Stabilitrak ® System - GMC 2007 Yukon XL Owner's Manual

®
StabiliTrak System
Your vehicle may be equipped with the
®
StabiliTrak system which combines antilock
brake, traction and stability control systems and
helps the driver maintain directional control of the
vehicle in most driving conditions.
When you first start your vehicle and begin to drive
away, the system performs several diagnostic
checks to ensure 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.
The system should initialize before the vehicle
reaches 20 mph (32 km/h). In some cases, it may
take approximately two miles of driving before the
system initializes.
If the system fails to turn on or activate, the
®
StabiliTrak light along with one of the following
messages will be displayed on the Driver
Information Center (DIC) (TRACTION CONTROL
OFF, SERVICE TRACTION CONTROL,
STABILITRAK OFF, SERVICE STABILITRAK).
For 2500 series vehicles, if the vehicle has gone
through heavy acceleration or braking during
the first 2 miles (3.2 km) after starting your vehicle,
these messages may also appear.
348
For 1500 series vehicles, if these DIC messages
appear, make sure the StabiliTrack
has not been turned off, then turn the steering
wheel through either the ten or two o'clock
positions. If this does not clear the message(s),
take your vehicle to the dealer for service. If this is
the case, your vehicle does not need servicing.
Turn your vehicle off and back on again to
reset the system. If any of these messages appear
on the Driver Information Center (DIC), and your
vehicle hasn't gone through hard acceleration
or braking in the first two miles, your vehicle
should be taken in for service. For more
information on the DIC messages, see Driver
Information Center (DIC) on page 244.
You may also feel or hear the system working;
this is normal.
