locked/unlocked. (Locked: Once; Unlocked: Twice)

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. 516)
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

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 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. 55)
The vehicle is locked/unlocked using the mechanical key. (P. 516)
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. 481)
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. 431)
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

CAUTION
Caution regarding interference with electronic devices
People with implanted pacemakers or cardiac defibrillators should main-
tain a reasonable distance between themselves and the smart entry & start
system antennas. (P. 3 9 )
The radio waves may affect the operation of such devices. If necessary,
the entry function can be disabled. Ask any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional, 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 entry
function.
User 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 med-
ical devices.
Ask any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for details for disabling the entry function.
