Why is the remote control distance of the car key fob short?

The short remote control distance of a car key fob is not only related to the transmitter, battery level of the key, and the car's receiving antenna, but also to obstacles around the car such as trees and walls. Additionally, interference from other signals, such as mobile phone signals, signals emitted by other car keys being used simultaneously, and surrounding WiFi signals, can also affect the range. If you notice that your car's remote key has a significantly reduced range, you can try testing it in a different location. The working principle of a car remote key is that it first emits a weak radio wave from the key, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator performs the locking or unlocking action.

How to Solve the Problem of Excessive Noise in Wuling Hongguang S?

Solutions for excessive noise in Wuling Hongguang S: The noise is mainly caused by vibrations from the engine hood and front fenders transmitting into the cabin. Therefore, installing high-quality sound-absorbing foam materials on the engine hood can not only suppress vibrations caused by the hood but also absorb a significant amount of noise. The Wuling Hongguang S is a microvan with dimensions of 4390 mm in length, 1660 mm in width, and 1750 mm in height, and a wheelbase of 2720 mm. In terms of safety features, the Wuling Hongguang S is equipped with dual airbags, force-limiting seat belts, LED high-mounted brake lights, a rear parking sensor, rear window defrosting function, rear wiper, child safety locks on the sliding doors, and an automatic locking function.

What Causes the Antifreeze to Spray Out at High Temperatures?

It is possible that during driving, the high-temperature environment of the engine causes the antifreeze to heat up, reach boiling point, and subsequently overflow. Alternatively, the antifreeze may not be circulating properly due to a malfunctioning thermostat, a non-operational water pump, or a blockage in the coolant circulation system, leading to the antifreeze spraying out. If antifreeze sprays out, it is recommended to pull over and let the engine idle for a while to allow the temperature to gradually decrease. Check if the cooling system is functioning properly and inspect the antifreeze level. Do not turn off the engine immediately, as stopping the cooling fan and coolant circulation will cause the engine to become even hotter. Open the hood to increase airflow and allow the water temperature to drop before removing the radiator cap. Turn it to the first position and wait for the internal steam to escape before fully opening it. Do not add coolant immediately, as boiling water in a sealed container creates pressure. Opening the radiator cap right after boiling can cause the pressurized water to spray out, leading to burns. Afterward, check the radiator hoses for leaks. If the overheating is due to low antifreeze levels, replenish it once the engine temperature has decreased. In emergencies, if antifreeze is unavailable, you can add a small amount of water and proceed to the nearest repair shop for maintenance or replacement.

What to Do When the Key Symbol Appears on the Vehicle?

Solutions for the key symbol appearing on the vehicle: When the key symbol is displayed on the vehicle, it indicates that the vehicle cannot detect the car key. This could be due to a malfunction in the vehicle's receiving module, a failure in the key's transmitting module, or simply a dead battery in the key. In such cases, it is necessary to promptly replace the vehicle's receiving module, replace the key's transmitting module, or change the key's battery. The car's smart keyless entry system utilizes RFID radio frequency technology and a vehicle identity code recognition system. It pioneers the development of a compact, low-power RF antenna solution and successfully integrates remote control and keyless systems while maintaining traditional vehicle circuit protection. This truly achieves a dual RF system and dual anti-theft protection, providing convenience and security for car owners.

Should I go to a 4S shop or a repair shop for tire repair?

Tire repair within the warranty period is more secure at a 4S shop, while auto repair shops may be relatively more affordable, but with varying levels of technical expertise. Below are specific methods for tire repair: 1. Patch repair: This method is more complicated, requiring the use of a tire machine to remove the tire, grind the wound, apply glue, and then stick a patch after the glue dries. It takes less time and is cheaper, but the patch may fall off when exposed to water over time, making it suitable for small and shallow wounds. 2. Mushroom plug repair: This involves inserting a mushroom-shaped rubber plug from inside the tire, locating the wound, threading the mushroom root from the inside out, cutting off the exposed part, and then securing the inner part with special glue. The mushroom root provides an external repair effect, while the top of the mushroom plug acts as an internal repair. This method offers better and more durable repair results, but it is relatively more expensive and time-consuming, making it suitable for larger punctures. 3. Rubber strip repair: This method does not require removing or installing the tire or performing dynamic balancing, making it convenient and quick. However, rubber strip repair involves enlarging the original wound, which can cause some damage to the tire, and may lead to air leakage over time. 4. Hot patch repair: Hot patch repair is similar to patch repair, with the difference being that after applying the patch, a baking machine is used to heat the wound until the patch melts and bonds with the wound. Hot-patched wounds are very durable and are unlikely to leak again. However, hot patching requires strict control of heating temperature and time. If the heating is not properly managed, it may scorch the tire or even cause deformation in severe cases.
