WARNING
When the light switch is set to 0058, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
The automatic headlamp feature is only an aid.
The driver is responsible for the vehicle's light-
ing at all times.
The daytime running lamps improve the visibility
of your vehicle during the day. To do this, the
daytime running lamps function must be
switched on using the on-board computer
(Y page 166).
If the drive system is switched on and you turn
the light switch to 0060or0058, the manual
settings take precedence over the daytime run- ning lamps.
Low-beam headlamps Even if the light sensor does not detect that it isdark, the parking lamps and low-beam head-
lamps come on when the ignition is switched on
and the light switch is set to the 0058position.
This is a particularly useful function in the event of rain and fog. Exterior lighting
