PERFORMANCE & MAINTENANCE
StabiliTrak
®
– Stability Control
System
StabiliTrak is an advanced computer-
controlled vehicle stability and traction
enhancement system that assists with
directional control of the vehicle in
difficult driving conditions. It turns on
automatically every time you start your
vehicle.
To limit wheelspin
and help maintain
directional control,
you should always
leave the system
on. However,
if your vehicle
becomes stuck
and rocking the vehicle is required,
the system should be turned off.
• To turn off the traction control part
of the system, press the
(StabiliTrak/Traction Control) button
located on the center of the instru-
ment panel.
• To turn off both traction control and
StabiliTrak, press and hold the button
for five seconds. Press the button
again to turn on both systems.
When either system is turned off, the
(StabiliTrak/Traction Control) light
will illuminate.
See Section 4 of your Owner Manual.
Tire Pressure Monitor
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the
(Low Tire
Pressure) warning light on the instru-
ment panel cluster. The low tire pressure
warning light will remain on until you
correct the tire pressure. A CHECK TIRE
PRESSURE message will also appear
on the Driver Information Center (DIC).
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily clear the DIC
message by acknowledging it with your
DIC controls. However, at the next
vehicle start-up, the DIC message will
reappear if the tire pressure has not
been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Note:
The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
