Brake Assist; Braking In Emergencies; Stabilitrak System - Pontiac Torrent 2009 Owner's Manual

Braking in Emergencies

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

Brake Assist

This vehicle has a Brake Assist feature designed to
assist the driver in stopping or decreasing vehicle speed
in emergency driving conditions. This feature uses the
stability system hydraulic brake control module to
supplement the power brake system under conditions
where the driver has quickly and forcefully applied the
brake pedal in an attempt to quickly stop or slow down
the vehicle. The stability system hydraulic brake control
module increases brake pressure at each corner of the
vehicle until the ABS activates. Minor brake pedal
pulsations or pedal movement during this time is normal
and the driver should continue to apply the brake pedal
as the driving situation dictates The Brake Assist feature
will automatically disengage when the brake pedal is
released or brake pedal pressure is quickly decreased.

StabiliTrak System
The vehicle has the StabiliTrak system, an advanced
computer controlled system that helps the driver
maintain directional control of the vehicle in difficult
driving conditions. This is accomplished by selectively
applying any one of the vehicle's brakes and reducing
power. The Stabilitrak system comes on automatically
whenever the vehicle is started.
The STABILITRAK NOT READY message may be
displayed in the Driver Information Center (DIC) and
the StabiliTrak/Traction Control System (TCS) warning
light will come on the instrument panel cluster after first
driving the vehicle and exceeding 30 mph 48 (km/h) for
30 seconds. The StabiliTrak system is off until the light
has turned off. This could take up to 15 minutes. See
DIC Warnings and Messages on page 3-50 for more
information.
The StabiliTrak/TCS
warning light on the
instrument panel cluster
will flash when the system
is operating.
