Votre véhicule est équipé de COUSSINS GONFLABLES INTELLIGENTS
(ADVANCED AIRBAGS) conçus selon les normes de sécurité américaines applicables
aux véhicules à moteur (FMVSS208). Le boît ier électronique de coussins gonflables
(ECU) utilise les informations reçues des capteu rs, etc. détaillés dans le schéma ci-dessus
de composition du système pour commander le déploiement des coussins gonflables. Ces
informations comprennent des in formations sur la gravité de la collision et les occupants.
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.
