Electrically adjustable andheated outside mirrors are standard equipment.Photochromatic Interior and exterior mirrors with automatic dimming function can beordered as an optional extra. This option requires the interior rear-view mirror with auto-matic dimming function.The memory function for the outside mirrors is also available as part of electrical seatadjustment with memory.The outside mirrors are connected via the LIN-bus and additionally feature the followingfunctions:• Outside mirror fold-in.• Photochromatic outside mirrors.• Electrical seat adjustment with memory (including outside mirror memory).Introduction 5E70 Outside MirrorsThe instrumentcluster (1) registers the outside temperature and makes it available to thejunction box control unit (4), outside mirror Low (basis version). The junction box control unit powers the outside mirror heating system. The outside mir-rors (5 + 6) can be adjusted with the mirror adjustment switch in the driver's door switchcluster (6).Note:In the High version of the outside mirrors, the footwell module (2)receives the outside temperature from the instrument cluster.

Thefootwell module (15) evaluates the K-CAN signal and initiates activation of the outsidemirror heating (3 and 13).The mirror adjustment motors (7 and 9) are driven by the electronic mirror module. Theelectronic mirror module receives the request to adjust the outside mirrors via the LIN-bus.The outside mirrors are connected via the LIN-bus. All information such as the memoryposition or mirror functions, e.g. dip outside mirrors, is transferred via the LIN-bus.Note: The footwell module is the central control unit for the outside mirrorfunctions. The outside mirrors with memory function, photochromaticfunction and the fold-in function are connected with the LIN-bus.

The adjustment motors in the Low version of the outside mirrors are controlled directly by the mirror adjustment switch in the driver's door switch cluster. The driver's door switch cluster in the High version of the outside mirrors is connected to the outside mirrors via the LIN-bus. The electronic mirror module in the outside mirrors evaluates the LIN-bus signals and activates the... low version of the outside mirror heating sys- tem. The signal is pulse width-modulated and has a frequency of 1 Hz. Roof Functions Center The roof functions center serves the purpose of linking the interior rear-view mirror for the "aut omatic dipping/anti-dazzle" function of the outside mirrors. 7 E70 Outside Mirrors Legend for System Circuit Diagram - Standard Outside Mirrors The instrument...
