Approach Lighting/Guide Lighting

Approach lighting is activated using the remote key for the vehicle. The function can only be activated when the ignition is off. When the yellow button on the remote key is pressed, the central electronic module (CEM) (4/56) receives an activation signal that is sent onward on the CAN network. The driver door module (DDM) (3/126) and passenger door module (PDM) (3/127) receive the signal and switch on the lighting for the left door mirror (6/62) and the lighting for the right door mirror (6/63). The function is deactivated by pressing the button on the remote key again. A signal is then sent from the central electronic module (CEM) to the driver door module (DDM) and passenger door module (PDM) requesting that the function is switched off. The function is also switched off when the ignition is switched on.

The guide lighting is activated using the left control stalk (the remote key must be removed from the start unit). The steering wheel module (SWM) (3/130) transmits a signal to the central electronic module (CEM) via LIN communication. When the car is then locked, the central electronic module (CEM) sends a signal onward via the CAN network to the driver door module (DDM) and passenger door module (PDM), which turn on the lights in the door mirrors. The lights are part of the guide lighting function and remain on for a set time (30, 60 or 90 seconds).
