engine Alfa Romeo 159 2006 Owner handbook (in English)

This booklet describes all the versions of the Alfa 159, so you should only consider the infor-
mation concerning the trim level, engine and version purchased by you.
Dear Customer,
thank you for choosing Alfa Romeo.
Your
Alfa 159has been designed to guarantee the safety, comfort and driving pleasure typical of
Alfa Romeo.
This booklet will help you to get to know the characteristics and operation of your car.
The following pages contain all the indications necessary for you to be able to maintain the high standards of per-
formance, quality, safety and respect for the environment which characterize this
Alfa 159.
The enclosed Warranty Booklet also contains the regulations, the warranty certificate and a guide to the services of-
fered by Alfa Romeo.
Services which are essential and precious because, when you purchase an Alfa Romeo you are not only acquiring a
car, but the tranquillity that comes from knowing that an efficient, willing and widespread organization is at your ser-
vice for any assistance problems you may have.
What’s more, every single component of the
Alfa 159is fully recyclable. At the end of your car’s useful lifespan
any Alfa Romeo dealer would be pleased to make arrangements for you car to be recycled
(in compliance with current regulations in force). Nature benefits in two ways: there’s no pollution from waste dis-
posal, and the demand for raw materials is reduced.
Have a good trip.

ALFA ROMEO
CODE SYSTEM
To further protect you car from theft, it
has been fitted with an engine immo-
bilising system. This system is auto-
matically activated when the electronic
key is removed.
An electronic device, in fact, is fitted in
each electronic key grip. The device
transmits a radio-frequency signal when
the engine is started through a special
aerial built into the ignition switch on the
dashboard. The modulated signal, which
changes each time the engine is start-
ed, is the “password”, by means of
which the control unit recognises the
electronic key and enables to start the
engine.
OPERATION
Each time the electronic key is fitted in-
to the ignition switch, the Alfa Romeo
CODE system control unit sends a recog-
nition code to the engine control unit
to deactivate the inhibitor.
SYMBOLS
Special coloured labels have been at-
tached near or actually on some of the
components of your car. These labels
bear symbols that remind you of the pre-
cautions to be taken as regards that par-
ticular component.
The plate summarising the symbols used
fig. 4can be found under the bonnet.

Depending on the markets, the trigger-
ing of the alarm will activate the siren
and the hazard warning lights (for about
26 seconds). The methods of operation
and the number of cycles may vary de-
pending on the versions/markets.
A maximum number of sound/sight cy-
cles is however envisaged. Once the
alarm cycle is over, the system will re-
store its normal operation.
IMPORTANTCentral door unlocking
by the emergency electronic key will not
deactivate the alarm, therefore with
alarm on the siren will activate when
opening one of the doors or the boot.
To deactivate the siren see paragraph
“How to deactivate the alarm”.
IMPORTANTThe engine immobiliser
function is guaranteed by the Alfa
Romeo CODE system, which is auto-
matically activated when the electronic
key is removed from the ignition device.
HOW TO ACTIVATE
THE ALARM
With the doors, bonnet and boot shut
and electronic key removed from igni-
tion switch, point the electronic key in
the direction of the car, then press and
release the button

With the exception of certain markets,
the system sounds a “beep” and the
doors are locked.
Engagement of the alarm is preceded
by a self-diagnostic test characterised by
a different flashing of the driver’s door
ledA-fig. 12: if a fault is detected the
system sounds a further warning
“beep”.
ALARM
(where provided)
WHEN THE ALARM

steering lock operation.
INSTRUMENTS
REV. COUNTER
Rev counter shows engine rpm. The red
zone at the scale bottom indicates that
the engine is running at excessive rpm
dangerous for mechanical components.
Do not drive with the pointer in this area.
IMPORTANTThe electronic injection
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” (rev counter pointer in the red
area) resulting in a gradual loss of en-
gine power, in order to bring engine rpm
below to the safety limit.
The rev counter may, when the engine
is idling, indicate gradual or sudden in-
crease of engine revs as the case may
be; such behaviour is normal and must
not be interpreted as a faulty condition
as it occurs during normal operation, for
instance when climate control or electric
fan are switched on. In particular, slow
revs variation helps keep the battery
charged.
STEERING COLUMN LOCK
Engaging
The steering column lock will engage
5 seconds after removing the electron-
ic key from the ignition device and if the
following conditions are present:
❒engine off;
❒instrument panel off with car at a
standstill;
❒electronic key removed from ignition
device.
Disengaging
The steering column lock will disengage
after fitting the electronic key into the
ignition device.
IMPORTANTSwitching the engine off
when the car is running will not engage
the steering column lock till next switch-
ing off with car stopped. In this event
warning light
>(where provided) on the
instrument panel will come on (or as an
alternative, on certain versions, a sym-
bol and a message are displayed).
IMPORTANTSteering column lock
failure is indicated by the instrument
panel warning light
>(where provid-It is absolutely forbid-
den to carry out what-
ever after-market operation
involving steering system or
steering column modifications
(e.g.: installation of anti-theft
device) that could badly affect
performance and safety, cause
the lapse of warranty and al-
so result in non-compliance of
the car with homologation re-
quirements.
