■Trunk easy closer
■Power trunk lid (If equipped)
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or any-
thing 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 lid may detect an abnormality and auto-
matic operation may be stopped. In this case, the trunk lid has to be operated manu-
ally. 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 opera-
tion
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk lid may not operate, causing itse lf to malfunction, or the trunk lid may
suddenly shut again after it is opened.
■Jam protection function (vehicles with power trunk lid)
Observe the following precautions.
Failure to do so may cause serious injury.
●Never use any part of your body to intent ionally activate the jam protection function.
●The jam protection function may not work if something gets caught just before the
trunk lid fully closes. Be careful not to catch fingers or anything else in the trunk lid.
●The jam protection function may not work depending on the shape of the object that
is caught. Be careful not to catch fingers or anything else.
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 sec-
onds before the trunk easy closer begins to
operate. Be careful not to catch fingers or any-
thing else in the trunk lid, as this may cause
bone fractures or other serious injuries.

■Electronic Key Battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the elec-
tronic key from receiving radio waves.
■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations, the
communication between the electronic key and the vehicle may be affected, preventing
the smart entry & start system, wireless remote control and engine immobilizer system
from operating properly. (Ways of coping: →P. 5 8 8 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display, airport or
other facility that generates strong radio waves or electrical noise
●When the electronic key is in contact wi th, or is covered by the following metallic
objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying the electronic key together with the following devices that emit radio
waves
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)

■Note for the entry function (if equipped)
●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 theground, 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 opened.
• The electronic key is on the instrument pa nel, rear package tray or floor, or in the
door pockets or glove box when the engine is started or engine switch modes are
changed.
●Do not leave the electronic key on top of th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, 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. However, only the doors detecting the electronic key can be used
to unlock the vehicle.
●The doors may unlock or lock if a large amou nt 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 doors will automatically be locked af ter approximately 30 seconds if the doors
are not opened and closed.)
●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 d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock sensor while wearing gloves may delay or prevent lock opera-
tion.
●If the door handle becomes wet while the electronic key is within the effective range,
the door may lock and unlock repeatedly. In that case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry & start sys- tem. ( →P. 1 7 5 )
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the multi-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc.
Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●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.
●Gripping the door handle when wearing a glove may not unlock the door.
●If there is another electronic key in the de tection area, it may take slightly longer to
unlock the doors after the door handle is gripped.

■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the seat mechanism.
■Seat adjustment
To reduce the risk of sliding under the lap be lt during a collision, do not recline the seat
more than necessary.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
