*Some models.
Laser Sensor (Front) *
Your vehicle is equipped with a laser sensor (front). The laser sensor (front) is positioned
near the rearview mirror and used by the following systems.
 


y Smart Brake Support (SBS)



y Smart City Brake Support (SCBS)

CAUTION
Heed the following precautions to assure correct operation of the system. 



¾ Keep the windshield clean at all times.



¾ Do not apply stickers to the surface of the windshield (including transparent stickers).



¾ If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front), stop using the system immediately and have your vehicle inspected by an
Authorized Mazda Dealer.
Refer to the Personalization Features on page 9-11 on how to turn off the system.




¾ Do not apply a coating agent to the windshield.



¾ When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.
 


¾ Never remove the sensor.



¾ A removed sensor will not meet the conditions for a class 1M laser under the IEC
60825-1 specifi cation and therefore eye safety cannot be assured.
 


¾ Do not peer into the sensor using optical instruments with a magnifi cation function
such as magnifying glasses, and microscopic and objective lenses within a distance of
100 mm (3.94 in) from the sensor.

*Some models.
Radar Sensors (Rear) *
Your vehicle is equipped with radar sensors (rear). The following systems also use the radar
sensors (rear).
 


y Blind Spot Monitoring system (BSM)



y Rear Cross Traf¿ c Alert (RCTA)
The radar sensors (rear) function by detecting the radio waves reÀ ected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.

Radar sensors (rear)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
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 6-62 .
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.

y 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.
 


y The rear bumper near the radar sensors (rear) has become deformed.



y Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.



y Under bad weather conditions such as rain, snow and fog. 



y Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be dif¿ cult to detect them.




y Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.
 


y Vehicle shapes which do not reÀ ect radar waves well such as empty trailers with a low
vehicle height and sports cars.
 


y 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.
 


y For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorized Mazda Dealer.
 


y 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.
 


y 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.

When Driving
Tire Pressure Monitoring System
*Some models.
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 speci¿ ed
tire pressure (value on the tire pressure label). Follow the procedure and perform the
initialization.
Refer to Tire Pressure Monitoring System Initialization on page 4-154 .
The warning light À ashes when the system has a malfunction.
Refer to Warning Indication/Warning Lights on page 4-33 .

When Driving
Parking Sensor System
*Some models.
Parking Sensor System *
The parking sensor system uses ultrasonic sensors to detect obstructions around the vehicle
while parking the vehicle in a garage or during parallel parking when the selector lever
is in reverse (R). The system is equipped with an assist device to notify the driver of the
approximate distance from the vehicle to the surrounding obstruction using a beep sound
and obstruction detection indication.


Rear corner sensor Rear sensor
WARNING
Do not rely completely on the parking sensor system and be sure to confi rm the safety
around your vehicle visually when driving:
This system can assist the driver in operating the vehicle in the backward directions while
parking. The detection ranges of the sensors are limited, therefore, driving the vehicle
while relying only on the system may cause an accident. Always confi rm the safety
around your vehicle visually when driving.

N O T E
 


y Do not install any accessories within the detection ranges of the sensors. It may affect the
system operation.
 


y Depending on the type of obstruction and the surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.

y The system may not operate normally under the following conditions: 



y Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when
removed).
 


y The sensor area is frozen (Returns to normal operation when the ice is thawed).



y The sensor is covered by a hand.



y The sensor is excessively shocked.



y The vehicle is excessively tilted.



y Under extremely hot or cold weather conditions.



y The vehicle is driven on bumps, inclines, gravel, or grass covered roads.



y Anything which generates ultrasound is near the vehicle, such as another vehicle's
horn, the engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors.
 


y The vehicle is driven in heavy rain or in road conditions causing water-splash.



y A commercially-available fender pole or an antenna for a radio transmitter is installed
to the vehicle.
 


y The vehicle is moving towards a tall or square curbstone.



y An obstruction is too close to the sensor. 



y Obstructions under the bumper may not be detected. Obstructions that are lower than the
bumper or thin which may have been initially detected but are no longer detected as the
vehicle approaches more closely.
 


y The following types of obstructions may not be detected: 



y Thin objects such as wire or rope



y Things which absorb sonic waves easily such as cotton or snow



y Angular shaped objects



y Very tall objects, and those which are wide at the top



y Small, short objects 



y Always have the system inspected at an Authorized Mazda Dealer if any shock is applied
to the bumpers, even in a minor accident. If the sensors are deviated, they cannot detect
obstructions.
 


y The system may have a malfunction if the beep does not operate or the indicator
light does not illuminate when the park assist sensors switch is turned on. Consult an
Authorized Mazda Dealer.
 


y The system may have a malfunction if the beep sound which indicates a system
malfunction is heard and the indicator light À ashes. Consult an Authorized Mazda Dealer.




y The beeper which indicates a system malfunction may not be heard if the ambient
temperature is extremely cold, or mud, ice, or snow adheres to the sensor area. Remove
any foreign material from the sensor area.
 


y When installing a trailer hitch, consult an Authorized Mazda Dealer.
