Audi's headlights and fog lights are turned on in the same way across all models. Taking the domestic Audi A4L as an example, the switch is located below the air vent on the driver's side. The middle knob controls the width lights and low beams, while the two buttons on the left, arranged vertically, are for the front and rear fog lights—simply press them to activate. The right side features controls for the interior lights and instrument panel brightness adjustment. The purpose of fog lights is to make the vehicle visible to others in conditions of reduced visibility, such as fog or heavy rain. Therefore, fog light sources need strong penetration. Most vehicles use halogen fog lights, while more advanced models may feature LED fog lights. Fog lights must be installed below the bumper, as close to the ground as possible, to ensure their effectiveness. If positioned too high, the light cannot penetrate the fog or rain to illuminate the road (since fog is usually thinner below 1 meter), which could lead to hazardous situations. Typically, fog light switches have three positions: the 0 position is off, the first position controls the front fog lights, and the second position controls the rear fog lights. When set to the first position, only the front fog lights are on; at the second position, both front and rear fog lights operate. Therefore, when turning on the fog lights, it's advisable to know which position the switch is in, ensuring convenience for yourself and safety for others on the road.

What to do with ETC when changing license plates?

The method to handle ETC when changing license plates: 1. Remove the ETC reader from the original vehicle; 2. Bring the ETC card, original ID card, new vehicle registration certificate, and relevant documents for both the old and new vehicles to the bank branch where the ETC card was issued to complete the transfer procedures; 3. Contact ETC personnel to reinstall the device, input the new license plate information, and perform installation and scanning activation. ETC is an electronic toll collection system that uses a vehicle-mounted electronic tag installed on the windshield to communicate with microwave antennas in ETC lanes at toll stations via dedicated short-range communication. It leverages computer networking technology for backend settlement with banks, allowing vehicles to pass through highway or bridge toll stations without stopping to pay fees.

Why is there a strong smell of gasoline when starting the car?

The reason for the strong smell of gasoline when starting the car is: the gasoline is not completely burned. When the car starts while cold, the onboard computer will appropriately increase the fuel injection based on the intake air temperature and coolant temperature signals. At this time, the engine has not yet reached its normal operating temperature, resulting in poor combustion efficiency. This causes some fuel to be expelled without being fully burned, leading to a strong gasoline smell when starting the car. In older cars, the rubber hoses in the engine compartment are prone to aging, which can cause leaks. If you notice a strong gasoline smell when starting the car and the smell persists, you should check the condition of the fuel lines. If the strong gasoline smell remains after the car has been running for a while, it indicates a malfunction. Common issues include insufficient air intake through the throttle, which leads to incorrect air flow information affecting the fuel injection amount, resulting in a heavier gasoline smell.

Can China II vehicles still be driven in Beijing?

China II vehicles are not allowed to enter within Beijing's Fifth Ring Road, but they can still be driven during certain specific time periods. Since 2019, many cities have begun implementing the China VI emission standards. After the implementation of the China VI emission standards, many China II and China III vehicles have also been subject to driving restrictions. The implementation of strict emission standards by the state can constrain automakers and encourage them to produce more environmentally friendly vehicles, which is beneficial for protecting the Earth's environment. Initially, the China VIa standard was implemented, and it is expected that the China VIb standard will be implemented by 2023. The China VIa standard stipulates: 1. Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven; 2. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven; 3. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven; 4. Gasoline vehicles must not emit more than 4.5 milligrams of PM fine particles per kilometer driven.

Why does the car shake when starting?

The reasons why the car shakes when starting are: 1. The throttle is dirty or the fuel injector has excessive carbon deposits. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an excessively lean mixture for cold start, making it difficult to start and causing idle shaking after cold start; 2. Poor working conditions of the ignition system and spark plugs can also lead to such fault phenomena; 3. If the engine carbon deposits have been cleaned, the throttle has been washed, and the spark plugs have been replaced, but the car body still shakes at idle, it is recommended to check whether the fuel supply pressure and the intake pressure sensor are normal. Abnormal fuel pump supply pressure or incorrect values and poor working conditions of the intake pressure sensor can also cause the car body to shake.

What is Automotive Chassis Armor?

Automotive chassis armor is a high-tech adhesive rubber asphalt coating that protects the vehicle's chassis during operation, preventing damage from sand and stones, and also avoiding rusting of the chassis during use. Automotive chassis armor features non-toxicity, high coverage, and strong adhesion. The functions of automotive chassis armor include: 1. Impact resistance: During driving, flying gravel can hit the chassis, causing significant damage over time; 2. Undercarriage protection: Protrusions on different road surfaces can wear down the chassis; 3. Corrosion prevention: In regions with frequent rainy seasons, such as southern areas, acid rain can easily splash onto the chassis, leading to corrosion; 4. Heat insulation: In summer, high ground temperatures can cause heat to transfer from the chassis into the vehicle.
