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
any time without notice.
Depending on specifications, the vehi-
cle shown in the illustrations may differ
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
affect electronic systems such as:

Multiport fuel injection sys-
tem/sequential multiport fuel injec-
tion system
 Lexus Safety System + A
 Lexus Safety System + 2.0
 Anti-lock brake system
 Vehicle dynamics integrated man-
agement
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your Lexus
dealer for precautionary measures or
special instructions regarding installa-
tion of a mobile two-way radio system.

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.
●All of the doors will be unlocked.
(  P.101)
●The brakes and stop lights will be con-
trolled automatically. ( P.297)
●The interior lights will turn on automati-
cally. ( P.337)
●The emergency flashers will be turned on
automatically. ( P.410)
●Fuel supply to the engine will be stopped.
( P.418)
●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 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

tor light comes on, indicating that the
service is active.
The following indicator light patterns
indicate specific system usage condi-
tions:
Green indicator light on = Active
service
 Green indicator light flashing =
Safety Connect call in process
 Red indicator light (except at vehi-
cle start-up) = System malfunction
(contact your Lexus dealer)
 No indicator light (off) = Safety
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
Safety Connect services
