StabiliTrak®– Stability Control
System with Traction Control
StabiliTrak combines antilock brake,
traction control, and stability control sys-
tems that help the driver maintain direc-
tional control of the vehicle in most driv-
ing conditions. The system is designed
to help keep the vehicle on the driver’s
intended path by using throttle and
brake intervention.
When activated, the system will apply
braking to individual wheels and may
reduce engine power as necessary to
help you maintain directional control of
the vehicle. You may also hear a noise
or vibration, or feel a reduction in accel-
eration, while the system is active. This
is normal.
StabiliTrak is automatically turned on
when the vehicle is started and does
not require any driver input. It is recom-
mended to leave the system on at all
times for normal driving. It may be
necessary to turn off the traction control
portion of the system if the vehicle is
stuck in sand, mud or snow.
• To turn off the traction control portion
of StabiliTrak, press and release the
(StabiliTrak) button located on
the transmission shift lever. TRAC-
TION CONTROL OFF will be dis-
played on the Driver Information
Center (DIC). Press the button again
to turn the system back on.
• To turn off StabiliTrak, which includes
traction control and stability control
functions, press and hold the
(StabiliTrak) button for five seconds.
STABILITRAK OFF will be displayed
on the DIC. Press the button again
to turn the system back on.
