When Driving
Start/Stop Engine
NOTE
  If any one of the following occurs, the length of time the engine is stopped
automatically could be shorter or the length of time required before i-stop functions
again could be longer.
 


 The ambient temperature is high or low.



 The battery power is depleted.



 The power consumption of vehicle equipment is high. 

 The i-stop function does not operate when the ambient temperature is extremely high
or low.
  The engine may not stop automatically for a while after the battery leads are
reconnected after temporarily disconnecting them. In addition, if the battery is
replaced, the i-stop system will need to be reset and checked to make sure it operates
correctly. When replacing the battery, consult an expert repairer, we recommend an
Authorised Mazda Repairer.
i-stop OFF Switch
The i-stop function can be turned off by
pressing the switch until the beep sounds
and the i-stop warning light (amber) in the
instrument cluster illuminates. The i-stop
function can be turned back on by pressing
the switch again until the beep sounds and
the i-stop warning light (amber) turns off.
NOTE

When Driving
Start/Stop Engine
Vehicle Roll Prevention Function (Automatic transaxle)
Vehicles with i-stop are equipped with a vehicle roll prevention function. This function
prevents the vehicle from rolling, such as when releasing the brake pedal while on a slope
under the following conditions:
 


 During idling stop (prevents the vehicle from rolling back)



 When starting from a stop (prevents the vehicle's sudden movement due to vehicle creep)
 The braking force is maintained automatically when the brake pedal is released and the
engine is restarted.
Release foot from brake pedal Vehicle brake force maintained
Engine restarted Acceleration

When Driving
Start/Stop Engine
WARNING
The vehicle roll prevention function is a supplementary function which operates for
a maximum of four seconds after releasing the brake pedal when starting the vehicle
after the vehicle is stopped with the i-stop function operating:
 
 Over reliance on the system may result in an unexpected accident if the vehicle were
to suddenly accelerate. Before starting to drive the vehicle, always confi rm the safety
of the surroundings and operate the selector lever, brake pedal, and accelerator
pedal appropriately.
  The vehicle could roll unexpectedly depending on the vehicle's load or if it is towing
something. Note that the vehicle may move suddenly after the vehicle roll prevention
function is released while the vehicle is under the following conditions:
 (The selector lever is in the N position.)  If the selector lever is shifted to the N position and the brake pedal is released while
the i-stop function is operating, the brake force is gradually released. To accelerate
the vehicle, release the brake pedal after the engine restarts and shift the selector
lever to a position other than the N position.
NOTE
  When the vehicle is stopped on a steep grade, the vehicle roll prevention function does
not operate because the idling stop does not operate.
  The brake pedal response may change, sound may occur from the brakes, or the
brake pedal could vibrate from the operation of the vehicle roll prevention function.
However, this does not indicate a malfunction.

  After refuelling, it may require some
time for the indicator to stabilize. In
addition, the indicator may deviate
while driving on a slope or curve
since the fuel moves in the tank.
  The display indicating a quarter
or less remaining fuel has more
segments to show the remaining fuel
level in greater detail.
  The direction of the arrow ()
indicates that the fuel-fi ller fl ap is on
the left side of the vehicle.
(SKYACTIV-D 2.2)
If inconsistency in engine performance
or stalling occurs due to low fuel level
conditions, refuel the vehicle as soon as
possible and add at least 10 L (2.7 US gal,
2.2 Imp gal) of fuel.
