Maserati GRANCABRIO Owner's Manual page 154

WARNING: However, some conditions
will remain automatically controlled,
for example, when the engine is
overrevving or underrevving, the
system automatically engages a
higher or lower gear.
WARNING: If you request a gearshift
in conditions where the engine is
overrevving or underrevving, the
system will not accept the command.
WARNING: The ECU is programmed
to control one gearshift at a time,
therefore, fast and repeated actions
will not necessarily result in a
gearshift. A higher or lower gear
5
is engaged only if the previous
procedure requested has been
completed.
When the system refuses to engage a
gear, an acoustic signal will sound for
a few seconds.
Sequential manual operation can
only be selected from the D position
whatever the function (SPORT,
NORMAL) active at the time of the
request.
152
The gear selected by the automatic
gearbox will remain engaged when
the lever A is moved.
Shifting the lever back to D,
automatic operation will instantly be
resumed, and a gear will be engaged
based on the driving style and mode
selected.
In the event of a failure of the
sequential manual gearshift system,
the gearbox ECU will select automatic
operation.
Other system functions
The settings automatically selected by
the system operate in three modes:
- NORMAL;
- SPORT;
- ICE (Low Grip).
Activate the desired mode by pressing
the relative button.
The active mode is shown on the
instrument panel display.
For each mode there are various
vehicle settings, that are automatically
set by the system in relation to
the travelling speed, engine RPM,
accelerator position, speed with which
the pedal is depressed as well as the
travelling conditions (uphill, downhill,
curves).
NORMAL
This mode is intended specifi cally
for comfortable and fuel-economy
driving (low longitudinal and lateral
acceleration); the gears are shifted
with minimum rpm in lowest noise
(gears are shifted at low engine
speeds).
