■Hybrid battery (traction battery) status
When driving in EV mode, the battery display will switch when the
remaining charge display reaches one fifth of the total, and HV
mode will be switched to when the level reaches 6 or below.
The display when switching from EV mode to HV mode is different to the
display when switching from HV mode to EV mode.
*1: Switching to HV mode using the EV/HV mode selection switch is possi-
ble.
*2: Switching to EV mode using the EV/HV mode selection switch is not pos-sible.
*3: Switching to EV mode using the EV/HV mode selection switch is possi-ble.

Remaining hybrid battery (traction battery) charge display
The remaining charge display of the hybrid battery (traction battery) icon on
the multi-information display switches in accordance with the remaining
charge. ( P. 60)
■ Resetting the consumption data
Display Audio system
Selecting “Clear” on the “Consumption” screen will reset the fuel consump-
tion and the regenerated energy for the past 30 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.
Navigation system
Selecting “Clear” on the “Consumption” screen will reset the fuel consump-
tion and the regenerated energy for the past 30 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.
Multi-information display
If the “POWER” switch is turned OFF, average fuel consumption and regen-
erated energy data will be reset.
■ EV driving range display
When in EV mode or when necessary charge is remaining for EV mode, the
EV driving range can also be confirmed using the Hybrid System Indicator\
.
(P. 268)
■ Resetting the monthly fuel consumption
Press and hold the “TRIP” button while the monthly fuel consumption is dis-
played.
A confirmation message will be displayed.
Press and hold the “TRIP” button to reset the data.
Press the “DISP” button to cancel the reset operation. The screen will return
to the previous display if no buttons are pressed for approximately 10 sec-
onds.

■Cruising range
Displays the estimated distance that can be driven with the quantities of fuel
and hybrid battery (traction battery) charge currently remaining.
This distance is computed based on your average fuel consumption.
As a result, the actual distance that can be driven may differ from that dis-
played.
■ Odometer/trip meter/distance to empty
The odometer/trip meter/distance to empty will not be displayed while the
monthly fuel consumption record is being displayed.

Charging timer functionBy using the charging timer function, deterioration of the hybrid bat-
tery (traction battery) charge can be suppressed ( P. 93), and off-
peak electricity can be used effectively.
● A charging time can be assigned by setting the charging start time
or finish time.
● Once the time has been set, the time can be assigned again next
time simply by pressing the charging timer switch.
Remove the plug from the out-
let when the charging equip-
ment will not be used for a
prolonged period of time.
Hold the body of the plug when
removing.
Make sure to put the cable
away immediately after discon-
necting. ( P. 95)
When leaving the plug
inserted, inspect the plug and
connector once a month to
check if dirt or dust has accu-
mulated.

■Charging messages
The first time the “POWER”
switch is turned to ON mode
after charging is completed, a
message detailing the results of
the charging will be displayed.
Also, if an operation which can-
not be carried out is attempted
during charging, a warning mes-
sage will be displayed.
( P. 562)
Comply with the instructions in
the message and carry out any
necessary operations.
The message may not be dis-
played if the Remote Air Condi-
tioning System ( P. 371) has
been used.
■ Amount of time until charging is complete
Charging fully from an EV driving range of 0 mile (0 km) ( P. 58) will take
approximately 2.5 hours (AC120 V).
The amount of time until charging is complete will change in accordance with
the amount of charge remaining in the hybrid battery (traction battery), the
outside temperature, etc.
■ During charging
● The surface of the CCID (Charging Circuit Interrupting Device) may
become hot, but this does not indicate a malfunction.
● Depending on radio wave conditions, interference may be heard on the
radio.

■Charging timer function (finish time setting mode)
● The finish time setting mode should only be used as a reference for the
time at which charging will finish.
Charging may not complete at the finish time depending on the effects of
the electricity supply, temperature etc. In this event, charging will continue
until completed.
● If the function detects that charging cannot be finished on time, charging
will start immediately, and will continue until fully charged.
■ Charging indicator
● The charging indicator illuminates if the Remote Air Conditioning System
(P. 371) is used during charging or while the charging cable is con-
nected.
● If a system malfunction occurs during charging or during Remote Air
Conditioning System use, the indicator will flash for approximately 10
seconds and then turn off.
■ When the outside temperature is low or high
The level shown on the remaining charge display ( P. 60) may drop slightly
when the “POWER” switch is turned to ON mode, even if charging has been
completed and the hybrid battery (traction battery) is fully charged. However,
this does not indicate a malfunction.
■ Using a DC Charger
DC Chargers cannot be used with this vehicle.

Charging time may increase
In the following situations, charging time may become longer than normal:
● In very hot or very cold temperatures.
● The vehicle is consuming a lot of electricity, for example, when the head-
lights or emergency flashers switch is on.
● There is a power outage during charging.
● There is an interruption in the electrical supply.
● There is a drop in the voltage of your panel’s AC supply.
● The charge in the 12-volt battery is low, for example due to the vehicle
being left unused for a long period of time.
■ Capacity reduction of the hybrid battery (traction battery)
The charge of the hybrid battery (traction battery) will decline gradually when
the hybrid battery (traction battery) is in use. The rate at which it declines will
differ in accordance with environmental conditions and the way in which the
vehicle is used. By observing the following precautions, battery charge
decline can be suppressed.
● Avoid parking the vehicle in areas with a high temperature under direct
sunlight when the hybrid battery (traction battery) is fully charged.
● Do not accelerate or decelerate frequently and suddenly when driving in
EV mode.
● Avoid frequent driving near the top speed for EV driving. ( P. 40)
● Leave a low level of charge in the hybrid battery (traction battery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the
“POWER” switch off.
● Use the charging timer function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting
off.
Also, if the hybrid battery (traction battery) capacity reduces, the EV driving
range decreases. However, vehicle performance does not significantly
become worse.
