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.
