Gasoline quality

In very few cases, driveability problems may

be caused by the brand of gasoline you are

using. If driveability problems persist, try

changing the brand of gasoline. If this does

not correct the problem, consult your Lexus

dealer.

■

Recommendation of the use of gasoline

containing detergent additives

●

Lexus recommends the use of gasoline

that contains detergent additives to avoid

the build-up of engine deposits.

●

All gasoline sold in the U.S.A. contains

minimum detergent additives to clean

and/or keep clean intake systems, per

EPA’s lowest additives concentration pro-

gram.

●

Lexus strongly recommends the use of

Top Tier Detergent Gasoline. For more

information on Top Tier Detergent Gaso-

line and a list of marketers, please go to

the official website www.toptiergas.com.

■

Recommendation of the use of low

emissions gasoline

Gasolines containing oxygenates such as

ethers and ethanol, as well as reformulated

gasolines, are available in some cities.

These fuels are typically acceptable for use,

providing they meet other fuel require-

ments.
Lexus recommends these fuels, since the

formulations allow for reduced vehicle

emissions.

■

Non-recommendation of the use of

blended gasoline

●

Use only gasoline containing up to 15%

ethanol.

DO NOT use any flex-fuel or gasoline

that could contain more than 15% etha-

nol, including from any pump labeled
E30 (30% ethanol [

]), E50 (50%

ethanol [

]), E85 (85% ethanol [

])

(which are only some examples of fuel

containing more than 15% ethanol).

●

If you use gasohol in your vehicle, be sure

that it has an octane rating no lower than

91.

●

Lexus does not recommend the use of

gasoline containing methanol.

■

Non-recommendation of the use of gas-

oline containing MMT

Some gasoline contains an octane enhanc-

ing additive called MMT (Methylcyclopen-

tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-

oline that contains MMT. If fuel containing

MMT is used, your emission control system

may be adversely affected.
The malfunction indicator lamp on the

instrument cluster may come on. If this hap-

pens, contact your Lexus dealer for service.

■

If your engine knocks

●

Consult your Lexus dealer.

●

You may occasionally notice light knock-

ing for a short time while accelerating or

Fuel information

You must only use unleaded gaso-
line.

Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number of 96)
or higher required for optimum
engine performance and fuel econ-
omy. If the octane rating is less than
91, damage to the engine may
occur and may void the vehicle war-
ranty.

At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A.

driving uphill. This is normal and there is

no need for concern.

NOTICE

■

Notice on fuel quality

●

Do not use improper fuels. If improper

fuels are used, the engine will be dam-

aged.

●

Do not use leaded gasoline.

Leaded gasoline can cause damage to

your vehicle’s three-way catalytic con-

verters causing the emission control

system to malfunction.

●

Do not use gasohol other than the type

previously stated.

Other gasohol may cause fuel system

damage or vehicle performance prob-

lems.

●

Using unleaded gasoline with an

octane number or rating lower than

the level previously stated may cause

persistent heavy knocking.

At worst, this may lead to engine dam-

age and will void the vehicle warranty.

■

When refueling with gasohol

Take care not to spill gasohol. It can dam-

age your vehicle’s paint.

■

Fuel-related poor driveability

If poor driveability (poor hot starting,

vaporization, engine knocking, etc.) is

encountered after using a different type

of fuel, discontinue the use of that type of

fuel.

Your Lexus dealer will help answer any
questions you may have as you read this
information.

■

DOT quality grades

All passenger vehicle tires must con-
form to Federal Safety Requirements in
addition to these grades. Quality
grades can be found where applicable
on the tire sidewall between tread
shoulder and maximum section width.

For example: Treadwear 200 Traction AA
Temperature A

■

Treadwear

The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.

For example, a tire graded 150 would wear
one and a half (1 - 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete.

A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight

ahead) traction tests and does not include
cornering (turning) traction.

■

Temperature A, B, C

The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.

Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is properly inflated and not
overloaded.
Excessive speed, underinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.

