●When carrying the electronic key together with the following devices that emit radio
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

■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.

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.)

■Caution regarding interference with electronic devices
●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-
tion 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 on disabling the entry function.
