For the alarm caused by low tire pressure, we must first ensure that there is no air leakage caused by puncture, and then correct the cold tire pressure according to the vehicle nameplate recommendation. After the correction, the warning message of low tire pressure will be automatically cancelled after driving for a few minutes.
It should be pointed out that:
The tire correction pressure should be set to the recommended cold tire pressure to adapt to different driving conditions. Check and correct the tire pressure every month when the tire is cold. The tire is cold under the following conditions:
● The vehicle should be parked for at least 3 hours without direct sunlight;
● The vehicle should not travel more than 1.6km ... When calibrating the tire pressure in cold state, the value measured by the pressure gauge may be different from that measured by the tire pressure monitoring system, which shall prevail.
It should be pointed out that:
Tire pressure monitoring system assists drivers to monitor tire pressure, which can provide very effective early warning, but it can't completely prevent accidents.
The tire pressure displayed when the vehicle is running is the current actual tire pressure; When the vehicle is stationary, the tire pressure will not be displayed or the displayed value is for reference only.
When changing the tire or changing the tire position of the original car, please go to the authorized service outlets of Changan Automobile for replacement and matching, so as to avoid damaging the sensor due to improper operation or causing the tire pressure value display position to be inconsistent with the actual car.
It should be pointed out that:
Only when all four wheels are equipped with corresponding sensors can the tire pressure detection system work. The tire pressure sensor is not installed in the spare tire, and the tire pressure fault light will light up after replacing the spare tire for a period of time. Please install the sensor specified by the factory and complete the sensor learning.
Please stay away from the following driving conditions as far as possible, because under these conditions, the tire pressure sensor may be disturbed, resulting in abnormal lighting of the tire pressure system fault indicator and prompting the tire pressure system fault:
● Vehicles are driving near power lines or radio transmitters (such as airports and transmission towers). );
● Use radio transmitters (such as wireless headsets and driving recorders). ) in or near the car;
● The vehicle is equipped with snow chains.
If the above situation is eliminated, the tire pressure system fault indicator light is still on, and the instrument feeds back the tire pressure system fault. Please drive carefully and go to Changan Automobile authorized service outlets for maintenance as soon as possible.
Because there is no tire pressure sensor for snow tires, if the vehicle replaces snow tires in winter, the tire pressure fault indicator light will light up and the tire pressure system will prompt. In order to prevent this known alarm failure, you can turn on the winter mode at the authorized service outlets of Changan Automobile to shield the invalid tire pressure alarm.
Calibration of tire pressure in warm environment may trigger a low pressure alarm when entering cold environment, which is caused by pressure change caused by temperature change and does not mean system failure. When driving in different temperature areas, the tire inflation pressure should be checked and calibrated in time.
Special attention should be paid to:
If the tire pressure monitoring system detects that the air pressure of one or more tires is low, a low pressure warning message will appear on the instrument display screen. At this time, please slow down and brake to stop, try to avoid sharp turns, drive carefully to avoid danger and find a good maintenance point. When the tires are cold, correct the tire pressure to ensure that the four tire pressures are at the recommended cold tire pressure level on the vehicle nameplate.
