■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin and a message
will be displayed on the multi-information display when the hybrid system
stops.
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 688)
• 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.
You can replace the battery by yourself (P. 688). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
●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
• Table lamps
• Induction cookers

from operating properly. (Ways of coping: P. 751)
●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 electrical
noise

Operation of each component
■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 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.
●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 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.
●As long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.
●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 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.)
●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 may not be
unlocked by the entry function. (Use the wireless remote control 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 again.
●On 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.
●If 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. 295)
