For a car that hasn't been driven for a long time, it's recommended to warm it up for about 30 seconds to 1 minute. The method for warming up the car is as follows: 1. Start the vehicle and keep the air conditioning turned off; 2. Let the engine idle to warm up; 3. Drive slowly after the engine runs smoothly; 4. Once the temperature gauge rises by 1 to 2 bars, you can drive normally and turn on the air conditioning. The reasons for warming up a car are: 1. After being parked for a long time, the engine oil flows back into the oil pan; 2. Before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to lower temperatures; 3. When parked, the gear oil flows to the lower part of the transmission, leaving the upper part without lubrication during a cold start.
