2013 Alfa Romeo Giulietta technical specifications

WHEELS AND TYRESBefore embarking on a long trip, and every two weeks, check the tyre
inflation pressure and space-saver wheel. Check the tyres when cold.
While driving the car, the pressure increases under standard
conditions: for the correct tyre inflation pressure, see "Wheels"
paragraph in the "Technical specifications" chapter.
Incorrect pressure causes abnormal tyre wear fig. 171:
A normal pressure: tread evenly worn;
B low pressure: tread particularly worn at the edges;
C high pressure: tread particularly worn in the centre.
The tyres must be replaced when the tread is less than 1.6 mm thick.IMPORTANT
Take the following precautions to prevent damage to the tyres:
❒avoid braking suddenly, racing starts and violent impact against the
curb, potholes or other obstacles and driving for extended periods
on uneven road surfaces;
❒periodically check that the tyres have no cuts in the side wall,
abnormal swelling or irregular tyre wear;
❒avoid travelling with the car overloaded. If you puncture a tyre, stop
immediately and replace it;
❒change the position of the tyres every 10-15 thousand kilometres,
keeping them on the same side of the car to avoid inverting the
direction of rotation;
❒tyres age even if they are not used much. Cracks in the tread and on
the sidewalls are a sign of ageing. Have the tyres checked by
specialised personnel if they have been fitted for longer than 6
years. Remember to check the space-saver wheel very carefully;
❒In the case of replacement, always fit new tyres, avoiding those of
dubious origin;
❒if a tyre is replaced, also replace the inflation valve.
Remember that the road holding qualities of your car
also depend on the correct inflation pressure of the
tyres.

If the pressure is too low the tyre overheats and can be
seriously damaged.Do not cross switch the tyres, moving them from the
right of the car to the left and vice versa.Never submit alloy rims to repainting treatments
requiring the use of temperatures exceeding 150°C.
The mechanical properties of the wheels could be
impaired.
WINDSCREEN/REAR WINDOW
WIPERBLADESWe recommend replacing the blades once a year.
A few simple precautions can reduce the possibility of damage to the
blades:
❒if the temperature falls below zero, make sure that ice has not frozen
the rubber against the glass. Use a de-icing product to release it if
required;
❒remove any snow from the window;
❒do not operate the windscreen/rear window wipers on dry glass.
Driving with worn windscreen/rear window wiper
blades is a serious hazard, because visibility is reduced
in bad weather.

Replacing the wiper bladesProceed as follows:
❒raise the wiper arm, press tab A fig. 172 of the attachment spring
and remove the blade from the arm;
❒fit the new blade by inserting the tab into the special slot in the arm.
Make sure that it is properly locked into place;
❒lower the windscreen wiper arm on the windscreen.
Do not operate the windscreen wiper with the blades lifted
from the windscreen.
Lifting the wiper bladesWhen the wiper blades have to be lifted from the windscreen (i.e. in
the event of snow), proceed as follows:
❒turn the ignition key to the MAR position;
❒operate the lever to the right of the steering wheel to activate a
windscreen wiper stroke (see paragraph "Window washing" in
chapter "Getting to know your car");
❒turn the ignition key to the STOP position when the driver's side
wiper blade reaches the windscreen side pillar and lift the
windscreen wiper to the rest position;
❒bring the wiper blades back into contact with the windscreen before
activating the windscreen wiper.

HEADLIGHT WASHERS(for versions/markets, where provided)
They are located inside the front bumper fig. 176.
They are activated when the dipped beam and/or main beam
headlights are on and the windscreen washer is activated.
Check the correct operation and cleanliness of nozzles at regular
intervals.
BODYWORKPROTECTION AGAINST ATMOSPHERIC
AGENTSThe car is equipped with the best available technological solutions to
effectively protect the bodywork against corrosion.
These are the most important:
❒painting products and systems which give the car resistance to
corrosion and abrasion
❒use of galvanised (or pretreated) steel sheets, with high resistance to
corrosion;
❒spraying of plastic parts, with a protective function in the more
exposed points: underdoor, inner wing, edges, etc;
❒use of “open” boxed sections to prevent condensation and pockets of
moisture which could favour the formation of rust inside;
❒use of special films to protect against abrasion in exposed areas
(e.g. rear wing, doors, etc.).BODY AND UNDERBODY WARRANTYThe car is covered by warranty against perforation due to corrosion of
any original element of the structure or body. For the general terms
of this warranty, refer to the Warranty Booklet.

