STARTING AND DRIVING CAUTION D The use of non−genuine wheels will cause the air pressure sensors to transmit the electronic code in different manner, resulting in the system failure. D The use of different type of tires with genuine wheels may also cause the malfunction of the system. CAUTION 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 (tire and load information label). (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label (tire and load information label), you should determine the proper tire inflation pressure for those tires.) 390
