1-7. Safety information
RX350/270_EE
■When installing the 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 system, sit the child on a rear seat and
use the vehicle's seat belt. (→P. 8 9 )
CAUTION
■Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly
secure the infant or child. It may result in death or serious injury (in the event of sud-
den 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 wind-
shield, or between you and the vehicle's interior. This may cause death or serious
injury to the child in the event of a sudden stop or an accident.
●Lexus strongly urges the use of a proper child 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 the rear seat than in the front seat.
When you have to use a child restraint system
in the front passenger seat, adjust the seat-
back to the most upright position and adjust
the seat to the fully rearward and uppermost
position.

RX350/270_EE
CAUTION
■Child restraint precautions
●Never use a rear-facing child restraint system on the front passenger seat when
the airbag manual on-off switch is on. (→P. 1 6 3 )
In the event of an accident, the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child.
●A forward-facing child restraint system may be allowed to be installed 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. Adjust the seat-
back as upright as possible and always move the seat as far back as possible
because the front passenger airbag could inflate with considerable 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 deploy even if the child is seated in
the child restraint system. It is dangerous if the side airbags and curtain shield air-
bags 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 injury to the child in the event of a
sudden stop, sudden swerve or an 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 other 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 secured 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 restraint system, remove it from the vehicle or
store it securely in the luggage compartment. This will prevent it from injuring
passengers in the event of a sudden stop, sudden swerve or an accident.
