TIRE PRESSURE MONITOR

The Low Tire Pressure warning light on the instrument cluster illuminates when one
or more of the vehicle's tires is significantly underinflated. Fill the tires to the proper tire
pressures listed on the Tire and Loading Information label, located below the driver's
door latch. Current tire pressures can be viewed on the Driver Information Center.
The Tire Fill Alert provides visual and audible alerts to help when inflating a tire to the
recommended tire pressure (does not apply to spare tire). When the recommended
pressure is reached, the horn sounds and the turn signals change from flashing to solid.
