2021 MAZDA MODEL 3 HATCHBACK Owners Manual

When parking in a space with a division line on only one side of the parking space,
the division line and the vehicle width guide line appear aligned in the monitor,
but they may not actually be aligned on the ground.
▼Variance Between Actual Road Conditions and Displayed Image
Some variance occurs between the actual road and the displayed road. Such
variance in distance perspective could lead to an accident. Note the following
conditions that may cause a variance in distance perspective.
When the vehicle is tilted due to the weight of passengers and load
When the vehicle rear is lowered, the object displayed on the screen appears farther
than the actual distance.

When there is a steep grade behind the vehicle
When there is a steep upgrade (downgrade) behind the vehicle, the object displayed
on the screen appears farther (downgra de: closer) than the actual distance.

Three-dimensional object on vehicle rear
Because the distance guide lines are displayed based on a
flat surface, the distance
to the three-dimensional object displayed on the screen is di fferent from the actual
distance.

When reversing near a three-dimensional object
When reversing near an overhanging object, the vehicle may hit the object even if
the anticipated course line does not contact the object on the screen. The position
of the object displayed on the screen is different from the actual position because
the anticipated course lines on the screen are displayed based on a horizontal road
surface. When backing up near an overhanging object, confirm the rear and
surrounding conditions directly with your eyes.

Parking Sensor System*
▼Pa r k i n g S e n s o r Sys t e m
The parking sensors use ultrasonic sensor
s 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.

1. Front ultrasonic sensor*
2. Front corner ultrasonic sensor*
3. Rear ultrasonic sensor
4. Rear corner ultrasonic sensor
5. Rear side ultrasonic sensor

WARNING
Do not rely completely on the parking sensor system and be sure to con firm the
safety around your vehicl e 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 con firm the safety around your vehicle visually when driving.

CAUTION
Do not install any accessories within the detection ranges of the sensors. It may
a ff ect 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.
NOTE
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 activate d when the ignition is switched ON the
next time.
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, grating, or grass covered roads.Anything which generates ultrasonic wave s 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 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 a sound is not activated or the detection
indication is not displayed even when the parking sensor OFF switch is pressed
and the parking sensor is operable. Have your vehicle inspected by an Authorized
Mazda Dealer.
The system may have a malfunction if th e indicator light does not turn on even
when the parking sensor OFF switch is turned on. Have your vehicle inspected by
an Authorized Mazda Dealer.
The system may have a malfunction if a message 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.
▼ Sensor Detection Range
The sensors detect obstructions within the following range.

1. Front ultrasonic sensor detection range
2. Rear corner/Rear side ultrasonic sensor detection range
3. Rear ultrasonic sensor detection range
4. Front corner ultrasonic sensor detection range
