■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious

●Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on th e trunk lid may cause the lid to fall closed again after

●The trunk lid may fall 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

●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

●On an incline, the trunk lid may fall afte r 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

power trunk opener and closer may not op erate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.

gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
