2007 FIAT DOBLO lambda sensor

104GETTING TO KNOW YOUR VEHICLE
On certain versions the cap has a
mechanical lock to be opened using
the door key. PROTECTING THE
ENVIRONMENT
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.
The devices for curtailing petrol en-
gine emissions are the following:
– a three-way catalytic converter;
– Lambda sensors (oxygen sensors);
– a fuel evaporation system. 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.
IMPORTANTIf required, replace
the fuel cap with another genuine cap
to avoid affecting the efficiency of the
fuel vapour recovery system.
The devices for curtailing diesel en-
gine emissions are:
– an oxidising catalytic converter;
– 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.

TOWING TRAILERS
IMPORTANT NOTES
The vehicle must be fitted with a ho-
mologated tow hitch and suitable elec-
trical system for towing a caravan or
trailer. Installation must be carried out
by skilled personnel who will issue
documentation authorising circulation
on the road.
Install any specific and/or additional
rear-view mirrors in accordance with
the Highway Code.
Remember that towing a trailer
makes it harder for the vehicle to
climb the maximum gradients speci-
fied.Engage a low gear when driving
downhill rather than constantly brak-
ing.
The weight the trailer exerts on the
vehicle’s tow hitch coupling reduces
the vehicle’s payload by the same
amount.
To make sure the maximum towable
weight is not exceeded (given in the
log book) account should be taken of
the fully laden trailer, including acces-
sories and personal belongings.
Respect the speed limit for towing
trailers in the country you are travel-
ling in. In any case, do not exceed a
maximum speed of 100 km/h. Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe.
When functioning nor-
mally the catalytic con-
verter reaches high tem-
peratures. For this reason do not
park the vehicle over inflamma-
ble material (grass, dry leaves,
pine needles etc.): fire hazard.
Ignoring the above rules
may lead to fire.
