GENERAL INSTRUCTIONS
❒ Check that the corresponding
contacts are not oxidised and that the
corresponding fuse is intact before
changing the bulb. For the location of
fuses, refer to the paragraph “If a fuse
blows” in this chapter.
❒ replace blown bulbs with others of the
same type and power;
❒ after replacing a headlight bulb,
always check its alignment.
IMPORTANT When the weather is cold or
damp or after heavy rain or after
washing, the surface of headlights or rear
lights may steam up and/or form drops of
condensation on the inside. This is a
natural phenomenon due to the
difference in temperature and humidity
between the inside and the outside of the
glass which does not indicate a fault and
does not compromise the normal
operation of lighting devices. The mist
disappears quickly turning the lights on,
starting from the centre of the diffuser,
extending progressively towards the
edges.
85)The use of hazard warning lights is
governed by the Highway Code of the
country you are driving in: comply with
legal requirements.
IMPORTANT
86)Modifications or repairs to the
electric system that are not carried out
properly or do not take the system
technical specifications into account can
cause malfunctions leading to the risk of
fire.
87) Halogen bulbs contain pressurised
gas, in the case of breakage they may
burst causing glass fragments to be
projected outwards.
88) Due to the high supply voltage, gas
discharge bulbs (Bi-Xenon) should only be
replaced by specialised personnel: danger
of death! Contact a dedicated Alfa Romeo
Dealership.
IMPORTANT
9)Halogen bulbs must be handled by
holding the metallic part only. Touching
the transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan
of the bulb. In the event of accidental
contact, wipe the bulb with a cloth
moistened with alcohol and let the
bulb dry.

 Visually inspect condition of the accessory drive belt(s)
Inspect the conditions of toothed timing drive belt
Check handbrake lever travel and adjust, if necessary
(or every 12 months)
Use the diagnosis socket to check supply/engine and
gearbox/transmission management system operation and engine oil degradation
Check and, if necessary, top up oil level for the
twin clutch transmission
Replace spark plugs (1)
Replace accessory drive belt/s
Replace toothed timing drive belt (2)
Replace air cleaner cartridge
Replace engine oil and oil filter (3)
Change brake fluid (or every 24 months)
(1) The following are essential to ensure correct operation and prevent serious damage to the engine: only use spark plugs of the same make and type
which are specially certified for such engines (see the information in the “Engine” paragraph in the “Technical specifications” chapter); strictly
comply with the spark plug replacement interval given in the Scheduled Servicing Plan; for spark plug replacement, it is advisable to contact a
dedicated Alfa Romeo Dealership.
(2) Irrespective of the mileage, the timing drive belt must be replaced every 4 years for heavy-duty use
(cold climates, town use, long periods of idling) or, in any case, every 5 years.
(3) The actual interval for changing the oil and replacing the engine oil filter depends on the car usage conditions and is signalled by the warning light
or message (where provided) or the instrument panel or, in any case, every 12 months.

ENGINE OIL
Check that the oil level is between the
MIN and MAX marks on the dipstick
1 fig. 87.
For this check, take out the dipstick from
its seat, clean it with a lint-free cloth,
reinsert the dipstick; take it out again and
check the oil level.
119)
If the oil level is near or under the MIN
mark, add oil through the filler 2 fig. 87
until it reaches the MAX mark.
15)
Tool 1 shown in fig. 89 and stored in the
car, must be used to
undo and refasten the filler cap.
Take out the engine oil dipstick 1 fig. 87,
clean it with a lint-free cloth  and reinsert
it. Extract the engine oil dipstick again
and check that the level is between the
MIN and MAX marks on the dipstick.
119)
WARNING Make sure that the oil cap is
tightened properly in its seat after
topping the oil up.
After refitting the cap, remove tool 1 fig.
89 before closing the bonnet and place it
back in the housing to prevent misplacing
it and avoid the risk of causing damage to
the engine.
The range between the MIN and MAX
levels corresponds to approximately 1
litre of oil.
89A0L0231
Engine oil consumption
16) 4)
The maximum engine oil consumption is
usually 400 grams every
1000 km.
When the car is new, the engine needs to
be run in; therefore the engine oil
consumption can only be considered
stabilised after the first
5,000 - 6,000 km.
IMPORTANT After adding or changing
the oil, let the engine run for a few
seconds and wait a few minutes after
switching it off before checking the level.
ENGINE COOLANT FLUID
120) 17)
The coolant level must be checked when
the engine is cold and must range
between the MIN and MAX marks on the
reservoir.
If the level is too low, unscrew reservoir
plug 3 fig. 87 and add the fluid described
in the “Fluids and lubricants” paragraph of
the “Technical Specifications” chapter.

COLD TYRE INFLATION PRESSURE (bar)
Tyres provided Inflation pressure (bar)
Front tyres 205/45 R17 88Y XL 1.8 205/40 R18 86Y XL 1.8
Rear tyres 235/40 R18 95Y XL 2.0 235/35 R19 91Y XL 2.0
When the tires are warm, the inflation pressure should be + 0.3 bar in relation to the recommended figure.
However, recheck that the value is correct with the tyre cold.
With snow tyres, add +0.2 bar to the pressure value prescribed for standard tyres.
If it is necessary to raise the vehicle, refer to the “Raising the vehicle” paragraph in the “Servicing and care” chapter.
SNOW TYRES
Use snow tyres of the same size as the normal tyres provided with the car: the dedicated Alfa Romeo Dealership will be able to advise
you on the most appropriate tyre to use.
Only use these tyres in the event of ice or snow on the roads.
In these conditions it is recommended to select the “All Weather” mode of the Alfa DNA system.
For the type of snow tyre to be used, inflation pressures and the specifications of the tyres, carefully follow the instructions given in
this paragraph.
134)
The performance of these tyres on low-grip surfaces are reduced considerably when the tread depth is below 4 mm. Replace them in
this case.
Due to the specific characteristics of snow tyres, in normal weather conditions and dry asphalt or on long motorway journeys, the
performance of these tyres is lower than that of standard tyres.
Their usage should therefore be restricted in accordance with their type approval.
