Engine idling may not stop right after the battery terminals are disconnected. In addition,
if the battery is replaced, the i-stop functions must be veri¿ ed. Consult an expert repairer,
we recommend an Authorised Mazda Repairer.
i-stop Warning Light (Amber)/i-stop Indicator Light (Green)
To ensure safe and comfortable use of the vehicle, the i-stop system constantly monitors the
driver's operations, the vehicle's interior and exterior environment, and the operational status
of the vehicle, and uses the i-stop warning light (amber) and i-stop indicator light (green) to
inform the driver of various cautions and warnings.
NOTE
On vehicles equipped with the centre display, the i-stop operation status is displayed in the
fuel monitor control status display.

Start/Stop Engine
Vehicle Roll Prevention Function (Automatic transmission)
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 transmission.

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 con¿ 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.

The trip meter records the total distance
the vehicle is driven until the meter
is again reset. Return it to “0.0” by
depressing and holding the selector for
one second or more. Use this meter to
measure trip distances and to compute fuel
consumption.
NOTE
 (Vehicles with type B/type C audio) If the fuel economy data is reset
using the fuel economy monitor,
or trip A is reset using the trip
meter when the function which
synchronizes the fuel economy
monitor and the trip meter is on, the
fuel economy data and trip A are
reset simultaneously.
 Refer to Fuel Economy Monitor on
