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.
