Traction battery (Lithium-ion battery)
The traction battery has a limited service life.
The traction battery capacity (the ability to store energy) 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 (outside
temperature, etc.) and usage conditions, such as how the vehicle is driven
and how the 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 traction bat-
tery capacity reduces, vehicle performance does not significantly become
worse.
In order to reduce the possibility of the capacity reducing, follow the directions
listed on P. 190, “Capacity reduction of the traction battery”.
CAUTION
■
High voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt sys-
tem.
DC and AC high voltage systems are 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 (orange) or their connectors.
●
The EV system will become hot after starting as the system uses high volt-
age. 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 under the driver
seat. The service plug is used only
when the vehicle is serviced and is sub-
ject to high voltage.
