Operation of each component

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 panel, 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 the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the elec-
tronic 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 elec-
tronic key can be used to unlock the vehicle.
Even if the electronic key is not inside the vehicle, it may be possible to
start the engine if the electronic key is near the window.
The doors may unlock or lock 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 doors will automatically be locked after
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 door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)

GS350/250_EE (OM30C36E)
Note for locking the doors
Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
If the door handle becomes wet while the electronic key is within the effec-
tive 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 system. (P. 129)
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 dis-
play 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.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
Note for the unlocking function
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 origi-
nal 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 the door handle becomes wet while the electronic key is within the effec-
tive 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 system. (P. 129)
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.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is about a
year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
engine stops. (P. 779)
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 necessary. (P. 695)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Glass top ranges

CAUTION
Trunk easy closer (vehicles with power trunk lid)
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 obsta-
cles 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 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 fall 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 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 battery voltage suddenly drops, such as when the engine
switch is turned to IGNITION ON mode or the engine is started during
automatic operation
Do not attach any accessories other than genuine Lexus parts to the trunk
lid. The power trunk lid may not operate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.
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 seconds 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

CAUTION
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 belt 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 driving as the seat may unexpect-
edly move and cause the driver to lose control of the vehicle.
