▼ Dashboard Illumination
When the lights are turned on with the
ignition switched ON, the brightness of
the dashboard illumination is dimmed.
However, when the light sensor
detects that the surrounding area is
bright such as when the lights are
turned on in the daytime, the
dashboard illumination does not dim.
NOTE
When the ignition is switched ON in
the early evening or at dusk, the
dashboard illumination is dimmed
for several seconds until the light
sensor detects the brightness of the
surrounding area, however, the
dimming may cancel after the
brightness is detected.
When the lights are turned on, the
lights-on indicator light in the
instrument cluster turns on.
Refer to Headlights on page 4-42.

Auto-light control*
When the headlight switch is in a position other than and the ignition is
switched ON, the light sensor senses th e surrounding lightness or darkness and
automatically turns the headlights and other exterior lights on or off.
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 en gine 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 cont inuously dark for several minutes such as
inside long tunnels, traffic jams inside tunnels, or in indoor parking lots.
If the headlight switch and the windshie ld 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.

*1 When the wiper lever is switched to theAUTO position, the indicator light turns on.
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 (+ direction)
for higher sensitivity (faster response)
or rotate it downward (- direction) for
less sensitivity (slower response).

1. Switch
2. Higher sensitivity
3. Center position
4. Less sensitivity
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 wiper lever is in the AUTO
position and the ignition is switched
ON, the wipers may move
automatically in the following cases:
 If the windshield above the rain
sensor is touched or wiped with a
cloth.
 If the windshield is struck with a
hand or other object from either
outside or inside the vehicle.
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 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
most likely that the engine is left
running) this is particularly important
when clearing ice and snow.

NOTE
Switching the auto-wiper lever from
the OFF to the AUTO position while
driving activates the windshield
wipers once, after which they
operate 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.
▼ Windshield Washer
Pull the wiper lever toward you to
spray washer fluid and operate the
windshield wipers several times. The
washer fluid is sprayed only while the
windshield wipers move out of their
stowed positions to the point where
they start reversing back.

1. OFF
2. Washer
NOTE
If the windshield washer is turned on
when the windshield wipers are not
operating, the windshield wipers
operate a few times.
If you pull the wiper lever while the
windshield wipers are reversing back
to their stowed positions, the next
time the washer fluid is sprayed is
during the next cycle.
If the washer does not work, inspect
the fluid level (page 6-19). If the fluid
level is normal, consult an Authorized
Mazda Dealer.
