If the moon roof does not operate
automatically
If the moon roof does not operate automatically or jam
protection function does not operate correctly, you should
normalize the moon roof.
To normalize the moon roof, push and hold the slide control
switch toward the front or “TILT” switch on the rear side. The
moon roof will tilt up and down, then slide open and close. After
the slide close operation, release the switch.
Make sure that the moon roof opens and closes automatically.
If the moon roof cannot be operated properly, have it checked
by your Lexus dealer.
CAUTION
To avoid serious personal injury, you must do the
following.
 While the vehicle is moving, always keep the heads,
hands and other parts of the bodies of all occupants
away from the roof opening. Otherwise, they could
be seriously injured if the vehicle stops suddenly or
if the vehicle is involved in an accident.
 Before you close the moon roof, always make sure
there is nobody around the moon roof. You must also
make sure nobody places his or her head, hands and
other parts of the body in the roof opening. If
someone’s neck, head or hands get caught in the
closing roof, it could result in death or serious injury.
When anyone closes the moon roof, first make sure
it is safe to do so.
 Be sure to remove the ignition key when you leave
your vehicle.
 Never leave anyone (particularly a small child) alone
in your vehicle, especially with the ignition key still
inserted. Otherwise, he/she could use the moon roof
switches and get trapped in the roof opening.
Unattended person (particularly a small child) can be
involved in a serious accident.
 Never sit on top of the vehicle around the roof
opening.
 Never try jamming any part of your body to activate
the jam protection function intentionally, as it could
result in a serious injury.
 The jam protection function may not work if
something gets caught just before the moon roof is
fully closed.

OCCUPANT RESTRAINT SYSTEMS
194The “AIRBAG ON” and “AIRBAG OFF” indicator lights will
be illuminated when the ignition switch is in the “ON”
position
and a child or child restraint system is in the front
passenger seat (see tablecondition 2). This indicates
that in the event of a severe frontal or passenger’s side
impact, the front passenger airbag and side airbag on the
front passenger seat are deactivated and will not deploy.
If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely to have occurred:
 The rear passenger lifts the front passenger seat cushion
with their legs.
 Objects are placed under the front passenger seat.
 A front passenger seat seatback is in contact with a rear
seat.
To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not happen.
Make sure the “AIRBAG ON” indicator light is illuminated when
an adult sits in the front passenger seat. If the “AIRBAG OFF”
indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the “AIRBAG OFF” indicator light 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 “AIRBAG ON” and “AIRBAG OFF” indicator light will
be initially illuminated when the ignition switch is turned
to the “ON” position. It will remain for about four seconds
and then go off. After about two seconds, the front
passenger occupant classification system operates and
judges whether to turn the indicator light on or not.
The SRS warning light and “AIRBAG OFF” indicator light
will be illuminated if there is a malfunction in the front
passenger occupant classification system.

4. To remove the infant seat, press the buckle release button
and allow the belt to retract completely. The belt will move
freely again and be ready to work for an adult or older child
passenger.(B) Convertible seat installation
A convertible seat must be used in forwardfacing or
rearfacing
position depending on the age and size of the
child. When installing, follow the manufacturer’s
instructions about the appropriate age and size of the
child as well as directions for installing the child restraint
system.
Install 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.
