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.

SPARK PLUGS
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.
