WARNING■
Back door closer●
In the event that the back door is left
slightly open, the back door closer will
automatically close it to the fully closed
position. It takes several seconds
before the back door closer begins to
operate. Be careful not to catch fingers
or anything else in the back door, as
this may cause bone fractures or other
serious injuries.
●
Use caution when using the back door
closer as it still operates when the
power back door system is canceled.
■
Power back door
Observe the following precautions when
operating the power back door.
Failure to do so may cause death or seri-
ous injury.
●
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. ●
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. ●
If the power back door system is
turned off with the main switch while
the back door is operating automati-
cally, the automatic operation is
stopped. The back door then has to be
operated manually. Take extra care
when on an incline, as the back door
may open or close unexpectedly. ●
If the operating conditions of the
power back door are no longer met, a
buzzer may sound and the back door
may stop opening or closing. The back
door then has to be operated manu-
ally. Take extra care when on an incline,
as the back door may open or close
abruptly. ●
On an incline, the back door may sud-
denly shut after it opens. Make sure
the back door is fully open and secure. ●
In the following situations, the power
back door may detect an abnormality
and automatic operation may be
stopped. In this case, the back door
has to be operated manually. Take
extra care when on an incline, as the
back door may open or close abruptly.
• When the back door contacts an
obstacle
• When the 12-volt battery voltage sud-
denly drops, such as when the power
switch is turned to power ON mode or
the hybrid system is started during
automatic operation
●
If a bicycle carrier or similar heavy
object is attached to the back door, the
power back door may not operate,
causing itself to malfunction, or the
back door may suddenly shut again
after being opened, causing some-
one’s hands, head or neck to be caught
and injured. When installing an acces-
sory part to the back door, using a
genuine Lexus part is recommended.
