Closing The Passenger Door in 171 and 172
Watch the below video to see how to close the door in 171 and 172. If you hold the close door button a moment longer after it closes it will reopen the door and start beeping at you. You will then need to reopen the door slightly to stop the beeping. Then close the door again, making sure to take your finger off the close button thew moment the door fully closes.
Take a moment to practice this without clients on the bus so you become comfortable with closing the passenger door.
