WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r 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.
● 2ZR-FXE engine (for Guadelope, Martinique, F. Guiana and Greenland): If
a fluid leak occurs, do not touch the fluid as it may be strong alkaline elec-
trolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large am ount of water
or, if possible, boric acid solution. Seek immediate medical at tention.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): Do not touch the batte ry if liquid is leaking from or adhering to
it. If electrolyte (carbonic-based organic electrolyte) from th e hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes i nto contact
with the eyes or skin, wash it of f immediately with a large amount of water,
and seek immediate medical attention.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): If electrolyte is leaking from the hybrid battery ( traction bat-
tery), do not approach the vehicle. Even in the unlikely event that the
hybrid battery (traction battery) is damaged, the internal cons truction of
the battery will prevent a large amount of electrolyte from lea king out.
However, any electrolyte that does leak out will give off a vap or. This vapor
is an irritant to skin and eyes and could cause acute poisoning if inhaled.
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): Do not bring burning or high-temperature items close to the
electrolyte. The electrolyte may ignite and cause a fire.
● If a fire occurs in the Hybrid Electric Vehicle, leave the vehicle as soon as
possible. Never use a fire extinguisher that is not meant for e lectric fires.
Using even a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front 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. Th is may
cause a fire. ( P. 674)
● 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.

WARNING
■Hybrid battery (traction battery)
● 2ZR-FXE engine (except for Guadelope, Martinique, F. Guiana and
Greenland): Your vehicle contains a sealed lithium-ion battery.
● Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through any authorized Toyota retailer or Toyota authori zed repairer,
or any reliable repairer. Do not dispose of the battery yoursel f.
Unless the battery is properly collected, the following may occ ur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage p art,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with you r Hybrid
Electric Vehicle. If the hybrid battery is used outside of your vehicle or
modified in any way, accidents such as electric shock, heat gen eration,
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 having been
removed, there is a danger of serious electric shock if high vo ltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by any autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer
or a qualified service shop. If the hybrid battery is not dispo sed of properly,
it may cause electric shock that can result in death or serious injury.

NOTICE
■Hybrid battery (traction battery) air intake vent
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust, etc., has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction b attery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction batt ery), the battery
may be damaged. Have the vehicle inspected by any authorized To yota
retailer or Toyota authorized repairer, or any reliable repaire r.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filte r cleaning or
replacement is recommended. For information regarding filter cl eaning or
replacement, refer to P. 640.
● If “Maintenance required for Traction battery cooling parts. See owner’s
manual.” is shown on the multi-information display, the air int ake vent and
filter may be clogged. Refer to P. 640 for information on how t o clean the
