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 (Except CTS-V)
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 an electronic stability control system
called StabiliTrak. It is an advanced computer controlled
system that assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. StabiliTrak
selectively applies braking pressure at any one of the
vehicle’s brakes to help steer the vehicle in the direction
which you are steering.
When the system activates, the Traction Control
System (TCS)/StabiliTrak warning light on the instrument
panel cluster flashes. You may also hear a noise or feel
vibration in the brake pedal. This is normal. Continue to
steer the vehicle in the direction you want it to go.
If there is a problem detected with StabiliTrak, a
Service Stability System message displays on the
Driver Information Center (DIC) and the TCS/StabiliTrak
warning light on the instrument panel cluster comes on.
When this message and warning light displays, the
system is not operational. Driving should be adjusted
accordingly. See DIC Warnings and Messages on
page 3-57 and Warning Lights, Gages, and Indicators
on page 3-30 for more information.
