Hummer 2007 H3 - Manual (Page 242)

If your vehicle has a Driver information Center
(DIC), a TRACTION FAILED message will appear
when a Traction Control System or Anti-Lock
Brake System problem has been detected and the
vehicle needs service. See DIC Warnings and
Messages on page 196 for more information.
When this message is 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.
To turn the system off,
press and hold the TCS
button for five seconds.
This light will come
on steady when the
traction control system
has been turned off.
This light flashes
when TCS is active.
If you press and hold the TC button for
five seconds, the traction control system will turn
off and a TRAC OFF message will appear on
the DIC. Press the TC button again to turn
the system back on. The TRAC OFF message
will then go off. The traction control system
will reset itself at each ignition cycle.
Adding non-GM accessories can affect your
vehicle’s performance. See Accessories and
Modifications on page 314 for more information.
