An assembly includes a dash and a deployable panel. The deployable panel has a proximal end rotatably connected to the dash. The deployable panel is rotatable about the proximal end from an undeployed position to a deployed position. The proximal end is engaged with the dash in the deployed position and the deployable panel has a distal end spaced above the dash in the deployed position. A member is supported by the dash and translatable upwardly from an undeployed position to a deployed position. The deployable panel abuts the member in the deployed position. The member is rigid relative to the panel in the deployed position. An airbag is supported by the dash and is inflatable to an inflated position. The airbag abuts the panel in the inflated position. The deployable panel is between the airbag and the member.
