hybrid battery (traction battery) can change in accordance with driving style and
driving conditions.
CAUTION
■High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12 volt system. 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 and
their connectors.

Be careful of both the high voltage and the high temperature, and always obey
the caution labels attached to the vehicle.
●Never try to open the service plug access hole located in the luggage compart-
ment. The service plug is used only when the vehicle is serviced and is subject to
high voltage.
■Nickel-metal hydride battery

erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.
