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 AUTO position and the
ignition is switched ON as fingers 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 and other exterior lights 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, traffic jams inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the OFF position.
If the headlight switch and the windshield wiper switch are in AUTO, and the wipers are

operated at low or high speed by the auto wiper control for several seconds, bad weather
conditions are determined and the headlights may be turned on.
The sensitivity of the auto-light control may be changed.

Refer to the Settings section in the Mazda Connect Owner's Manual.
