Driving
PCC is designed to read and predict road situations ahead and adapt vehicle speed,
engine torque and, if an automated gearbox is installed, shift and EcoRoll behaviour.
The aim is to keep overall speed during the trip like that of a vehicle without PCC and,
at the same time, increase driveability and reduce fuel consumption.
For more information about PCC, see section 'Predictive Cruise Control (PCC)' in
chapter 'Driver assist systems'.
Engaging and disengaging conditions for the cruise control
Engaging conditions
The cruise control can be engaged when all of the following conditions are fulfilled:
– The engine is running.
– The vehicle speed exceeds 30 km/h (18 mph) (ex-factory).
– No braking functions are active.
– Variable speed limiter is not active.
– Forward Collision Warning of the ACC is not active.
– Vehicle Stability Control (VSC) is not active.
– Anti Slip Regulation (ASR) is not active.
– The drive line is not interrupted by the driver (clutch pedal operated, neutral gear
selected in case of an automated gearbox).
Disengaging conditions
The cruise control is disengaged by any of the following conditions:
– Engine is not running.
– The vehicle speed falls below 25 km/h (16 mph) (ex-factory).
– The park brake or brake pedal are operated.
– Steering wheel switch 'OFF' is operated.
– Variable speed limiter is active.
– Forward Collision Warning is active.
– Vehicle Stability Control (VSC) is active.
– Anti Slip Regulation (ASR) is active for 3 seconds.
– The drive line is interrupted by the driver (clutch pedal operated, neutral gear
selected in case of an automated gearbox).
NOTE: A DAF Service dealer can change the vehicle speed settings for
activation and/or deactivation of the cruise control to the customer's
requirements.
Using the cruise control
If properly used the cruise control has a positive influence on fuel economy. Use the
cruise control as soon as it is possible to drive for a longer period at a constant speed.
It is advisable not to use the cruise control when driving in urban areas.
NOTE: Using the cruise control incorrectly can lead to increased fuel
consumption.
