Driving
Power (ignition) switch
Check that the parking brake is set.
Firmly depress the brake pedal.
and a message will be dis-
played on the multi-information dis-
play.
When the shift position is N, the
hybrid system cannot start. Shift
the shift position to P when starting
the hybrid system. ( P. 2 5 1 )
Press the power switch shortly
and firmly.
When operating the power switch,
one short, firm press is enough. It
is not necessary to press and hold
the switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake pedal until the “READY” indicator is illumi-
nated.
The hybrid system can be started from any power switch mode.
Check that the “R EADY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a sol id light and
the buzzer sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if t he engine
is stopped. (The gasoline engine starts or stops automatically in accor-
dance with the state of the vehicle.)
Performing the following opera tions when carrying the elec-
tronic key on your person starts the hybrid system or changes
power switch modes.

main display.
ON mode
All electrical components can be
used.
“Ignition ON” is displayed on the
main display.
■ Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minut es or ON
mode (the hybrid system is not operating) for more than an hour with the shift
position in P, the power switch will automatically turn off. Ho wever, this func-
tion cannot entirely prevent the 12-volt battery discharge. Do not leave the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.

NOTICE
■To prevent 12-volt battery discharge
● Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
● If “Accessory”, “Ignition ON” or mileage display (P. 117) is displayed on

Driving
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly t o remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a p ossible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically click s off.
● Do not top off the fuel tank.

Maintenance and care
Tire inflation
pressure
( P. 632)• Tire pressure gauge
• Compressed air source
Washer fluid
( P. 620)• Water or washer fluid containing antifreeze (for win-
ter use)
• Funnel (used only for adding water or washer fluid)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■ When working on the engine compartment
● Make sure that the “Accessory”, “Ignition ON” or mileage display
(P. 116) on the main display and the “READY” indicator are both off.
● Keep hands, clothing and tools away from the moving fan.
● Be careful not to touch the engine, power control unit, radiato r, exhaust
manifold, etc. right after driving as they may be hot. Oil and other fluids
may also be hot.
● Do not leave anything that may burn easily, such as paper and r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel. Fuel fumes
are flammable.
■ When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 614)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.

When trouble arises
After stopping the hybrid system and waiting for 5 minutes or
more, start the hybrid system again and check if “Hybrid System
Overheated” is shown on the multi-information display.
If the message d oes not disappear:
Stop the hybrid system and contact your Toyota dealer.
If the message is not displayed:
The hybrid system temperature has dropped and the vehicle may
be driven normally.
However, if the message appears again frequently, contact your Toyota
dealer.
WARNING
■ To prevent an accident or injury when inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
● If steam is seen coming from under the hood, do not open the ho od until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “Ac cessory”,
“Ignition ON” or mileage display ( P. 116) on the main display and the
“READY” indicator are off.
When the hybrid system is operating, the gasoline engine may au tomati-
cally start, or the cooling fans may suddenly operate even if the gasoline
engine stops. Do not touch or approach rotating parts such as the fan,
which may lead to fingers or clothing (especially a tie, a scarf or a muffler)
getting caught, resulting in serious injury.
● Do not loosen the coolant reservoir caps while the hybrid syste m and radi-
ator are hot.
High temperature steam or coolant could spray out.
