function. This function prevents the
vehicle from rolling, such as when
releasing the brake pedal while on a
slope under the following conditions:
xWhile engine idling is stopped
(prevents the vehicle from rolling
back)
xWhen 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.

2. Vehicle brake force maintained
3. Engine restarted
4. Acceleration

WARNING
Do not rely completely on the vehicle
roll prevention function.
¾The vehicle roll prevention function
is a supplementary function which
operates for a maximum of 2
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 confirm 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.
¾Note that the vehicle may move
suddenly after the vehicle roll
prevention function is released while
the vehicle is under the following
conditions:
¾The selector lever is in the N
position.
¾If 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
xWhen the vehicle is stopped on a
steep grade, the vehicle roll
prevention function does not
operate because engine idling is not
stopped.
xThe 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.
▼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 efficiency monitor
display.
Refer to the Fuel Efficiency Monitor
section in the Mazda Connect
Owner's Manual.
