Is Detailing and Waxing Harmful to Car Paint?

Why is the Lexus reversing radar not beeping?

There may be three reasons: whether the radar host wire is loose; the buzzer is damaged; or the wiring at the bumper is damaged. Here are the detailed explanations: 1. Whether the radar host wire is loose: If you find that the reversing radar is not beeping, first check whether the power cord of the host is properly connected and whether there is current; then check whether the radar host wire is loose. If neither of these is the problem, the issue may lie with the radar itself. 2. Buzzer damage: If the problem is confirmed to be with the reversing radar, the first possibility to consider is that the buzzer is damaged. In this case, you need to purchase and install a new buzzer; also, recall whether your car has undergone any recent modifications. If so, it is possible that the reversing radar wiring was damaged during the modification process. In this case, you need to take the car to the original repair shop or a 4S store for inspection. 3. Wiring damage at the bumper: When you find that the reversing radar is not beeping, you can also check whether the wiring connection at the bumper is intact, then check whether the reversing light is on when the reverse gear is engaged. If it is not on, check whether the connection switch of the reversing light is broken. Then, you can check whether the computer displays any fault codes. If none of these is the problem, then check whether the reversing radar itself is malfunctioning.

What happens when an electric vehicle battery gets wet?

There are three main impacts when an electric vehicle is submerged in water: 1. Although the motor controller is designed to be waterproof, its water resistance is usually not particularly good. Water entering the controller may directly cause it to burn out. 2. If water enters the motor, it can cause a short circuit at the connection points, especially in cases of deep water submersion. 3. Water entering the battery compartment can directly cause a short circuit between the positive and negative terminals. The mild consequence is battery damage, while the most severe consequence could be the battery burning out or even exploding. Precautions after an electric vehicle gets wet: 1. Allow the battery to dry before charging. If the electric vehicle battery gets wet from rain, do not charge it immediately. Instead, place the vehicle in a ventilated area to dry before charging. 2. A wet controller is prone to short circuits and loss of control. Water entering the controller of an electric vehicle can easily cause the motor to reverse. After severe submersion, the owner can remove the controller, wipe out any accumulated water, and use a hairdryer to dry it thoroughly before reinstalling it.

What is the Normal Fuel Consumption per 100 Kilometers for Sedans?

Different vehicles, models, engine displacements, and driving habits result in varying fuel consumption. Generally, for household sedans with around 1.6-liter engine displacement, the fuel consumption per 100 kilometers is approximately 6-8 liters. Depending on driving habits, it may be slightly higher. Road conditions also play a role; for instance, fuel consumption tends to be higher in congested urban areas. Below are detailed insights: 1. Fuel Consumption Level: Although the fuel consumption per 100 kilometers varies by vehicle, you can gauge what's appropriate for your engine. As mentioned, exceeding 7.5L in urban areas is considered relatively high fuel consumption. Therefore, this figure is quite normal. 2. Driving Habits: When driving, it's advisable to maintain a steady speed, avoid sudden acceleration and braking, and minimize unnecessary overtaking. To improve fuel efficiency, the first step is to adjust your driving habits.

Can I Drive with a Photo of My Driver's License?

Forgetting to bring your driver's license does not constitute driving without a license. You can use a photo of your driver's license or provide your ID information to look up the license number. If you forget to bring your driver's license while driving, it is considered "not carrying the license" rather than "driving without a license." Traffic police will not detain the individual but will temporarily impound the vehicle. Below are the relevant regulations: 1. According to Articles 95 and 90 of the Road Traffic Safety Law, the handling of not carrying a driver's license is as follows: Regardless of whether the driver has violated traffic laws while driving, they are not allowed to continue driving, and the traffic management department of the public security organ shall impound the motor vehicle and require the driver to provide the driver's license. 2. Depending on the situation of the driver providing the license, the following actions will be taken: If the driver provides the license and has no other violations while driving, they will be given a warning or fined, and the vehicle will be promptly returned; if the driver provides the license but has committed other violations while driving, they will be penalized based on the violations and for not carrying the license, and the vehicle will be promptly returned; if the driver fails to provide the license, they will be penalized for driving without a license.

Will a Large Hood Gap Cause Water Intrusion?

Yes, a large hood gap can allow water intrusion, but it does not affect the vehicle's usability. From the factory, hood gaps are normal, as the front of the engine is equipped with drainage mechanisms to prevent electrical issues. Manufacturers account for this during production. Below are related details: Disadvantages of a large hood gap: It can increase driving vibrations, look unattractive, and allow rainwater to leak into the engine compartment. Adjustments can be made to reduce the gap. Purpose of the hood: Air resistance and turbulence around moving objects affect trajectory and speed. The hood's design helps manage airflow direction and resistance, minimizing its impact on the vehicle.

How to Determine if a Car Tire is Underinflated?

Methods to determine if a tire is underinflated include: 1. Visually inspect if any of the four tires appears noticeably flat. 2. Use a tire pressure measurement device, such as a handheld tire pressure monitor or an onboard automatic tire pressure display, to accurately measure the tire pressure. 3. Install a tire pressure monitoring system to continuously monitor the tire pressure. Here are the effects of underinflated tires: 1. Damage to the tire sidewall and inner edge: Damage to the inner edge of the tire is usually caused by improper operation during mounting or dismounting the tire from the wheel rim. This often occurs during the installation of new tires or after tire repairs. Damage to the sidewall and inner edge can lead to slow leaks and a high risk of tire blowouts. 2. Foreign objects puncturing the tire: Punctures from foreign objects are the most common type of tire damage. Objects that easily puncture tires include nails, screws, wires, glass shards, sharp stones, and ceramic fragments. Among these, nails and screws are the most likely to puncture the tire, causing slow leaks. If left unaddressed, these objects can worsen the damage to the tire. 3. Deformation of the wheel rim flange: When a car tire is fully inflated, the outer edge of the tire tightly seals against the wheel rim flange to prevent gas leakage. If the wheel rim flange is deformed due to impact, it can compromise the seal with the tire's outer edge, leading to slow leaks.
