Operation of each component
■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key bat-
tery and the vehicle battery from being discharged while the vehicle is not in operation
for a long time.
●In the following situations, the smart acce ss system with push-button start may take
some time to unlock the doors.
• The electronic key has been le ft in an area of approximately 6 ft. (2 m) of the outside
of the vehicle for 10 minutes or longer.
• The smart access system with push-button st art has not been used for 5 days or lon-
ger.
●If the smart access system with push-button start has not been used for 14 days or lon-
ger, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s d oor handle, or use the wireless remote control or the mechan-
ical key, to unlock the doors.
■Electronic Key Battery-Saving Function
●When battery-saving mode is set, battery de pletion is minimized by stopping the elec-
tronic key from re ceiving radio waves.
●Electronic keys that will not be used for long periods of time can be set to the battery-
saving mode in advance.
■Conditions affe cting operation
The smart access system with push-button st art uses weak radio waves. In the following
situations, the communication between the electronic key and the vehicle may be
affected, preventing the smar t access system with push-but ton start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping: P. 540)
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas st ation, radio station, large display, airport or
other facility that generates strong radio wave s or electrical noise
●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 Press twice while pr essing and holding
. Confirm that the el ectronic key indi-
cator flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function, press
any of the electronic key buttons.

waves
• Portable radio, cellular phone, cordle
ss phone or other wireless communication
devices
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or me tallic objects are attached to the rear win-
dow
●When the electronic key is placed near a battery charger or electronic devices
●When the vehicle is parked in a pay parking spot where radio waves are emitted
■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 on the instrument pa nel, luggage cover 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 th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outside the cabin an d the doors will become lockable from the
outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within th e effective range, the doors may be locked or
unlocked by anyone. However, only the door s detecting the electronic 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 lock or unlock if a large amount of water splashes on the door handle,
such as in the rain or in a car wash, when th e electronic key is within the effective range.
(The doors will automatically be locked afte r approximately 60 seconds if the doors or
the glass hatch are not opened and closed.)
●If the wireless remote control is used to lo ck the doors when the electronic key is near
the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock sensor while we aring gloves may prevent lock operation.
●When the lock operation is performed using the lock sensor, recognition signals will be
shown up to two consecutive times. After this, no recognition signals will be given.
*
●If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow the following correction
procedures to wash the vehicle.
• Place the electronic key in a location 6 ft. (2 m) or more away from the vehicle. (Take care to ensure that the key is not stolen.)

Operation of each component
●If the electronic key is inside the vehicle and a door handle becomes wet during a car
wash, a buzzer may sound outside the ve hicle and “KEY DETECTED IN VEHICLE”/
“Key detected in vehicle” may be shown on th e multi-information display. 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.
●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 original position and check
that the doors unlock before pulling the door handle again.

●People with implantable cardiac pacema kers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter de fibrillators should keep away from the
smart access system antennas. ( P. 121)
The radio waves may affect the operation of such devices. If necessary, the entry
function can be disabled. Ask your Lexus dealer for details, such as the frequency of
radio waves and timing of the emitted radio waves. Then, consult your doctor to see if
you should disable the entry function.
●Users of any electrical medical device ot her than implantable cardiac pacemakers,
cardiac resynchronization th erapy-pacemakers or implantable cardioverter defibril-
lators should consult the manufacturer of the device for information about its opera-
