When trouble arises
edly. (The fans may not operate in freezing
temperatures.)
7If the fans are not operating:
Stop the engine immediately and
contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the
nearest Lexus dealer.
8 Check if “Engine Coolant Temp
High Stop in a Safe Place See
Owner’s Manual” is shown on the
multi-information display.
If the message does not disappear:
Stop the engine and contact your
Lexus dealer.
If the message is not displayed:
Have the vehicle inspected at the
nearest Lexus dealer.
WARNING
■When inspecting under the hood of
your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
●If steam is seen coming from under the
hood, do not open the hood until the
steam has subsided. The engine com-
partment may be very hot.
●Keep hands and clothing (especially a
tie, a scarf or a muffler) away from the
fans and belts.
Failure to do so may cause the hands
or clothing to be caught, resulting in
serious injury.
●IS350 AWD/IS350/IS300 AWD:
Do not loosen the coolant inlet cap or
coolant reservoir cap while the engine
and radiator are hot. (The coolant inlet
cap is located under the engine cover.)
High temperature steam or coolant
could spray out.
●IS300: Do not loosen the coolant inlet
cap, coolant reservoir cap, or inter-
cooler reservoir cap while the engine
and radiator are hot. High tempera-
ture steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has
cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can
cause damage to the engine.

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 Fede ral 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, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.

4109-1. For owners
Capteurs d'impact avant
Votre véhicule est équipé de CO USSINS GONFLABLES INTELLIGENTS
conçus selon les normes de sécurité américaines applicables aux véhicules à
moteur (FMVSS208). L'ensemble de cap teurs de coussins gonflables (ECU)
régule le déploiement des coussins gonfla bles 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.R
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 ceinture s 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 ch argée 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 vola nt 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.

AVERTISSEMENT
●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.
Ces éléments peuvent se transformer
en projectiles lorsque les coussins
gonflables conducteur, passager avant
et genoux SRS se déploient.
●Ne fixez rien aux portes, à la vitre du
pare-brise, aux vitres latérales, aux
montants avant et arrière, au rail latéral
de toit et à la poignée de maintien.
●Ne suspendez aucun cintre ou objet
dur aux crochets à vêtements. Tous
ces objets pourraient se transformer
en projectiles et causer des blessures
graves, voire mortelles en cas de
déploiement des coussins gonflables
rideaux SRS.
●Si un cache en vinyle est placé sur la
zone où le coussin gonflable de
genoux SRS se déploie, assurez-vous
de le retirer.
●N'utilisez aucun accessoire de siège
recouvrant les zones de déploiement
des coussins gonflables latéraux SRS,
car il risque de gêner le déploiement
des coussins gonflables SRS. De tels
accessoires peuvent empêcher les
coussins gonflables latéraux de
fonctionner correctement, désactiver
le système ou entraîner le déploiement
accidentel des coussins gonflables
latéraux, occasionna nt des blessures
graves, voire mortelles.
●Évitez de faire subir des chocs ou des
pressions excessives aux parties ren-
fermant les composants de coussins
gonflables SRS. En effet, cela pourrait
entraîner un dysfonctionnement des
coussins gonflables SRS.
●Ne touchez aucun composant
immédiatement après le déploiement
(gonflage) des coussins gonflables
SRS, car ils peuvent être chauds.
●Si vous avez des di fficultés 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'éventuelle s irritations de la
peau.
●Si les partie s 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 passager avant risquent de ne pas
se déployer en cas de collision.
