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 access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left 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-butto n start has not been used for 5 days or
longer.
●If the smart access system with push-butto n start has not been used for 14 days or
longer, the doors cannot be unlocked at any doors except the driver’s door. In this case,
take hold of the driver’s door handle, or us e the wireless remote control or the mechan-
ical key, to unlock the doors.
■Conditions affe cting operation
The smart access system with push-button start uses weak radio waves. In the following
situations, the communication between th e electronic key and the vehicle may be
affected, preventing the smart access system with push-button start, wireless remote
control and engine immobilizer system from operating properly.
(Ways of coping: P. 5 4 9 )
●When the electronic key battery is depleted
●Near a TV tower, electric powe r 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 ph one, cordless phone or other wireless com-
munication device
●When the electronic key is in contact wi th, 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
●When carrying 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 me tallic objects are attached to the rear win-
dow

■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 near the ground or in a high place, or too close to the rear
bumper center when the glass hatch is opened.
• 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 and the doors will become lockable from the
outside, possibly trapping the el ectronic key inside the vehicle.
●As long as the electronic key is within the 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 amou nt 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 after approximately 60 seconds if the doors
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 door may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock sensor while wearing gloves may prevent lock operation.
●If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. Plac e 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.)
●If the electronic key is insi de the vehicle and a door handle becomes wet during a car
wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. 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.
●Fingernails may scrape against the door during operation of the door handle.
Be careful not to injure fingernails or damage the surface of the door.
●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.
●Unlocking the vehicle may take more time if another electronic key is within the effec-
tive range.

CAUTION
■Caution regarding interference with electronic devices
●People with implantable cardiac pacemakers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter de fibrillators should keep away from the
smart access system antennas. ( P. 111)
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 other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the ma nufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effe cts on the operation of such medical
devices.
Ask your Lexus dealer for details on disabling the entry function.

Operation of each component
■Active head restraints
Even small forces applied to the seatback may cause the head restraint to move. Pushing
up a locked head restraint forcibly may appear the head restraint inner structure. These
do not indicate problems.
CAUTION
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the se at mechanism.
■Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not recline the seat
more than necessary.
If the seat is too rec lined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
