How to use the projected vehicle path line function
1. (Screen display)
2. (Actual condition)

Make sure that there are no obstructions within the projected vehicle path lines.
Turn the steering wheel so that the projected vehicle path lines travel inside of the
obstruction (A), and drive the vehicle forward until it passes the obstruction.
If the projected vehicle path lines are on an obstruction (B) or outside of the
obstruction (C), the vehicle may contact the obstruction when turning the vehicle
sharply.
CAUTION
 The parking sensor detection range has limitations. For example, obstructions
closing in from the side and objects short in height may not be detected. Always
con firm the safety around the vehicle visually when driving.
For details, refer to the parking sensor obstruction detection indication and
warning sound.
Refer to Parking Sensor System on page 4-238.
 Do not turn the steering wheel any mo re until the vehicle has passed the
obstruction, even if the obstruction is no t visible on the side view image. If the
steering wheel is turned even more, the vehicle may contact the obstruction if it is
turned sharply.

NOTE
Because there might be a difference between the image displayed on the screen,
such as indicated in the following, and the actual conditions when parking, always
check the safety at the rear of the vehicle and the surrounding area directly with
your eyes.
Even though the back end of the park ing space (or garage) displayed on the
screen and distance guide lines appear parallel, they may not actually be
parallel.
When parking in a space with a division line on only one side of the parking
space, even though the division line and the vehicle width guide line appear
parallel, they may not actually be parallel.
The following shows an example of vehicle parking with the steering wheel turned
to the left while backing up the vehicle. When backing into a parking space from
the opposite direction, the st eering operation is reversed.

Do not adhere stickers (including
transparent stickers) to the surface of
the radiator grille and front emblem
in and around the front radar sensor,
and do not replace the radiator grille
and front emblem with any product
that is not a genuine product
designed for use with the front radar
sensor.
 The front radar sensor includes a
function for detecting soiling of the
radar sensor's front surface and
informing the driver, however,
depending on the conditions, it may
require time to detect or it may not
detect plastic shopping bags, ice or
snow. If this occurs, the system may
not operate correctly, therefore
always keep the front radar sensor
clean.
 Do not install a grille guard.
 If the front part of the vehicle has
been damaged in a vehicle accident,
the position of the front radar sensor
may have moved. Stop the system
immediately and always have the
vehicle inspected at an Authorized
Mazda Dealer.
 Do not use the front bumper to push
other vehicles or obstructions such
as when pulling out of a parking
space. Otherwise, the front radar
sensor could be hit and its position
deviated.
 Do not remove, disassemble, or
modify the front radar sensor.
 For repairs, replacement or paint
work around the front radar sensor,
consult an Authorized Mazda Dealer.
 Do not modify the suspensions. If
the suspensions are modi fied, the
vehicle's posture could change and
the front radar sensor may not be
able to correctly detect a vehicle
ahead or an obstruction.NOTE
Under the following conditions, the
front radar sensor may not be able to
detect vehicles ahead or obstructions
correctly and each system may not
operate normally.
The rear surface of a vehicle ahead
does not reflect radio waves
e ff ectively, such as an unloaded
trailer or an automobile with a
loading platform covered by a soft
top, vehicles with a hard plastic
tailgate, and round-shaped
vehicles.
Vehicles ahead with low vehicle
height and thus less area for
re flecting radio waves.
Visibility is reduced due to a
vehicle ahead casting off
water,
snow, or sand from its tires and
onto your windshield.
The trunk/luggage compartment is
loaded with heavy objects or the
rear passenger seats are occupied.
Ice, snow, or soiling is on the front
surface of the front emblem.
During inclement weather such as
rain, snow, or sand storms.
When driving near facilities or
objects emitting strong radio
waves.
Under the following conditions, the
front radar sensor may not be able to
detect vehicles ahead or
obstructions.
The beginning and end of a curve.Roads with continuous curves.Narrow lane roads due to road
construction or lane closures.
The vehicle ahead enters the radar
sensor's blind spot.
The vehicle ahead is running
abnormally due to accident or
vehicle damage.

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.

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
