CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are safer for infants and children than the
front passenger seat. (→P. 1 4 2 )
●Do not sit on the edge of the seat or lean
against the dashboard.
●Do not allow a child to stand in front of the
SRS front passenger airbag unit or sit on
the knees of a front passenger.
●Do not allow the front seat occupants to
hold items on their knees.

Child restraint systems
Points to remember
Studies have shown that installing a child restraint on a rear seat is much
safer than installing one to the front passenger seat.
●Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
●For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (→P. 1 5 2 )
●If child restraint system regulations exist in the country where you
reside, please contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for the child restraint
system installation.
●Lexus recommends that you use a child restraint system which con-
forms to the regulation ECE No.44.

If the head restraint interferes with your child restraint system, and the head
restraint can be removed, remove the head restraint.
If the passenger seat is equipped with a vertical height adjuster, it must be
placed in the uppermost position.
Follow these procedures:
• For installing a baby seat with support base
If the baby seat interferes with the seatback when latching the baby seat
into the support base, adjust the seatback rearward until there is no inter-
ference.
• For installing a forward-facing child seat
If there is gap between the child seat and the seatback, tilt the seatback
rearward until good contact is achieved.
If the seat belt shoulder anchor is ahead of the child seat belt guide, move
the seat cushion forward.
• For installing a junior seat
If the child in your child restraint system is in a very upright position, adjust
the seatback to the most comfortable position.
If the seat belt shoulder anchor is ahead of the child seat belt guide, move
the seat cushion forward.

2: If the head restraint interferes with your child restraint system, and the head
restraint can be removed, remove the head restraint.

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.
