Pontiac 2004 Grand Prix - Manual (Page 249)

Stabilitrak ® Plus System
Your vehicle may be equipped with a vehicle stability
enhancement system called Stabilitrak
® Plus. It is
an advanced computer controlled system that assists
you with directional control of the vehicle in difficult
driving conditions.
Stabilitrak ® Plus comes on whenever the vehicle is
started. It activates when the computer senses a
discrepancy between your intended path and the
direction the vehicle is actually traveling. Stabilitrak
®
Plus selectively applies braking pressure at any one of
the vehicle’s brakes to help steer the vehicle in the
direction which you are steering.
This symbol, along with
the STABILITY CONTROL
ACTIVE message will
appear on the Driver
Information Center (DIC).
See DIC Warnings and Messages on page 3-65 .
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
®
Plus, this symbol along
with the SERVICE
STABILITY SYSTEM
warning message will be
displayed on the Driver
Information Center (DIC).
See DIC Warnings and Messages on page 3-65 . When
this message is displayed, the system is not operational.
Driving should be adjusted accordingly.
If your vehicle is in cruise control when Stabilitrak ® Plus
activates, the cruise control will automatically disengage.
When road conditions allow you to safely use it again,
you may reengage the cruise control. See
Cruise Control
Lever on page 3-8 for more information.
