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, 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.
