When Driving
i-ACTIVSENSE
NOTE
  The vehicle posture changes depending on the accelerator pedal, brake pedal and
steering wheel operations, which could make it dif¿ cult for the system to recognise an
obstruction, or it could facilitate unnecessary detection. In such cases, the Smart City
Brake Support [Reverse] (SCBS R) may or may not operate.
  The Smart City Brake Support [Reverse] (SCBS R) system will operate under the
following conditions.
 


 The engine is running.



 The change lever (manual transaxle vehicle) or the selector lever (automatic
transaxle vehicle) is in the R (reverse) position.
 


 The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).



 The Smart City Brake Support [Reverse] (SCBS R) is not turned off.



 The DSC is not malfunctioning. 

 The Smart City Brake Support [Reverse] (SCBS R) operates using ultrasonic sensors
(rear) which detect obstructions at the rear by emitting ultrasonic waves and then
receiving the returning waves reÀ ected off the obstructions.

 In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
Smart City Brake Support [Reverse] (SCBS R) may not operate.
 


 The height of the obstruction is low such as low walls or trucks with low loading
platforms.
 


 The height of the obstruction is high such as trucks with high loading platforms.



 The obstruction is small.



 The obstruction is thin such as a signpost.



 The obstruction is positioned away from the centre of the vehicle.

Diesel Particulate Filter (SKYACTIV-D 1.5)
Diesel Particulate Filter
(SKYACTIV-D 1.5)
The diesel particulate ¿ lter collects and
removes most of the particulate matter
(PM) in the exhaust gas of a diesel engine.
PM collected by the diesel particulate
¿ lter is cleared during normal driving,
however, PM may not be removed and the
diesel particulate ¿ 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 speci¿ ed amount.
After the engine has suf¿ 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 À ashing
Contact an expert repairer, we recommend
an Authorised Mazda Repairer.
CAUTION
If the vehicle is continually driven as
usual with the diesel particulate ¿ lter
indicator light illuminated, PM increases
and the indicator light may start À ashing.
If the diesel particulate ¿ lter indicator
light starts À 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 ¿ lter
indicator light À ashes, the engine

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 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.

Interior Features
Air-Conditioning System
O p e r a t i n g T i p s
 












 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 airÀ 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 ef¿ 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 traf¿ 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.
 


 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
ef¿ cient.

 The refrigerant speci¿ cations are
indicated on a label attached to the
inside of the engine compartment. Check
the label before re¿ lling the refrigerant.
If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.
