9-1. Specifications
■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 conditio ns on a specified indoor labora-
tory test wheel.
Sustained high temperature can cause th e 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 performance 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 excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.

ATTENTION
■Précautions relatives aux 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 gonfla-
bles 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 coussins gonflables SRS, notamment le
tampon de volant et les garnitures des montants avant et arrière, sont endomma-
gés ou fissurés, faites-les remplacer par votre concessionnaire Lexus.
■Modification et mise au rebut des compos ants du système de coussins gonflables
SRS
Ne mettez pas le véhicule au rebut et n’effectuez aucune des modifications suivan-
tes sans d’abord consulter votre conces sionnaire Lexus. Les coussins gonflables
SRS pourraient fonctionner de manière in correcte ou se déployer (gonfler) acci-
dentellement, ce qui serait susceptible d’occasionner des blessures graves, voire
mortelles.
●Installation, retrait, démontage et ré paration des coussins gonflables SRS
●Réparations, modifications, retrait ou re mplacement du volant, du bloc d’instru-
mentation, du tableau de bord, des sièges ou du capitonnage des sièges, des
montants avant, latéraux ou arrière et des longerons du toit
●Réparations ou modifications de l’aile ou du pare-chocs avant, ou du côté de
l’habitacle
●Installation d’une protection de calandre (barre safari, barre kangourou, etc.), de
lames de déneigement ou de treuils
●Modifications du système de suspension du véhicule
●Installation d’appareils électroniques tels qu’un émetteur-récepteur radio ou un
lecteur de CD
●Modifications à votre véhicule pour une personne aux capacités physiques rédui-
