Why is the Volkswagen rearview mirror heating not working?

If the rearview mirror heating in a Volkswagen is not functioning, the first thing to consider is whether the outdoor temperature is too high. If the temperature is not the issue and the rearview mirror heating still doesn't work, it is advisable to seek timely inspection and repair. The rearview mirror heating function refers to the ability of the rearview mirror to be heated via electric heating wires embedded behind the mirror when driving in rainy, snowy, or foggy weather, ensuring a clear mirror surface. Below is an introduction to the rearview mirror heating function: 1. Suitable conditions: The rearview mirror heating is most useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog from the mirror, eliminating the need for the driver to manually wipe the mirror frequently, thereby reducing driving hazards. 2. Principle: An electric heating element (heating film) is installed inside the mirror of both rearview mirrors. In rainy or snowy conditions, when the driver activates the rearview mirror heating function, the heating element rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius, thereby heating the mirror to remove fog and frost.

Can a Water-Damaged Car Still Be Used?

If a vehicle has been waterlogged, it is recommended not to drive or use it anymore. Below is extended information about the hazards of water-damaged cars: 1. The electronic control system inside the car: The mixed rainwater is highly corrosive and can affect the functionality of electrical components, especially impacting future use. Since most cars are equipped with electronic control systems (such as the engine ECU, ABS system, SRS system, GPS navigation, etc.), if water enters, it can cause short circuits in the ECU's internal IC circuit board and rust spots on connector terminals. This gradually leads to corrosion of metal parts, resulting in poor contact in circuits and even short circuits that may cause burning. 2. The engine: The engine connecting rod may deform, causing the piston stroke to shorten, which prevents gases from being fully compressed. The piston rings may lose elasticity or fail to seal properly, leading to gas leakage. Compressed gas may escape into the crankcase. If the intake and exhaust valves do not seal properly when closed, compressed gas may leak into the intake and exhaust manifolds.

What are the wrong practices when a vehicle has a tire blowout?

When a vehicle experiences a tire blowout, the wrong practices are jerking the steering wheel and slamming on the brakes. When encountering a sudden tire blowout at high speed, the first thing to do is to grip the steering wheel firmly with both hands to stabilize the direction, followed by controlling the braking force to gradually reduce the speed. For manual transmission or semi-automatic vehicles, forced downshifting can be used to decelerate with the engine. Consequences of jerking the steering wheel and slamming on the brakes during a tire blowout: Drivers often attempt to steer to control the vehicle direction during a blowout, unaware that the direction is largely uncontrollable at that moment. Jerking the steering wheel can cause the vehicle to lose control, leading to a high risk of skidding. Slamming on the brakes during a blowout can also lock up the already uncontrollable tires, resulting in loss of steering control and increasing the likelihood of collisions with guardrails or nearby vehicles. Summer tire blowout prevention tips: High summer temperatures cause tire temperatures to rise, softening the rubber and potentially leading to tire overheating or even burning. Driving at high speeds over hard objects can easily cause a blowout. Regularly check tire pressure while driving. If the tires are overheated or the pressure is too high, park the vehicle in a shaded area to cool down. Avoid dousing with cold water or releasing air, as these actions can lead to blowouts during travel and premature tire damage.

What are the new extended warranty regulations for the 12 Focus transmission?

The extended warranty period for the 12 Focus transmission is five years. Methods to determine when transmission fluid needs replacement: 1. Replacement cycle: According to the transmission fluid replacement cycle, transmission fluid should be replaced every 40,000 to 60,000 kilometers. Manual transmission fluid should be replaced every 60,000 kilometers, while automatic transmission fluid should be replaced every 40,000 to 60,000 kilometers. 2. Fuel consumption: If you experience increased fuel consumption, slow acceleration, or delayed gear shifting while driving, it is recommended to perform maintenance. 3. Transmission: When transmission fluid contains a significant amount of iron particles and debris, the lubrication performance of the transmission will noticeably decline, leading to severe transmission wear. Generally, vehicles that exceed 100,000 kilometers without maintenance will exhibit this condition, so replacement is recommended.

What is the wading depth of the Fengjun 7?

The wading depth of the Fengjun 7 is 400mm. The wading depth of the Fengjun 7 is determined by the height of the vehicle's chassis, which is the ground clearance listed in the model's parameter configuration table. Generally, the greater the ground clearance, the higher the chassis, and the higher the safety factor when driving through waterlogged roads. Therefore, in terms of safe wading depth, off-road vehicles and SUVs have obvious advantages. However, for most compact and small cars with low chassis, the position of the vehicle's air intake should be used as a reference when passing through waterlogged roads. If the air intake of the Fengjun 7 is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it will cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth should not exceed the height of the engine's air intake. The height of the engine's air intake, and thus the maximum wading depth, can also be increased by installing a snorkel. If wading is unavoidable, the following safe and correct operations should be performed: Before wading, always turn off the auto start-stop function to prevent the vehicle from automatically restarting after stalling in water, which could cause severe engine damage due to water ingress. Assess the underwater road conditions based on the passage of vehicles ahead and choose an appropriate entry point. Observe the path taken by other vehicles and follow their tracks at low speed, avoiding sudden acceleration or deceleration. On roads prone to water accumulation, observe warning water level markers, trees, and other reference points such as the wheels and doors of other vehicles to estimate the water depth before deciding whether to proceed. Know your vehicle's safe wading depth. If the water depth exceeds half the height of the tires or the engine's air intake, do not attempt to drive through. Instead, choose an alternative route.

Does keeping the automatic parking in D gear damage the car?

Keeping the automatic parking in D gear can damage the car. When the automatic parking is engaged in D gear, the engine remains in an idle state. If this condition persists for an extended period, the temperature of the transmission will continuously rise, which can easily cause the transmission fluid to deteriorate, accelerate transmission wear, and reduce its service life. More details are as follows: Usage of automatic parking: Automatic parking relies on the intelligent braking system and can only be used in vehicles equipped with brake control systems such as ESP. Automatic braking function: The automatic parking function can be understood as an automatic braking feature, which is very convenient to use. Once activated, simply pressing the brake pedal will engage the parking brake, preventing the vehicle from rolling. In this state, there is no need to change the gear, enhancing parking safety.
