When a child is riding
Observe the following precautions.
Failure to do so may result in death or serious injury.●
For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint syst em which is correctly
installed. For installation details, refer to the operation manual enclosed with the child
restraint system. General in stallation instruction is provided in this manual.●
Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
weight and size of the child, installed on the rear seat. According to accident statistics,
the child is safer when proper ly restrained in the rear se at than in the front seat.●
Holding a child in your or someone else’s ar ms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between
the holder and the interior of the vehicle. ■
Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerv-
ing, or an accident. ●
If the vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has da mage that is not readily visible. In such cases, do not
reuse the restraint system. ●
Make sure you have complied with all installa tion instructions prov ided with the child
restraint system manufacturer and th at the system is properly secured.●

Observe the following precautions.
Failure to do so may result in death or serious injury.●
Never install a rear-facing ch ild restraint system on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the even t of an accident, the force
of the rapid inflation of the front passenger airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is inst alled on the front passenger
seat. ●

only when it is unavoidable. A child restraint system that requires a top tether strap
should not be used in the front passenger seat since there is no top tether strap
anchor for the front passenger seat.

head restraint can be removed, remove the head restraint.
If the head restraint cannot be remove d, raise it to the uppermost position.
●
When a booster seat is installed, always en sure that the 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 coul d fall off the child’s shoulder.●

rear seat. ●
A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restrain t system on the front
passenger seat, raise the seatback as much as
possible, move the seat to the rearmost posi-
tion, and raise the seat to the highest position,
even if the “AIR BAG OFF” indicator light is
illuminated. ●

any part of his/her body against the door or
the area of the seat, front or rear pillars, or
roof side rails from which the SRS side air-
bags or SRS curtain shield airbags deploy
even if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.
●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat. ●
