Night security illumination
At low ambient light conditions and with the engine
having been switched off, the exterior lamps (fog lamps
and parking lamps) switch on for added illumination,
(except in daytime running mode). After the last door
has been closed the lamp-on time period commences.
See the individual setting menu “LIGHTING” –
“HEADLAMPS DELAYED SWITCH–OFF” on page 128,
for instructions on how to activate the function.
The lamp-on time period for night security illumination
can be set at several different timed levels from 0 (off) to
60 seconds, see the individual setting menu
“LIGHTING” – “HEADLAMPS DELAYED SWITCH–OFF”
on page 128. Notes:
Within 10 minutes after closing the last door the night
security illumination can be reactivated by opening a
door.
If after switching the engine off, no doors are opened or
if after opening the doors they are not closed, the night
security illumination will switch off automatically
after 60 seconds.
Deactivating night security illumination temporarily:
Turn the electronic key in starter switch to position 0
then to position 2 and back to position 0 again before
getting out of the vehicle. The night security
illumination will not be activated when the door is
opened.
