CAUTION
Observe the following precautions to reduce the risk of injury in the event of sudden
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 necessary. 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. 3 8 )
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. 3 8 )
■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 othe r 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 ne ck, 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 authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●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 pr ofessional. Inappropriate handling may lead
to incorrect operation.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They work
together with the seat belts to help reduce the risk of death or serious injury.

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 chemi-
cal reaction in the lifters, which causes the pistons to eject quickly and raise the
rear portion of the hood. (Pop Up Hood: →P. 5 6 )

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 properly.
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 seri-
ous 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 com-
fortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 250 mm (10 in.) dis-
tance, even with the driver seat all the wa y 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 recommend ed above, while still maintaining control
of the foot pedals, steering wheel, and yo ur 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 possible with the seatback
adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seriously
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 recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear seats are safer for infants and children than the front
passenger seat. ( →P. 6 0 )
●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.

CAUTION
■SRS airbag precautions
●Do not hang coat hangers or hard objects on the coat hooks. All of these items could
become projectiles and may cause death or serious injury, should the SRS curtain
shield airbags deploy.
●If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags inflate
as they may interfere with inflation of the airbags. Such accessories may prevent the
side airbags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.
●Do not allow anyone to kneel on the passen-
ger seats toward the door or put their head or
hands outside the vehicle.
●Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower portion of the instru-
ment panel.
These items can become projectiles when the
SRS driver, front passenger and knee airbags
deploy.
●Do not attach anything to areas such as a door,
windshield glass, side door glass, front or rear
pillar, roof side rail and assist grip. (Except for
the speed limit sticker →P. 5 4 8 )

CAUTION
■SRS airbag precautions
●Do not strike or apply significant levels of force to the area of the SRS airbag compo-
nents.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes are damaged or cracked, have them replaced by any
authorized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional. The SRS airbags may malfunction or deploy (inflate) acciden-
tally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replace ment of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, fr ont, side and rear pillars or roof side rails
●Repairs or modifications of the front fender, front bumper, or side of the occupant
compartment
●Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows, winches
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios (RF-transmitter) and
CD players
●Modifications to your vehicle for a person with a physical disability
