Sport Skyhook Suspension
(for versions/markets,
where provided) The electronic system controlling the
vehicle suspension uses the
sophisticated on board sensors and is
aimed at optimizing vehicle
performance.
The system is capable of constantly
monitoring suspension damping by
means of the actuator fitted on each
shock absorber (Skyhook type). This
way, the shock absorber setting is
suited to the road surface conditions
and vehicle dynamics, thus improving
passenger comfort and road-holding.
By pressing button “SPORT” on the
central console, the driver can choose,
even while driving, a normal or
dynamic-type setting for the
suspension, depending on their own
driving style. This way, the system operates with a
shock absorber “softer” setting in
NORMAL drive mode, and a “harder”
setting if SPORT drive mode is selected
(see “Drive Mode” in section
“Driving”).
The strategy used by the system
controlling suspension damping is
aimed at reducing the vertical
oscillations of the vehicle (rolling and
pitching) to a minimum.
The activation of SPORT drive mode
sets the suspension for sports-style
driving and acts on the ASR and
gearbox systems as well, modifying
their setting for dynamic-style driving.
System Components
The system is controlled by an ECU
which manages the solenoid valves on
each shock absorber in response to the
sensor signals, thus adjusting
suspension damping and setting. The sensors which enable the ECU to
calculate the vehicle speed, vertical
and side acceleration, as well as the
instantaneous braking system
pressure, thereby controlling
suspension damping, are the
following:
• front left-hand vertical acceleration
sensor;
• front right-hand vertical acceleration
sensor;
• rear vertical acceleration sensor;
• front left-hand wheel acceleration
sensor;
• front right-hand wheel acceleration
sensor;
• lateral acceleration sensor;
• driving speed sensor;
• brake pedal switch.
Self-diagnostics Whenever the engine is started, the
system performs a self-diagnostic
cycle. If a malfunction is found, the
amber warning light is displayed
accompanied by the message “Check
suspensions” (see paragraph
"Malfunction Indicators" in this
chapter).Understanding the Vehicle

Sequential manual operation can only
be selected from the D (Drive) position
whatever the function (SPORT,
NORMAL) active at the time of the
request. The gear selected by the
automatic transmission will remain
engaged when the transmission shift
lever is moved.
Shifting the lever back to D (Drive),
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 transmission ECU will select
automatic operation.
Gearshift Paddles Operation
In sequential manual operating mode
(MANUAL), upshifting and
downshifting can be controlled not
only with the transmission shift lever
but also with the two paddles
positioned behind the steering wheel.
"+": (UP): upper gearshift paddle.
"–": (DOWN): lower gearshift paddle. Also in automatic transmission mode,
when the transmission lever is in
position D (Drive), you can shift to a
different gear by moving one of the
paddles. This action will temporarily
switch the system to sequential
manual operation.
If you then keep to a constant driving
style (low longitudinal and lateral
acceleration), the gearbox
automatically switches back to
automatic operation.
Gear Shift Indicator Light
In order to improve fuel economy, we
recommend that you shift gears when
the system prompts you to do so. This
will help reduce fuel consumption
without significantly affecting vehicle
performance.
The arrow icon beside the displayed
gear will light up to indicate the
moment the gear change is required. This indicator lights up just before
reaching the required speed for gear
change.
When the new gear is engaged, the
indicator turns off. If the shift runs
late or is not performed at all, the
indicator remains lit for a few seconds
then turns off. As soon as new
conditions requiring further gear
change occur, the indicator light will
illuminate again.
NOTE:
The gearshift indicator will only work
when the transmission is set to manual
sequential operation (see paragraph
"Sequential Manual Operation
(MANUAL)" in this chapter). Driving
