■Note for the entry function
●Even when the electronic key is within the effective range (detection areas), the
system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked.
• The electronic key is near the ground or in a high place, or too close to the
rear bumper center when the trunk is unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in
the door pockets or glove box when the hybrid system is started or
“POWER” switch modes are changed.
●Do not leave the electronic key on top of the instrument panel or near the door
pockets when exiting the vehicle. Depending on the radio wave reception con-
ditions, it may be detected by the antenna outside the cabin and the door will
become lockable from the outside, possibly trapping the electronic key inside
the vehicle.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●Even if the electronic key is not inside the vehicle, it may be possible to start the
hybrid system if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash when the electronic key is within the effective
range. (The door will automatically be locked after approximately 60 seconds if
the doors are not opened and closed.)
●Gripping the door handle when wearing a glove may not unlock the door.
●If the wireless remote control is used to lock the doors when the electronic key
is near the vehicle, there is a possibility that the door may not be unlocked by the
entry function. (Use the wireless remote control to unlock the doors.)
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the original
position and check that the doors unlock before pulling the door handle again.

■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get the
electronic key too close to the vehicle when operating the system from the outside
of the vehicle.
Depending on the position and holding condition of the electronic key, the key may
not be detected correctly and the system may not operate properly. (The alarm may
go off accidentally, or the door lock prevention may not operate.)

and a half.)
●If the battery becomes low, an alarm will sound in the cabin when the hybrid sys-
tem stops. ( →P. 5 2 4 )
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indicate
that the electronic key battery may be depleted. Replace the battery when nec-
essary. ( →P. 4 6 7 )
• The smart access system with push-button start or the wireless remote con- trol does not operate.

■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 put 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.

CAUTION
■Caution while driving
●Keep the trunk lid closed while driving.
If the trunk lid is left open, it may hit near-by objects while driving or luggage in
the trunk may be unexpectedly thrown out, causing an accident.
In addition, exhaust gases may enter the vehicle, causing death or a serious
health hazard. Make sure to close the trunk lid before driving.
●Before driving the vehicle, make sure that the trunk lid is fully closed. If the trunk
lid is not fully closed, it may open unexpectedly while driving, causing an accident.
●Never let anyone sit in the trunk. In the event of sudden braking or a collision, they
are susceptible to death or serious injury.
■When children are in the vehicle
Observe the following precautions.
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 have heat exhaustion or
suffocate.
●Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to operate unexpectedly, or cause the child’s
hands, head, or neck to be caught by the closing trunk lid.

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 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.
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.
●When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.
