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


 Smart Brake Support (SBS)



 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)
The radar sensor (front) functions by detecting the radio waves refl ected off a vehicle ahead
or an obstruction sent from the radar sensor (front).
The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If the Smart Brake Support (SBS) warning light (amber) is illuminated, the area around the
radar sensor (front) may be dirty. Refer to “Warning Guidance” in the centre display (Type
B audio).
Refer to If a Warning Light Turns On or Flashes on page 7-32 .

When Driving
i-ACTIVSENSE
NOTE
  In the following cases, the radar sensor (front) may not be able to detect vehicles ahead
or obstructions.
 


 The rear surface of a vehicle ahead does not refl ect 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 refl ecting radio waves.



 Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tyres and onto your windscreen.
 


 The boot/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. 

 In the following cases, the radar sensor (front) may detect vehicles in the opposite
lane or surrounding obstructions, or it 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 tyres of the same specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signifi cantly different wear patterns or tyre pressures on the same vehicle.
(Including the temporary spare tyre)
  If the battery power is weak, the system may not operate correctly. 
 When driving on roads with little traffi c and few vehicles ahead or obstructions for the
radar sensor (front) to detect, Smart Brake Support/Smart City Brake Support (SBS/
SCBS) warning light (amber) temporarily illuminates, however, this does not indicate
a problem.

When Driving
i-ACTIVSENSE
Laser Sensor (Front) *
The Smart City Brake Support (SCBS) laser sensor (front) is installed at the top of the
windscreen near the rearview mirror.
Laser sensor (front)
Always keep the surface of the windscreen around the laser sensor (front) clean to assure
proper operation of the Smart City Brake Support (SCBS) system.
WARNING
As there is the possibility of eye damage occurring from the laser, always heed the
following precautions:
 
 Never remove the sensor. 
 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.

 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.

When Driving
Parking Sensor System
NOTE
  Do not install any accessories within the detection ranges of the sensors. It may affect
the system operation.
  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.
  The system may not operate normally under the following conditions:




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


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



 The sensor is covered by a hand.



 The sensor is excessively shocked.



 The vehicle is excessively tilted.



 Under extremely hot or cold weather conditions.



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



 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.
 


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



 A commercially-available wing pole or an aerial for a radio transmitter is installed to
the vehicle.
 


 The vehicle is moving towards a tall or square curbstone.



 An obstruction is too close to the sensor. 

 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.
  The following types of obstructions may not be detected:




 Thin objects such as wire or rope



 Things which absorb sonic waves easily such as cotton or snow



 Angular shaped objects



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



 Small, short objects 

 Always have the system inspected at an expert repairer, we recommend an Authorised
Mazda Repairer if any shock is applied to the bumpers, even in a minor accident. If the
sensors are deviated, they cannot detect obstructions.
 (With front sensor and front corner sensor) 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 expert
repairer, we recommend an Authorised Mazda Repairer.
 (Without front sensor and front corner sensor) The system may have a malfunction if the beep does not operate. Consult an expert
repairer, we recommend an Authorised Mazda Repairer.
