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 TirePressure) warning light on the instru
ment panel cluster. The low tire pressure
warning light will remain on until youcorrect the tire pressure. ACHECK TIRE
PRESSURE message will also appear
on the DIC.
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must fill the tire to theproper tire inflation pressure (just as youmust refuel the vehicle when the low
fuel warning light illuminates). The Tireand Loading Information label shows thecorrect inflation pressure for the tireswhen they’re cold. “Cold” means your
directional control of the vehicle in
difficult driving conditions. It turns onautomatically every time you start yourvehicle.
To limit wheelspin and help maintain
directional control, you should always
leave the system on. However, if yourvehicle becomes stuck and rocking thevehicle is required, the system should
be turned off.
To turn off the traction control part of
the system, press the (StabiliTrak)
button located below the climate con
trols on the instrument panel.
To turn off the traction control and stabil
ity enhancement systems, press andhold the button for five seconds.
When the system is turned off, the
StabiliTrak light will illuminate.
