Avoid parking the car in an open-air parking lot for a long time. If it is parked for a long time, the battery should be removed and taken away to prevent it from freezing and damaging. The engine of the car is not easy to start in winter. The time for each start should not exceed 5 seconds, and the interval time for the next start should be no less than 15 seconds. If it still can't be started after many starts, the reason should be found from other aspects such as circuit, ignition coil or fuel supply. Avoid starting many times continuously, which will cause the battery to be burned out due to excessive discharge.
