Strong light is directed at the front of
your vehicle (such as backlight and
high-beam headlights).
The surrounding area is dark (such as
during the night, early evening, or
early morning, or in a tunnel or
indoor parking lot).
There are light sources in the
surrounding area (such as street
lamps, illuminated signboards, andtraffic signals).
There are objects which reflect light
(such as reflective plates and signs)
in the surrounding area.
The surrounding brightness suddenly
changes (such as when entering or
exiting a tunnel).
The brightness of the headlights of
your vehicle is insufficient (such as
the illumination is weakened due to
a dirty lens or the optical axis is
deviated).
Tires other than the specified size are
used on your vehicle (such as when
tire chains or temporary spare tires
are used).

Foreign matter is stuck to the
windshield (such as ice, fog, snow,
frost, raindrops, dirt, or a piece of
plastic).
The windshield is dirty or fogged.The Forward Sensing Camera (FSC) is
blocked by an obstruction, causing
poor forward visibility (such as when
roof rails are installed to the vehicle
and a long object is loaded).
The windshield washer is being used.The windshield wipers are not used
when it is raining.
Your vehicle is tilted (such as when
heavy luggage is in the luggage
compartment or on the rear seat).

or ascending or descending a steep
slope.
The vehicle is driven on a road with
sharp curves or up and down (wavy)
slopes.

Radar Sensors*
The radar sensor detects objects by
sending radio waves in a specific
direction and receiving the reflected
waves back.

size and the same manufacturer,
brand, and tread pattern on all 4
wheels. In addition, do not use
tires with significantly different
wear patterns or tire pressures on
the same vehicle (including
temporary spare tire).
Do not spray highly pressurized
water against the radar sensors or
rub them strongly.

2. Front camera*
3. Rear camera
CAUTION
Do not disassemble, modify, or
remove a camera.
 Consult an Authorized Mazda Dealer
if you need to repair, replace, or
paint parts near the cameras.

the camera position and the
installation angle may shift. Have
your vehicle inspected by an
Authorized Mazda Dealer.
 Heed the following cautions so that
the cameras can function normally.
 Do not modify the suspensions.
Always use wheels of the specified
size for the front and rear wheels.
Consult an Authorized Mazda
Dealer for tire replacement.
 Do not apply oil film remover,
organic solvents, wax or coating
agents, because the camera cover is
made of hard plastic. If any such
agent is applied, wipe it off using a
soft cloth immediately.
 Do not rub a camera cover forcefully
with an abrasive or hard brush. The

damaged by flying gravel, replace the
camera. For the camera
replacement, consult an Authorized
Mazda Dealer.
 Depending on the type of target
object and surrounding conditions,
the distance at which the camera can
detect target objects may be
shortened or the target objects may
not be detected. Always
confirm the
safety around the vehicle visually
when driving.
NOTE
Do not apply stickers and do not
install accessories or illuminated
number/character license plates to
the area around a camera.
Otherwise, the camera may not
correctly display the surrounding
conditions.
