Does driving a car in water without stalling have any impact on the vehicle?

There is basically no impact. Since water pressure is much lower than the exhaust pressure of the cylinders, as long as the vehicle does not stall, water will not flow back into the engine, so there will be no effect. Correct methods for driving through water: 1. If the car stalls in water, do not attempt to restart it immediately. Stalling in water can cause the engine to take in water, and after stalling, the car should only be towed to a repair shop in neutral gear for cleaning. 2. The water depth for small cars should not exceed 40 cm. The maximum wading depth varies among different vehicle models; generally, off-road vehicles can handle about 60 cm, while small cars should not exceed 40 cm. If observation shows that the water level is high, it is advisable to detour rather than force passage. 3. Do not accelerate when driving through water. You should maintain a steady speed with low gear and moderate to high throttle, rather than speeding through and splashing water. High speed can increase the actual depth of water the car passes through, causing rainwater to enter the cabin from the engine compartment or chassis.

Where is the brake located?

According to the different installation positions on the vehicle, parking brake devices are divided into two types: central parking brake devices and wheel parking brake devices. The brake of the former is installed on the transmission shaft, called the central brake; the latter shares a set of brakes with the service brake device and is installed on each wheel hub. The four parts of the wheel brake are as follows: 1. Brake wheel cylinder: The function of the brake wheel cylinder is to convert the hydraulic energy input from the brake master cylinder into mechanical energy to put the brake into working condition. 2. Brake caliper: When braking, the brake fluid flows from the brake master cylinder through the brake pipe into the brake caliper, and the brake fluid pushes the caliper to press the brake pads, thereby stopping the vehicle. 3. Brake disc: It rotates when the vehicle is moving. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the vehicle. 4. Brake pads: The working principle of braking mainly comes from friction. The kinetic energy of the vehicle's movement is converted into heat energy after friction by using the friction between the brake pads and the brake disc (drum) and the friction between the tires and the ground, thereby stopping the vehicle.

Is it necessary to apply for a highway ETC card?

It is necessary to apply for an ETC card. According to the regulations of the State Council, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they need to be activated before normal use. During free holiday periods, vehicles with ETC can still use highways, and ETC users passing through ETC lanes will not be charged. ETC charging principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the purpose of paying tolls without stopping at road and bridge toll stations is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Green and low-carbon, vehicles passing through toll stations without stopping can reduce noise and exhaust emissions, minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The efficiency of ETC lanes can theoretically increase by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interconnection of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will significantly increase." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, efforts will be made to promote ETC usage for trucks in the future. There will also be exploration of deep integration between ETC systems and smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.

Why does the car still not move when the handbrake is released?

When the car's handbrake is released but the rear wheels remain locked, it can be caused by several reasons. Possible causes include a frozen handbrake cable, frozen brake friction pads, damaged brake calipers, brake pads and rotors bonding due to water exposure, or a rusted and stuck handbrake cable. Here are some methods to prevent freezing, rusting, or failure: 1. In extremely cold winter conditions, avoid using the handbrake; manual transmission cars can be left in first gear, while automatic transmission cars can be put in P (Park) mode. 2. After driving in rainy weather or after car washes, press the brake pedal several times to generate friction heat and evaporate moisture. 3. Regularly maintain your vehicle, as technicians will inspect the braking system for any potential issues.

Reasons for Simultaneous Illumination of Audi ABS and Anti-Skid Warning Lights

The issue is caused by a malfunction in the vehicle's anti-skid system. Below are detailed explanations: 1. ABS System Malfunction: When the ABS system fails, the vehicle can still rely on conventional braking. If both the ABS warning light and brake system warning light illuminate simultaneously while driving, it indicates failures in both ABS and conventional braking systems. 2. Anti-Skid System Failure: When the vehicle's anti-skid system malfunctions, promptly visit an authorized 4S dealership or repair shop for inspection and maintenance to resolve the simultaneous illumination of ABS and anti-skid warning lights. It is advised not to continue driving when ABS fails, or alternatively, cautiously proceed to an auto repair shop using conventional braking at reduced speed, avoiding aggressive maneuvers. A faulty anti-lock braking system may also affect the ESP anti-skid system. Anti-skid system failure can lead to dangerous skidding during emergency braking or sharp turns.

Can Electromagnetic Suspension Be Installed Afterwards?

Electromagnetic suspension is an original factory option, and 4S stores do not have the capability to install it, so it cannot be installed afterwards. Below is relevant information about automotive electromagnetic suspension: 1. Advantages of electromagnetic suspension: The device has a simple structure, extremely low power consumption, a wide range of controllable stress, and can achieve instantaneous precise control of damping force. It is also insensitive to impurities, has a wide working temperature range, and can operate between -50°C and 140°C. Electromagnetic suspension can be directly powered by a common low-voltage power source (such as a standard battery), avoiding the dangers and inconveniences associated with high-voltage power. Compared to traditional automotive shock absorbers, it has significantly fewer moving parts, almost no collisions, resulting in low noise. 2. Function of electromagnetic suspension: Vehicles equipped with electromagnetic suspension can increase tire contact with the ground even on the most rugged roads, reduce tire rebound, control the vehicle's center of gravity shift and pitch, maintaining vehicle stability. It also effectively controls body sway during sharp turns or evasive maneuvers.
