Here are several reasons why the air conditioning cools the car while driving but it gets hot when parked: 1. Poor heat dissipation in the air conditioning and engine cooling system: High temperatures when parked cause the air conditioning to perform poorly. When driving, the enhanced heat dissipation capacity allows the air conditioning to function normally. Common issues include a dirty radiator condenser. Over time, the condenser surface accumulates a lot of dirt, which needs to be cleaned regularly to maintain the air conditioning in good condition. Another issue is a malfunctioning cooling fan. If the fan does not turn on when the air conditioning is started at idle, the fan may be broken and needs to be replaced with a new electronic fan. 2. Poor performance of the air conditioning system: For example, Freon leakage or insufficient Freon added during replacement can prevent the air conditioning from achieving good cooling effects during operation.

Where is the windshield washer fluid reservoir located in the X-Trail?

X-Trail's windshield washer fluid needs to be refilled in the engine compartment. To refill, first open the engine hood, then locate the cap marked with a water spray symbol on the left side - this is the windshield washer fluid reservoir. Simply pour the washer fluid directly into this opening. When adding fluid, be careful not to overfill. Some foam at the reservoir opening is normal and won't affect usage. The X-Trail windshield washer fluid refill procedure is as follows: 1. First use the wiper switch knob to spray out the old washer fluid. 2. After completely draining the old fluid, add a small amount of new washer fluid solution. 3. Activate the wiper switch again to clean out any remaining old solution. 4. When no more fluid sprays from the nozzles during this second activation, fill the reservoir with approximately 4L of new washer fluid to complete the process.

Compression Ratio 9.5:1 - What Grade of Gasoline to Use?

If the engine's compression ratio is 9.5:1, it is recommended to use 95-octane gasoline. Engines with a compression ratio above 9 should generally use 95-octane fuel, as higher compression ratios typically require higher-octane gasoline. Below is relevant information about the relationship between compression ratio and gasoline grades: The correlation between compression ratio and gasoline grades: The primary basis for selecting gasoline grades is the engine's compression ratio, because the air-fuel mixture generates heat during compression - the greater the cylinder pressure, the higher the temperature becomes. For example, engines with compression ratios below 8 can use 90-octane gasoline. Gasoline's anti-knock properties: After the air-fuel mixture enters the cylinder, the piston moves upward to compress the mixture. As pressure increases, temperature rises sharply. If the gasoline's anti-knock properties are insufficient, combustion may begin spontaneously before spark plug ignition, causing engine knocking. A vehicle's compression ratio represents the ratio between the cylinder's maximum volume at bottom dead center and minimum volume at top dead center during the compression stroke. Gasoline octane rating indicates the fuel's actual anti-knock performance relative to standard gasoline. Higher octane numbers indicate stronger anti-knock capabilities.

Has the Scrapping Period for China IV Motorcycles Been Cancelled?

China IV motorcycles have not had their scrapping period cancelled for now. The quality of motorcycles is getting better and better, and there are more and more large-displacement motorcycles. The mandatory scrapping period has always restricted the development of China's motorcycle industry. Although there is related news that the mandatory scrapping will be cancelled, that result will only come several years later. The difference between guided scrapping and mandatory scrapping: Guided scrapping is a recommendation for scrapping, but if the vehicle still meets the requirements for continued use, it does not have to be scrapped. Mandatory scrapping means it must, absolutely, and definitely be scrapped. There are 4 standards for mandatory scrapping: Having reached the stipulated service life; After repair and adjustment, still not meeting the national standards for motor vehicle safety technology regarding in-use vehicle requirements; After repair and adjustment or the adoption of control technology, the emissions of pollutants or noise into the atmosphere still not meeting the national standards regarding in-use vehicle requirements; Failing to obtain the motor vehicle inspection qualification mark for three consecutive motor vehicle inspection cycles after the expiration of the inspection validity period.

How to adjust the headlight height of Audi A4L?

Audi A4L headlight height adjustment: The height can be self-adjusted using tools via the knob at the rear of the headlight assembly. The specific manual adjustment method for Audi A4L high beam height is as follows: 1. Find a wall, ensure the ground is level, and park the car approximately 10 meters away from the wall. 2. Measure the height from the ground to the center of the headlight and the distance between the two headlights. 3. Place a horizontal masking tape on the wall 0.1 meters lower than the headlight height, ensuring the tape is centered directly in front of the car. 4. Turn on the headlights. 5. Adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall. 6. Continue adjusting the vertical screw until the beam projects straight forward. To ensure accuracy, measure the height of the beam on the wall and the headlight height, confirming they are equal. Generally, there are no strict regulations for headlight height adjustment: The standard is to illuminate the road without interfering with the vision of drivers in front. During self-adjustment, use multiple reference points for comparison and repeatedly adjust until satisfactory.

How to fix the issue of the 2011 Tiguan sunroof not closing when tilted up?

Tiguan sunroof not closing when tilted up may be caused by foreign objects in the sunroof guide rails or a malfunction of the sunroof motor. If there are obstructions in the sliding rails or insufficient lubrication, excessive resistance can prevent it from closing. First, inspect the sliding rails: When there is insufficient lubrication and excessive resistance, the sunroof will activate the automatic anti-pinch feature, resulting in failure to close. The main maintenance for the sunroof involves lubricating the sliding rails. Lack of lubrication over time can lead to abnormal noises, poor movement, incomplete sealing, or even jamming and misalignment, which may burn out the motor. Check the electrical circuit: Inspect whether the fuse for the electric sunroof has blown. If the fuse is intact, check if the sunroof switch is damaged. Press the switch to see if power is being supplied. If there is power, then check if the sunroof drive motor is functioning by listening for the sound of the motor operating. Additionally, the sunroof not sealing properly could be due to obstructions, deformation, rust, or poor lubrication in the sliding channels.

Do I need to signal when starting from a fixed point in Subject 2?

In Subject 2, you need to signal when starting from a fixed point. The reason for signaling when starting from a fixed point is that parking is usually done on the right side, and starting onto the main road requires moving to the left, so you should use the left turn signal. Below is a detailed introduction to Subject 2: Test Content: Reverse from starting point A into garage B and stop correctly, move forward to the turnaround area C and stop, reverse from the turnaround area into garage B and stop, then return from garage B to A to complete the test. Evaluation Criteria: Failing to follow the designated route or sequence results in disqualification. Disqualification also occurs if the vehicle body crosses the line, fails to reverse into the garage, stops midway, or takes more than 210 seconds to complete the reversing into the garage. Test Items: Part of the motor vehicle driver's license assessment, it is the abbreviation for the field driving skill test. For small cars C1 and C2, the test items include reversing into a garage, parallel parking, starting on a slope, turning at a right angle, and driving on a curve.
