To facilitate reading and fast consultation, the
topics have been divided into sections and
chapters.
The important parts requiring particular attention
are easily identifi able in the sections and

A
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.
The amber colour warning light
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.

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.

OTHER SYSTEM
FUNCTIONS
“Low-grip” WET mode
This mode can be used on particularly slippery
road surfaces (e.g., snow, ice) and it is
activated/deactivated by pressing button
E.
This will light up the letter “W” on the instrument
panel display.
While driving, the system ignores any
gearshifting which would cause RPM adjustment
above 2800 RPM.
“Low-grip” mode has priority over the other
functions (“automatic gearshift” and “SPORT”)
and it assists the VDC system.It is always a good rule to deactivate the other
operating modes (“automatic gearshift” and
“SPORT”) before you select “low-grip” mode.
“Automatic gearshift” mode AUTO
It is activated/deactivated by pressing the
button
D; the gear displayed is replaced with the
letter “D” and the system will automatically shift
the gears UP and DOWN according to the vehicle
speed, the engine RPM and the torque/power
requested by the driver.
WARNING: The “automatic gearshift” mode has
priority over “SPORT” mode. Therefore, if you
press the AUTO button, D the system will operate
in “automatic gearshift” mode.You can go back to NORMAL mode (or SPORT
mode, if this was active) by holding the button
D
pressed down until the word AUTO goes off.When the vehicle is stationary, requesting N 1
st
or R will not cause the system to switch from
“Automatic gearshift” to “Normal” mode.
It is always a good rule to deactivate the other
operating modes before you select “Automatic
gearshift” mode.
“No auto exit” strategy
In AUTO mode you can always request
a gearshift using the paddles, which will
temporarily set the system to “manual” mode.
This is shown on the display by the word “AUTO”
that flashes for 5 seconds and then illuminates
permanently, thus confirming that the system
has returned to AUTO mode. A further gearshift
request will restart the 5-second timer.

CAUTION
During the tyre life, the rolling
direction of the first fitting shall
always be observed, also in case of
“non-directional” tyres.
CAUTION
Check the depth of the tyre
tread at regular intervals (minimum
allowed value 1.6 mm). The thinner
is the tread, the greater is the risk of
skidding.
CAUTION
Drive carefully on wet roads to
decrease the risk of aquaplaning.
WINDSCREEN
WIPERSClean the rubber parts regularly using the
appropriate products.
Change the blades if the edge of the rubber
is deformed or worn. In any case, the blades
should be changed about once a year.
CAUTION
Travelling with worn wiper
blades is very dangerous because it
reduces the visibility in the event of
poor atmospheric conditions.
CAUTION
The arms of the wiper blade
have to be replaced with new ones
after having disassembled them twice.
The special arm fixing system ensures
optimal mechanical stability only after
the first two refitting operations,
provided that the specified tightening
torque is observed.CAUTION
We advise you to have any
operations involving removal of the
windscreen wiper arms performed at
an Authorised Service Centre of the
Manufacturer’s Network.
Some simple measures may reduce the
possibility of damage to the blades.
- In the case of temperatures below zero °C,
check that ice has not stuck the rubber part
against the windscreen glass. If necessary,
release with an anti-ice product.
- Remove any snow on the windscreen: as
well as protecting the blades, this avoids
forcing and overheating the electric motor.
- Do not activate the windscreen wipers when
the windscreen is dry.
