LX570_OM_OM60N01U_(U) WA R N I N G ■
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 h ood, do not open the hood until the steam
has subsided. The engine compartment 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 seri-
ous injury. ●
Do not loosen the radiator cap or the coolant reservoir cap while the engine and radi-
ator are hot. High temperature 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. ■
To prevent damage to the cooling system
Observe the following precautions: ●
Avoid contaminating the coolant with foreign matter (such as sand or dust etc.). ●
Do not use any coolant additives.

Vehicle specifications ■
Temperature A, B, C
The temperature grades are A (the highes t), B, and C, representing the tire’s
resistance to the generation of heat and its ability to dissipate heat when
tested under controlled conditions 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 excessiv e loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.

the beads are laid at substantially 90 degrees to the
centerline of the tread
Reinforced tire A tire designed to operate at higher loads and at higher
inflation pressures than the corresponding standard tire
Section width The linear distance between the exteriors of the side-
walls of an inflated tire, excluding elevations due to
labeling, decoration, or protective bands
Sidewall That portion of a tire between the tread and bead
Sidewall separation The parting of the rubber compound from the cord
material in the sidewall
Snow tire A tire that attains a traction index equal to or greater
than 110, compared to the ASTM E-1136 Standard Ref-
erence Test Tire, when using the snow traction test as
described in ASTM F-1805-00, Standard Test Method

Précautions relatives aux coussins gonflables SRS
●
N’accrochez pas de cintres ni d’autres ob jets rigides sur les crochets porte-vête-
ments. Tous ces objets pour raient se transformer en pr ojectiles et vous occasionner
des blessures graves, voire mortelles, en cas de déploiement des coussins gonflables
SRS en rideau. ●
Si le recouvrement de vinyle est placé sur la zone de déploiement du coussin gon-
flable SRS de protection des genoux, veillez à le retirer.●
N’utilisez pas d’accessoires recouvrant les pa rties du siège où les coussins gonflables
SRS latéraux se déploient, car ces access oires pourraient entraver le déploiement
des coussins gonflables. De tels accessoires peuvent empêcher les coussins gon-
flables latéraux de se déployer correctement, rendre le système inopérant ou provo-
quer accidentellement le déploiement des coussins gonflables latéraux,
occasionnant des blessures graves, voire mortelles. ●
Ne frappez pas et n’appliquez pas une pr ession importante à l’emplacement des
composants des coussins gonflables SRS.
Cela peut provoquer un mauvais foncti onnement des coussins gonflables SRS.●
Ne touchez à aucun composant des coussins gonflables SRS immédiatement après
leur déploiement (gonflage), car ils pourraient être chauds. ●
Si vous avez de la difficulté à respirer après le déploiement des coussins gonflables
SRS, ouvrez une portière ou une glace pour laisser entrer l’air, ou quittez le véhicule
si vous pouvez le faire en toute sécurité. Dès que possible, nettoyez tous les résidus
afin d’éviter les irritations cutanées. ●
Si les emplacements de stockage des coussi ns gonflables SRS, tels que le tampon de
volant et les garnitures des montants avant, latéraux et arrière, sont endommagés ou
fissurés, faites-les remplacer par votre concessionnaire Lexus. ●
Ne placez aucun objet, par exemple un coussin, sur le siège du passager avant. Cela
disperserait le poids du passager, ce qui empêcherait le capteur de le détecter cor-
rectement. Cela pourrait empêcher le dé ploiement des coussins gonflables SRS du
passager avant en cas de collision. ●
Ne fixez rien sur des zones telles que les
portières, le pare-brise, les glaces de
portières, les montants avant, latéraux ou
arrière, le brancard de pavillon et la poignée
de maintien.
