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 ON or START,
•
the exterior lamp control is in OFF or AUTO with the
headlamps off, and
•
an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.

When DRL are on, only your front turn signal 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 will turn on. When it's bright enough
outside, the low-beam headlamps 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
about 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
lever is in the full bright position. See "Instrument Panel
Brightness" under Interior Lamps on page 3-22 .
