i-ACTIVSENSE*
▼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 driving 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.
▼ Active Safety Technology
Active Safety Technology supports safer
driving by helping the driver to
recognize potential hazards and avert
accidents.

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 center display and a warning sound
while the vehicle is being driven at low
speeds or while parking.
To p v i e w
The top view displays an image of
the vehicle from directly above on
the center 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 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.
Front view/front wide view
The image from the front of the
vehicle is displayed on the center
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.
Side view
The images taken from the front left
and right sides of the vehicle are
displayed on the center 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.
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 4-248.
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 4-124.

Parking Sensor System*
▼Pa r k i n g S e n s o r Sys t e m
The parking sensors use ultrasonic sensor
s which detect obstructions around the
vehicle when the vehicle is driven at low speeds, such as during garage or parallel
parking , and a buzzer sound and detection indicator notify the driver of the
approximate distance from the vehicle to the surrounding obstruction.
WARNING
Do not rely completely on the parking sensor system and be sure to confirm the
safety around your vehicl e visually when driving:
This system can assist the driver in operating the vehicle in the forward and
backward directions while parking. The detection ranges of the sensors are limited,
therefore, driving the vehicle while relying only on the system may cause an
accident. Always confirm the safety around your vehicle visually when driving.
CAUTION

Do not install any accessories within the detection ranges of the sensors. It may
affect the system operation.
 Depending on the type of obstructio n and the surrounding conditions, the
detection range of a sensor may narrow, or the sensors may not be able to detect
obstructions.
 When washing the vehicle, do not spray highly pressurized water against the
sensor area, or rub it strongly. Otherwise, it may not be able to detect obstructions
correctly and the system may not operate normally.
NOTE
When the ignition is switched OFF, the system status before it was turned off is
maintained. For example, if the ignition is switched OFF while the parking sensor
is activated, the system will be activated when the ignition is switched ON the
next time.
The system may not operate normally under the following conditions:
Mud, ice, or snow is adhering to the sensor area (Returns to normal operation
when removed).
The sensor area is frozen (Returns to normal operation when the ice is thawed).The sensor is covered by a hand.The sensor is excessively shocked.The vehicle is excessively tilted.Under extremely hot or cold weather conditions.The vehicle is driven on bumps, inclines, gravel, grating, or grass covered roads.

Anything which generates ultrasonic waves such as another vehicle's horn, the
engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors approaches the vehicle.
The vehicle is driven in heavy rain or in road conditions causing water-splash.A commercially-available fender pole or an antenna for a radio transmitter is
installed to the vehicle.
The vehicle is moving towards a tall or square curbstone, or a steep grade.An obstruction is too close to the sensor.The vehicle is moving towards an uneven wall or stairs.There are multiple obstructions.The vehicle is driven in a place with low ceilings.Obstructions under the bumper cannot be detected. Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or polesThings which absorb sonic waves easily such as cotton or snowAngular shaped objectsVery tall objects, and those which are wide at the topSmall, short objectsAlways have the system inspected at an Authorized Mazda Dealer if any shock is
applied to the bumpers, even in a minor accident. If the sensors are deviated, they
cannot detect obstructions.
The system may have a malfunction if a sound is not activated or the detection
indication is not displayed even when th e parking sensor OFF switch is pressed
and the parking sensor is operable. Have your vehicle inspected by an Authorized
Mazda Dealer.
The system may have a malfunction if the indicator light does not turn on even
when the parking sensor OFF switch is turned on. Have your vehicle inspected by
an Authorized Mazda Dealer.
The system may have a malfunction if a message indicating a system malfunction is
displayed. Have your vehicle inspected by an Authorized Mazda Dealer.
A message may be displayed even when the ambient temperature is extremely
cold, or mud, ice, or snow adheres to the sensor area. Remove any foreign matter
from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.If a Mazda genuine trailer hitch is used, the rear side of the parking sensor system
is automatically turned off.
