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, horse-drawn 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.
