CHECKING
FLUID LEVELS
Be careful not to mix up
the various types of fluids
when you are topping up:
they are mutually incompatible
and could damage the vehicle.
Do not smoke while work-
ing in the engine compart-
ment: the presence of flammable
gas and vapour could cause a fire.
WARNING
Scarves, ties and other
loose articles of clothing
could easily get caught up in mov-
ing parts. This can be extremely
dangerous for the wearer.
WARNING

169VEHICLE MAINTENANCE
Do not add oil with dif-
ferent specifications from
the oil already in the en-
gine.

versions
Check engine oil with the vehicle on
level ground and while the engine is
still warm (approximately 10 minutes
after stopping the engine). The oil
level should be included between the
MINand MAXreference lines on
the dipstick.
The gap between MINand MAX
reference lines corresponds to ap-
proximately 2 litres oil.
The oil level must never exceed the
MAXline.If the oil level is near or even below
the MINline, pour in oil through the
filler hole until it reaches the MAX
line.

Be very careful under the
bonnet: you risk burning
yourself. Remember that when the
engine is hot, the fan can start up
and cause injuries.
WARNINGIMPORTANT After topping up or
changing the oil, let the engine turn
for a few seconds and wait a few min-
utes after stopping it before you check
the level.

170VEHICLE MAINTENANCE
Engine oil consumption
Maximum engine oil consumption is
approx. 450 grams every 1000 Km.
During the beginning of the vehicle’s
life the engine is tuning in. Engine oil
consumption can only be considered
stabilised after the first 5,000 - 6,000
km.
IMPORTANTEngine oil consump-
tion depends on the conditions the ve-
hicle is being used in.ENGINE COOLANT
Check coolant level when the engine
is cold. The level should be included
between the MIN and MAXrefer-
ence lines on the reservoir.
If the level is low, loosen the expan-
sion tank cap A-fig. 9and top up
slowly through the filler with the flu-
id specified in “Fluids and lubricants”
table in section “Technical Specifica-tions”, until the level approaches the
MAX line; contact Fiat Dealership
for this operation.
Coolant mixture gives freeze pro-
tection to – 40°C.
Used engine oil and re-
placed oil filters contain
substances which can
harm the environment. We rec-
ommend you have the vehicle
seen at a Fiat Dealership for the
oil and filter change. It is suitably
equipped for disposing of used oil
and filters in an environmentally-
friendly way that complies with
the law.

The cooling system is pres-
surised. If necessary, re-
place the cap with a genuine spare
part to avoid compromising the sys-
tem efficiency.
WARNING
Do not remove the reservoir
cap when the engine is hot:
you risk scalding yourself.
WARNING
Top up only with the
same fluid contained in
the cooling circuit.
PARAFLU UP (red) cannot be
mixed with PARAFLU 11 (blue)
or with other fluids. Should this
take place, donot start the engine
and contact Fiat Dealership.

171VEHICLE MAINTENANCE
WINDSCREEN WASHER
FLUID
To add fluid, remove cap A-fig. 10
from the reservoir and slowly pour in
a mixture of water and TUTELA
PROFESSIONAL SC35fluid in the
following concentrations:
– 30% ofTUTELA PROFES-
SIONAL SC35and 70% of water in
summer.
– 50% ofTUTELA PROFES-
SIONAL SC35and 50% of water in
winter.
If the temperature falls below –20°C,
useTUTELA PROFESSIONAL
SC35undiluted.
POWER STEERING
FLUID
Check the oil level when the engine
is cold. It should be slightly under the
reference line on the reservoir.
When the oil is hot, the level can ex-
ceed the reference line.
When topping up, remove the reser-
voir cap A-fig. 11 and make sure that
the oil has the same specifications as
the oil in the system.Oil consumption is ex-
tremely low. If the oil
level needs topping up
again after a short period of
time, have the system checked
for leakage at a Fiat Dealership.

Do not let the power steer-
ing fluid come into contact
with hot engine parts. It catches fire
very easily.
WARNINGSome windscreen washer
additives on the market are
flammable. The engine compart-
ment contains hot parts which
could ignite the fluid in the event of
contact.
WARNING
Do not travel with the wind-
screen washer reservoir
empty. The windscreen washer is
fundamental for improving visibility.
WARNING

