Electric System : Basics
Manual mode
• Manual to AUTO mode subjected to gear speed thresholds • During transient event, AUTO led blinking
AUTO mode
• 2nd to 4th gear shifting depending on BHL speed thresholds • 2nd gear engaged in AUTO mode @ starting • AUTO to Manual mode switching always available

Electric System : Kick Down
Basic features
Sequential Up & Down shifting (i.e 2nd to 1st, then 1st to 2nd, …) Kick Down function always available, irrespective of shifter position (F, N, R) Kick Down is cancelled shifting the gear selector (1st, 2nd, 3rd, Auto) Kick Down is mantained moving the shifter position (F to N, F to R, …)
Manual mode
AUTO led blinking during Kick Down operation After Kick-down selection, 1st gear is mantained irrespective of vehicle speed
AUTO mode
AUTO led always active Kick Down is cancelled exceeding a programmable speed threshold
