Start the engine by pressing the start button (see 
page 114).
Press the Fix&Go button 
E at position “I”. The 
electric compressor will activate and the liquid 
with air will inflate the tyre.
A pressure of at least 1.8 bar (26 psi) should 
be reached within 20 minutes. If this does not 
occur, turn off and remove the Fix&Go kit.
Move the vehicle forward and backward by 10 
metres to better distribute the sealant in the tyre.Attach the quick-connector of the compressor 
directly on the tyre valve and repeat the inflation 
procedure.
If the minimum tyre pressure is not reached, 
do not start the vehicle. Contact an Authorised 
Service Centre of the Manufacturer’s 
Network.
When the correct pressure has been reached, 
move the vehicle forward and backward to 
evenly distribute the sealant in the tyre.
After 10 minutes, stop and check the tyre 
pressure. If the pressure is below 1.3 bar 
(19 psi), do not drive the vehicle. The tyre is 
excessively damaged. Contact an Authorised Service Centre of the 
Manufacturer’s Network.
If the pressure is equal to or greater than 1.3 
bar (19 psi), repeat the inflation procedure until 
reaching the adequate tyre pressure and resume 
driving.
Remove the warning label 
F from the bottle and 
position it on the dashboard as a reminder to 
the driver that the tyre has been treated with 
automatic Fix&Go.

FUELOnly use unleaded premium fuel with an octane 
number (R.O.N.) of no less than 95.
Tank capacity: approx. 86 litres, including a 14 
litre reserve.WARNING: The anti-pollution devices of the 
vehicle require unleaded fuel to be used at 
all times. Under no circumstance, not even in 
emergency situations, should leaded fuel be 
supplied to the fuel tank, not even a minimum 
quantity. You would irreparably damage the 
catalytic muffler. 
WARNING: An inefficient catalytic muffler results 
in noxious exhaust emissions which are harmful 
for the environment.
ENGINE OILTo check the level, please consult the 
“Maintenance” section. 
Do not top up with oil having characteristics other 
than those of the oil already used.

BRAKE FLUID 
Check that the fluid level in the tank is at the 
maximum level. If the level goes below the 
minimum, with the ignition key in position MAR, 
the relative warning light 
 will illuminate on 
the instrument panel.
If fluid is needed for topping up, use only the 
type classified as DOT4.
WARNING: The brake fluid is hygroscopic (i.e. 
it absorbs humidity). For this reason, if the 
vehicle is used mainly in areas with a high rate 
of atmospheric humidity, the fluid should be 
changed more frequently than indicated in the 
Maintenance Schedule. 
WARNING: Do not let the brake fluid, which 
is highly corrosive, come into contact with the 
paintwork. If this should happen, wash the 
paintwork immediately with water. 
WARNING: The symbol 
 on the container 
identifies the synthetic type of brake fluid, 
distinguishing it from the mineral type. Using 
mineral fluids irreparably damages the special

MAINTENANCE
WARNING: If the battery charge remains 
below 50% for a long period of time, it will be 
damaged due to sulphating: this will reduce its 
performance and starting power and the battery 
will be more subject to freezing (this can happen 
even at -10°C).We recommend that you have the battery charge 
condition checked, preferably at the beginning of 
the cold season, to prevent the electrolyte from 
freezing. 
This check should be performed more frequently 
if the vehicle is used mainly for short trips or if it 
is equipped with power absorbing devices that 
remain permanently on even if when the ignition 
key is removed. This applies above all if these 
devices have been fitted “after market”. 
If the vehicle is not used for long periods of time, 
please refer to chapter “If the vehicle is laid up 
for long periods”, in this section.WARNING: If additional systems have to be 
fitted in the vehicle, there is the risk of creating 
dangerous branches on the electric wiring, in 
particular if the safety devices are involved. 
ELECTRONIC 
CONTROL UNITSNo special precautions are required for the 
normal use of the vehicle. 
In the event of repairs to the electrical system 
or in an emergency starting, the following 
instructions must be strictly followed:
-  Never disconnect the battery from the 
electrical system when the engine is 
running. 
-  Disconnect the battery from the electrical 
system when recharging it (see page 168 
“If the battery is fl at”). WARNING: When the battery is disconnected, 
you must first detach the negative pole terminal 
(–) and then the positive pole one (+).
WARNING: The battery is secured inside the 
vehicle by means of a metal box, therefore, be 
extremely careful not to let the battery charger 
clips come into contact with it.WARNING: When the battery is reconnected, 
you must first attach the positive pole (+), 
remembering to cover it with the cap provided, 
and then the negative one (–).
-  Never perform the emergency starting 
procedure using a battery charger: always 
use an auxiliary battery. 
-  Take special care when connecting the 
battery to the electrical system, checking 
both that polarity is correct and that the 
connection is properly working. 
-  Do not connect or disconnect the terminals 
of the ECUs when the ignition key is at 
MAR.
-  Do not check the electric polarities through 
sparking. 
-  Disconnect the ECUs in the event of 
electrical welding on the vehicle body. 
Remove them if the temperature is 
over 80°C (special interventions on the 
bodywork, etc.).
