■

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 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 warranty.

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.

This information has been prepared in
accordance with regulations issued by
the National Highway Traffic Safety
Administration of the U.S. Department
of Transportation.
It provides the purchasers and/or pro-
spective purchasers of Lexus vehicles
with information on uniform tire quality
grading.

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

Tire section names

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.

Capteurs d'impact avant

Votre véhicule est équipé de COUSSINS GONFLABLES INTELLIGENTS
conçus selon les normes de sécurité américaines applicables aux véhicules à
moteur (FMVSS208). L'ensemble de 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

concernant les coussins gonflables SRS.

Le non-respect de ces précautions peut

occasionner des blessures graves, voire

mortelles.

●

Le conducteur et tous les passagers du

véhicule doivent porter correctement

leur ceinture 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, pouvant occasionner des

blessures graves, voire mortelles, si le

conducteur se trouve très près du

coussin gonflable.

L'autorité fédérale chargée de la sécurité
routière aux États-Unis (NHTSA) con-
seille: La zone à risque du coussin gon-
flable 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 conduc-
teur vous garantit une marge de sécurité
suffisante. Cette distance est à mesurer
entre le centre du volant et le sternum. Si
vous êtes assis à moins de 10 in. (250
mm), vous pouvez changer votre posi-
tion de conduite de plusieurs façons:
• Reculez votre siège le plus possible, de

manière à pouvoir encore atteindre

confortablement les pédales.

403

9-1. For owners

For
owners

AVERTISSEMENT

• Inclinez légèrement le dossier du

siège.

Bien que les véhicules aient une con-

ception différente, un grand nombre

de conducteurs peuvent s'asseoir à

une distance de 10 in. (250 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 recomman-

dations de la NHTSA ci-dessus, tout en

conservant le contrôle des pédales, du

volant et la vue des commandes du tab-

leau de bord.

●

Si vous attachez une rallonge de cein-

ture de sécurité aux boucles de cein-

ture de sécurité avant, sans l'attacher

au pêne de la ceinture de sécurité, les

coussins gonflables frontaux SRS

déterminent que le conducteur et le

passager avant ont attaché leur cein-

ture de sécurité, bien que la ceinture

de sécurité ne soit pas attachée. Dans

ce cas, les coussins gonflables frontaux

SRS peuvent ne pas se déployer cor-

rectement en cas de collision, pouvant

occasionner des blessures graves,

voire mortelles. Veillez à porter la

ceinture de sécurité avec la rallonge

de ceinture de sécurité.

●

Le coussin gonflable passager avant

SRS se déploie également avec une

force considérable, pouvant occasion-

ner des blessures graves, voire mor-

telles, si le passager avant se trouve

très près du coussin gonflable. Le

siège du passager avant doit être éloi-

gné le plus possible du coussin gon-

flable en réglant le dossier de siège de

façon à ce que le passager avant soit

assis bien droit dans le siège.

404

9-1. For owners

AVERTISSEMENT

●

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. Lexus recom-

mande 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.

●

N'installez jamais un siège de sécurité

enfant type dos à la route sur le siège

passager avant, même si le témoin

indicateur “AIR BAG OFF” est allumé.

En cas d'accident, la force engendrée

par le déploiement rapide du coussin

gonflable du passager avant peut

blesser grièvement, voire tuer l'enfant

si le siège de sécurité enfant type dos à

la route est installé sur le siège du pas-

sager avant.

●

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.

●

Ne laissez pas les occupants des

sièges avant voyager avec un objet sur

les genoux.

●

Ne vous appuyez pas contre la porte,

le rail latéral de toit ou les montants

avant, latéraux et arrière.

●

Ne laissez personne s'agenouiller sur

les sièges passagers en appui contre la

porte ou sortir la tête ou les mains à

l'extérieur du véhicule.
