Personal responsibility
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 freeways..
▷ In poorly-lit towns and cities and in the presence of highly reflective signs.

▷ At low speeds..
▷ When the windshield in front of the interior rearview mirror is fogged over, dirty or covered with stickers, etc..
▷ If the sensor view field is dirty.

The view field of the sensor is located on the front of the interior rearview mirror.

Do not cover this area with stickers, etc.

Clean the sensor view field with a cloth moistened with a small amount of glass cleaner.
