GMC Terrain 2010 Owner's Manual page 251

When the stability control system
activates, the Traction Control
System (TCS)/StabiliTrak light will
flash on the instrument panel. This
also occurs when traction control is
activated. A noise may be heard or
vibration may be felt in the brake
pedal. This is normal. Continue to
steer the vehicle in the intended
direction.
If there is a problem detected with
StabiliTrak, a Service StabiliTrak
message will be displayed on the
Driver Information Center (DIC).
When this message is displayed
and the StabiliTrak light comes on,
the system is not operational.
Driving should be adjusted
accordingly. See Ride Control
System Messages on page 4 33.
StabiliTrak comes on automatically
whenever the vehicle is started. To
assist with directional control of the
vehicle, the system should always
be left on.
Driving and Operating
StabiliTrak can be turned off by
pressing and holding the TCS/
StabiliTrak button, on the console,
until the TCS Off and StabiliTrak Off
lights come on the instrument panel
and StabiliTrak Off appears in the
DIC. For information on turning TCS
off and on, see Traction Control
System (TCS) earlier in this
section.
If cruise control is being used when
StabiliTrak activates, the cruise
control will automatically disengage.
Press the cruise control button to
reengage when road conditions
allow. See Cruise Control on
page 8 44 for more information.
