STABILITY SYS ACTIVE
You may see the STABILITY SYS ACTIVE message on

system has come on to help your vehicle continue to
go in the direction in which you are 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®button or when the
stability control has been automatically disabled. To limit
wheel spin and realize the full benets 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. SeeIf Your
Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-49.
To turn the StabiliTrak
®system back on, press the
StabiliTrak®button again.
There are several 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. SeeBrake System
Warning Light on page 3-43.
The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.

caused the message to be displayed are no longer
present.

If the vehicle’s fuel cap is not tightened properly, this
message may appear along with the check engine light
on the instrument panel. SeeMalfunction Indicator Lamp
on page 3-48. Reinstall the fuel cap, making sure to fully
install the cap. SeeFilling the 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 the
light and message off.
TRACTION ACTIVE
When the traction control system has detected that any
of the vehicle’s wheels are spinning, the traction
control system will activate and this message will appear
on the DIC. For more information, seeTraction Assist
System (TAS) on page 4-8.

braking, brake traction control will be displayed and the
TRACTION SYS LIMITED message will be displayed.
The system will return to normal operation after the
brakes have cooled.

If the transmission uid in the vehicle gets hot, this
message will appear on the DIC and you will hear a
chime. The chime will stop when the transmission uid
temperature is less that 265°F (129°C). Driving with
the transmission uid temperature high can cause
damage to the vehicle. Stop the vehicle and let it idle to
allow the transmission to cool. This message will
clear when the uid temperature reaches a safe level.
SeeTransmission Temperature Gage on page 3-46.
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while transmission
temperature warning is displayed.

of sound equipment that has been added.
Notice:The chime signals related to seat belts,
parking brake, and other functions of your vehicle

Radio Data System (RDS)
The audio system has a Radio Data System (RDS).
RDS features are available for use only on FM stations
that broadcast RDS information.
With RDS, the radio can do the following:
Seek to stations broadcasting the selected type of
programming
Receive announcements concerning local and
national emergencies
Display messages from radio stations
This system relies upon receiving specic 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 the radio is tuned to an RDS station, the station
name or 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.
