The dipped beam headlights will only work with the ignition on.
The symbol
 next to the light switch will light up when the side
lights or headlights are on.Automatic headlight control (AUTO)*
When the switch is set to AUTO, the headlights switch on automati-
cally according to the ambient light conditions, for instance in a
tunnel, at sunset, or in the rain or snow. The
 symbol lights up
when the dipped headlights are on. The headlights are switched on,
regardless of the light conditions, when you switch on the fog
lights.
The headlights are switched off automatically when you switch off
the ignition.
On vehicles with a rain sensor, the headlights switch on automati-
cally after several windscreen wiper cycles. The instrument lighting
does not switch on, however.
While using the automatic headlights you can activate the main
beam headlights as normal if this function has been activated in the
MMI. However, if you switch on the main beam headlights while
using the AUTO function and then do not switch back to the dipped
headlights setting, only the dipped headlights will come on the next
time you switch on the AUTO function. To be able to use the main
beam headlights again you must first pull the main beam lever back
to the "off" position and then push it forward to "on".
Malfunction of light sensor
If a malfunction should occur in the light sensor, the instrument
cluster will show the message:
 Automatic headlights / automatic wipers defective
For safety reasons, the dipped beam headlights will then be
switched on permanently when the light switch is set to the AUTO
position. However, you can still switch the lights on and off in the
normal way with the light switch. You should have the light sensor
checked by a qualified workshop as soon as possible.
