Mazda CX-9 Owners Manual: Parking Sensor System

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.

WARNING

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 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.

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 beep 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, consult an Authorized Mazda Dealer.

Sensor Detection Range

The sensors detect obstructions within the following range.

Viewing distance display

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.

Sensor detection condition

The system can be used when the ignition is switched ON and the Park Assist Sensor Switch has been turned on.

The sensors detect obstructions under the following conditions:

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)

Without front sensor and front corner sensor

When the ignition is switched ON and the selector lever is shifted to the reverse (R), the beep sound activates and the system is enabled for use.

The sensors detect obstructions under the following conditions:

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.

Without 360º view monitor

With 360º view monitor

NOTE The detection indicator can switch between display and non-display.

System problem notification

If a problem occurs, the driver is notified of the problem by the following indications.

Parking Sensor Warning Beep

The beeper sounds as follows while the system is operating.

Front Sensor*, Rear Sensor

*1 The rate at which the intermittent sound beeps increases as the vehicle approaches the obstruction.

Front Corner Sensor, Rear Corner Sensor

*1 The rate at which the intermittent sound beeps increases as the vehicle approaches the obstruction.

NOTE If an obstruction is detected in a zone for 6 seconds or more, the beep sound is stopped (except for the close-distance zone). If the same obstruction is detected in another zone, the corresponding beep sound is heard.

When Warning Indicator/Beep is Activated

The system notifies the driver of an abnormality by activating the beep sound and the indicator light.
