C. Foglamp selection ring.
The foglamp operates with the dipped and main beam headlamps.
Rear foglamp.
Turn the ring C forwards and release to switch on the rear foglamp.
When the lighting is switched off automatically (with AUTO model)
or when the dipped beam headlamps are switched off manually, the
foglamp and the sidelamps will remain on.
Turn the ring C rearwards and release to switch off all the lamps.
In good or rainy weather, both day and night, use of the rear
foglamp is prohibited. In these situations, the power of its beam
may dazzle other drivers. It should only be used in fog or snow.
In these weather conditions, it is your responsibility to switch
on the foglamp and dipped beam headlamps manually as the
sunshine sensor may detect suffi cient light.
Do not forget to switch off the rear foglamp when it is no longer
needed.
Switching off the lamps when the ignition is switched off
On switching off the ignition, all of the lamps turn off immediately,
except for dipped beam if guide-me-home lighting is activated.
Switching on the lamps after the ignition is switched off
To reactivate the lighting control, rotate ring A to the "0" position -
lamps off, then to the desired position.
On opening the driver's door a temporary audible signal warns the
driver that the lighting is on.
The lamps, with the exception of the sidelamps, switch off
automatically after a maximum duration of thirty minutes to
prevent discharging of the battery.
