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 your low-beam headlamps
come on at a reduced brightness in daylight when
the following conditions are met:
The ignition is on,
the exterior lamp band is in OFF or in the parking
lamp position,
*
the parking brake is released, and
the transaxle is not in PARK (P) on models with an
automatic transaxle only.
This indicator light on your
instrument panel cluster
will come on when the DRL
are on.
A flashing DRL telltale indicates a possible burned out
headlamp, or that the vehicle may need service to repair
a stuck DRL relay.
When the DRL are on, your low-beam headlamps will
be on at a reduced brightness. The taillamps,
sidemarker and other lamps won't be on. Your
instrument panel won't be lit up either.
When you turn the exterior lamp band to the headlamp
position, your low-beam headlamps will come on.
The other lamps that come on with your headlamps will
also come on.
When you turn off the headlamps, the regular lamps will
go off, and your low-beam headlamps will come on to
the reduced brightness.
To idle your vehicle with the DRL off, set the parking
brake. The DRL 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.
