Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Reduced Alarm Function
The switch for reduced alarm function is located in the climate control comfort panel. The switch is used to temporarily deactivate the level sensor, mass movement sensor module (MMS) or ultrasonic sensor module (IMS) and deadlock mode when the vehicle is locked. An integrated LED in the switch indicates when the function is activated.
The function is activated during a locking cycle, i. e. from the time the button is depressed and the vehicle is locked until the vehicle is unlocked. When the ignition is once again turned to position II, reduced function is deactivated.
Examples of applications for this function include when a person or pet remains inside the vehicle after the vehicle has been locked, and if the vehicle is transported by tow truck or onboard a ferry.
