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.
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 4-45. 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 3-37. 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 3-42. Reinstall the fuel cap fully. See
Filling Your Tank on page 5-8. 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.
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 Stabilitrak
System on page 4-9 for
more information.
