What to do in an emergency TIRES PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED) As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. When significant temperature changes occur, the tire pressures will need to be adjusted. The pressure will drop approximately 1 psi for each 12 degree temperature drop. If setting tire pressure in a warm garage during the winter, it is possible the TPMS telltale will illuminate after the car has been parked outside. It is important for the safety of the occupants that the tire preform the TPMS system are set correctly. OHD060001 (1) Low Tire Pressure Telltale (2) TPMS Malfunction Indicator Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.) 6 7
