CORRECT USE OF THE CAR
172
Never leave children un-
attended in the car. Al-
ways remove the ignition
key when leaving the car and take
it with you.To avoid useless con-
sumption of power and
possible draining of the
battery, never leave the ignition
key in the MAR position when the
engine is not running.
PARKING
When the car is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is faced up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a halt if the handbrake
slips.
REDUCING
RUNNING COSTS
AND ENVIRONMENT
POLLUTION
By following a few simple guidelines, it
is possible to save car running costs and re-
duce harmful emissions.
GENERAL CONSIDERATIONS
Car maintenance
To take care of the car maintenance have
the checks and adjustments carried out in
accordance with the “Scheduled Mainte-
nance Programme”.
Tyres
Check the pressure of the tyres routinely
at an interval of no more than 4 weeks: if
the pressure is too low consumption levels
increase as resistance to rolling is higher.
Useless loads
Never travel with an overload in the boot.
The weight of the car (especially in urban
traffic), and its geometry heavily affect con-
sumption levels and stability.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy,
therefore increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels(up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.

CAR MAINTENANCE

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 washer and headlamp wash-
er fluid level
– tyre pressure and conditions.
Every 3000 kmcheck and if necessary
top up the engine oil level.
The use of FL Seleniaproducts is rec-
ommended which have been designed and
made expressly for Alfa Romeo cars (see
“Refuelling” in the “Technical Specifica-
tions” 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 (including spare
wheel)
– Check operation of lighting system
(headlights, direction indicators, hazard
warning lights, boot, passenger compart-
ment, glovebox lights, warning lights, etc.)
– Check operation of windscreen wiper
system, spray jet adjustment
– Check windscreen blade position/wear
– Check front disk brake pad conditions
and wear
– Check cleanness of bonnet and boot
locks, and 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
– Check and if necessary top up fluid lev-
els (engine coolant, brakes, windscreen
washer, battery etc. )
– Change engine oil and oil filter
– Change pollen filter.

CAR MAINTENANCE
234
Alloy rim painting involv-
ing temperatures exceed-
ing 150 °C should be
avoided since wheel mechanical
characteristics could be impaired. Do not cross switch the
tyres, moving them from
the right of the car to the
left and vice versa.Excessive low pressure
causes overheating of the
tyre with the possibility of
serious damage to it.Remember that car road
holding also depends on
correct tyre inflation pres-
sure.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Pro-
gramme. Indeed, ozone, high temperatures
and the prolonged lack of fluid in the sys-
tem may cause hardening and cracking of
the hoses, with possible leaks. Careful con-
trol is therefore necessary.
IMPORTANT NOTES
– Where possible, avoid sudden braking,
tyre squealing starts, violent bumps against
kerbs, potholes or obstacles of various kinds.
Prolonged driving on rough roads may dam-
age the tyres;
– Routinely check the tyres for cuts on the
sides, swellings or uneven tread wear. If nec-
essary contact Alfa Romeo Authorised Ser-
vices;
– Avoid overloading the car when travel-
ling: this may cause serious damage to the
wheels and tyres;
– If a tyre is punctured, stop immediate-
ly and change it to avoid damage to the tyre
itself, the rim, suspensions and steering sys-
tem;
– Tyres age even if they are not used
much. Cracks in the tread rubber are a sign
of aging. In any case, if the tyres have been
on the car for over 6 years, they should be
checked by specialised personnel, to see if
they can still be used. Also remember to
check the compact spare wheel;
– In case of replacement, always fit new
tyres, avoiding those of dubious origin;
