After the 12-volt battery has discharged or has been changed or
removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
Motor sounds may be heard from the engine compartment.
Sounds may be heard from the hybrid battery (traction battery) under the
rear seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the back door is
open.
Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal
is depressed and accelerator is loosened.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vent on the side of
the lower part of the rear left seats.
Maintenance, repair, recycling, and disposal
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.

Hybrid system precautions
Take care when handling the hybrid system, as it contains a high
voltage system (about 520 V at maximum) as well as parts that
become extremely hot when the hybrid system is operating. Obey
the caution labels attached to the vehicle.

Hybrid battery air vent
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cool-
ing the hybrid battery (traction
battery). If the vent becomes
blocked, the hybrid battery (trac-
tion battery) may overheat, lead-
ing to a reduction in hybrid
battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle will
not restart. To restart the hybrid system, contact any authorized Toy-
ota dealer or repairer, or another duly qualified and equipped profes-
sional.
If a warning light comes on, or the 12-volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light (P. 566) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 7.0 L [1.8 gal.,
1.5 lmp. gal.] when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

Electromagnetic waves
High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline powered vehicles or
home electronic appliances.
Your vehicle may cause sound interference in some third party-produced
radio parts.
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.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation
ECE100 (Battery electric vehicle safety).
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 or 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.
The service plug is installed in the
hybrid battery (traction battery). The
service plug is used only when the vehi-
cle is serviced and is subject to high
voltage.
Never touch the service plug, as a mis-
take in handling can lead to an electric
shock.

CAUTION
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
Stop the vehicle in a safe place to prevent subsequent accidents, shift the
shift lever to P, apply the parking brake, and turn the hybrid system off.
(P. 237, 242)
Do not touch the high voltage parts, cables or 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 the fluid 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 possible, 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 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. This may
cause an electricity leakage leading to a fire. (P. 549)
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 and contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.
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.

NOTICE
Hybrid battery air vent
Do not put foreign objects over or in
front of the air vent. The hybrid battery
(traction battery) may overheat and be
damaged.
Clean the air vent regularly to prevent
the hybrid battery (traction battery) from
overheating.
Do not wet or allow foreign substances
to enter the air vent as this may cause a
short circuit and damage the hybrid bat-
tery (traction battery).
Do not carry large amounts of water
such as water cooler bottles in the vehi-
cle. If water spills onto the hybrid bat-
tery (traction battery), the battery may
be damaged.
