Engine control system (EOBD)
The EOBD (European On Board Diagnosis)
system fitted on the vehicle is compliant with the
2003/76B/EC Directive (EURO 4).
This system continuously monitors the
components of the vehicle related to emissions;
it also indicates, when the warning light

illuminates on the instrument panel, that the
components in question are in poor condition.
The objective is the following:
- monitor the system effi ciency
- indicate when a problem causes an
increase in emissions exceeding the limits
established by European regulations
- indicate the need for replacement of worn
components.In addition, the system includes a diagnostics
connector that can be interfaced with suitable
instruments. This makes it possible to read the
error codes stored in the control unit, together
with a set of specific parameters for engine
operation diagnostics.
WARNING: If when turning the ignition key
to MARthe warning light
does not
illuminate or if it illuminates while driving,
contact an Authorised Service Centre of the
Manufacturer’s Network as soon as possible.
WARNING: After correcting the malfunction, the
entire system must be tested by the personnel
of an Authorised Service Centre of the
Manufacturer’s Network that must perform
tests on the bench and, if necessary, the road
test the vehicle: this might require travelling long
distances.
CONSTANT SPEED
REGULATOR (CRUISE CONTROL)GENERAL
The Cruise Control function allows the driver
to maintain the desired vehicle speed constant
without pressing the accelerator pedal. This
reduces driver fatigue on highways, especially
long trips, as the set speed is automatically
maintained.WARNING: The device can only be activated at
speeds exceeding 30 km/h and it deactivates
automatically when the brake pedal is
depressed.

USING THE VEHICLE
RESETTING THE SPEED
STORED IN THE MEMORY
The speed stored in the memory is automatically
zero-reset:
- by turning the engine off
or
- by setting the switch
A to OFF.
CAUTION
When driving with Cruise
Control activated, do not shift to
neutral. It is advisable to activate
Cruise Control only when traffic and
road conditions permit safe use of
this device, that is: on straight and
dry roads, expressways or highways,
smooth-flowing traffic and smooth
asphalt. Do not activate the device in
the city or in heavy traffic.CAUTION
Cruise Control can only be
activated at speeds exceeding 30
km/h.
CAUTION
The device can only be turned
on in 4
th 5th or 6
th gear, depending on
the vehicle speed.
CAUTION
When driving downhill with
the device active, the vehicle may
pick up speed slightly exceeding the
speed stored in the memory due to the
change in engine load.
CAUTION
If the device malfunctions or
fails to operate, set the switch A to
OFF and contact an Authorised Service
Centre of the Manufacturer’s Network
after checking that the protection fuse
has not blown.CAUTION
Switch A can be left on the ON
position at all times, without damaging
the device. In any case, it is advisable
to deactivate the device when it is
not in use. Move switch A to the OFF
position to prevent speeds from being
unintentionally stored.

TRAVELLING
- Caution is the fi rst rule for safe driving.
Being careful also means being in a position
to be able to predict the driving behaviour
of other drivers, that may be wrong or
careless.
- Keep a safe distance from vehicles in front
of you, adjusting this distance in accordance
to the vehicle speed and traffi c conditions.
- Strictly follow the traffi c regulations
applicable in each country and above all,
respect the speed limits.
- Long trips should be started in optimal
physical condition.
CAUTION
Drunk driving, or driving
under the influence of drugs or certain
medicines is extremely dangerous for
the driver and for others.CAUTION
Always fasten the seat belts.
Travelling without your seat belt
fastened increases the risk of serious
injury in the event of a collision.
- Make regular stops to loosen up your limbs
and refresh yourself, and avoid driving for
hours on end.
- Ensure that the air inside the passenger
compartment is changed constantly.
- Never coast downhill with the engine off:
the braking action requires greater effort on
the pedal due to the absence of the engine
brake and the power braking system. DRIVING AT NIGHT
The main guidelines to follow when driving at
night are set out below:
- Drive with the greatest caution: at night the
driving conditions are more demanding.
- Reduce your speed, especially on roads with
no street lights.
- At the fi rst signs of drowsiness, stop: to
continue driving would be a risk for yourself
and for others. Continue only after you have
had a rest.
- Keep the vehicle at a greater distance from
vehicles in front of you than you would
during the day: it is diffi cult to assess the
speed of other vehicles when you can only
see the lights.
- Make sure that the headlights are aimed
correctly: if they are too low, they reduce
visibility and strain the eyes. If they are too
high, they may bother the drivers of other
cars.

134

Sound the vehicle horn rhythmically if you hear
another vehicle approaching.
- When you get out of the vehicle, put on the
high-visibility vest.DRIVING IN THE
MOUNTAINS
On downhill roads, use the engine brake,
engaging low gears so as not to overheat the
brakes.
- Never coast downhill with the engine off or
in neutral, and never with the ignition key
removed.
- Drive at a moderate speed and avoid
“cutting” corners.
- Remember that passing other vehicles when
driving uphill is slower and thus requires
more free distance on the road. If you are
being overtaken on a hill, slow down and
allow the other vehicle to pass. DRIVING ON SNOW OR
ICE
Below is some general advice for driving in these
conditions:
- Keep a very moderate speed.
- Fit snow chains or specifi c tyres if the road
is covered with snow: see the chapters
“Snow chains” and “Winter tyres” in this
section.
- Mainly use the engine brake and avoid
sharp braking.
- We recommend that you activate “Low
grip” mode (see page 122).
- Avoid sudden acceleration and sharp
changes in direction.
- During the winter season, even apparently
dry roads can have icy sections. Be careful
when crossing bridges, viaducts and roads
that have little exposure to the sun and are
bordered by trees and rocks. They may be
icy.
- Keep a safety distance from the vehicles in
front.

