How to Turn on the Car Brake Light?

Car brake lights are controlled by the moment of pressing and releasing the brake pedal to turn them on and off. Installed at the rear of the vehicle, the brake light features a red main body color to enhance light penetration, ensuring that following vehicles can spot the car ahead under low visibility conditions, thereby preventing rear-end collisions. The principle of the brake light switch is as follows: when the brake pedal is pressed, it pushes down the switch contact point to connect the brake light circuit, illuminating the light. Releasing the brake pedal disconnects the switch contact, turning off the brake light.

How to Deal with Foggy Car Windshield on Rainy Days?

Press the defogging button, turn on the air conditioning cooling (A/C) switch, set the temperature to the lowest, and turn on the external circulation to defog. Both cold and warm air can be used to defog the car windshield, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it may initially increase fogging. When the car windshield fogs up, turn on the external circulation. The reason for car windshield fogging: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface of the side with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fogging. Methods to defog the car windshield: Air Conditioning Cooling: Use the dehumidification function of the air conditioning system to reduce air humidity and remove fog. In summer, especially when multiple people enter the car and the air conditioning is not turned on in time, the high humidity of exhaled air can quickly cause the windshield to fog up. At this time, turn on the air conditioning and blow cold air onto the windshield. Using the dehumidification function of the air conditioning system, the fog on the windshield can be removed quickly. However, if the humidity is too high and the air conditioning is not effective enough, slightly opening the windows can quickly reduce the humidity inside the car. Of course, combining this with the air conditioning can speed up the process. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, blowing warm air onto the glass can quickly raise the temperature of the windshield, reducing the temperature difference between the inside and outside surfaces of the glass, thereby preventing excessive fogging. However, it should be noted that the rear and side windows heat up more slowly, so it takes longer to completely remove the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification. The temperature control of the air conditioning should not be set to the coldest position, as this may cause fogging on the outer surface of the windshield over time. Applying Anti-Fog Spray or Other Preventive Measures: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed, which effectively prevents water vapor from condensing on the glass and forming fog. This is especially suitable for cold winters. Alternatives to anti-fog spray include dish soap, soapy water, glycerin, alcohol, or salt water. After applying and letting it dry, use a chamois or soft dry cloth to remove excess residue. This can keep the car windows fog-free for several days. Opening Windows for Air Circulation: If the fog inside the car is not too heavy, you can open the windows on both sides to create air circulation between the inside and outside of the car, reducing the temperature difference and gradually eliminating the fog. The principle of this method is the same as using cold air from the air conditioning. However, the downside of opening windows for air circulation is obvious—it cannot be used during rain, snow, on highways, or when the fog is too heavy. Rear Window Heating: Most cars have a rear window heating function, although the button positions may vary, the function is the same. Turn on the rear window heating switch, and the fog on the rear window will disappear in about a minute.

What causes the clicking sound when the car fails to start?

The reason for hearing a clicking sound when the car fails to start is usually due to insufficient battery power or low voltage. Before turning off the car, forgetting to turn off the headlights or some electrical equipment can drain the battery, leading to insufficient power. Additionally, if the battery has been used for too long and is severely aged, the voltage may be insufficient, requiring replacement. Methods for maintaining the car battery include: 1. Avoid excessive discharge of the battery; if discharged excessively, recharge it promptly; 2. If the vehicle is unused for a long time, disconnect the battery power; 3. Prevent short circuits in the battery; 4. Regularly check if the connections are secure and if the terminal surfaces are clean to ensure good contact; 5. Never place metal tools or conductive objects near the battery terminals to avoid short circuits.

What are the symptoms of a faulty oil cooler?

The symptoms of a faulty oil cooler are: 1. Oil leakage; 2. Presence of oil floating in the coolant reservoir; 3. Reduced airflow through the cooling fins; 4. Excessive oil temperature; 5. Insufficient antifreeze in the radiator; 6. Oil degradation leading to engine wear; 7. Blocked or ruptured pipes; 8. Overlapping or deformed cooling fins; 9. Non-functioning fan; 10. Presence of oil in the radiator. The oil cooler, also known as an oil cooler, is a cooling device used in diesel engines. Its function is to absorb heat from the coolant during cold starts to warm up the oil quickly, and to dissipate heat through the coolant when the temperature is too high.

What is the curb weight of the Baojun 730?

The curb weight of the Baojun 730 is approximately 1.5 tons. Curb weight, also known as kerb weight, refers to the total weight of a vehicle when it is fully equipped according to factory specifications (including items like spare tires and tools) and with all fluids topped up. It is a crucial design parameter for automobiles. The Baojun 730 measures 4780mm in length, 1780mm in width, and 1740mm in height, with a wheelbase of 2750mm. The model is equipped with two engine options: a 1.5-liter turbocharged engine and a 1.5-liter naturally aspirated engine. The 1.5-liter turbocharged engine delivers a maximum power output of 108kW and a peak torque of 250Nm, with maximum power achieved at 5200 rpm and peak torque available between 2200 to 3400 rpm. This engine features DVVT (Dynamic Variable Valve Timing) technology, multi-point fuel injection, and utilizes an aluminum cylinder head with a cast iron cylinder block.
