SRS airbags
◆SRS front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front passenger from
impact with interior components
SRS knee airbags
Can help provide driver and front passenger protection
An SRS knee airbag for the front passenger’s seat is built into the glove box door.
◆SRS side and curtain shield airbags
SRS front side airbags
Can help protect the torso of the front seat occupants
SRS rear side airbags
Can help protect the torso of oc cupants in the rear outer seats
SRS curtain shield airbags
Can help protect primarily the head of occupants in the outer seats
The SRS airbags inflate when the vehi cle is subjected to certain types of
severe impacts that may cause significan t injury to the occupants. They work
together with the seat belts to help re duce the risk of death or serious injury.

The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.
WARNING
■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 driv er 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 o f 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:

WARNING
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can cause
death or serious injury especially if the fron t 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 infant s 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. 64)
●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.

WARNING
■SRS airbag precautions
●Do not hang coat hangers or other hard obje cts on the coat hooks. All of these items
could become projectiles and may cause deat h 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 th e 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 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, lower portion of the instrument
panel and door of the glove box.
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. 581)

■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, the glove box, 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.
●Vehicles with ERA-GLONASS: If the SRS ai rbags deploy, the system is designed to
send an emergency call * to the Public Safety Answer ing Point (PSAP), 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 assistance
required. If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to di spatch the necessary emergency services.
(  P. 435)
* : In some cases, the call cannot be made. ( P. 437)
■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 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 cons iderably higher in the following situations:

The SRS side and curtain shield airbags do not generally inflate if the vehicle is involved in
a rear collision, if it rolls over, or if it is involved in a low-speed side or low-speed frontal
collision.
■When to contact any authorized Lexus reta iler or Lexus authorized repairer, or any
reliable repairer
In the following cases, the vehicle will requ ire inspection and/or repair. Contact any
authorized Lexus retailer or Le xus authorized repairer, or any reliable repairer as soon as
possible.
●Any of the SRS airbags have been inflated.
●Collision from the rear
●Vehicle rollover
●The front of the vehicle is damaged or
deformed, or was involved in an accident that
was not severe enough to cause the SRS front
airbags to inflate.
●A portion of a door or it’s surrounding area is
damaged or deformed, or the vehicle was
involved in an accident that was not severe
enough to cause the SRS side and curtain
shield airbags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag, lower
portion of the instrument panel or door of the
glove box is scratched, cracked, or otherwise
damaged.

Safety information for children
● 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 drivin g or operating the power window acci-
dentally. ( P. 163, 214)
● Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
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 vehicl e, and never allow children to have or use
the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
(if equipped) or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.
