AIR CONDITIONING SYSTEM
MAINTENANCE
90) 91)
To ensure the best possible
performance, the air conditioning
system must be checked and undergo
maintenance at an Alfa Romeo
Dealership at the beginning of the
summer.
WARNING Do not use chemicals to clean
the air conditioning system, since the
internal components may be damaged.
This kind of damage is not covered by
warranty.
Replace the pollen filter
See the "Scheduled servicing plan" for
the correct servicing intervals. For
cleaner replacement, contact an Alfa
Romeo Dealership.
LUBRICATING MOVING PARTS OF THE
BODYWORK
Ensure that the locks and bodywork
junction points, including components
such as the seat guides, door hinges
(and rollers), tailgate and bonnet are
periodically lubricated with lithium-
based grease to ensure correct, silent
operation and to protect them from rust
and wear.
Thoroughly clean the components,
eliminating every trace of dirt and dust.
After lubricating, eliminate excess oil
and grease. Also pay particular attention
to the bonnet closing devices, to ensure
correct operation. During operations on
the bonnet, to be carried out with the
engine cold, also remember to check,
clean and lubricate the locking, release
and safety devices.
Lubricate the external lock barrels twice
a year. Apply a small amount of high-
quality lubricant directly into the lock
barrel.
If necessary, contact an Alfa Romeo
Dealership as soon as possible.
WINDSCREEN WIPER
Periodically clean the windscreen and
rear window and rubber profile of the
windscreen wiper blades, using a sponge
or a soft cloth and a non-abrasive
detergent. This eliminates the salt or
impurities accumulated when driving.
Prolonged operation of the windscreen
window wipers with dry glass may
cause the deterioration of the blades, in
addition to abrasion of the surface of the
glass. To eliminate the impurities on the
dry glass, always operate the windscreen
washers.
In the event of very low outdoor
temperatures, below zero degrees,
ensure that the movement of the rubber
part in contact with the glass is not
obstructed.
Use a suitable deicing product to release
it if required.
Avoid using the windscreen wipers to
remove frost or ice.
Also avoid contact of the rubber profile
of the blades with petroleum derivatives
such as engine oil, petrol, etc.
WARNING The envisaged life of the
windscreen wiper blades varies
according to the usage frequency. In any
case, it is advisable to replace the blades
approximately once a year. When the
blades are worn, noise, marks on the
glass or streaks of water may be noticed.
In the presence of these conditions,
clean the windscreen wiper blades or, if
necessary, replace them.
WARNING Driving with worn windscreen
wiper blades is a serious hazard, because
visibility is reduced in bad weather
conditions.
Raising the windscreen wiper blades
("Service position" function)
The "Service position" function allows
the driver to replace the windscreen
wiper blades more easily. It is also
recommended to activate this function
when it is snowing and to make it easier
to remove any dirt deposits in the
area where the blades are normally
positioned, when washing.
Activation of the function
To activate this function, deactivate the
windscreen wiper (ring fig. 285 in position
