■ 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. 561)
• 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.
The battery can be exchanged by the users. ( P. 561) However, as there
may be damage to the key when exchanging, it is recommended to have
the battery exchanged at any authorized Toyota retailer or Toyota autho-
rized 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
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers

■ When “Entry & Start System Malfunction. See Owner’s Manual.” is dis-
played on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
■ Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the 12-volt battery from being discharged while the vehicle is
not operated for a long time.
● In the following situations, the smart entry & start system may take some
time to unlock the doors.
• The electronic key has been left within approximately 2 m (6 ft.) of the
outside of the vehicle for 10 minutes or longer.
• The smart entry & start system has not been used for 5 days or longer.
● If the smart entry & start system has not been used for 14 days or longer,
the doors cannot be unlocked at any doors except the driver’s door. In this
case, hold the driver’s door handle, or use the wireless remote control or
mechanical key to unlock the doors.
■ Electronic Key Battery-Saving Function

depletion is minimized by stopping the
electronic key from receiving radio waves.
Press twice while pressing and
holding . Confirm that the electronic
key indicator flashes 4 times.
While the battery-saving mode is set, the
smart entry & start system cannot be

■ Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situa-
tions, 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. 648)
● 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
● 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 wireless commu-
nication devices
• Another electronic key or a wireless key that emits radio waves
• Personal computers or pers onal digital assistants (PDAs)
• Digital audio players
• Portable game systems

■ 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 w hen the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to
the rear bumper center when the back door is opened.
• 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 out side, 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 doors 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.
● 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 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 the electronic key to battery-saving mode to disable the smart entry &
start system. ( P. 165)
