CAUTION
The front of the vehicle swings out wide wh en turning the steering wheel while reversing.
Maintain sufficient distance betwee n the vehicle and an obstruction.
 The parking sensor detection range has limita tions. For example, obstructions closing in
from the side and objects short in height may not be detected. Always confirm the safety
around the vehicle vi sually when driving.
For details, refer to the parking sensor obstruction detection indication and warning sound.
Refer to Parking Sensor System on page 4-220.
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 parking 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 widt h 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 steering operation is reversed.

Margin of Error Between Road Sur
face on Screen and Actual Road Surface
There might be some margin of error between the road surface ap pearing on the screen and
the actual road surface. A margi n of error in the perceived distance could lead to an
accident, therefore be aware of the following conditions which can more easily produce
errors in the perceived distance.

The vehicle tilts due to weig ht of passengers and cargo.
If the vehicle is tilted, obstructions picked up by a camera ca n appear farther or closer than
the actual distance from the vehicle.

Radar Sensor (Front)*
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
Distance Recognition Support System (DRSS)
Mazda Radar Cruise Control with Stop & Go function (MRCC with S top & Go function)
Smart Brake Support (SBS)
The radar sensor (front) functions by detecting the radio waves reflected off a vehicle ahead
or an obstruction sent from the radar sensor.
The radar sensor (front) is mo unted behind the front emblem.
Radar sensor (front)
If “Front Radar Sensor Blocked” is displayed in the multi-infor mation display of the
instrument cluster, clean the ar ea around the radar sensor (front).
CAUTION
Heed the following precautions to a ssure correct operation of each system.
 Do not adhere stickers (including transparent st ickers) to the surface of the radiator grille
and front emblem in and around the radar sens or (front), and do not replace the radiator
grille and front emblem with any product that is not a genuine product designed for use
with the radar sensor (front).
 The radar sensor (front) includes a function fo r 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 sh opping bags, ice or snow. If this occurs, the
system may not operate correctly, therefore al ways keep the radar sensor (front) clean.
 Do not install a grille guard.
 If the front part of the vehicle has been dama ged in a vehicle accident, the position of the
radar sensor (front) 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 vehi cles or obstructions such as when pulling
out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or modify the radar sensor (front).
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorized Mazda Dealer.
 Do not modify the suspension. If the suspensi on are modified, the vehicle's posture could
change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.
NOTE
Under the following conditions, the radar sensor (front) 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 effectively, 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 reflecting radio waves.
Visibility is reduced due to a vehicle ahead ca sting off water, snow, or sand from its tires
and onto your windshield.
The 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 radar sensor (front) 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.
Roads with repeated up and down slopes
Driving on poor roads or unpaved roads.
The distance between your vehicle and the vehicle ahead is extremely short.
A vehicle suddenly comes close such as by cutting into the lane.
To prevent incorrect operation of the system, use tires of the same specified size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires
with significantly different wear patterns or tire pressures on the same vehicle (Including
the temporary spare tire).
If the battery power is weak, the system may not operate correctly.

When driving on roads with little traffic and few vehicles ahead or obstructions for the
radar sensor (front) to detect, “Front Radar Sensor Blocked” may be temporarily
displayed, however, this does not indicate a problem.
The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.

Radar Sensors (Rear)*
Your vehicle is equipped with radar sensors (rear). The followi ng systems also use the radar
sensors (rear).
Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.
Radar sensors (rear)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Always keep the surface of the rear bumper near the radar sensors (rear) clean so that the
radar sensors (rear) operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care on page 6-57.
CAUTION
If the rear bumper receives a severe impact, the system may no longer operate normally. Stop
the system immediately and have the vehicle inspected at an Authorized Mazda Dealer.
NOTE
The detection ability of the radar sensors (rear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
The rear bumper near the radar sensors (rear) has become deformed.
Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.
Under bad weather conditions such as rain, snow and fog.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.

Vehicle shapes which do not reflect radar waves well such as empty trailers with a low
vehicle height and sports cars.
Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an Authorized Mazda Dealer.
For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork, and
replacement near the radar sensors, consult an Authorized Mazda Dealer.
Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will
be blocked causing the system to not operate normally.
The radar sensors are regulated by the relevant radio wave laws of the country in which
the vehicle is driven. If the vehicle is driven abroad, authorization from the country in
which the vehicle is driven may be required.
