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. 235)
Press the power switch.
If the “READY” indicator turns on,
the hybrid system will operate nor-
mally.
Continue depressing the brake
pedal until the “READY” indicator
is illuminated.
The hybrid system can be started
from any power switch mode.
Check that the “READY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a solid 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 the engine
is stopped. (The gasoline engine starts or stops automatically in accor-
dance with the state of the vehicle.)
Performing the following operati ons when carrying the elec-
tronic key on your person starts the hybrid system or changes

■ Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes 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. However, 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.

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 to 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 possible 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 clicks off.
● Do not top off the fuel tank.

7208-2. Steps to take in an emergency
PRIUS_OM_OM47A29U_(U)
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 does 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 hood until
the steam has subsided. The engine compartment may be very hot.
● After the hybrid system has been turned off, check that the “Accessory”,
“Ignition ON” or mileage display ( P. 108) on the multi-information display
and the “READY” indicator are off.
When the hybrid system is operating, the gasoline engine may automati-
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 system and radi-
ator are hot.
High temperature steam or coolant could spray out.
