WARNING
●If a fire occurs in the Hybrid
Electric Vehicle, leave the vehi-
cle 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 four wheels
raised. If the wheels connected
to the electric motor (traction
motor) are on the ground when
towing, the motor may continue
to generate electricity. This may
cause a fire. (P.460)
●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.
■Hybrid battery (traction bat-
tery)
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly col-
lected, the follo wing may occur,
resulting in dea th or serious
injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment or someone may touch
a high voltage part, resulting in
an electric shock.
• The hybrid battery is intended to be used exclusively with your
Hybrid Electric Vehicle. If the
hybrid battery is used outside of
your vehicle or modified in any
way, accidents such as electric
shock, heat generation, smoke
generation, an explosion and
electrolyte leakage may occur.
When reselling or handing over
your vehicle, the possibility of an
accident is extremely high
because the person receiving the
vehicle may not be aware of these
dangers.
●If your vehicle is disposed of
without the hybrid battery hav-
ing been removed, there is a
danger of serious electric shock
if high voltage parts, cables and
their connectors are touched. In
the event that your vehicle must
be disposed of, the hybrid bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
NOTICE
■Hybrid battery (traction bat-
tery)
Do not carry large amounts of
water such as water cooler bottles
in the vehicle. If water spills onto
the hybrid battery (traction bat-
tery), the battery may be dam-
aged. Have the vehicle inspected
