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.
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 front parking and turn signal lamps
come on in daylight when:
D The ignition is on,
D the headlamp switch is off, and
D the parking brake is released.
When the DRL are on, only your front parking and turn
signal lamps will be on. Your instrument panel won’t be
lit up.
When it’s dark enough outside, the exterior lamps will
come on automatically. When it’s bright enough outside,
the exterior lamps will go out and the DRL will turn on.
Of course, you may still turn on the headlamps any time
you need to.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
the vehicle. 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.
