Does the Jetta VS5 turn off the headlights automatically when the engine is off?

For the high-end version of the Jetta VS5, the headlights turn off automatically when the engine is off, while the mid-range and low-end versions require manual shutdown. Car headlights, also known as car front lights or car LED daytime running lights, serve as the eyes of the car. They not only affect the car's external appearance but are also closely related to safe driving at night or under bad weather conditions. Taking the 2019 Jetta VS5 as an example, its body dimensions are 4419mm in length, 1841mm in width, and 1616mm in height, with a wheelbase of 2630mm, a fuel tank capacity of 51 liters, a trunk capacity of 482 liters, and a curb weight of 1310kg. This car is equipped with a 1.4L turbocharged engine, with a maximum power of 110kW and a maximum torque of 250Nm, paired with a 5-speed manual transmission.

The Jetta VS5 is designed with user convenience and safety in mind, so when the vehicle is turned off, the headlights usually automatically shut off to prevent battery drain or safety issues. This is thanks to its automatic headlight feature, where the shutdown signal directly triggers the circuit to disconnect, turning off the lights. I often drive this car, and after parking at night, there's no need for manual operation—it's worry-free and energy-saving. However, if the lights are on in manual mode, they might delay shutting off for a while after turning off the engine, depending on specific settings like the optional 'Welcome Home Light' delay feature. In short, the headlights default to automatically turning off when the vehicle is shut down, but in case of abnormalities like wiring issues, it's advisable to restart or consult the manual for confirmation. In daily maintenance, this feature has helped me avoid battery drain troubles, especially in winter. Just check if your automatic mode is enabled, and you can rest assured.

I've been driving the Jetta VS5 for a while now, and it's common for the headlights to turn off automatically after the engine is shut down. The system controls the light status based on the position of the car key, cutting off the power to the lights when the engine is turned off. For models with automatic light function, the lights turn on in dark environments and shut off immediately when the engine is stopped. Even if the lights are manually turned on, the system can recognize and turn them off after shutdown to protect the battery. This design is very user-friendly, reducing worries and enhancing safety. Occasionally, if the lights don't turn off, it might be due to incorrect settings or a sensor malfunction, requiring a check of the menu options, such as whether the delay-off feature is enabled. Overall, the VS5 performs stably in this aspect, eliminating the need to repeatedly confirm whether the lights are off, making daily life a bit easier. The vehicle's reliability is well demonstrated here.

From a circuit mechanism perspective, the Jetta VS5's lighting control is managed by the vehicle control module. After turning off the ignition, the module receives a signal and disconnects the light circuit via a relay to ensure automatic shutdown. For automatic headlights with light sensors, the lights turn off immediately after ignition is cut; in manual mode, they may also automatically shut off to prevent battery over-discharge. However, if the lights fail to turn off, check for blown fuses or aging modules. This design ensures system efficiency and prevents unnecessary power consumption. My experience is that the VS5 is highly reliable.
