What Are the Causes of Parking Brake Malfunction Warning?

Parking brake malfunction warning causes: 1. Insufficient brake fluid; 2. Damaged brake pads; 3. Handbrake not released or not fully disengaged; 4. Excessive brake clearance. The parking brake, commonly known as the handbrake, primarily functions to prevent vehicle rollaway by applying a sustained and stable braking force after parking. The handbrake is typically positioned within easy reach of the driver's right hand for convenient operation. Some automatic transmission models on the market feature a foot-operated parking brake (with identical functionality) located outside the driver's left foot, while certain models may be equipped with an electronic parking brake system. To engage the parking brake, the driver should firmly press the brake pedal downward and pull the parking brake lever upward.

Which Lights Should Be Turned On When Driving at Night?

When driving at night, turn on the low beam when visibility is good and there is a vehicle ahead, and switch to the high beam when visibility is poor and there is no vehicle ahead. The functions of car lights: 1. Low beams are used for driving in urban areas at night, where street lighting is generally sufficient, allowing drivers to see the road ahead clearly; 2. High beams are used in rural areas or on roads without street lighting; 3. Turn signals are used to indicate turning intentions to other vehicles and pedestrians, serving as a warning; 4. Reverse lights illuminate when reversing, helping to light up the road and obstacles behind the vehicle, reducing blind spots, and also alerting pedestrians at the rear.

What Causes the Abnormal Noise When Reversing?

The reasons for abnormal noise when reversing are: 1. Noise caused by the slow speed when reversing; 2. Internal noise from the transmission itself; 3. Noise caused by parts of the clutch system in manual transmission vehicles; 4. Noise from the clutch release bearing or the flywheel pilot bearing; 5. Noise from the manual transmission gear shifting mechanism; 6. Noise due to aging or loose chassis components. Solutions for abnormal noise when reversing: 1. Pay attention to the cleanliness of vehicle components; 2. Engage neutral gear when parked for a long time; 3. Take the vehicle to a 4S store for inspection and repair; 4. Control the speed when reversing; 5. Replace aging components.

What are the steps for driving an automatic transmission car?

The steps for driving an automatic transmission car are: 1. Press the brake and start the engine; 2. Shift from P (Park) to D (Drive); 3. Release the handbrake, lift the foot brake, and press the accelerator to move. An automatic transmission means the driver does not need to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The gears in an automatic transmission are: P (Park) - also the starting gear; R (Reverse) - for reversing; N (Neutral) - the neutral gear; D (Drive) - the forward gear, also known as the driving gear; S (Sport) - for sport mode; L (Low) - the low-speed gear. The engine's power is transmitted through the gearbox, which uses planetary gear mechanisms to automatically shift gears based on the degree of accelerator pedal pressure and changes in vehicle speed.

What is the warranty period for airbags?

Airbags generally have a warranty period of around ten years. An airbag system consists of an airbag sensor, collision airbag, and electronic control unit. Airbags can be categorized into single airbag, dual airbag, four airbag, multi-airbag, side airbag, knee airbag, and head airbag. Guidelines for using airbags: 1. Airbags must be used in conjunction with seat belts; 2. Maintain an appropriate distance from the airbag when seated; 3. Do not place objects in front of, above, or near the airbag; 4. Ensure the airbag functions properly for safety; 5. Avoid high temperatures; 6. Do not modify the airbag system or its surrounding configuration without authorization; 7.

What is the Principle of a Car 360-Degree Panoramic Camera?

The principle of a car 360-degree panoramic camera is: through four 180-degree wide-angle cameras installed on the front, rear, left, and right sides of the vehicle, simultaneously capturing images around the car. These images are then corrected and stitched together by an image processing unit to form a 360-degree top-down panoramic view of the vehicle's surroundings, which is transmitted in real-time to the display device on the central console. Features of the 360-degree panoramic camera: 1. Assists in parking; 2. Expands the field of vision when passing through narrow roads or encountering oncoming traffic; 3. Allows the driver to make timely corrections to the driving path via the central console. Installation method of the 360-degree panoramic camera: 1. Debug the device properly; 2. Determine the installation positions, fixing the front and rear cameras with screws; 3. Install the left and right cameras below the rearview mirrors; 4. Adjust the monitoring angles of the cameras.
