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.)

■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.

■Operation of the power switch
●If the switch is not pressed shortly and firmly, the power switch mode may
not change or the hybrid system may not start.
●If attempting to restart the hybrid system immediately after turning the power
switch off, the hybrid system may not start in some cases. After turning the
power switch off, please wait a few seconds before restarting the hybrid sys-
tem.
■Automatically P position selection function

■When the shift control system malfunctions
The power switch will not be able to be turned off. In such a case, the switch
can be turned off after applying the parking brake.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer immediately.
■Meter display
When the power switch is turned off, each display will turn off as follows.
●The shift position indicator will turn off after approximately 2 seconds.
●EV driving ratio and average fuel consumption after hybrid system started,
turn off after approximately 6 seconds.
●The odometer, clock, etc. will turn off after approximately 30 seconds.
(Each display will also turn off immediately if a door is locked before 30 sec-
onds has elapsed.)

WARNING
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or press
it briefly 3 times or more in succession. ( P. 435)
However, do not touch the power switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.
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 the smart entry & start system indicator light (green) is illuminated (vehi-
cles without multi-information display), or “POWER ON” is displayed on
the multi-information display (vehicles with multi-information display) the
hybrid system is not off. When exiting the vehicle, always check that the
power switch is off.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.
■ Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer immediately.

EV drive mode
Turns EV drive mode on/off
When EV drive mode is turned on,
the EV drive mode indicator will
come on. Pressing the switch
when in EV drive mode will return
the vehicle to normal driving (using
the gasoline engine and electric
motor [traction motor]).
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it
cannot be turned on, a buzzer will sound and a message will be shown on the
multi-information display.
●The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
●The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 0C (32F) for a
long period of time etc.
●The gasoline engine is warming up.
●The hybrid battery (traction battery) is low.
The remaining battery level indicated in the energy monitor display is low.
(P. 118, 134)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
●The windshield defogger is in use.
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) is used to drive the vehicle.
This mode allows you to drive in residential areas late at night,
or in indoor parking lots etc. without concern for noises and
exhaust gas emissions.

2324-2. Driving procedures
PRIUS +_OM_OM47D30E_(EE)
■ Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically after a short period of time in order to warm up.
In this case, you will become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illumi-
nated, press the EV drive mode switch before the gasoline engine starts to
switch to EV drive mode.
■ Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart
in the following situations. When EV drive mode is canceled, a buzzer will
sound and the EV drive mode indicator will flash and go off.
● The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the energy monitor display is low.
( P. 118, 134)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a
prior notice screen will appear on the multi-information display.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 1 km (0.6 mile). However, depending on vehicle conditions,
there are situations when EV drive mode cannot be used. (The distance that
is possible depends on the hybrid battery [traction battery] level and driving
conditions.)
■ Changing a driving mode when in EV drive mode
EV drive mode can be used in conjunction with Eco drive mode and power
mode.
However, EV drive mode may be automatically canceled when used in con-
junction with power mode.
■ Fuel economy
The hybrid system is designed to achieve the best possible fuel economy
during normal driving (using the gasol ine engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
WARNING
■ Caution while driving
When driving in EV drive mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehi-
cle starting off or approaching them, so take extra care while driving.
