possible:

Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. 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 seat of the vehicle and properly restrained.
The rear seats are the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 162.

 Roll sensing of curtain shield airbags off switch
The roll sensing of curtain shield airbags off switch can
turn off the curtain shield airbags in a vehicle rollover.
This switch should only be used in a situation where the
inflation is not desired (such as during extreme offroad
driving).
When you push the roll sensing of curtain shield airbags off
switch for a few seconds with the ignition switch on, the roll
sensing of curtain shield airbags off indicator light comes on
and the roll sensing function is turned off. When you push the
switch again, the indicator light goes off and the roll sensing
function is turned on.
In a severe side impact, the curtain shield airbag on the
impacted side will inflate even if the roll sensing function is
turned off.
If the ignition switch is turned to “ACC” or “LOCK” with the r\
oll
sensing function off and then the ignition switch is turned back
to “ON”, the roll sensing function will be back on automatically.

If you wish to modify your vehicle for a person with a
physical disability, consult your Lexus dealer. It may
dangerously interfere with the SRS side airbags and
curtain shield airbags operation.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS side airbag
and curtain shield airbag system in some cases.
Installation of electronic devices such as a mobile

The front passenger occupant classification indicator
light indicates the actuation of the front passenger airbag,
side airbag on the front passenger seat and front
passenger’s seat belt pretensioner.
The indicator light will indicate “OFF” when the ignition switch
is in the “ON” position with the condition 2 in the table shown
below.
If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “OFF” indicator is illuminated, one of
the following is likely to have occurred:
 A rear passenger lifts the front passenger seat cushion with
their legs.
 Objects are placed under the front passenger seat.
 The front passenger seatback is in contact with the rear
seat. To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make sure that the “ON” indicator is illuminated when an adult
is seated in the front passenger seat. If the “OFF” indicator is
illuminated, ask the passenger to sit up straight, well back in
the seat, and with the seat belt worn correctly. If the “OFF”
indicator still
remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front
passenger seat fully rearward.
The front passenger occupant classification indicator
light will indicate “ON” and “OFF” when the ignition key
is turned to the “ON” position. After about 4 seconds, it
will go off. After about 2 seconds, the front passenger
occupant classification system operates and judges
whether to indicate “ON” or “OFF”.

OCCUPANT RESTRAINT SYSTEMS
176Install the child restraint system on the front passenger seat
only when it is unavoidable. Your vehicle is equipped with a
front passenger occupant classification system. In order to
activate
the occupant classification system correctly, install the
forward−facing child restraint system on the front passenger
seat in the following order:
1. Turn the ignition key to the “ON” position.
2. Move the front passenger seat to the rearward position.
3. Put the child restraint system on the front passenger seat
without putting your weight on the front passenger seat.
4. Insert the seat belt tab into the seat belt buckle.
5. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retrac ted even slightly, it cannot be
extended. To hold the seat securely, make sure the belt is in the
lock mode before letting the belt retract.
6. While pressing the convertible seat firmly against the seat
cushion and seatback, let the shoulder belt retract as far as it
will go to hold the convertible seat securely.
CAUTION
Push and pull the child r estraint system in different
directions to be sure it is secure. Follow all the
installation instructions pr ovided by its manufacturer.
7. Put a child on the child restraint system and secure the child,
complying with the instructions provided by the child restraint
system manufacturer. The occupant classification indicator light should indicate
“OFF”
when the ignition key is in the “ON” position and the child
is in the child restraint system after following these procedures.
The “OFF” indicator indicates the SRS front passenger airbag
will not deploy. If the indicator light indicates “ON”, remove the
child restraint system and reinstall it with the ignition key in the
“ACC” or “LOCK” position. If the indicator light still indicates
“ON” when the ignition key is turned to the “ON” position, then
the SRS front passenger airbag may deploy in an accident. Do
not drive the vehicle in this condition. Remove the child
restraint system and contact your Lexus dealer.
CAUTION
Never install a rearfacing child restraint system on
the front passenger seat. A forwardfacing child
restraint system should only be installed on the front
passenger seat when unavoidable. If you must install
the child restraint system on the front passenger
seat, put the seat in its mo st rearward position, and
install the forwardfacing child restraint system in
the proper order. Otherw ise, the front passenger
occupant classification system cannot detect the
presence of the child rest raint system and the front
passenger airbag could deploy.
