Is it okay to shift to P gear after the car is turned off?

For automatic transmission vehicles, it is possible to shift to P gear after turning off the engine. However, many car models are factory-set to require shifting to P gear before the engine can be turned off; otherwise, the engine won't shut down. For automatic transmission cars, when parking and turning off the engine, the principle is to ensure that the handbrake is engaged, and it must be engaged before shifting to P gear. Here is an introduction about parking: 1. Theoretical parking operation for automatic transmission: First reduce the speed to zero, then shift to neutral, engage the handbrake, and finally shift to P gear. 2. P gear (Parking): Used for parking. It utilizes a mechanical device to lock the rotating parts of the car, preventing the vehicle from moving. When the car needs to remain stationary for an extended period or before leaving the vehicle after parking, the handbrake should be engaged, and the gear lever should be moved to the "P" position. 3. Important notes: The vehicle must be completely stopped before using P gear; otherwise, the mechanical parts of the automatic transmission may be damaged. Additionally, automatic transmission vehicles are equipped with a neutral start switch, ensuring the engine can only be started in "P" or "N" gear to prevent accidental starts in other gears that could cause the car to lurch forward unexpectedly.

What Does Vehicle Damage Assessment Mean?

Vehicle damage assessment refers to the insurance claim damage assessment, which is a crucial step in the claims process. Key considerations for vehicle damage assessment and claims: 1. Determine the repair method in advance: When certain parts of the vehicle are damaged, disagreements may arise between the policyholder and the assessor regarding whether the parts should be replaced or repaired. Generally, insurance companies prefer repairing damaged parts over replacement. If a damaged part cannot be repaired, it may be replaced. Therefore, it is advisable for the policyholder to discuss and confirm the repair method with the assessor before or during the repair process to ensure proper compensation. 2. Negotiable assessment amount: Apart from disputes over repair methods, disagreements over repair costs are common in vehicle damage assessments. A frequent scenario is when the repair shop quotes a higher repair cost than the amount assessed by the insurance adjuster. Typically, adjusters determine reasonable repair costs based on market prices. However, repair shops may charge higher prices due to procurement channels or other reasons. In such cases, if the policyholder disagrees with the assessed amount, they can communicate with the adjuster, who will then negotiate with the repair shop. 3. Conduct assessment and repairs at the same location: In addition to the above points, if the policyholder has already agreed with the surveyor to assess damages based on a 4S shop's repair standards, they should not proceed with repairs at a regular repair shop. Since 4S shops charge higher repair costs than regular repair shops, paying the 4S shop's assessed amount at a regular repair shop would result in higher expenses for the policyholder. During claims, the insurance company will reassess the damages based on the actual repair shop chosen by the policyholder, potentially leading to unnecessary financial burdens for the vehicle owner.

What are new energy vehicles called in Japan?

New energy vehicles are also referred to as new energy vehicles in Japan. However, in Japan, the vast majority of new energy vehicles are basically pure electric vehicles. In China, new energy vehicles not only include pure electric vehicles but also plug-in hybrid vehicles. Below is an introduction to new energy vehicle brands: 1. Some of the better brands for new energy electric vehicles include Tesla, NIO, ORA, BAIC, and BYD. New energy electric vehicles operate more quietly, with electric motors free from excessive vibrations and noise. Additionally, new energy electric vehicles are more environmentally friendly as they produce no exhaust emissions. 2. Tesla is the most mature electric vehicle manufacturer and a leader in the popularization of new energy pure electric vehicles. Headquartered in Palo Alto, Silicon Valley, California, USA, the company currently offers the following electric vehicle models: Model S, Model X, Model 3, Model Y, and Roadster. 3. BYD has consistently maintained a leading position in the pure electric vehicle sector. Currently, BYD's pure electric vehicle models include: BYD ES5, E1, E6, Qin EV, Song EV, Tang EV, E2, and E-SEED-GT.

Does exceeding the recommended maintenance mileage affect a car?

The impacts of exceeding the recommended maintenance mileage for a car: 1. If the engine oil exceeds the maintenance mileage by too much, it will reduce the oil's fluidity, thereby increasing engine wear. In severe cases, it may cause issues such as unexplained engine stalling, especially affecting turbocharged engines more significantly. 2. If the coolant exceeds the maintenance mileage by too much, it can lead to frequent high-temperature warnings for the engine. Additionally, the cooling system is more prone to scale buildup, resulting in poorer engine cooling performance. 3. Exceeding the maintenance mileage for the braking system can cause the brake fluid to lose effectiveness. Prolonged braking will raise the temperature of the brake fluid, lowering its boiling point, and after boiling, the braking system will become ineffective.

What to Do When Car Window Glass is Difficult to Raise or Lower?

Reasons and solutions for difficult window glass operation: 1. Window lift motor damage or poor contact in the wiring harness: If there is a burnt smell when holding down the window button or strange noises inside the door panel, it is likely that the window lift motor components are damaged. In this case, it is recommended to directly replace the window lift motor. 2. Motor overheating protection: To protect the power supply circuit, most window lift motors have an overheating protection mechanism. If components overheat for some reason, the motor will enter a protection state, causing the window to stop functioning. In this situation, simply wait for the motor to cool down. 3. Excessive resistance in the glass guide channel: The door glass guide channel is an often-overlooked detail. Over time, dust can accumulate in the guide channel, increasing resistance and making it harder to raise the glass. Regularly clean debris from the window glass guide rails or use lubricating grease for lubrication. 4. Loss of computer data: Disconnecting the battery, interrupting power or ground lines to the window control module during maintenance of other systems, or severe power loss when starting the engine can cause the initialization data for the windows to be lost, preventing them from operating. In this case, the window lift function needs to be reset.

How Long Does It Take to Replace Brake Pads?

Replacing a set of brake pads alone takes about 1 hour, which is both time-consuming and labor-intensive. The specific steps are as follows: 1. When replacing brake pads, the car needs to be lifted and the tires removed. 2. Remove the screws of the brake caliper, take off the brake caliper, and remove the old brake pads. 3. Push the brake piston back in and install the new brake pads. 4. Reinstall the brake caliper, tighten the caliper screws to the required torque, and then reinstall the tire. Precautions: 1. After replacing the brake pads on both sides, you may notice brake fluid overflowing from the brake fluid reservoir. In this case, you need to press the brake pedal several times to keep the fluid level between max and min. 2. Pressing the brake pedal is to eliminate the gap between the brake pads and the brake disc and to reset the wheel cylinder piston. 3. Generally, new brake pads require a break-in period. Only after this period can they perform their braking function more effectively.
