Automatic headlight control
In the switch pos ition AUTO the automatic headlight control is
t u rned on. The low beams are t urned on automatically t hrough a light
sensor as soon as ambient br ight ness (e .g . when dr iving into a
t u nnel) falls below a val ue p reset at the factory . When ambient .,.
brightness increases again, the low beams are turned off again auto
matically =>& .
In the
AUTO position the low beams are switched off automatically
when the ignition is turned off.
Light Sensor Malfunction
In the event of a light sensor ma lfunct ion, the driver is notified in the
instrument cluster display:
Automatic headlights/automatic wipers defective
For safety reasons the low beams are turned on permanently with t he
switch in
AUTO. However, you can continue to turn the lights on and
off using the light switch. Have the light sensor checked as soon as
possible at a dealership.
& WARNING
• Never use daytime running lights to see where you are going.
They are not bright enough and will not let you see far enough
ahead for safety, especially at dusk or when it is dark. Always
switch on the low beams at dusk or when it is dark.
• Automatic headlights are only intended to assist the driver .
They do not relieve the driver of his responsibility to check the
headlights and to turn them on manually according to the current
light and visibility conditions. For example, fog and rain cannot be
detected by the light sensors. So always switch on the headlights
under these weather conditions and when driving in the dark
io.
• Crashes can happen when you cannot see the road ahead and
when you cannot be seen by other motorists.
- Always turn on the headlights so that you can see ahead and
so that others can see your car from the back.
[ i ) Tips
• With the switch in AUTO front fog lights and rea r fog ligh ts cannot
be turned on in addition .
