❑
Après le montage et la filerie, il est nécessaire de vérifier
le bon fonctionnement des autres appareils électriques.
Le fait de continuer à les utiliser dans des conditions anormales
peut déclencher un incendie, provoquer un choc électrique ou un
accident de la route.
❑
En cas de montage dans un véhicule équipé de coussins
gonflables, vérifier les avertissements et précautions
préconisés par le constructeur automobile avant de
procéder au montage.
❑
S’assurer que les fils n’interfèrent pas avec la conduite ou
le fait d’entrer dans le véhicule et d’en sortir.
