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.

NOTE
The detection ability of the front side
radar sensor has limitations. In the
following cases, the detection ability
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
rain, snow and fog.
Under the following conditions, the front
side radar sensor cannot detect target
objects or it may be difficult to detect
them.
Stationary objects on a road or a road
side such as small, 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 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.

▼Rear Side Radar Sensor
Your vehicle is equipped with rear side
radar sensor. The following systems also
use the rear side radar sensor.
Blind Spot Monitoring (BSM)
Rear Cross Traffic Alert (RCTA)
Smart Brake Support [Rear Crossing]
(SBS-RC)
The rear side radar sensor function by
detecting the radio waves reflected off a
vehicle approaching from the rear or an
obstruction sent from the radar sensor.

The rear side radar sensor are installed
inside the rear bumper, one each on the
left and right sides.
Always keep the surface of the rear
bumper near the rear side radar sensor
clean so that the rear side radar sensor
operate normally. Also, do not apply items
such as stickers.
Refer to Exterior Care on page 6-43.
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.

Vehicle Loading
▼Vehicle Loading
WA R N I N G
Do not tow a trailer with this vehicle:
Towing a trailer wi
th this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so will
affect the drive system which could result in
vehicle damage.
This section will guide you in the proper
loading of your vehicle, to keep your
loaded vehicle weight within its design
rating capability. Properly loading your
vehicle will provide maximum return of
vehicle design performance. Before
loading your vehicle, familiarize yourself
with the following terms for determining
your vehicle's weight ratings, from the
vehicle's Safety Certification Label and
Tire and Load Information Label:
WA R N I N G
Overloaded Vehicle:
Overloading a vehicle is dangerous. The
results of overloading can have serious
consequences in terms of passenger safety.
Too much weight on a vehicle's suspension
system can cause spring or shock absorber
failure, brake failure, handling or steering
problems, irregular tire wear, tire failure or
other damage.
Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases of
serious overloading, brakes can fail
completely, particularly on steep grades.
The load a tire will carry safely is a
combination of the size of the tire, its load
range, and corresponding inflation
pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings from
the vehicle's Safety Certification and Tire
and Load Information labels.
Base Curb Weight is the weight of the
vehicle including a f ull tank of fuel and
all standard equip ment. It does not
include passengers, cargo, or optional
equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it up
from your dealer plus any aftermarket
equipment.

Steps for Determining the Correct Load Limit
▼Steps for Determining the Correct Load Limit
Steps for Determining Correct Load Limit-
(1) Locate the statement “The com
bined weight of occupants and cargo should never
exceed XXX kg or XXX lbs.” on your vehicle's placard.
(2) Determine the combined weight of the driver and passengers t hat will be riding in your
vehicle.
(3) Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo an d luggage load capacity. For
example, if the “XXX” amount equ als 1400 lbs. and there will be five 150 lb passengers
in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs.
(1400 － 750 (5 × 150) = 650 lbs.)
(5) Determine the combined weight of luggage and cargo being loa ded on the vehicle. That
weight may not safely exceed the available cargo and luggage lo ad capacity calculated
in Step 4.
(6) If your vehicle will be towi ng a trailer, load from your trailer will be transferred to your
vehicle. Consult this manual to determine how this reduces the available cargo and
luggage load capacity of your vehicle.
