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
Observe the following precautions.
Failure to do so may result in death or serious injury.
Before driving
Make sure that the trunk lid is fully closed. If the trunk lid is not fully closed,
it may open unexpectedly while driving and hit near-by objects or luggage in
the trunk may be thrown out, causing an accident.
Do not allow children to play in the trunk.
If a child is accidentally locked in the trunk, they could suffer from heat
exhaustion, suffocation or other injuries.
Do not allow a child to open or close the trunk lid.
Doing so may cause the trunk lid to open unexpectedly, or cause the child’s
hands, head, or neck to be caught by the closing trunk lid.
Important points while driving
Never let anyone sit in the trunk. In the event of sudden braking or a collision,
they are susceptible to death or serious injury.
