Notes
iIf you drive in countries with left-hand
driving, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized Mercedes-Benz Center.
iVehicles equipped with active Bi-Xenon
headlamps:
The active Bi-Xenon headlamps increase
usable illumination over conventional
headlamps because they follow the
curvature of the road ahead. The beams of
the active Bi-Xenon headlamps shift to
either side according to the vehicle’s
steering angle and speed.
