EOBD SYSTEM
The European On Board Diagnostic system (EOBD) fitted to engine and
automatic transmission (where provided) electronic control units allows
monitoring and warning of any malfunction to the electronic systems that
could increase exhaust emissions.
The objective is:
❒To keep system efficiency under control
❒Warn when a fault causes emission levels to increase
❒Warn of the need to replace deteriorated components
This diagnostic system indicates the presence of deteriorated
components or system malfunctioning (see section “Warning lights and
Messages”) by the turning on of the instrument panel warning light
U
(together with the relevant message on the multifunction display, where
provided).
NOTE: The car is provided with a diagnostic connector that can be
interfaced with appropriate tools, which makes it possible to read the
error codes stored in the control units, together with a series of specific
parameters for engine operation and diagnosis.
This test can also be performed by traffic controller agents.
IMPORTANT: After a servicing operation at Fiat Dealership aimed to
eliminate malfunctioning connected to the EOBD system, in order to
check the system thoroughly it could be required to run a bench test
and, if necessary, road tests which may also call for a long journey.
F0G0382m
If turning the ignition key to MAR, the warning light Udoes not turn on or if, while travelling it
turns on glowing steadily or flashing (together with the message on the multifunction display),
contact Fiat Dealership as soon as possible. Warning light
Uoperation can be checked by means
of special equipment by traffic controller agents. Always comply with the traffic regulations in force
in the country where you are travelling.

PROTECTING
THE ENVIRONMENT
Protecting the environment has been the guiding
principle in the design of the Fiat Multipla right from
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 engine emissions are
the following:
❒three-way catalytic converter;
❒Lambda sensor;
❒fuel evaporation system.
The devices for curtailing diesel fuel engine emissions
are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system (E.G.R.).
As a consequence Fiat Multipla is ready to travel with
several advantage points over the most severe
international anti-pollution regulations.
During normal service the catalytic converter reaches high temperatures.
Therefore, do not park the car over inflammable material (grass, dry leaves, pine
needles, etc.): fire danger.WARNING

DIESEL PARTICULATE FILTER (DPF)
The Diesel Particulate Filter is a mechanical filter,
integral with the exhaust system, that physically traps
particulates present in the exhaust gases of Diesel
engines.
The diesel particular filter has been adopted to
eliminate almost totally particulates in compliance with
current / future law regulations.
During normal use of the car, the engine control unit
records a set of data (e.g.: travel time, type of route,
temperatures, etc.) and it will then calculate how much
particulates has been trapped by the filter.
Since this filter physically traps particulates, it shall be
cleaned (reclaimed) at regular intervals by burning
carbon particles.
Reclaiming procedure is controlled automatically by
the engine control unit according to the filter
conditions and the conditions of use of the car.During reclaiming the following phenomena could take
place: idling slight increase, fan activation, slight smoke
increase, high exhaust temperatures. These situations
shall not be considered as faults and they do not affect
car performance and environment.
If the dedicated message is displayed, refer to section
“Warning lights and messages”.

CORRECT USE
OF THE CAR
If the engine does not start at the first attempt, return
the ignition key to STOP before trying to start the
engine again.
If, when the ignition key is at MAR, warning light
¢
remains lit, turn the key to STOP and then back to
MAR; if the warning light remains on, try with the
other keys provided with the car.
If you still cannot start the engine, contact Fiat
Dealership.
IMPORTANT When the outside temperature is very
low, the use of a fluid oil facilitates cold starting.
During winter it is therefore recommended to
observe the specifications contained in section
“Technical specifications” at paragraph “Fluids and
lubricants”.
IMPORTANT Never leave the ignition key at MAR
when the engine is off.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
(petrol and diesel versions)
Proceed as follows:
❒drive off slowly, letting the engine turn at medium
revs. Do not accelerate abruptly.
❒do not drive at full performance for the initial
kilometres.
EMERGENCY START-UP
If the Fiat CODE system fails to recognise the code
transmitted by the ignition key (warning light
¢on
instrument panel lit with fixed light) you can start the
engine by following the emergency procedure using
the code written on the CODE card.
See section “In an emergency”.
Never bump start the engine by pushing, towing or coasting downhill as this could cause fuel to
flow into the catalytic exhaust system and damage it beyond repair.
Remember that the servobrake and power steering are not operational until the
engine has been started, therefore much effort than usual is required on the brake
pedal and steering wheel.WARNING

Warning Messagelight on panel on display
EOBD / INJECTION SYSTEM FAILURE (amber)
In normal conditions, turning the ignition key to MAR, the warning light turns on, but it should go
off when the engine has started.
The warning light stays on or turns on when travelling to indicate injection system malfunctioning;
in particular the warning light turns on glowing steadily to indicate a fault in the supply/ignition
system which could cause high emissions at the exhaust, possible lack of performance, poor han-
dling and high consumption levels.
On certain versions the dedicated message is displayed.
In these conditions it is possible to continue driving without however requiring heavy effort or high
speed from the engine. Prolonged use of the car with the warning light on may cause damages. Con-
tact Fiat Dealership as soon as possible.
The warning light goes off if the fault disappears, the system will in any case store the fault.
NOTE (valid for petrol versions only)
The warning light turns on flashing to indicate a possible damage to the catalyst.
If the warning light flashes, it is necessary to release the accelerator pedal to lower the speed of
the engine until the warning light stops flashing; continue the journey at moderate speed, trying to
avoid driving conditions that may cause further flashing and contact Fiat Dealership as soon as
possible.
If, turning the ignition key to MAR, the warning lightUdoes not turn on or if it turns on glowing
steadily or flashing when travelling (on certain versions together with the dedicated message on the
display), contact Fiat Dealership as soon as possible. Warning light
Uoperation can be checked by
traffic agents by proper equipment therefore, comply with laws and regulations in force in the
country where you are driving.
