High-beam Assistant

The concept

This system automatically switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handles this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.

Activating the system

1.

Turn the light switch to position

3, refer to

.

2.

With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.

The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-

cally switches from high beams to low beams
and vice versa in response to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.

Switching the high beams on and off

manually

Whenever you wish, or when the situation
requires, you can intervene:

>

If the High-beam Assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deactivates the High-beam
Assistant.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.

>

If the High-beam Assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deactivates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the system, briefly push the
turn signal/high beam lever toward the high
beams again.

>

Use the headlamp flasher as usual with the
low beams switched on.

System limitations

The High-beam Assistant cannot serve
as a substitute for the driver's personal

judgment of when to use the high beams.
Therefore, manually switch off the high beams
in situations where this is required to avoid a
safety risk.

<

The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:

>

In very unfavorable weather conditions,
such as fog or heavy precipitation

>

In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings

>

In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways

>

In poorly lit towns and cities and in the pres-
ence of highly reflective signs

>

At low speeds

>

When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.

>

If the sensor is dirty. Clean the sensor on
the front of the interior rearview mirror using
a cloth moistened with a small amount of
glass cleaner.