175VEHICLE MAINTENANCE
When working on the bat-
tery or near it, always wear
the proper goggles.
WARNING
Running the battery with
low fluid level can damage
the battery beyond repair and
could also cause its explosion.
WARNING
If the vehicle is to stand for
a long time in the cold, re-
move the battery and store it in a
warm place to avoid it freezing.
WARNINGCHECKING THE CHARGE
The battery charge may be checked
satisfactorily through the indicator and
acting according to the colour the in-
dicator shows.
Refer to the table below or to the la-
belB-fig. 15on the battery.USEFUL ADVICE FOR
LENGTHENING THE LIFE OF
YOUR BATTERY
When you park the vehicle, ensure
the doors are closed properly. The
ceiling lights must be off.
Do not keep accessories (e.g.: sound
system, hazard lights, etc.) switched
on for a long time when the engine is
not running.
IMPORTANTA battery which is
kept at a charge of less than 50% for
any length of time will be damaged by
sulphation leading to a reduction in
cranking power and a higher risk of the
battery electrolyte freezing (this may
even occur at –10 °C).

Furthermore, remember that high in-
take electric devices (such as baby bot-
tle warmers, vacuum cleaners, cellular
phones, mini-fridges, etc.) powered
when the engine is offcan deploy
the battery.
IMPORTANTWhen installing ad-
ditional systems on the vehicle, bear
in mind that improper branches on
connections of the vehicle wiring are
dangerous, particularly if safety devices
are involved.
Battery
60 Ah
88 Ah

The total intake of these systems
(factory and after-market) must be
less than 0.6 mA x Ah (of the bat-
tery) as shown in the following table:
Maximum

intake
36 mA
52.8 mA
60 mA
If the vehicle is inactive for a long pe-
riod of time, refer to the “Vehicle stor-
age” paragraph in section “Getting the
best out of you vehicle”.
Before performing any operation on
the electrical system, disconnect the
battery negative cable.
Battery terminals shall always be
perfectly separated.
If you want to add accessories after
buying the vehicle (antitheft system,
free-hand phone kit, radio navigator,
etc.) visit a Fiat Dealership. They
can suggest the most suitable acces-
sories to get and check whether the
electric system can support the
required load or whether a higher
capacity battery is required.
These devices will, in fact, run off
the battery even when the key is not
inserted (vehicle parked, engine off).

177VEHICLE MAINTENANCE
ELECTRONIC
CONTROL UNIT
When the vehicle is being used nor-
mally, special measures are not nec-
essary.
The following instructions must be
followed very carefully however, if
you work on the electrical system or
in cases where emergency starting is
necessary:
– never disconnect the battery from
the electric system while the engine is
running;
– disconnect the battery from the
electric system if you are recharging it;
– never perform emergency starting
with a battery charger. Always use an
auxiliary battery;
– be particularly careful when con-
necting the battery to the electric sys-
tem. Make sure that the polarity is
correct and that the connection is ef-
ficient;
– do not connect or disconnect the
terminals of the electronic units while
the ignition key is at MAR;
– do not check polarity through
sparking;– disconnect the electronic control
units if you are electrically welding the
vehicle body. Remove the units if tem-
peratures exceed 80 °C (special op-
erations on the bodywork, etc.).
IMPORTANTIf the sound system
or vehicle alarm systems are not in-
stalled correctly, they can interfere
with the working of the electronic
control units.
Modifications or repairs to
the electrical system car-
ried out incorrectly and without
bearing the features of the system
in mind can cause malfunctions
with the risk of fire.
WARNING
SPEED LIMITER
On certain version, the injection con-
trol unit is set to limit the vehicle
speed at a max. preset limit.
Speed limits are the following:
– for Minibus versions (M2 homolo-
gation category): 100 km/h;
– for good Transport versions (ve-
hicle dead weight: > 3.5 t) (N2 ho-
mologation category): 90 km/h;
Label (fig.16) with admitted top
speed (90 or 100 km/h according to
versions) is applied on the wind-
screen.
This limit has been established by Eu-
ropean Directive 2002/85/EC, what-
ever violation is therefore punishable
by law.
IMPORTANTWhen the device
comes into action, the speed value
displayed on the instrument panel
could be approx. 10% higher than the
actual one.

The cleanness and soundness of the
spark plugs are very important for
keeping the engine efficient and pol-
luting emissions down.
The appearance of the spark plug, if
examined by an expert eyes, is a good
way of pinpointing a problem even if it
has nothing to do with the ignition sys-
tem. Therefore, if the engine has prob-
lems, it is important to have the spark
plugs checked at a Fiat Dealership.
The spark plugs must be
changed at the times
specified in the
SERVICE
SCHEDULE
. Only use the type of
plugs indicated: if the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.
Modifications or repairs to
the fuel feed system that
are not carried out properly or do
not take the system’s technical
specifications into account can
cause malfunctions leading to the
risk of fire.
