When the engine is locked and won't start, the steps to follow are: 1. Insert the key and turn it to power on the vehicle, then turn it off, repeating this process three times consecutively; 2. Disconnect the negative terminal of the battery for about ten seconds to clear the engine's protection data, then reconnect the battery and attempt to start the engine again. The reasons for the engine being locked include: 1. Malfunction of the anti-theft system; 2. Illegal opening of the car door; 3. Insufficient battery power or disconnection. The working principle of the engine being locked is: The car ignition key contains an electronic chip with a fixed ID. When the ID of the key chip does not match the ID of the engine, the car automatically cuts off the circuit, preventing the engine from starting.

What is the solution for hard brakes that can't stop when the air conditioner is on?

If the brakes become hard when the air conditioner is on, the vehicle should be sent to a 4S shop for repair as soon as possible. Below is relevant information about brakes: 1. Definition: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. The braking device, also known as a decelerator, is a mechanical braking device that can slow down the vehicle speed. 2. Classification: Braking is divided into emergency braking and daily braking. During emergency braking, be aware of the potential hazard of rear-end collisions.

What does 'rear' mean in Volkswagen air conditioning?

In Volkswagen air conditioning, 'rear' refers to the rear windshield defogger button. Pressing this button can remove fog from the rear windshield. The literal meaning of 'rear' is the back or rear part. When this button appears in a car's air conditioning system, it actually functions as the rear windshield defogger. However, many car models now omit the English word 'rear' and simply use an icon instead. Taking the Passat as an example: it is a front-wheel-drive sedan powered by a water-cooled engine, with dimensions of 4870mm in length, 1834mm in width, and 1472mm in height, and a wheelbase of 2803mm.
