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.

MAINTENANCE
Remember that road
holding depends also
on the correct tyre inflating
pressure.
WARNING
If the pressure is too
low the tyre overheats
and this can cause it serious
damage.
WARNING
Never submit alloy
rims to repainting
treatments requiring to use
temperatures exceeding
150°C since the mechanical
properties of the wheels could
be impaired.
WARNING
Do not cross switch the
tyres, moving them
from the right of the car to the
left and vice versa.
WARNINGTyres age even if they are not used
much. Cracks in the tread rubber are a
sign of ageing. 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 space-
saver spare wheel.
In the case of replacement, always fit
new tyres, avoiding those of dubious ori-
gin.
If a tyre is changed, also change the in-
flation valve; to allow even wear be-
tween the front and rear tyres, it is ad-
visable to change them over every 10-
15 thousand kilometres, keeping them
on the same side of the car so as to not
reverse the direction of rotation.

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
GENUINE LEATHER
COVERING
These components shall only be cleaned
with water and neutral soap. Never use
spirit or alcohol-based products.
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.
IMPORTANTTake the utmost care
when engaging the steering lock to pre-
vent scratching the leather covering.

IMPORTANTIn the event of difficult disengagement, due to significant difference of grip between front and rear axle, do
not insist with heavy accelerations: it is actually more effective an attempt of disengagement at medium slow engine rpm,
with pauses of a few seconds if several attempts are necessary.

ed on this “Owner’s Manual” and the

A0E0186mfig. 5
On cars fitted with four-wheel drive, all
four tyres should be the same (brand
and track) to prevent damaging the 4-
WD system. The efficiency of the 4-WD
system however, is not jeopardized if
tyres with different wear conditions are
fitted.
Attaining to the prescribed size, to en-
sure safety of the car in movement, it
must be fitted with tyres of the same
make and type on all wheels.
IMPORTANTDo not use inner tubes
with Tubeless tyres.

COLD TYRE INFLATION PRESSURE
Add +0.3 bar to the prescribed inflation pressure when the tyres are warm. Recheck pressure value with cold tyres.
With snow tyres, add +0.2 bar to the inflation pressure value prescribed for standard tyres.
Inflate tyres to full load pressures if driving at continuous speed exceeding 160 km/h.
