2020 MAZDA MODEL 3 HATCHBACK sensor

Parking Sensor System*
▼Parking Sensor System
The parking sensors use ultrasonic sensors which detect obstruc
tions 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 a pproximate 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.

CAUTION
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 th e surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
NOTE
The system may not operate norma lly 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 Aut horized 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 indicator light does not turn on even when the
parking sensor switch is turned on. Have your vehicle inspected by an Authorized Mazda
Dealer.
The system may have a malfunction if a me ssage 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.

Operation
When the parking sensor switch is pressed
with the ignition switched ON, the
indicator light turns on.
When the ignition is switched ON with the
parking sensor activated, the indicator
light turns on.
Press the switch again to stop the
operation.
1. Indicator light
NOTE
When the ignition is
switched OFF, the
system status before it was turned off is
maintained. For exampl e, 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.
Operation conditions
The parking sensor system can be used
when all of the foll owing conditions are
met:
The ignition is switched ON.
The parking sensor switch is turned on.
NOTE
(Automatic vehicle)
The detection indicator and buzzer of
the front sensors/front corner sensors do
not operate when the selector lever is in
the P position.
The detection indicator and buzzer
sound do not activate when the parking
brake is applied.

▼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.

▼Parking Sensor Warning Beep
Informs the driver of the approximate distance from the vehicle
to the obstruction using
warning beeps depending on the d istance. If multiple obstructions are detected at the same
time, warning beeps are activated according to the distance to the nearest obstruction. The
warning beeps are activated as follows while the system is oper ating. However, the warning
beeps are not activated while t he seat belt reminder is operati ng.
