Toyota Sienna (2019 year). Instruction — part 9

WARNING

When opening or closing the sliding doors with windows open, keep all
body parts clear of the windows.

If anyone is in the vicinity, make sure they are safe and let them know that
the sliding door is about to open or close.

Do not leave the sliding door at half-opened position because the sliding
door is not latched at this position. The sliding door may move unexpect-
edly on an incline.

When the vehicle is stopped on a slope,
the door will slide faster when opening
or closing, so be especially careful that
the passengers do not get hit or
pinched by the door.

Open the sliding door fully while pas-
sengers are getting on or off on a down-
ward slope. Do not operate the outside
handle or inside handle while the door
is open as the door could suddenly
close by itself causing injury.

When closing the sliding door, take
extra care to prevent your fingers etc.
from being caught.

WARNING

Sliding door closer (if equipped)

Use caution when using the sliding door closer. The sliding door closer
operates even when the power sliding door system is canceled.

Power sliding doors (vehicles with power sliding doors)
Observe the following precautions when the power sliding door system is
on.
Failure to do so may cause death or serious injury.

When using the door handle to open or close the power sliding door,
remove your hand from the door handle immediately after starting power
sliding door operation. If you leave your hand on the door handle during
operation, your hand, fingers, wrist etc. may be subjected to an excessive
amount of force.

Check the safety of the surrounding area to make sure there are no obsta-
cles or anything that could cause any of your belongings to get caught.

In the event that the sliding door is left
slightly open, the sliding door closer will
automatically close it to the fully closed
position. It takes several seconds
before the sliding door closer begins to
operate. Be careful not to catch fingers
or anything else in the sliding door, as
this may cause bone fractures or other
serious injuries.

Do not get in and out of the vehicle
while the power sliding door is being
operated.

If anyone is in the vicinity, make sure
they are safe and let them know that the
sliding door is about to open or close.
Also, do not operate the power sliding
door if anyone inside or outside the
vehicle is leaning against the vehicle in
the area around the sliding door.

WARNING

If the power sliding door system is turned off with the main switch while the
sliding door is operating automatically, the automatic operation is stopped.
The sliding door then has to be operated manually. Take extra care when
on an incline, as the sliding door may open or close unexpectedly.

If the operating conditions of the power sliding door are no longer met, a
buzzer may sound and the sliding door may stop opening or closing. The
sliding door then has to be operated manually. Take extra care when on an
incline, as the sliding door may open or close abruptly.

On an incline, a sliding door may close by itself after it opens automati-
cally. Make sure the sliding door is fully open and secure.

In the following situations, the power sliding door may detect an abnormal-
ity and automatic operation may be stopped. In this case, the sliding door
has to be operated manually. Take extra care when on an incline, as the
sliding door may open or close abruptly.
• When the sliding door contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine

switch is turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system) or the
engine is started during automatic operation

Do not attach any accessories other than genuine Toyota parts to the
power sliding door. The power sliding door may not operate, causing itself
to malfunction, or the power sliding door may close again after it is
opened.

When the child-protector locks are set, make sure to turn off the power
sliding door system with the main switch in order to totally disable the sys-
tem.

Jam protection function (vehicles with power sliding doors)
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 power sliding door fully closes. Be careful not to catch fingers or
anything 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.

WARNING

Observe the following precautions.
Failure to do so may result in death or serious injury.

Before driving

Make sure that the back door is fully closed. If the back door is not fully
closed, it may open unexpectedly while driving and hit near-by objects or
luggage in the luggage compartment may be thrown out, causing an acci-
dent.

Do not allow children to play in the luggage compartment.
If a child is accidentally locked in the luggage compartment, they could
have heat exhaustion or other injuries.

Do not allow a child to open or close the back door.
Doing so may cause the back door to operate unexpectedly, or cause the
child’s hands, head, or neck to be caught by the closing back door.

Important points while driving
Never let anyone sit in the luggage compartment. In the event of sudden
braking, sudden swerving or a collision, they are susceptible to death or
serious injury.

Operating the back door
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in death
or serious injury.

Remove any heavy loads, such as snow and ice, from the back door
before opening it. Failure to do so may cause the back door to suddenly
shut again after it is opened.

When opening or closing the back door, thoroughly check to make sure
the surrounding area is safe.

If anyone is in the vicinity, make sure they are safe and let them know that
the back door is about to open or close.

Use caution when opening or closing the back door in windy weather as it
may move abruptly in strong wind.

The back door may suddenly shut if it is
not opened fully. It is more difficult to
open or close the back door on an
incline than on a level surface, so
beware of the back door unexpectedly
opening or closing by itself. Make sure
that the back door is fully open and
secure before using the luggage com-
partment.
