When Driving
Start/Stop Engine
i-stop *
The i-stop (idling stop) function automatically stops the engine when the vehicle is stopped
at a traffi c light or stuck in traffi c after the engine has been warmed up (SKYACTIV-G 1.5
, SKYACTIV-G 2.0) or other times when the engine is not cold (SKYACTIV-D 2.2), and
then restarts the engine automatically to resume driving. The system provides improved fuel
economy, reduced exhaust gas emissions, and eliminates idling noise while the engine is
stopped.
The driver is notifi ed of a system malfunction or the operation conditions by the i-stop
warning light (amber), i-stop indicator light (green), i-stop warning beep, and control status
display.

When Driving
Start/Stop Engine
NOTE
To ensure safe and comfortable use of the vehicle, the i-stop function controls engine stop

driver, such as the vehicle's interior and exterior environment, and the operational status
of the vehicle.
 
 The engine stops automatically when all of the following conditions are met:




 The engine has been started and the vehicle is driven for a certain period. The i-stop
function will not operate if the vehicle is not fi rst driven, no matter how long the
engine is left idling. Also, after the vehicle is driven for a certain period and then

When Driving
Start/Stop Engine
NOTE
(Automatic transaxle)
 


 The selector lever is in the D/M position (not second gear fi xed mode) or the N
position.
 


 The automatic transaxle fl uid has warmed up suffi ciently.



 The automatic transaxle fl uid temperature is not abnormally high.



 The steering wheel is positioned so that the wheels are pointed nearly straight ahead
(if force is applied to the steering wheel even with the wheels pointed straight ahead,
the i-stop function may not operate. Loosen your grip on the steering wheel to allow
the i-stop function to operate).
 


 The brake pedal is depressed to stop the vehicle (if the i-stop indicator light (green)
fl ashes without the i-stop function operating, it is possible that the brake pedal
has not been depressed suffi ciently. Depress the brake pedal a little more strongly
(except European model)).
 


 Emergency braking is not applied.



 The vehicle is not stopped on a steep grade in a place such as a multilevel car
parking facility.
 


(SKYACTIV-D 2.2)
 The fuel injection learning, which occurs periodically and automatically, is not
performed.


 If any one of the following conditions occurs, extra time may be required for the
engine to stop automatically.
 


 Battery power is depleted as a result of not using the vehicle for a long period.



 The ambient temperature is high or low.



 The battery leads have been disconnected for battery replacement and then
reconnected.
 


(SKYACTIV-D 2.2)
 Particulate Matter (PM) is eliminated by the diesel particulate fi lter. 

 For safety reasons, if any one of the following operations is performed after the engine
has been automatically stopped, the i-stop warning light (amber) illuminates and the
engine will not restart automatically even if the clutch pedal is depressed (manual
transaxle) or the brake pedal is released (automatic transaxle). If this occurs, use the
standard engine starting procedure to start the engine.
 


 The bonnet is opened.



 The driver intends to get out of the vehicle (driver's seat belt is unfastened and
driver's door is opened).

When Driving
Start/Stop Engine
NOTE
 (Automatic transaxle) If the selector lever is shifted from D/M position (not second gear fi xed mode) to the
N position or from the D/M position (not second gear fi xed mode) to the P position
while the i-stop function is operating, the engine will not restart automatically even
if the brake pedal is released. The engine will restart if the brake pedal is depressed
again or the selector lever is shifted to the D/M position (not second gear fi xed mode)
or the R position. In addition, when the driver intends to get out of the vehicle while
the shift lever is in the N or P position (the driver's seat belt is unfastened and the door
is opened), the engine restarts (except European model). (For the purpose of safety,
always keep the brake pedal depressed when shifting the selector lever while the i-stop
function is operating.)

  If any one of the following operations is performed after the engine has been
automatically stopped (shift lever is in neutral position for vehicles with manual
transaxle), the engine will restart automatically even though the clutch pedal is not
depressed (manual transaxle) or the brake pedal is not released (automatic transaxle).
However, for safety reasons, if the shift lever is in a position other than neutral for
vehicles with manual transaxle, the engine will not restart automatically.
 


 The i-stop OFF switch is pressed for several seconds.



(Dual-zone automatic air-conditioning)
 The temperature setting dial of the air conditioning is set to maximum heating/
maximum cooling (A/C ON).
 


 The windscreen defroster switch is on.

 The accelerator pedal is depressed while the selector lever is in the D/M position
(not second gear fi xed mode).




 The selector lever is shifted to the R position.



 The selector lever is shifted from the N or P position to the D/M position (not second
gear fi xed mode).




 The steering wheel is operated with the selector lever in the D/M position (not
second gear fi xed mode).




 The selector lever is in the M position, second gear fi xed mode. 

 If any one of the following vehicle conditions occur after the engine has been
automatically stopped (shift lever is in neutral position for vehicles with manual
transaxle), the engine will restart automatically even though the clutch pedal is not
depressed (manual transaxle) or the brake pedal is not released (automatic transaxle).
However, for safety reasons, if the shift lever is in a position other than neutral for
vehicles with manual transaxle, the engine will not restart automatically.

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.
