■
To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If the hybrid system is off, but the indicator on the “POWER” switch is illu-
minated, this indicates that the “POWER” switch is still turned on. When
exiting the vehicle, always check that the “POWER” switch is off.

EV drive mode
In EV drive mode, the electric motor (traction motor), powered by the
hybrid battery (traction battery), 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.
Turns EV drive mode on/off
When EV drive mode is turned
on, the EV drive mode indica-
tor will come on.
Pressing the switch when in
EV drive mode will return the
vehicle to normal driving (using
the gasoline engine and elec-
tric 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 to inform the driver.
●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 32
F (0C)
for a long period of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
When the amount of remaining hybrid battery (traction battery) charge
displayed on the meter is low. ( P. 197)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
*: Depending on the circumstances, EV drive mode may also not be
switched to in situations other than those above.
■ Switching to EV drive mode wh en 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.
● Vehicle speed becomes high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about 1.3 mile (2 km) \
if driving
at a speed of about 25 mph (40 km/h) or less. (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
PRIUS v is designed to achieve the best possible fuel economy during nor-
mal driving (using the gasoline engine and electric motor [traction motor]).
Driving in EV drive mode more than necessary may lower fuel economy.
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 vehicle
starting off or approaching them, so take extra care while driving.
