Interior mood lighting
The dimmed passenger compartment lighting improves visibility in the vehicle when
the light is poor.
Switching on
At night, the audio system and digital air
conditioning illumination, together with
the illumination of the central dashboard
storage box, comes on automatically when
the sidelamps are on.
On certain versions, three LEDs, located in
the rail linking the rear view mirror to the roof
come on as well.
Switching off
The interior mood lighting switches off
automatically when the sidelamps are
switched off.
It can be switched off manually by adjusting
the instrument panel lighting dimmer button
to one of the lowest settings.
