Notice
System Scope of Use and Warnings
Ɏ
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.
TPMS can monitor and provide tire pressure and tire temperature in real time to help the driver control and keep
the n
ormal tire
pressure in order to reduce the fuel consumption and extend the tire life, and also reduce the
possibility of vehicle breakdown on the road or heavy incident or crash to occur.
Ɏ
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.
Caution
The system is a wireless RF product; therefore, it may not receive a signal due to poor environmental conditions or
incorrect installation. When the system continuously cannot receive any signal from any tire sensor for more than 10
minutes since the system has been switch on, the display will show “ERROR” and activate the alert sound. In this case,
a RF interference environment may have caused it; a driver will need to drive the vehicle to a different location.
If the display is still unable to receive any correct signal from tire sensor, the driver will need to find a nearby qualified
tire maintenance service to check or carry out maintenance. This abnormality may be caused by a damaged tire sensor
or excessive battery power consumption.
