How to Turn on the Air Conditioning Cooling in an Audi A4?

Audi A4 air conditioning cooling activation method is as follows: 1. Turn on the car's ignition switch. 2. Turn on the air conditioning switch. 3. Press the A/C button to activate the cooling mode. Precautions for turning on the car air conditioning are as follows: 1. Select the appropriate fan speed. During normal car operation, to prevent excessive frosting of the evaporator, which could affect the air conditioning system's operation, the air conditioning's fan speed and temperature control should not be set at the lowest for extended periods. 2. Regularly start the air conditioning in winter. Prolonged disuse can cause the rubber seals to age, and the lubricating oil on internal components to dry out. Regular activation allows components to be lubricated and maintained in good condition. 3. Avoid using the air conditioning for too long in a single session. If the interior temperature has reached a comfortable level, turn off the air conditioning or switch it on again after a while. 4. Ventilate to cool down before driving in summer, then switch to recirculation mode. Upon entering the car, first open the windows for ventilation and turn on the external circulation to expel hot air. After the cabin temperature drops, switch to internal circulation.

What is the normal tire pressure and how to check it?

Normal range of tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. How to check it: The tire pressure monitoring indicator light will illuminate if the tire pressure is abnormal, and it will remain off if the pressure is normal. The tire pressure monitoring indicator is a yellow symbol, resembling an irregular circle with no top seal, four small spikes at the bottom, and an exclamation mark inside. The illumination of this light indicates abnormal tire pressure. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: The system will typically alert when the pressure is below 1.8bar or above 3.0bar. In such cases, the tires should be inspected and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure monitoring system is not reset in time, it will continue to display the previous data, causing the indicator light to illuminate. Simply reset the tire pressure monitoring system to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors the tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.

How much 92 left can be filled with 95?

You cannot fill 95 gasoline no matter how much 92 is left. If you occasionally fill up with the wrong gasoline grade, you just need to switch back to the correct gasoline grade after using it up. However, if you consistently use the wrong gasoline grade for a long time, it will have the following effects: For vehicles that recommend low-grade gasoline, filling up with high-grade gasoline will not cause damage, but the increase in octane number will change the ignition point of the fuel, leading to delayed ignition in the engine. This means both the engine's power output and thermal efficiency will decrease, and the actual feedback experience is reduced power; For vehicles that recommend high-grade gasoline, using low-grade gasoline will cause engine knocking. Because the octane number is too low, the ignition point of the gasoline decreases, causing it to ignite prematurely during the compression stroke. If the gasoline ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it's mild knocking, it only increases noise and does not cause obvious damage to the engine. However, if there is noticeable knocking, it indicates that the engine's condition is already very severe. The vibration not only affects driving stability but also causes abnormal wear on the piston and cylinder, and in severe cases, can lead to cylinder scoring. In addition to checking the appropriate gasoline grade in the car's manual, you can also check it on the fuel tank cap, which will also indicate the recommended grade. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92 gasoline, while those with a compression ratio between 10.0-11.5 should use 95 gasoline. If the compression ratio is higher, 98 gasoline should be used. However, with the use of some new technologies nowadays, the gasoline grade cannot be solely determined by the compression ratio. Engines with high compression ratios can also be tuned to use low-grade gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally speaking, the higher the gasoline grade, the higher the octane number, and the better the anti-knock performance. 92 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane.

How Long Overdue is Considered Exceeding the Deadline for 2021 Vehicle Annual Inspection?

According to the 2021 regulations, a vehicle's annual inspection is considered overdue if it exceeds the deadline by even one day. As per the "Motor Vehicle Registration Regulations," all traffic violations of the vehicle must be settled before the annual inspection. Any inspection conducted after the expiration of the annual inspection period is deemed overdue. The inspection can be conducted up to 3 months in advance or delayed by 1 month. According to the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," if the inspection is delayed by 2 months, the driver will be penalized with a 3-point deduction from their driving license and a fine of 200 yuan. According to the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," non-commercial vehicles are exempt from on-site inspections for the first 6 years, requiring only an application for an inspection mark every two years. For vehicles over 6 years but under 10 years old, inspections are required every two years, meaning private cars only need two on-site inspections within 10 years, specifically in the 6th and 8th years. Private cars aged 10-15 years require an annual inspection, while those over 15 years old require inspections every six months. Commercial passenger vehicles require annual inspections within the first 5 years and inspections every six months thereafter. Trucks and large or medium-sized non-commercial passenger vehicles require annual inspections within the first 10 years and inspections every six months thereafter. Motorcycles require inspections every two years within the first 4 years and annual inspections thereafter. According to the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," the main items of vehicle annual inspection include: Exterior Inspection: Primarily checks vehicle lights, body appearance, suspension, sunroof, and tires. It verifies whether the lights are functioning correctly, if there are any non-working lights, if the body color has been altered, and if the suspension has been modified. Emission Inspection: Checks whether the vehicle's tailpipe emissions meet national standards during high-speed operation. On-site Inspection: Focuses on the vehicle's braking system, headlights, horn, and chassis. Violation Check: Before the annual inspection, all traffic violation records of the vehicle must be cleared to pass the inspection. Vehicle annual inspections can be conducted up to 90 days in advance but must not be overdue. According to the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China," the consequences of overdue inspections are as follows: Vehicles that fail to undergo the annual inspection on time are not allowed on the road. Driving an overdue vehicle on the road results in a 3-point deduction from the driving license and a fine of 200 yuan. If an accident occurs involving a vehicle that has not undergone the annual inspection, the driver bears full or primary responsibility, and the insurance company will not cover the damages. Driving an overdue vehicle is considered illegal and may result in the vehicle being impounded.
