Incorrect pressure causes abnormal tyre
wearfig. 15:
Anormal pressure: tread evenly worn.
Blow pressure: tread particularly worn
at the edges.
Chigh pressure: tread particularly worn
in the centre.
Tyres must be replaced when the tread
wears down to 1.6 mm. In any case,
comply with the laws in the country
where the car is being driven.
IMPORTANT NOTES
As far as possible, avoid sharp braking
and screech starts, etc. Be careful not to
hit the kerb, potholes or other obstacles
hard. Driving for long stretches over
bumpy roads can damage the tyres.
Periodically check that the tyres have no
cuts in the side wall, abnormal swelling
or irregular tyre wear. If any of these oc-
cur, have the car seen to at Alfa Romeo
Authorized Services.
Avoid overloading the car when travel-
ling: this may cause serious damage to
the wheels and tyres; if a tyre is punc-
tured, stop immediately and change it
to avoid damage to the tyre, the rim,
suspensions and steering system.
WHEELS AND TYRES
Check the pressure of each tyre, includ-
ing the space-saver spare wheel, every
four weeks and before long journeys:
pressure should be checked with the tyre
rested and cold.
For the correct tyre inflation pressure,
see “Wheels” in “Technical specifica-
tions” section.

Upholstery of your car
has been designed to
withstand wear deriv-
ing from common use of the car.
You are however recommended
to avoid strong and/or contin-
uous scratching with clothing
accessories such as metallic
buckles, studs, Velcro fasten-
ings and the like, since these
items cause circumscribed stress
of the cover fabric that could
lead to yarn breaking, and dam-
age the cover as a consequence.

INTERIOR PLASTIC PARTS
Clean plastic parts with a cloth moist-
ened with water and non-abrasive neu-
tral detergent. To remove grease or hard
stains, use appropriate products de-
signed to preserve the appearance of
components.
IMPORTANTNever use spirit or pe-
troleum to clean the instrument panel
or other plastic parts.
Never use flammable
products like oil ether
or rectified petrol for cleaning
car interiors. Electrostatic dis-
charges generated by rubbing
during cleaning operations
could cause fire.
WARNING
Do not keep aerosol
cans in the car: they
might explode. Aerosol cans
must never be exposed to a
temperature above 50°C. The
temperature inside the car ex-
posed to the sun may go well
beyond that figure.
WARNING
STEERING WHEEL/
GEAR LEVER KNOB WITH

Before using special products for clean-
ing interiors, read carefully label in-
structions and indications to make sure
they are free from spirit and/or alcohol-
based substances.
If when cleaning the windscreen with
special glass products, some drops fall
on the leather covering of the steering
wheel/gear lever knob remove them
immediately and then clean with wa-
ter and neutral soap.
