CAUTION
Heed the following cautions to assure the correct operation of the Forward Sensing
Camera (FSC).
 
 Do not remove the Forward Sensing Camera (FSC) cover. 
 Do not place objects on the instrument panel which refl ect light. 
 Do not apply accessories, stickers or fi lm to the windscreen near the Forward Sensing
Camera (FSC). If there are objects in front of the Forward Sensing Camera (FSC) lens,
even a transparent sticker, they will cause the system to not operate correctly.
  Always keep the windscreen glass around the camera clean by removing dirt or
fogging. Use the windscreen defroster to remove fogging on the windscreen.
  When cleaning the windscreen, do not allow glass cleaners or similar cleaning agent to
get on the Forward Sensing Camera (FSC) lens. In addition, do not touch the Forward
Sensing Camera (FSC) lens.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning the interior side of the windscreen around the Forward Sensing Camera
(FSC).
  Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get
dirty. Also, do no take the camera apart. Otherwise, it could result in damage or
malfunction.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer before
performing repairs around the Forward Sensing Camera (FSC).
  The Forward Sensing Camera (FSC) is installed to the windscreen. Consult an expert
repairer, we recommend an Authorised Mazda Repairer for windscreen repair and
replacement.
  When performing repairs around the rearview mirror, consult an expert repairer, we
recommend an Authorised Mazda Repairer.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning of the Forward Sensing Camera (FSC) lens.
  Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area
around it. If strong force is applied, stop using the Lane Departure Warning System
(LDWS) and the High Beam Control System (HBC), and consult an expert repairer,
we recommend an Authorised Mazda Repairer.
  The direction in which the Forward Sensing Camera (FSC) is pointed has been fi nely
adjusted. Do not change the installation position of the Forward Sensing Camera
(FSC) or remove it. Otherwise, it could result in damage or malfunction.

*Some models.4–150
When Driving
i-ACTIVSENSE
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 .

4–152
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.

the cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.

*Some models.4–161
When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System *
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre 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 specifi ed
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-164 .
The warning light fl ashes when the system has a malfunction.
Refer to Warning Lights on page 4-41 .
