Installation of an RF-transmitter system
The installation of an RF-transmitter system in your vehicle could affect
electronic systems such as:
Multiport fuel injection system/sequential multiport fuel injection system
Cruise control system
Dynamic radar cruise control system
Anti-lock brake system
SRS airbag system
Seat belt pretensioner system
Be sure to check with any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional for precautionary measures or spe-
cial instructions regarding installation of an RF-transmitter system.
Further information regarding frequency bands, power levels, antenna posi-
tions and installation provisions for the installation of RF-transmitters, is
available on request at any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
Scrapping your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, before you scrap your vehicle.

To prevent key damage
Observe the following:
Do not drop the keys, subject them to strong shocks or bend them.
Do not expose the keys to high temperatures for a long period of time.
Do not get the keys wet or wash them in an ultrasonic washer etc.
Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
Do not disassemble the keys.
Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems, glass top ranges, or medical electrical equipment,
such as low-frequency therapy equipment.
Precautions for handling the card keys
Do not apply excess force when inserting the mechanical key to the card
key. Doing so may damage the card key.
If the battery or card key terminals get wet, the battery may corrode and
the card key may stop working.
If the key is dropped into water, or if drinking water etc. is spilled on the
key, immediately remove the battery cover and wipe the battery and ter-
minals. (To remove the battery cover, lightly grasp and pull it.) If the bat-
tery is corroded, have any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional, replace the battery.
Do not crush the battery cover or use a screwdriver to remove the battery
cover. Forcibly removing the battery cover may bend or damage the key.
If the battery cover is frequently removed, the battery cover may become
loose.
When installing the battery, make sure to check the direction of the bat-
tery.
Installing the battery in the wrong direction may cause the battery to
deplete rapidly.
The surface of the card key may be damaged, or its coating may peel off
in the following situations.
• The card key is carried together with hard objects, such as coins or
keys.
• The card key is scraped with a sharp object, such as a tip of mechanical
pencil.
• The surface of the card key is wiped with thinners or benzene.

Operation signals
Doors: The emergency flashers flash to indicate that the doors have been
locked/unlocked. (Locked: Once; Unlocked: Twice)
Windows and moon roof: A buzzer sounds to indicate that the windows and
moon roof are operating.
Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following sit-
uations, the communication between the electronic key and the vehicle may
be affected, preventing the smart entry & start system and wireless remote
control from operating properly:
(Ways of coping: P. 458)
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 elec-
trical noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication devices
When the electronic key is in contact with, or is covered by the follow-
ing 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 multiple electronic keys are in the vicinity
When another wireless key (that emits radio waves) is being used nearby
When carrying or using 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 computer or personal digital assistant (PDA)
• Digital audio player
• Portable game system
If window tint with a metallic content or metallic objects are attached to

Switching the door unlock function
It is possible to set which doors the entry function unlocks.
Turn the “ENGINE START STOP” switch OFF.
Cancel the intrusion sensor of the alarm system to prevent unin-
tended triggering of the alarm during the setting change. (P. 97)
When the indicator on the key surface is turned off, push and
hold or for approximately 5 seconds while pushing
on the key.
The setting changes each time an operation is performed, as shown below.
(When changing the setting continuously, release the buttons, wait for at
least 5 seconds, and repeat step 3.)
To prevent unintended triggering of the alarm, unlock the doors using the
wireless remote control and open and close a door once after the settings
have been changed. (If a door is not opened within 30 seconds after is
pressed, the doors will be locked again and the alarm will automatically be
set.)
In case that the alarm is triggered, immediately stop the alarm. (P. 9 7 )

Battery-saving function
In the following circumstances, the entry function is disabled in order to
prevent the vehicle and electronic key batteries from discharging.
When the entry function has not been used for 30 days or more
When the electronic key has been left within approximately 1 m (3 ft.) of
the vehicle for 10 minutes or more
The system will resume operation when...
The vehicle is locked using the door handle lock switch.
The vehicle is locked/unlocked using the wireless remote control func-
tion.
(P. 52)
The vehicle is locked/unlocked using the mechanical key. (P. 458)
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. 440)
The battery becomes depleted even if the electronic key is not used
because the key always receives radio waves. If the smart entry & start
system or the wireless remote control does not operate, or the detection
area becomes smaller, the battery may be depleted. Replace the battery
when necessary.
(P. 388)
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
• Glass top ranges
• Table lamps
