Warning!
G
If the exterior lamp switch is set toU,
the headlamps may switch off unexpect-
edly when the system senses bright am-
bient 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, acti-
vate 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.
