Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page81.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, as otherwise it may no longer be
possible to start the engine.<
Low beams
The low beams light up in switch position2 only
with the engine running. Otherwise the parking
lamps are lit.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
If desired, the light switch can be left in
the position3. The exterior lighting is
automatically switched off after switching off
the vehicle.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog. To avoid safety risks, you
should always switch on the lamps manually
under these conditions.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.
iDrive, for explanation of principle, refer to
page16.

and off in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page80.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, reacting to oncoming traffic and traffic
ahead and to well-lit areas such as towns and
cities.
Manually switching between high and
low beams
You can intervene at any time if you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, but you want to use the low
beams, simply switch to the low beams with
the turn signal lever. This also deactivates
the high-beam assistant.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, but you want to use the high
beams, switch to the high beams in the
accustomed manner. The system is deacti-
vated in the process and you must switch to
the low beams manually.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.>You use the headlamp flasher in the usual
way when the low beams are on.
System limits
The high-beam assistant cannot replace
personal decisions about the benefits of
using high beams. In situations that require
them, you should switch to the low beams man-
ually to avoid a safety risk.<
In the following sample situations, the system
either does not function or functions only in a
limited way and a personal reaction may be
required:
>Under extremely unfavorable weather con-
ditions, such as fog or heavy precipitation
>To make out poorly-lit road users such as
pedestrians, cyclists, people on horseback,
horse-drawn vehicles, train or ship traffic
close to the road and wild animals crossing
the road
>In tight curves, on steep hilltops or in
depressions, with cross traffic or partially
concealed oncoming traffic on the freeway
>In poorly lit places and with highly reflective
signs
>In the low speed range
>When the windshield is fogged up, dirty or
covered with stickers, decals, etc. in the
area of the interior rearview mirror
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner
