SRS airbag precautions
●
Do not hang coat hangers or other hard objects 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 ai rbags 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 and
SRS seat cushion airbag inflate as they may interfere with inflation of the SRS airbags.
Such accessories may prevent the side ai rbags and SRS seat cushion airbag from
activating correctly, disable the system or cause the side airbag s and SRS seat cush-
ion airbag to inflate accidentally, re sulting in death or serious injury.●
Do not strike or apply significant levels of force to the areas around the SRS airbag
components or the front doors.
Doing so can cause the SRS airbags to malfunction. ●
Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot. ●
Do not attach anything to or lean anything
against areas such as the dashboard, steering
wheel pad and lower portion of the instru-
ment panel.
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, side windows, front or rear
pillar, roof side rail and assist grip.

SRS airbag precautions ●
If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation. ●
If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer. ●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision. ■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing de ath or serious injury.●
Installation, removal, disassembl y and repair of the SRS airbags●
Repairs, modifications, removal or replac ement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars, roof side rails,
front door panels, front door trims, or front door speakers ●
Modifications to the front door pa nel (such as making a hole in it)●
Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment ●
Installation of a grille guar d (bull bars, kangaroo bar, etc.), snow plows, winches or
roof luggage carrier ●
Modifications to the vehicle’s suspension system ●
Installation of electronic devices such as mobile two-way radios and CD players●
Modifications to your vehicle for a person with a physical disability

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
front seats, parts of th e 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 subscribers, if the SRS airb ags deploy or in the event
of a severe rear-end collision, the system is designed to send an emergency call to the
response center, notifying 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 emergency and assistance required . If the occupants are unable to communi-
cate, the agent automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. (  P. 5 4 7 )■
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 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 threshold velocity will be considerably higher in the 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 possib le that only the seat belt pretensioners will
activate. ●
The SRS front airbags for the front 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 se at is unoccupied. (  P. 4 9 )●
The SRS seat cushion airbag on the front passenger seat will not operate if the occu-
pant is not wearing a seat belt. ■
SRS airbag deployment conditions (S RS side and curtain shield airbags)●
The SRS side and curtain shield airbags wi ll deploy in the even t of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1 500 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 deploy in the event of a severe frontal colli-
sion.

Conditions under which the SRS airbags may deploy (inflate), ot her than a collision
The SRS front airbags and SRS side and curtain shield airbags may also deploy if a seri-
ous impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the illustra-
tion.
■
Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags do not gene rally inflate if the vehicle is involved in a side or rear
collision, if it rolls over, or if it is involved in a low-speed frontal collision. But, whenever a
collision of any type causes sufficient forwar d deceleration of the vehicle, deployment of
the SRS front airbags may occur. ●
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.
●
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 no t 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.
The SRS side 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.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear
collision, if it pitches end over end, or if it is involved in a low-speed side or lowspeed fron-
tal collision. ●
Collision from the side to the vehicle body
other than the passenger compartment ●
Collision from the side at an angle
●
Collision from the rear ●
