System limits

The high-beam assistant cannot serve as 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.
