3-2. Opening, closing and locking the doors and trunk
CAUTION
■Trunk easy closer (vehicles with power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles 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
trunk is about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may suddenly shut after it opens automatically. Make
sure the trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine switch is
turned to IGNITION ON mode or the engine is started during automatic
operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not op erate, causing itself to malfunction, or
the trunk lid may suddenly shut again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.
