Can the air conditioning be turned on when the car is turned off?

You can turn on the air conditioning when the car is turned off, but it will not provide cooling function. Moreover, prolonged use may easily lead to battery depletion. Therefore, it is not recommended to keep the air conditioning on for a long time when the car is turned off. If you need ventilation, you should also switch to the external circulation mode to allow fresh air to enter the car. The air sent by the air conditioning is just natural air blown by the blower, as the air conditioning compressor is driven by the engine's power and does not work when the car is turned off. The natural air blown by the blower is powered by the battery, and excessive consumption of the battery by the blower may cause long-term battery depletion. Of course, this only applies to traditional fuel vehicles.

What are the solutions for a dent in the front bumper?

The solutions for a dent in the front bumper are: 1. Use hot water to heat the dented area, which can help pop the dent out; 2. Once the dent is restored to its original shape, immediately cool the area that was heated with hot water by applying cold water to allow the rubber to contract and recover; 3. Remove one of the car's screws, reach inside the bumper from the body, and push from behind to fix the dent. The functions of the front bumper are: 1. To absorb and mitigate external impacts during collisions, providing a cushioning effect to protect both the vehicle and the driver; 2. To harmonize with the vehicle's overall design, offering good decorative appeal.

Where is the Correct Position of the Steering Wheel?

The correct position of the steering wheel is in the middle directly below the car's dashboard. Here is a related introduction to the steering wheel: Function: The steering wheel is generally connected to the steering shaft via splines. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a larger-diameter steering wheel reduces the hand force required from the driver when turning. The steering intermediate shaft serves as a connecting component between the steering gear and the steering shaft, facilitating the standardization of the steering gear, compensating for errors during manufacturing and installation, and ensuring a more rational installation of the steering gear and steering wheel in the vehicle. Fault Diagnosis: Drive at a speed of 15 kilometers per hour on a relatively open road. While driving, turn the steering wheel left and right to check if it operates smoothly and whether there is any lack of return force. Also, observe if the vehicle deviates from its path when the steering wheel is released.
