Pull the knob toward you to the first setting to turn on
the parking lamps and other operating lamps without the
headlamps. Pull the knob toward you to the second
setting to turn on the headlamps as well as the other
operating lamps.

Turn the knob from left to right to control brightness of
the instrument panel lights.

If the headlamp switch is left on, you’ll hear a warning
chime when you turn the ignition off, remove the key
from the ignition and open the driver’s door.

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 high

-

beam headlamps

come on at reduced brightness in daylight when:
D the ignition is on,
D the headlamp switch is off and
D the transaxle is not in PARK (P).
When DRL are on, only your high

-

beam headlamps will

be on. The parking lamps, 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 high

-

beam

headlamps will turn off and your low

-

beam and parking

lamps will become active. The other lamps that come on
with your headlamps will also come on. When it’s bright
enough outside, the regular lamps will go off, and your
high

-

beam headlamps change to the reduced brightness

of DRL.
