Service Stability; Stability Sys Active; Service Tire Monitor; Stability Sys Disabled - GMC 2004 Yukon XL Owner's Manual

SERVICE STABILITY

If you ever see the SERVICE STABILITY message,
it means there may be a problem with your Stabilitrak
system. If you see this message try to reset the
system (stop; turn off the engine; then start the engine
again). If the SERVICE STABILITY message still
comes on, it means there is a problem. You should see
your dealer for service. The vehicle is safe to drive,
however, you do not have the benefit of Stabilitrak
so reduce your speed and drive accordingly. Press the
select button to acknowledge the message and clear
it from the DIC display.

SERVICE TIRE MONITOR

If your vehicle is equipped with the Tire Pressure
Monitor System, this message will be displayed if one or
more of the tire monitor sensors have malfunctioned,
or if all of the tire monitor sensors have not been
programmed successfully. Press the select button or
reset stem, to clear it from the display. The message will
reappear at each ignition cycle until the system has
been serviced.

STABILITY SYS 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're 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 DISABLED

The STABILITY SYS DISABLED message will turn on
when you press the Stabilitrak
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
®
button, or when the
®
off
