What is the reason why the Passat's brake cannot be pressed down and the engine cannot start?

[Isaiah]

Reasons why the Passat's brake cannot be pressed down and the engine cannot start: the car's steering wheel is locked; the car battery is dead. Battery maintenance precautions: 1. Avoid long-term parking: the battery installed in the car will self-discharge during long-term parking. Many car owners find it difficult to start the car or even the battery is completely dead after returning from a business trip or travel. Therefore, it is best to drive the car once a week, and the driving distance should be at least 20 minutes, so that the battery can be charged while the car is running. 2. Turn off the air conditioning and audio before turning off the engine: the air conditioning system involves the compressor and blower, and the audio is also a high-power electrical equipment. If they are not turned off before turning off the engine, they will automatically start the next time the car is started, which will cause a heavy burden on the battery and damage the battery.
