The exterior lamp control is to the
left of the steering column on the
instrument panel.
There are four positions:
O : Turns the exterior lamps off and
deactivates the AUTO mode. Turn
to
O again to reactivate the
AUTO mode.
In Canada, the headlamps will
automatically reactivate when the
vehicle is shifted out of P (Park).
AUTO : Turns the headlamps on
automatically at normal brightness,
together with the parking lamps,

122 Lighting The DRL turn off when the
headlamps are turned to
O or the
ignition is off.
For vehicles first sold in Canada,
the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp
System When it is dark enough outside and
the exterior lamp control is in the
automatic position and the engine is
running, the headlamps come on
automatically. See Exterior Lamp
Controls 0 120 .
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. 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 0 124 .
Lights On with Wipers If the windshield 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
Por
; to disable this feature.
Adaptive Forward
Lighting (AFL) The AFL system adjusts the
headlamps to provide greater road
illumination in various driving
conditions.
To enable AFL, set the exterior lamp
control to the AUTO position.
Moving the control out of the AUTO position will deactivate the system.
AFL will operate when the vehicle
speed is greater than 3 km/h
(2 mph). AFL will not operate when
the transmission is in R (Reverse).
AFL is not immediately operable
after starting the vehicle; driving a
short distance is required to
calibrate the AFL. See Exterior
Lamp Controls 0 120 .
Curve Lighting
The light beam pivots based on the
steering wheel position and vehicle
speed of at least 10 km/h (6 mph).
The headlamps shine at an angle of
up to 15 degrees to the right or left
of the direction of travel.
Corner Lighting
On tight bends or when making a
turn, depending on the steering
angle or the turn signal lamp, an
additional left or right reflector is
turned on to illuminate the road at a
right angle to the direction of travel.
It is activated up to a speed of
40 km/h (25 mph).
