The dust/pollen filter should be checked
over at least once a year by Alfa Romeo
Authorized Services, preferably at the be-
ginning of summer.
If the vehicle is habitually driven in pol-
luted areas or on dusty roads the system
should be checked and if necessary
changed more often.If the filter is not re-
placed the efficiency of
the climate control sys-
tem may be seriously compro-
mised.ACTIVATED CARBON
DUST/POLLEN AIR FILTER
The filter has the specific capability to
combine the mechanical air filtering func-
tion with an electrostatic effect so that
the outside air admitted to the passenger
compartment is purified and free of parti-
cles such as dust, pollen etc.
In addition to the above-mentioned
function there is also an effective reduc-
tion of the concentration of pollutants
owing to a layer of activated carbons on
the lower surface of the filter.
The filtering action takes place when air
is admitted from outside (recirculation
off) and when the air is recirculated (re-
circulation on).

The temperature near
the heater should never
exceed 120°C (e.g. dur-
ing body painting operations in
the workshop oven). Higher tem-
perature could damage the elec-
tronic control unit components.
For maintenance and repairs con-
tact only Authorized Alfa Romeo
Services and only use original
spare parts.
The burner exhaust gas
is released in the centre
floor area: therefore never park
the car with the engine running
over inflammable surfaces, fire
hazard!
WARNING
IMPORTANT When the heater is
working with the vehicle stationery and
the engine running, standing outside the
car near the rear wheel arch a low noise
caused by normal operation of the heater
can be heard.MAINTENANCE
Have the additional heater checked at
regular intervals by Authorized Alfa
Romeo Services. This will ensure safe,
cost-effective working of the heater and
also long life.

position the
xwarning light will come
on on the instrument panel.To release the hand brake:
– Slightly lift the lever (A) and press
the button (B).
– holding the button down lower the
lever: the
xwarning light on the instru-
ment panel will go out.
To prevent the car from moving acciden-
tally, keep the brake pedal pressed when
engaging the handbrake.
The wheels should be
locked after a few clicks
of the hand brake lever.
if this does not occur contact Alfa
Romeo Authorized services to
have the hand brake adjusted.

SECURING THE LOAD
The loads carried may be blocked with
straps hooked to the special rings in the
boot corners (fig. 140). The rings also
serve to secure the luggage retaining net
(available on request c/o Alfa Romeo Au-
thorized Services).
fig. 140
678PGSm
Do not load the luggage
compartment above the
permitted maximum (see “Techni-
cal specifications”). Also make sure
that the objects contained in the
boot are well secured to prevent
them from being thrown forward
causing harm to the passengers in
the event of sharp braking.
WARNING
A heavy load that has not
been secured may cause
serious harm to passengers in the
event of an accident.
WARNINGIMPORTANT Travelling at night with
a load in the boot it is necessary to adjust
the height of the low beam headlights
(see next paragraph “Headlights” in this
chapter). For correct use of the aiming
device, also make sure that the load does
not exceed the values given in the same
paragraph.

111
GAS DISCHARGE HEADLIGHTS
(optional for versions/markets where
applicable)
Gas discharge headlights (xenon) work
with a voltaic arc, in an atmosphere satu-
rated with pressurised xenon gas, instead
of the incandescent filament.
The lighting produced is remarkably
higher than that of the conventional light
in both terms of the quality of the light
(lighter) and of the amplitude and posi-
tion of the lit area.
The advantages offered by better light-
ing are noted (due to less sight fatigue
and better orientation capability of the
driver, thus of travelling safety) especially
in bad weather, fog and/or insufficient
signs, because of the higher lighting
of the side beams which are normally
shaded.
The heavy increase of lighting in the
side beams considerably increases driving
safety because it allows the driver to bet-
ter see other users at the sides of the
road (pedestrians, cyclists and motorcy-
clists).Very high voltage is needed to trigger
the voltaic arc, after which the supply can
be at low voltage.
The headlights reach their maximum in-
tensity after about 15 seconds from
switching on.
The high luminosity produced by this
type of headlight calls for the use of an
automatic system to keep the headlight
beam aiming constant and prevent daz-
zling other vehicles when braking, accel-
erating and carrying loads.
The electromechanical system for auto-
matic constant beam aiming makes the
headlight aiming device superfluous.
Xenon lights are very long-lasting and
failure is unlikely.
If necessary, have the
system checked and any
repairs done only by Authorized Al-
fa Romeo Services.
WARNING

112
AIMING LOW BEAM
HEADLAMPS FOR
LEFT/RIGHT CIRCULATION
(only for versions with gas discharge
headlamps)
On cars fitted with gas discharge head-
lamps (xenon bulbs)(optional for ver-
sions/markets where applicable) with
high lighting power, when passing from a
country with right circulation to one with
left circulation or vice versa it is necessary
to change the aiming of the low beams,
to optimise lighting of the edge of the
road and avoid glaring vehicles met.
IMPORTANT Contact Alfa Romeo Au-
thorised Services to have low beam head-
lamps correctly adjusted.
BEAM AIMING
(excluding versions with gas discharge
headlights)
The adjustment of the headlights is vital
to your safety and comfort and to that of
other road users.
The adjustment of the headlights is also
governed by precise regulations.
Contact Alfa Romeo Authorized Services
to have the headlights correctly adjusted.
When returning to the
country of origin, re-
member to change the low beam
aiming again.
WARNING
To have the position
checked and if neces-
sary adjusted, contact
Alfa Romeo Authorized Services.

EOBD SYSTEM
(optional for versions/
markets where applicable
)
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the car correlated with
emissions.
This system continuously monitors the
components of the vehicle related to e-
missions; it also indicates, when the
Uwarning light comes on on the instrument
panel, that the components in question
are in poor condition.
IMPORTANTAfter the problem has
been resolved, to completely check the
system, the Alfa Romeo Authorized Ser-
vice Station must carry out tests on a test
bench and, if necessary, road tests that
could be long.If, when the ignition key
is turned to MAR, the
Uwarning light does
not come on or if, when driving, it
lights up and emits a fixed light
or a flashing one, contact an Alfa
Romeo Authorized Service Station
as soon as possible. Warning
light
Uoperation can be checked
by means of special equipment
by traffic agents. Always comply
with the traffic regulations in
force in the country where you
are travelling.
The objective is the following:
– to keep under control the efficiency of
the system;
– to warn when a fault causes emission
levels to increase;
– to indicate the need to replace the
deteriorated components.
The system also has a diagnostic con-
nector that can be interfaced with appro-
priate tools, which makes it possible to
read the error codes stored in the control
unit, together with a series of specific pa-
rameters for engine operation and diag-
nosis. This check can also be carried out
by the traffic police.
