If you pull the knob out
halfway, it will turn on only
your parklamps. If you pull
the knob all the way out,
your headlamps will then
come on.
Push the knob in all the way to turn off the lamps.
A warning chime will sound if you open
the
driver's
door when you turn the ignition switch to OFF, LOCK
or ACC with the lamps on.

Headlamp Control
Daytime Running Lamps (DRL)
can
make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't covered.
The DRL system will make your front turn signal lamps
come on when:
0
The ignition is on,
0
The headlamp switch is off and
0
The parking brake is released.
When the DRL are on, only your front turn signal lamps
will be on. The headlamps, taillamps, sidemarker and
other lamps won't be on. Your instrument panel won't
be lit up either.
When it's dark enough outside, your front turn signal
lamps will turn off and your vehicle's headlamps and
parklamps will turn on. The other lamps that come on
with your headlamps will also come on.
When it's bright enough outside, your headlamps will go
off and your front turn signal lamps will come on.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your vehicle. The DRL, headlamps and parklamps will
stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.
