er uphill or fully laden car): decrease
speed, if the warning light stays on, stop
the car. Wait for 2 or 3 minutes leaving
the engine on and slightly accelerated to
further activate the circulation of the
coolant fluid, then switch the engine off.
IMPORTANTUnder severe use of the
car, keep the engine on and slightly ac-
celerated for few minutes before switch-
ing it off.
Warning light Findi-
cates also warning light
¬failures. This is indicated by
intermittent flashing, over 4
seconds, of warning light

this event warning light
¬could
not indicate safety system fail-
ures. Contact Alfa Romeo Au-
thorized Services to have the
system checked immediately.

If the warning light comes on, proceed
as follows:
–Normal driving conditions: stop
the car, switch off the engine and check
whether the water level in the reservoir
is not below the MINmarl. Otherwise
wait for few seconds to allow engine
cooling, then open slowly and carefully
the cap, top up coolant and check
whether its level is falling between MIN
andMAXmarks in the reservoir. Check

vided) turns on, but it should go off as
soon as the engine has started (with the
engine running at idle speed a brief de-
lay in going out is allowed).

FAILURE
(petrol versions -

Injection system failure
Fitting the key into the ignition device
the warning light turns on, but it should
go off when the engine has started.
The warning light stays on or it turns on
when travelling to indicate a malfunc-
tion in the injection/exhaust system
with possible lack of performance, poor
driveability and high consumption.
In these conditions it is possible to con-
tinue driving without however requiring
heavy effort or high speed from the en-
gine. In any case, contact Alfa Romeo
Authorized Services as soon as possible.EOBD system failure
Under normal conditions, fitting the elec-
tronic key into the ignition device, the
warning light turns on, but it should go
off when the engine has started. This in-
dicates proper operation of the warn-
ing light.
If the warning light stays on or turns on
when travelling:
– glowing steadily (on certain ver-
sions together with the message on the
display): means a fault in the sup-
ply/ignition system which could cause
high emissions at the exhaust, possible
lack of performance, poor handling and
high consumption levels. In these con-
ditions it is possible to continue driving
without however requiring heavy effort
or high speed from the engine. Pro-
longed use of the car with the warning
light on may cause damages. Contact
Alfa Romeo Authorized Services as soon
as possible.
The warning light goes off if the fault
disappears, but it is however stored by
the system.
INCOMPLETE DOOR

display) to indicate that there is water
in the diesel fuel filter.
c
The presence of water in
the fuel circuit may
cause serious damage to
the entire injection system and
cause irregular engine opera-
tion. If the warning light
con
the dial turns on (on certain ver-
sions together with the mes-
sage on the display) contact Al-
fa Romeo Authorized Services
as soon as possible to have the
system relieved. If the above
indications come on immediate-
ly after refuelling, water has
probably been poured into the
tank: turn the engine off imme-
diately and contact Alfa Romeo
Authorized Services.
If, after a crash, you
smell fuel or see leaks
from the fuel system, do not
reset the switch to avoid fire
risk.

the
>andxwarning lights (on cer-
tain versions together with the message
on the display) indicates that the EBD
system is inefficient; in this case heavy
braking may cause the rear wheels to
lock before time, with the possibility of
skidding.
Drive with the utmost care to the near-
est Alfa Romeo Authorized Service to
have the system checked.
VDC SYSTEM
(where provided)
(amber)
Fitting the key into the ignition device
the warning light turns on, but it should
go off after few seconds.
The warning light flashes when the VDC
cuts in, to alert the driver that the sys-
tem is adapting to the road surface grip
conditions.
VDC deactivation
When the VDC is deactivated manually
(pressing the ASR/VDC button for 2 sec-
onds) (see paragraph “VDC system” in
section “Dashboard and controls”) the
instrument panel warning light turns on
(on certain versions a message is dis-
played).
VDC failure
In case of failure, the VDC system will
deactivate automatically and the in-
strument panel warning light
áwill turn
on glowing steadily (on certain versions
a message will also be displayed). In
this case contact Alfa Romeo Authorized
Services as soon as possible.
ABS SYSTEM
FAILURE (amber)
Fitting the key into the ignition
device the warning light turns on, but
it should go off after few seconds.
The warning light turns on (on certain
versions a dedicated message is dis-
played) when the system is inefficient.
In this case the braking system keeps
its effectiveness unchanged, but without
the potential offered by the ABS system.

JUMP STARTING
If the battery is flat, it is possible to start
the engine using an auxiliary battery
with the same capacity or a little high-
er than the flat one.
Proceed as follows fig. 1:
❒ Connect positive terminals (+ near
the terminal) of the two batteries
with a jump lead;
❒ With a second lead, connect the neg-
ative terminal (–) of the auxiliary
battery and to an earthing point
E
on the engine of the car to be start-
ed;
❒Start the engine;
❒When the engine has been started,
remove the leads reversing the or-
der above.If after a few attempts the engine does
not start, do not insist but contact Alfa
Romeo Authorized Service.
IMPORTANTDo not directly connect
the negative terminals of the two bat-
teries: sparks could ignite the flamma-
ble gas from the battery. If the other bat-
tery is fitted in another car, prevent ac-
cidental contacts between the metal
parts of the two cars.
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.
Do not carry out this
procedure if you lack
experience; if it is not done
correctly it can cause very in-
tense electrical discharges. In
addition, the fluid contained in
the battery is poisonous and
corrosive. Avoid contact with
skin and eyes. You are also ad-
vised not to put naked flames
or lighted cigarettes near the
battery and not to cause
sparks.
