Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination
of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch into position 3, refer to page102.
To avoid blinding oncoming traffic, the Adaptive
Head Light is not active when driving in reverse
and points toward the passenger side when the
vehicle is stopped.
High beams/
roadside parking lamps
1High beams

3Roadside parking lamps
Roadside parking lamps, left or right*
You also enjoy the option of lighting up just one
side of your vehicle when parking:
Switching on
After parking the vehicle, press the lever up or
down beyond the resistance point, arrow 3.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time, otherwise it may no longer
be possible to start the engine.<
Switching off
Briefly press the lever in the opposite direction
up to the resistance point, arrow3.
High-beam assistant*
The concept
This system automatically switches the high
beams on and off. A sensor on the front side of
the inside rearview mirror controls the process.
The assistant makes sure that the high beams
are switched on whenever traffic conditions
permit. This relieves you of the burden of con-
stantly switching back and forth and simulta-
neously provides you with the best possible vis-
ibility. Naturally, you can intervene at any time to
switch the high beams on and off as usual.
Activating system
1.Turn the light switch to position3, refer to
page102.
2.With the low beams switched on, briefly
press the turn signal lever in the high-beam
direction.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The system
automatically switches between high beams
and low beams, reacting to oncoming traffic,
vehicles ahead of you, and sufficiently lit areas,
e.g. in built-up zones.

Manually switching between high
beams and low beams
If you wish or the situation requires, you can
intervene at any time.
>If the high-beam assistant has switched on
the high beams, but you wish to use the low
beams, just switch on the low beams with
the turn signal lever. This deactivates the
high-beam assistant.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>If the high-beam assistant has switched on
the low beams, but you wish to use the high
beams, simply switch on the high beams as
usual. This deactivates the system and it is
up to you to switch back to low beams.
In order to reactivate the system, briefly
press the turn signal lever in the high-beam
direction.
>When the low beams are on, use the head-
lamp flasher as usual.
System limits
The high-beam assistant is designed to
maximize the amount of time that high
beams can be safely used and to quickly switch
back to low beams when traffic approaches.
The system cannot completely replace driver
intervention when unusual conditions are
encountered. For this reason, switch to low
beams when circumstances so dictate. Failure
to do so can pose a safety risk.<
Below are a few examples of situations in which
the system may not react or may only function
to a limited degree, requiring personal interven-
tion:
>in extremely unfavorable weather condi-
tions such as fog or heavy precipitation
>in sensing road users with poor inherent
illumination such as pedestrians, cyclists,
equestrians, horsedrawn vehicles, railroad
or shipping traffic close to the road, and at
deer crossings>in tight curves, on steep crests or dips, with
cross-traffic, or with partially hidden
oncoming traffic on divided highways
>in poorly illuminated areas and in the pres-
ence of 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 inside rearview mirror
>when the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth slightly moistened with glass
cleaner
Moreover, no system can operate without limi-
tations. High-beam assistant operation is sub-
ject to conditions that may reduce the system's
ability to recognize the difference between
actual vehicle head lamps or tail lamps and, for
example, highly reflective signs, markers, and
streetlights. To be on the safe side, the system
may periodically interpret these situations as
conditions that require low beams. Below are
some of the situations in which premature
switching to low beams can occur:
>approaching large and/or highly reflective
signs
>approaching certain lights, such as drive-
way lighting and porch lights
>approaching certain traffic signals
>approaching large reflective markers
In these situations, the system may interpret
the above conditions as a vehicle ahead requir-
ing a switch to low beams. When the conditions
return to normal, the system will reactivate the
high beams.
The high-beam assistant cannot replace the
driver's responsibility for complying with state
laws on high-beam switching or for adapting to
visibility and traffic conditions.
