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.

When Driving
i-ACTIVSENSE
NOTE
  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 diffi cult 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 refl ect 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 Authorised Mazda Dealer.
  For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork,
and replacement near the radar sensors, consult an Authorised 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.

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.
  The system may have a malfunction if the beep does not operate. Consult an expert
repairer, we recommend an Authorised Mazda Repairer.
  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.
  When installing a trailer hitch, consult an expert repairer, we recommend an
Authorised Mazda Repairer.

Audio System
NOTE
  To prevent the battery from being
discharged, do not leave the audio
system on for a long period of time
when the engine is not running.
  If a cellular phone or CB radio is
used in or near the vehicle, it could
cause noise to occur from the audio
system, however, this does not
indicate that the system has been
damaged.
Do not spill any liquid on the audio
system.
Do not insert any objects, other than CDs,
into the slot.
Radio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere.
Therefore, they can reach longer distances
than FM signals.
Because of this, two stations may
sometimes be picked up on the same
frequency at the same time.
Station 2 Station 1Ionosphere
FM characteristics
An FM broadcast range is usually about
40—50 km (25—30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM.

Interior Features
Audio System
Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.

Operating Tips for CD Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in
the CD player may become clouded with
condensation. At this time, the CD will
eject immediately when placed in the unit.
A clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about
an hour. Wait for normal operation to
return before attempting to use the unit.
Handling the CD player
The following precautions should be
observed.
 


 Do not use deformed or cracked CDs.
The disc may not eject resulting in a
malfunction.
 


 Do not use non-conventional discs such
as heart-shaped, octagonal discs, etc.
The disc may not eject resulting in a
malfunction.
