How Often Should a Car Air Conditioner Be Maintained?

Why does the air conditioning cool when stepping on the accelerator but not when not stepping on it?

The reasons why the air conditioning cools when stepping on the accelerator but not when not stepping on it: 1. Poor heat dissipation of the condenser: You can clean the condenser with water when washing the car or take it to a quick repair shop to blow the condenser with an air pressure gun, and also check the refrigerant pressure. 2. Excessive refrigerant: When the accelerator is pressed, the compressor speed increases, and the high pressure rises. Due to excessive refrigerant, the high pressure becomes too high, causing the high pressure protection switch to trip and stop cooling. Conversely, when driving at low speeds, the high pressure is normal and not too high to trigger the high pressure protection, allowing the compressor to cool normally. 3. Excessive dirt in the refrigeration oil: This can clog the filter screen of the filter, reducing the cooling effect, increasing resistance, and decreasing the flow of refrigerant to the expansion valve, leading to the car air conditioning not cooling. Sometimes, if air enters the car air conditioning system, it can cause excessive pressure in the refrigerant pipes, and poor refrigerant circulation can also lead to insufficient cooling.

Can 75% Alcohol Be Carried in Private Cars?

From a safety perspective, it is not recommended to store 75% alcohol in your car. Here are the relevant details: It can easily cause spontaneous combustion and explosions: In summer, alcohol left in the car can spontaneously combust. The common 75% medical alcohol has a flashpoint of 20 degrees Celsius, while the highest outdoor temperature at noon in summer can exceed 40 degrees Celsius. If the car is parked outdoors under the sun for a period, the interior temperature can reach over 50 degrees Celsius, making it highly likely to trigger spontaneous combustion and explosions of the alcohol. Ensure proper ventilation: Since the flashpoint of alcohol is only 20 degrees Celsius, high temperatures inside the car may cause combustion. Therefore, it is best to avoid storing alcohol in the car. If disinfection is necessary, find an open area to wipe the car interior with alcohol and ensure adequate ventilation for some time afterward. Avoid using alcohol on leather seats: When using alcohol inside the car, if the seats or steering wheel are made of leather, directly spraying alcohol on the leather can cause damage. Alcohol is an organic solvent, and especially in cars with lower-quality leather, it may change the originally smooth color to a texture resembling that of a jaguar.

Is the Volvo XC60 a domestically produced or imported car?

Volvo XC60 has both imported and domestically produced models. As of September 5, 2019, only domestically produced models are available, as the imported models have been discontinued. The Volvo XC60 is positioned as a midsize SUV, with body dimensions of 4688mm in length, 1902mm in width, and 1658mm in height, and a wheelbase of 2865mm. In terms of power, the Volvo XC60 comes in two variants: 1. Equipped with a 2.0T inline 4-cylinder turbocharged low-power version, paired with an 8-speed automatic transmission, delivering a maximum power of 140KW and a maximum torque of 300NM; 2. Equipped with a 2.0T inline 4-cylinder turbocharged high-power version, paired with an 8-speed automatic transmission, delivering a maximum power of 187KW and a maximum torque of 350NM.

How to Use Cruise Control in the Eado?

The cruise control buttons of the Eado are located near the steering wheel, with the following main functions: "SET" (set speed), "— or COAST" (decrease set speed), "RES" (resume set speed), "+ or ACCEL" (increase speed), "CANCEL" (cancel set speed), and "ON/OFF or CRUISE" (cruise control master switch). 1. To activate cruise control: Press the control switch to standby, accelerate to the desired speed, then push the control lever downward to set the cruising speed. To accelerate, push the lever upward or press the accelerator pedal. To cancel cruise control, lift the lever upward, turn off the master switch, press the accelerator, or lightly tap the brake. After pressing the cruise control master switch, the dashboard will display a cruise control icon indicating standby mode. 2. The Eado's cruise control works at any speed but can only adjust speed using the control lever above 50 km/h. Lightly tapping the brake cancels cruise control. Cruise control is suitable for use on closed roads with good conditions and low traffic. With the "CANCEL" and "RES" buttons, you can drive using a set of cruise control buttons at high speeds, except in emergencies requiring brake or accelerator pedal use.

How to reset the tire pressure light on the Soueast DX3?

Press the black stick on the instrument display until the tire pressure interface appears, which shows four yellow exclamation marks, then hold it for more than three seconds to reset. Below are the functions of the tire pressure monitoring alarm: 1. Prevent tire blowouts by monitoring tire pressure and temperature in real time, addressing issues before they occur. 2. Save fuel by maintaining proper tire pressure, reducing vehicle fuel consumption. 3. Reduce wear; insufficient pressure can cause excessive wear (tire scrubbing), shortening tire lifespan. Working principle: Each tire is equipped with a highly sensitive sensor transmitter that monitors tire pressure and temperature in real time, wirelessly transmitting data signals to the terminal receiver system inside the vehicle. When abnormalities such as air leakage, excessively high or low tire pressure, or excessively high temperature occur, the terminal will automatically alert and display the tire status, ensuring driving safety. Additionally, regularly check tire wear. Sometimes, individual vehicles may experience tire scrubbing, so it's important to frequently inspect tires, especially the inner side, for any abnormal wear, primarily observing whether the tread depth on both sides of the tire is consistent.

How to Ensure Not Crossing the Line in the S-Curve During Subject Two?

Here are the methods to ensure not crossing the line in the S-curve during Subject Two: 1. When entering the curve, position the front of the car in the middle; when the left corner of the car touches the right line, turn the steering wheel left by one full turn plus 45 degrees and maintain the course; when the left corner touches the left line of the second curve, straighten the steering wheel; when the right corner of the car touches the left line of the second curve, turn the steering wheel right by one full turn plus 45 degrees; when the car is straight again, straighten the steering wheel and slowly exit the S-curve. 2. While navigating the S-curve, it's crucial to control the speed properly. Press the clutch gently to slow down, increasing reaction time. Even if there's a slight deviation in direction, it can be adjusted in time to avoid crossing the line. 3. There are two types of entrances, left and right. For a left entrance, keep the car as close to the right line as possible before turning the steering wheel left; for a right entrance, do the opposite—keep the car close to the left line before turning the steering wheel right. This accounts for the inner wheel difference, preventing the rear wheels from crossing the line during the turn.
