Hazard lamps
The hazard warning lamps will continue to operate if the
ignition is switched off.
Press the hazard warning lamp button (A) to set the hazard
warning lamps to on. All direction indicator signals will flash.

the hazard warning lamps will resume operation.
Interior Lamps
Instrument Illumination
During the daylight hours the level of instrument brightness
defaults to maximum brightness. During the twilight and night
time hours, a twilight sensor located at the top of the windscreen
automatically reduces the level of brightness to a preset level.
If the twilight sensor is covered then the level of brightness
will stay low as if in night time mode. For example, when parked
in a garage.
The level of brightness can be reduced by using the illumination
dial (A).
