161VEHICLE MAINTENANCE
IMPORTANTBrake fluid is hy-
groscopic (meaning it absorbs humid-
ity). This is why the fluid should be
changed more frequently than shown
in the service schedule if the vehicle is
mainly driven in areas with a high per-
centage of humidity in the air.
fig. 15
F0A0127b
Brake fluid is poisonous
and very corrosive. In the
event of accidental con-
tact, wash the effected part with
water and mild soap and rinse. If
the fluid is swallowed, call a doc-
tor immediately.The symbol πon the
container indicates syn-
thetic brake fluid distin-
guishing it from mineral fluid. Us-
ing mineral type fluid would dam-
age the special rubber braking
system gaskets beyond repair.POLLEN FILTER
The pollen filter is located under the
dashboard near the central dashboard
unit on passenger side.
If the vehicle is often used in dusty or
extremely polluted environments, you
should change the filter element more
frequently than shown in the service
schedule. It should be changed espe-
cially if the amount of air introduced
into the passenger compartment is in-
troduced.

164VEHICLE MAINTENANCE
Incorrect fitting of elec-
trical and electronic ac-
cessories can seriously
damage the vehicle.
If after buying the vehicle, you
want to install electric acces-
sories which require permanent
electric supply (alarm, free-hand
phone kit, etc.) contact Fiat Deal-
ership whose qualified personnel,
in addition to suggesting the
most suitable devices, will evalu-
ate the overall electric absorp-
tion, checking whether the vehi-
cle electric system is capable of
withstanding the load required,
or whether it should be integrat-
ed with a more powerful battery.
Batteries contain sub-
stances that are very
harmful for the environ-
ment. You are advised to have
the battery changed at a Fiat
Dealership. It is properly
equipped for disposing of used
batteries in an environmentally-
friendly way that complies with
the law.The liquid in the battery
is poisonous and corro-
sive. Avoid contact with
eyes and skin. Do not bring naked
flames or possible sources of
sparks near the battery: risk of
fire and explosion.CHANGING THE BATTERY
If required, replace the battery with
a genuine spare part having the same
specifications.
If a battery with different specifica-
tions is fitted, the service intervals giv-
en in the “Service schedule” in this
section will no longer be valid. Refer
therefore to the instructions provid-
ed by the battery manufacturer.
Running the battery
with low fluid level can
damage the battery be-
yond repair and could also cause
its explosion.

168VEHICLE MAINTENANCE
Avoid overloading your vehicle: this
can seriously damage wheels and tyres.
If you get a flat tyre, stop immediately
and change it so as not to damage the
tyre, the wheel, the suspension and
the steering.
Tyres age even if they are not used
very much. Cracking of the tread rub-
ber and the side walls are a sign of this
ageing. In any case, if the tyres have
been fitted for more than six years
they should be examined by an expert
who can judge whether they are still
fit for use. Remember to check the
spare tyre particularly carefully too.
If a replacement is necessary, always
use new tyres and avoid using ones the
origin of which you are not certain
about.
The Fiat Doblò fits tubeless tyres.
Under no circumstances use an inner
tube with these tyres.If you replace a tyre it is a good idea
to change the inflation valve, too.
To ensure the front and rear tyres all
wear evenly, you are advised to change
the tyres over every 10-15 thousand
kilometres keeping them on the same
side of the vehicle so as not to reverse
the direction of rotation.
Do not change the tyres
over in criss-cross fashion
by moving a tyre from the
left hand side of the vehicle to the
right and vice versa.RUBBER TUBING
Follow the “Service Schedule” to the
letter as concerns braking and fuel line
rubber tubing. Ozone, high tempera-
tures and long absence of fluid in the
system can in fact cause the hardening
and cracking of the pipes with possi-
ble loss of fluid. A careful check is
therefore essential.
