For safety and security Driver’s seat position sensor

Airbag sensor assembly
Front impact sensors
Pop Up Hood computer assembly
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 sensors etc.
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 seats, 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.●
All of the doors will be unlocked.
(  P.101)●
The brakes and stop lights will be con-
trolled automatically. (  P.294)
●
The interior lights will turn on automati-
cally. (  P.334)
●
The emergency flashers will be turned on
automatically. (  P.406)
●
Fuel supply to the engine will be stopped.
(  P.414)
●
For Lexus Enform Safety Connect sub-
scribers, 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” but- ton) 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 communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.
(  P.58)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe
rear-end collision. ■
PCS-linked SRS airbag deployment
control (vehicles with Lexus Safety Sys-
tem + A)
If the PCS (Pre-Collision System) deter-
mines that the possibility of a side collision is
high, the SRS side and curtain shield air-
bags will be prepared to operate.
■
SRS airbag deployment conditions (SRS
front airbags/SRS seat cushion airbags)
●
The SRS front airbags and SRS seat cush-
ion airbags will deploy in the event of an
impact that exceed s the set threshold
level (the level of fo rce 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 threshol d velocity will be
considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a P
Q
R
S
T

LS500_OM_(U)_1810 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 th e 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 fr ont airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.●
The SRS seat cushion airbags on the rear
seat will not operate if the occupant is not
wearing a seat belt.■
SRS airbag deployment conditions (SRS
side and curtain shield airbags)●
The SRS side and curtain shield airbags
will deploy in the even t of an impact that
exceeds the set thresh old 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 vehi cle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).●
Both SRS curtain shield airbags may
deploy in the event of a severe side colli-
sion.●
Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.●
Both SRS curtain shield airbags may also
deploy in the event of a severe frontal col-
lision.
■
Conditions under which the SRS air-
bags may deploy (inf late), other than a
collision
The SRS front airbags, SRS curtain shield
airbags and SRS seat cushion 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
The SRS curtain shield airbags may also
deploy under the situations shown in the
illustration. ●
The angle of vehicle tip-up is marginal. ●
The vehicle skids and hits a curb stone.
■
Types of collisions that may not deploy
the SRS airbags (SRS front airbags/SRS
seat cushion airbags)
The SRS front airbags and SRS seat cushion
airbags do not generally inflate if the vehicle
is involved in a side or rear collision, if it rolls
over, or if it is involv ed in a low-speed frontal
collision. But, whenever a collision of any
type causes sufficient forward deceleration
of the vehicle, deploy ment of the SRS front
airbags and SRS seat cushion airbags may
occur. ●
Collision from the side
●
Collision from the rear
●
Vehicle rollover
