ACTIVE AND PASSIVE SAFETY
VDC SYSTEMThe vehicle is equipped with the anti-yawing
control system VDC (Vehicle Dynamics Control)
which incorporates all the control systems: ABS,
EBD, ASR and MSR. This system is equipped
with a model that predicts the vehicle behaviour
with great accuracy. The system is capable of
detecting whether the driver is about to lose
control of the vehicle. In this case, it can activate
the brake calipers individually and engine
control, in order to create a torque sufficient to
resist the vehicle yawing moment.ACTIVATION
The VDC and ASR systems are integrated in one
single function and are automatically activated
every time the engine is started; they can be
deactivated by pressing the button
A for about
1 second. Press the button
A again to reactivate
the systems.

on the
instrument panel flashes during all the operating
phases.FAILURE SIGNALS
In the event of a malfunction, the system
is automatically disabled and cannot be
reactivated. This condition is signalled while
driving by the amber warning light on the
instrument panel that illuminates together with
the message “VDC failure - Go to workshop”.
When the engine is started, the system
malfunction is indicated by the illumination of
the warning light .
WARNING: In the event of a malfunction
and with the VDC deactivated, the vehicle
behaves as if it were not equipped with this
system: however, we recommend that you
contact an Authorised Service Centre of the
Manufacturer’s Network to have the system
checked.

WARNING: If you have to tow the vehicle with
2 wheels raised, ensure that the ignition key
is in the STOP position. Otherwise, with VDC
activated, the relative control unit will store a
malfunction, resulting in the illumination of the
warning lights
on the instrument panel and
on the display: this requires the intervention
of an Authorised Service Centre of the
Manufacturer’s Network to correct the system
malfunction.
WARNING: In low- and medium-grip conditions
(e.g., rain, snow, ice, sand, etc.) it is advisable
not to use SPORT mode, even with the VDC
activated.
WARNING: Driving on parabolic curves will
deactivate the system.
ASR SYSTEM (ELECTRONIC ANTI-
SKID DEVICE)The ASR system avoids driving wheels skidding
during acceleration through the engine control
unit (spark advance delay, engine throttle
opening reduction and fuel injection cut) and the
rear brakes.
The action of the ASR system enhances vehicle
stability and improves active safety while driving,
specially under the following conditions:
inside wheel skidding when cornering due
to dynamic load variations or excessive
acceleration
excessive power transmitted to the
wheels, also in relation to the road surface
conditions acceleration on slippery, snow-covered or icy
roads
grip loss on wet road surface
(aquaplaning).
In normal conditions (SPORT mode off), the ASR
system increases stability in low and medium
grip conditions, while with SPORT mode active
the system favours traction, thereby optimising
vehicle performance on dry asphalt.

In the event of a malfunction, the system
is automatically disabled and cannot be
reactivated. This condition is signalled while
driving by the amber symbol
on the display
that illuminates together with the message “ASR
failure - Go to workshop”.
MSR FUNCTION (ENGINE
BRAKING TORQUE
ADJUSTMENT)
The ASR system also controls the engine braking
torque when the accelerator pedal is released
under low grip conditions (e.g., snow, ice etc.):
in these conditions, the high braking torque of
the engine may cause instability of the vehicle.The system, using the same sensors as the ABS
system, detects the skidding of one or both
of the driving wheels when the accelerator is
released and opens the motor-driven throttle for
the engine fuel system. This reduces the braking
torque and resets the maximum grip conditions
for the driving wheels.
WARNING: However, the maximum deceleration
that can be obtained with the engine brake still
depends on the tyre grip on the road. Snow or ice
obviously reduce grip values.

ABS AND EBD
SYSTEMSThe vehicle is equipped with ABS (Anti-lock
Brake System) and EBD (Electronic Brake force
Distribution) system which enhances braking
power through the ABS system sensors and
control unit.
In the event of an emergency stop or braking on
slippery surfaces (e.g., snow, ice etc.) the ABS,
together with the standard braking system, is
designed to allow the driver to apply maximum
braking force without causing the wheels to lock
and consequently losing control of the vehicle.
The system is based on an electronic control unit
that processes the signals coming from 4 sensors
fitted on the 4 wheels.
When a wheel tends to lock, the sensor warns
the control unit, which informs the electro-
hydraulic unit so that it controls the pressure
exerted on the brake calipers; the driver feels a
“pulsating” sensation on the brake pedal which
is completely normal.
In the event of a failure, the system will be
deactivated, but this will not affect the efficiency of the standard braking system.
The failure is signalled by the amber warning
light
on the instrument panel and the
display which illuminates together with the
message “ABS failure - Go to workshop”.
In this case, we recommend that you contact the
nearest Service Centre of the Manufacturer’s
Network in order to identify the fault as soon as
possible, by means of the system self-diagnostic
function.CAUTION
The vehicles must be equipped
only with wheels, tyres and brake
pads of the type and make approved
by the Manufacturer for this model.CAUTION
Regardless of the fact that
this device makes a considerable
contribution to safety it is still
essential to drive with the greatest
care when the road surface is wet,
covered with snow or ice.
CAUTION
The vehicle is equipped with
Electronic Brake force Distribution
(EBD). The warning light

illuminates when the engine is running
to indicate an EBD system malfunction.
In this case, sharp braking can cause
early locking of the rear wheels
and possible side skidding. Driving
extremely carefully, immediately go
to the nearest Service Centre of the
Manufacturer’s Network to have the
system checked.

ACTIVE AND PASSIVE SAFETY
CAUTION
The warning light
usually
comes on with running engine to
indicate a fault in the ABS system only.
In this case, the standard braking
system is still efficient, but cannot use
the ABS system. In these conditions,
also the EBD system efficiency may be
reduced. Drive with the greatest care
to avoid abrupt braking and go the
nearest Service Centre of the
Manufacturer’s Network to have the
system checked-
CAUTION
If the low brake fluid warning
light
illuminates while driving,
stop the vehicle and check the brake
fluid level immediately. If the level is
below the minimum notch, top up with
the recommended oil and immediately
contact an Authorised Service Centre
of the Manufacturer’s Network to
have the system checked.
Brake fluid leaks impair the operation
of the braking systems, both of the
traditional type and of those equipped
with ABS.
CAUTION
System performance in terms
of active safety is not a reason for the
driver to run unnecessary risks. The
driving style shall always be suited to
weather conditions, range of visibility
and traffic.CAUTION
The maximum obtainable
deceleration always depends on the
tyre grip on the road surface. With
snow or ice the grip is obviously
reduced and the braking distance is
very high, even with the ABS system.

FUEL CUT-OUT
INERTIA SWITCHThe vehicle is equipped with a safety switch
which activates in the event of a collision, cutting
off the fuel supply and consequently causing the
engine to stop. It also prevents fuel leaks if the
fuel lines are damaged during the accident.
Activation of the safety switch is signalled by
the illumination of the warning light
on the
display.
The switch is positioned underneath the front left-
hand seat. Move the seat fully back to access it.
CAUTION
After impact, if you smell fuel
or note any leakage from the fuel
supply system, do not reactivate the
switch in order to prevent any fire
risks.
The activation of the inertia switch causes all the
doors and the luggage compartment to unlock
and in the internal dome light and the four
direction indicators to turn on.
RESETTING THE SWITCH
Turn the ignition key to position STOP.
Check that there is no leakage from the fuel
system.
If no leaks are found, reset the inertia switch
which stops the fuel pump operation, by pressing
button
A on the switch.
Turn the ignition key to position MAR, wait a few
seconds and press the START button.Check that the warning light
on the display
is off.
Check once again that there are no fuel leaks.
