Brake pads grinding against brake discs can occur due to the following reasons and solutions: 1. Foreign objects between the brake pads and brake discs: If there were no initial abnormalities but sudden grinding occurs, this is likely the cause. For example, small stones may get caught between the brake pads and discs when braking. Solution: Remove the foreign objects between the brake pads and discs. 2. Material issues: The brake pads or discs themselves may be problematic. If the brake pads are of poor quality, they may have large metal particles on the surface, which can cause grinding. 3. Objective factors: Such as inconsistent friction block sizes of the brake pads or improper installation. If inspection reveals localized friction marks on the brake pads, this can usually confirm the cause. Solution: Reinstall the brake pads properly.

What is the normal power generation for Volkswagen Tiguan?

Volkswagen Tiguan's power generation is considered normal at 13.5 or 14.5. Tiguan Battery Introduction: The normal voltage range for the Tiguan battery before starting is between 11.8V and 12.8V, and it should not exceed 14V after starting. The Volkswagen Tiguan uses a Varta battery model 6-QW-60(580)-L. If the battery shows signs of power loss or leakage, it should be replaced; otherwise, it may result in the vehicle failing to start or the in-car electrical loads losing power. Battery Issues Introduction: When the ammeter indicates insufficient charge, the battery should be recharged promptly. If you find the battery charge insufficient during a trip and the engine cannot be started, as a temporary measure, you can seek assistance from another vehicle to jump-start your car by connecting the negative terminals and positive terminals of the two batteries respectively. When the electrolyte level is low, distilled water or a dedicated replenishment fluid should be added. Never use drinking purified water as a substitute, as it contains various trace elements that can adversely affect the battery. Continuously using the starter when starting the car can lead to battery damage due to excessive discharge.

What are the reasons for failing the slope test in Subject 2?

Excessive nervousness during the test, unfamiliarity with the test site, excessive speed, and carelessness can all lead to failure in the Subject 2 driving test. For beginners learning to drive and taking the license test for the first time, there are always some differences between the practice area and the actual test site. Therefore, it is important to communicate more with the instructor during training to understand the differences between the test site and the practice area.

Can the Subject 1 Test Be Taken on Saturdays and Sundays?

Subject 1 tests cannot be taken on Saturdays and Sundays. Below is relevant knowledge about automobile driving: Interpretation of water temperature gauge readings: The pointer reaching 90 degrees is normal. Generally, the pointer reaches 90 degrees after driving for 5-10 minutes. If the water temperature gauge reading is too high (warning light on), it may cause the radiator to boil over, leading to engine malfunction. If the water temperature is too high or rises too rapidly, stop the engine immediately. After the vehicle's radiator has cooled down, add mineral water or tap water. If the issue persists after restarting the vehicle, contact roadside assistance. Note: As high water temperature may cause radiator spray, never open the radiator cap immediately. If urgent opening is required, it is recommended to cover the radiator cap with a wet towel and turn it counterclockwise to open. Interpretation of fuel gauge display: F indicates full tank, E indicates insufficient fuel. Note: 1. After the fuel tank warning light comes on, the vehicle can generally run for 40-50 kilometers. 2. It is recommended not to keep the fuel tank below 1/3 for a long time, otherwise the fuel pump is prone to damage and wear.

Do Children Count as Overloading in a Car?

Children in the car are considered overloading as long as the number exceeds the approved passenger capacity. Overloading of passenger vehicles is calculated per person, and exceeding by even one, whether an adult or a child, constitutes overloading. Overloading can result in fines ranging from 500 to 2000 yuan and a deduction of 6 to 12 points from the driver's license. Below is an introduction to vehicle overloading: 1. Traffic Safety Law Provisions: According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," traffic management authorities impose administrative penalties on drivers for road traffic safety violations and implement a cumulative scoring system (hereinafter referred to as scoring) for such violations, with a scoring cycle of 12 months. 2. Penalties for Overloading: If a driver accumulates 12 points within a scoring cycle, the traffic management authorities will confiscate their driver's license. The driver must then participate in road safety laws and regulations training and pass an exam. If the exam is passed, the points are cleared, and the license is returned. If failed, the driver must continue training and retake the exam. If a driver does not accumulate 12 points within a cycle and has paid all fines, the points are cleared. If fines remain unpaid, the points carry over to the next cycle.

Is the headlight turned on in Subject Three the low beam?

Headlights refer to the vehicle's high beam, low beam, and turn signals, with the low beam being a part of the headlights. When using a car, the requirements for headlights are: They must provide good illumination while avoiding dazzling oncoming drivers. Keep the headlight lens clean: Especially when driving in rain or snow, dirt and grime can reduce the headlight's illumination performance by up to 50%. Some vehicle models are equipped with headlight wipers and washers. When two vehicles meet at night: Both vehicles should switch from high beam to low beam when they are 150 meters apart to ensure driving safety. To maintain the performance of the headlights: After replacing the headlights or every 10,000 kilometers driven, the headlight beam should be checked and adjusted. Regularly inspect the bulbs, wiring sockets, and grounding for oxidation or looseness: Ensure that the connectors have good contact and the grounding is reliable. If the connections are loose, turning on the headlights may cause current surges due to circuit interruptions, which can burn out the filaments. If the connections are oxidized, the brightness of the bulbs may decrease due to increased voltage drop at the connections.

Where is the trunk switch located on the old Audi A6?

Audi A6's trunk switch is located in the middle of the rear license plate. The specific position is inside the groove right below the four rings.

Press and hold the "car logo" button in the center of the remote key for 3 seconds (the one between the unlock and lock buttons), and the trunk will automatically unlock, but it won't open directly. You still need to lift it manually. Open with the mechanical key: There is a keyhole above the license plate. Insert the key, turn it to unlock, and then lift the trunk lid. Press the unlock button directly: Press the unlock button directly (in the middle of the rear license plate), and the trunk will also unlock and open. Precautions for using the trunk: Be cautious when closing the trunk lid to ensure no one is between the lid and the trunk to avoid injury. After closing the trunk lid, check whether it is properly closed and locked to prevent the lid from suddenly opening while driving. The closed trunk lid should be flush with the surrounding body.
