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. 189)

3-2. Opening, closing and locking the doors

●

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.

●

The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.

●

A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.

●

If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped. 

■

When the vehicle is not driven for extended periods

●

To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.

●

The smart entry & start system can be deactivated in advance. (



P. 670)

■

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 operate.)

■

If the smart entry & start system does not operate properly

●

Locking and unlocking the doors: Use the mechanical key. (

WARNING

■

Caution regarding interference with electronic devices

●

People with implantable cardiac pacemakers, cardiac resynchronization
therapy-pacemakers or implantable cardioverter defibrillators should keep
away from the smart entry & start system antennas. (



P. 187) 

The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details, such as the
frequency of radio waves and timing of the emitted radio waves. Then,
consult your doctor to see if you should disable the entry function.

●

Users of any electrical medical device other than implantable cardiac
pacemakers, cardiac resynchronization therapy-pacemakers or implanta-
ble cardioverter defibrillators should consult the manufacturer of the
device for information about its operation under the influence of radio
waves.
Radio waves could have unexpected effects on the operation of such
medical devices.

Ask any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer for details on disabling the entry function.

WARNING

■

When adjusting the seat position

●

Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.

●

Do not put your hands under the seat or near the moving parts to avoid
injury. 
Fingers or hands may become jammed in the seat mechanism.

■

Seat adjustment

●

To reduce the risk of sliding under the lap belt during a collision, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply
restraint forces directly to the abdomen, or your neck may contact the
shoulder belt, increasing the risk of death or serious injury in the event of
an accident. 
Adjustments should not be made while driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.

●

After adjusting the seat, make sure that the seat is locked in position.
