First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.

CAUTION
■Speed limit when using the compact spare tire
Do not drive at speeds in excess of 50 mph (80 km/h) when a compact spare tire
is installed on the vehicle.
The compact spare tire is not designed for driving at high speeds. Failure to
observe this precaution may lead to an accident causing death or serious injury.
■After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their stor-
age location to reduce the possibility of personal injury during a collision or sudden
braking.

Do not fit tire chains to the compact spare tire.
Tire chains may damage the vehicle body and adversely affect driving perfor-
mance.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and trans-
mitter may be damaged if not handled correctly.

■Ceintures de sécurité
Avec un chiffon ou une éponge, nettoyez à l’aide d’un savon doux et de
l’eau tiède. Vérifiez aussi les ceintures régulièrement pour vous assurer
qu’elles ne présentent pas d’usure excessive, d’effilochage ou de cou-
pures.
Entretien et soin
ATTENTION
■Dommages et usure de la ceinture de sécurité
Vérifiez périodiquement le système de ceintures de sécurité. Assurez-vous qu’il
n’y a pas de coupures, d’effilochures ni de pièces desserrées. N’utilisez pas une
ceinture de sécurité endommagée avant qu’elle ne soit remplacée. Les ceintures
de sécurité endommagées ne peuvent pas protéger les occupants contre les
blessures graves, voire mortelles.

GS450h_OM_OM30D52U_(U)Votre véhicule est doté de COUSSINS GONFLABLES ÉVOLUÉS dont
la conception s’appuie sur les normes de sécurité des véhicules à moteur
américains (FMVSS208). Le module de capteur de coussin gonflable
(ECU) contrôle le déploiement des coussins gonflables en fonction des
informations obtenues des capteurs et d’autres éléments affichés dans le
diagramme des composants du système ci-dessus. Ces informations
comprennent des données relatives à la
gravité de l’impact et aux passag-
ers. Au moment du déploiement des coussins gonflables, une réaction
chimique se produit dans les gonfleurs et les coussins gonflables se remp-
lissent rapidement d’un gaz non toxique pour limiter le mouvement des
occupants.
