Tire Pressure Monitor
(if equipped)
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 instrument panel cluster.
The low tire pressure warning light will
remain on until you correct the tire pressure.
A CHECK TIRE PRESSURE message may
also 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 clear the DIC message
by acknowledging it with your DIC controls.
However, at the next vehicle startup, 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.
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.
