Parking Sensor System
Parking Sensor System *
The parking sensor system uses ultrasonic sensors to detect obstructions around the vehicle
while parking the vehicle in a garage or during parallel parking when the vehicle is driven
at a speed of about 10 km/h (6 mph) or less. The system is equipped with an assist device to
notify the driver of the approximate distance from the vehicle to the surrounding obstruction
using a beep sound and obstruction detection indication

WARNING
Do not rely completely on the parking sensor system and be sure to confi rm 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
confi rm the safety around your vehicle visually when driving.

Parking Sensor System
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 wing pole or an aerial 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 but are no longer detected
as the vehicle approaches more closely.
  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 expert repairer, we recommend an Authorised
Mazda Repairer 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 expert
repairer, we recommend an Authorised Mazda Repairer.
 (Without front sensor and front corner sensor) The system may have a malfunction if the beep does not operate. Consult an expert
repairer, we recommend an Authorised Mazda Repairer.

Parking Sensor System
NOTE
 (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 fl ashes. Consult an expert repairer, we
recommend an Authorised Mazda Repairer.
  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 expert repairer, we recommend an
Authorised Mazda Repairer.

Park Assist Sensor System Operation
With front sensor and front corner sensor
The switch can be activated when the ignition is switched ON, the shift 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.
Indicator light
NOTE
If the system is cancelled, it will not restore automatically even when the vehicle speed is
decreased to 10 km/h or less.
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 system will then operate when the shift lever is placed in reverse (R).
The sensors detect obstructions under the following conditions:
Sensor Condition
Front Sensor The shift lever is in any position except reverse (R), and the vehicle speed is about 10
km/h (6 mph) or less.
Front Corner Sensor The vehicle speed is about 10 km/h (6 mph) or less.
Rear Sensor The shift lever is in reverse (R).
Rear Corner Sensor The shift lever is in reverse (R), and the vehicle speed is about 10 km/h (6 mph) or
less.

When Driving
Parking Sensor System
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.
Without front sensor and front corner sensor
When the ignition is switched ON and the shift 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:
Sensor Condition
Rear Sensor The shift lever is in reverse (R).
Rear Corner Sensor The shift lever is in reverse (R), and the vehicle speed is about 10 km/h (6 mph) or
less.
Obstruction Detection Indication (with Front Sensor and Front Corner
Sensor)
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.
