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 needs 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 (Gauge), below instruction is Gauge 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.
The low-pressure alert indicates that the air pressure has dropped to a selected minimum and a
high-temperature alert indicates that the temperature of the tire content has surpassed the
threshold value set. When the battery voltage icon flash, it means the battery voltage of vehicle is
below battery voltage default (11v).
＊Use of Chemicals
Temporary resealing or re-inflation products containing internal sealants or propellants in any tire
assembly may adversely affect the operation of the sensor/transmitter.
