Be sure to wear the seat belt without the seat belt
extender if you can fasten the seat belt without the
extender.
 Do not use the seat belt extender when installing a
child restraint system on the front or rear passenger
seat. If installing a child restraint system with the seat
belt extender connected to the seat belt, the seat belt
will not securely hold the child restraint system,
which could cause death or serious injury to the child
or other passengers in the event of collision.
SV16050
To connect the extender to the seat belt, insert the tab into
the seat belt buckle so that the ªPRESSº 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 ext ender, not on the seat belt. This helps prevent
damage to the vehicle interior and extender itself.
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.
Seat belt pretensioners
SV16151
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the sensor detects a severe frontal impact, the front seat
belts are quickly drawn back by the retractors so that the belts
snugly restrain the front seat occupants.
The seat belt pretensioners are activated even with no
passenger in the front seats.
The seat belt pretensioners and SRS airbags may not operate
together in all collisions.

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 seat
is the safest for infants and children. For instructions
concerning the installation of a child restraint
system, see ªChild restraintº on page 141.The SRS front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.
The SRS front airbags will deploy if the severity of the impact
is above the designed threshold level, comparable to an
approximate 25 km/h (15 mph) collision when the vehicle has
the impact straight into a fixed barrier that does not move or
deform.
However, this threshold velocity will be considerably higher if
the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform on impact, or if the vehicle is
involved in an underride collision (e.g. a collision in which the
front of the vehicle ªunderridesº, or goes under, the bed of a
truck, etc.).
It is possible that in some collisions where the forward
deceleration of the vehicle is very close to the designed
threshold level, the SRS front airbags and the seat belt
pretensioners may not activate together.
Always wear your seat belts properly.

Lexus strongly recommends that all infants and
children be placed in the rear seat of the vehicle and
be properly restrained.
 Do not allow a child to stand up or kneel on the front
passenger seat, since the front passenger airbag
could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously
injured.
 Do not hold a child on your lap or in your arms. Use
a child restraint system in the rear seat. For
instructions concerning the installation of a child
restraint system, see ªChild restraintº on page 141.
SV16174
Do not put anything or any part of your body on or in
front of the dashboard or steering wheel pad that
houses the front airbag system. They might restrict
inflation or cause death or serious injury as they are
projected rearward by the force of the deploying
airbags. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.

SRS SIDE AIRBAGS AND CURTAINSHIELD AIRBAGS
SV16177
The SRS (Supplemental Restraint System) side airbags
and curtain shield airbags are designed to provide further
protection for the driver and front passenger in addition
to the primary safety protection provided by the seat belts.
In response to a severe side impact, the SRS side airbags and
curtain shield airbags work with the seat belts to help reduce
injury by inflating. The SRS side airbags help reduce injuries
mainly to the driver's or front passenger's chest and the SRS
curtain shield airbags help reduce injuries mainly to the driver's
or front passenger's head.
The SRS side airbag and curtain shield airbag on the
passenger side are activated even with no passenger in the
front seat.
Always wear your seat belt properly.
CAUTION
 The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver and front passenger seat belt
systems. To ensure maximum protection in an
accident, the driver and all passengers in the veh icle
must wear their seat belts properly. Wearing a seat
belt pro perly during an accident reduces the chances
of death or serious injury or being thrown out of the
vehicle. For instructions and precautions
concerning the seat belt system, see ªSeat beltsº on
page 110.
 Do not allow anyone to lean his/her head or any part
of his/her body against the door or the area of the
seat, front pillar, side pillar or roof side rail from
which the SRS side airbag and curtain shield airbag
deploy even if he/she is a child seated in the child
restraint system. It is dangerous if the SRS side
airbag and curtain shield airbag inflate, and the
impact of the deploying airbags could cause death or
serious injury to the occupant.

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 seats
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 ªChild restraintº on page 141.

1Collision from the side to the vehicle body other
than the passenger compartment
2Collision from the side at an angle
The SRS side airbag and curtain shield airbag system may
not activate if the vehicle is subjected to a collision from
the side at certain angles, or a collision to the side of the
vehicle body other than the passenger compartment as
shown in the illustration.
The SRS side airbags and curtain shield airbags are designed
to inflate when the passenger compartment area suffers a
severe impact from the side.
Always wear your seat belts properly.

136When the airbags inflate, they produce a fairly loud noise and
release some smoke and residue along with non±toxic gas.
This
does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death or
serious injury when they inflate, the driver and front
passenger must:
 Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.
SV16025
Do not allow anyone to lean against the front door
when the vehicle is in use. When the side and curtain
shield airbag could inflate with considerable speed
and force. Otherwise, he/she may be killed or
seriously injured. Special care should be taken
especially when you have a small child in the vehicle.
 Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag, and to the front pillar, side pillar and roof
side rail with a curtain shield airbag.

Do not allow anyone to get his/her head closer to the
area where the side airbag and curtain shield airbag
inflate, since these airbags could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.
 Do not allow anyone to kneel on the passenger seat,
facing the passenger's side door, since the side
airbag and curtain shield airbag could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.
SV16175
Do not attach a cup holder or any other device or
object on or around the door. When the side airbag
inflates, the cup holder or any other device or object
will be thrown with great force, or the side airbag may
not activate correctly, resulting in death or serious
injury. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.
