Vehicle Roll Prevention Function (Automatic transaxle)
Vehicles with the i-stop function 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:
 


 While engine idling is stopped (prevents the vehicle from rolling back)



 When the engine restarts after releasing the brake pedal (prevents the vehicle's sudden
movement due to vehicle creep), sudden movement of the vehicle is prevented by
controlling the brakes or the automatic transaxle.

When Driving
Start/Stop Engine
WARNING
Do not rely completely on the vehicle roll prevention function.
The vehicle roll prevention function is a supplementary function which operates for a
maximum of four seconds after releasing the brake pedal and accelerating the vehicle
from an engine idling stop condition. 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. Note that the vehicle may move
suddenly 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 engine idling is not stopped.
  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.

Instrument Cluster and Display
Current fuel economy mode
This mode displays the current fuel
economy by calculating the amount of fuel
consumption and the distance travelled.
Current fuel economy will be calculated
and displayed every 2 seconds.
When you've slowed to about 5 km/h (3
mph), - - - L/100 km (- - - mpg) will be
displayed.
Tachometer *
The tachometer shows engine speed in
thousands of revolutions per minute (rpm).
CAUTION
Do not run the engine with the
tachometer needle in the RED ZONE.
This may cause severe engine damage.

When Driving
Instrument Cluster and Display
NOTE
When the tachometer needle enters the
STRIPED ZONE, this indicates to the
driver that the gears should be shifted
before entering the RED ZONE.
Fuel Gauge
The fuel gauge shows approximately
how much fuel is remaining in the tank
when the ignition is switched ON. We
recommend keeping the tank over 1/4 full.
Full
1/4 Full
Empty
If the low fuel warning light illuminates or
the fuel level is very low, refuel as soon as
possible.
Refer to Warning/Indicator Lights on page
4-36 .
NOTE
  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 1.5)
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.
Instrument panel Illumination
When the position lights are turned
on with the ignition switched ON,
the brightness of the instrument panel
illumination is dimmed.
NOTE
When the position lights are turned on,
the position lights indicator light in the
instrument cluster turns on.
