Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors
have been locked/unlocked. (Locked: Once; Unlocked: Twice)
■ 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 and wireless remote control from
operating properly. (Ways of coping: P. 596)
● 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 carrying a portable radio, ce llular phone, cordless phone or other
wireless communication devices
● When the electronic key is in contact with, or is covered by a metallic
object
● When multiple electronic keys are in the vicinity
● When carrying or using the electronic key together with the following
devices that emit radio waves
• Another vehicle’s electronic key
• A wireless key that emits radio waves
• Personal computer
● If window tint with a metallic content or metallic objects are attached to
the rear window
■ Switching the door unlock function
It is possible to set which doors the entry function unlocks.
Turn the “POWER” switch OFF.
When the indicator on the key surface is turned off, push and hold
, or for approximately 5 seconds while pushing
on the key.

54 1-3. Opening, closing and locking the doors
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.)To prevent unintended triggering of the alarm, unlock the doors using the
wireless remote control and open and close a door once after the settings
have been changed. (If a door is not opened within 60 seconds aft-
er is pressed, the doors will be locked again and the alarm will auto-
matically be set.)
In case that the alarm is triggered, immediately stop the alarm. ( P. 129)
■ Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the 12-volt battery from discharging and the electronic key battery from
depleting.
●When the entry function has not been used for 2 weeks or more
● When the electronic key has been left within approximately 3 ft. (1 m) of
the vehicle for 10 minutes or more
The system will resume operation when...
● The vehicle is locked using the door handle lock button.
● The vehicle is locked/unlocked using the wireless remote control func-
tion. ( P. 6 1 )

Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart key system or the
wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when
necessary. ( P. 533)
● If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 56)
● 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
• Recharging cellular phones or cordless phones
• Table lamps
■ To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)
■ 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, luggage cover, floor or in the 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
reception 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.

CAUTION
●
On an incline, the back door may suddenly shut after it opens automati-
cally. Make sure the back door is fully open and secure.
● In the following situations, the power back door may detect an abnormali\
ty
and automatic operation may be stopped. In this case, the back door has
to be operated manually. Take extra care in this situation, as the stopped
back door may suddenly shut, causing an accident.
• When the back door contacts an obstacle
• Vehicles without smart key system: When the battery voltage suddenly
drops, such as when the engine switch is turned to the “ON” position or
the hybrid system is started during automatic operation
• Vehicles with smart key system: When the battery voltage suddenly drops, such as when the “POWER” switch is turned to ON mode or the
hybrid system is started during automatic operation
● Do not attach any accessories other than genuine Toyota parts to the back
door. The power back door may not operate, causing itself to malfunction,
or the back door may suddenly shut again after it is opened.
■ Jam protection function (vehicles with power back door)
Observe the following precautions.
Failure to do so may cause death or serious injury.
●Never use any part of your body to intentionally activate the jam protection
function.
● The jam protection function may not work if something gets caught just
before the back door fully closes. Be careful not to catch fingers or any-
thing else.
● The jam protection function may not work depending on the shape of the
object that is caught. Be careful not to catch fingers or anything else.