For owners

• Peut contribuer à empêcher les occupants d’être éjectés du véhicule en cas de tonneau

Votre véhicule est équipé de COUSSINS GONFLABLES INTELLIGENTS
conçus selon les normes de sécurité américaines applicables aux véhicules à
moteur (FMVSS208). L'ensemble des capteurs de coussins gonflables (ECU)
régule le déploiement des coussins gonflables sur la base des informations qu'il
reçoit des capteurs, etc., indiqués ci-dessus dans le schéma illustrant les com-
posants du système. Parmi ces informations figurent la gravité du choc et l'occupa-
tion du véhicule par les passagers. Le déploiement rapide des coussins gonflables
est obtenu au moyen d'une réaction chimique dans les dispositifs pyrotechniques,
qui produit un gaz inoffensif permettant d'amortir le mouvement des occupants.

AVERTISSEMENT

■

Précautions relatives aux coussins

gonflables SRS

Respectez les précautions suivantes.

Le non-respect de ces précautions peut

occasionner des blessures graves, voire

mortelles.

●

Le conducteur et tous les passagers

doivent porter correctement leur cein-

ture de sécurité.

Les coussins gonflables SRS sont des

dispositifs supplémentaires à utiliser

avec les ceintures de sécurité.

●

Le coussin gonflable conducteur SRS

se déploie avec une force con-

sidérable et peut occasionner des

blessures graves, voire mortelles, tout

particulièrement si le conducteur se

trouve très près du coussin gonflable.

L'autorité fédérale chargée de la sécu-

rité routière aux États-Unis (NHTSA)

conseille:

La zone à risque du coussin gonflable
conducteur se situant dans les premiers
2 à 3 in. (50 à 75 mm) de déploiement,
vous placer à 10 in. (250 mm) de votre
coussin gonflable conducteur vous
garantit une marge de sécurité suffisante.
Cette distance est à mesurer entre le
centre du volant et le sternum. Si votre
position de conduite actuelle vous place
à moins de 10 in. (250 mm) du coussin
gonflable conducteur, vous pouvez
changer votre position de conduite de
plusieurs façons:
• Reculez votre siège le plus possible, de

manière à pouvoir encore atteindre

confortablement les pédales.

572

9-1. For owners

AVERTISSEMENT

• Inclinez légèrement le dossier de

siège. Bien que les véhicules aient une

conception différente, un grand nom-

bre de conducteurs peuvent s'asseoir

à une distance de 10 in. (251 mm),

même avec le siège conducteur com-

plètement avancé, simplement en

inclinant un peu le dossier de siège. Si

vous avez des difficultés à voir la route

après avoir incliné le dossier de votre

siège, utilisez un coussin ferme et

antidérapant pour vous rehausser ou

remontez le siège si votre véhicule est

équipé de cette fonction.

• Si votre volant est réglable, inclinez-le

vers le bas. Cela a pour effet d'orienter

le coussin gonflable en direction de

votre poitrine plutôt que de votre tête

et de votre cou. Réglez votre siège

selon les recommandations de la

NHTSA, tout en conservant le con-

trôle du véhicule avec les pédales et le

volant, et en préservant la vue des

commandes du tableau de bord.

●

Si vous attachez une rallonge de cein-

ture de sécurité à une boucle de cein-

ture de sécurité du passager avant

sans l’attacher au pêne de la ceinture

de sécurité, le système de coussins

gonflables SRS détermine que le pas-

sager avant a attaché sa ceinture de

sécurité, bien que la ceinture de sécu-

rité ne soit pas bouclée. Dans ce cas,

les coussins gonflables frontaux SRS

du passager avant peuvent ne pas se

déployer correctement lors d’une col-

lision, pouvant occasionner des bless-

ures graves, voire mortelles. Veillez à

porter la ceinture de sécurité cor-

rectement en cas d’utilisation d’une

rallonge de ceinture de sécurité.

●

Le coussin gonflable frontal SRS se

déploie avec une force considérable et

peut occasionner des blessures

graves, voire mortelles, tout particu-

lièrement si le passager avant se

trouve très près du coussin gonflable.

Le siège du passager avant doit être

éloigné le plus possible du coussin

gonflable, avec le dossier réglé de

façon à ce que le passager avant soit

assis bien droit dans le siège.

