When we restarted the engine of our motor coach after fueling, the awning automatically extended. It it not supposed to be possible to extend the awning while the engine is on. We were also told there is a safety feature that will not allow the vehicle to drive with the awning extended. When we pulled out of the fueling lane, the awning caught the pump and damaged it.
