Exterior lamp switch
iIf you drive in countries where vehicles drive
on the other side of the road than the country in
which the vehicle is registered, you must have
the headlamps modified for symmetrical low
beams. Relevant information can be obtained at
any authorized Mercedes-Benz Light Truck
Center.
iVehicles with active Bi-Xenon* headlamps:
The active Bi-Xenon* headlamps monitor the
vehicle’s steering angle and speed, then auto-
matically shift their beams to either side to
better follow the curvature of the road ahead, in-
creasing usable illumination over conventional
headlamps.1‚Standing lamps, left
