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.
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 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.
● 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 caution labels attached to the vehicle.
●Never try to open the service plug
access hole located on the left-hand
side of the second seat base. The ser-
vice plug is used only when the vehicle
is serviced and is subject to high volt-
age.

■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in P, apply the parking
brake, 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 it 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 pos-
sible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with the four wheels raised. If the
wheels with the electric motor (traction motor) are on the ground when
towing, the motor may continue to generate electricity. This may cause an
electricity leakage leading to a fire.(
P. 521)
■ Nickel-metal hydride battery
Your vehicle contains a sealed nickel- metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.
■ Emergency shut off system
●Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (
P. 35)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.
