Why do daytime running lights stay on after locking the car?
2 Answers
Daytime running lights remain illuminated after turning off the engine due to delayed shut-off. Here are some key points about daytime running lights: 1. Driving safety: In low-light conditions such as cloudy or hazy weather, daytime running lights function like signal lights, making your vehicle more visible to pedestrians and other drivers, thereby reducing accident risks. 2. Reducing accident rates: Many modern vehicles are equipped with daytime running lights. Statistics show that these lights can reduce accident rates by 15%. There's no need to worry about daytime running lights consuming significant amounts of electricity or fuel.
I once encountered an issue with my car's daytime running lights staying on after locking the car, which gave me quite a scare thinking they were broken. The reason was that the "Follow Me Home" function in the vehicle settings was activated, designed to light your way after unlocking in the dark. Typically, these lights automatically turn off after 20-30 seconds post-locking. If they remain on abnormally long, say for several minutes without turning off, it might indicate a malfunctioning control module or a short circuit in the wiring. I would first check the owner's manual to locate the function switch, as most cars allow you to disable it in the lighting settings on the central control screen. If this issue arose after modifying the lights, incorrect wiring might be the culprit, requiring a reset. Remember to conduct regular checks to avoid battery drain leading to starting difficulties. If necessary, have it professionally fixed at a modest cost rather than delaying and risking battery damage.
