Fastening front, second and third seat belts
Adjust the seat as needed and sit up straight and well back
in the seat. To fasten your belt, pull it out of the retractor
and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the
seat position.
The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly. A slow,
easy motion will allow the belt to extend, and you can move
around freely. When a passenger’s shoulder belt is completely extended and
is then retracted even slightly, the belt is locked in that position
and cannot be extended. This feature is used to hold the child
restraint system securely.
(For details, see “Child restraint” on
page 175.) To free the belt again, fully retract the belt and then
pull the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly pull
the belt and release it. You will then be able to smoothly pull
the belt out of the retractor.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.

Adjust the position of the lap and shoulder belts.
1Position the lap belt as low as possible on your hips — not
on your waist.
2Adjust it to a snug fit by pulling the shoulder portion
upward through the latch plate.
CAUTION
 Both highpositioned lap belts and loosefitting
belts could cause serious injuries due to sliding
under the lap belt during a collision or other
unintended event. Keep the lap belt positioned as
low on hip as possible.
 Do not place the shoulder belt under your arm.
 Front and second outboard seat belts only
Adjust the shoulder anchor position to your size.
To raise the anchor position, push the anchor up. To lower the
anchor position, support the anchor while you push the lock
release button then slide the anchor down. After the
adjustment, make sure the anchor is locked in position.
CAUTION
Always make sure the shoulder belt is positioned
across the center of your shoulder . The belt should be
kept away from your neck, but not falling off your
shoulder. Failure to do so could reduce the amount of
protection in an accident and cause serious injuries in
a collision.

CAUTION
Do not use the third center seat belt with either buckle
release. Fastening only the shoulder belt or lap belt may
cause severe personal injury in case of sudden braking
or a collision.
STOWING THE THIRD CENTER SEAT BELT
Stow the seat belt tabs into the cover of the roof as shown
above.
Make sure the tabs are securely locked in the cover.

To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the “PRESS” signs on the
buckle release buttons of the extender and the seat belt
are both facing outward as shown.
You will hear a click when the tab locks into the buckle.
When releasing the seat belt, press on the buckle release
button on the extender, not on the seat belt. This helps prevent
damage to the vehicle interior and extender itself.
As far as the seat belt extender on the front passenger side is
concerned, do not fail to disconnect the extender from the seat
belt after the above operation in order to activate the front
passenger airbag correctly when getting into the vehicle next
time.
When not in use, remove the extender and store in the vehicle
for future use.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt and the seat belt extender are not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed, because it cannot
protect an adult occupant or your child from injury.

1Front airbag sensors
2Seat belt pretensioner assemblies
3Front passenger occupant classification system
(ECU and sensors)
4SRS warning light
5Front passenger’s seat belt buckle switch
6Airbag sensor assembly
The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of non −toxic
gas may be released. This does not indicate that a fire is
occurring. This gas is normally harmless. Once
the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.
CAUTION
 Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instruction may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury. Consult your Lexus dealer
about any repair and modification.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury . Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
“Checking and replacing tires” on page 538.

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.

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.
