Driving
– the brake pedal is operated or
– the vehicle speed is too high (only when driving with Engine Speed Control is
activated) or.
– the MX Engine Brake is engaged or
– the PTO speed control is active via the superstructure.
NOTE: If one or more of the above conditions are met, it is not possible to
engage the Engine Speed Control.
Accelerator pedal function during Engine Speed Control
When the Engine Speed Control is active, the engine speed can be increased above
the control speed using the accelerator pedal. When the accelerator pedal is released,
the engine speed returns to the last valid control speed.
A DAF Service dealer can modify these conditions to meet the customer's
requirements.
7.10 CRUISE CONTROL
The cruise control, as a basic function, can be used to drive at a constant speed. The
desired driving speed is set, and the electronics maintain this speed. The driver can
override the cruise control at any time by depressing the accelerator pedal or by
applying the brakes.
The cruise control behaviour is dynamic, this to ensure a smooth ride and even better
fuel efficiency.
As a result of this dynamic behaviour the actual vehicle speed can drop below the
cruise control set speed in hilly terrain.
NOTE: Every vehicle equipped with cruise control can show this kind of
behaviour.
Adaptive Cruise Control (ACC)
ACC is an addition to the cruise control and is preselected on, as soon as the ignition
of the vehicle is switched on. When the cruise control is engaged, ACC is also
engaged.
ACC is designed to adapt the set cruise control speed to maintain a preset distance
from the vehicle ahead.
For more information about ACC, see section 'Adaptive Cruise Control (ACC)' in
chapter 'Driver assist systems'.
Predictive Cruise Control (PCC)
PCC is an addition to the cruise control and, if fitted, is preselected on, as soon as the
ignition of the vehicle is switched on. When the cruise control is engaged, PCC is also
engaged.
