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.
STABILITY SYS (System) DISABLED
The STABILITY SYS DISABLED message will turn on
when you press the StabiliTrak
®
button, or when
the stability control has been automatically disabled.
To limit wheel spin and realize the full benefits of
the stability enhancement system, you should normally
leave StabiliTrak
®
on. However, you should turn
StabiliTrak
®
off if your vehicle gets stuck in sand, mud,
ice, or snow and you want to rock your vehicle to
attempt to free it, or if you are driving in extreme off-road
conditions and require more wheel spin. See If Your
Vehicle is Stuck in Sand, Mud, Ice or Snow on
page 4-46. To turn the StabiliTrak
®
system back on,
press the StabiliTrak
®
button again.
There are several conditions that can cause this
message to appear.
• One condition is overheating, which could occur if
StabiliTrak
®
activates continuously for an extended
period of time.
• The message will also be displayed if the brake
system warning light is on. See Brake System
Warning Light on page 3-41.
• The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
• If an engine or vehicle related problem has been
detected and the vehicle needs service, the
message will appear. See your GM dealer.
• The message will also appear if the vehicle is
shifted into 4LO.
The message will turn off as soon as the conditions that
caused the message to be displayed are no longer
present.
