Ducati Scrambler Manual page 99

When a level other than "OFF" is selected, the
heated handgrips symbol is displayed in the main
page. The turning on of this symbol indicates that
the heated handgrips are ready to be heated.
The actual turning on (heating) of the heated
handgrips occurs only with engine started, when a
certain number of engine rpm have been reached
and maintained. This is to avoid affecting the battery
charge level. .
The actual turning on is indicated with the
appearance of the indication "ON" under the heated
handgrips symbol. (Fig 74)
