7-38 Starting and operating/Tire pressure monitoring system (TPMS) function is operating. – The sensation of depressing the brake pedal is different, (harder than usual etc.) when the brake pedal is depressed during hill descent con- trol function operation. Tire pressure monitoring system (TPMS) (if equipped) S07AO ! Hill descent control indicator S07BI0301 Low tire pressure warning light This indicator appears while the hill des- cent control function is in the standby mode. It flashes while the function is operating. It will disappear when the function is in the disabled mode. When this function is changed from operational to non-operational, it will disappear when the vehicle speed reaches more than approximately 18 mph (30 km/h). The tire pressure monitoring system pro- vides the driver with a warning message by sending a signal from a sensor that is installed in each wheel when tire pressure is severely low. The tire pressure monitoring system will activate only when the vehicle is driven at speeds above 20 mph (32 km/h). Also, this system may not react immediately to a sudden drop in tire pressure (for example, a blow-out caused by running over a sharp object). WARNING . If the low tire pressure warning light illuminates while driving, never brake suddenly. Instead, perform the following procedure. Otherwise an accident involving serious vehicle damage and ser- ious personal injury could occur. (1) Keep driving straight ahead while gradually reducing speed. (2) Slowly pull off the road to a safe place. (3) Check the pressure for all four tires and adjust the pressure to the COLD tire pressure shown on the vehicle placard on the door pillar on the driver’s side. Even when the vehicle is driven a very short distance, the tires get warm and their pressures in- crease accordingly. Be sure to let the tires cool thoroughly be- fore adjusting their pressures to the standard values shown on the tire placard. Refer to “Tires and wheels” F11-22. The tire pres- sure monitoring system does not function when the vehicle is sta-
