with the StabiliTrak
®system. If you see this
message, try to reset the system. Stop; turn off
the engine for at least 15 seconds; then start
the engine again. If this 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 benet of
StabiliTrak
®, so reduce your speed and drive
accordingly.
SERVICE SUSPENSION SYSTEM

Autoride
®suspension system is not operating
properly. Have your vehicle serviced by your
dealer.

page 137for more information.
SERVICE TIRE MONITOR SYSTEM
If your vehicle has the Tire Pressure Monitor
(TPM) system, this message will display if a part
on the system is not working properly. If you
drive your vehicle while any of the four sensors
are missing or inoperable, the warning will
come on in about 20 minutes. A sensor would be
missing, for example, if you put different wheels
on your vehicle without transferring the sensors.
If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.

display when there is a problem with the traction

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

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 233.
The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
If an engine or vehicle related problem has
been detected and the vehicle needs
service, the message will appear. See your
dealer.
The message will also appear if the vehicle is
shifted into 4LO.
The message will turn off as soon as the
conditions that caused the message to be
displayed are no longer present.

this message may display along with the check

page 426. 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.
TIRE LEARNING ACTIVE
If your vehicle has a Tire Pressure Monitor (TPM)
system, this message will display when the
system is re-learning the tire positions on your
vehicle. See “DIC Operation and Displays (Using
DIC Buttons)” earlier in this section for more
information. The tire positions must be re-learned
after rotating the tires or after replacing a tire
or sensor. SeeTire Inspection and Rotation on
