If the car lights turn on by themselves after locking the vehicle, it is generally a normal function of the car. Below are the details: 1. Equipped with AUTO light's 'Coming Home/Leaving Home' feature: This situation occurs because the vehicle is equipped with the AUTO light's 'Coming Home/Leaving Home' feature. If it is not the 'Leaving Home' feature being activated, it is necessary to check and confirm at a maintenance facility as soon as possible. The 'Coming Home' and 'Leaving Home' features of the headlights are activated through the AUTO function. These features keep the headlights on for a period after the vehicle is locked, providing illumination for the driver when leaving the garage. The AUTO function mainly eliminates the need for the driver to manually turn on the headlights, as the vehicle determines whether to illuminate the headlights based on the brightness sensor outside the car. 2. General activation of the 'Leaving Home' feature: At night, pressing the unlock button on the remote key while the light switch is in the AUTO position will automatically turn on the headlights. Activation of the 'Coming Home' feature: After turning off the ignition switch, operating the headlight flasher will turn on the headlights to provide illumination for the user for a certain period.

How to steer when the front of the car tilts to the left while reversing?

When the front of the car tilts to the left while reversing, it indicates that the rear of the car is deviating to the right. In this case, you should steer the wheel to the left. Below are detailed instructions on steering wheel usage: 1. Steering wheel usage: If you visualize the steering wheel as a clock face, the correct hand position is to place the left hand between the 9 and 10 o'clock positions and the right hand between the 3 and 4 o'clock positions. This posture provides better support for the body in the event of a collision. If you only grip the steering wheel with four fingers and rest the thumb on the wheel, when the wheels hit a rock or a high curb, the front wheels may suddenly turn to one side, causing the steering wheel to rotate rapidly, which could potentially break the thumb. 2. Precautions: Improper steering during turns is most likely to cause accidents, so it's best to reduce speed when turning. When entering a curve, gradually turn the steering wheel according to the curve's arc. Begin to straighten the wheel when the front of the car is about to align, and fully straighten the wheel after completing the turn before accelerating forward.

How to Deal with Blue Screen in Rearview Camera?

Rearview camera blue screen is caused by camera failure, and replacing the camera can solve the problem. Here are specific details about the rearview camera: 1. Introduction: The rearview camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. 2. Function: This system provides a more intuitive and clear view of the rear situation when reversing, making it one of the most practical configurations for reversing safety. When the reverse gear is engaged, the system automatically activates the high-definition rearview camera located at the rear of the vehicle, displaying a clear image of the rear situation on the LCD screen.

Should You Use a Low Gear or High Gear on Bumpy Roads?

When driving on bumpy roads, shift to a lower gear and gradually release the accelerator pedal. Here are the specific details about driving on bumpy roads: 1. Reason for gradually releasing the accelerator pedal: Gradually releasing the accelerator pedal helps maintain a slow and steady speed to pass through the bumpy section, allowing the vehicle to idle forward. When the vehicle is moving slowly, a sudden release of the accelerator pedal can cause jerking, which affects the vehicle's transmission system. Therefore, it is advisable to release the accelerator pedal slowly during normal operation to avoid jerking. 2. Reason for shifting to a lower gear: Shifting to a lower gear provides more engine traction. Using a low gear to idle or slightly accelerate can reduce the impact from uneven road surfaces and alleviate body vibrations.

Why is the reversing camera image dim?

Reversing camera image dimness is caused by low temperature. Here are specific details about reversing cameras: 1. Introduction: The car reversing camera is a complete system, which can also be formed by adding a camera device and an in-car display. The 360-degree panoramic view system compensates for the domestic limitation of only providing images through radar or a single rear-view camera. 2. Panoramic view: The panoramic view system can have four video outputs, namely front, rear, left, and right. Cameras are installed at the front of the car, the rear, and under the side mirrors. Controlled remotely, it can automatically switch between views, which can be composed of four videos or a single video, enhancing anti-theft monitoring and driving safety.

What causes the ignition warning light to come on and then disappear after starting?

It is normal for the ignition warning light to come on and then disappear after starting. The warning light coming on after ignition is part of the self-check procedure, and the light turning off indicates that the car is functioning properly. Below are some faults related to the ignition warning light staying on: 1. Ignition system failure: A faulty ignition system can lead to poor engine combustion, requiring inspection and repair of the ignition system. 2. Carbon buildup: Excessive carbon buildup on spark plugs, irregular sparking, or no sparking can cause this issue, necessitating cleaning or replacement. 3. High-voltage coil pack: The high-voltage coil pack or high-voltage coil may be faulty, requiring checks on voltage and resistance to ensure they are normal. 4. Component failure: Faulty related components can result in poor combustion in the engine cylinders, triggering the ignition warning light.

How Often Should You Wash Your Car?

It is recommended to wash your car every two weeks, averaging 2 to 3 times per month. Additionally, waxing should be done every 3 months. New cars do not require waxing as they come with a factory-applied wax layer; waxing can be done after six months. The frequency of car washing should be determined based on the vehicle's condition, including the local environment, weather, and season. To slow down paint aging, you can apply wax after washing to protect the paint, with waxing needed every 3 months. It is also advisable to wash the car immediately after rain, as rainwater is acidic and carries dust, which can significantly damage the paint. For better paint protection, parking the car in an underground garage is ideal, as exposure to the sun's ultraviolet rays accelerates the aging of the car body. If the car is not washed for an extended period, acidic components in the air, along with harmful substances like bird droppings and dust, can erode and adhere to the paint surface, speeding up paint aging and damage. Paint damage can also expose the metal parts of the car body to oxidation due to loss of protection, leading to premature vehicle deterioration. However, car washing should not be too frequent and should be adjusted according to needs.
