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 EV driving range decreases when the hybrid bat-
tery (traction battery) capacity reduces, vehicle performance does not
significantly become worse.
In order to reduce the possibility of the capacity reducing, follow the direc-
tions listed on P. 113, "Capacity reduction of the hybrid battery (traction bat-
tery)".
 Declaration of conformity
This model conforms to hydrogen emissions according to regulation
ECE100 (Battery electric vehicle safety).
