(Canada)
When the headlight switch is in a position other than
and the ignition is switched ON, the
light sensor senses the surr ounding lightness or darkness and automatically turns the
headlights and other exteri or lights on or off.
CAUTION
Do not shade the light sensor by adhering a st icker or a label on the windshield. Otherwise
the light sensor will not operate correctly.
 The light sensor also works as a rain sensor for the auto-wiper control. Keep hands and
scrapers clear of the windshield when the wiper lever is in the
position and the ignition
is switched ON as fingers could be pinched or the wipers and wiper blades could be
damaged when the wipers activa te automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is partic
ularly tempting to leave the
engine running. This is particularly important when clearing ice and snow.
NOTE
The headlights, other exterior lights and dashboard illumination may not turn off
immediately even if th e surrounding area becomes we ll-lit because the light sensor
determines that it is night time if the surrounding area is continuously dark for several
minutes such as inside long tunnels, traffic ja ms inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the
position.
(Without auto headlight off function)
When the headlight switch is in the
position and the ignition is switched to ACC or
the ignition is switched off, the headlights, other exterior lights and dashboard
illumination will turn off.
The dashboard illumination can be adjusted by rotating the knob in the instrument cluster.
Also, the day/night mode can be changed by rotating the knob until a beep sound is heard.
To adjust the brightness of the dashboard illumination:
Refer to Dashboard Illumination on page 4-14.
