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 the 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 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 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 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.
