PETROL ENGINES

DIESEL ENGINES

AT THE FILLING

STATION

Use only unleaded petrol.

To prevent errors, the diameter of

the fuel tank filler is too small to in-

troduce a lead petrol pump filler.

Use diesel fuel for motor

vehicles complying with

European specifications

Use petrol with a rated octane num-

ber (R.O.N.) not lower than 95.

EN590 only. The use of other

products or mixtures may dam-

age the engine beyond repair and

invalidate the warranty. If the

tank is accidentally filled with oth-

er types of fuel, do not start the

engine and drain the tank. If the

engine has run even for a very

short time, you will also need to

drain the fuel supply circuit.

Make sure that the left-

hand sliding side door is

completely closed before

IMPORTANT An inefficient cat-

alytic converter will allow harmful ex-

haust fumes to be emitted and thus

contribute to air pollution.

refuelling. You could damage the

door and the sliding lock system

which comes into play when the

fuel flap is open.

IMPORTANT Never put even the

tiniest amount of leaded petrol in the

fuel tank of your vehicle even in an

emergency. You would damage the

catalytic converter beyond repair.

You cannot open the

left-hand sliding side door

while refuelling when the

flap is open.

If the outside temperature is very

low, the diesel thickens due to the for-

mation of paraffin and could clog the

fuel filter.

FUEL FILLER CAP fig. 150

To open:

1) Turn the cap by approximately half

a turn anticlockwise and remove it.

Make sure that the left-

hand sliding side door is

completely closed before

In order to avoid these problems, dif-

ferent types of diesel are distributed

according to the season: summer type,

winter type and arctic type (cold

mountain areas).

IMPORTANT The hermetic clo-

sure may cause a slight pressure in the

tank: a slight hissing when turning the

cap is quite normal.

refuelling. You could damage the

door and the sliding lock system

which comes into play when the

fuel flap is open.

2) While you are filling up, place the

cap on the fuel filler flap as illustrated

in the figure.

If refuelling with diesel fuel not ade-

quate, you are recommended to add

TUTELA DIESEL ART to the fuel,

in the proportions written on the con-

tainer. Pour the antifreeze into the fu-

el tank before the fuel.

To close:

The cap has a bayonet coupling. In-

sert the cap and turn it clockwise un-

til it clicks once or more.

You cannot open the

left-hand sliding side door

while refuelling when the

flap is open.

REFUELLING

To guarantee full tank filling, carry

out two refuelling operations after the

first click of the fuel delivery gun.

Avoid further topping up operations

that could cause damages to the fuel

system.

On certain versions the cap has a

mechanical lock to be opened using

the door key.

The devices for curtailing diesel en-

gine emissions are:

PROTECTING THE

ENVIRONMENT

– an oxidising catalytic converter;

Protecting the environment has been

the guiding principle in the design of

the Fiat Doblò right from the start.

The result is the use of materials and

creation of devices that can reduce or

considerably curtail harmful influences

on the environment.

– an exhaust gas recirculation system

(E.G.R.).

– diesel particulate filter (DPF)

– Lambda probes (where provided).

Consequently, the Fiat Doblò is ready

to travel well ahead of the most strin-

gent international pollution control

standards.

Do not put naked flames

or lighted cigarettes near

the fuel filler hole as there

is a danger of fire. Do not bend

too close to the hole either so as

not to breathe in harmful

vapours.

The devices for curtailing petrol en-

gine emissions are the following:

– a three-way catalytic converter;

– Lambda sensors (oxygen sensors);

– a fuel evaporation system.

IMPORTANT If required, replace

the fuel cap with another genuine cap

to avoid affecting the efficiency of the

fuel vapour recovery system.

DIESEL PARTICULATE

FILTER (DPF) (for Multijet

versions 1.3 85 HP and 1.9 120

HP)

Since this filter physically traps partic-

ulates, it shall be cleaned (reclaimed) at

regular intervals by burning carbon par-

ticles.

Reclaiming procedure is controlled

automatically by the engine control unit

according to the filter conditions and

the conditions of use of the vehicle.

The Diesel Particulate Filter is a me-

chanical filter, integral with the exhaust

system, that physically traps particulates

present in the exhaust gases of Diesel

engines.

During reclaiming the following phe-

nomena could take place: idling slight

increase, fan activation, slight smoke in-

crease, high exhaust temperatures.

These situations shall not be considered

as faults and they do not affect vehicle

performance and environment.

The diesel particular filter has been

adopted to eliminate almost totally par-

ticulates in compliance with current /

future law regulations.

During normal use of the vehicle, the

engine control unit records a set of da-

ta (e.g.: travel time, type of route, tem-

peratures, etc.) and it will then calcu-

late how much particulates has been

trapped by the filter.

If the dedicated message is displayed,

refer to paragraph “Warning lights and

messages”.
