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 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 automaticall y. If you are going to clean the windshield,
be sure the wipers are turned off completely wh en 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, traffic jams inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the li ght 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.

Auto-wiper control*
When the wiper lever is in the AUTO
position, the rain sensor senses the amount
of rainfall on the windshield and turns the
wipers on or off automatically
(off―intermittent―low speed―high
speed).

The sensitivity of the rain sensor can be
adjusted by turning the switch on the
wiper lever.
From the center position (normal), rotate
the switch upward for higher sensitivity
(faster response) or rotate it downward for
less sensitivity (slower response).

Higher sensitivity
Less sensitivitySwitch

position
CAUTION
 Do not shade the rain sensor by adhering
a sticker or a label on the windshield.
Otherwise the rain sensor will not
operate correctly.
 When the ignition is switched ON and
the wiper lever is in the AUTO position,
the windshield wipers may operate
automatically in the following cases:
 The area of the windshield above the
rain sensor is touched or wiped with a
cloth.
 The windshield or the rain sensor area
in the cabin is hit.
When the ignition is switched ON and
the wiper lever is in the AUTO position,
do not touch the windshield or the
windshield wipers Otherwise, the
windshield wipers will operate
automatically which could catch your fingers or damage the windshield wipers.
When removing ice or snow, or cleaning
the windshield, always make sure the
wiper lever is in the OFF position.
NOTE
Switching the auto-wiper lever from the
OFF to the AUTO position while driving
activates the windshield wipers once,
after which they ope rate according to
the rainfall amount.
The auto-wiper control may not operate
when the rain sensor temperature is
about
－10 °C (14 °F) or lower, or
about 85 °C (185 °F) or higher.
If the windshield is coated with water
repellent, the rain sensor may not be
able to sense the amount of rainfall
correctly and the auto-wiper control
may not operate properly.

If dirt or foreign matter (such as ice or
matter containing salt water) adheres to
the windshield above the rain sensor, or
if the windshield is iced, it could cause
the wipers to move automatically.
However, if the wipers cannot remove
this ice, dirt or foreign matter, the
auto-wiper control will stop operation.
In this case, set the wiper lever to the
low speed position or high speed
position for manual operation, or
remove the ice, dirt or foreign matter by
hand to restore the auto-wiper
operation.
If the auto-wiper lever is left in the
AUTO position, the wipers could
operate automatically from the effect of
strong light sources, electromagnetic
waves, or infrared light because the rain
sensor uses an optical sensor. It is
recommended that the auto-wiper lever
be switched to the OFF position other
than when driving the vehicle under
rainy conditions.
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 auto-wiper control functions can be
turned off. Refer to the Settings section
in the Mazda Connect Owner's Manual.
