sensor MAZDA MODEL CX-30 2019 (in English) Repair Manual

¾If cracks or damage caused by flying
gravel or debris is visible around a
rear radar and rear camera, stop
using the SBS-RC system
immediately and have your vehicle
inspected by an expert repairer (we
recommend an Authorised Mazda
Repairer). If the vehicle continues to
be driven with cracks or scratch
marks left around an ultrasonic
sensor, the system may operate
unnecessarily and cause an
unexpected accident.
Refer to Stopping the Smart Brake
Support [Rear Crossing] (SBS-RC)
System Operation on page 4-184.
¾Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) for rear bumper
replacement.
Do not modify the suspension:
If the vehicle height or inclination is
changed, the
SBS-RC system may not
operate correctly because it cannot
detect obstructions correctly.
Do not apply a strong force to a rear
radar and rear camera:
When washing the vehicle, do not
spray highly pressurised water against a
rear radar and rear camera, or rub it
strongly. In addition, do not hit the rear
bumper forcefully when loading and
unloading cargo. Otherwise, the
sensors may not detect obstructions
correctly which could cause the
SBS-RC system to not operate
normally, or it could operate
unnecessarily.
NOTE
xThe SBS-RC system will operate
under the following conditions.
xThe engine is running.
xThe shift lever (manual
transmission vehicle) or the
selector lever (automatic
transmission vehicle) is in the R
(reverse) position.
xi-ACTIVSENSE warning indication/
warning light is not displayed in the
multi-information display.
xThe vehicle speed is under about
10 km/h (6 mph).
xThe vehicle speed of an
approaching vehicle is about 3
km/h (2 mph) or faster.
xThe SBS-R is not turned off.xThe DSC is not malfunctioning.xIn the following cases, the
i-ACTIVSENSE warning indication/
warning light turns on and operation
of the system is stopped. If the
i-ACTIVSENSE warning indication/
warning light remains illuminated,
have the vehicle inspected at an
expert repairer (we recommend an
Authorised Mazda Repairer) as soon
as possible.
xSome problem with the system
including the SBS-RC system.
xA large deviation in the installation
position of a rear side radar sensor
on the vehicle has occurred.
xThere is a large accumulation of
snow or ice on the rear bumper
near a rear side radar sensor.
xDriving on snow-covered roads for
long periods.
xThe temperature near the radar
sensors becomes extremely hot
due to driving for long periods on
slopes during the summer.
xThe battery voltage has decreased.xUnder the following conditions, the
rear side radar sensor cannot detect
target objects or it may be difficult to
detect them.

360° View Monitor*
▼360° View Monitor
The 360°View Monitor consists of the
following functions which assist the
driver in checking the area surrounding
the vehicle using various indications in
the centre display and a warning sound
while the vehicle is being driven at low
speeds or while parking.
xTo p v i e w
The top view displays an image of
the vehicle from directly above on
the centre display by combining the
images taken from the 4 cameras set
on all sides of the vehicle. The top
view displays on the right side
(left-hand drive)/left side
(right-hand drive) of the screen
when the front view or rear view
screen is being displayed. The top
view assists the driver in checking the
area surrounding the vehicle when
the vehicle is moving forward or in
reverse.
xFront view/front wide view
The image from the front of the
vehicle is displayed on the centre
display.
The view from the front assists the
driver in checking the front of the
vehicle by displaying guide lines on
the displayed image taken from the
front of the vehicle.
xSide view
The images taken from the front left
and right sides of the vehicle are
displayed on the centre display.
The side view assists the driver in
checking the front sides of the
vehicle by displaying guide lines on
the displayed image taken from the
front left and right sides of the
vehicle.
xRear view/rear wide view
The image from the rear of the
vehicle is displayed on the centre
display.
The image from the rear assists the
driver in checking the rear of the
vehicle by displaying guide lines on
the displayed image taken from the
rear of the vehicle.
xParking sensor
If there are any obstructions near the
vehicle while the top view/side view
is displayed, an obstruction
detection indication turns on around
the bumper in the centre display.
The parking sensors use ultrasonic
sensors to detect obstructions
around the vehicle when the vehicle
is driven at low speeds, such as
during garage or parallel parking ,
and notifies the driver of the
approximate distance from the
vehicle to the surrounding
obstruction using sound and an
obstruction detection indication.
Refer to Parking Sensor System on
page 4-252.
xFront Cross Traffic Alert (FCTA)
If there is the possibility of a collision
with an approaching vehicle while
the front view/front wide view/side
view is displayed, a warning is
displayed on the centre display.
The Front Cross Traffic Alert (FCTA) is
designed to assist the driver in
checking both sides of the vehicle
when the vehicle starts to drive at an
intersection.
Refer to Front Cross Traffic Alert
(FCTA) on page 4-123.
xRear Cross Traffic Alert (RCTA)
If there is the possibility of a collision
with an approaching vehicle while
the rear view/rear wide view is
displayed, a warning is displayed on
the centre display.
When Driving
i-ACTIVSENSE
*Some models.4-185

The Rear Cross Traffic Alert (RCTA)
uses rear side radar sensor to detect
vehicles approaching from the rear
left and right sides of the vehicle,
and it assists the driver in checking
the rear of the vehicle while reversing
by flashing the Blind Spot Monitoring
(BSM) warning lights and activating
the warning sound.
Refer to Rear Cross Traffic Alert
(RCTA) on page 4-126.

WARNING
Always confirm the safety of the area
around the vehicle with the mirrors
and directly with your eyes when
driving:
The 360°View Monitor is an auxiliary
device which assists the driver in
checking the safety of the area around
the vehicle.
The shooting range of the cameras and
detection range of the sensors are
limited. For example, the areas in black
at the front and rear of the vehicle
image and the seams where each of
the camera images merge are blind
spots where an obstruction may not be
visible. In addition, the extended
vehicle width lines and projected
vehicle path lines are only to be used
as references, and the images on the
screen may differ from the actual
conditions.
CAUTION
¾Do not use the 360°View Monitor
under any of the following
conditions.
¾Icy or snow-covered roads.
¾Tyre chains or a temporary spare
tyre is installed.
¾The front or rear doors are not fully
closed.
¾The vehicle is on a road incline.
¾The door mirrors are retracted.
¾Do not hit the front/rear camera,
front bumper, liftgate, and door
mirrors forcefully. The camera
position or installation angle may
shift.
¾The cameras are waterproof. Do not
disassemble, modify, or remove a
camera.
¾The camera cover is made of hard
plastic, therefore do not apply oil
film remover, organic solvents, wax,
or coating agents. If any such agent
gets on the camera cover, wipe it off
using a soft cloth immediately.
¾Do not rub the camera lens
forcefully, or clean it with an abrasive
or hard brush. Otherwise, it could
scratch the camera lens and
negatively affect the images.
