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
high voltage battery is used by the
battery cooling , we recommend that
the charge connector is connected
while the battery cooling is operating.

On roads with high driving resistance
such as deep-snowy or sandy roads,
or on steep slopes, a high load is
applied to the transmission, causing
excessive heat generation. Under
these driving conditions, pay
attention to the following points.
 Stop and hold the vehicle on a
steep slope with the brake pedal,
not the accelerator pedal. Do not
use the accelerator pedal to
prevent the vehicle from rolling.
 Avoid using the accelerator pedal
and the brake pedal at the same
time.
 Start driving the vehicle in the D or
R position according to the
direction of travel (avoid starting in
manual mode).
If you do not follow the above
precautions, the transmission may
overheat. If a message, such as
transmission cooling, is displayed, it
is necessary to temporarily stop the
vehicle to cool the transmission.How to Use the Selector Lever

How to Use the Tire
Pressure Monitoring System (TPMS)
Check the tire pressure
The current tire pressure can be
checked on the center display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
Low tire pressure warning
When a tire pressure of the specified
air pressure or lower is detected, the
TPMS warning light
turns on and a
warning indication is displayed in the
instrument cluster.
1. Message is displayed.
Action
1. Adjust the tire pressure to the appropriate pressure.
Refer to the Tires on page 10-71.
CAUTION
If the tire pressure is adjusted when
the tire is warm, the tire pressure
may lower below the specified
pressure after cooling and the
warning light may turn on. Adjust
the air pressure of the tires when
they are cold.
2. Make sure that the TPMS warning
light
is turned off.
3. If the TPMS warning light does
not turn off, drive the vehicle for 3
minutes or longer at a speed of 25
km/h (16 mph) or faster.
4. Make sure that the TPMS warning
light
is turned off.
If the TPMS warning light remains on
even after adjusting the tire pressure,
there is a possibility that the tire is flat.
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to register the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed
of 25 km/h (16 mph) or faster for 3
minutes or longer. While driving,
the ID signal codes of the tire
pressure sensors are automatically
registered.
