Manual�mode/sequential�mode
The�gears�can�be�shifted�manually�at�the�appropriate�road�speed�and�engine�revs�by�means�of� "+"
and �"–" �gearshift�paddles�on�the�steering�wheel�or�by�moving�the�gear�selector�lever� "forward" �or
"back" .�The�selected�gear�is�maintained�even�when�the�engine�speed�limitation�is�reached,�but�an
automatic�downshift�is�performed�when�the�vehicle�drops�below�the�gear-specific�minimum�driving
speed.
When�manual�mode�is�selected�for�the�first�time�after�a�change�of�terminal�status�(engine�restart),�the
last�Drivelogic�level�used�is�active.
Three�driving�programs�are�also�available�here�for�selection:
1:�Comfortable,�smooth�gearshifts�in�all�driving�conditions
2:�Sporty,�fast�gearshifts,�light�gearshift�jolts�permitted�at�higher�engine�loads�and�speeds
3:�Maximum�sporty�shift�speed�and�gearshifts�are�the�requirement�for�the�activation�of�Launch�Control.
Using�the�highest�program,�i.e.�3,�does�not�require�the�M�DSC�to�be�deactivated.
