DIESEL PARTICULATE
FILTER (DPF)
(2.4 JTD
20VCAE version)
The Diesel Particulate Filter is a me-
chanical filter, integral with the ex-
haust system, that physically traps
particulate present in the exhaust
gases of Diesel engines.
The diesel particular filter has been
adopted to eliminate almost totally
particulates in compliance with cur-
rent / 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 par-
ticulates, it shall be cleaned (re-
claimed) at regular intervals by burn-
ing carbon particles. Reclaiming pro-
cedure is controlled automatically by
the engine control unit according to
the filter conditions and the condi-
tions of use of the car. During re-
claiming the following phenomena
could take place: idling slight in-
crease, fan activation, slight smoke in-
crease, high exhaust temperatures.
These situations shall not be consid-
ered as faults and they do not affect
car performance and environment. Diesel particulate filter clogged
When the Diesel particulate filter is
clogged, the instrument panel warn-
ing light èwill turn on (on certain
versions symbol èis displayed). In
this case keep the car running until
warning light è(or symbol è) turns
off.

HEADLIGHTS
GAS-DISCHARGE (BI-XENO)
MAIN BEAM / DIPPED BEAM
HEADLIGHTS AND DYNAMIC
BEAM ADJUSTMENT DEVICE
These headlights, called Bi-Xeno,
use a lamp with a xenon-filled bulb,
both for the dipped beam and the
main beam headlights.
The main characteristics of this
type of headlights are:
– higher brilliancy
– higher light beam width and
adjustability
– lower consumption under work-
ing conditions
– longer bulb life.Each headlight is equipped with an
electronic control unit used to con-
trol supply voltage. Due to high bril-
liancy, bi-Xeno headlights require
the adoption of a dynamic beam
adjustment control system.
This system is controlled by an
electronic control unit operating at
two levels:
– constant headlight beam realign-
ment as a function of the car load
– dynamic headlight beam align-
ment to compensate car pitching
when running.Operation
Light is projected onto the road by
means of a spherical glass lens with
a large surface (70 mm diameter).
A deflector lifts and lowers, so that
light distribution is different for
both the main beam and dipped
beam headlights. The deflector is
electrically operated and the
mechanical lifting/lowering opera-
tion is performed real-time when
lights are switched.
The xenon lamp consists of a bulb
containing low-pressure xenon and
two electrodes.
To obtain light emission, an elec-
tric arc must be triggered between
the two electrodes and maintained.
Each headlight is equipped with a
control unit which:
– checks the voltage/current value
under working operation
– triggers the arc to the electrodes
and cause salt evaporation at
switching on.

Do not smoke while
working in the engine
compartment: the pres-
ence of flammable gas and
vapour could cause a fire.
Be careful not to mix up
the various types of fluids
when you are topping up:
they are all mutually incompati-
ble and could damage the car.
Maintenance of your car
should be entrusted to a
Lancia Dealership. For
ordinary routine maintenance
operations which you are able to
carry out yourself, ensure that
you have the necessary tools and
original Lancia spare parts and
fluids available. Do not carry out
servicing operations if you have
no experience.IMPORTANT - Engine oil
If the car is normally driven in one
of the following particularly severe
conditions:
– towing a trailer
– on dirty roads
– for short, repeated trips (less
than 7-8 km) with outside tempera-
ture below zero
– with engine frequently idling or
for long distances at low speed (e.g.
taxi, door-to-door deliveries) or pro-
longed storage
change the engine oil more frequent-
ly than shown in the Service
Schedule.
IMPORTANT - Air cleaner
Replace the air cleaner more fre-
quently than shown in the Service
Schedule if the car is used on dusty
roads.
If you are in doubt about how often
the engine oil or the air cleaner
should be changed in relation to how
you use the car, contact a Lancia
Dealership.
