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.
■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.
●All of the doors will be unlocked.
(  P.89)
●Fuel supply to the engine will be stopped.
( P.294)
●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.52)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a sever rear-end collision.
■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 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
●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]).
●Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.
●All 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

Connect service not active
■Automatic Collision Notification
In case of either airbag deployment or
severe rear-end collision, the system is
designed to automatically call the
response center. The responding agent
receives the vehicle’s location and
attempts to speak with the vehicle
occupants to assess the level of emer-
gency. If the occupants are unable to
communicate, the ag ent automatically
treats the call as an emergency, con-
tacts the nearest emergency services
provider to describe the situation, and
requests that assistance be sent to the
location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety Connect
can work with local authorities to assist
them in locating and recovering the
vehicle. After filing a police report, call
the Safety Connect response center at
1-800-25-LEXUS
(1-800-255-3987) in the United
States, 1-877-539-8777 in Puerto
Rico or 1-800-265- 3987 in Canada,
and follow the prompts for Safety Con-
nect to initiate this service.
In addition to assisting law enforce-
ment with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle
location data may, under certain cir-
cumstances, be shared with third par-
ties to locate your vehicle. Further
information is available at Lexus.com.
■Emergency Assistance Button
(“SOS”)
In the event of an emergency on the
road, push the “SOS” button to reach
the Safety Connect response center.
The answering agent will determine
your vehicle’s location, assess the
emergency, and dispatch the neces-
sary assistance required.
If you accidentally press the “SOS” button,
tell the response-center agent that you are
not experiencing an emergency.
■Enhanced Roadside Assistance
Enhanced Roadside Assistance adds
GPS data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” but-
ton to reach a Safety Connect
response-center agent, who can help
with a wide range of needs, such as:
towing, flat tire, fuel delivery, etc. For a
description of the Roadside Assistance
services and their limitations, please
see the Safety Connect Terms and
Conditions, which are available at
Lexus.com.
Important! Read this information about
exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.

Driving
●In the following situations, if the situation has changed (or the vehicle has been driven for
some time) and the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Lexus dealer.
• When the temperature around the radar sensor is outside of the operational range, such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when driving
in the dark, snow, or fog, or when brig ht lights are shining into the front camera
SituationActions
When the area around a sensor is covered
with dirt, moisture (f ogged up, covered with
condensation, ice, etc.), or other foreign
matterTo clean the part of the windshield in front of
the front camera , use the windshield wipers
or the windshield defo gger of the air condi-
tioning system ( P.219).
When the temperature around the front
camera is outside of the operational range,
such as when the vehicle is in the sun or in an
extremely cold environment
If the front camera is hot, such as after the
vehicle had been parked in the sun, use the
air conditioning system to decrease the tem-
perature around the front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the sun-
light reflected from the surface of the sun-
shade may cause the temperature of the
front camera to become excessively high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold envi-
ronment, use the air conditioning system to
increase the temperature around the front
camera.
The area in front of the front camera is
obstructed, such as when the hood is open
or a sticker is attached to the part of the
windshield in front of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.
