When Driving
Switches and Controls
CAUTION
Do not shade the light sensor by adhering a sticker 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 fi ngers could be pinched or the wipers and wiper blades could be
damaged when the wipers activate automatically. If you are going to clean the windshield,
be sure the wipers are turned off completely when it is particularly 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 the surrounding area becomes well-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, traffi c jams 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 4-16 .
The sensitivity of the AUTO lights may be changed by an Authorized Mazda Dealer.
Refer to Personalization Features on page 9-12 .
