NOTICE
■
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.
■ Symptoms indicating a malfun ction 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. Con-
tact your Toyota dealer immediately.

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 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 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. 44)
● 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 is designed to achieve the bes t possible fuel economy during normal
driving (using the gasoline engine and electric motor [traction motor]). Driv-
ing 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.

When driving
Hybrid transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Shift lever
Operate the shift lever gently and ensure correct shifting operation.
Release the shift lever after each shifting operation to allow it to return
to the position.
When shifting to the D or R positions, move the shift lever
along the shift gate.
To shift to the N position, slide the shift lever to the left and hold
it. The shift position will change to N.
To shift to the B position, pull the shift lever down. Shifting to B
is only possible when shift position D is selected.
When shifting from P to N, D or R, from D to R, or from R to D, ensure
that the brake pedal is being depressed and the vehicle is stationary.

206 2-1. Driving procedures

Shift position indicator
The position of the frame on the shift position indicator changes in
accordance with the current shift position.
When any shift position other than D or B is selected, the arrow toward
B and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position indica-
tor provided on the instrument cluster.
■ Shift position purpose
*: For good fuel economy and noise reduction, the D position should usu-
ally be used.

Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator pedal depression amount can be
generated more smoothly than it is in normal conditions and the
operation of the air conditioning system (heating/cooling) will be
minimized.
When the “ECO MODE” switch is pressed, the “ECO MODE” indicator
comes on.
Power mode
Use when high levels of response and feeling are desirable,
such as when driving in mountainous regions or when overtak-
ing.
When the power mode switch is pressed, the power mode indicator
comes on.

P position switch■ When shifting the shift position to P
Fully stop the vehicle and set the
parking brake, and then press
the P position switch.
When the shift position is
changed to P, the indicator comes
on.
Check that the P position is illumi-
nated on the shift position indica-
tor.
■Shifting the shift position from P to other positions
●While depressing the brake pedal firmly, operate the shift lever.
If the shift lever is operated wi thout depressing the brake pedal,
the buzzer will sound and the shif ting operation will be disabled.
● When selecting the shift position, make sure that the shift posi-
tion has been changed to the desired position by checking the
shift position indicator provi ded on the instrument cluster.
● The shift position cannot be changed from P to B directly.
