TIRE PRESSURE MONITORING SYSTEM
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 listed on the Tire and Loading Information label, located on the driver’s

mended air pressure (excluding the spare tire). With the vehicle On, the horn sounds
and the turn signals change from ashing to solid when the recommended pressure is
reached.
