Why Do the Mercedes-Benz Car Lights Stay On After Locking?
2 Answers
Mercedes-Benz car lights staying on after locking is due to the activation of the headlight delay shut-off feature. Below is an introduction to related Mercedes-Benz content: 1. Mercedes-Benz SAM: The control unit, also known as the Signal Acquisition and Actuation System. If the SAM malfunctions, components such as headlights, turn signals, and wipers cannot be controlled while driving, posing safety risks. 2. Mercedes-Benz: A German automotive brand, recognized as one of the most successful premium car brands globally, renowned for its impeccable technical standards, rigorous quality benchmarks, continuous innovation, and a series of classic coupe models. The Mercedes three-pointed star has become one of the most famous automotive and brand symbols worldwide. Mercedes-Benz cars not only boast unparalleled quality but also offer a comprehensive range of models, currently producing mainly A-Class (compact cars), C-Class (mid-range sedans and coupes), E-Class (high-end sedans and coupes), S-Class (luxury sedans and coupes), and G-Class (SUV off-road vehicles).
It's quite common for Mercedes-Benz car lights to remain on after locking the vehicle, mostly due to their built-in home lighting feature in action. Once this function is set up, when you lock the car, the lights will delay for tens of seconds to a few minutes before automatically turning off, primarily to provide lighting for visibility when returning home at night, preventing walking in the dark—a considerate design. If you feel it stays on too long, it might be due to an overly long setting or accidentally enabling the option. You can find the lighting settings in the vehicle's menu to shorten the delay or turn it off. Sometimes, a system bug or sensor misjudgment under certain lighting conditions may trigger it; try rebooting the car's system. Remember not to overlook this small matter to avoid unnecessary battery drain affecting its lifespan, especially if the car is left unused for extended periods. As a seasoned Mercedes driver, I recommend all owners familiarize themselves with the manual settings.
