■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.
■ Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100
(Battery electric vehicle safety).
WARNING
■ High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem. DC and AC high voltage is very dangerous and can cause severe
burns and electric shock that may result in death or serious injury.
● Never touch, disassemble, remove or replace the high voltage parts,
cables or their connectors.
● The hybrid system will become hot after starting as the system uses high
voltage. Be careful of both the high voltage and the high temperature, and
always obey the warning labels attached to the vehicle.
■ Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● Never try to open the service plug
access hole located underneath the
rear seats. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.
