2008 Alfa Romeo 166 gas type

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.

Halogen bulbs must be
handled touching only
the metallic part. If the
transparent bulb is touched with
the fingers its lighting intensity
is reduced and the life of the bulb
may be compromised. If touched
accidentally, rub the bulb with a
cloth moistened with methylated
spirits and allow to dry.
Where possible the
bulbs should be re-
placed by Alfa Romeo
Authorized Services. The correct
operation and positioning of the
external lights are vital to the
safety of the vehicle and its pas-
sengers and the subject of specif-
ic laws.
Halogen bulbs contain
pressurised gas, in the
case of breakage they may burst.
WARNING

208
When topping up take
care not to confuse the
various types of fluids:
they are all incompatible and
could seriously damage the car.
If the vehicle is fre-
quently used for towing
trailers, the interval be-
tween one programmed mainte-
nance and the next should be re-
duced.
Vehicle maintenance
should be entrusted to
the Alfa Romeo Service
Network. For ordinary and minor
operations you can do yourself,
always make sure you have ade-
quate tools, original Alfa Romeo
spares and the correct fluids. Do
not carry out these operations if
you have no experience.
Never smoke during
work in the engine com-
partment: there is the possibility
of inflammable gas and vapours
with the risk of fire.

CHECKING AND TOPPING UP
THE WINDSCREEN/HEADLIGHT
WASHER FLUID
(fig. 12-13)
Access to the windscreen/headlight
washer fluid reservoir, remove the cover
(A-fig. 12) after turning the pins (B).
Then remove the cap (C-fig. 13) and
pour the fluid in the tank until the level
can be seen through the filler neck.
Then close the filler with the cap and re-
fit the cover fastening with the two pins.To avoid damaging the
pump motor do not use
the windscreen washers
when the reservoir is empty.

Symbolπon the con-
tainer indicates synthetic
type brake fluid distinguishing it
from the mineral kind. Using min-
eral type fluids damages the spe-
cial rubber braking system gaskets
beyond repair.
WARNING
Brake and clutch fluid is
poisonous and corrosive.
In the event of contact wash the
parts concerned immediately with
neutral soap and water, then rinse
thoroughly. See a doctor at once if
the fluid is swallowed.
WARNING
Some commercial addi-
tives for windscreen
washers are inflammable. The en-
gine compartment contains hot com-
ponents which could set it on fire.
WARNING

226
The characteristics of these products are
compatible with the type of paint, gas-
kets and trim of all Alfa Romeo vehicles.
The application of these products should
however be carried out by Alfa Romeo
personnel who will be able to guarantee
the best results and avoid problems which
may compromise the bodywork warranty
cover.
To correctly wash the car, proceed as fol-
lows:
1) Spray the vehicle with a low pres-
sure jet of water.
2) Pass a sponge moistened with a
light detergent solution (2-4% shampoo
in water) over the bodywork rinsing the
sponge frequently.
3) Rinse well with water and dry with a
jet of air or chamois leather.Detergents cause water
pollution. The car should
therefore be washed in
areas equipped for the collection
and purification of the liquid used
in the washing processes.RECOMMENDATIONS TO
PRESERVE THE BODYWORK
Particular care should be taken to en-
sure that residual deposits of industrial
dust, tar spots, dead insects etc. do not
remain on the bodywork.
Where possible do not park under trees
as, during certain seasons, residues, buds
and leaves containing chemical sub-
stances which are harmful to the paint
may fall onto the vehicle.
When topping up ensure that petrol, lu-
bricating oil, brake fluid, liquid for the
cooling system, battery electrolyte solu-
tion etc. is not splashed onto the body-
work.
If this should occur however, clean the
area immediately and wash the vehicle
as soon as possible.
PAINT
The paintwork does not only serve an
aesthetic 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 by a
specialised workshop to avoid the forma-
tion of rust.
Normal paint maintenance consists in
washing at intervals depending on the
conditions and environment of use.
For example:
– in areas with high atmospheric pollu-
tion.
– Roads sprayed with salt.
– Parking under trees that release
resinous substances.
It is wise to wash the car more frequently.
Alfa Romeo markets a complete series
of products specifically designed for the
care and cleanliness of its vehicles (sham-
poo, wax, touch-up paint stick, stain re-
mover, polish etc.).
