UP-shifting
Use the right-hand UP paddle without releasing the accelerator
pedal.
An UP-shift request is not accepted when engagement of the
requested gear forces the engine to underrev or if an UP-shift is
already in progress because of engine overrevving.
In any event, it is advisable to:
• Shift gears without releasing the accelerator pedal if pressed.
• Wait until gearshifting has been completed before requesting the
next shift, avoiding a rapid sequence of multiple requests.
UP-shifting due to overrevving
The system "automatically" engages a higher gear if the accelerator
pedal is pressed and the engine approaches the "runaway speed rate"
(overrevving).
Important note
This will not occur when the system is in "RACE", "CT OFF" and
"CST OFF" driving mode.

DOWN-shifting
Use the left-hand DOWN paddle without releasing the accelerator
pedal.
A DOWN-shift request is not accepted if engagement of the
requested gear forces the engine beyond a certain RPM, depending
on the gear requested, or if a DOWN-shift is already in progress
because of engine underrevving.
In any event, it is advisable to:
• Shift gears without releasing the accelerator pedal if pressed.
• If DOWN-shifting is requested to start overtaking which requires
quick acceleration, press the accelerator pedal just before using
the paddle.
• Wait until gearshifting has been completed before requesting the
next shift, avoiding a rapid sequence of multiple requests.
DOWN-shifting due to underrevving
• The system shifts down "automatically" if the engine goes below a
minimum number of revs (1250 RPM).
• The DOWN-shift request from the paddle is ignored if
gearshifting is already in progress due to engine underrevving.
Sequential downshifting
During deceleration, with the brake pedal pressed and the ABS
system disabled, sequential downshifting can be performed by
holding the left-hand "DOWN" paddle down.
The sequential gearshifting request is accepted until the second gear
is engaged.
This system is only activated when the "Manettino" is set to SPORT,
RACE, CT OFF or CST OFF.
