To turn off the automatic headlamp
system, turn the exterior lamps
switch to the off position and then
release it.
The vehicle has a light sensor on
the top of the instrument panel in
the defroster grille which regulates
when the automatic headlamps turn
on. Do not cover the sensor,
otherwise the headlamps will come
on whenever the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage, heavy overcast
weather, or a tunnel. This is normal.
If the vehicle is started in a dark
garage, the automatic headlamp
system will come on immediately.
Once the vehicle leaves the garage,
it takes approximately one minute
for the automatic headlamp system
to change if it is bright enough
outside. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6 6.
To idle the vehicle with the
automatic headlamp system off, turn
the control to the off position.
The headlamps will also stay on
after you exit the vehicle. This
feature can be programmed using
the Driver Information Centre (DIC).
See Vehicle Personalisation on
page 5 47.
The regular headlamp system can
be turned on when needed.
Lighting
Lights On with Wipers
If the windscreen wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for
the lamps coming on varies based
on wiper speed. When the wipers
are not operating, these lamps turn
off. Move the exterior lamp control
to or to disable this feature.
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlights
horizontally to provide greater road
illumination while turning. To enable
AFL, set the exterior lamp switch on
the multifunction lever to the AUTO
position. Moving the switch out of
the AUTO position will deactivate
the system. AFL will operate when
