ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the VDC system. It intervenes automatical-
ly if one or both of the drive wheels is slipping, there is a loss in
grip on a wet surface (aquaplaning), acceleration on slippery, snow-
covered or icy surfaces, etc.
Depending on how slippery the road is, two different control sys-
tems are activated:
❍if the slipping involves both drive wheels, the ASR intervenes
reducing the power transmitted by the engine;
❍if the slipping only involves one of the drive wheels, the ASR
intervenes automatically braking the wheel that is slipping.
In order for the ESP and ASR systems to operate
correctly, it is essential that the tyres are of the
same brand and type on all wheels, in perfect con-
dition and, above all, of the specified type, brand and size.
If the space saver wheel is used, the VDC system
keeps operating. Be aware however that the space
saver wheel, being smaller than the original wheel,
provides less grip.
The performance of the VDC and ASR systems
should not encourage the driver to take unneces-
sary risks. Your driving style should always take
road conditions, visibility and traffic into account. The dri-
ver is always ultimately responsible for road safety.

SNOW TYRES
Use snow tyres of the same size as the normal tyres provided
with the car. Alfa Romeo Authorized Services will advise you on the
most appropriate tyre for use.
Only use these tyres in the event of ice or snow on the roads.
For the type, pressures and specifications of the snow tyre to be
used, follow carefully the instructions given in the “Wheels” para-
graph of the “Technical specifications” chapter.
The performance of these tyres is considerably reduced when the
tread depth is less than 4 mm. If this is the case, replace them.
Due to their specific features, the performance of snow tyres is
much lower than that of standard tyres in normal conditions or on
long motorway stretches. You should therefore use them only in
the conditions for which they were designed. All four tyres should be the same (brand and track) to ensure greater
safety when driving, during braking and better driveability. Re-
member that it is inappropriate to change the direction of rotation
of tyres.
The maximum speed for snow tyres marked “Q”
is 160 km/h, while it is 190 km/h for “T” tyres
and 210 km/h for “H” tyres. You should, howev-
er, always stick to the speed limits of the highway code.

Keep your speed down when snow chains are fit-
ted - do not exceed 50 km/h. Avoid potholes, steps
and pavements and also avoid driving for long dis-
tances on roads not covered with snow to avoid damag-
ing the car and the road surface.
SNOW CHAINS
The use of snow chains should be in compliance with local regu-
lations. Snow chains may be fitted only to the front wheel tyres
(drive wheels).
Check the tension of the chains after the first few metres have been
driven.
Use reduced bulk snow chains:
– All versions: for 195/55 R16”, 205/55 R16” and 225/45
R17” size tyres use low-clearance snow chains with a maximum
protrusion beyond the tyre profile of 9 mm.
IMPORTANT The space-saver wheel cannot be fitted with snow
chains. If a front (drive) wheel is punctured and snow chains must
be used, you must remove a normal wheel from the rear and re-
place this one with the space-saver wheel. In this way, with two
normal drive wheels, it is possible to use snow chains.
STORING THE CAR
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❍park the car in a dry, covered and, if possible, ventilated area;
engage a gear and check that the handbrake is not engaged;
❍disconnect the negative battery terminal and check battery
charge. Repeat this check once every three months during stor-
age;
❍clean and protect painted areas using protective wax;
❍clean and protect the shiny metal areas using special com-
mercially-available products;
❍sprinkle talcum powder on the rubber windscreen and rear win-
dow wiper blades and lift them off the glass;
❍slightly open the windows;
❍cover the car with a fabric or perforated plastic sheet. Do not
use compact plastic sheets which do not allow humidity to evap-
orate from the surface of the car.
❍inflate tyres to a pressure of +0.5 bar above the normal spec-
ified pressure and check the pressure at regular intervals;
❍if you have not disconnected the battery, check the battery
charge every thirty days;
❍do not drain the engine cooling system.
