VEHICLE SPEED LIMITATION FOR SPECIAL APPLICATIONS
Speed limitation for special applications consists of a switch which is fitted on the
vehicle superstructure. With this switch, the vehicle speed can be limited to a preprogrammed
value. The programmed value can be modified by an authorized
Service dealer on request.
DRIVING STYLE
The following recommendations result in improved economy without adversely
affecting the vehicle speed (i.e. slowing down). In other words: an efficient driving
style.
Driving style in general
Some tips:
- Anticipate traffic and other conditions; release the accelerator pedal in time (zero
fuel consumption) and do not press down on the accelerator when it is not
necessary.
- With low engine loads, try to stay in the green low-rev range whenever possible.
At low engine loads in this rev range the engine has the lowest fuel consumption
per kW output.
- At full load and at full throttle, the engine has the lowest consumption per kW in
the green area.
Note:
In the event of extreme acceleration to 30 to 40 km/h (19 to 25 mph) , and
depending on the vehicle and engine type, the engine management system will
intervene in the control of the engine to prevent excessive engine noise at high revs
and low speeds.
