SERVICE TIRE MONITOR
This message displays if a part on the Tire Pressure
Monitor System (TPMS) is not working properly. The tire
pressure light also flashes and then remains on during
the same ignition cycle. See Tire Pressure Light on
page 3-41. Several conditions may cause this message
to appear. See Tire Pressure Monitor Operation on
page 5-69 for more information. If the warning comes on
and stays on, there may be a problem with the TPMS.
See your dealer/retailer.
STABILITRAK ACTIVE
This message displays anytime the StabiliTrak ® system
activates to maintain vehicle stability. Any combination
of engine speed management, brake traction control,
and stability control displays this message.
STABILITRAK NOT READY
This message may display if driving conditions delay
StabiliTrak
® system initialization. This is normal.
Once the system initializes, this message will no
longer be displayed on the DIC.
STABILITRAK OFF
This message displays when you press the StabiliTrak ®
button for more than five seconds or when stability control
has been automatically disabled. The StabiliTrak
® button
is located on the transmission shift handle. 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 Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow on page 4-33. To turn the StabiliTrak
®
system back on, press the StabiliTrak ® button again.
There are several conditions that can cause this
message to appear.
• The message may display if the brake system
warning light is on. See Brake System Warning
Light on page 3-38.
• The message displays if the vehicle is shifted
into 4LO.
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
