FRONT PASSENGER OCCUPANT
CLASSIFICATION SYSTEM
Your vehicle is equipped with a front passenger occupant
classification system. This system detects the conditions
1 Ð 4 in the table shown below, and based on these
conditions activates or deactivates the airbags. The
system monitors the weight and load on the front
passenger seat, and the seat belt buckle switch in
determining conditions correctly, do not do any of the
following.
Put a heavy load in the seatback pocket.
Attach a seatback table to the front passenger seat
seatback of the front passenger seat.
Put weight on the front passenger by putting your hands or
feet on the front passenger seat seatback from the rear
passenger seat.
The AIRBAG OFFº indicator light will be illuminated
when the ignition switch is in the ONº position and a child
restraint system is in the front passenger seat (see
table-condition 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 an adult sits in the front passenger seat, the AIRBAG OFFº
indicator light may also be illuminated if the following occurs.
A rear passenger lifts the front passenger seat cushion with
their legs.
Objects are placed under the front passenger seat.
The front passenger seat seatback is in contact with the rear
seat.

OCCUPANT RESTRAINT SYSTEM
153 To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make sure the AIRBAG ONº indicator light is illuminated when
an adult is seated in the front passenger seat. If the AIRBAG
OFFº 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 OFFº 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 OFFº and AIRBAG ONº indicator lights will
be initially illuminated when the ignition switch is turned
to the ONº position. It will remain for about four seconds
and then go off. After the two seconds, the front
passenger occupant classification system operates and
judges which indicator light to turn on.
The SRS warning light and AIRBAG OFFº 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 forward-facing or
rear-facing position depending on the age and size of the
child. When installing, follow the manufacturer's
instructions about the applicable child's age and size 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 ONº 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.

1645. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retracted 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 restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided 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 AIRBAG OFFº indicator light should be illuminated when
the ignition key is ONº and the child is in the child restraint
system after following these procedures. The AIRBAG OFFº
indicator light indicates the SRS front passenger airbag and
side airbag on the passenger side will not deploy. If the
AIRBAG ONº indicator light is illuminated, remove the child
restraint system and reinstall it with the ignition key in the
ACCº or LOCKº position. If the AIRBAG OFFº indicator light
still remains illuminated when the ignition key is turned to the
ONº position, then the SRS front passenger airbag and side
airbag on the passenger side may deploy in an accident. Do
not drive the vehicle in this condition. Remove the child
restraint system and contact your Lexus dealer.
CAUTION
When it is unavoidable to install the forward-facing
child restraint system on the front passenger seat,
install the child restraint system on the front
passenger seat in the proper order. Otherwise, the
front passenger occupant classification system can
not detect the presence of the child restraint system
and the front passenger airbag and side airbag on the
front passenger seat could deploy.

DRIVING POSITION MEMORY
SYSTEM
The microcomputer can memorize the positions of the driver's
seat, accelerator and brake pedals, and outside rear view
mirrors. Two different driving position profiles can be entered
into the computer's memory.
Recording a driving position in the computer's memory can
only be done when the ignition key is in the ONº position and
the selector lever is in the Pº position.
Setting the driving position
1. Adjust the driver's seat, accelerator and brake pedals,
and outside rear view mirrors to the desired position.
2. While pushing the SETº button, push button 1º or 2º
until the signal beeps.
The beep sound means that the positions are recorded in the
computer's memory.By repeating these two steps and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
When you push button 1º or 2º, the driving position will
be automatically adjusted to the position recorded for that
button.
