EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD (European On Board Diagnosis) system is to:
❍to monitor system efficiency;
❍indicate an increase in emissions;
❍to warn of the need to replace deteriorated components.
The car also has a diagnostic connector that can be interfaced
with appropriate tools, which makes it possible to read the error
codes stored in the electronic control units together with a series
of specific parameters for engine operation and diagnosis. This
check can also be carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system com-
pletely, Alfa Romeo Authorized Services are obliged to run tests
and, if necessary, road tests which may also call for a long journey.
DUAL PINION ACTIVE STEERING
This only operates with the key turned to MAR and the engine start-
ed. The steering allows the force required at the steering wheel
to be adjusted to suit driving conditions. The different power as-
sistance modes can be selected via the d,n,a positions of the"Alfa
DNA System" lever (see paragraph entitled "Alfa DNA System").
IMPORTANT The steering system will need to be initialised after
disconnecting the battery. A warning light will come on to indicate
this. Simply turn the steering wheel all the way from one end to the
other or simply drive in a straight line for a few hundred metres.
Under no circumstances should aftermarket op-
erations be carried out involving steering system
or steering column modifications (e.g. installation
of anti-theft device). This could negatively affect perfor-
mance and safety, invalidate the warranty, cause serious
safety problems and also result in non-compliance of the
car with type-approval requirements.

It is advisable not to demand maximum perfor-
mance from your car (e.g. excessive acceleration,
long distances at top rpm, excessively intense brak-
ing, etc.) when it is first used.
Remember that the brake servo and electro-
mechanical power steering are not operational un-
til the engine has been started, therefore much
more effort than usual is required on the brake pedal and
steering wheel.
Never jump start the engine by pushing, towing or
driving downhill. These manoeuvres may damage
the catalytic converter.
When the engine is switched off never leave the
key in the MAR position to prevent useless cur-
rent absorption from draining the battery.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
Proceed as follows:
❍drive off slowly, letting the engine turn at medium speed. Do
not accelerate abruptly;
❍do not demand maximum performance for the first few kilo-
metres. Wait until the engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a taxing drive, before turning the engine off you
should allow it to idle to allow the temperature in the engine com-
partment to fall.
A quick burst on the accelerator before turning off
the engine serves absolutely no practical purpose;
it wastes fuel and is especially damaging to tur-
bocharged engines.

The brake servo and the electrical power steering
will not work while the car is being towed. More
effort on the brake pedal and steering wheel will
therefore be required. Do not use wires for towing. Do not
jerk. Be careful not to damage parts in contact with the
car while towing. Respect the specific rules of the Highway
Code when towing the car, specifically in relation to the
towing device and conduct on the road. Do not start the
engine while towing the car. Clean the threaded seat care-
fully before fastening the hook. Make sure that the hook
is fully fastened in the seat before towing the car.The front and rear tow hooks must only be used
for emergency situations on the road. The car may
be towed for short distances when a dedicated de-
vice is used in compliance with the Highway Code (rigid
bar), and in order to move the vehicle on the road in
preparation for towing by a tow truck. Tow hooks MUST
NOT be used to tow vehicles off the road or where there
are obstacles and/or for towing operations using cables
or other non-rigid devices. Respecting the above condi-
tions, towing must take place with two vehicles (one tow-
ing, the other towed) aligned as much as possible along
the same centre line.
