Level Control - Volvo 9700 US/CAN 2016 Driver's Handbook Manual

Level control

The ground clearance of the bus (suspension
height) can be adjusted with this switch.
•
To lower the bus press the lower part of
the switch, e.g. while passing under a low
bridge.
•
To raise the bus press the upper part of the
switch, e.g. while driving onto a ferry.
Note: Levelling control should only be used
temporarily. During normal driving the
switch must be in the middle position.
When the bus reaches the selected level a
symbol is shown on the display panel.
The suspension system attempts to keep the
bus at a constant ride height independent
of the load. Any faults in the system are
indicated by a symbol on the display panel.
Note: If the air suspension of the bus is in the
highest or lowest position and the bus speed
exceeds 12 mph (20 km/h), a message alert
is sent to the display driver, therefore, the
acceleration pedal is deactivated (Showing
the corresponding symbol on the driver
display, see the following section on this
manual: "Accelerator pedal deactivated",
page 19).
