sition and the all-weather lights are switched off.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Automatic headlights are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head-
lights and to turn them on manually based
on the current light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.
