ASR (AntiSlip Regulation) SYSTEM
It is an integral part of the ESC system. It automatically operates in the
event of one or both drive wheels slipping, loss of grip on wet roads
(aquaplaning) and acceleration on slippery, snowy or icy roads, etc.
Depending on the slipping conditions, two different control systems 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.
For the ESC and ASR systems to function correctly, all
four tyres must be the same brand and type, must
be in excellent condition and, above all, must be of the
prescribed type and size.
The ESC system operates even when the space-saver
wheel is being used. Always remember that the
space-saver wheel, being smaller than the original
wheel, provides less grip.
The performance of the ESC and ASR systems must not
encourage the driver to take unnecessary risks. Driving
style must always be adapted to road conditions,
visibility and traffic. The driver is, in any case, responsible for
safe driving.
BRAKE ASSIST (emergency braking
assistance)
The system, which cannot be turned off, recognises emergency braking
(on the basis of the brake pedal operating speed) and speeding up
the response of the braking system. The Brake Assist device is
deactivated if there is a ESC system failure.
MSR (Motor Schleppmoment
Regelung) SYSTEM
This system is an integral part of the ABS, that intervenes, if there is a
sudden downshifting, restoring torque to the engine, thereby
preventing excessive drive at the drive wheels which, especially in poor
grip conditions, could lead to a loss in stability of the car.
CBC (Cornering Brake Control)
SYSTEM
This function improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking on bends if the ABS intervenes. This improves stopping
distances and above all vehicle stability when cornering.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The “Electronic Q2” system uses the braking system to create an effect
similar to a limited slip differential.
The front braking system, when accelerating around a curve, acts on
the inside wheel to increase the drive to the outside wheel (increased
load), dynamically and continuously distributing the torque between
the front drive wheels according to driving and road conditions.
The system, combined with MacPherson front suspension, allows
particularly effective and sports driving to be achieved.

INSTALLING A TOW HOOK
Contact Alfa Romeo Authorised Services to install a tow hook.
The ABS with which the car is equipped will not control
the braking system of the trailer. Particular caution is
therefore required on slippery roads.
Do not, under any circumstances, modify the vehicle's
braking system to control the trailer breaking system.
The towing breaking system must be completely
independent of the vehicle's hydraulic system.
SNOW TYRES
Use snow tyres of the same size as the normal tyres provided with the
car: Alfa Romeo Authorized Services 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.
For the type of snow tyre to be used, inflation pressures and the
specifications, strictly follow the instructions given in the "Wheels"
paragraph in the "Technical specifications" section.
The winter performance of these tyres is considerably reduced when
the tread thickness is less than 4 mm. Replace them in this case.
Due to their specific features, the performance of snow tyres is much
lower than that of normal types in normal conditions or long motorway
stretches. Their usage should therefore be restricted in accordance
with their type approval.
All four tyres should be the same (brand and track) to ensure greater
safety when driving and braking and good driveability. Remember
that it is inadvisable to change the rotation direction 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. The highway code speed limits
must however always be complied with.

SNOW CHAINS
The use of snow chains should be in compliance with local regulations.
The snow chains may be applied only onto the front wheel tyres (drive
wheels).
Check the tension of the snow chains after the first few metres have
been driven.
Use reduced size snow chains: on all versions, for 195/55 R16" and
205/55 R16" size tyres use low-clearance snow chains with a
maximum projection 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 replace this one
with the space-saver wheel. In this way, with two normal drive wheels,
it is possible to use snow chains.
Keep your speed down when snow chains are fitted; do not
exceed 50 km/h. Avoid potholes, steps and pavements
and avoid driving long distances on roads not covered with
snow to avoid damaging the car and the roadbed.
STORING THE CAR
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❒park the vehicle 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 the battery
charge. Repeat this check once every three months during storage;
❒if you have not disconnected the battery, check the battery charge
every thirty days;
❒clean and protect the painted parts using protective wax;
❒clean and protect the shiny metal parts using special compounds
available commercially;
❒sprinkle talcum powder on the windscreen and rear window wiper
rubber blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perforated plastic sheet. Do not use
compact plastic sheets which do not allow humidity to evaporate
from the surface of the car.
❒inflate tyres to +0.5 bar above the standard specified pressure and
check it at intervals;
❒do not drain the engine cooling system.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the battery power supply.
