If the reversing radar does not beep or provide any relevant prompts when the vehicle is approaching an obstacle behind, it indicates that the system may have malfunctioned and requires inspection. The troubleshooting steps for a non-functioning reversing radar are as follows: 1. Check whether the wiring of the reversing radar at the rear bumper is properly connected. 2. Observe whether the reversing light turns on when the reverse gear is engaged; if not, inspect the reversing light switch. 3. Remove the right-side lining of the trunk and test the continuity of the wires connected to the radar. 4. Open the fuse box and use a multimeter to check the continuity of the fuses related to the reversing radar. 5. If the reversing radar module or buzzer is damaged, it needs to be replaced.

Where is the Air Conditioning Filter in a New Energy Vehicle?

The air conditioning filter in a new energy vehicle is located in front of the passenger seat, beneath the glove compartment. Functions of the Air Conditioning Filter: It ensures the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and abrasive particles from the air. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, providing strong and long-lasting moisture adsorption. It prevents the car windows from fogging up, ensuring clear visibility for the driver and passengers and safe driving. It supplies fresh air to the cabin, preventing occupants from inhaling harmful gases and ensuring driving safety. It also effectively sterilizes and deodorizes. Cleaning the Air Conditioning Filter: The filter easily accumulates dust, which can be removed using compressed air or similar methods. Never wash it with water, as this can easily damage it. Over time, the activated carbon filtration function of the air conditioning filter diminishes, so it is recommended to replace the filter at a 4S shop.

How Long Does It Take for the Hood to Cool Down?

After the engine is turned off, the hood needs to cool down for approximately 30 to 60 minutes. The hood serves the function of air diversion: For objects moving at high speeds in the air, the air resistance and turbulence generated by the airflow around the moving object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and reduce the obstructive force it generates, minimizing the impact of airflow on the vehicle. The hood protects the engine and related components: Under the hood lie critical components of the car, including the engine, electrical circuits, fuel system, braking system, and transmission system, all of which are vital to the vehicle. By enhancing the strength and structure of the hood, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle.

What is the original factory oil for Hyundai ix35?

Modern ix35's original factory oil model is 5w20. The following are the relevant instructions: 1. The letter w in the oil model is an abbreviation for winter, representing winter. If there is a letter w in the oil model, it means that this oil can be used normally in winter. 2. The number before w indicates the low-temperature fluidity of the oil. 0w means the oil can flow normally at minus 35 degrees Celsius; 5w means the oil can flow normally at minus 30 degrees Celsius. 3. The number after w indicates the high-temperature viscosity of the oil. The larger the number, the greater the viscosity. 4. When choosing oil viscosity, be sure to select it according to the technical characteristics of your car's engine. 5. Generally, a naturally aspirated engine can use oil with a viscosity of 20 or 30; generally, a turbocharged engine needs to use oil with a viscosity of 30 or 40.

How to Use the Four-Wheel Drive on the Prado?

Here is how to use the four-wheel drive on the Prado: 1. Select the H4F full-time four-wheel drive mode button on the center console, and the engine power will be distributed 40% to the front and 60% to the rear. 2. When encountering complex road conditions, choose the H4L high-speed four-wheel drive lock mode, which ensures equal power distribution to both front and rear wheels. Below is additional information on the differences between four-wheel drive and two-wheel drive vehicles: 1. Power performance: Four-wheel drive offers better power performance than two-wheel drive. 2. Handling: Front-wheel drive in two-wheel drive vehicles tends to understeer, while rear-wheel drive tends to oversteer; four-wheel drive provides better handling. 3. Off-road capability: Four-wheel drive has better off-road capability than two-wheel drive. 4. Cost: The transmission structure of four-wheel drive is more complex, resulting in higher manufacturing costs, and the transmission components require maintenance, whereas two-wheel drive vehicles have lower maintenance costs.
