Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system compon ents diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a
chemical reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the moti on of the occupants.

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 consider able force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) 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 10 in. (250 mm) 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 10 in. (250 mm) 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 ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommen ded by NHTSA above, while still maintain-
ing control of the foot pedals, steering whee l, 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 possible with the seatback
adjusted, so the front passenger sits upright.
●Improperly seated and/or re strained 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 safe r for infants and children than the front
passenger seat. ( P. 5 4 )
●If the seat belt extender has been connected
to the front seat belt buckles but the seat belt
extender has not also been fastened to the
latch plate of the seat belt, the SRS front air-
bags will judge that the driver and front pas-
senger are wearing the seat belt even though
the seat belt has not been connected. In this
case, the SRS front airbags may not activate
correctly in a collision, resulting in death or
serious injury in the event of a collision. Be
sure to wear the seat belt with the seat belt
extender.
●Do not sit on the edge of the seat or lean
against the dashboard.

CAUTION
■SRS airbag precautions
●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.
●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.

Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seats, behind the anchor
covers.
Seat belts equipped with a child
restraint locking mechanism (ALR/
ELR belts except driver’s seat belt)
(P. 3 2 )
Anchor brackets (for top tether strap)
An anchor bracket is provided for each
rear seat.
Installing child restraints
Follow the child restraint system manu facturer’s instructions. Firmly secure
child restraints to the seats using the LATCH anchors or a seat belt. Attach the
top tether strap when installing a child restraint.
The lap/shoulder belt can be used if yo ur child restraint system is not compati-
ble with the LATCH (Lower Anchor s and Tethers for Children) system.

CAUTION
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to
the child. ( P. 3 2 )
■When installing a child restraint system
Follow the directions given in the child restra int system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of a sudden braking or an accident.
●If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, attach the child restraint
system to the right-hand rear seat.
●Adjust the front passenger seat so that it does
not interfere with the child restraint system.
●Only put a forward-facing child restraint sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).