USING THE VEHICLE
ANTI-POLLUTION
DEVICES Even if the vehicle is equipped with anti-pollution
devices, the environment deserves the greatest
respect from every one of us.
By following a few simple rules, the vehicle
driver can avoid damaging the environment and
very often can reduce fuel consumption as well.
In this regard, some useful information is listed
here below; please read it carefully.
The correct operation of the anti-pollution devices
not only assures respect for the environment, but
also has an impact on vehicle performance.
So, keeping these devices in good working
conditions is the first rule for driving that is both
ecologically sound and economical.
The first precaution is to follow the Scheduled
Maintenance plan scrupulously. Always use unleaded fuel.
If starting is difficult, do not make prolonged
attempts.
Especially avoid push starts, towing or hill starts:
these are all manoeuvres that can damage
catalytic converters.
Use an auxiliary battery only when making an
emergency start.
While driving, if the engine does not run
smoothly, you may continue driving but reducing
engine performance to a minimum; you should
then contact an Authorised Service Centre
of the Manufacturer’s Network as soon as
possible.
Never run the engine, even if only for testing,
with one or more spark plugs disconnected.
Do not warm up the engine letting it idle before
starting off, except in the event of very low
outside temperatures and, even then, for no
longer than 30 seconds.
CAUTION
During normal operation the
catalyst converter generates high
temperatures. Do not, therefore, park
the vehicle on flammable materials
(e.g. grass, dry leaves, pine needles,
etc.): risk of fire!
Do not install heat guards and do not remove
those already fitted to the catalytic converter and
to the exhaust manifold.
Do not spray anything on the catalytic converter,
lambda probe and exhaust manifold.
CAUTION
Failure to comply with these
rules can lead to fire hazards.

OTHER ADVICE
- Do not warm up the engine when the
vehicle is stationary: in these conditions
the engine heats up much more slowly and
increases fuel consumption and emissions.
It is much better to move off slowly,
avoiding high engine RPM.
- As soon as traffi c conditions and the route
permit it, use a higher gear.
- Avoid depressing the accelerator repeatedly
during stops at traffi c lights or before
turning off the engine.
- Keep your speed as regular as possible,
avoiding unnecessary brake applications
and accelerations, which cause fuel wastage
and strongly increase exhaust emissions.
- Turn the engine off if the vehicle remains
stationary for a long time. - Check the tyre pressure regularly: if the
pressure is too low, fuel consumption
increases and the tyres are damaged.
- Do not transport unnecessary objects in
the luggage compartment. The weight
of the vehicle affects fuel consumption
considerably.
- Use the electrical devices only as long as
necessary. The power required increases
fuel consumption.
PARKINGPull the electric parking brake, straighten the
wheels and turn off the engine.
Never leave the ignition key in position MAR.
Always remove the key when getting out of the
vehicle.
CAUTION
Never leave children
unattended in the vehicle.
CAUTION
Do not park the vehicle on
paper, grass, dry leaves or other
flammable materials. They could catch
fire if they come into contact with hot
parts of the exhaust system.
CAUTION
Do not leave the engine running
with the vehicle unattended.

USING THE VEHICLE
ELECTRIC PARKING
BRAKE
The vehicle is equipped with an automatic
parking brake EPB (Electric Parking Brake).
It is automatically engaged when the engine
is turned off and it is disengaged when, with
the engine running, the accelerator pedal is
depressed.
When the electric parking brake is engaged and
the key is turned to STOP, the warning light

illuminates on the instrument panel.During engagement and disengagement, the
warning light
flashes until the maximum
engagement force and full release have been
reached.
In the above conditions, the automatic activation
function can be deactivated/activated by
pressing the button A on the dashboard.
CAUTION
During engagement or
disengagement of the electric parking
brake, always hold the brake pedal
depressed.

138

B
Engagement
The electric parking brake is automatically
applied when the engine is turned off and the
vehicle is stationary.
It can only be disengaged when the engine is
restarted.
When the key is removed or set to STOP it
cannot be disengaged.
The electric parking brake can also be manually
engaged when the vehicle is moving or the key is
turned to MAR by pulling up the lever
B.
If the engine was turned off with the automatic
engagement device deactivated, you can
reactivated it simply by pulling lever B.
CAUTION
Always check that the vehicle is
actually locked before leaving it.
CAUTION
When the EPB button is
activated while driving, the vehicle
slows down with strong deceleration
(Dynamic Braking). It is therefore
advisable to use this function only
in case of an emergency. The vehicle
stability is in any case ensured by the
VDC system, which is always active.
Disengagement
The parking brake automatically disengages
when the accelerator pedal is depressed.
The electric parking brake can also be manually
disengaged when the vehicle is moving or the
key is in position MAR by manually pulling up
lever
B and simultaneously depressing the brake
pedal.
WARNING: In certain conditions it is however
advisable to manually disengage the electric
parking brake and brake the starting manoeuvre
slightly using the service brake. This is advisable
when there are obstacles very close to the
vehicle in the direction in which you intend to
move.
