn the system on or off at any time by pressing
the traction control system button located on the console
or on the end of the column shifter. The DIC will display
TRACTION CONTROL OFF when you press the button,
and part of the traction control system is disabled. Your
vehicle will still have brake-traction control, but will not be
able to use the engine speed management system. You
may still hear system noises as a result of the
brake-traction control coming on. If the controller detects
excessive wheel spin in this mode, the traction control
system and StabiliTrak
®
indicator light may blink.
It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if your vehicle is stuck in sand, mud, ice or
snow, and you may want to “rock” your vehicle in an
attempt to free it. See If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-18 for more information.
Adding non-dealer/non-retailer 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 is an advanced computer controlled system that
helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power. The
StabiliTrak
®
system comes on automatically whenever
you start your vehicle. The system cannot be turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system and
StabiliTrak
®
warning light on the instrument panel
cluster will be on after first driving the vehicle and
exceeding 19 mph (30 km/h) for 30 seconds. The
StabiliTrak
®
system is off until the light has turned off.
This could take up to 15 minutes.
The traction control system and StabiliTrak
®
warning light
on the instrument panel cluster will flash when the system
is operating. See Traction Control System (TCS) Warning
Light on page 3-40, StabiliTrak
®
Indicator Light on
page 3-41 and DIC Warnings and Messages on
page 3-56 for more information. You may also feel or
hear the system working. This is normal.
