Operation of each component
CAUTION
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious
injury.
●Remove any heavy loads, such as snow and ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to suddenly shut again after it is opened.
●When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to suddenly shut again
after it is opened.
●Vehicles without power trunk lid: The trunk
lid may suddenly shut if it is not opened fully.
It is more difficult to open or close the trunk
lid on an incline than on a level surface, so
beware of the trunk lid unexpectedly open-
ing or closing by itself. Make sure that the
trunk lid is fully open and secure before
using the trunk.
●When closing the trunk lid, take extra care
to prevent your fingers etc. from being
caught.
●Vehicles without power trunk lid: When
closing the trunk lid, make sure to press it
lightly on its outer surface. If the trunk grip
is used to fully close the trunk lid, it may
result in hands or arms being caught.

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 fall 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 fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the “START STOP ENGINE” <“POWER”> 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 operate, causing itself to malfunction, or
the trunk lid may fall closed 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.
