When we need to do tire alignment operation The sensor fix to the tire by Front-left/Front-right/Back-left/Back-right. Tire alignment can only be done after tire position exchange. 2. When TPMS will give out the alarm? During in the course of driving, if the tire nail leak, pressure is too high or too low, the temperature is too high, the battery is low, the icon will be light on and machine will give out alarm. 3. Complete TPMS installation, a tire does not display data information? A. Car can only receive tire pressure sensor data in driving. B. Check whether the distance between the receiver host and the tire pressure receiver is within a reasonable range. If the distance is reasonable, please re-pair. C. The above method can not solve the problem, please contact customer service center. 4. When receiver host turn no, why tire pressure data is not show on the display at once? In order to reduce power consumption and extend the service life of the sensor, the sensor will not transmit the signal at the time of car parking and the tire pressure is not abnormal. At this point we need to start the can, the speed is faster than 20KM / H and exercise a distance, the sensor will goes into timing launch mode, to transferred real-time update data so that receiver host will show on the display. Reminder 1. Please use this product correctly and use it within its permitted range. 2. The installation process should be strictly in accordance with the contents of manual operation, be sure to have experienced tires to install technicians to disassemble, if due to improper installation and bring undesirable problems, the Company will not be responsible for any problem. 3. When you need to dismantle the tire, please pay attention to tire pressure sensor, to avoid any damage caused. 4. In the set threshold, to strictly comply with the scope of the threshold, different models should be in accordance with its tire parameters or instructions. Sales agents set the range and parameters already, which we do not need to modify. 5. Please check battery capacity daily. It is special require to do check before your driving.
