Diesel Particulate Filter (SKYACTIV-D 2.2)
Diesel Particulate Filter
(SKYACTIV-D 2.2)
The diesel particulate fi lter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
fi lter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate fi lter indicator light may
illuminate under the following conditions:
 


 If the vehicle is driven at 15 km/h (9
mph) or less continuously.
 


 If the vehicle is repeatedly driven for a
short period of time (10 minute or less)
or driven while the engine is cold.
 


 If the vehicle is idled for a long time.
NOTE
The engine sound and exhaust gas smell
may change when PM is being removed
while driving.
Diesel Particulate Filter Indicator Light
When illuminated
The particulate matter (PM) cannot be
removed automatically and the amount of
collected PM reaches a specifi ed amount.
After the engine has suffi ciently warmed
up (engine coolant temperature of 80 °C
or more), depress the accelerator pedal and
drive the vehicle at a speed of 20 km/h
or more for about 15 to 20 minutes to
eliminate the PM. When fl ashing
Contact an expert repairer, we recommend
an Authorised Mazda Repairer.
CAUTION
If the vehicle is continually driven as
usual with the diesel particulate fi lter
indicator light illuminated, PM increases
and the indicator light may start fl ashing.
If the diesel particulate fi lter indicator
light starts fl ashing, have the vehicle
inspected immediately at an expert
repairer, we recommend an Authorised
Mazda Repairer. If the vehicle is not
inspected and continues to be driven, the
engine may malfunction.
NOTE
When the diesel particulate fi lter
indicator light fl ashes, the engine
output is restricted to protect the diesel
particulate fi lter.

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

Interior Features
Air-Conditioning System
Operating Tips
 












 Operate the air-conditioning system with
the engine running.
 


 To prevent the battery from being
discharged, do not leave the fan control
dial on for a long period of time with the
ignition switched ON when the engine is
not running.
 


(With i-stop)
 The airfl ow amount may decrease
slightly while the i-stop function is
operating.
 


 Clear all obstructions such as leaves,
snow and ice from the bonnet and the
air inlet in the cowl grille to improve the
system effi ciency.




 Use the air-conditioning system to defog
the windows and dehumidify the air.
 


 The recirculate mode should be used
when driving through tunnels or while in
a traffi c jam, or when you would like to
shut off outside air for quick cooling of
the interior.
 


 Use the outside air position for
ventilation or windscreen defrosting.
 


 If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then
run the air-conditioning system.
(With A/C switch)
 




 Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
 


 Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
effi cient.

 The refrigerant specifi cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before refi lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
  For details, consult an expert repairer,
we recommend an Authorised Mazda
Repairer.
