Owners can perform daily maintenance on Audi series models by focusing on the following aspects. 1. Air filter: Squeeze the duckbill-shaped pipe opening by hand to remove impurities from the pipe. 2. Air cleaner: Remove the filter element from the air cleaner and clean out impurities. During reassembly, ensure the sealing of all connections. 3. Wiper and washer system: Regularly check the condition of the wiper blades. Replace them promptly if they do not make proper contact with the windshield. 4. Battery: During maintenance, keep the battery casing dry and clean to prevent leakage. When the fluid is low, do not add electrolyte, mineral water, or tap water. Avoid striking the terminals. 5. Tires: Regularly check if the tire pressure meets the standard. Do not install inner tubes inside the tires or use tires with inner tubes. 6. Vehicle exterior: Avoid dry wiping the car body. Do not use gasoline, kerosene, trichloroethylene, strong alkaline water, or alcohol to clean the paint surface or acrylic surfaces. When using a high-pressure washer, do not spray directly at the transmission, steering mechanism, radiator, or engine compartment. Do not scrape off asphalt stains on the car body or bumper, and avoid using gasoline or fabric to remove dirt.

I've been driving an Audi A4 for several years and have developed some regular maintenance habits. Changing the engine oil and oil filter every six months or 7,500 kilometers keeps the engine running smoothly. Before starting the car, I quickly check the tire pressure and lights to avoid unexpected issues. When washing the car, I also inspect the body for scratches and address them promptly to prevent rust—waxing after each wash helps protect the paint. I pay special attention to the braking system, replacing the brake fluid every two years or so to prevent failure, and changing the cabin air filter in summer to keep the air fresh. Don’t forget to replace the coolant and power steering fluid regularly as well. Although it costs a bit more, taking the car to the dealership for professional inspections helps detect potential issues early, ensuring smooth and reliable performance. These details have kept my car running well and worry-free for years, and friends often compliment its well-maintained condition.

What are the timed items in Subject 2?

Parallel parking and reverse parking are timed, with the timer starting when the vehicle reaches the starting point of these maneuvers. Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. For small vehicles (C1, C2), the test items include five mandatory components: reverse parking into a garage, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-turns). Below are some important notes for the Subject 2 test: 1. Fasten your seatbelt: Always buckle up immediately after getting in the car. Make sure not to fasten it backward or to the passenger seat, as the system will directly deem the test as failed. Do not unfasten the seatbelt during the entire test. 2. Adjust the seat and mirrors: After entering the vehicle, adjust the seat and mirrors, fasten the seatbelt, turn on the left turn signal, shift into first gear, and release the handbrake. These six steps are essential. Ensure all preparations are complete before starting. 3. No stopping during the test: There is no time limit for reverse parking, but it is crucial not to stop during the maneuver. If the wheels remain stationary for 3 seconds, the system will judge it as an intermediate stop. Therefore, controlling the speed is key. 4. The time limit for starting on a slope is 30 seconds: The system will provide an audio reminder every 10 seconds during the 30-second period for starting on a slope. Exceeding this time will result in an automatic failure.

Is It Dangerous to Leave a Lighter in the Car?

Dangerous. Leaving a lighter in the car can cause an explosion. Here are the details: 1. Reason: Lighters are filled with gas. Placing a lighter on the dashboard or instrument panel makes it prone to direct sunlight. After prolonged exposure to sunlight, the gas inside the lighter will continuously expand. Once it reaches a critical point, an explosion can occur, causing severe damage to the vehicle. 2. Precautions: During summer, try to avoid leaving lighters in the car as it poses significant safety risks. The main component of a regular lighter is liquid butane. High concentrations of butane can explode at room temperature of 20 degrees Celsius. If the outdoor temperature exceeds 30 degrees Celsius, the temperature inside the car can rise to 60-70 degrees Celsius after being exposed to sunlight, making lighters highly prone to causing explosion accidents. If a lighter self-detonates due to intense sunlight exposure, it is considered human-caused damage to the vehicle, and insurance companies will not cover the compensation.

Should the front wheels cross the yellow line in the parallel parking test for Subject 2?

The front wheels should cross the line. Below is a relevant introduction about Subject 2: 1. Key points to note: Adjust the seat and rearview mirrors to your preferred position and fasten the seatbelt. Pay attention to controlling the vehicle speed (mainly by adjusting the clutch pedal height; you can lightly press the brake if necessary, but avoid stopping completely). The principle is "slow speed, quick steering." You can stop and wait in the sections between test areas, but once you enter a test area, you cannot stop midway during the operation. Listen carefully to the voice prompts and wait for the computer to confirm your operation (about 3 seconds) before proceeding to the next action—do not rush. Ensure you steer correctly: "Look at the front when moving forward, look at the rear when reversing, and steer toward the intended direction." Avoid turning the wheels while stationary (though it won’t incur penalties)—it’s better to stop with the wheels and steering aligned. 2. Main test items: Reversing into a garage—the candidate must find the right reference points, reverse in from one side, drive out to the other side, and then reverse in again from that side. Parallel parking—the candidate must park the vehicle sideways into the space and engage/disengage the handbrake. Driving through curves—the easiest part; follow the instructor’s guidance, using the front of the car to trace along the curb. Turning at a right angle—identify the reference point and steer sharply to pass. Stopping at a designated spot on an uphill slope and starting on a slope—pay close attention to the stopping position; incorrect positioning will result in penalties. When starting, find the clutch’s friction point to avoid stalling, and remember to engage and release the handbrake.

Can Non-Freeze-Resistant Windshield Washer Fluid Damage the Car?

Non-freeze-resistant windshield washer fluid can damage the car, as it may cause harm to the vehicle. Non-freeze-resistant windshield washer fluid: Generally, non-freeze-resistant windshield washer fluid has a freezing point around 0 degrees Celsius. If the local temperature is low, the washer fluid may freeze, leading to issues such as the fluid itself freezing, severe cases where the washer fluid reservoir cracks, and damage to the windshield washer pump motor. Choosing windshield washer fluid: When selecting windshield washer fluid, freeze resistance should be the primary criterion. Choose a washer fluid with a freezing point at least 10 degrees below the local minimum temperature. Generally, branded washer fluids are categorized by temperature into different levels, allowing selection based on seasonal changes. Typically, 0-degree washer fluid can be used in summer, while in winter, washer fluids with at least -20 degrees or -35 degrees should be used.

Can speed be increased by changing from 60v to 72v?

Changing from 60v to 72v cannot increase speed. Timely replacement of the transmission: During the operation of the transmission, the engine mount protects the transmission from bumps. It is a rubber product that prevents the vibrations generated during the transmission's operation from being transmitted to the vehicle body. After prolonged use, the transmission mount will age, and once it hardens, its ability to filter vibrations will decrease. Therefore, it is essential to replace it promptly when signs of aging appear. Consequences of not replacing the transmission: After aging occurs, it will not immediately affect driving safety in the short term. However, prolonged failure to replace it can lead to component failures, which will impact driving safety.
