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.

When Driving




2017-4-7 11:59:21

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

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 could

change and the radar sensor (front) may not be able to correctly detect a vehicle ahead or
an obstruction.


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 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




2017-4-7 11:59:21

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.

Radar Sensors (Rear)

Your vehicle is equipped with radar sensors (rear). The following 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)

Radar sensors (rear)

The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
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 6-63.


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.

When Driving




2017-4-7 11:59:21


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.

Tire Pressure Monitoring System


The Tire Pressure Monitoring System (TPMS) monitors the air pressure of all four tires. If
the air pressure of one or more tires is too low, the system warns the driver by indicating the
tire pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tire pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specified
tire pressure (value on the tire pressure label). Follow the procedure and perform the
Refer to Tire Pressure Monitoring System Initialization on page 4-148.
The warning light flashes when the system has a malfunction.

Tire Pressure Monitoring System


*Some models.


2017-4-7 11:59:21


Each tire, including the spare (if provided), should be checked monthly when cold and

inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

To avoid false readings, the system samples for a little while before indicating a problem. As

a result it will not instantaneously register a rapid tire deflation or blow out.

Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases:

The size, manufacturer, or the type of tires is different from the specification.

The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them.

A run-flat tire, studless tire, snow tire, or tire chains are used.
