Conditions affecting operation
The smart entry & start system, wireless remote control and immobilizer sys-
tem use weak radio waves. In the following situations, the communication
between the electronic key and the vehicle may be affected, preventing the
smart entry & start system, wireless remote control and immobilizer system
from operating properly. (Ways of coping: P. 513)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
When other wireless key (that emit radio waves) is being used nearby
When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio
waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
If window tint with a metallic content or metallic objects are attached to
the rear window

If the smart entry & start system does not operate properly
Locking and unlocking the doors: Use the mechanical key. (P. 513)
Starting the hybrid system: P. 514
Electronic key battery depletion
The standard battery life is 1 to 2 years.
As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. (P. 424)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps
When the electronic key battery is fully depleted
P. 424
Customization
Settings (e.g. smart entry & start system) can be changed.

System maintenance
The vehicle has a maintenance-free type alarm system.
Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure
of the following:
Nobody is in the vehicle.
The windows is closed before the alarm is set.
No valuables or other personal items are left in the vehicle.
Triggering of the alarm
The alarm may be triggered in the following situations.
(Stopping the alarm deactivates the alarm system.)
The doors are unlocked using the
mechanical key.
A person inside the vehicle opens a
door, the back door or hood.
The 12-volt battery is recharged or
replaced when the vehicle is locked.

148 1-7. Theft deterrent system
PRIUS +_OM_OM47841E_(EE)
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

196 2-1. Driving procedures
PRIUS +_OM_OM47841E_(EE)
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. (P. 536)
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.

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 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.
Sounds and vibrations specific to a hybrid vehicle
P. 4 2
Electronic key battery depletion
P. 7 7
When the ambient temperature is low, such as during winter driving
conditions
The “READY” indicator may flash for a long time when the hybrid system is
starting. Driving will become possible once the “READY” indicator has illumi-
nated. Wait until the “READY” indicator has illuminated.

Notes for the entry function
P. 7 4
If the hybrid system does not start
The immobilizer system may not have been deactivated. (P. 138)

210 2-1. Driving procedures
PRIUS +_OM_OM47841E_(EE)
When the “POWER” switch indicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the “POWER”
switch with the shift position in P and the brake pedal depressed, contact
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately.
If the hybrid system is malfunctioning
P. 464
If the electronic key battery is depleted
P. 424
Operation of the “POWER” switch
When operating the “POWER” switch, one short, firm press is enough. If
the switch is pressed improperly, the hybrid system may not start or the
“POWER” switch mode may not change. It is not necessary to press and
hold the switch.
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 system.
Automatically P position selection function
