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
Pressure) warning light, which will remain
on until you correct the tire pressure.You
may also have a CHECK TIRE PRES-
SURE message appear on the DIC (if
equipped).
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must fill the tire to the
proper tire inflation pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct inflation 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 remove the DIC mes-
sage 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 the vehicle. This
could be an early indicator that your tire
pressures are getting low and need to
be inflated to the proper pressure.
Note: The Tire Pressure Monitor can alert
you about low tire pressure, but it doesn't
replace normal monthly tire maintenance.
