IMPORTANT INFORMATIONABOUT YOUR LEXUS
Occupant restraint systems
Lexus encourages you and your family to take the time to read
Section 1-6 of this Owner's Manual carefully. In terms of
helping you understand how you can receive the maximum
benefit of the occupant restraint systems this vehicle provides,
Section 1-6 of this Owner's Manual is the most important
Section for you and your family to read.
Section 1-6 describes the function and operation concerning
seats, seat belts, SRS airbags and child restraint systems of
this vehicle and some potential hazards you should be aware
of. These systems work together along with the overall
structure of this vehicle in order to provide occupant restraint
in the event of a crash. The effect of each system is enhanced
when it is used properly and together with other systems. No
single occupant restraint system can, by itself, provide you or
your family with the equal level of restraint which these
systems can provide when used together. That is why it is
important for you and your family to understand the purpose
and proper use of each of these systems and how they relate
to each other. The purpose of all occupant restraint systems is to help reduce
the possibility of death or serious injury in the event of a
collision. None of these systems, either individually or
together, can ensure that there is no injury in the event of
collision. However, the more you know about these systems
and how to use them properly, the greater your chances
become of surviving an accident without death or serious
injury.
Seat belts provide the primary restraint to all occupants of the
vehicle, and every occupant of the vehicle should wear seat
belts
properly at all times. Children should always be secured
in child restraint systems that are appropriate for their age and
size. SRS (Supplemental Restraint System) airbags are, as
their names imply, designed to work with, and be supplemental
to, seat belts and are not substitutes for them. SRS airbags
can be very effective in reducing the risk of head and chest
injuries by preventing contact of the head and chest with
interior portions of the vehicle.
In order to be effective, the SRS airbags must deploy with
tremendous speed. The rapid deployment of the SRS airbags
makes the SRS airbags themselves potential sources of
serious injury if an occupant is too close to an airbag, or if an
object or some part of his or her body has been placed between
the occupant and the airbag at the time of deployment. This
is just one example of how the instructions in Section 1-6 of
this Owner's Manual will help ensure proper use of the
occupant restraint systems, and increase the safety they can
provide to you and your family in the event of an accident.
Lexus recommends you to read the provisions in Section 1-6
carefully and refer to them as needed during your time of
ownership of this vehicle.

IMPORTANT INFORMATION ABOUT YOUR LEXUS
iv
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 af fect its performance, safety or durability, and may even
violate governmental regulations. In addition, damage or
performance pro blems resulting from the modification may not
be covered under warranty.
If you install any Genuine Accessories such as a bull-bar,
winch, etc., consult your Lexus dealer.
Spark ignition system of your Lexus
The spark ignition system in your Lexus meets all
requirements of the Canadian Interference- Causing
Equipment Standard.
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 system, anti-lock brake system, SRS airbag
system and seat belt pretensioner system, be sure to check
with your Lexus dealer for precautionary measures or special
instructions regarding installation.
Tires and loading on your Lexus
Underinflated or overinflated tire pressure and the
excess load may result in the deterioration of steering
ability and braking ability, leading to an accident.
Check the tire inflation pressure periodically and be
sure to keep the load limits given in this Owner's
Manual. For details about tire inflation pressure and
load limits, see pages 578 and 472.
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 a 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
dealer before you scrap your vehicle.

the ignition switch is on. The engine operating
temperature w ill vary with changes in weather and engine
load.
If the needle points to the red zone or higher, stop your vehicle
and allow the engine to cool.
Your vehicle may overheat during severe operating conditions,

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the ONº position. It goes off after about 6 seconds. This
means the SRS airbags and front seat belt pretensioners
are operating properly.
This warning light system monitors the airbag 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,
front seat belt pretensioner assemblies, inflators, warning light,
RSCA OFFº indicator light, interconnecting wiring and power
sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
 The light does not come on when the ignition key is turned
to the ONº position or remains on for more than 6 seconds
or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags have a problem. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.
(e) Malfunction Indicator Lamp
This lamp comes on when the ignition key is turned to the
ONº position and goes off after the engine starts. This
means that the warn ing light system is operating properly.
If the lamp remains on, or the lamp comes on while driving,
first check the followings.
 Empty fuel tank
If the fuel tank is empty, refuel immediately.
 Loose fuel tank cap
If the fuel tank cap is loose, securely tighten it.
These cases are temporary malfunctions. The malfunction
indicator lamp will go off after taking several driving trips.
If the lamp does not go off even after several trips, contact your
Lexus dealer as soon as possible.
If the fuel tank is not empty or the fuel tank cap is not
loose...
 There is a problem somewhere in the engine, emission
control system, electronic throttle control system, automatic
transmission electrical system or warning light system itself.
Contact your Lexus dealer as soon as possible to service the
vehicle.
If engine speed does not increase when the accelerator pedal
is depressed, there may be a problem somewhere in the
electronic throttle control system.
