Lighting 5-3
When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker,
instrument panel lights and other
lamps will not be on.
The DRL turn off when the
headlamps are turned to

Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor located on
top of the instrument panel. Do not
cover the sensor or the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
When it is bright enough outside
the headlamps will turn off or may
change to daytime running
lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
O
or the ignition
is off.
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater road
illumination while turning. To enable
AFL, set the exterior lamp switch
to the AUTO position. Moving the
switch out of the AUTO position
deactivates the system. AFL
operates when the vehicle speed
is greater than 3 km/h (2 mph).
AFL does 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 on page 5‑1.
