Electric Vehicle system
A value for which a sufficient level
of driving performance can be pro-
vided is estimated based on the
remaining charge of the traction
battery, the state of the traction bat-
tery, the outside temperature, etc.,
and is displayed on the multi-infor-
mation display. ( P.172)
When the outside temperature is
low, the traction battery output may
be decreased, causing the possible
driving distance to be shorter. How-
ever, this is not a malfunction.
Charge the traction battery earlier
than usual.
Possible driving distance varies sig-
nificantly depending on how the
vehicle is driven, road conditions,
the weather, the outside tempera-
ture, usage conditions of electrical
components and the number of
occupants.
Possible driving distance could be
extended if the followings are per-
formed:
 Maintain a safe distance from the
vehicle in front and avoid unnec-
essary acceleration and deceler-
ation
 Accelerate and decelerate the
vehicle as smoothly as possible
 Drive at moderate speeds as
much as possible and maintain a
constant speed
 Set the air conditioning system to
a moderate temperature and
avoid using the heating and cool-
ing functions excessively.
 Use tires of the specified size
and maintain the specified tire
pressure
 Do not add unnecessary weight
to the vehicle
The followings indicate that
charging has been carried out prop-
erly.
 The charging indicator turns off
 “Charging complete” is displayed
on the multi-information display
when a door is opened while the
power switch is off. ( P.117)
Regardless of the type of power
source or whether the charging
schedule function is used, charging
is completed if the above can be

days and the traction battery heater
automatically stops. It automatically
insulates the traction battery in
extremely low temperatures.
 This control stops 31 days after
the charging cable is connected,
even if it is still connected to the
vehicle.
 When this control operates,
charging schedule settings are
ignored and charging starts
immediately.
■Traction battery cooler
When the traction battery is hot and
the AC charging cable is connected
to the vehicle, this function cools
the traction battery to protect it.
The function may operate when
continuously driving at high speeds
such as driving on highways or
freeways, or during DC charging.
■Using My Room Mode during DC charging
 P. 1 4 6
■Traction battery heater
●Traction battery heater may operate when charging is not being performed.
●When Traction battery heater is oper-ating, the charging indicator will illumi-
nate.
●When Traction battery heater is oper-
ating during charging, the charging may take longer than normal.
●The remaining charge of the traction battery declines when the traction bat-tery heater operates, it might be nec-
essary to recharge the traction battery again in order to supplement the remaining charge.
■Traction battery cooler
●For AC charging: Traction battery cooler settings can be changed on the
multi-information display. ( P.115)
●The charging indicator will illuminate
when the traction battery cooler is on standby or operating.
●When the charge level of the traction battery is low, the traction battery cooler may not operate, even if the
temperature of the traction battery is high.
●When the following conditions are met while the traction battery cooler is operating, the cooling operation will
stop. • The hood is opened• The power switch is turned to ACC or
ON. • The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( P.427) • The remaining charge of the traction
battery drops below a certain amount
●The traction battery cooler operates
using power supplied by the traction battery and an external power source.• While the traction battery cooler is
operating, the charge of the traction battery will increase and decrease within a certain range, and will not
increase as during AC charging. • When the traction battery cooler oper-ates, charger will recognize it as the
battery being charged. If this function operates while a charger which charges a charging fee is connected
to the vehicle, AC charging fees will apply.
■Changing of the traction battery cooler setting
Setting can be changed on the
multi-information display.
Use the meter control switches
( P.176) and select “Vehicle Settings”, “Charging Settings”, “Battery Cooler”, and change the setting.

2-2. Charging
Electric Vehicle system
Before charging, always check the
following items.
 The parking brake is applied.
( P.254)
 The power switch is turned to
OFF. ( P.243)
 Lights such as the headlights,
emergency flashers and interior
lights, etc., are turned off.
If these light switches are turned on,
then these features will consume elec-
tricity, and charging time will increase.
Before charging, make sure that
each part of the AC charging cable
is in good condition. ( P.106)
■During charging
●The charging starting time may differ
depending on the state of the vehicle, but this does not indicate a malfunc-
tion.
●During charging, sounds may be
heard from near the traction battery in accordance with the operation of the air conditioning system or “Battery
Cooler” ( P.115).
●During and after charging, the motor
compartment and its surrounding area in which the onboard traction battery charger is installed may get warm.
●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.
■When charging using a public charging facility
●When charging using a public charging facility, check the setting of the charging schedule function.
• When the charging schedule is regis- tered, temporarily turn off the function or turn “Charge Now” on. ( P.134)
• When the charging schedule is set to on, charging will not start even if the AC charging cable is connected. Also,
charging fee may occur due to con- nection of the AC charging cable.
■Capacity reduction of the traction battery
The capacity of the traction battery will decline gradually when the traction bat-tery 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. Observing the
following can help suppress the decline in the traction battery capacity.
●Avoid parking the vehicle in high tem-perature areas, under direct sunlight when the traction battery is fully
charged.
●Avoid accelerating and decelerating
frequently and suddenly.
●Avoid frequent driving at high speed.
●Use the charging schedule function as much as possible in order to fully
charged the traction battery before starting off. ( P.134)
●Avoid frequent DC charging
Also, if the capacity of the traction bat-
tery capacity reduces, the distance that
can be driven decreases. However,
vehicle performance does not signifi-
cantly become worse.
