WARNING

The automatic headlights are only intended to assist the driver.

The driver must always ensure that the headlights are used when

required, and may have to switch them on manually when the light

conditions or visibility are poor. For example, the light sensors are

not able to detect fog. Therefore, you should always switch on the

headlights  in these conditions and when driving after dark.

Note

• The light sensor for automatic headlight control is located in the

mounting for the interior mirror. Do not affix any stickers on this

section of the windscreen to avoid malfunctioning of the sensor.

• The default sensitivity of the light sensor, which is set at the

factory, can be changed in the MMI menu Auto headlights

⇒ page 56.

• If the lights are left on after the key has been taken out of the

ignition lock, a buzzer sounds when the driver's door is opened.

• The use of the lighting described here is subject to the relevant

statutory requirements.

• The coming home/leaving home function is active only when the

light switch is set to AUTO.
