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.

183VEHICLE MAINTENANCE
Do not wash the vehicle after it has
been parked in the sun or while the
bonnet is hot: it could take the shine
off the paint.
Outside plastic parts must be
cleaned following the usual vehicle
washing procedure.
Where possible avoid parking the
vehicle under trees; the resinous sub-
stances that certain species of tree
shed dull the paintwork and increase
the possibility of rust forming.To better protect the paintwork,
polish with protective wax from time
to time, that leaves a protective layer
on the paintwork.
When the paintwork tends to lose
its shine because of the build-up of
smog, use a wax (polish) which has a
slightly abrasive as well as protective
action.
Front headlights
IMPORTANTNever use aromat-
ic substances (e.g.: petrol) or ketones
(e.g.: acetone) for cleaning front head-
light plastic lens.
Windows
Use specific window cleaners to
clean the windows. Use very clean
cloths to avoid scratching the glass or
damaging its transparency.
IMPORTANTTo prevent damage
to the electric heater element, wipe
the inside of the heated rear window
(where fitted) gently in the same di-
rection as the elements.Engine compartment
At the end of each winter season,
carefully clean the engine compart-
ment. Have this done at a garage.
IMPORTANTThe engine com-
partment should be washed while the
engine is cold and with the ignition key
at STOP. After washing, make sure
that the various protections (e.g. rub-
ber boots and various guards) have
not be removed or damaged.
Detergents pollute wa-
ter. For this reason, the
vehicle must be washed
in an area equipped for the col-
lection and purification of the liq-
uids used while washing.
IMPORTANTBird droppings
must be washed off immediately and
with great care as their acid is partic-
ularly aggressive.
Detergents pollute wa-
ter. The vehicle must
therefore be washed in an
area equipped for the collection
and purification of the liquids
used while washing.
