dashboard switches and the multifunction LCD
screen will also occur. Sidelights and dash
illumination are switched off when the sidelight
button is presses again, or the ignition is
switched off.
Dipped beam: Dipped beam can only be
activated once the sidelights have been turned
on. Press the headlight button on the dashboard
(see Interior Overview page) to switch on the
dipped beam headlights.Main beam: With the
dipped beam headlights already on, main beam is
selected by pressing either of the steering
wheel-mounted main beam buttons. The head-
lights will remain on main beam until the button(s)
are pressed again.
Flash function: Oncoming traffic can be flashed
by the main beam headlights, when not on dipped
beam. With only the DRLs/sidelights on, pressing
the steering wheel-mounted main beam buttons
will illuminate main beam for as long as the button
is depressed. The headlights will extinguish as
