2864-2. Opening, closing and locking the doors
Prius Plug-in Hybrid_OM_OM47E75E_(EE)QConditions 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. 693)
OWhen the electronic key battery is depleted
ONear a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
OWhen 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
OWhen other wireless key (that emit radio waves) is being used nearby
OWhen carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wireless commu-
nication devices
• 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
OIf window tint with a metallic content or metallic objects are attached to the
rear window
OWhen the electronic key is placed near a battery charger or electronic
devices

Operation of each component
QNote for the entry function
OEven when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, floor, or in the door pockets
or glove box when the hybrid system is started or power switch modes
are changed.
ODo not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
OAs long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.
OEven if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
OThe doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
30 seconds if the doors are not opened and closed.)
OIf the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
OTouching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
OOn some models: When the lock operation is performed using the lock sen-
sor, recognition signals will be shown up to two consecutive times. After this,
no recognition signals will be given.
OIf the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set electronic key to battery-saving mode to disable the smart entry &
start system. (P. 285)

WARNING
QCaution regarding interference with electronic devices
O People with implantable cardiac pacemakers, cardiac resynchronization
therapy-pacemakers or implantable cardioverter defibrillators s hould keep
away from the smart entry & start system antennas. ( P. 283)
The radio waves may affect the operation of such devices. If ne cessary,
the entry function can be disabled. Ask any authorized Toyota r etailer or
Toyota authorized repairer, or any reliable repairer for detail s, such as the
frequency of radio waves and timing of the emitted radio waves. Then,
consult your doctor to see if you should disable the entry func tion.
O Users of any electrical medical device other than implantable cardiac
pacemakers, cardiac resynchroni zation therapy-pacemakers or implanta-
ble cardioverter defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves.
Radio waves could have unexpected effects on the operation of s uch
medical devices.
Ask any authorized Toyota retailer or Toyota authorized repaire r, or any reli-
able repairer for details on disabling the entry function.

3765-5. Using the driving support systems
Prius Plug-in Hybrid_OM_OM47E75E_(EE)• When using an automatic car wash
• When driving through steam or smoke
• When driving near an object that reflects radio waves, such as a large
truck or guardrail
• When driving near a TV tower, broadcasting station, electric power plant,
or other location where strong radio waves or electrical noise may be
present
QSituations in which the system may not operate properly
OIn some situations such as the following, an object may not be detected by
the radar sensor and front camera, preventing the system from operating
properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden swerv-
ing, acceleration or deceleration)
• When your vehicle approaches a detectable object rapidly
• When a detectable object is near a wall, fence, guardrail, manhole cover,
vehicle, steel plate on the road, etc.
• When a detectable object is under a structure
• When part of a detectable object is hidden by an object, such as large
baggage, an umbrella, or guardrail
• When multiple detectable objects are close together
• If the sun or other light is shining directly on a detectable object
• When a detectable object is a shade of white and looks extremely bright
• When a detectable object appears to be nearly the same color or bright-
ness as its surroundings
• If a detectable object cuts or suddenly emerges in front of your vehicle
• When the front of your vehicle is hit by water, snow, dust, etc. • When driving through or under

QThe wireless charger can be operated when
The power switch is in ACCESSORY or ON mode.
QUsable portable devices
Qi standard wireless charge standard can be used on compatible devices.
However, not all Qi standard devices and compatibility are guaranteed.
Starting with mobile phones and smart phones, it is aimed for low power elec-
trically supplied portable devices of no more than 5W.
QWhen covers and accessories are attached to portable devices
Do not charge in situations where cover and accessories not able to handle
Qi are attached to the portable device. Depending on the type of cover and
accessory, it may not be possible to charge. When charging is not performed
even with the portable device placed on the charge area, remove the cover
and accessories.
QWhile charging, noise enters the AM radio
Turn off the wireless charger and confirm that the noise has decreased. If the
noise decreases, continuously pushing the power supply switch of the wire-
less charger for 2 seconds, the frequency of the charger can be changed and
the noise can be reduced.
Also, on that occasion, the operation indicator light will flash orange 2 times.
QImportant points of the wireless charger
OIf the electronic key cannot be detected within the vehicle interior, charging
cannot be done. When the door is opened and closed, charging may be
temporarily suspended.
OWhen charging, the wireless charging device and portable device will get
warmer, however this is not a malfunction.
When a portable device gets warm while charging, charging may stop due
to the protection function on the portable device side. In this case, when the
temperature of the portable device drops significantly, charge again.
QOperation sounds
When the power supply is turned on, while searching for the portable device a
sound will be produced, however this is not a malfunction.
