It is possible to ask the Alfa Romeo Or-
ganisation for an estimate of the cost of
service coupon operations.
IMPORTANTYou are advised to con-
tact Alfa Romeo Authorized Services in
the event of any minor operating faults,
without waiting for the next service cou-
pon.
IMPORTANTThe programmed main-
tenance coupons are specified by the
Manufacturer. The failure to have them
carried out may invalidate the warranty.GENERALITIES
Perfect performance and the life of eve-
ry car are strictly connected with correct
use of it, but above all on the care with
which routine maintenance operations are
carried out for which new programming
criteria have been adopted owing to prod-
uct development.
The mileage for programmed mainte-
nance coupons is 20,000 km.
It is however wise to remember that the
car still needs routine care such as for in-
stance checking and topping up the
fluids, checking the tyre pressure, etc.
Correct vehicle maintenance is surely
the best way to preserve its performance
levels, safety and environment protection
features and low running costs over the
years.
Also remember that strictly observing
the maintenance instructions given in this
Handbook marked by the symbol
—can be a necessary condition for the guar-
antee. If the car is frequently
used for towing trailers,
the interval between
programmed maintenance opera-
tions should be reduced.
Warning, when topping
up never confuse the
various types of fluids
which are incompatible and could
seriously damage the vehicle.

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.

For any topic not specifically dealt with in this chapter,
refer to the main chapter of the Owner’s manual which
should be thoroughly read to ensure that the vehicle is
used correctly and that the maximum performance is
