Front passenger occupant classi fication system precautions●
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 remain illuminated, either ask the pas-
senger to move to the second seat, or if that is not possible, move the front
passenger seat fully rearward. ●
When it is unavoidable to install the forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. ( P. 1 4 9 )●
Do not modify or remove the front seat. ●
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 in the detection sys-
tem. In this case, contact your Lexus dealer immediately. ●
Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface. ●
Child restraint systems installed on the se cond seat should not contact the front
seatbacks.

LX570_OM_OM60L21U_(U) Child restraint systems Points to remember
Studies have shown that installing a ch ild 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 4 9 )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.

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 belts. ●
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. 9 1 ) When you have to use a child restraint system
on the front passenger seat, adjust the follow-
ing: ●
The seatback to the most upright posi-
tion ●
The seat cushion to the fully rearward
and highest position ●
The seat belt height to the lowest posi-
tion

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, resulting in serious injury or even death. ■
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 chil d 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. ●
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 illumina tes. 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 illuminates, because the fr ont 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 accident.
