■When installing a child restraint system on the front passenger seat
■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes large
enough to properly wear the vehicle’s seat belt.
●If the child is too large for a child restraint sy stem, sit the child on a rear seat and use the
vehicle’s seat belt. ( →P. 3 8 )

■Using a child restraint system
The use of a child restraint system not suit able for the vehicle may not properly secure
the infant or child. It may result in death or serious injury (in the event of sudden braking
or an accident).

■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system depending on the age
and size of the child. Holding a child in your arms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield, or between
you and the vehicle’s interior.
●Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
size of the child, installed on the rear seat. According to accident statistics, the child is
safer when properly restrained in th e rear seat than in the front seat.
●Never use a rear-facing child restraint system on the front passenger seat when the
airbag manual on-off switch is on. (→P. 5 3 )
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child.
●A forward-facing child restraint system may be installed on the front passenger seat
only when it is unavoidable. A child restra int system that requires a top strap should
not be used in the front passenger seat since there is no top strap anchor for the front
passenger seat. Adjust the seatback as upright as possible and always move the seat
as far back as possible because the front passenger airbag could inflate with consid-
erable speed and force. Otherwise, the child may be killed or seriously injured.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front and rear pillars or roof side rails from which the SRS
side airbags or SRS curtain shield airbags depl oy even if the child is seated in the child
restraint system. It is dangerous if the SR S side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all installation instructions provided by the child
restraint manufacturer and that the system is properly secured. If it is not secured
properly, it may cause death or serious inju ry to the child in the event of a sudden
stop, sudden swerve or accident.
■When children are in the vehicle
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 othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut the
belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the trunk. If a head restraint was removed when installing a child
restraint system, always install the head re straint before driving. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or accident.
