WARNING
■
SRS airbag precautions
●
Do not hang coat hangers or other hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the SRS cur-
tain 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 SRS 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 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 seat 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.

WARNING
■
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 your
Lexus dealer.
●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, the SRS front airbags for the front passenger
may not deploy in the event of a collision.
■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airbags may malfunction or deploy (inflate)
accidentally, causing death or serious injury.
●
Installation, removal, disassembly and repair of the SRS airbags
●
Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, 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 or
roof luggage carrier
●
Modifications to the vehicle’s suspension system
●
Installation of electronic devices such as mobile two-way radios and CD players
●
Modifications to your vehicle for a person with a physical disability

■
If the SRS airbags deploy (inflate)
●
Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) by hot gases.
●
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
seats, parts of the front and rear pillars, and roof side rails may be hot for several min-
utes. The airbag itself may also be hot.
●
The windshield may crack.
●
All of the doors will be unlocked. (
●
Fuel supply to the engine will be stopped. (
●
For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
the system is designed to send an emergency call to the response center, notifying
them of the vehicle’s location (without needing to push the “SOS” button) and an agent
will attempt to speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency ser-
vices. (
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■
SRS airbag deployment conditions (SRS front airbags)
●
The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old level (the level of force corresponding to an approximately 12 - 18 mph [20 - 30
km/h] 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 pretensioners will
activate.
●
The SRS front airbags for the front passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the seat is unoccupied. (
■
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 3300 lb. [1500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 - 18 mph [20 - 30 km/h]).
●
Both SRS curtain shield airbags will deploy in the event of vehicle rollover.
●
Both SRS curtain shield airbags will deploy in the event of a severe frontal collision.

■
Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS curtain shield airbags may also deploy if a serious impact
occurs to the underside of your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the illustra-
tion.
■
Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not generally inflate if the vehicle is involved in a side or rear
collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forward deceleration of the vehicle, deployment of
the SRS front airbags may occur.
●
Hitting a curb, edge of pavement or hard sur-
face
●
Falling into or jumping over a deep hole
●
Landing hard or falling
●
The angle of vehicle tip-up is marginal.
●
The vehicle skids and hits a curb stone.
●
Collision from the side
●
Collision from the rear
●

Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield air-
bags)
The SRS side and curtain shield airbags 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.
The SRS side airbags do not generally inflate if the vehicle is involved in a frontal or rear
collision, if it rolls over, or if it is involved in a low-speed side collision.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear
collision, if it pitches end over end, or if it is involved in a low-speed side or low-speed
frontal collision.

WARNING
■
Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury.
●
Wear the seat belt properly.
●
Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
●
Make sure the “AIR BAG OFF” indicator light is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON”
indicator light is illuminated. If you use the seat belt extender while the “AIR BAG
OFF” indicator light is illuminated, the SRS airbags for the front passenger may not
activate, which could cause death or serious injury in the event of a collision.
●
Do not apply a heavy load to the front passenger seat or equipment (e.g. seatback
pocket).
●
Do not put weight on the front passenger seat by putting your hands or feet on the
front passenger seat seatback from the rear passenger seat.
●
Do not let a rear passenger lift the front passenger seat with their feet or press on the
seatback with their legs.
●
Do not put objects under the front passenger seat.

WARNING
■
Front passenger occupant classification system precautions
●
Do not recline the front passenger seatback so far that it touches the rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that
the SRS airbags for the front passenger will not deploy in the event of a severe acci-
dent. If the seatback touches the rear seat, return the seatback to a position where it
does not touch the rear seat. Keep the front passenger seatback as upright as possi-
ble when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
●
If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit up
straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If
the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward.
●
When it is unavoidable to install a forward-facing child restraint system on the front
passenger seat, install the child restraint system on the front passenger seat in the
proper order. (
●
Do not modify or remove the front seats.
●
Do not kick the front passenger seat or subject it to severe impact. Otherwise, the
SRS warning light may come on to indicate a malfunction of the front passenger
occupant classification system. In this case, contact your Lexus dealer immediately.
●
Child restraint systems installed on the rear seat should not contact the front seat-
backs.
●
Do not use a seat accessory, such as a cushion and seat cover, that covers the seat
cushion surface.
●
Do not modify or replace the upholstery of the front seat.
●
Do not place anything between the console box and front passenger seat. Other-
wise, the system may not detect the front passenger properly, leading to improper
operation of the airbags.
●
Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.
52

IS350 AWD/IS350/IS300 AWD/IS300_U
●
It is recommended that children sit in the rear seats to avoid accidental con-
tact 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 acci-
dentally.
●
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.
WARNING
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 windows, the moon roof
or other features of the vehicle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

Studies have shown that installing a child restraint on a rear seat is much safer
than installing one on the front passenger seat.
●
Choose a child restraint system that suits your vehicle and is appropriate to
the age and size of the child.
●
For installation details, follow the instructions provided with the child restraint
system.
General installation instructions are provided in this manual. (
Child restraint systems
A child restraint system for a small child or baby must itself be properly
restrained on the seat with the LATCH anchors or the lap portion of the lap/
shoulder belt.
The laws of all 50 states of the U.S.A. and Canada now require the use of child
restraint systems.
Points to remember
54
1-1. For safe use
IS350 AWD/IS350/IS300 AWD/IS300_U
Child restraint systems are classified into the following 3 types according to the
age and size of the child:
■
Selecting an appropriate child restraint system
●
Use a child restraint system appropriate for the child until the child becomes large
enough to properly wear the vehicle’s seat belt.
●
If the child is too large for a child restraint system, sit the child on a rear seat and use the
vehicle’s seat belt. (

WARNING
■
Child restraint precautions
●
For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system depending on the age
and size of the child. Holding a child in your arms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield, or between
you and the vehicle’s interior. This may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or an accident.
●
Lexus strongly urges the use of a proper child restraint system that conforms to the
size of the child, installed on the rear seat. According to accident statistics, the child is
safer when properly restrained in the rear seat than in the front seat.
●
Never install a rear-facing child restraint system on the front passenger seat even if
the “AIR BAG OFF” indicator light is illuminated.
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child if the rear-facing child restraint sys-
tem is installed on the front passenger seat.
●
A forward-facing child restraint system may be installed on the front passenger seat
only when it is unavoidable. A child restraint system that requires a top tether strap
should not be used in the front passenger seat since there is no top tether strap
anchor for the front passenger seat. Adjust the seatback as upright as possible and
always move the seat as far back as possible even if the “AIR BAG OFF” indicator
light is illuminated, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.
●
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 sys-
tem, which could cause death or serious injury to the child or other passengers in the
event of a sudden stop, sudden swerve or accident.
●
Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front, center and rear pillars or roof side rails from which
the SRS side airbags or SRS curtain shield airbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield air-
bags inflate, and the impact could cause death or serious injury to the child.
●
Make sure you have complied with all installation instructions provided by the child
restraint manufacturer and that the system is properly secured. If it is not secured
properly, it may cause death or serious injury to the child in the event of a sudden
stop, sudden swerve or an accident.
