Braking In Emergencies; Stabilitrak System - GMC Yukon Denali 2006 Manual

Braking in Emergencies

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

StabiliTrak System
Your vehicle is equipped with StabiliTrak
combines antilock brake, traction and stability control
systems and helps the driver maintain directional control
of the vehicle in most driving conditions.
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. The system
should initialize before the vehicle reaches 20 mph
(32 km/h). In some cases, it may take approximately
two miles of driving before the system initializes.
If the system fails to turn on or activate, the STABILITY
SYS DISABLED or SERVICE STABILITY message
will be displayed. If the vehicle has gone through heavy
acceleration or braking or multiple turns during the
first two miles of driving after starting your vehicle, the
STABILITY SYS DISABLED message may appear.
If this is the case, your vehicle does not need servicing.
You will need to turn the vehicle off and then restart
it to initialize StabiliTrak
the Driver Information Center (DIC), and your vehicle
hasn't gone through hard acceleration, braking or
multiple turns in the first two miles of driving, your
vehicle should be taken in for service.
The STABILITY SYS ACTIVE message will appear on

, which
the Driver Information Center (DIC) only when the
system is both on and activated. It means that an
advanced computer-controlled system has come on to
help your vehicle continue to go in the direction in which
you're steering. StabiliTrak
computer senses that your vehicle is just starting to
spin, as it might if you hit a patch of ice or other slippery
spot on the road. When the system activates, you
may hear a noise or feel a vibration in the brake pedal.
This is normal. When the STABILITY SYS ACTIVE
message is on, you should continue to steer in
the direction you want to go. The system is designed to
help you in bad weather or other difficult driving
situations by making the most of whatever road
conditions will permit. For more information on the
stability messages, see Driver Information Center (DIC)
on page 3-46.
