The “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 occur.
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.

170The “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.

ROLL SENSING OF CURTAIN
SHIELD AIRBAGS OFF SWITCH
The roll sensing of curtain shield airbags off switch
(“RSCA OFF” switch) can turn off the curtain shield
airbags and seat belt pretensioners in a vehicle rollover.
This switch should only be used if inflation is not desired
(such as extreme offroad driving).
When you push the “RSCA OFF” switch for a few seconds with
the ignition switch on, the “RSCA 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. (For details about the roll sensing
function, see “SRS side airbags and curtain shield airbags” on
page 156.) In a severe side impact, the curtain shield airbags on impacted
side will inflate even if the roll sensing function is turned off.
(For details about the curtain shield airbags, see “SRS side
airbags and curtain shield airbags” on page 156.)
In a severe frontal impact, the seat belt pretensioners will work
even if the roll sensing function is turned off. (For details about
the seat belt pretensioners, see “Seat belt pretensioners” on
page 142.)
If the ignition switch is turned to “ACC” or “LOCK” with the\
roll
sensing
function off and then the ignition switch is turned back
to “ON”, the roll sensing function will turn back on
automatically.CAUTION
 Before normal driving, make sure the “RSCA OFF”
indicator light is off.
 When the roll sensing function is turned off (and the
“RSCA OFF” indicator light is on), the curtain shield
airbags and seat belt pretensioners will not work in
a vehicle rollover. Turning off the curtain shield
airbags and seat belt pretensioners reduces
occupant protection which your vehicle safety
systems can provide in accidents and increase the
likelihood of death or serious injuries.

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.

5. 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 OFF” indicator light should be illuminated when
the ignition key is “ON” and the child is in the child restraint
system after following these procedures. The “AIRBAG OFF”
indicator light indicates the SRS front passenger airbag and
side airbag on the passenger side will not deploy. If the
“AIRBAG ON” indicator light is illuminated, remove the child
restraint system and reinstall it with the ignition key in the
“ACC” or “LOCK” position. If the “AIRBAG ON” indicator light
still remains illuminated when the ignition key is turned to the
“ON” 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 forwardfacing
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 MEMORYSYSTEM
A microcomputer will memorize the position of the driver’s
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Two dif ferent driving position profiles
can be entered into the computer’s memory.
Recording the driving position in the computer’s memory can
only be done when the ignition key is in the “ON” position and
the selector lever is in the “P” position.
Setting the driving position
1. Adjust the driver’s seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the “SET” button, push button “1” or “2”
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 “1” or “2”, the driving position will
be automatically adjusted to the position recorded for that
button.
