Engine malfunction alarm devices
If the warning light "Engine check system
failure" flashes or remains on fixed while
the engine is running, it indicates that the
engine or the emission control system may
be malfunctioning.
The electronic system detects and isolates
the error, preventing damage to the engine
or the production of noxious emissions.
When the warning light "Engine
check system failure" comes on,
engine performance may also considerably
be reduced.
Drive carefully, avoiding sudden
acceleration and high speeds.

Clutch

The clutch is of the dry double-plate type,
with elastic hub and diaphragm spring; its
disengagement is controlled by a self-
adjusting hydraulic thrust bearing.
Clutch fluid tank
The tank is positioned in the front
compartment and is shared with the brake
system in the mechanical gearbox version.

Gearbox

The gearbox has 6 synchronised gears plus
reverse gear.
The gears are quick-coupling, with reduced
stroke.
The synchronisers are of the double and
triple cone type.
The gearbox also contains the bevel gear
pair and the electronic differential.

Electronic differential (E-DIFF)

The vehicle is equipped with an electronic
differential, working on the rear axle, which
continually runs a variable check on the
locking between the two axle shafts.
The electronic differential system enhances:
- performance
- directional stability of the vehicle
- active safety even at the limit of grip
- driving comfort and handling.
Operation is based on the analysis and
forecast of the vehicle performance in
all possible conditions. This is done by
continually monitoring the pressure of the
clutch actuator on the differential.
The input signals are the dynamic
parameters of the vehicle, that the control
system translates into a torque difference
between the two driving wheels.
