Mercedes-Benz ML320. Manual — part 222

Fog and other lighting influences, e.g., due to oncoming traffic, do not have any effect on the automatic

driving light actuation.

Automatic driving light actuation when starting a journey and during it



Automatic driving light actuation with driving lights is only possible when the engine is running (circuit
61 ON).



When the engine is switched off and the electronic starter switch is in position "2" (circuit 15 ON) only
the side lamps and the license plate lamps are actuated.



Driving light actuation is disabled as soon as one of the basic prerequisites changes, e.g. when changing
from darkness to daylight after driving through a tunnel.

Automatic driving light actuation at the end of a journey or in darkness



After switching off the engine (circuit 61 OFF) and when the electronic starter switch is in position
"2" (circuit 15 ON), only the side lamps and the license plate lamps remain on.



The exterior lighting is switched off as of key position "1" (circuit 15R).
