You can use this function to set the
headlamps to change betweenlow beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detectsany other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.

wrong fuel. Otherwise, the fuel will enter
the fuel system. Even small amounts of the
wrong fuel could result in damage to the
fuel system and the engine. The repair
costs are high. Notifyaqualified specialist
workshopand have thefuel tankand fuel
lines drainedcompletely.
!Overfilling the fuel tank could damage the
fuel system.
!Take carenot to spill any fuel on painted
surfaces.You could otherwise damage the
