The STABILITY SYS ACTIVE message will appear on
the Driver Information Center (DIC) only when the
system is both on and activated. It means that an
advanced computer-controlled system has come on to
help your vehicle continue to go in the direction in which
you're steering. Stabilitrak
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. For more information on the
stability messages, see Driver Information Center (DIC)
on page 3-53.
