2-57 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, do the following:
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. Reinstall 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.
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 lights are required on
all vehicles first sold in Canada.
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 parking brake is
engaged prior to turning the ignition on.
The DRL system will make your front turn signal lamps
come on when:
The ignition is on,
the headlamp switch is OFF,
the parking brake is released, and
it is bright enough outside (on Canadian vehicles).

the handle located inside
the vehicle below the
instrument panel on the
driver's side.
Then go to the front of the vehicle and pull up on the
hood release located at the center of your hood.
Lift the hood.
