■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors have
been locked/unlocked. (Locked: Once; Unlocked: Twice)
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start, wire-
less remote control and immobilizer system from operating properly: 
(Way of coping: P. 5 7 1 )
●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 carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices
●When the electronic key is in contact with, or is covered by the following metal-
lic 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 other wireless keys (that emit radio waves) are 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 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

Unlock the doors using the wireless remote control and open one of the
doors.
If a door is not opened within 60 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. 8 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 a month or more
●When the electronic key has been left within approximately 3 ft. (1 m) 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 function 
(P. 41) or the mechanical key (P. 5 7 1 )
■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. 3 7 )
●The battery becomes depleted even if the electronic key is not used because
the key always transmits radio waves. If the smart access system with push-but-
ton start or the wireless remote control does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when nec-
essary. ( P. 4 8 2 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) 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

■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 may not function.)
■Note for the smart access system with push-button start
●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 unlocked.
• The electronic key is on the instrument panel, rear package tray or floor, or in
the glove box when the engine is started or “ENGINE START STOP” switch
modes are changed.
●As long as the electronic key is within the effective range, the doors may be
locked or unlocked by anyone.
●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 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 60 seconds
if the doors are not opened and closed.)

●Gripping the door handle when wearing a glove may not unlock the door.
●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
smart access system with push-button start. (Use the wireless remote control to
unlock the doors.)
●A sudden approach to the effective range or door handle operation may pre-
vent 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.
■When the vehicle is not driven for extended periods
To prevent theft of the vehicle, do not leave the electronic key within 6 ft. (2 m) of
the vehicle.
■Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the theft deterrent system automatically locks the vehicle again.
■Alarms and warning indicators
A combination of exterior and interior alarms as well as warnings displayed on the
multi-information display are used to prevent theft of the vehicle and unforeseeable
accidents resulting from erroneous operation. Take appropriate measures in
response to any warning indications on the multi-information display. (P. 5 5 3 )
The following table describes circumstances and correction procedures when only
alarms are sounded.

CAUTION
■Caution regarding interference with electronic devices
●People with implanted pacemakers or cardiac defibrillators should keep away
from the smart access system with push-button start antennas. (P. 3 1 ) T h e
radio waves may affect the operation of such devices. If necessary, the smart
access system with push-button start can be disabled. Ask your Lexus dealer for
details, such as the frequency of radio waves and timing of emitting the radio
waves. Then, consult your doctor to see if you should disable the smart access
system with push-button start.
●Users of any electrical medical device other than implanted pacemakers and
implanted cardiac defibrillators should consult the manufacturer of the device for
information about its operation under the influence of radio waves. Radio waves
could have unexpected effects on the operation of such medical devices.
Ask your Lexus dealer for details for disabling the smart access system with push-but-
ton start.
