Headlamps
The multifunction lever operates the exterior lamps.
O (Exterior Lamps) : Turn the band on the
multifunction lever with this symbol to operate the
exterior lamps.
The exterior lamp band has three positions:
9 (OFF) : Turns off all lamps, except the daytime
running lamps (DRL).
; (Parking Lamps) : Turns on the parking lamps,
together with the following:
. Marker Lamps (unless the vehicle has the marker
and clearance lamps switch)
. Tail Lamps
. License Plate Lamps
. Instrument Panel Lights
2 (Headlamps) : Turns on all the headlamps, together
with the previously listed lamps and lights.
A circuit breaker protects the headlamps. If there is an
electrical overload, the headlamps will flicker on and off.
Have the headlamp wiring checked right away if this
ever happens.
Headlamps on Reminder
For vehicles with this feature, an alarm will sound when
the headlamps and/or parking lamps are turned on and
the ignition is in LOCK/OFF or ACC/ACCESSORY.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
The DRL system will make the headlamps come on at
reduced brightness when the following conditions
are met:
. The ignition is on.
. The headlamp band is in the OFF position.
. The parking brake is released.
When the DRL are on, only the low-beam headlamps
will be on. The exterior lamps and instrument panel will
not be lit.
