VEHICLE MAINTENANCE for Your Fiat Doblo Van 2000-2009

– In pile-ups on the motorway, par-  
ticularly when the visibility is bad,  
there is a high risk of other vehicles  
running into those already stopped.  
Get out of the vehicle immediately and  
take refuge behind the guard rail.  
IF ANYONE IS INJURED  
FIRST-AID KIT  
– Never leave the injured person  
alone. The obligation to provide as-  
sistance exists even for those not di-  
rectly involved in the accident.  
It is a good idea to keep a fire extin-  
guisher and blanket in the vehicle in  
addition to the first-aid kit.  
The first aid kit can be arranged on  
the shelf as shown in fig. 48.  
– Do not congregate around the in-  
jured person.  
– If the doors are blocked, do not at-  
tempt to smash the windscreen to get  
out of the vehicle. It is made of layered  
glass and is very hard. Side and rear  
windows are much more easily bro-  
ken.  
– Reassure the injured person that  
help is on its way and will arrive soon.  
Stay close by to calm him/her down in  
case of panic.  
– Remove the ignition keys from the  
vehicles involved.  
– Unfasten or cut seat belts holding  
injured parties.  
– If you can smell petrol or other  
chemicals, do not smoke and make  
sure all cigarettes are extinguished.  
– Do not give an injured person any-  
thing to drink.  
– Do not move an injured person un-  
less the following situations arise.  
– Use a fire extinguisher, blanket,  
sand or earth to put out fires no mat-  
ter how small they are. Never use wa-  
ter.  
– Pull the injured person from the ve-  
hicle only if it risks catching fire, it is  
sinking in water or is likely to fall over  
a cliff or similar. Do not pull his/her  
arms or legs, do not bend the head  
and, as far as possible, keep the body  
horizontal.

VEHICLE MAINTENANCE  
IMPORTANT The Manufacturer  
requires the Service Schedule coupon-  
related checks to be carried out. Fail-  
ure to do so could result in the war-  
ranty being cancelled for those defects  
that can be attributed to such failure.  
IMPORTANT You are recom-

SERVICING  
mended to get in touch with a Fiat  
Dealership immediately if any minor  
running problems crop up without  
waiting for the next coupon.  
Correct maintenance of the vehicle  
is essential for ensuring it stays in tip-  
top condition for a long time to come.  
Scheduled Servicing is performed at  
all Fiat Dealerships and there is a set  
time scale for such operations.  
This is why Fiat has programmed a  
series of checks and maintenance op-  
erations every 20,000 km.  
If during each operation, in addition  
to the ones programmed, the need  
arises for further replacements or re-  
pairs, these may be carried out only  
with the explicit agreement of the  
Customer.  
It is however important to remem-  
ber that scheduled servicing is not all  
your vehicle requires. Regular checked  
- also in the initial period before the  
20,000 kilometre coupon and later be-  
tween coupons - ordinary care is re-  
quired, such as checking fluid levels  
and topping up, checking tyre inflation  
pressure, etc...

IMPORTANT - Engine oil  
IMPORTANT - Pollen filter  
You should check the battery fluid  
(electrolyte) level more frequently  
than shown in the service schedule in  
this chapter if the vehicle is used in hot  
climates or particularly demanding  
conditions.  
Should prevailing use of the vehicle  
be under one of the following special-  
ly heavy conditions:  
– towing a trailer  
– on dirty roads  
– for short, repeated trips (less than  
7-8 km) with outside temperature be-  
low zero  
If the vehicle is used frequently in  
dusty or heavily polluted environ-  
ments it is advisable to replace the fil-  
tering element more frequently; in  
particular it should be replaced if a re-  
duction of the amount of air admitted  
to the passenger compartment is not-  
ed.  
– frequently idling engines or long  
distance low speed driving (e.g. taxis  
or door-to-door deliveries) or in case  
of a long term inactivity; replace en-  
gine oil more frequently than required  
on Service schedule  
IMPORTANT - Battery  
Maintenance of your ve-  
hicle should be entrusted  
The charge in your battery should be  
checked, where possible at the start  
of the winter, to limit the risk of the  
battery electrolyte freezing. This check  
should be carried out more frequent-  
ly if the vehicle is mainly used for short  
trips or if it is fitted with accessories  
that permanently take in electricity  
even when the ignition key is re-  
moved, especially in the case of after  
market accessories.

ordinary routine maintenance  
operations which you are able to  
carry out yourself, ensure that  
you have the necessary tools and  
original Fiat spare parts and flu-  
ids available. Do not carry out  
servicing operations if you have  
no experience.  
IMPORTANT - Air cleaner  
If the vehicle is used on dusty roads  
change the air cleaner more frequently  
than the indications in the Service  
schedule. If in doubt as to how often  
the engine oil and air cleaner should  
be changed according to how you use  
the vehicle, contact a Fiat Dealer-

the filler until it reaches the MAX  
mark.  
Check engine oil with the vehicle on  
level ground and while the engine is  
still warm (approximately 5 minutes  
after stopping the engine.  
Oil level shall never exceed the  
MAX mark.  
The oil level should be included be-  
tween the MIN and MAX reference

During the beginning of the vehicle’s  
life the engine is be tuned in. Engine oil  
consumption can only be considered  
stabilised after the first 5000 ÷ 6000  
km.  
IMPORTANT After topping up or  
changing the oil, let the engine turn for  
a few seconds and wait a few minutes  
after stopping it before you check the  
level.

