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.
With the ignition On or in Accessory mode, the Tire Fill Alert will provide visual and
audible alerts when the Low Tire Pressure warning light is on to help with inflating a tire to the recommended tire pressure (does not apply to spare tire). When the recom-mended pressure is reached, the horn sounds and the turn signals change from flashing to solid.
