The Forward Sensing Camera (FSC)
includes a function for detecting a soiled
windshield and informing the driver,
however, depending on the conditions, it
may not detect plastic shopping bags, ice
or snow on the windsh ield. In such cases,
the system cannot accurately determine
a vehicle ahead and may not be able to
operate normally. Always drive carefully
and pay attention to the road ahead.

Front Radar Sensor*
▼Front Radar Sensor
Your vehicle is equipped with a front radar
sensor.
The following systems also use the front
radar sensor.

Mazda Radar Cruise Control (MRCC)
Mazda Radar Cruise
Control with Stop
& Go function (MRCC with Stop & Go
function)
Traffic Jam Assist (TJA)
Smart Brake Support (SBS)
The front radar sensor functions by
detecting the radio waves reflected off a
vehicle ahead or an obstruction sent from
the radar sensor.
The front radar sensor is mounted behind
the front emblem.
1. Front radar sensor

If “Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” is displayed on
the multi-information display of the
instrument cluster, clean the area around
the front radar sensor.

Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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 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, disa ssemble, 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 suspension. If the
suspension are modified, 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 co nditions, 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
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 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 co nditions, 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.
When Driving
i-ACTIVSENSE
4-205
Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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 front radar sensor to detect,
“Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” 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.
Front Side Radar Sensor*
▼Front Side Radar Sensor
Your vehicle is equipped with front side
radar sensor. The following systems also
use the front side radar sensor.
Front Cross Traffic Alert (FCTA)
The front side radar sensor function by
detecting the radio waves reflected off a
vehicle approaching from the front or an
obstruction sent from the radar sensor.
1. Front side radar sensor

The front side radar sensor are installed
inside the front bumper, one each on the
left and right sides.
Always keep the surface of the front
bumper near the front side radar sensor
clean so that the front side radar sensor
operate normally. Also, do not apply items
such as stickers.
Refer to Exterior Care on page 6-44.
CAUTION
If the front 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.

may lower and the system may not
operate normally.
The front bumper near the front side
radar sensor has become deformed.
Snow, ice or mud adheres to the front
side radar sensor on the front bumper.
Under bad weather conditions such as

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 front side radar sensor adjusted
for each vehicle to a loaded vehicle
condition so that the front side radar
sensor detect approaching vehicles
correctly. If the direction of the front
side radar sensor has deviated for some
reason, have the vehicle inspected at an
Authorized Mazda Dealer.
For repairs or replacement of the front
side radar sensor, or bumper repairs,
paintwork, and replacement near the
radar sensors, consult an Authorized
Mazda Dealer.
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.
