Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service life.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as \
how
the vehicle is driven and how the hybrid battery (traction battery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV mode
decreases when the hybrid battery (traction battery) capacity reduces, vehi-
cle performance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the direc-
tions listed on P. 97, “Capacity reduction of the hybrid battery (traction bat-
tery)”.

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 distance
that can be driven in EV mode decreases. However, vehicle performance
does not significantly become worse.
