INSTRUMENTS AND CONTROLS
TRIP COMPUTER
General
When the electronic key is inserted in the ignition
block, the “Trip computer” allows you to view
the vehicle mileage features. This function
comprises the “Trip A” function which monitors
total mileage, and the “Trip B” function which
monitors trip mileage; the latter function is
“contained” in the total mileage function.
Both functions can be reset (reset when setting
off on a new trip).
Trip A and B allow you to view the following
values:
- Fuel range
- Distance travelled
- Average fuel consumption
- Instantaneous fuel consumption
- Average speed
- Travel timeValues displayed
Fuel rangeIt indicates the distance you can still travel with
the fuel left in the tank, assuming you continue
travelling at the same speed.
A specific message will be shown on the display
“----“ when the following events occur:
- when the fuel range is less than 50 km (or
30 mi)
- if the vehicle is stopped with the engine
running for more than 3 minutes.
Distance travelledIt indicates the distance travelled from the
beginning of a new trip.
Every time the battery is connected and at the
beginning of each new trip (reset) the display
indicates the value “0.0”.WARNING: If there is no information, all the
Trip Computer indicators will show “-” instead of
the value. When correct operation is resumed,
the counter resumes regular operation as well,
without resetting the values displayed prior to
the malfunction nor restarting the count from
zero as for a new trip.Average fuel consumptionThis is the average fuel consumption from the
beginning of a new trip.

INSTRUMENTS AND CONTROLSWARNING: When the ignition key is turned to
MAR, if the warning light does not illuminate
or if it illuminates while driving, immediately
contact an Authorised Service Centre of the
Manufacturer’s Network.
Excessive coolant temperature
(*)
Combined with the “Coolant
thermometer”, it illuminates together with
the warning light on the instrument panel
and indicates an excessive temperature of the
coolant.
In this condition, stop the vehicle and have
the cooling system checked by an Authorised
Service Centre of the Manufacturer’s
Network. INDICATORS AND
WARNING LIGHTS
Rear fog lights
When the rear fog lights are turned
on.
Position lights / low beams
Illuminates when the position lights
or low beams are activated.
High beams
When the high beams are turned on
or used to flash.
Low beams
Illuminates when the low beams are
activated.
Low fuel
When this warning light illuminates,
it means that there are about 14
litres of fuel left in the tank.Engine failure control system
(EOBD)
In normal conditions, this warning
light should illuminate when the ignition key is
turned to MAR and go off as soon as the engine
is started. This will show that the warning light is
working properly.
If the warning light remains on or illuminates
while driving, it indicates that there is a failure
in the fuel supply/ignition and emission control
system. This failure could cause high exhaust
emissions, loss of performance, poor vehicle
handling and high consumption levels.
In these conditions you can proceed slowly
without demanding engine performance.
Prolonged use of the vehicle when the warning
light is on can cause damage. Therefore, as
soon as possible contact an Authorised Service
Centre of the Manufacturer’s Network.
The warning light will go out if the problem
disappears. The error will be stored in any case.

STARTING THE
ENGINE
CAUTION
Hold the brake pedal depressed
when starting the engine.
CAUTION
It is dangerous to operate the
engine in an enclosed space. The engine
consumes oxygen and discharges
carbon dioxide, carbon monoxide and
other toxic gases.
WARNING: Before start-up, switch off the
electrical devices with a high power consumption
(air-conditioning and heating system, heated
rear window, headlights, etc.).
WARNING: Do not start the engine if the fuel
level in the tank is low.
1) Make sure that the parking brake is applied
and that the doors are closed.
2) Hold the brake pedal depressed when
starting the engine.
3) Do not depress the accelerator pedal.
4) Set the gear to neutral by pulling both
paddles UP and DOWN towards the
steering wheel and check that the gear
display indicates N not fl ashing.
5) Turn the ignition key to MAR.
6) press button START button and release it as
soon as the engine starts.
Do not hold the START button for a long time.If the engine does not start, turn the key back to
position STOP and wait for the gear display to go
off before retrying.
The engine can also be started with a gear
engaged; turning the key to position MAR, with
the brake pedal depressed, press the START
button. The system allows the clutch to open and
the gearshift to engage neutral gear; then the
starter motor receives clearance for start-up. This
procedure usually requires one second. At very
low temperatures, the procedure could take a
slightly longer time.
If the gearbox is instead in the N position,
starting is immediate.
If the engine does not start after turning the key
to position STOP, wait for the gear display to go
off and then repeat the entire procedure.

WARNING: Do not use a battery-charger for
emergency starting under any circumstances:
you could damage the electronic systems,
particularly the control units that manage the
ignition and fuel supply functions.
CAUTION
Remember that when the
engine is not started, the power
braking and power steering systems
are not activated and so the effort
required on the brake pedal and
steering wheel is much greater.
TURNING OFF THE
ENGINE
With the engine idling, rotate the ignition key to
the STOP position.
A burst on the accelerator pedal before turning
off the engine has no purpose and increases fuel
consumption.
Q-SELECT
GEARBOXThe “Q-Select gearbox” is controlled with
the paddles on the steering wheel for gear
engagement and with the buttons on the centre
console for reverse gear engagement and
activation of the “automatic gearshift” and “low
grip” functions.
The “Q-Select gearbox” controls are the
following:A - Lower gear engagement paddle DOWNB - Upper gear engagement paddle UPC - Reverse gear engagement button

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.
