Alarm-operated door lock
When the alarm is operating, the doors are locked automatically to pre-
vent intruders.
Do not leave the key inside the vehicle when the alarm is operating, and
make sure the key is not inside the vehicle when recharging or replacing
the 12-volt battery.
Canceling and automatic re-enabling of the intrusion sensor
The alarm will still be set even when the intrusion sensor is canceled.
After the intrusion sensor is canceled, pressing the “POWER” switch or
unlocking the doors using the entry function or wireless remote control
will re-enable the intrusion sensor.
When the alarm system is set again, the intrusion sensor will be set.
Intrusion sensor considerations
The sensor may trigger the alarm in the following situations:
Persons or pets are in the vehicle.
A window is open.
In this case, the sensor may detect the
following:
• Wind or the movement of objects
such as leaves and insects inside
the vehicle
• Ultrasonic waves emitted from
devices such as the intrusion sen-
sors of other vehicles
• The movement of people outside
the vehicle

Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 542)
For efficient use
Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift position in the N position for an extended period of time
may discharge the hybrid battery (traction battery). The vehicle cannot
run if the hybrid battery (traction battery) is discharged.
CAUTION
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. This prevents the vehicle from creeping.

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 function cannot entirely prevent the 12-volt battery from discharging. 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
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 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. Con-
tact any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional 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 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.

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.
