The correct support points for raising
the front and rear part of the car are
illustrated in fig. 101 and fig. 102.
IMPORTANT When positioning the car
on the arm lift, remember that the power
unit is located at the rear end, with
consequent impact on weight
distribution. Therefore, the shorter arms
must support the rear end, and the
longer arms support the front end.

BODYWORK
PROTECTION FROM ATMOSPHERIC
AGENTS
The car features advanced technological
solutions for effective protection of the
exterior bodywork and structure.
The best products and best painting
systems lend the exterior bodywork
particularly high resistance to
atmospheric agents (solar radiation, acid
rain, etc.) and gravel, through specific
protections.
The chassis too, in light,
corrosion-resistant alloy, is treated to
prevent the formation of surface
oxidation.
CAR CORROSION WARRANTY
Your car is covered by warranty against
perforation, due to rust, of any original
element of the structure. For the general
terms of this warranty, refer to the
Warranty Booklet.
22)Be careful to position the lift arms
correctly at the points illustrated, in order
to prevent damage to the carbon fibre
chassis and the bodywork components.
23)To avoid damage to the carbon fibre
chassis, the car cannot be raised with
standard hydraulic jacks, only with
suitable lowered hydraulic jacks.
Contact a dedicated Alfa Romeo
Dealership.

PRESERVING THE BODYWORK
Paint
24) 25)
6)
Touch up abrasions and scratches
immediately.
Maintenance of paintwork consists of
washing the car: the frequency depends
on the conditions and environment
where the car is used.
For example, in highly polluted areas, or
if the roads are spread with salt, it is
advisable to wash the car more
frequently.
To correctly wash the car, proceed as
follows:
❒ wash the bodywork using a low
pressure jet of water. It should be
remembered that the build up of water
can damage the car over a period of time;
❒ use a sponge to wipe a slightly soapy
solution over the bodywork, frequently
rinsing the sponge;
❒ rinse well with water and dry with a jet
of air or leather pad.
When drying take care to dry the least
exposed parts where the water could
collect most easily. The car should not be
taken to a closed area immediately, but
left outside so that residual water can
evaporate.
Do not wash the car after it has been left
in the sun or with the tailgate hot: this
may alter the shine of the paintwork.
Exterior plastic parts must be cleaned in
the same way as the rest of the vehicle.
IMPORTANT NOTES
❒ Avoid parking under trees as much as
possible; the resin from trees dulls the
paintwork.
❒ Bird droppings must be washed off
immediately and thoroughly as the acid
they contain is particularly aggressive.Windows
Use specific detergents and clean cloths
to prevent scratching or altering the
transparency.
Front headlights
Use a soft cloth soaked in water and
detergent for washing cars.
IMPORTANT Never use aromatic
substances (e.g.: petrol) or ketones
(e.g.: acetone) for cleaning front
headlight plastic lens.
IMPORTANT When cleaning the car with
a pressure washer, keep the water jet at
least 20 cm away from the headlights.
Engine compartment
At the end of the winter the engine
compartment should be carefully
washed, without directing the jet against
any electronic control unit. Have this
operation performed at a specialised
workshop.

