CAR MAINTENANCE
253
Car maintenance should be
entrusted to Alfa Romeo
Authorized Services. For
routine and minor maintenance op-
erations you wish to carry out
yourself, always make sure you
have the proper equipment, genuine
Alfa Romeo spare parts and the
necessary fluids; do not however
carry out these operations if you
have no experience.
WARNING
Pollen filter
If the car is used frequently in dusty or
heavily polluted environments it is advisable
to replace the filtering element more fre-
quently; in particular it should be replaced if
a reduction of the amount of air admitted to
the passenger compartment is noted. WARNING
Battery
You are recommended to have the battery
charge conditions checked, preferably at the
onset of winter, to avoid the possibility of
freezing the electrolyte.
This check should be carried out more fre-
quently if the car is used prevailingly for
short journeys, or if it is fitted with services
that absorb high amounts of current per-
manently with the ignition key off, especially
if installed in the after market.
In the case of use of the car in hot climates
or particularly harsh conditions, it is wise
to check the level of the battery fluid (elec-
trolyte) at more frequent intervals than stat-
ed in the Scheduled Maintenance Pro-
gramme.

CAR MAINTENANCE

WARNINGBrake and hydraulic clutch
fluid is hygroscopic (i.e. it absorbs moisture).
For this reason, if the car is mainly used in
areas with a high degree of atmospheric hu-
midity, the fluid should be replaced at more
frequent intervals than specified in the
Scheduled Maintenance Programme.

When loosening the reser-
voir cap do not allow the
fluid to come into contact
with painted parts. If it does, wash
it off immediately with water.
Brake and clutch fluid is
poisonous and highly cor-
rosive. In the event of accidental
contact, wash the parts involved
immediately with neutral soap and
water, then rinse thoroughly. See
a doctor at once if the fluid is swal-
lowed.

USEFUL HINTS TO EXTEND
THE LIFE OF YOUR BATTERYTo avoid quickly draining the battery and
to preserve its operating conditions over the
course of time, carefully follow the instruc-
tions below:
– The terminals must always be tightened.
– As far as possible, avoid keeping ser-
vices on for a long time with the engine
stopped (radio, hazard lights, parking lights,
etc.).
– When leaving the car parked in a
garage, make sure that the doors, bonnet,
boot and interior lids are properly shut to
prevent lights from staying on.
– Before doing any work on the electric
system, disconnect the battery negative ter-
minal.– If after purchasing the car, you wish to
install electrical accessories which need a
permanent electrical supply (alarm, hands-
free phone, radio-navigator with satellite an-
ti-theft function, etc.) contact Alfa Romeo
Authorized Services whose qualified per-
sonnel, in addition to suggesting the most
suitable devices from Lineaccessori Alfa
Romeo will be able to evaluate the total
electrical absorption, checking whether the
car’s electric system is able to support the
load required or whether a battery with high-
er capacity is necessary. In fact, these de-
vices continue to absorb current with the
ignition key off (car parked, engine off) and
may gradually drain the battery.
REPLACING THE BATTERYIf required, replace the battery with a gen-
uine spare part having the same specifica-
tions. If a battery with different specifica-
tions is fitted, the service intervals given in
the Programmed Maintenance Schedule in
this section will no longer be valid. Refer
to the instructions provided by the battery
manufacturer.

– Do not check for current in the cables by
short-circuiting the ends.
– If electrical welding is to be carried out
on the body of the car, the electronic con-
trol units must be disconnected or removed
if the work involves the production of high
temperatures.
You are also reminded that services with
high current absorption activated by the user,
such as bottle warmers, vacuum cleaners,
cellular telephone, mini refrigerator, etc. ac-
celerate the battery drainage process if they
are powered with the engine not run-
ningor running at idle speed.
WARNINGIt should also be noted that
improper branches on connectors of the elec-
tric wiring for installing additional equipment
is dangerous, particularly if safety devices
are involved.
ELECTRONIC CONTROL
UNITSWith normal use of the car, no particular
precautions need to be taken.
In the event of work on the electric system
or emergency starting, the instructions giv-
en below must absolutely be adhered to:
– Always switch off the engine before dis-
connecting the battery from the electric sys-
tem.
– If it is necessary to charge the battery,
always disconnect it from the electric sys-
tem.
– When starting in an emergency, only
use an auxiliary battery and not a battery
charger.
– Check that the bias is correct and that
the connections between the battery and
the electric system are in efficient conditions.
– Do not connect or disconnect the ter-
minals of the electronic units while the ig-
nition key is at MAR.

INTERIOR PLASTIC PARTSFor routine cleaning of interior plastic parts
use a soft cloth moistened with water and
neutral soap. Remove grease or persisting
stains using appropriate solvent-free prod-
ucts designed to preserve appearance and
colour of plastic components.
IMPORTANTNever use spirit or petro-
leum to clean the instrument panel or oth-
er plastic parts.
INTERIOR FITTINGSPeriodically check that water is not trapped
under the mats (due to water dripping off
shoes, umbrellas, etc.) which could cause
oxidisation of the sheet metal.
CLEANING SEATS AND FABRIC
AND VELVET PARTS – Use a soft brush or vacuum cleaner to
remove dust. Velvet is cleaned better if the
brush is moistened.
– Rub the seats with a sponge moistened
with a solution of water and neutral deter-
gent. CLEANING LEATHER SEATS– Remove dried on dirt with a lightly
moistened chamois leather or cloth with-
out pressing too hard.
– Remove liquid or grease stains with a
dry absorbent cloth without rubbing. Then
wipe with a soft cloth or chamois leather
with water and neutral soap. If the stain per-
sists, use specific products, carefully follow-
ing the instructions for use
WARNINGNever use spirit or alcohol-
based products.
Never use inflammable
products like fuel oil ether
or rectified petrol for cleaning in-
side the car. The electrostatic dis-
charges generated when rubbing to
clean may cause fire.
WARNING
Do not keep aerosol cans in
the car. There is the risk
they might explode. Aerosol cans
must never be exposed to a tem-
perature above 50°C. The temper-
ature inside the car might go well
beyond that figure when exposed
to the sun’s rays.

AUTOMATIC REAR
GEOMETRY CONTROL(optional for versions/markets
where applicable)
The car is fitted with a semi-bearing hy-
dropneumatic system with built-in self-level-
ling functions (due to an active element in-
corporated in the rear shock absorbers) and
damping, applied to the rear suspensions in-
stead of conventional shock absorbers.
When the car is loaded with passengers
and luggage, the rear geometry lowers in
relation to the rigidity of the spring system
and the load. However, as soon as the car
moves off the system utilises the move-
ments induced on the wheels by the rough-
ness of the road surface to increase its bear-
ing capacity and higher the body up to a
pre-established position that will be kept un-
der any load condition.
SOUND SYSTEM(optional for versions/markets
where applicable)
The fixed sound system, with cassette
player (radio with cassette player) or CD
player with parametric sound equalizer
(radio with CD player) has been designed
to suit the specific characteristics of the
passenger compartment, with a
personalised design that matches the
style of the dashboard. The sound system
instructions for use are described in the
attached supplement.The distance that must be covered to reach
the levelling condition is approx. 2,000 me-
tres and it may vary depending on the road
bottom.
When using the boot, nev-
er exceed the maximum
permissible loads given in the
“Technical specifications” chapter.
The load carried and its arrange-
ment in the boot modify road hold-
ing of the car in any case even if
the geometry is kept constant by
the automatic device.
