the headlights if they are needed immediately when
entering a dark tunnel, parking structure, etc.
The light control sensor is on top of the driver’s side instrument
panel.
Do not place anything on the instrument panel, and / or do not
affix anything on the windshield to block this sensor.
The lights automatically turn off when the driver’s door is
opened with the ignition turned off. To turn them on again, turn
the ignition key to the “ON” position or actuate the headlight
switch. If you are going to park for over one week, make sure
the headlight switch is off.
When the headlight switch is turned to the first or second
clickstop, the brightness of the instrument cluster will be
reduced slightly unless the instrument panel light control knob
is turned fully on.

SWITCHES
17 Daytime Running Light System (Canada only)
The headlights turn on when the parking brake is released with
the engine started, even with the light switch in the “OFF”
position. They will not go off until the ignition switch is turned
off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.
Under the daytime running light system, the headlights turn on
at reduced intensity. Twist the knob to the second clickstop to
turn to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatically adjust to full intensity and / or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE:
To prevent the battery from being discharged, do not
leave the lights on for a long period when the engine is
not running.

For signaling turns, move the lever up or down in the

The turn signal is self-cancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also signal
a lane change by moving the turn signal lever partway and
holding it there. If the green light in the instrument cluster
flashes faster than normal, it indicates that the front or rear turn
signal bulb has burned out. If this indicator light does not come
on, the fuse or the indicator light itself has probably failed. You
may change headlight beam even while the turn signal lights
are flashing.
