Headlamp Doors
The headlamp doors are designed to open when you turn
the headlamps on and close when you turn the
headlamps off. The headlamp doors can be opened
without turning on the headlamps by turning the
headlamps on, then turning the switch back to the
parking lamps position.
The headlamp doors should be open when driving in icy
or snowy conditions to prevent the doors from freezing
closed, and when washing the vehicle to help clean
the headlamps.
To open the headlamp doors manually:
1. Open the hood.
2. Remove the plastic cover from the retractor
motor knob.
3. Turn the retractor motor knob counterclockwise until the
headlamp door is fully open. The knob will get harder
to turn when the headlamp door is all the way up.
4. Replace the plastic cover on the retractor motor knob.
To manually close the headlamp doors, turn the lamps
off and turn the retractor motor knob clockwise. If the
headlamp doors aren’t working properly, see your dealer
for help.
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.
For Canadian vehicles, a light sensor on top of the
instrument panel automatically turns the headlamps on,
so be sure it isn’t covered.
The DRL system will not activate if the park brake is
engaged prior to turning the ignition on.
The DRL system will make your front turn signal lamps
come on when:
D the ignition is on,
D the headlamp switch is OFF,
D the parking brake is released and
D it is bright enough outside (on Canadian vehicles).
When the DRL are on, only your front turn signal lamps
will be on. The taillamps, sidemarker and other lamps
won’t be on. Your instrument panel won’t be lit up
either. When you use your turn signals, the front turn
signal and the taillamp of the desired side will flash.
