The system may be heard or felt while it is working, but
this is normal. See Traction Control System (TCS)
Warning Light on page 4 38 for more information.
If the vehicle is in cruise control when TCS begins to
limit wheel spin, the cruise control will automatically
disengage. The cruise control may be re-engaged when
road conditions allow. See Cruise Control on page 4 9.
The SERVICE TRACTION CONTROL message in the
DIC and the TCS/StabiliTrak warning light comes on if
there is a problem with the traction control system. See
DIC Warnings and Messages on page 4 55.
When this light and the SERVICE TRACTION
CONTROL message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The TCS and StabiliTrak
light will flash when the
system is limiting
wheel spin.
®
TCS automatically comes on whenever the vehicle is
started. To limit wheel spin, especially in slippery road
conditions, always leave the system turned on. TCS
can be turned off if needed.
The system can be turned on or off at any time by
pressing the TCS button. The DIC will display
TRACTION CONTROL OFF when the button is
pressed, and part of the traction control system is
disabled. The vehicle will still have brake-traction
control, but will not be able to use the engine speed
management system. System noises may be heard as
a result of the brake-traction control working. If the
controller detects excessive wheel spin in this mode,
the TCS/StabiliTrak light may blink.
To turn the system off or
on, press and release this
button located in front of
the shift lever.
