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 0
C (32F)
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. 236)
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 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.
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 2 km (1.3 mile) if driving
at a speed of about 45 km/h (28 mph) 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 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.

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.
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 (left-
hand drive vehicles) or right (right-hand drive vehicles) and
hold it. The shift position will change to N.
Shifting to B is only possible when shift position D is selected.
The shift lever will always return to this original position after a
shifting operation.
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.

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.

226 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
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.

227 2-1. Driving procedures

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 switch 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 without depressing the brake pedal,
the buzzer will sound and the shifting 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 provided on the instrument cluster.
The shift position cannot be changed from P to B directly.

228 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. (P. 226) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
For the shift positions
When the “POWER” switch is off, the shift position cannot be changed.
When the “POWER” switch is in ON mode (the hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
When the “READY” indicator is flashing, the shift position cannot be
changed from P to other position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.
The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
Situations where the shifting operation will be disabled:
• When an attempt is made to change the shift position from P to other
position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B
by moving the shift lever.

Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.
*1
• When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.
*2
• When an attempt is made to select the D position by moving the shift
lever when the vehicle is moving in reverse.
*3
• When an attempt is made to change the shift position from R to B by
moving the shift lever.
*1: Shift position may be changed to P when driving at extremely low
speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
When the accelerator pedal is depressed while the shift position is in N
A buzzer will sound to inform the driver that the shift position is in N.
Automatically P position selection function
When the shift position is in a position other than P, pressing the “POWER”
switch with the vehicle stopped completely will cause the shift position to
change to P automatically, and then the “POWER” switch will turn off.
If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 522)

230 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, shift the shift position to D.
When canceling Eco drive mode/power mode
Press the switch again. Also, power mode will be canceled automatically
when the “POWER” switch is turned off. However, Eco drive mode will
not be canceled automatically until the switch is pressed, even if the
“POWER” switch is turned off.
When in Eco drive mode, if the power mode switch is pressed or the
operation is reversed, the mode will switch to that of the last switch to be
pressed.
