Electronic automatic gearbox
157
+ / - – Sequential manual
operation (MANUAL)
This allows you to manually engage
gears while driving.
When the automatic gearshift mode is
selected (position D), shift the
gearshift lever A to + or -.
When this mode is selected, the symbol
+ or – illuminates on the gear display E,
based on the position of the gearshift
lever, and the gear engaged is shown
on the instrument panel display.
When sequential manual
operation is selected,
upshifting or downshifting
must be performed manually.
To engage the gears, shift the gearshift
lever A to one of the following two
positions:
+ UP to engage a higher gear
- DOWN to engage a lower gear.
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 electronic control unit
is programmed to handle one
gearshift at a time, therefore, fast and
repeated requests will not necessarily
result in a gearshift.
The higher or lower gear is engaged
only if the previous gearshift
procedure has been completed.
When the system refuses to engage a
gear, an acoustic signal is sounded for
a few seconds.
Sequential manual gearshift mode can
only be selected from position D,
whatever the driving mode (SPORT,
NORMAL) active upon requesting a
gearshift.
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
traveling speed, engine RPM,
accelerator position, speed with which
the pedal is depressed as well as the
traveling conditions (e.g., uphill,
downhill, on curves).
NORMAL
NORMAL mode is the default setting
when the engine is started.
This mode is intended specifically for
comfortable and fuel-economy driving
(low longitudinal and lateral
acceleration); the gears are shifted
with minimum vibration in lowest
noise (gearshifting at low engine
RPM).
