The

Low Tire Pressure warning light on the instrument cluster illuminates when one

or more of the vehicle’s tires is signicantly underinated. Fill the tires to the proper tire

pressures. The proper tire pressures for the vehicle are listed on the Tire and Loading

Information label, located below the driver’s door latch. Current tire pressures can be

viewed in the Driver Information Center.

ing light illuminates when the vehicle is rst started in cooler temperatures and then turns

off as the vehicle is driven, check for the proper tire pressures.