132)
SEATS AND FABRIC OR
MICROFIBRE PARTS
Remove dust with a soft brush or a
vacuum cleaner.
For cleaning microfibre upholstery
(on some versions, including steering
wheel).
It is advisable to moisten the brush.
Rub the seats with a sponge moistened
with a solution of water and neutral
detergent.
LEATHER SEATS
(where provided)
Remove the dry dirt with a chamois or
slightly damp cloth, without exerting too
much pressure.
Remove any liquid or grease stains using
an absorbent dry cloth, without rubbing.
Then clean with a soft cloth or buckskin
cloth dampened with water and mild
soap. If the stain persists, use specific
products and observe the instructions
carefully.
IMPORTANT Never use alcohol.
Make sure that the cleaning products
used contain no alcohol or alcohol
derivatives, even in small quantities.
PLASTIC, CARBON AND
COATED PARTS
Clean interior plastic and visible carbon
parts with a damp cloth (if possible made
from microfibre), and a solution of water
and neutral, non-abrasive detergent.
To clean oily or persistent stains, use
specific products free from solvents and
designed to maintain the original
appearance and colour of the
components.
Remove any dust using a microfibre cloth,
if necessary moistened with water.
The use of paper tissues is not
recommended as these may leave
residues.
26)
LEATHER UPHOLSTERY
(for versions/markets, where provided)
Use only water and mild soap to clean
these parts. Never use alcohol or
alcohol-based products.
Before using a specific product for
cleaning interiors, make sure that it does
not contain spirit and/or alcohol based
substances.
130)Never use flammable products, such
as petroleum ether or modified petrol, to
clean the inside of the car. The
electrostatic charges which are
generated by rubbing during the cleaning
operation may cause a fire.
131)Do not keep aerosol cans in the car:
danger of explosion.
Aerosol cans must not be exposed to a
temperature exceeding 50°C.
When the vehicle is exposed to sunlight,
the internal temperature can greatly
exceed this value.
132)It is essential that there is nothing
under the pedals: make sure the mats are
lying flat and do not get in the way of the
pedals.
IMPORTANT
26)Never use alcohol, petrols and
derivatives to clean the dashboard and
instrument panel lens.

30)
Use of specific products is recommended
for washing the soft top cloth.
The soft top fabric is treated with a
special water-repellent, waterproof
product.
The water-repellent properties will
degrade in time with exposure to the
weather elements. Observe the following
instructions for washing:
it is recommended to wash by hand.
Remove as much dirt from the surface of
the soft top with a soft brush or vacuum
cleaning before washing it.
This operation will considerably improve
the final result.
In lack of specific products, use water
and mild soap applied with a sponge
(preferably in the shade) for washing.
Rinse the soft top with clean water after
having eliminated all the stains.
Leave the car in the shade after washing
avoiding direct sunlight.
Waterproofing the top
31)
Use specific waterproofing products for
fabric soft-tops.
Interior top fabric
Remove dust with a soft brush.
Avoid using hard brushes made of
synthetic material to prevent damaging
the fabric beyond repair.
Clean the surface with a microfibre cloth
or soft sponge dipped in a solution of
water and mild soap. Clean the entire
surface, including the zones where
cleaning is not needed, to prevent haloes
or staining.
Use common, car care mild stain
removers for more stubborn stains.
Apply by blotting (never rubbing) directly
on the area of the stain.

IMPORTANT INFORMATION AND RECOMMENDATIONS
CIGAR LIGHTER
The cigar lighter gets very hot. Handle it carefully and make sure that children don’t use it: risk of fire and/or burns.
ASHTRAY
Do not use the ashtray as a waste paper basket: it may catch fire in contact with cigarette stubs.
WHEELS AND TYRES
The road holding qualities of the car also depend on the correct inflation pressure of the tyres. If tyre pressure is too low, the tyre may
overheat and be severely damaged as a result.
Do not switch tyres from the left to the right side and vice versa, in order to prevent inversion of the rotation direction.
Do not repaint alloy wheel rims at temperatures higher than 150°C.
The mechanical characteristics of the wheels might be compromised.
The car is always equipped with front and rear wheels of different dimensions. It is not therefore possible to move the wheels from the
front to the back and vice versa.
ACCESSORIES PURCHASED BY THE OWNER
Take care when fitting additional spoilers or non-standard alloy wheels: they could reduce the ventilation of the brakes and affect
efficiency in sharp, repeated braking or on long descents. Make sure that nothing obstructs the pedal stroke (mats, etc.).
CATALYTIC SILENCER
Under operating conditions, the catalytic converter becomes very hot. Therefore, do not park the car on flammable materials
(grass, dry leaves, pine needles etc.) to avoid the risk of fire.
