Electric Load Shutdown
By way of terminal R OFF, the interior lighting system is switched off by the FRM after 16
min. For this purpose, the Footwell Module sends the electric load shut-down informa-
tion via the K-CAN.
The Roof Functions Center (FZD) receives this information and switches off the interior
lighting in the roof area.
The interior lights that are switched on directly by the FRM are also switched off.
Terminal 58g
The FRM makes available terminal 58g via the K-CAN. Terminal 58g is pulse width-
modulated and features the following two brightness levels:
• The brightness level for the locator lighting can be set individually via the rocker
switch on the column stalk.
• The brightness level for the function lighting is not dimmed and is switched on
at full brightness.
