how to maintain your vehicle and enables you to

correctly perform your own maintenance.

The best way to keep your new vehicle in top running

order is to maintain it properly from the moment you

drive it off the showroom floor.

The Lexus authorized Repair Manual is packed with

literally everything you need to know to perform your

own maintenance in virtually every area of your new

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, chest and

knee injuries by preventing contact of the head, chest and knee

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.

Accessories, spare parts and modification of

your Lexus

A wide variety of non-genuine spare parts and accessories for

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 478 and 390.

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,

system 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.
