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 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 Authorised Mazda Repairer.
  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 deviated.
  Do not remove, disassemble, or modify the radar sensor (front).

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