Pull the right shift paddle "+" towards
the steering wheel and release it to enter

"−" paddle the transmission shifts to
"D1 - D2" temporary mode.

Gear Shift Indicator (GSI)
In order to improve fuel economy, we
recommend that you shift gears when
the GSI system prompts you to do so.
This will help reduce fuel consumption
without significantly affecting vehicle
performance.
When in "M" (Manual) or "temporary"
manual mode, GSI indicates when a gear
shift is needed to change gear.
NOTE:
• Pressing R (Reverse) or P (Park) button
when the vehicle is running forward
will display a denial message together
with the R or P letter blinking on the
instrument cluster.
• Pressing "D/M" button when the
vehicle is running rearward will display
a denial message together with the D
or M letter blinking on the instrument
cluster.
GSI indicates when a gear shift is
needed by adding one or two arrows
beside the current gear on the cluster
display.
When the new gear is engaged, the GSI
turns off. If the shift runs late or is not
performed at all, the GSI remains lit for
a few seconds then turns off. As soon
as new conditions requiring further gear
change occur, the GSI will illuminate
again.
Driving and Driver Assistance Systems
NOTE:
The GSI system will only work when the
transmission is set in M (Manual) mode,
except when in CORSA mode.
When in CORSA mode (Trofeo only), a
sport gear SHIFT light will help the driver
understanding when shifting the gear
efficiently.
The graphic is composed by three slots;
when it is completely filled, it suggests
the performance gear shift to the user.
NOTE:
If the automatic transmission is in D
(Drive) mode, the bar will always be
displayed empty.
