●Even when the spare electronic key is put in the trunk with all the doors locked, the key
confinement prevention function can be activ ated 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 plac es and the surrounding radio wave condi-
tions. 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

■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, thor oughly check to make sure the surround-
ing 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 tr unk 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 opener and
closer: 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 unexpect-
edly opening or closing by itself. Make sure
that the trunk lid is fully open and secure
before using the trunk.

■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 any-

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 opener and closer may detect an abnor-
mality and automatic operation may be stoppe d. In this case, the trunk lid has to be
operated manually. Take extra care in this situation, as the stopped trunk lid may sud-
denly shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the power switch is turned to ON mode or the hybrid syst em 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 operat e, causing itself to malfunction, or the
trunk lid may suddenly shut again after it is opened.

ES300h_OM_OM33B71U_(U)3-2. Opening, closing and
locking the doors and trunk
■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 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 hybrid system is started or power 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 doors will become lockable from the
outside, possibly trapping the el ectronic 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 door s detecting the electronic key can be used
to unlock the vehicle.
●Even if the electronic key is not inside the ve hicle, it may be possible to start the hybrid
system if the electronic key is near the window.
●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 th e electronic key is within the effective range.
(The doors will automatically be locked after approximately 60 seconds if the doors
are not opened and closed.)
●If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or
unlock operation.
●If the door handle becomes wet while the el ectronic 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 6 ft. (2 m) 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 access system with push-button start. ( P. 1 2 3 )
●If the electronic key is insi de the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-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 detection area, it may take slightly longer to
unlock the doors after the door handle is gripped.

mately 3 seconds.
■Recalling the driving position using the memory recall function
●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart access system with

Operation of each component
When the mirror select switch is in the L or R position, the outside rear view mir-
rors will automatically angle downwards when the vehicle is reversing in order to
give a better view of the ground.
To disable this function, move the mirror select switch to the neutral position
(between L and R).
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position. The
adjusted angle will be memorized and the mirror will automatically tilt to the
memorized angle whenever the shift lever is shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, the tilt position will also change. When the normal
position is changed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to also defog the outside rear view mirrors. ( P. 3 8 8 )
■Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 1 3 0 )
■Auto anti-glare function
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. ( P. 1 4 0 )
