WARNING
■High voltage 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 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 warning labels attached to the vehicle.
■ Road accident cautions
Observe the following precautions to reduce the risk of death or 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.
● 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.
● Never try to open the service plug
access hole located underneath the
rear seats. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.

WARNING
●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 a fire. ( P. 509)
● 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 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 authorized repairer,
or any reliable repairer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, 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 part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your 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 having 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 battery must be disposed of by any autho-
rized Toyota retailer or Toyota author ized repairer, or any reliable repairer,
or a qualified service shop. If the hybrid battery is not disposed of properly,
it may cause electric shock that can result in death or serious injury.

NOTICE
■Hybrid battery (traction battery) air intake vent
● 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 battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. For information regarding filter cleaning or
replacement, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● Vehicles with color display: If “Maintenance required for Traction battery
cooling parts. See owner’s manual.” is shown on the multi-information dis-
play, the air intake vent and filter may be clogged. Refer to P. 420 for infor-
mation on how to clean the air intake vent.
● Do not place objects that will block the
air intake vent. When the air intake vent
is blocked, the battery operations will be
restricted and cause a decline in fuel
consumption.
● Clean the air intake vent regularly to
prevent the hybrid battery (traction bat-
tery) from overheating.

*1: These lights turn on when the power switch is turned to the “ON” position
(vehicles without a smart entry & start system) or ON mode (vehicles with
a smart entry & start system) to indicate that a system check is being per-
formed. They will turn off after the hybrid system on, or after a few sec-
onds. There may be a malfunction in a system if a light does not come on,
or if the lights do not turn off. Have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

● By keeping the indicator needle within Eco area, more Eco-friendly driving
can be achieved.
● Charge area indicates regeneration* status. Regenerated energy will be
used to charge the hybrid battery (traction battery).
*: When used in this manual, “regeneration” refers to the conversion of
energy created by the movement of the vehicle into electrical energy.
■ Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions, etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.
■ Outside temperature display
● In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 25 km/h [16 mph])
• When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
● When “- -” or “E” is displayed, the system may be malfunctioning.
Take your vehicle to any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
● The temperature range that can be displayed is from -40°C (-40°F) to 50°C
(122°F).
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or comes on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.
