
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.
The system may have a malfunction if the beep does not operate or the indicator light

Mazda Dealer.
The system may have a malfunction if the beep sound which indicates a system
