▼i-ACTIVSENSE
i-ACTIVSENSE is a collective term
covering a series of advanced safety and
driver support systems which make use of
cameras and sensors. The systems consist
of active safety and pre-crash safety
systems.
These systems are designed to assist the
driver in safer drivi
ng by reducing the load
on the driver and helping to avert
collisions or reduce their severity.
However, because each system has its
limitations, always drive carefully and do
not rely solely on the systems.

Rear Cross Traffic Alert
(RCTA)
*
▼Rear Cross Traffic Alert (RCTA)
The RCTA system is des
igned to assist the
driver in checking the area to the rear left
and right sides of your vehicle while your
vehicle is reversing by alerting the driver
to the presence of vehicles approaching
the rear of your vehicle.
The RCTA system detects vehicles
approaching from the rear left and right
sides of your vehicle and the rear of your
vehicle while your vehicle is being
reversed out of a parking space, and
notifies the driver of possible danger using
the Blind Spot Monitoring (BSM) warning
indicator lights and the warning buzzer.

Rear view/rear wide view
The image from the rear of the vehicle is
displayed on the center 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.
Parking 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 center 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
4-233.
Front 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
center 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 4-109.
Rear Cross Traf fic Alert (RCTA)
If there is the possib ility of a collision
with an approaching vehicle while the
rear view/rear wide view is displayed, a
warning is displayed on the center
display.
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.

WA R N I N G
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 widt h 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
 Do not use the 360°View Monitor under
any of the following conditions.
 Icy or snow-covered roads.
 Tire chains or a temporary spare tire is
installed.
 The front doors or the rear doors is not
fully closed.
 The vehicle is on a road incline.
 The door mirrors are retracted.
 Do not hit the front/rear camera, front/
rear bumper, and door mirrors forcefully.
The camera position or installation angle
may shift.
 The cameras are of a waterproof
structure. Do not di sassemble, modify, or
remove a camera.
 The 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.
 Do 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.
 Consult an Authorized Mazda Dealer for
repair, painting, or replacement of the
front/rear camera, front/rear bumper
and door mirrors.
 Heed the following cautions to assure
that the 360°View Monitor operates
normally.
 Do not modify the vehicle suspensions
or lower/raise the vehicle body, or
both.
 Always use wheels of the
specified type
and size for the front and rear wheels.
Consult an Authorized Mazda Dealer
for tire replacement.
 When the display is cold, images may
leave trails or the screen might be darker
than usual, making it
difficult to check
the vehicle surroundings. Always confirm
the safety at the front and around the
vehicle visually when driving.
 The method for parking/stopping the
vehicle using the 360°View Monitor
differs depending on the road
circumstances/conditions and the
vehicle conditions. When and how much
you turn the steering wheel will differ
depending on the situation, , therefore
always check the vehicle surroundings
directly with your eyes while using the
