When we need to do tire alignment operationThe sensor fix to the tire by Front-left/Front-right/Back-left/Back-right. Tire alignment can only be doneafter tire position exchange.2. When TPMS will give out the alarm?During in the course of driving, if the tire nail leak, preure is too high or too low, the temperature is toohigh, 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 preure sensor data in driving.B. Check whether the distance between the receiver host and the tire preure receiver is within areasonable 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 preure 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 nottransmit the signal at the time of car parking and the tire preure is not abnormal. At this point we needto start the can, the speed is faster than 20KM / H and exercise a distance, the sensor will goes into timinglaunch mode, to transferred real-time update data so that receiver host will show on the display.Reminder1. Please use this product correctly and use it within its permitted range.2. The installation proce should be strictly in accordance with the contents of manual operation, besure to have experienced tires to install technicians to disaemble, if due to improper installation andbring undesirable problems, the Company will not be responsible for any problem.3. When you need to dismantle the tire, please pay attention to tire preure sensor, to avoid any damagecaused.4. In the set threshold, to strictly comply with the scope of the threshold, different models should be inaccordance 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.
