To memorise speed

Proceed as follows:

❒ turn the knurled ring (A) to ON and press the accelerator pedal to the required speed;
❒ turn the knurled ring (B) to (+) for at least three seconds, then release it. The car speed is memorised and it is therefore possible to release the accelerator pedal.

In the case of need (when overtaking for instance) acceleration is possible simply pressing the accelerator pedal; later, releasing the accelerator pedal, the car will return to the speed memorised previously.
