As soon as the weather was cold, BYD Song pro dashboard jumped out of the tire pressure.

1. In winter, when the outside temperature is low and the vehicle has not driven for a period of time, the tire pressure will drop and the indicator light will light up. This situation needs to be pressurized in time.

2. In winter, due to the principle of expansion due to heat and contraction due to cold, the tire pressure in winter will decrease, which will cause the indicator light to light up, and the tire pressure light can also be turned on and off by pressurization.

3. In addition, the tire pressure light is on in winter, because the tire accidentally sticks into the nail and causes air leakage. At this time, it is necessary to repair or replace the tire.
