Buick 2009 Enclave - Manual (Page 243)

For vehicles with the 5.3L V8 engine, StabiliTrak can be
turned off by pressing and holding the traction control
button, located above the radio, for approximately
five seconds. A STABILITY CONTROL OFF message
will be displayed on the DIC when StabiliTrak is
turned off. StabiliTrak will remain off until the traction
control button is pressed once to turn it back on, or until
the engine is restarted.
Traction Control System (TCS)
The vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are
spinning or beginning to lose traction. When this
happens, the system works the front brakes and reduces
engine power to limit wheel spin. It may also upshift
the transmission to limit wheel spin. The system may be
heard or felt while it is working, but this is normal.
The TRACTION CONTROL ACTIVE message on the
Driver Information Center (DIC) will be displayed
when the system is limiting wheel spin.
If cruise control is being used when TCS begins to limit
wheel spin, the cruise control automatically disengages.
The cruise control can be re-engaged when road
conditions allow. See Cruise Control on page 3-10.
TCS operates in all transmission shift lever positions.
But the system can upshift the transmission only as high
as the shift lever position that was chosen, so use the
lower gears only when necessary. See Automatic
Transmission Operation on page 2-26.
