■Function to prevent the trunk being locked with the electronic key inside
●When all doors are being locked, closing the trunk lid with the electronic key left
inside the trunk will sound an alarm. 
In this case, the trunk lid can be opened using the entry function.
●Even when the spare electronic key is pu t in the trunk with all the doors locked,
the key confinement prevention function can be activated so the trunk can be
opened. In order to prevent theft, take all electronic keys with you when leaving
the vehicle.
●Even when the electronic key is put in the trunk with all the doors are locked, the
key may not be detected depending on the places and the surrounding radio
wave conditions. In this case, the key confinement prevention function cannot
be activated, causing the doors to lock when the trunk is closed. Make sure to
check where the key is before closing the trunk.
●The key confinement prevention function cannot be activated if any one of the
doors is unlocked. In this case, open the trunk using the trunk opener.

are susceptible to death or serious injury.

Failure to do so may result in death or serious injury.
●Do not allow children to enter the trunk. 
If a child is accidentally locked in the trunk, they could overheat or suffocate.

■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 an d ice, from the trunk lid before opening
it. Failure to do so may cause the trunk lid to fall closed 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 fall closed again after
it is opened.
●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 unex-
pectedly opening or closing by itself.

and secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
