After the rear center seat belt has been used
Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt. (P. 6 1 )
When the child becomes large enough to properly wear the vehicle’s seat belt,
follow the instructions regarding seat belt usage. (P. 38)
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for
the first collision, but will not activate for the second or subsequent collisions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional for seat belt replacement or installation. Stow the buckle as shown.

CAUTION
Observe the following precautions to reduce the risk of injury in the event of sud-
den braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
Wearing a seat belt
Ensure that all passengers wear a seat belt.
Always wear a seat belt properly.
Each seat belt should be used by one person only. Do not use a seat belt for
more than one person at once, including children.
Lexus recommends that children be seated in the rear seat and always use a
seat belt and/or an appropriate child restraint system.
To achieve a proper seating position, do not recline the seat more than neces-
sary. The seat belt is most effective when the occupants are sitting up straight
and well back in the seats.
Do not wear the shoulder belt under your arm.
Always wear your seat belt low and snug across your hips.
Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (P. 38)
Women who are pregnant should position
the lap belt as low as possible over the hips
in the same manner as other occupants,
extending the shoulder belt completely
over the shoulder and avoiding belt contact
with the rounding of the abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury as
a result of sudden braking or a collision.

CAUTION
People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 38)
When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to
cut the belt.
Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that
case, the seat belt cannot be used again and must be replaced at any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
Adjustable shoulder anchor
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 death or serious injuries in the event of a sudden stop, sudden swerve
or accident. (P. 3 9 )
Seat belt damage and wear
Do not damage the seat belts by allowing the belt, plate, or buckle to be
jammed in the door.
Inspect the seat belt system periodically. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt until it is replaced. Damaged seat belts
cannot protect an occupant from death or serious injury.
Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
Replace the seat assembly, including the belts, if your vehicle has been
involved in a serious accident, even if there is no obvious damage.
Do not attempt to install, remove, modify, disassemble or dispose of the seat
belts. Have any necessary repairs carried out by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional. Inappropriate
handling may lead to incorrect operation.

The main SRS airbag system and Pop Up Hood components are shown
above. The SRS airbag system and Pop Up Hood are controlled by the
airbag sensor assembly. As the airbags deploy, a chemical reaction in the
inflators quickly fills the airbags with non-toxic gas to help restrain the
motion of the occupants. When the Pop Up Hood is activated, a non-toxic
gas is released due to a chemical reaction in the lifters, which causes the
pistons to eject quickly and raise the rear portion of the hood. (Pop Up
Hood: P. 56)

CAUTION
SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
The driver and all passengers in the vehicle must wear their seat belts prop-
erly.
The SRS airbags are supplemental devices to be used with the seat belts.
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.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 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 above, while still maintaining
control of the foot pedals, steering wheel, and your view of the instrument
panel controls.

CAUTION
SRS airbag precautions
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 possi-
ble with the seatback adjusted, so the front passenger sits upright.
Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. 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 safer for infants and
children than the front passenger seat. (P. 61)
Do not sit on the edge of the seat or lean
against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or sit
on the knees of a front passenger.
Do not allow the front seat occupants to
hold items on their knees.
Do not lean against the door, the roof side
rail or the front, side and rear pillars.

If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying (inflat-
ing) SRS airbag.
A loud noise and white powder will be emitted.
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, and roof side rails, may
be hot for several minutes. The airbag itself may also be hot.
The windshield may crack.
SRS airbag deployment conditions (SRS front airbags)
The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to an approximately 20 - 30
km/h [12 - 18 mph] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which
can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck
Depending on the type of collision, it is possible that only the seat belt preten-
sioners will activate.
SRS airbag deployment conditions (SRS side and curtain shield airbags)
The SRS side and curtain shield airbags will deploy in the event of an impact
that exceeds the set threshold level (the level of force corresponding to the
impact force produced by an approximately 1500 kg [3300 lb.] vehicle collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orienta-
tion at an approximate speed of 20 - 30 km/h [12 - 18 mph]).
The SRS curtain shield airbags may also deploy in the event of a severe frontal
collision.

It is recommended that children sit in the rear seats to avoid accidental
contact with the shift lever, wiper switch etc.
Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the power
window accidentally.
Do not let small children operate equipment which may catch or pinch
body parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt.
CAUTION
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There
is also a danger that children may injure themselves by playing with the win-
dows, the moon roof or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures inside the vehicle can be fatal to children.
