531-2. Child safety
1
For safety and security
■Removing a child restraint system
installed with a seat belt
Press the buckle release button and
fully retract the seat belt.
When releasing the buckle, the child
restraint system may spring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt automatically reels itself,
slowly return it to the stowing position.
■Child restraint LATCH anchors
LATCH anchors are provided for the
each rear seat. (Buttons displaying the
location of the anchors are attached to
the seats.)
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●Do not allow children to play with the
seat belt. If the seat belt becomes
twisted around a child’s neck, it may
lead to choking or other serious inju-
ries that could result in death. If this
occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.
●Ensure that the belt and plate are
securely locked and the seat belt is not
twisted.
●Shake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.
●After securing a child restraint system,
never adjust the seat.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
■When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( P.26)
■Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.

3-1.Key information
The following keys are provided with
the vehicle.
Electronic keys
• Operating the smart access system with push-button start ( P.103)
• Operating the wireless remote control function
Mechanical keys
Key number plate
Card key (electronic key) (if
equipped)
Operating the smart access system with
push-button start ( P.103)
■Card key (if equipped)
●The card key is not waterproof.
●The mechanical key that is stored inside
the card key should be used only if a
problem arises, such as when the card key does not operate properly.
●If the battery cover is not installed and the
battery falls out or if the battery was
removed because the key got wet, rein-
stall the battery with the positive terminal
facing the Lexus emblem.
■When riding in an aircraft
When bringing an electronic key onto an
aircraft, make sure you do not press any
buttons on the electronic key while inside
the aircraft cabin. If you are carrying an
electronic key in your bag etc., ensure that
the buttons are not likely to be pressed
accidentally. Pressing a button may cause
the electronic key to emit radio waves that
could interfere with the operation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
(The card key battery life is from one year
to one year and a half.)
●If the battery becomes low, an alarm will
sound in the cabin when the engine is
stopped.
●Electronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance. ( P.105)
●As the electronic key always receives
radio waves, the battery will become
depleted even if the electronic key is not
used. The following symptoms indicate
that the electronic key battery may be
depleted. Replace the battery when nec-
essary. ( P.297)
• The smart access system with push-but- ton start or the wireless remote control
does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself

Press twice while pressing and
holding . Confirm that the elec-
tronic key indicator 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,

●Electronic keys that will not be used for
long periods of time can be set to the bat-
tery-saving mode in advance.
■Conditions affe cting operation
The smart access system with push-button
start uses weak radio waves. In the follow-
ing situations, the communication between
the electronic key and the vehicle may be
affected, preventing the smart access sys- tem with push-button start, wireless remote
control and engine immobilizer system
from operating properly.
