What to do when
charging is not possible
▼ What to do when charging is not
possible
If trouble arises while charging such as
not being able to charge the high
voltage battery, refer to the following
table. If the problem cannot be solved
even after checking the following table,
there may be a problem with the
vehicle or charger. Contact an
Authorized Mazda Dealer.
Charging is not possible.

Cause
Action
The selector
lever is in a
position
other than P. Shift the selector lever to the P
position.
The high
voltage bat-
tery is al-
ready fully
charged. Charging is not performed when
the high voltage battery is al-
ready fully charged.
The high
voltage bat-
tery temper-
ature is ex-
tremely high
or low. Check the high voltage battery
temperature gauge in the instru-
ment cluster. If the high voltage
battery temperature gauge is in
the red or blue range, charging
may not be possible.
The
Lead-acid
battery is
depleted. If the instrument cluster does not
turn on even if the power switch
is switched ON, the Lead-acid
battery may be depleted. Charge
or replace the Lead-acid battery.
Normal charging is not possible.

Cause
Action
The outlet
has no pow-
er. Check if a ground-fault circuit in-
terrupter has operated or if a
power outage occurred. If the
power source has a timer func-
tion, electrical power may not be
supplied to the outlet until the
time set to supply power.
The charge
plug is not
properly
plugged into
the outlet. Check if the charge plug is prop-
erly plugged into the outlet.
The charge
connector is
not properly
connected. Check if the charge connector is
properly connected.
Charging
timer is set. Cancel the charging timer using
EV Settings in Mazda Connect,
or the charging timer cancella-
tion function.
Troubleshooting for functions using a
Smartphone or computer

Jump-Starting
▼Jump-Starting
The lead-acid battery might be depleted
if the following conditions occur.
The EV system does not start.The selector lever cannot be shifted to a position other than P.The horn sound is weak or it does not sound.The brightness of the lights is extremely low.
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If
you feel unsure about jump-starting, we strongly recommend that you have a
competent service technician do the work.
Using commercially available booster cables, connect the lead-acid battery of the
booster vehicle’s battery to the lead-acid battery of your vehicle and start the EV
system.
WARNING
Follow These Precautions Carefully:
To ensure safe and correct handling of the lead-acid battery, read the following
precautions carefully before using the lead-acid battery or inspecting it.
Keep flames and sparks away from open lead-acid battery cells and do not
allow metal tools to contact the positive (+) or negative (–) terminal of the
lead-acid battery when working near a lead-acid battery. Do not allow the
positive (+) terminal to contact the vehicle body:
Flames and sparks near open lead-acid battery cells are dangerous. Hydrogen gas,
produced during normal lead-acid battery operation, could ignite and cause the
lead-acid battery to explode. An exploding lead-acid battery can cause serious burns
and injuries. Keep all flames including cigarettes and sparks away from open
lead-acid battery cells.

Keep all flames and sparks away from open
lead-acid battery cells because
hydrogen gas is produced from open le ad-acid battery cells while charging the
lead-acid battery or adding lead-acid battery fluid:
Flames and sparks near open lead-acid ba ttery cells are dangerous. Hydrogen gas,
produced during normal lead-acid battery operation, could ignite and cause the
lead-acid battery to explode. An explodin g lead-acid battery can cause serious burns
and injuries. Keep all fl ames including cigarettes and sparks away from open
lead-acid battery cells.
Do not jump-start a frozen lead-acid battery or one with a low fluid level:
Jump-starting a frozen lead-acid battery or one with a low fluid level is dangerous. It
may rupture or explode, causing serious injury.
Connect the negative cable to a good ground point away from the lead-acid
battery:
Connecting the end of the second jumper ca ble to the negative (–) terminal of the
depleted lead-acid battery is dangerous.
A spark could cause the gas around the lead-acid battery to explode and injure
someone.
Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving part (cooling fans) is dangerous. The
cable could get caught when the EV system starts and cause serious injury.
CAUTION
 Connect the booster cables with extreme care.
 Do not jump-start the vehicle with the charging cable connected to your vehicle.
Otherwise, the vehicle could be damaged.
 Do not use your vehicle as a booster vehicle.
NOTE
If your lead-acid battery is depleted, make sure that the booster vehicle's battery is
a lead-acid battery.
1. Move the booster vehicle so that its lead-acid battery is as close as possible to your vehicle's lead-acid battery.
2. Make sure that the power switch is switched OFF.

3. Remove the lead-acid battery cover.
4. Turn off the booster vehicle's engine and connect the jumper cables in the
following order.
Make sure that the jumper cables are se curely connected so that they do not
disconnect due to the vibrations.

CAUTION
In addition, the
eff ectiveness of the
braking may diminish so you may
need to depress the brake pedal
more strongly than normal to stop
the vehicle.
 When starting the EV system, the
brake system warning light may turn
on and the warning indication may
be displayed. In this case, park the
vehicle in a safe location and release
the brake pedal.

warning indication does not turn o ff
even after parking the vehicle, have
the vehicle inspected by an
Authorized Mazda Dealer.

▼ Electronic Brake Force Distribution
System Warning
If the electronic brake force
distribution control unit determines
that some components are operating
incorrectly, the control unit may
illuminate the brake system warning
light and the ABS warning light
simultaneously. The problem is likely to
be the electronic brake force
distribution system.
WARNING
Do not drive with both the brake
system warning light and ABS warning
light illuminated. Have the vehicle
towed to an Authorized Mazda
Dealer to have the brakes inspected as
soon as possible:
Driving when the brake system warning
light and ABS warning light are
illuminated simultaneously is
dangerous.
When both lights are illuminated, the
rear wheels could lock more quickly in
an emergency stop than under normal
circumstances.
