Daytime Running Lamps

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. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
•
It is still daylight and the ignition is in RUN or
START,
•
the exterior lamp control is in off or AUTO with the
headlamps off, and
•
an automatic transaxle is not in PARK (P) and the
parking brake is released.
When DRL are on, only the front turn signal/parking
lamps will be on. No other exterior lamps will be
on when the DRL are being used. Your instrument
panel won't be lit up either.
When the exterior lamp control is in AUTO and it's dark
enough outside, the DRL will turn off and the low-beam
headlamps at full brightness will turn on. When it's
bright enough outside, the front turn signal lamps will
go off, and the DRL will turn back on. If you start
your vehicle in a dark garage, the automatic headlamp
system will come on immediately. Once you leave
the garage, it will take approximately one minute for the
automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument
panel cluster may not be as bright as usual. Make sure
your instrument panel brightness knob is in the full
bright position. See "Instrument Panel Brightness" under
Interior Lamps on page 3-16 .
Vehicle's sold in the U.S. can turn the DRL off.
To do this, turn the band on the exterior lamp control
to off. Turn the band to this position again to turn
the DRL on.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
