For your information
Main Owner’s Manual
Please note that this manual applies to all models and explains all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. How-
ever, 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 vehicle sh own in the illustration may differ from
your vehicle in terms of color and equipment.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage 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 violate governmental regula tions. In addition, damage or perfor-
mance problems resulting from the modification may not be covered under war-
ranty.
Installation of a mobile two-way radio system
As the installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as the multiport fuel injection system/sequential multiport
fuel injection system, cruise control syst em, anti-lock brake system, SRS airbag sys-
tem and seat belt pretensioner system, be sure to check with your Lexus dealer for
precautionary measures or special instructions regarding installation.

17
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus deal er before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.d tsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that will hurt or kill you, your occupants or others.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full at tention to driving. Anything that distracts
the driver, such as adjusting controls, ta lking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■General precaution regarding children’s safety
Never leave children unattended in the vehi cle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or othe r features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause significant injury to the occupants. They
work together with the seat belts to he lp reduce the risk of death or serious
injury.
SRS front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and ches t of the driver and front passen-
ger from impact with interior components.
Knee airbags
Can help provide driver and front passenger protection.
SRS side and curtain shield airbags
SRS side airbags
Can help protect the torso of the front seat occupants.
SRS curtain shield airbags
Can help protect primarily the head of outside occupants.

Airbag system componentsYour vehicle is equipped with AD VANCED AIRBAGS designed based
on US motor vehicle sa fety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system con sists of the front passenger occupant
classification sensor etc.
The main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.

1-7. Safety information
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■SRS warning light
This warning light system monitors the airb ag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, inte rconnecting wiring and power sources.
(  P. 3 8 4 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel , airbag cover and inflator) as well as
the front seats, and parts of the front pill ar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. ( P. 9 5 )

Before driving
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield airbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS side airbag on the passenger seat will not activate if there is no passen-
ger sitting in the front passenger seat. Ho wever, the side airbag on the passen-
ger seat may deploy if luggage is put in th e seat, even if the seat is unoccupied.
(  P. 9 5 )
■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not de ploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to 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 colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of th e SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the side
●Collision from the rear
●Vehicle rollover
