Hot-mode strategy
In the event that the engine oil or
coolant temperature is too high or
both, the gearbox system reduces the
maximum engine speed to 4000 RPM.
Therefore, upshifting will occur at this
limit.
This strategy does not apply to
downhill driving, so as to always
have the effi ciency of engine braking
together with the standard braking
system.
ESC system operations
In order to prevent unstable driving
conditions, the ESC system may
request the gearbox system to
deactivate gearshifting. The system
handles this request depending on
the gear engaged and on the RPM,
and decides whether to accept it or
not.
Cruise Control
With the Cruise Control function, the
gearbox system selects such settings
as to provide enhanced comfort and
fuel-economy.
MC Start Strategy (only for
GranCabrio SPORT)
With the aim of optimising standing
starts for performance driving (only
recommended for use in areas closed
to traffi c and in accordance with
the Highway Code), the automatic
gearbox system is equipped with
quick start strategy.
This strategy is activated when
the following conditions occur
simultaneously:
- AUTO and SPORT modes active;
- ESC mode OFF;
- brake pedal depressed.
In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
RPM. and then, upon releasing the
brake pedal, have the best standing
start performance.
This strategy must only
be used on vehicles in
areas closed to traffi c, in
accordance with the Highway Code
and only by skilled drivers.
Malfunction indication
The malfunctions indicated are
attributable to two causes:
- gearbox failure;
- gearbox oil temperature too high.
In both cases, the warning light
comes on. In the fi rst case, it
is accompanied by the following
message on the display: "Check
transmission go to dealer" in the
second case: "High gearbox oil
temperature".
Gearbox failure
This message indicates a gearbox
system malfunction, therefore, if you
are driving, the ECU that controls the
device sets an emergency program.
WARNING: In these conditions, we
recommended that you stop the
vehicle and turn off the engine for
at least one minute. When restarting
the engine, the autodiagnostic system
may cancel the malfunction, which
will in any case be recorded by the
ECU.
In failure conditions, the gearshift
lever A can however be shifted to R,
N and D.
When shifting to D, only a few gears
will be available, depending on the
malfunction found.
