■ Conditions affecting operation
The smart entry & start system uses weak radio waves. In the fo llowing situa-
tions, the communication between the electronic key and the veh icle may be
affected, preventing the smart entry & start system, wireless r emote control
and immobilizer system from operating properly. (Ways of coping : P. 744)
● 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 wav es or electrical
noise
● When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
● 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 keys (that emit radio waves) are being used nearby
● When carrying the electronic key together with the following devices that
emit radio waves
• Portable radio, cellular phone, cordless phone or other wirele ss commu-
nication devices
• Another electronic key or a wireless key that emits radio wave s

Operation of each component
C-HR_HEV_OM_Europe_OM10764E
■ Note for the entry function
● Even 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 unl ocked.
• The electronic key is near the ground or in a high place, or t oo close to
the rear bumper center w hen the back door is opened.
• The electronic key is on the instrument panel, floor, or in th e door pockets
or glove box when the hybrid syst em is started or power switch modes
are changed.
● Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio w ave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping t he electronic
key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Even 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.
● The doors may unlock or lock if a large amount of water splashes on the
door handle, such as in the rain or in a car wash when the elec tronic key is
within the effective range. (The doors will automatically be lo cked after
approximately 30 seconds if the doors are not opened and closed .)
● If 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 m ay not be
unlocked by the entry function. (Use the wireless remote contro l to unlock
the doors.)
● Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor aga in.
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that ca se, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 2 m (6 ft.) or more awa y from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the s mart entry &
start system. ( P. 207)

WARNING
■Caution regarding interference with electronic devices
● People with implantable cardiac pacemakers, cardiac resynchronization
therapy-pacemakers or implantable cardioverter defibrillators should main-
tain a reasonable distance between themselves and the smart ent ry &
start system antennas. ( P. 205)
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.
● Users of any electrical medical device other than implantable cardiac
pacemakers, cardiac resynchronization therapy-pacemakers or imp lant-
able cardioverter defibrillators should consult the manufacture r 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.
