If the SERVICE STABILITRAK message (or StabiliTrak
service light) does not clear itself after restarting the
vehicle, you should see your dealer for service.
Adding non-GM accessories can affect your vehicle's
performance. See Accessories and Modifications
on page 5-3 for more information.
All-Wheel Drive (AWD) System
Your vehicle may have this feature. There is no lever
or switch to engage or disengage the front axle. It is fully
automatic and adjusts as needed for road conditions.
Your vehicle has an active transfer case allowing
two-wheel-drive operation on dry roads. The transfer
case will shift automatically into all-wheel drive on
slippery surfaces. You may feel an extra shift when
the all-wheel drive engages.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer
but it will take much more effort.

Steering Tips
It is important to take curves at a reasonable speed.
A lot of the "driver lost control" accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is subject
to the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels. If there is no traction, inertia
will keep the vehicle going in the same direction. If
you have ever tried to steer a vehicle on wet ice, you
will understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle
at which the curve is banked, and your speed. While you
are in a curve, speed is the one factor you can control.
Suppose you are steering through a sharp curve.
Then you suddenly accelerate. Both control
systems — steering and acceleration — have to do
their work where the tires meet the road. Adding
the sudden acceleration can demand too much of
those places. You can lose control.
