Operation of each component
PRIUS c_U■
Conditions affecting operation
The smart key system uses weak radio waves. In the following si tuations, the
communication between the electronic key and the vehicle may be affected,
preventing the smart key system, wireless remote control and immobilizer
system from operating properly. (Ways of coping: P. 520)
● When the electronic key battery is depleted
● Near a TV tower, electric power plant, gas station, radio stati on, large dis-
play, airport or other facility that generates strong radio wav es or electrical
noise
● 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
• A portable radio, cellular phone, cordless phone or other wire less com-
munication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)

Notes for the entry function
●Even when the electronic key is within the effective range (det ection 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 on the instrument panel, luggage cover o r floor, in
the door pockets or glove box when the hybrid system is started or power
switch modes are changed.
● Do not exit the vehicle with the electronic key placed on the i nstrument
panel or near the door pockets. Depending on the radio wave reception con-
ditions, 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.
● As long as the electronic key is within the effective range, th e doors may be
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.
● Whether or not the electronic key is inside the vehicle, the hy brid system
could be started if the electronic key is near the window.
● The 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 k ey is within the
effective range. (The door will automatically be locked after a pproximately
60 seconds if the doors are not opened and closed.)
● The lock and unlock sensors may not work properly if they come into con-
tact with ice, snow, mud, etc. Clean the sensors and attempt to operate
them again.
● If the wireless remote control is used to lock the doors when t he electronic
key is near the vehicle, there is a possibility that the door m ay not be
unlocked by the entry function. (Using the wireless remote cont rol to unlock
the doors may resume the function.)
● If the door handle becomes wet while the electronic key is with in 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 6 ft. (2 m) 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 key
system. ( P. 142)