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.  
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

USEFUL ADVICE FOR  
LENGTHENING THE LIFE OF  
YOUR BATTERY  
To avoid draining your battery and  
lengthen its life, observe the follow-  
ing indications:  
These devices will, in fact, run off the  
battery even when the key is not in-  
serted (vehicle parked) and can deploy  
the battery.  
– when you park the vehicle, ensure

The following instructions must be  
followed very carefully, however, if  
you work on the electrical system or  
in cases where emergency starting is  
necessary:  
– Disconnect the electronic units if  
you are electrically welding the vehi-  
cle body. Remove the units if temper-  
atures exceed 80°C (special opera-  
tions on the bodywork, etc.).  
– Never disconnect the battery from  
the electrical system while the engine

rectly, they can interfere with the  
working of the electronic control  
units.

TYRE PRESSURE  
Check the pressure of each tyre, in-

can damage the tyres.  
See “Wheels” in “Technical specifi-  
cations” for the correct tyre inflation

Avoid overloading your vehicle: this  
can seriously damage wheels and tyres.  
If you replace a tyre it is a good idea  
to change the inflation valve, too.  
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.  
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.  
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.  
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.  
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.  
The Fiat Doblò fits tubeless tyres.  
Under no circumstances use an inner  
tube with these tyres.

you will avoid straining the electric

it to overheat.

1) Lift the windscreen wiper arm A-  
fig. 23 off the glass and position the  
blade so as to form a right angle with  
the arm.  
– Do not operate the windscreen or  
rear window wipers on dry glass.  
BLADES  
2) Press tab B on the retainer and  
remove the blade to be replaced from  
arm A .  
Periodically clean the rubber part us-  
ing special products; TUTELA PRO-  
FESSIONAL SC 35 is recommend-  
ed.  
3) Fit the new blade by inserting the  
tab into the special slot in the arm.  
Make sure it is properly locked into  
place.  
Driving with worn wiper  
blades is a serious hazard,  
because visibility is re-  
duced in bad weather.  
If the rubber blades are bent or worn  
they should be replaced. In any case  
they should be changed once a year.  
A few simple notions can reduce the  
possibility of damage to the blades:  
– If the temperature falls to below  
zero, make sure the rubber blade is  
not frozen to the windscreen. If nec-  
essary, free it with a de-icing com-  
pound.

SPRAY NOZZLES  
The rear window washer jet fig. 27  
can be directed by adjusting the di-  
rection of the nozzles.  
If there is no jet of liquid, first make  
sure that there is liquid in the reser-  
voir: see “Checking fluid levels” in this  
section.  
1) Lift the cover A-fig. 24 and fig.  
25 and dismantle the arm from the ve-  
hicle by unscrewing the nut B which  
holds it onto the knuckle.  
Then make sure that the holes in the  
nozzles are not clogged up. Use a pin  
for this if necessary.  
2) Position the new arm correctly  
and fasten the nut.  
The windscreen washer jets fig. 26  
can be directed by adjusting the incli-  
nation of the nozzles. Direct the spray  
so that it reaches the highest point  
reached by the blades.  
3) Lower the cover.

ADVICE FOR PRESERVING  
THE BODYWORK  
BODYWORK  
PROTECTION FROM  
ATMOSPHERIC AGENTS  
Paint  
Paintwork does not only serve an  
aesthetic purpose, but also protects  
the underlying sheet metal.  
The main causes of rust are:  
– atmospheric pollution  
– Spraying plastic-coating materials  
to protect the most exposed points:  
under the door, inside the wings, the  
edges etc.  
In the case of deep scrapes or scores,  
you are advised to have the necessary  
touching up carried out immediately  
to avoid the formation of rust.  
– salt and humidity in the atmosphere  
(coastal or very hot and humid areas)  
– The use of “open” box sections to  
prevent condensation and water from  
building up and rusting the inside of  
the parts.  
– environmental conditions that are  
specific to the season.  
Only use genuine products when  
touching up the paintwork (see “Body-  
work paint identification plate” in sec-  
tion “Technical specifications”).  
Not to be underestimated is also the  
abrasive action of wind-borne atmos-  
pheric dust and sand and mud and  
gravel raised by other vehicles.  
BODY AND UNDERBODY  
WARRANTY  
Ordinary maintenance of the paint-  
work means washing it. The frequen-  
cy you should do this depends on the  
conditions and the environment the  
vehicle is driven in. For example, in ar-  
eas with a high level of air pollution or  
on roads sprinkled with road salt,  
wash the vehicle more frequently.  
Your Fiat Doblò is covered by war-  
ranty against any original structural or  
body part being perforated by rust.  
Refer to the Warranty Booklet for the  
general terms.  
For your Fiat Doblò, Fiat has used  
leading-edge technological solutions to  
effectively protect the body from rust.  
These include:  
– Painting systems and products that  
make the vehicle particularly resistant  
to rust and scratching.  
– The use of zinc-plated sheet steel  
which is highly resistant to rust.

Outside plastic parts must be cleaned  
following the usual vehicle washing  
procedure.  
To wash the vehicle properly:  
Where possible avoid parking the ve-  
hicle under trees; the resinous sub-  
stances that certain species of tree  
shed dull the paintwork and increase  
the possibility of rust forming.

used while washing.  
3) Wipe a sponge with a slightly  
soapy solution over the bodywork,  
frequently rinsing the sponge.  
4) Rinse well with water and dry  
with a jet of air or a chamois leather.  
Windows  
Use specific window cleaner prod-  
ucts to clean cloths to avoid scratch-  
ing the glass or damaging the trans-  
parency.  
When drying the vehicle, be careful  
to get at those parts which are not so  
easily seen e.g. the door frames, bon-  
net and around the headlights where  
water can most readily collect. You  
should leave the vehicle out in the  
open so that any water remaining can  
evaporate more easily.  
IMPORTANT The 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.  
IMPORTANT To prevent damage  
to the electric heater element, wipe the  
inside of the heated rear window gen-  
tly in the same direction as the ele-  
ments.
