High voltage components
Take care when handling the hybrid system, as it contains a high volt-
age system (about 650V at maximu m) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle. Air conditioning compressor

■Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system bloc ks off the high voltage current
and stops the fuel pump to minimize the risk of electrocution and fuel
leakage when a certain level of impa ct is detected by the impact sen-
sor. If the emergency shut off syste m activates, your vehicle will not
restart. To restart the hybrid sy stem, contact your Toyota dealer.
Energy monitor/consumption screen
You can view the status of your
hybrid system on the multi-infor-
mation display (→P. 145) and the
navigation system screen*
( → P. 27, 29).
The following images are exam-
ples only, and may vary slightly

Hybrid warning messageA message is automatically displa yed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( →P. 357)
■If a warning light comes on or a wa rning message is displayed, or the
12-volt battery has been 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 your Toyota dealer.
■ When refueling, the fuel filler door may take a few moments to open
As part of emission system operation, it may take up to 10 seconds for the
fuel filler door to automatically release after the opener switch is pressed.
Before refueling is possible, a message will be shown on the multi-informa-
tion display. ( →P. 78)
■ 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. 351) 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 2.5 gal. [9.8 L,
2.1 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

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 and 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.
●Never try to open the service plug
access hole located in the luggage
compartment. The service plug is used
only when the vehicle is serviced and is
subject to high voltage.

CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in P, apply the parking
brake, 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 it 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 pos-
sible, 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 the front wheels raised. If the
wheels with 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. 342)
■ 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.
■ If the system activates
●Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (
→P. 25)
● 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.
