System Scope of Use and Warnings
Tire Pressure Monitoring System, TPMS
This system is a sensing device designed to measure and display tire operation and / or
activate an alert to the driver when pressure and temperature irregularities are detected. It is
the responsibility of the driver to react promptly and with discretion to alerts. Abnormal tire
inflation pressure should be corrected at the earliest opportunity.
Caution: The system is wireless RF product; therefore, it may not receive signal due to
interference environment or incorrect operating or installation. When the system continually
cannot receive signal from one of the tire sensor more than 20 minutes since the system be
switched on, the system will show “ E2 ”. In this case, it may cause by a RF interference
environment and driver need to drive the vehicle to other place. If the display still cannot
receive any correct signal from tire sensor, then, driver needs to find a nearby qualified tire
maintain service for checking and maintain. It may cause by a tire sensor damaged or battery
power consumption is low (the battery consumption will be lower than under normal using
condition due to sensors need to send warning signal continually to driver) . If the system
continually cannot receive signal from any sensors more than 20 minutes, the system might
damaged and will show “E1”. Driver needs to drive to other place (there might be a
interference nearby) or send the system to agent for repair
＊System Installation and Usage
Use of the TPMS requires that qualified personnel according to the instructions here have
properly installed it. This system is suitable for use on a passenger car, SUV and 4X4 tires,
with up to maximum cold inflation pressure of 74 Psi (Guage) ,below instruction is Guage
value mentioned.
＊Reacting to Alerts
When an alert or warning is received, reduce vehicle’s speed and proceed to a safe location
to stop where the tire can be inspected and /or serviced.
