Gearshift programme control<br />
To optimise vehicle handling the<br />
electronic control unit has the following<br />
memorised programmes:<br />
– automatic operation;<br />
– manual operation;<br />
– winter driving (to be selected<br />
through button WINTER);<br />
– engine warming up;<br />
– protection against excessive gearbox<br />
oil temperature .<br />
Automatic programme<br />
This comprises 16 gearshifting programmes.<br />
In relation to the vehicle speed and<br />
torque transmitted, the control unit<br />
detects the slope of the road surface<br />
and depending on the sporty features<br />
chosen, it autonomously chooses the<br />
programme most suited to the situation.<br />
During gearshifting, the gearbox control<br />
unit asks the injection control unit<br />
to momentarily reduce the torque.<br />
The duration of torque reduction<br />
varies depending on the travelling conditions.
