■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 )
When you have to use a child restraint system
on the front passenger seat, adjust the following:
●The seatback to the most upright position
●The seat cushion to the highest position
●The seat cushion to the fully rearward position
CAUTION
■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).

CAUTION
■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. This may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or accident.
●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 4 )
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 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 seatback 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 fo rce. 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, center and rear pillars or roof side rails from which
the SRS side airbags or SRS curtain shield ai rbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield air-
bags inflate, and the impact could caus e 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.

CAUTION
■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 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. This will prev ent it from injuring passengers in the event
of a sudden stop, sudden swerve or accident.

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 swerv-
ing 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 vehicles).
●Adjust the front passenge r 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 possible.
Failure to do so may result in death or serious
injury if the airbags deploy (inflate).
