ambient light, for example light from
oncoming traffic.
the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others,
activate headlamps by turning exterior lamp
switch toB when driving or when traffic
and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toB with the
vehicle at a standstill. Switching fromU
toB will briefly switch off the head-
lamps. Doing so while driving in low ambient
lighting conditions may result in an acci-
dent.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle's lights at all
times.
