STABILITY SYS (System) ACTIVE
You may see the STABILITY SYS ACTIVE message on
the DIC. It means that an advanced computer-controlled
system has come on to help your vehicle continue to
go in the direction in which you are steering. StabiliTrak
activates when the 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.
