StabiliTrak – Stability Control
®
System
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 nec-
essary to turn off the system if the vehi-
cle is stuck in sand, mud or snow.
To turn off StabiliTrak, press and hold
the (StabiliTrak) button on the trans-
mission shift handle for five seconds.
STABILITRAK OFF will be displayed on
the DIC. Press the button again to turn
the system back on.
See Section 4 of your Owner Manual.
