Product Introduction

Thank you for purchasing our Tire Pressure Monitoring System (TPMS). This system is designed to provide you with additional protection when driving. It will warn the condition of the car’s tires in advance. With the TPMS system installed, the pressure and temperature of the tires can be monitored in real time. It will emit a real-time warning sound and a bright flashing icon to inform the driver if any abnormal tire pressure or temperature is detected, which can prevent traffic accidents and ensure the safety of the driver and passengers. In addition, the installation of TPMS can effectively help to improve vehicle comfort, enhance driving safety, reduce overall wear and fuel consumption, and prevent tires puncture.

Product Precautions & Functions

1. Please pay attention to safety during driving. Do not operate and observe the system frequently.
2. The system uses the sensor transmitter to measure the pressure and temperature in the tire and transmit it by wireless signal. The receiver will express the normal tire pressure and temperature with specific values during normal operation. The sensor transmitter will immediately send an alarm signal to the wireless tire pressure monitoring system when any one or more sensor transmitters in the system detect abnormal tire pressure or tire temperature.The TPMS will immediately send out an alarm corresponding to the abnormal condition of the tire when it receives the signal that the tire is abnormal and will flash the corresponding alarm icon or voice and the tire pressure and temperature value simultaneously to inform the driver. The driver needs to check and repair the tire immediately to avoid accidents caused by abnormal tire pressure or excessive tire temperature.
3. Generally, the tire will have natural slight air leakage, and the tire pressure will decrease with time, which is a normal phenomenon and not directly related to the installation of the product.
4. Affected by the thermal expansion and contraction of air, the air pressure is sometimes high and sometimes low during driving, which is a normal phenomenon and has no direct connection with the installation of the product.
5. The incorrect installation of the TPMS system will affect the use of the product or cause product damage. Be sure to hire an experienced tire installation technician to install it. Be careful not to damage the sensor transmitter when you need to disassemble and assemble the tire again. The valve with a built-in sensor transmitter is not suitable for repeated disassembly.
6. Please use a specially configured power cord, and it cannot be tied around the receiver. Otherwise, the machine will be damaged or the signal reception will be affected, and you cannot enjoy the free warranty.
7. 80% of DVD equipment, multi-function rear view mirrors or other high-power equipment in the market have electromagnetic interference. It is recommended that the receiver be more than 50cm(19inch) away from such products to avoid affecting the stability of received signals. The best position in the car is the upper left corner and upper right corner of the A-pillar front gear and the middle of the two front seats (far away from the central control).
8. All information on product performance, specifications and warranty are subject to change without prior notice.
9. The system transmits signals wirelessly. Therefore, under some special environmental conditions, the system may be weakened or fail to receive the signal due to interference factors, wrong operation methods or improper installation methods. Keep the car away from the current position (there may be strong wireless signal interference nearby) if the receiver fails to receive the signal of a tire for 10 minutes or go to the specified tire warranty factory as soon as possible to check whether the sensor in the tire has fault or the battery of the sensor in the tire is exhausted (the battery may need to continuously transmit wireless signals to warn the driver because of frequent abnormal conditions, so that the battery life is shorter than the normal service life).

Application Scope of TPMS System:
The wireless tire pressure monitoring system requires correct installation methods and installation by qualified operators in accordance with the steps in the installation manual, so that the system can operate correctly and provide warranty. If the sensor is damaged due to improper installation or disassembly, it will no longer enjoy the product warranty. The system is applicable to vehicles with 4-6 tires and the maximum tire pressure is lower than 8bar/116psi (gauge pressure).

Abnormal / Alarm Information

Air Leakage Alarm：
When the air pressure of any tire is lower than 26PSI(4-wheel vehicle)/58PSI (6-wheel vehicle) in a launch cycle, the buzzer will sound the alarm rapidly, and the corresponding tire icon, pressure data, TPMS icon and air leakage icon will flash continuously. Press any key to stop the buzzer alarm; The alarm is cleared after the leakage stops.
Low-Pressure Alarm:
When it detects that the pressure of any tire is lower than 75% of the standard tire pressure, the buzzer will sound an alarm, and the corresponding tire icon, pressure data, TPMS icon, and low-pressure icon will flash continuously. When the tire pressure is equal to or higher than the alarm threshold, the alarm will be cleared; The default low-pressure alarm threshold is 26PSI(4-wheel vehicle) /58PSI(6-wheel vehicle), which is suitable for all cars (Reference document: National Standard “GB/T2978-2008 Car Tire Specifications, Dimensions, Pressure, and Load”). For different models, please refer to the tire pressure standard values on the door post of the car or adjust it after consulting the tire shop or reading the instruction manual.
High-Pressure Alarm:
When it is detected that the vehicle is fully loaded and the pressure of any tire is 125% higher than the standard tire pressure value of cold tire, the buzzer will sound, and the corresponding tire icon, pressure data, TPMS icon, and high-pressure icon will flash continuously. When the tire pressure is lower than the warning threshold value of 0.1 bar, the alarm will be cleared; The default setting of the high-pressure alarm threshold is 43PSI(4-wheel vehicle)/97PSI (6-wheel vehicle), which is suitable for all cars. (Reference document: National Standard “GB/T2978-2008 Car Tire Specification, Dimensions, Pressure and Load”). For different models, please refer to the tire pressure standard values on the door post of the car or adjust it after consulting the tire shop or reading the instruction manual.
High-Temperature Alarm:
When it detects that the temperature of any tire is higher than the preset temperature threshold, the buzzer will sound the alarm, and the corresponding tire icon, temperature data, TPMS icon and high-temperature icon will flash continuously.
