The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If “Front Radar Sensor Blocked” is displa yed in the multi-information display of the
instrument cluster, clean the area around the radar sensor (front).
CAUTION
Heed the following precautions to assu re correct operation of each system.
 Do not adhere stickers (including transparent stickers) to the surface of the radiator grille
and front emblem in and around the radar sensor (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 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 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

out of a parking space. Otherwise, the radar sensor (front) could be hit and its position
deviated.
 Do not remove, disassemble, or mo dify the radar sensor (front).
 For repairs, replacement or paint work ar ound 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 casting 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).
