User and installation guide Document 912 9001 Rev H August 2014 11 Safety Warning This product is designed to monitor vehicle tyre pressures and temperatures it is not designed to provide warnings of sudden catastrophic tyre failure blowouts caused by external influences The driver should always react promptly to warnings The driver should not assume that because the TPMS system has not reported any problems no problems with the tyres or the vehicle exist This product is a proactive safety system It cannot eliminate accidents caused by tyre failure but it does give alert to drivers about abnormal and possibly dangerous tyre conditions Whenever the system alerts to a problem pull the vehicle over as soon as it is safe to do so and ascertain the cause of the alert Depending on the type of tyres fitted to your vehicle in many cases low tyre pressure cannot be determined by simply visually inspecting the tyre If the system alerts to a low tyre pressure in all probability it is because the tyre pressure is dangerously low even though the tyre may look fine Tyres can fail for other reasons besides low pressure overheating or overloading Always be on the alert for other tyre related problems indicated by unusual noises vibrations uneven tread wear or bulges on the tyre If any of these signs are detected have the tyres checked immediately by a professional 12 Replacing valve caps The sensor transmitter modules are supplied
