Stabilitrak System - Hummer 2007 H3 Owner's Manual

®
StabiliTrak System
Your vehicle has a vehicle stability enhancement
system called StabiliTrak
computer controlled system that assists you 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 assist the driver
with keeping the vehicle on the intended path.
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 there is a problem detected with StabiliTrak
a SERVICE STAB SYS message will be displayed
on the Driver Information Center (DIC). See
DIC Warnings and Messages on page 196 for
more information. When this message is displayed,
the system is not operational. Adjust your driving
accordingly.
