CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, im pair judgment and reduce coordination,
which could lead to an accident that will hurt or kill you, your occupants or others.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full at tention to driving. Anything that distracts
the driver, such as adjusting controls, ta lking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■General precautions regarding children’s safety
Never leave children unattended in the vehi cle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures insi de the vehicle can be fatal to children.
■Dispose of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery having been removed, there
is a danger of serious electric shock if high voltage parts, cables and their connec-
tors are touched. In the event of that your vehicle must be disposed of, the hybrid
battery must be disposed of your Lexus dealer or a qualified service shop. If the
hybrid battery is not disposed of properly, they may cause electric shock that can
result in death or serious injury.

■Operation signals
●Doors: A buzzer sounds and the emergency flashers flash to indicate that the
doors have been locked/unlocked. (Locked: Once; Unlocked: Twice)
●Windows and moon roof: A buzzer sounds when the windows and moon roof
begin to close.
■Door lock buzzer
If a door is not fully closed, a buzzer sounds continuously if an attempt to lock the
door is made. Fully close the door to stop the buzzer, and lock the vehicle once
more.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between key and vehicle may be affected,
preventing the smart access system with push-button start and wireless remote
control from operating properly. (Way of coping: P. 5 3 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 has come into contact with, or is covered by a metallic
object
●When multiple electronic keys are in the vicinity
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle’s electronic key
• A wireless key that emits radio waves
• Personal computer
●If window tint with a metallic content or metallic objects are attached to the rear

■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 cond ition of the electronic key, the key may
not be detected corr ectly 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 hybrid system is started or “POWER” 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 th e vehicle, it may be possible to start the
hybrid system 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.)
