CAUTION
Heed the following precautions to assure 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 always keep the radar sensor
(front) 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 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 vehicles 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 suspension are modified, the vehicle's posture

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 trunk/luggage compartment is loaded with heavy objects or the r ear 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 str ong radio waves.
 Under the following conditions, the radar sensor (fr ont) 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 damag\
e. Roads with repeated up and down slopes Driving on poor r oads or unpaved roads. The distance between your vehicle and the vehicle ahead is extr emely 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. If the vehicle is driven on a road with little traffic and few vehicles ahead or obstructions
for the radar sensor (front) to detect, the sensor detects that the radar sensor (front) is
dirty and the Smart Brake Support/Smart City Brake Support (SBS/SCBS) \
Warning Light
(amber) may be temporarily turned on. However, it does not indicate a malfunction.

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 (r ear) 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.
