Jam protection function
During closing operation, the moon roof stops and is open if
something gets caught into the roof opening.
If the moon roof receives a strong impact, this function may
work even if nothing is caught.
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 a serious injury. When
anyone closes the moon roof, first make sure it is safe
to do so.
 Be sure to remove the ignition key or turn the ignition
switch to the ªLOCKº position 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 (p articularly 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.
 The jam protection function may not work if
something gets caught just before the moon roof
fully closed.

SEATS
While the vehicle is being driven, all vehicle occupants should
have the seatback upright, sit well back in the seat and properly
wear the seat belts provided.
CAUTION
Do not drive the vehicle unless the occupants are
properly seated. Do not allow any passengers to sit
in the luggage compartment or cargo area. Persons
not properly seated and/or not properly restrained by
seat belts can be severely injured in the event of
emergency braking or a collision.
 During driving, do not allow any passengers to stand
up or move around between seats. Otherwise, severe
injuries can occur in the event of emergency braking
or a collision.

Front seat precautions
Driver seat
CAUTION
The SRS driver airbag deploys with considerable force,
and can cause death or serious injury especially if the
driver is very close to the airbag. The National Highway
Traffic Safety Administration (ªNHTSAº) advises:
Since the risk zone for driver airbag is the first 50Ð75
mm (2Ð3 in.) of inflation, placing yourself 250 mm (10
in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the
center of the steering wheel to your breastbone. If you
sit less than 250 mm (10 in.) away now, you can change
your driving position in several ways:
 Move your seat to the rear as far as you can while still
reaching the pedals comfortably.

Slightly recline the back of the seat. Although vehicle
designs vary, many drivers can achieve the 250 mm
(10 in.) distance, even with the driver seat all the way
forward, simply by reclining the back of the seat
somewhat. If reclining the back of your seat makes it
hard to see the road, raise yourself by using a firm,
non±slippery cushion, or raise the seat if your vehicle
has that feature.
 If your steering wheel is adjustable, tilt it downward.
This points the airbag toward your chest instead of
your head and neck.
The seat should be adjusted as recommended by
NHTSA above, while still maintaining control of the foot
pedals, steering wheel, and your view of the instrument
panel controls.
Front passenger seat
CAUTION
The SRS front passenger airbag also deploys with
considerable force, and can cause death or serious
injury especially if the front passenger is very close to
the airbag. The front passenger seat should be as far
from the airbag as possible with the seatback adjusted,
so the front passenger sits upright.
Front seats
CAUTION
The SRS side airbags are installed in the driver and front
passenger seats. Observe the following precautions.
 Do not lean against the front door when the vehicle
is in use, since the side airbag inflates with
considerable speed and force. Otherwise, you may
be killed or severely injured.
 Do not use seat accessories which cover the area
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats equipped with side airbags. Such change
may prevent the side airbag system from activating
correctly, disable the system, or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.

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.

SRS DRIVER AIRBAG AND FRONTPASSENGER AIRBAG
SV16152
The SRS (Supplemental Restraint System) front 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 frontal impact, the SRS front airbags
work together with the seat belts to help reduce injury by
inflating. The SRS front airbags help reduce injuries mainly to
the driver's or front passenger's head or chest caused by
hitting the vehicle interior.
The SRS front passenger airbag is activated even with no
passenger in the front seat.
Always wear your seat belt properly.
CAUTION
The SRS front airbag system is designed only as a
supplement to the primary protection of the driver
and front passenger seat belt systems. The driver
and front passenger can be killed or seriously injured
by the inflating airbags if they do not wear the
available seat belts properly. During sudden braking
just bef ore a collision, an unrestrained driver or front
passenger can move forward into direct contact with
or close proximity to the airbag which may then
deploy during the collision. To ensure maximum
protection in an accident, the driver and all
passengers in the vehicle must wear their seat belts
properly. Wearing a seat belt properly 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.

3SRS warning light
4Airbag sensor assembly
5Front airbag sensors
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensors.
The front airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non±toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver's vision should it be necessary to continue driving. When the airbags inflate, they produce a 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, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant's hands, arms, chest or head is in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to: avoid placing any
object or part of the body bet ween the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, airbag cover
and inflator) may be hot for several minutes after deployment,
so do not touch! The airbags inflate only once. The windshield
may be damaged by absorbing some of the force of the
inflating airbag.

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.
