Service Tire Monitor; Service Stability; Stability Sys Active - GMC 2003 Yukon Owner's Manual

RIGHT REAR DOOR AJAR
If the passenger's side rear door is not fully closed, this
message will appear on the display and you will hear
a chime. Stop and turn off the vehicle, check the door for
obstacles, and close the door again. Check to see if
the message still appears on the DIC. Press the select
button to acknowledge the message and clear it
from the DIC display.

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

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.
