Ignition Switch
▼Push Button Start Positions
The system operates only when the key
is within operational range.
Each time the push button start is
pressed, the ignition switches in the
order of
off, ACC, and ON. Pressing
the push button start again from ON
switches the ignition
off.
1. Indicator light
2. Push button start
NOTE
xThe engine starts by pressing the
push button start while depressing
the clutch pedal (manual
transmission) or the brake pedal
(automatic transmission). To switch
the ignition position, press the push
button start without depressing the
pedal.
xDo not leave the ignition switched
ON while the engine is not running.
Doing so could result in the battery
going dead. If the ignition is left in
ACC (For automatic transmission,
the selector lever is in the P position,
and the ignition is in ACC), the
ignition switches off automatically
after about 25 minutes.
Off
The power supply to electrical devices
turns off and the indicator light
(amber) also turns off.
In this position the steering wheel is
locked.
WARNING
Before leaving the driver's seat,
always switch the ignition off, set the
parking brake, and make sure the
selector lever is in P (automatic
transmission) position or in 1st gear
or R (manual transmission):
Leaving the driver's seat without
switching the ignition off, setting the
parking brake, and shifting the selector
lever to P (automatic transmission)
position or to 1st gear or R (manual
transmission) is dangerous.
Unexpected vehicle movement could
occur which could result in an
accident.
In addition, if your intention is to leave
the vehicle for even a short period, it is
important to switch the ignition
off, as
leaving it in another position will
disable some of the vehicle's security
systems and run the battery down.
NOTE
(Locked steering wheel)
If the push button start indicator light
(green) is
flashing , a message is
displayed on the multi-information,
and the beep sound is heard, this
indicates that the steering wheel is not
unlocked. To unlock the steering
wheel, press the push button start
while moving the steering wheel left

WARNING
Do not stop the engine while the
vehicle is moving:
Stopping the engine while the vehicle
is moving for any reason other than in
an emergency is dangerous. Stopping
the engine while the vehicle is moving
will result in reduced braking ability
due to the loss of power braking ,
which could cause an accident and
serious injury.
1. Stop the vehicle completely.
2.(Manual transmission)
Shift into neutral and set the
parking brake.
(Automatic transmission)
Shift the selector lever to the P
position and set the parking brake.

off the engine. The ignition position
is off.
CAUTION
¾When leaving the vehicle, make sure
the push button start is off.
¾(SKYACTIV-D 1.8)
If the engine is started and stopped
repeatedly before it warms up, the

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.

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the
engine coolant temperature is
extremely high. Drive slowly to reduce
engine load. If the engine coolant
temperature gauge needle is in the red
range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take
appropriate measures.
Refer to Overheating on page 7-44.
NOTE
xIf the engine or engine coolant
temperature is high or low, the
engine output may be restricted to
protect the engine.
xDuring normal driving , the engine
coolant temperature stabilizes at 100
°C (210 °F) or less, and the gauge
indicates a range lower than 100 °C
(210 °F).
▼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.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warning light illuminates
or the fuel level is very low, refuel as
soon as possible.
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.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-58.
NOTE
xAfter 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.
