Open Door Brake - Volvo 9700 US/CAN 2016 Driver's Handbook Manual

The Volvo 9700 US/CAN is equipped with
the open door brake function.
This function works as follow:
•
If the bus is stopped and the service door
are open. The bus will not be able to
move (because the throttle signal will
be deactivated and also the gear selector
in the transmission will locked, this
previously only applies for buses that are
equipped with I-Shift transmission, or
any transmission multiplexed to the bus
electrical system). Also too, the parking
brakes will remain applied. So that should
be close to the service door to be able
move the bus.
•
If the bus is in motion, the service doors
may not be open until the bus is totally
stopped.
The open door brake function goes active
only when it has the following conditions:

general activation button which located
