2021 MAZDA MODEL CX-9 sensor

Under extremely hot or cold weather conditions.
The vehicle is driven on bumps, inclines, gravel, or grass covered roads.
Anything which generates ultrasound is near the vehicle, 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.
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.
An obstruction is too close to the sensor.
Obstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected may no longer be detected as the
vehicle approaches more closely to the obstruction.
The following types of obstructions may not be detected:
Thin objects such as wire or rope
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 the beep does not operate or the indicator light
does not illuminate when the parking sensor switch is turned on. Consult an Authorized
Mazda Dealer.
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the i ndicator light flashes. Consult an Authorized Mazda Dealer.
The beeper which indicates a system malf unction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.

▼Parking Sensor System Operation
The switch can be activated when the ignition is switched ON, the selector lever is in any
position except reverse (R), and the vehicle
speed is about 10 km/h (6 mph) or less.

When the parking sensor switch is pressed, a beep sound is heard, the obstruction detection
indication is displayed in the audio screen, and the indicator light in the switch illuminates.

NOTE
If the system is cancelled, it will not restor e automatically even when the vehicle speed is
decreased to 10 km/h (6 mph) or less.
When the ignition is switched OFF, the syst em status before it was turned off is
maintained. For example, if th e ignition is switched OFF while the parking sensor is
activated, the system will be activated when the ignition is switched ON the next time.
Sensor detection condition
The system can be used when the ignition is switched ON and the parking sensor switch has
been turned on.
The sensors detect obstructions under the following conditions:
Sensor Condition
Front Ultrasonic Sensor The selector lever is in any position exce
pt reverse (R), and the vehicle speed is
about 10 km/h (6 mph) or less.
Front Corner Ultrasonic
Sensor The vehicle speed is about 10 km/h (6 mph) or less.
Rear Ultrasonic Sensor The selector lever is in reverse (R).
Rear Corner Ultrasonic
Sensor The selector lever is in reverse (R), and the vehicle speed is ab
out 10 km/h (6 mph)
or less.
The system is cancelled under the following conditions:
The parking sensor switch is pressed while the parking sensor is in operation.
The vehicle speed is 10 km/h (6 mph) or more. (Except rear sensor)

▼Obstruction Detection Indication
The position of a sensor which has detected an obstruction is indicated. The gauge
illuminates in different areas depending on the distance to an obstruction detected by the
sensor.
As the vehicle approaches closer to an obstru
ction, the zone in the gauge closer to the
vehicle illuminates.

NOTE
The detection indicator can be switched between display and non-display and the buzzer
volume can be changed.
Refer to the Settings section in the Mazda Connect Owner's Manual.
(Vehicles with 360° View Monitor)
When the detection indicator is set to “Display”, even with the 360° view monitor not
displayed, if a front ultrasonic sensor or a front corner ultrasonic sensor detects an
obstruction, the 360° view monitor switches automatically to display. When an obstruction
is no longer detected, the display switches
to the display before the obstruction was
detected. However, while the 360° view monito r is displayed, it continues to display no
matter if an obstruction is detected or not.
