CAUTION
■Front passenger occupant classification system precautions
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear seat, return the seatback to a position where it does
not touch the rear seat. Keep the front passenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still remains illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. (→P. 1 1 8 )
●Do not modify or remove the front seats.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the rear seat should not contact the front seat-
backs.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.

Child restraint systems
Points to rememberStudies have shown that installing a child restraint on a rear seat is 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 1 8 )
Types of child restraints
Child restraint systems are classified into the following 3 types according
to the age and size of the child. Rear facing  Infant seat/convertible seat
A child restraint system for a small child or baby must itself be properly
restrained on the seat with the lap portion of the lap/shoulder belt.
The laws of all 50 states of the U. S.A. and Canada now require the use of
child restraint systems.

■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 a child is too large for a child restraint system, sit the child on a rear seat and
use the vehicle's seat belt. ( →P. 6 5 )
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 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.

CAUTION
■Child restraint precautions
●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.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
●A forward-facing child restraint system may 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 seatback as upright as possi-
ble and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of a sudden stop, sudden swerve or collision.
●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 pillar, rear pillar or roof side rail from which the
side airbags or 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 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 injury to the child in the event of a
sudden stop, sudden swerve or an 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 secured on the seat even if it is not in use.
Do not store the restraint 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 trunk. This will prevent it from injuring passengers in the
event of a sudden stop, sudden swerve or an accident.

Before driving
IS350/250_UWhile pushing the child seat into
the rear seat, allow the shoulder
belt to retract until the child seat is
securely in place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.

should be latched onto the top tether strap anchors.
■ Booster seat
Place the booster seat on the seat
facing the front of the vehicle.
Sit the child in the booster seat. Fit
the seat belt to the booster seat
according to the manufacturer's
instructions and insert the plate
into the buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child's
shoulder, and that the lap belt is as
low as possible. (→
