IN AN EMERGENCY
216
IN THE EVENT OF A FLAT BATTERY
Before anything else, you are advised to
read the precautions for preventing the bat-
tery from draining and for ensuring long life
in the “Vehicle maintenance” chapter.
CHARGING THE BATTERY
IMPORTANTThe battery charging pro-
cedure is described only for information pur-
poses. This operation should be carried out
by Alfa Romeo Authorised Services.
Charging should be slow at a low amp rat-
ing for 24 hours. Charging for a longer time
may damage the battery.Charge the battery as follows:
– Disconnect the battery negative termi-
nal (–).
– Connect the charger cables to the bat-
tery terminals ensuring that the bias is cor-
rect.
– Turn on the charger.
– After charging, turn off the charger be-
fore disconnecting it from the battery.
– Re-connect the battery negative termi-
nal (–).
STARTING WITH AN
AUXILIARY BATTERY
See “Starting with an auxiliary battery” in
this chapter.
Strictly avoid using a bat-
tery charger to start the
engine: you may damage
the electronic systems, in particu-
lar the ignition and fuel supply con-
trol units.
The liquid contained in the
battery is poisonous and
corrosive. Avoid contact with the
skin or eyes. The battery should be
charged in a well ventilated place,
away from naked flames or pos-
sible sources of sparks: danger of
explosion and fire.
WARNING
Do not attempt to charge a
frozen battery: it must
firstly be thawed, otherwise it
may burst. If freezing has occurred,
the battery should be checked by
skilled personnel to make sure that
the internal elements are not dam-
aged and that the body is not
cracked, with the risk of leaking
poisonous and corrosive acid.

ADDITIONAL
OPERATIONS
Every 1000 kmor before long journeys,
check and if necessary top up:
– engine coolant fluid level
– brake/hydraulic clutch control fluid level
– power steering fluid level
– windscreen/rearscreen and headlamp
washer fluid level
– tyre pressure and conditions.
Every 3000 kmcheck and if necessary
top up the engine oil level.
The use of products of the FL Seleniais
recommended which have been designed
and made expressly for Alfa Romeo cars
(see “Refuelling” in the “Technical Specifi-
cations” chapter).
ANNUAL INSPECTION
PROGRAMME
For cars with an annual mileage
of below 20,000 km (for example
about 10,000 km) the following
yearly inspection programme is ad-
vised:
– Check tyre conditions/wear and if nec-
essary adjust the pressure
– Check operation of lighting system
(headlights, direction indicators, hazard
warning lights, boot, passenger compart-
ment, glovebox lights, warning lights )
– Check operation of windscreen wiper
system, spray jet adjustment
– Check position/wear of windscreen/
rearscreen wiper blades
– Check front disk brake pad conditions
and wear
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication– Sight check for conditions of: engine,
gearbox, transmission, pipes (exhaust - fu-
el supply - brakes) rubber parts (boots -
sleeves - bushes etc..), brake and fuel sup-
ply system hoses
– Check battery charge
– Sight check for conditions of various dri-
ve belts

els (engine coolant, brakes, windscreen
washer, battery, etc...)

IMPORTANT
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– frequently idling engines or long distance
low speed driving or in case of a long term
inactivity
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero replace engine oil more frequent-
ly than required on Service Schedule.
IMPORTANT
Air cleaner
Using the car on dusty roads change the
air cleaner more frequently than specified in
the Scheduled Maintenance Programme.
For any doubts concerning the intervals be-
tween engine oil and air cleaner replacement
in relation to how the vehicle is used, con-
tact Alfa Romeo Authorised Services.IMPORTANT
Battery
It is advisable to check the battery charge,
preferably at the onset of winter, to prevent
the possibility of the electrolyte freezing.
This check should be carried out more fre-
quently if the car is used mainly for short
trips, or if it is fitted with accessories that
permanently absorb electricity even with the
ignition key removed, especially in the case
of after market accessories.
If the vehicle is used in hot climates or par-
ticularly harsh conditions it is wise to check
the level of the battery fluid (electrolyte)
more frequently than specified in the Sched-
uled Maintenance Programme.Vehicle maintenance should
be entrusted to Alfa Romeo
Authorised Services. For
routine and minor maintenance op-
erations you wish to carry out your-
self, always make sure you have the
proper equipment, genuine Alfa
Romeo spares and the necessary flu-
ids;do not however carry out these
operations if you have no experi-
ence.IMPORTANT
Pollen filter
If the vehicle 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.

care not to confuse the var-
ious types of fluids: they
are all incompatible with one an-
other and could seriously damage
the vehicle.
Never smoke while work-
ing in the engine compart-
ment; gas and inflammable vapours
may be present, with the risk of
fire.
WARNING

VEHICLE MAINTENANCE
227
Used engine oil and filter
contain harmful substances
for the environment. Con-
tact Alfa Romeo Authorised Ser-
vices, to have the oil and filter
changed as they are equipped to
dispose of the waste oil and filters
respecting nature and the law.
ENGINE OIL (fig. 3)
The engine oil should be checked with the
vehicle on a level surface a few minutes
(about 5) after the engine has been
switched off.
Remove the dipstick (A) clean it, put it
back in completely, remove it and check that
the level is within the MINandMAX
marks on the dipstick. The interval between
theMINandMAXmarks corresponds to
about one litre of oil.If the oil level is near or even below the
MINmark, add oil through the filler neck
(B), until reaching the MAXmark.
IMPORTANTIf a routine check reveals
that the level is above the MAXmark, con-
tact Alfa Romeo Authorised Services to have
the correct level restored.
IMPORTANTAfter topping up the oil,
before checking the level again, run the en-
gine a few seconds and wait for a few min-
utes after stopping it.Engine oil consumption
Max engine oil consumption is usually 400
grams every 1000 km.
During the initial period of use the engine
settles, therefore engine oil consumption
may be considered stabilised only after the
first 5000 ÷ 6000 km.
IMPORTANTEngine oil consumption de-
pends on the way of driving and the condi-
tions of use of the vehicle.

Do not add oil with spec-
ifications (classification,
viscosity) other than those
of the oil already in the engine.
When the engine is hot,
take care when working
inside the engine compartment to
avoid burns. Remember that when
the engine is hot, the fan may cut
in: danger of injury.

SELESPEED TRANSMISSION
OIL
(fig. 4)
The Selespeed transmission oil should be
checked with the vehicle on a level surface
and with the engine stopped and cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and re-
move the cap (A) checking that the level
corresponds with the MAXmark on the dip-
stick integrated with the cap;– if the oil is below the MAXmark, top
up to reach the correct level;
– after refitting the cap, insert the breather
tube firmly on the housing on the cap and
turn the ignition key to STOP.
Used gearbox oil contains
dangerous substances for
the environment. For chang-
ing the oil we advise contacting Al-
fa Romeo Authorised Services who
are equipped for disposing of used
oil respecting nature and the law.Do not add oil with spec-
ifications other than that
already in the gearbox.

Be very careful working in-
side the engine compart-
ment if the engine is hot: danger of
burns. Remember that the fan may
cut in if the engine is very hot: dan-
ger of injury.
