diagram LEXUS RCF 2021 Owners Manual

301-1. For safe use
shown in the system components 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 no n-toxic gas to help restrain the motion of
the occupants.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) 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 front seat s, 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.
●For Lexus Enform Safety Connect sub-
scribers, if the SRS airbags deploy or in
the event of a severe rear-end collision,
the system is designed to send an emer-
gency call to the response center, notify-
ing them of the vehicl e’s location (without
needing to push the “SOS” button) and
an agent will attempt to speak with the
occupants to ascertain the level of emer-
gency and assistance required. If the
occupants are unable to communicate,
the agent automatically treats the call as
an emergency and helps to dispatch the
necessary emergency services. ( P.53)
■SRS airbag deployment conditions (SRS
front airbags)
●The SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding 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 situa-
tions:
• 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 preten-
sioners will activate.
●The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
■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 per-
pendicular 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 deploy in the event of a severe frontal
collision.
■Conditions under which the SRS air-
bags may deploy (inflate), other than a
collision
The SRS front airbags and SRS side and
curtain shield airbags may also deploy if a
serious impact occurs to the underside of
your vehicle. Some examples are shown in
the illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling

 Approximate distance to object: Less than 1.0 ft. (30 cm) (Corner sensor)
Approximate distance to object: Less than 1.1 ft. (35 cm) (Rear center sensor)
■Buzzer operation and distance to
an obstacle
A buzzer sounds when the sensors are
operating.
 The buzzer beeps faster as the vehi-
cle approaches an obstacle. When
the vehicle comes within the follow-
ing distance of the obstacle, the
buzzer sounds continuously:
• Corner sensors: Approximately 1.0 ft.
(30 cm)
• Rear center sensors: Approximately 1.1 ft. (35 cm)
 When 2 or more obstacles are
detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps. Approximately 4.9 ft. (150 cm)
Approximately 2.3 ft. (70 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect obstacles that are extremely close
to the vehicle.