●

Les nourrissons et les enfants qui ne

sont pas correctement assis et/ou

attachés peuvent être grièvement

blessés ou tués par le déploiement

d'un coussin gonflable. Un nourrisson

ou un enfant trop petit pour utiliser une

ceinture de sécurité doit être cor-

rectement attaché au moyen d'un

siège de sécurité enfant. Toyota

recommande vivement d'installer tous

les nourrissons et enfants sur les sièges

arrière du véhicule et de prévoir pour

eux des systèmes de retenue adaptés.

Les sièges arrière sont plus sûrs pour

les nourrissons et les enfants que le

siège du passager avant. (



P.42)

●

Ne vous asseyez pas sur le bord du

siège et ne vous appuyez pas contre la

planche de bord.

●

Ne laissez pas un enfant rester debout

devant le coussin gonflable passager

avant SRS ou s'asseoir sur les genoux

du passager avant.

573

9-1. For owners

For owners

AVERTISSEMENT

●

Les occupants des sièges avant ne

doivent en aucun cas tenir d'objets sur

leurs genoux.

●

Ne vous appuyez pas contre la porte,

le rail latéral de toit ou les montants

avant, latéraux ou arrière.

●

Ne laissez personne s'agenouiller sur

un siège en appui contre la porte ou

sortir la tête ou les mains à l'extérieur

du véhicule.

●

Ne fixez rien et ne posez rien sur des

emplacements tels que la planche de

bord, la garniture du volant et la partie

inférieure du tableau de bord.

●

Ne fixez rien à des emplacements tels

que les portes, la vitre du pare-brise,

les vitres latérales, les montants avant

ou arrière, des rails latéraux de toit et

des poignées de maintien.

●

Ne suspendez aucun cintre ou objet

dur aux crochets à vêtements. Ces

éléments peuvent se transformer en

projectiles si les coussins gonflables

rideaux SRS se déploient, le choc pou-

vant entraîner des blessures graves,

voire mortelles.

●

Si un cache en vinyle est fixé sur la

zone où le coussin gonflable de

genoux SRS se déploie, veillez à le

retirer.

574

9-1. For owners

AVERTISSEMENT

●

N'utilisez aucun accessoire de siège

recouvrant les zones de déploiement

des coussins gonflables SRS, car il ris-

que de gêner le déploiement des

coussins gonflables SRS. De tels

accessoires peuvent empêcher les

coussins gonflables SRS de se

déployer correctement, peuvent dés-

activer le système ou entraîner le

déploiement involontaire des coussins

gonflables SRS, ce qui peut éventuel-

lement occasionner des blessures

graves, voire mortelles.

●

Évitez de faire subir des chocs ou des

pressions excessives aux composants

des systèmes de coussins gonflables

SRS, aux portes avant ou à leur zone

adjacente.

En effet, cela pourrait entraîner un dys-

fonctionnement des coussins gonfla-

bles SRS.

●

Ne touchez aucun composant des

coussins gonflables SRS immédiate-

ment après leur déploiement (gon-

flage), car ils peuvent être chauds.

●

Si vous avez des difficultés à respirer

après le déploiement des coussins

gonflables SRS, ouvrez une porte ou

une vitre pour faire entrer de l'air frais,

ou bien descendez du véhicule si cela

ne présente pas de danger. Essuyez

tout résidu dès que possible afin

d'éviter d'éventuelles irritations de la

peau.

●

Si les parties renfermant les coussins

gonflables SRS, comme les garnitures

du volant et des montants avant et

arrière, sont endommagées ou cra-

quelées, faites-les remplacer par votre

concessionnaire Lexus.

●

Ne placez rien sur le siège du pas-

sager avant, comme un coussin par

exemple. Cela a pour conséquence de

répartir le poids du passager sur toute

la surface du siège, ce qui empêche le

capteur de détecter correctement le

poids du passager. En conséquence,

les coussins gonflables frontaux SRS

du siège du passager avant risquent de

ne pas se déployer en cas de collision.

■

Modification et mise au rebut des

composants du système de coussins

gonflables SRS

Ne mettez pas votre véhicule au rebut et

ne procédez à aucune des modifications

suivantes sans consulter votre conces-

sionnaire Lexus. Les coussins gonflables

SRS peuvent ne pas fonctionner cor-

rectement ou se déployer involontaire-

ment, ce qui peut provoquer des

blessures graves, voire mortelles.
