Operation of each component
To take out the mechanical key,
slide the release lever and take
the key out.
The mechanical key can only be
inserted in one direction, as the
key only has grooves on one side.
If the key cannot be inserted in a
lock cylinder, turn it over and re-
attempt to insert it.
After using the mechanical key, store it in the electronic key. Carry the
mechanical key together with the electronic key. If the electronic key bat-
tery is depleted or the entry function does not operate properly, you will
need the mechanical key. (→P. 726)
■Panic mode
■ If you lose your mechanical keys
New genuine mechanical keys can be made by your Toyota dealer using
another mechanical key and the key number stamped on your key number
plate. Keep the plate in a safe place such as your wallet, not in the vehicle.

When bringing an electronic key onto an aircraft, make sure you do not press
any buttons on the electronic key while inside the aircraft cabin. If you are
carrying an electronic key in your bag etc., ensure that the buttons are not
likely to be pressed accidentally. Pressing a button may cause the electronic
key to emit radio waves that could interfere with the operation of the aircraft.

●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. 646)
• The smart key 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. 646). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by your Toyota dealer.

(1 m) of the following electrical appliances that produce a magnetic field:

Operation of each component
■Alarms and warning messages
An alarm sounds and warning message displays shown on the multi-informa-
tion display are used to protect against unexpected accidents or theft of the
vehicle resulting from erroneous operation. When a warning message is dis-
played, take appropriate measures based on the displayed message.
When only an alarm sounds, circumstances and correction procedures are as
follows.

played on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.

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 in operation for a long time.

unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.

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 t\
he
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 door will automatically be locked after approximately
60 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.
● When the lock operation is performed using the lock sensor, recognition sig-
nals 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 6 ft. (2 m) 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 key sys-
tem. ( →P. 184)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.

nal position and check that the doors unlock before pulling the door handle
again.

longer to unlock the doors after the door handle is gripped.
