Ultrasonic Sensors
Ultrasonic Sensors
The ultrasonic sensors detect objects
by sending ultrasonic waves in a
specific direction and receiving the
reflected waves back.
Front ultrasonic sensors
Rear ultrasonic sensors
Detection ranges of ultrasonic sensors
1. About 50 cm (20 in)
2. About 1 m 50 cm (59 in)
3. About 1 m (39.3 in)
CAUTION
Heed the following cautions so that
the ultrasonic sensors can function
normally.
Do not modify the suspensions.
5-116
*Some models.
Do not spray highly pressurized
*
water against the ultrasonic sensors
or rub them strongly.
Do not apply stickers on the
ultrasonic sensors.
Consult an Authorized Mazda
Dealer if you need to repair,
replace, or paint the bumper.
Depending on the type of target
object and surrounding conditions,
the distance at which the ultrasonic
sensors can detect target objects may
be shortened or the target objects
may not be detected. Always confirm
the safety around the vehicle visually
when driving.
If strong force is applied to parts near
the ultrasonic sensors, the direction
of the ultrasonic sensor may become
deviated and each system may not
operate normally. Stop each system
immediately and have the vehicle
inspected by an Authorized Mazda
Dealer.
NOTE
The ultrasonic sensors include a
function for detecting abnormalities
in the sensor, soiling of the sensor's
front surface, and informing the
driver. If a message appears on the
screen that can be addressed, follow
the directions of the message.
When any of the following
conditions is met, the ultrasonic
sensors may not be able to detect
target objects, and each system may
not operate normally.
Target object is thin such as wire,
rope, or poles.
Target object absorbs waves easily
such as cotton or snow.
Target object has an angular shape.
Target object is tall and wide at the
upper part.
