Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off. The
wiper-activated headlamps also turn off if the windshield
wipers are turned off.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so be
sure it is not covered.
The DRL system makes the low-beam headlamps turn
on at reduced brightness in daylight when the following
conditions are met:
. The ignition is on with the engine running.
. The exterior lamp button for the headlamps is off.
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn on
with the headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and the
low-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when the vehicle
is parked, turn the exterior lamp control to the off
position. See Exterior Lamps on page 4‑10 for more
information.
The regular headlamp system should be turned on
when needed.
