Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanations for equipment
not installed on your vehicle.
All specifications provided in this man-
ual are current at the time of printing.
However, because of the Lexus policy
of continual product improvement, we
reserve the right to make changes at

from your vehicle in terms of color and
equipment.
Approximately five hours after the
engine is turned off, you may hear
sound coming from under the vehicle
for several minutes. This is the sound of
a fuel evaporation leakage check and,
it does not indicate a malfunction.
A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance, repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
The installation of a mobile two-way
radio system in your vehicle could

RX350L: Rear side airbags (outboard second-row seats)
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 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.98)
●The brakes and stop lights will be con-
trolled automatically. ( P.278)
●The interior lights will turn on automati-
cally. ( P.314)
●The emergency flashers will turn on auto-
matically. ( P.404)
●Fuel supply to the engine will be stopped.
( P.412)
●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.60)
• 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)
●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 seat cushion airbag on the front
passenger 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
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-

towing, flat tire, fuel delivery, etc. For a

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.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
ANSI (American National Stan-
dards Institute) C95.1 [1992]
 NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
 ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.
