vehicle and check for the message on the DIC display.
If the message is still displayed, or appears again when

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
žactivates 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.
3-61

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
Stabilitrak
žsystem. 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 bene®t of Stabilitrak
ž,
so reduce your speed and drive accordingly.
STABILITY SYS DISABLED
The STABILITY SYS DISABLED message will turn on
when you press the Stabilitrakžbutton, or when the
stability control has been automatically disabled. To limit
wheel spin and realize the full bene®ts of the stability
enhancement system, you should normally leave
Stabilitrak
žon. However, you should turn Stabilitrakžoff
if your vehicle gets stuck in sand, mud, ice or snow
and you want to ªrockº 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 theStabilitrak
žsystem back on press the Stabilitrakžbutton
again. There are four conditions that can cause this
message to appear. One condition is overheating, which
could occur if Stabilitrak
žactivates 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 3-36. 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.
TIGHTEN FUEL CAP
If the vehicle's fuel cap is not tightened properly this
message may appear along with the check engine light
on the instrument panel. See
Malfunction Indicator
Lamp on page 3-40. Reinstall the fuel cap fully. SeeFilling Your Tank on page 5-7. The diagnostic system
can determine if the fuel cap has been left off, or
improperly installed. A loose or missing fuel cap will
allow fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should turn
this light and message off.

This system relies upon receiving speci®c information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station
name or the call letters will appear on the display instead
of the frequency. RDS stations may also provide the
time of day, a program type (PTY) for current
programming, and the name of the program being
broadcast.
