1-2. Key information
1
Before driving
Using the mechanical key (vehicles with a smart key system)
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 battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key.
(P. 473)
■ Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a key (without a smart key system) or mechanical key (with a
smart key system) is lost, a new key can be made by your Toyota dealer
using the key number plate. ( P. 472)
■ When riding in an aircraft
When bringing a key with wireless remote control function onto an aircra\
ft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons
are not likely to be pressed accidentally. Pressing a button may cause the
key to emit radio waves that could interfere with the operation of the a\
ircraft.

■
Switching the door unlock function
It is possible to set which doors the entry function unlocks using the wireless
remote control.
Turn the “POWER” switch off.
When the indicator light on the key surface is not on, press and
hold or for about 5 seconds while pressing and holding
.
The setting changes each time an operation is performed, as shown below.
(When changing the setting continuously, release the buttons, wait for at
least 5 seconds, and repeat step 2.)
■ Battery-saving function
The battery-saving function will be activated in order to prevent the elec-
tronic key battery and the 12-volt battery from being discharged while the
vehicle is not in operation for a long time.
●In the following situations, the smart key system may take some time to
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.
● If the smart key system has not been used for 14 days or longer, the
doors cannot be unlocked at any of the doors except the driver’s door. In
this case, take hold of the driver’s door handle, or use the wireless
remote control or the mechanical key, to unlock the doors.

■Electronic key battery-saving function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.

Conditions affecting operation
The smart key system uses weak radio waves. In the following situations,
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. 473)
● 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 electri-
cal 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 wireless com-
munication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to
the rear window
● When the electronic key is placed near a battery charger or electronic
devices

56 1-3. Opening, closing and locking the doors
■Notes 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, luggage cover or 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 instrument
panel or near the door pockets. Depending on the radio wave reception
conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the elec-
tronic key inside the vehicle.
● As long as the electronic key is within the effective range, the doors may
be locked or unlocked by anyone.
● Whether or not the electronic key is inside the vehicle, the hybrid 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
handle, 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.)
● The lock and unlock sensors may not work properly if they come into
contact with ice, snow, mud, etc. Clean the sensors and attempt to oper-
ate them again.
● If the wireless remote control is used to lock the doors when the elec-
tronic key is near the vehicle, there is a possibility that the door may not
be unlocked by the entry function. (Using the wireless remote control to
unlock the doors may resume the function.)
● If the door handle becomes wet while the electronic key is within the
effective 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 6 ft. (2 m) 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 key system. ( P. 54)

58 1-3. Opening, closing and locking the doors
■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 when the
hybrid system stops. (P. 449)
● As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 397)
• 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.
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) 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
• Glass top ranges
• Table lamps
■ When the electronic key battery is fully depleted
P. 397
■ If the smart key system has been d eactivated in a customized setting
● Locking and unlocking the doors: Use the wireless remote control or
mechanical key. ( P. 61, 473)
● Starting the hybrid system and changing “POWER” switch modes:
P. 474
● Stopping the hybrid system: P. 474
■ Customization that can be co nfigured at Toyota dealer
Settings (e. g. operation signals) can be changed.
