WARNING
■ General precautions while driving
Driving under the influence: Never drive your vehicle when unde r the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judg ment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistake s that other
drivers or pedestrians might make and be ready to avoid acciden ts.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serio us injury to you,
your occupants or others.
■ General precaution regar ding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by p laying with
the cigarette lighter, the windows, the moon roof, or other fea tures of the
vehicle. In addition, heat build-up or extremely cold temperatu res inside the
vehicle can be fatal to children.

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

■If a warning light comes on, a warning message is displayed, or the 12-
volt battery has been disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dea ler.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at least enough gasoline to make the lo w fuel level
warning light ( P. 482) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
1.3 gal. [5.0 L, 1.1 Imp. gal.] when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate el ectromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-p roduced
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.

WARNING
■High voltage and high temperature precautions
This 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 sev ere
burns and electric shock that may result in death or serious in jury.
● Never touch, disassemble, remove or replace the high voltage pa rts,
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 tempe rature, and
always obey the warning labels attached to the vehicle.
● Never try to open the service plug
access hole located under the rear seat.
The service plug is used only when the
vehicle is serviced and is subject to high
voltage.

WARNING
■Hybrid battery (traction battery)
● Never resell, hand over or modify the hybrid battery. To preven t accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
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
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 havin g 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 your
Toyota dealer or a qualified service shop. If the hybrid battery is not dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.
