The Tire Pressure Monitor alerts you when a
significant reduction in pressure occurs in
one or more of your vehicle’s tires by illumi
nating the (low tire pressure) warning
light on the instrument panel. The low tirepressure warning light will remain on untilyou correct the tire pressure.
You may also have a CHECK TIRE PRES
SURE message appear on the DIC.
Correcting the Tire Pressure
When the low tire pressure warning light illu
minates, you must fill the tire to the proper
tire inflation pressure. The Tire and LoadingInformation label shows the correct inflationpressure for the tires when they’re cold.“Cold” means your vehicle has been sittingfor at least three hours or driven no morethan one mile.
You can temporarily remove the DIC mes
sage by acknowledging it with your DIC con
trols. However, at the next vehicle startup,the DIC message will reappear if the tirepressure has not been corrected.
You may notice during cooler conditions that
the low tire pressure warning light will appearwhen the vehicle is first started and then turn
off as you start to drive the vehicle. Thiscould be an early indicator that your tirepressures are getting low and need to beinflated to the proper pressure.

you about low tire pressure, but it doesn’treplace normal monthly tire maintenance.
