iIf you drive in countries where vehicles drive
on the other side of the road than the country
where the vehicle is registered, you must have
the headlamps modified for symmetrical low
beams. Relevant information can be obtained at
your authorized Mercedes-Benz Center.
iVehicles equipped with active Bi-Xenon*
headlamps:
The active Bi-Xenon headlamps monitor your
steering angle and driving speed, then
automatically shift their beams to either side to
better follow the curvature of the road ahead,
increasing usable illumination over conventional
headlamps.
iIf you hear a warning signal you have
forgotten to switch off the headlamps before
opening the driver’s door.
In addition the message
Turn off lamps
appears in the multifunction display. Vehicles
with KEYLESS-GO*, this message is only dis-
played for approximately 1 second. It is then
overwritten by the message,
