One of my pet peeves is people who REFUSE to read the Owners manual. From section 3-8 page 33 of your owners manual. Now, as to setting the park brake twice. NOT NEEDED if functioning correctly. The problem is a Park Brake switch that is not engaging the first time you set it. Look at the Dash Cluster next time you set the parking brake. IF the Dash Cluster Park brake light does NOT come on, then the Park Brake switch did not engage. If you have a FORD chassis, that is a common problem and Ford can fix it. The reason they do this is to PREVENT watching DVD's in transit. Doug
NOTE: When parked the Radio Power switch
should be set to “HOUSE”, make sure
the park brake is set prior to turning the
vehicle off or the radio may not play
DVDs.
