Automatic Transfer Case
If your vehicle has four-wheel drive, the transfer
case knob is located to the right of the steering
wheel on the instrument panel.
Use this knob to shift
into and out of
four-wheel drive
2
m(Two-Wheel High):This setting is for
driving in most street and highway situations.
Your front axle is not engaged in two-wheel drive.
It also provides the best fuel economy.AUTO (Automatic Four-Wheel Drive):This
setting is ideal for use when road conditions are
variable. When driving your vehicle in automatic
four-wheel drive, the front axle is engaged, but the
vehicle’s power is sent to the rear wheels.
When the vehicle senses a loss of traction, the
system will automatically engage four-wheel drive.
Driving in this mode results in slightly lower fuel
economy than Two-Wheel High.
4
m(Four-Wheel High):This setting should be
used when you need extra traction, such as
on snowy or icy roads or in most off-road
situations. This setting also engages your front
axle to help drive your vehicle.
4
n(Four-Wheel Low):This setting also
engages your front axle and delivers extra torque.
It sends maximum power to all four wheels.
You might choose this setting if you are driving
off-road in deep sand, deep mud, and climbing or
descending steep hills.

StabiliTrak®will turn off automatically if a problem is
detected in the system. The StabiliTrak®light will
come on and SERVICE STABILITRAK will be
displayed on the DIC. For vehicles without a DIC,
the StabiliTrak
®light and the StabiliTrak®service
light will both come on. 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. SeeAccessories and
Modi cations on page 386for more information.
All-Wheel Drive (AWD) System
(TrailBlazer SS)
If your vehicle has this feature, engine power is
sent to all four wheels all the time.
This is like four-wheel drive, but there is no
separate lever or switch to engage or disengage
the front axle. It is fully automatic, and adjusts itself
as needed for road conditions.
Steering
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 the 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.
