2020 MAZDA MODEL CX-9 sensor

Parking Sensor System*
The parking sensors use ultrasonic sensors 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.

WA R N I N G
Do not rely completely on the parking sensor system and be sure to confirm the safety around
your vehicle visually when driving:
This system can assist the driver in operat ing 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.
NOTE
Do not install any accessories within the detection ranges of the sensors. It may affect the
system operation.
Depending on the type of obstruction and the surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
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, 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.
(With front sensor and front corner sensor)
The system may have a malfunction if the b eep does not operate or the indicator light
does not illuminate when the park assist sensors switch is turned on. Consult an
Authorized Mazda Dealer.
(Without front sensor and front corner sensor)
The system may have a malfunction if the beep does not operate. Consult an Authorized
Mazda Dealer.
(With front sensor and front corner sensor)
The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the indicator light flashes. Consult an Authorized Mazda Dealer.
The beeper which indicates a system malfunction 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, c onsult an Authorized Mazda Dealer.

▼Park Assist Sensor System Operation
With front sensor and front corner sensor
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 restore automatically even when the vehicle speed is
decreased to 10 km/h (6 mph) or less.
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.

▼ 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 obstruction, the zone in the gauge closer to the
vehicle illuminates.