PRESERVING THE BODYWORKPaint
Touch up abrasions and scratches immediately to prevent the formation
of rust.
Maintenance of paintwork consists of washing the car: the frequency
depends on the conditions and environment where the car is used. For
example, it is advisable to wash the car more often in areas with
high levels of atmospheric pollution or salted roads.
To correctly wash the car, follow these instruction:
❒remove the aerial from the roof when using a carwash;
❒if high pressure jets or cleaners are used to wash the car, maintain a
distance of at least 40 cm from the bodywork to avoid damage or
alteration. Bear in mind that a build up of water could cause
damage to the car in the long term.
❒wash the body using a low pressure jet of water;
❒wipe a sponge with a slightly soapy solution over the bodywork,
frequently rinsing the sponge;
❒rinse well with water and dry with a jet of air or a chamois leather.
Dry the less visible parts (e.g. door frames, bonnet, headlight frames
etc.) with special care, as water may stagnate more easily in these
areas. Do not wash the car after it has been left in the sun or with the
bonnet hot: this may alter the shine of the paintwork.
Exterior plastic parts must be cleaned in the same way as the rest of
the car.
Detergents pollute the environment. Only wash your car in
areas equipped to collect and treat wastewater from this
type of activity.
In order to preserve the aesthetic properties of the
paintwork, abrasive products and/or polishes should not
be used to clean the car.
IMPORTANT
Avoid parking under trees; the resin dropped by trees makes the
paintwork go opaque and increases the possibility of corrosion.
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.
IMPORTANT Wipe the inside surface of the rear window gently with a
cloth in the direction of the filaments to avoid damaging the heating
device.
Front headlights
Use a soft, damp cloth soaked in water and detergent for washing
cars.
IMPORTANT Never use aromatic substances (e.g. petrol) or ketenes
(e.g. acetone) for cleaning the plastic lenses of the front headlights.
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 every winter, wash the engine compartment thoroughly,
taking care not to aim the jet of water directly at the electronic control
units or at the windscreen wiper motors. Have this operation
performed at a specialised workshop.
IMPORTANT The washing should take place with the engine cold and
the ignition key in the STOP position. After washing, make sure that the
various protective devices (e.g. rubber caps and guards) have not
been removed or damaged.
INTERIORSPeriodically check for water puddles under the mats that could cause
the panels to rust.
Never use flammable products, such as petrol ether or
rectified petrol to clean the inside of the car. The
electrostatic charges which are generated by rubbing
during the cleaning operation may cause a fire.Do not keep aerosol cans in the car: they might
explode. Aerosol cans must not be exposed to a
temperature exceeding 50°C. When the car is exposed
to sunlight, the internal temperature can greatly exceed this
value.
SEATS AND FABRIC PARTSRemove dust with a soft brush or a vacuum cleaner. It is advisable to
use a moist brush on velvet upholstery. Rub the seats with a sponge
soaked in a solution of neutral detergent and water.

LEATHER SEATS(for versions/markets, where provided)
Remove the dry dirt with a buckskin or slightly damp cloth, without
exercising too much pressure. Remove liquid or oil stains using a dry
absorbent cloth, without rubbing. Then clean with a soft cloth or
buckskin cloth dampened with water and neutral 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 AND COATED PARTSClean interior plastic 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.
IMPORTANT Never use alcohol, petrols and derivatives to clean the
instrument panel lens.LEATHER PARTS(for versions/markets, where provided)
Use only water and neutral 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 alcohol and/or
alcohol based substances.
