Tire pressure information is transmitted wirelessly to the receiver. The system checks the tire pressures when speed exceeds 19 mph (30 km/h). The system is self-programming which means that the wheels can be shifted around without any need for adjustment. The spare wheel has no sensor. The sensor batteries last for 10 years or around 160 000 km. The battery cannot be replaced. The whole sensor must be replaced. The system does not warn if the tire pressure is too high. Automatic tire pressure monitoring system WARNING The system is an aid to the driver. The driver always has the responsibility that the tires have the correct air pressure. For optimum safety, economy and comfort tire pressures should be checked regularly even if the automatic tire pressure monitoring has not alarmed. The system consists of a sensor in each wheel and a commopn receiver. The sensors are located inside the tire in direct connection with the air pressure valves. Make sure that wheels with sensors for tire pressure monitoring are fitted during replacement if the car has automatic tire pressure monitoring. Valve with sensor
