Toyota Sienna (2019 year). Instruction — part 10

Battery-saving function
In the following circumstances, the entry function is disabled in order to pre-
vent the vehicle battery from discharging and the electronic key battery from
discharging.

When the entry function has not been used for 5 days or more

When the electronic key has been left within approximately 6 ft. (2 m) of the
vehicle for 10 minutes or more

If the entry function has not been used for 14 days or more, the vehicle can-
not be unlocked by a door other than the driver’s door. To unlock the vehicle,
grip the driver’s door handle or use the wireless remote control or the
mechanical key.

The system will resume operation when...

The vehicle is locked using the lock sensor when carrying the electronic key
on your person.

The vehicle is locked/unlocked using the wireless remote control. (

P. 111)

The vehicle is locked/unlocked using the mechanical key. (

P. 503)

Conditions affecting operation
P. 119

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, floor or in the glove box

when the engine is started or engine 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
locked or unlocked by anyone. However, only the doors detecting the elec-
tronic key can be used to unlock the vehicle.

The doors may unlock or lock 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 doors 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 smart key system. (Use the wireless remote control to
unlock the doors.)

If power slide door is unable to operate due to prohibition by the power slid-
ing door main switch, the door unlock and open operation will not be per-
formed. (

P. 124)

Note for locking 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. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)

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, or
use the lock sensor on the lower part of the door handle.

Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

Notes for the unlocking function

Gripping the front door handle when wearing a glove may not unlock or lock
the door.

A sudden approach to the effective range or door handle operation may pre-
vent the doors from being unlocked. In this case, return the door handle to
the original position and check that the doors have unlocked before pulling
the door handle.

If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after one of the front door handles is gripped or
one of sliding door handles is pulled.

When the vehicle is not driven for extended periods

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

The smart key system can be deactivated in advance. (

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 key system does not operate properly

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

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 key system antennas. (

P. 143)

The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask your Toyota dealer 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 implant-
able 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.

Adjustment procedure

150

SIENNA_OM_OM08025U_(U)

When the occupant’s lower back
presses against the seatback
during a rear-end collision, the
head restraint moves slightly for-
ward and upward to help reduce
the risk of whiplash on the seat
occupant.

Active head restraints
Even small forces applied to the seatback may cause the head restraint to
move. When a locked head restraint is pushed up forcibly, the head restraint
inner structure may appear. This does not indicate a problem.

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.

Make sure to leave enough space around the feet so they do not get stuck.

Seat adjustment

Be careful that the seat does not hit passengers or luggage.

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 reclined too far, 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.

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