For Passat B8 For Arteon 2015 2016 2017 2018 2019 Engine Key Start Stop Push Button Switch Mountain road driving adaptation: Meets the driving needs of mountain slopes, curves, and undulating road conditions, flexibly adjusting vehicle conditions through start-stop operations, adapting to the power control rhythm in complex road conditions. Anti-interference in Strong Vibration Environments: Internal components employ a reinforced and locking structure to withstand continuous vibrations during driving, preventing functional abnormalities and false command triggering caused by vibrations. This feature automatically shuts off the engine when the vehicle comes to a temporary stop—such as at a red light or in a traffic jam—and quickly restarts it when the brake is released or the accelerator is pressed. Its purpose is to save fuel and reduce exhaust emissions. The primary function of the engine start-stop switch is to enable or disable the automatic start-stop system.
