Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, 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. 821)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
When the electronic key is in contact with, 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
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
If window tint with a metallic content or metallic objects are attached to the
rear window

Operation of each component
GS350/250_EE (OM30C36E)
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.)

When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 2 m
(6 ft.) of the vehicle.
The smart entry & start system can be deactivated in advance. (P. 855)
Alarm (if equipped)
Using the smart entry & start system to lock the doors will set the alarm sys-
tem.
(P. 86)
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 function
may not operate.)
Do not leave the electronic key inside the luggage compartment.
The key confinement prevention function may not operate, depending on
the location of the key (close to a spare tire [if equipped], the inside edge of
the luggage compartment), conditions (inside a metal bag, close to metallic
objects) and the radio waves in the surrounding area. (P. 152)
If the smart entry & start system does not operate properly
Locking and unlocking the doors and opening the trunk: Use the mechani-
cal key.

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.
