For safety and security Driver’s seat belt buckle switch
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.●
The emergency flashers will be turned on
automatically. ( → P.410)●
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 assi stance 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.355)
• 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/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
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 ●
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.
●
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 event of an impact that
exceeds the set threshold level (the level Q
R
S
T

32 1-1. For safe use
LS500_OM_OM50F54U_(U) 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
■
Types of collisions that may not deploy
the SRS airbags (SRS side and curtain
shield airbags)
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.
●
Collision from the side to the vehicle
body other than the passenger compart-
ment
●
Collision from the side at an angle

strong radio waves or electrical noise●
When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device●
When the electronic key is in contact
with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil
inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs ●
When other wireless ke ys (that emit radio
waves) are being used nearby●
When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a
wireless key that emits radio waves
• Personal computers or personal digital
assistants (PDAs)
• Digital audio players
• Portable game systems ●
If window tint with a metallic content or
metallic objects are attached to the rear
window●
When the electronic key is placed near a
battery charger or electronic devices●
When the vehicle is parked in a pay park-
ing spot where radio waves are emitted.■
Note for the entry function●
Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or
in a high place, or too close to the center
of the rear bumper when the trunk is
opened.
• The electronic key is on the instrument
panel, rear package tray or floor, or in the
door pockets or glove box when the engine is started or engine switch modes
are changed. ●
Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the doors
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle. ●
As long as the electronic key is within the
effective range, the doors may be locked
or unlocked by anyone. However, only
the doors detecting the electronic key
can be used to unlock the vehicle. ●
Even if the electronic key is not inside the
vehicle, it may be po ssible to start the
engine if the electronic key is near the
window. ●
The doors may unlock or lock if a large
amount of water splashes on the door
handle, such as in the rain or in a car
wash, when the electronic key is within
the effective range. (The doors will auto-
matically be locked after approximately
60 seconds if the doors are not opened
and closed.) ●
If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.) ●
Touching the door lock sensor while
wearing gloves may delay or prevent lock
operation. ●
When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●
If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft.
(2 m) or more away from the vehicle.
(Take care to ensure that the key is not
