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.
SERVICE STABILITY
If you ever see the SERVICE STABILITY message, it
means there may be a problem with your
StabiIitrak@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.
STABILITY SYS 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
You Are Stuck: In
Sand, Mud, Ice or
Snow on page 4-41. To turn the
Stabilitrak@system back on press the Stabilitrak@button
again. There are four 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 3-34. The
message could be displayed
if the stability system takes
longer than usual to complete its diagnostic checks
due to driving conditions. Also,
if an engine or vehicle
related problem has been detected, and the vehicle
needs service, the message will appear.
The message will turn off as soon as the conditions that
caused the message to be displayed are no longer
present.
TRACTION ACTIVE
When the traction control system has detected that any
of the vehicle’s wheels are slipping, the traction
control system will activate and this message will appear
on the DIC. See StabiIitrakO System
on page 4-9 for
more information.

your vehicle
- like a tape player, CB radio, mobile
telephone or two-way radio
- be sure you can
add what you want. If you can, it’s very important to
do
it properly. Added sound equipment may
interfere with the operation of your vehicle’s engine,
Delphi Electronics radio or other systems, and
even damage them. Your vehicle’s systems may interfere with the operation of sound equipment that
has been added improperly.

how to operate all
of its controls to be sure you’re getting
the most out of the advanced engineering that went
into it. Your
vehicle may have a feature called Retained
