GENERAL INSTRUCTIONS
❒When a light is not working, check
that the corresponding fuse is intact
before changing a bulb. For the lo-
cation of fuses, refer to the paragraph
“If a fuse blows” in this section;
❒ Before changing a bulb check the con-
tacts for oxidation;
❒ Burnt bulbs must be replaced by oth-
ers of the same type and power;
❒Always check the height of the head-
light beam after changing a bulb.
IMPORTANTThe headlight inner sur-
face may be lightly misted over: this is
not a fault but a natural fact due to low
temperature and the level of air humid-
ity. It will disappear as soon the head-
lights are turned on. The presence of
drops inside the headlights means wa-
ter infiltration, therefore contact Alfa
Romeo Authorized Services.
WHEN NEEDING TO CHANGE A BULB
Modifications or re-
pairs to the electrical
system (electronic control
units) carried out incorrectly
and without bearing the fea-
tures of the system in mind
can cause malfunctions with
the risk of fire.
WARNING
Due to high voltage,
the bulb of (Bixenon)
gas-discharge headlights must
only be replaced by experts:
danger of death! Contact Alfa
Romeo Authorized Services.
WARNING
Halogen bulbs contain
pressurised gas which,
if broken, may cause small
fragments of glass to be pro-
jected outwards.
WARNING
Halogen bulbs must be
handled touching only
the metallic part. If the trans-
parent bulb is touched with the
fingers, its lighting intensity is
reduced and life of the bulb
may be compromised. If
touched accidentally, rub the
bulb with a cloth moistened
with alcohol and allow to dry.

Where possible, do not park under trees;
the resinous substance many species re-
lease give the paint a dull appearance
and increase the possibility of triggering
rust processes.
IMPORTANTBird droppings must be
washed off immediately and thorough-
ly as the acid they contain is particular-
ly aggressive.

MAINTENANCE
To wash the car correctly proceed as fol-
lows:
❒remove the aerial from the roof to
prevent damage to it if the car is
washed in an automatic system;
❒wash the body using a low pressure
jet of water;
❒wipe a sponge with a slightly soapy
solution over the bodywork, fre-
quently rinsing with the sponge;
❒rinse well with water and dry with a
jet of air or a chamois leather.
When drying, take particular care with
the less visible parts like door surrounds,
bonnet and around the headlights where
water may stagnate. The car should not
be taken to a closed area immediately,
but left in the open so that residual wa-
ter can evaporate.
Do not wash the car after it has been left
in the sun or with the bonnet hot: this
may alter the shine of the paintwork.
ADVICE FOR PRESERVING
THE BODYWORK
Paint
Paintwork does not only serve an
aestethic purpose, but also protects the
underlying sheet metal.
In the case of deep scrapes or scores,
you are advised to have the necessary
touching up carried out immediately to
avoid the formation of rust. Use only
original paint products for touching up
(see “Bodywork paint identification
plate” in section “Technical specifica-
tion”).
Normal paint maintenance consists in
washing at intervals depending on the
conditions and environment of use. For
example, in highly polluted areas, or if
the roads are sprayed with salt, it is wise
to wash the car more frequently.
Detergents cause water
pollution. Therefore the
car should be washed
in areas equipped for collecting
and purifying the liquid used in
the washing process.

Front headlights
Front headlights shall be washed with
soft cloth moistened with water and car
detergent.
IMPORTANT Cleaning headlight lens-
es with a dry cloth will damage the
headlights with lack of performance as
a consequence. Solvents mat the lens-
es with lack of performance as a con-
sequence.
IMPORTANT When washing the front
headlights with a water monitor noz-
zle keep at least 2 cm away from the
lenses. Windows
Use specific window cleaner products. Use
also clean cloths to avoid scratching the
glass or damaging the transparency.
IMPORTANTThe inside of the
rearscreen should be wiped gently with
a cloth in the direction of the filaments
to avoid damaging the heating device.Engine compartment
At the end of the winter the engine com-
partment should be carefully washed,
without directing the jet against electronic
control units. Contact a specialised work-
shop to have this done.
IMPORTANT The car should be
washed with the engine cold and the key
removed from the ignition device. After
washing make sure that the various pro-
tections (e.g. rubber caps and various cov-
ers) have not been damaged or removed.
