Tire Pressure Monitoring Systems, TPMS
Tire Pressure Monitoring Systems (TPMS) improves safety while driving. Once installed in your
vehicle, the system will automatically monitor your tires in real-time for pressure and temperature.
When any tire’s pressure and/or temperature appear abnormal, the system will, in real-time,
transmit signals to active an alarm and show a digital figure to warn the driver of a problem. The
system aids safety, can extend the tire life and help reduce fuel consumption.

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 a signal due to the poor
environment or incorrect operating or incorrect installation. When the system continually cannot
receive any signal from any tire sensor more than 10 minutes since the system be switch on
power for monitoring, the system will show “ E2 ” and turn on the RED abnormal tire LED light
and alert sound. In this case, it may cause by a RF interference environment, a driver need to
drive the vehicle and leave this place. If the display still cannot receive any correct signal from tire
sensor, then, a driver need to find a nearby qualified tire maintain service for checking and
maintain. It may cause by a tire sensor damages or battery power consumption. (Battery in
normal condition can be used more than 7 year, but in abnormal condition, the tire sensor will
continually send warning signal for drivers, thus it will consumption the battery quickly than
normal prediction.)
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.
Manual for Tire Pressure Monitoring Systems, TPMS
3/21
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.
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.

System Installation
There are two parts of system installation
1. Setting up the display unit in the vehicle
2. Installing the transmitter unit sensor in each tire.
We strongly suggest installing the display unit first, and then install the tire transmitters.
Note: Warranty does not cover “Tire Valves” and “Screws for Tire Valves”, all the tire valves and
the screws will need to be replaced with new tire valves and screws when rotating tires, changing
of tires, and changing of Wireless Transmitter sensors. (Whenever a wireless transmitter sensor
is installed or reinstalled, a new tire valve” and “screws for the tire valve” must be used).

fits tightly on the wheel and then tighten the screw for the
transmitter’s sensor so that it is fixed on the wheel.。
7
Clean inside the tire to prevent the tire from damaging the
transmitter sensor.
8
Inflate the tires.
Balance the tire
a. Balance tires using a balance machine
b. A lead tire weight may need to be added for balancing.
c. Balance until the tire balance shows balance as “OK”
The Steps above will require the assistance of a tire fitting
service or a mechanic. It is important that the wheels are
balanced after the fitting of the TPMS sensors in order to
ensure the safe operation of the tire when refitted to the
vehicle.。
9 Set up the other three tires in the same manner.
10
Turn the ignition key of the vehicle until the power is
activated on the cigar lighter, this may be first or second
position depending on the car manufacturer. The in-car
display will be activated.
The function button of the display unit can be switched to
pressure or temperature depending on the customer’s
need.
System Operation
Once installed the system will automatically monitor the tires when power is applied. When the
power of the vehicle is switched on, the display unit will show, in real-time, the pressure of all the
tires simultaneously.

System Alarm
The alarm system will start, if tire pressure is too low, and if tire temperature is too high, the alarm
system will start too. If high tire temperature and low tire pressure situation happen at the same
time, the system will show low tire pressure at first and then show tire temperature, both of tire
pressure and temperature will show on the screen for six seconds by turns.
The alarm will keep making sound till turning off alarm system or solving abnormal situation, and
below the manual will explain operation process.
Setup Method
The driver can follow the steps to adjust the system of pre-loaded values
