RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)Your vehicle is equipped with ADVA NCED AIRBAGS designed based on the
US motor vehicle safety standards (F MVSS208). 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 motion of the occupants.SRS airbag system components

SRS airbag precautions
Observe the following precaution s 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 us ed 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. 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 ha rd to see the road,
raise yourself by using a firm , non-slippery cushion, or ra ise the seat if your vehicle
has that feature.
• If your steering wheel is ad justable, tilt it do wnward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA ab ove, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.

SRS airbag precautions
●
The SRS front passenger airbag also deploy s 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 chil d 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 se ats are safer for infants an d children than the front
passenger seat. (  P. 58)●
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.

SRS airbag deployment cond itions (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 wa ll that does not move or deform).
However, this threshold velocity will be cons iderably higher in th e 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 possi ble that only the seat belt pretensioners will
activate. ●
The SRS front airbags for the fr ont 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. (  P. 51)■
SRS airbag deployment conditions (S RS side and curtain shield airbags)●
The SRS side and curtain shield airbags w ill 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. [15 00 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]). ●
The SRS curtain shield airbags will deploy in the event of vehicle rollover. ●
The SRS side and curtain shield airbags will de ploy in the event of a severe frontal colli-
sion. ■
Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags, SRS side and curtain sh ield airbags may also deploy if a serious
impact occurs to the undersid e of your vehicle. Some exampl es are shown in the illustra-
tion.
The SRS curtain shield airbags may also deploy under the situations shown in the illustra-
tion. ●
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.

There is a malfunction in the system
* 1
: The system judges a person of adult size as an adult. When a smaller adult sits in
the front passenger seat, the system ma y not recognize him/her as an adult
depending on his/her physique and posture.
* 2
: In the event the front passenger is wearing a seat belt.
* 3
: In the event the front passenger does not wear a seat belt
* 4
: For some children, child in seat, child in booster seat or child in convertible seat,
the system may not recognize him/her as a child. Factors which may affect this can
be the physique or posture.
* 5
: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint sy stem should only be inst alled on the front passenger
seat when it is unavoidable. (  P. 58)
* 6
: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. (  P. 60)Indicator/
