Fuel
CAUTION
 The e-SKYACTIV PHEV can be driven on electricity, but depending on the driving
conditions and mode, the vehicle will be driven using the engine and will need to
be refueled. Check the remaining amount of fuel and replenish the fuel if
necessary.
Refer to How to Use the Mazda intelligent Drive Select (Mi-Drive) on page 5-96.
 Depending on the vehicle usage conditions, fuel may remain in the tank for a long
period of time and the quality of the fuel may change. Refuel at least 25 L of fuel
every 12 months (total amount of refueling for 12 months is at least 25 L), as this
may affect parts of the fuel system and the engine.
 If the fuel has not been replenished for a certain period of time and the quality of
the fuel in the fuel tank is expected to change, a message is displayed in the

How to Use the
e-SKYACTIV PHEV
Switching the Drive Mode
You can switch the drive mode of the
hybrid system by operating the switch.
TOWING mode/SPORT mode/
NORMAL mode/EV mode/
OFF-ROAD mode
Refer to How to Use the Mazda
intelligent Drive Select (Mi-Drive) on
page 5-96.
CHARGE Mode
The engine is used as a generator, and
the vehicle is driven while charging the
high voltage battery.
1. Start the hybrid system.
2.
When CHARGE mode is activated, the
CHARGE mode indicator light
in
the instrument cluster turns on.
Power is generated to the preset target
charge amount, and when the target
charge amount is reached, power is
generated to maintain it.
NOTE
Switching to CHARGE mode may not
be possible depending on the
conditions of the hybrid system.
When power consumption is high
due to the vehicle driving conditions,
outside air temperature, or when the
air conditioner is used, charging may
take longer than usual or may not
occur.
When the vehicle is driven while in
CHARGE mode, the engine operates
to generate electricity, therefore fuel
consumption may increase
compared to when driving the
vehicle in a mode other than
CHARGE mode.
If the vehicle power is switched OFF
while switching the mode to
CHARGE mode, the CHARGE mode
will be canceled the next time the
vehicle power is switched ON.
When pressing the charge mode
switch while the Mazda intelligent
Drive Select (Mi-Drive) is in EV
mode, the Mi-Drive switches to
NORMAL mode and the vehicle is
driven in CHARGE mode.
The mode may not be able to switch
to CHARGE mode when the fuel is
low.
The target charge amount can be
changed.
Refer to the Settings section in the
Mazda Connect Owner's Manual.

Convenient Ways to Usethe e-SKYACTIV PHEV
Switch to Start in EV Mode
The hybrid system can be changed to
start in EV mode.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
Switching the Regenerative Braking
Strength
The regenerative braking strength can

For Eco-Friendly and Economical
Driving
Using the Drive Mode
EV mode is mainly used in urban areas,
while NORMAL mode is used in
suburban areas and on expressways,
which leads to savings in electricity and
fuel consumption.
By actively using regenerative braking
to charge the high voltage battery, it is
possible to increase the EV travel
distance and to reduce fuel
consumption when driving the vehicle
in a mode other than EV mode.
To extend cruising distance
The electrical power consumption
while driving can be reduced and the
cruising distance can be extended by
doing the following operations.
With the charge connector
connected, turn on the climate
control system to provide a
comfortable temperature in the
cabin before driving.
When driving during cold
temperatures, use the seat warmer or
steering warmer instead of the
climate control system.
Adjust the climate control system to
a moderate airflow and temperature
setting.
Refrain from using the defogger
under conditions other than when a
window is fogged or frozen.
By maintaining a sufficient distance
between vehicles and using the
regenerative braking well, more
electrical power can be charged to
the high voltage battery.
To extend the life of the high voltage
battery
The high voltage battery life changes
depending on the vehicle storage
conditions or charging method.
To extend the life of the high voltage
battery, be careful of the following.
(Charging the battery)
Avoid unnecessary, frequent
charging.
Only charge the battery with as much
power as needed, and do not always
fully charge the battery. The
maximum charge limit can be set.
Refer to Convenient Ways to Use of
Charging on page 5-118.
(Parking the vehicle)
Do not park the vehicle in a place
where the ambient temperature is
extremely high or low.
Do not leave the vehicle while the
remaining high voltage battery power
is extremely low.
If the [Battery Cooling] operation notification is displayed on the
center display after driving the
vehicle, select [Activate].

Remaining Charge and Temperature
of the High Voltage Battery
If the high voltage battery level is low
or the high voltage battery temperature
is low, the vehicle speed may not
increase even if the accelerator pedal is
depressed because the motor output is
restricted. Check the contents
displayed in the instrument cluster and
the remaining amount of power in the
high voltage battery before driving.
(Battery cooling)
If the high voltage battery temperature
is high after driving the vehicle, it is
possible to cool the high voltage
battery while the vehicle is parked to
extend the life of the high voltage
battery. If the Excessive Battery
Te m p e ra t u r e notification is displayed
on the center display after driving the
vehicle, select Start to start the battery
cooling.
NOTE
Because the electrical power of the
