Disengage Acc; Inactivate Acc; Change Speed - Volvo FM Handbook

Disengage ACC

The cruise control is disengaged by:
• depressing the brake pedal,
• moving the control (3) to "OFF", or
• moving the retarder stalk to any other position than
A.
The previously set speed is retained in the memory. It
can be resumed by moving the control (3) to
"RESUME". A temporary increase of speed, e.g. when
overtaking, does not interfere with the cruise control's
function.

Inactivate ACC

By switching off the traction control via the "Vehicle
settings" menu in the display, the ACC is inactivated
at the same time. Inactivation of ACC is suitable when
the truck is on rollers, for example dynatests, authority
tests, vehicle inspections or similar.
To re-engage ACC the truck must be restarted.
For more information about traction control, see
"Driver's manual EBS".

Change speed

Change the preset speed by short presses on + or – on
SET (1). The preset speed can also be changed by
using the accelerator pedal and SET (1).
The set speed in ACC is shown by a green LED
alongside the corresponding speed in the speedometer.
The set speed is shown in intervals of 5 km/h. In the
figure, the speed is set between 73 and 77 km/h.
