CAUTION
When installing a child restraint system
Follow the directions given in the child restraint system installation manual and
fix the child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other
passengers may be seriously injured or even killed in the event of a sudden
braking, sudden swerving or an accident.
If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach the
child restraint system to the right-hand
rear seat (left-hand drive vehicles) or the
left-hand rear seat (right-hand drive vehi-
cles).
Adjust the front passenger seat so that it
does not interfere with the child restraint
system.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as possi-
ble.
Failure to do so may result in death or
serious injury if the airbags deploy
(inflate).

serious injury to children in the event of
an accident.
There is a label(s) on the passenger side
sun visor, indicating it is forbidden to
attach a rear-facing child restraint system

CAUTION
When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional for the child restraint system installation.
When a junior seat is installed, always ensure that the shoulder belt is posi-
tioned 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. Fail-
ing to do so may result in death or serious injury in the event of sudden brak-
ing, sudden swerving or an accident.
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.
Follow all installation instructions provided by the child restraint system
manufacturer.
To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint system.
Make sure the child restraint system is securely attached, or it may cause death
or serious injury to the child or other passengers in the event of a sudden brak-
ing, sudden swerve or an accident.

CAUTION
When closing the windows or moon roof using wireless remote control
Observe the following precautions.
Failing to do so may result in death or serious injury.
Check to make sure that all passengers do not have any part of their body in a
position where it could be caught when a window or moon roof is being oper-
ated.
To prevent inadvertent power windows and moon roof operation, never let a
small child have and use the wireless remote control.
Jam protection function
Never try jamming any part of your body to activate the jam protection func-
tion intentionally.
The jam protection function may not work if something gets caught just
before the window or moon roof fully closes.
