Braking In Emergencies; Locking Rear Axle; Stabilitrak System - GMC 2006 Envoy Owner's Manual

Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply your
brakes if that vehicle suddenly slows or stops. Always
leave enough room up ahead to stop, even though
you have ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down firmly and let anti-lock work for you. You may feel
the brakes vibrate, or you may notice some noise,
but this is normal.

Braking in Emergencies

With ABS, you can steer and brake at the same time. In
many emergencies, steering can help you more than
even the very best braking.

Locking Rear Axle

If your vehicle has this feature, your locking rear axle
can give you additional traction on snow, mud, ice, sand
or gravel. It works like a standard axle most of the
time, but when one of the rear wheels has no traction
and the other does, this feature will allow the wheel with
traction to move the vehicle.

StabiliTrak System
Your vehicle is equipped with StabiliTrak
Stability Control (ESC) which combines antilock
brake, traction and stability control systems and helps
the driver maintain directional control of the vehicle
in most driving conditions.
Traction control activates when the controller senses
®
wheel spin. StabiliTrak
and reduce engine torque to help regain traction.
Stability control activates when the controller senses a
discrepancy between your intended path and the
direction the vehicle is travelling. StabiliTrak
applies braking pressure at any one of the vehicle's
brakes to help guide the vehicle in the direction which
you are steering.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic checks to
insure there are no problems. You may hear or feel
the system working. This is normal and does not mean
there is a problem with your vehicle. If driving
conditions delay system initialization, the STABILITRAK
NOT READY message may be displayed. If this is
the case, your vehicle does not need servicing.
For more information on the stability messages, see
DIC Warnings and Messages on page 3-54.
