Daytime running lights cannot be turned on manually; they automatically activate when the vehicle is started to ensure driving safety and alert passing vehicles and pedestrians. Below are some details about daytime running lights: 1. Daytime running lights generally do not have an independent switch; aftermarket installations should be connected to the ACC fuse. 2. Daytime running lights should automatically turn on after the vehicle's engine starts. After dark, the driver needs to manually turn on the regular headlights, and the daytime running lights will automatically turn off. 3. Daytime running lights are only equipped on a few high-end vehicles, making them a symbol of premium cars. Therefore, these lights are not for illumination but serve as signal lights. Of course, installing daytime running lights can make a car look cooler.

On most vehicles, the daytime running lights (DRLs) turn on automatically as soon as the car starts, requiring no manual operation. This design enhances your vehicle's visibility to other drivers, particularly during overcast conditions, rain, fog, or dusk, thereby reducing accident risks. They are enabled by default as many newer models comply with regulatory requirements. To verify functionality, simply start the engine and check if the lights illuminate. If adjustable, you may find the on/off option via steering wheel buttons or the infotainment menu, though keeping them active is recommended for safety. Should the DRLs fail, potential causes include blown fuses, burnt-out bulbs, or faulty wiring—prompt professional inspection is advised. Utilizing LED technology, DRLs consume minimal power with negligible impact on fuel efficiency. Maintenance involves periodic lens cleaning to preserve brightness.

What Causes Water to Come Out of a Car's Exhaust Pipe?

The reasons for water coming out of a car's exhaust pipe are: 1. After gasoline is completely burned, it forms water and carbon dioxide. Water produces steam at high temperatures, which is colorless and transparent. When the temperature drops below 100 degrees, the steam turns back into water; 2. When the ambient temperature is low, the white smoke emitted from the exhaust pipe is steam, which condenses and accumulates into water droplets. Methods for maintaining the exhaust pipe include: 1. Preventing muffler corrosion: Avoid water entering the muffler during car washing or driving in the rain. If water accidentally enters, start the engine and let it idle for 10 minutes to expel the accumulated water; 2. Preventing muffler discoloration: Clean the muffler surface promptly if it is covered with a large amount of mud or dirt to prevent affecting its heat dissipation.

Where to Check the National Emission Standard of a Vehicle?

The location to check the national emission standard of a vehicle is: 1. Check the vehicle conformity certificate, which comes with the vehicle when it leaves the factory and clearly states the emission standard; 2. Look for the vehicle inventory list, where the emission standard can be found in the vehicle information section; 3. Examine the conformity certificate, which includes exhaust emissions and specifies the corresponding emission standard; 4. Visit the official vehicle environmental protection website, find the public query platform at the bottom of the homepage, enter the vehicle's VIN code and the last 6 digits of the engine number to check; 5. Inspect the vehicle's environmental protection label, which has a clear mark on the back indicating the vehicle's emission standard, located on the front windshield.

What are the methods for a car to judge distance?

Methods for a car to judge distance include: 1. Judging distance based on rearview mirrors; 2. Using wheel position to judge distance; 3. Judging distance based on parking sensors. The method for judging distance based on rearview mirrors is as follows: 1. When the car image occupies the entire rearview mirror, the distance is 3m; 2. When the car image occupies two-thirds of the rearview mirror, the distance is 5m; 3. When the car image occupies half of the rearview mirror, the distance is 9m; 4. When the car image occupies one-third of the rearview mirror, the distance is 12m. The method for judging distance based on parking sensors is: Determining the distance through sound. Parking sensors emit beeps at a certain frequency, and the frequency increases as the obstacle gets closer. When the beeping frequency becomes faster and is accompanied by a continuous sound, it indicates that the vehicle is getting closer to the obstacle.

What does ADS mean in cars?

ADS in cars refers to the Adjustable Damping System, which is an adjustable shock absorber. This system allows the driver to adjust the stiffness of the shock absorber according to personal preferences, road conditions, and usage requirements, catering to different needs. ADS works by varying the damping force of the shock absorber. In a stiffer mode, it provides greater damping force, enhancing shock absorption for aggressive driving. In a softer mode, it offers lower damping force, delivering a smoother ride. Common car suspension kits mainly consist of springs and shock absorbers. The springs provide vibration filtration for the vehicle body, while the shock absorbers effectively suppress the back-and-forth vibrations of the springs during rebound and absorb impacts from the ground.
