D - Rev counter
The danger zone (red) indicates exces-
sively high engine revs. Do not drive for
long periods with the pointer in this area.
With the engine at idle speed, the rev
counter may indicate a gradual or sudden
speed increase depending on the cases;
this is normal as it occurs in the normal
operation, for example when the climate
control compressor is engaged or the fan.
In particular a slow change in speed helps
preserve the battery charge.
IMPORTANT Depending on the ver-
sions/markets of the car, the rev counter
may have danger sectors (red) of differ-
ent size and with different top of scale
values.
IMPORTANT The electronic ignition
control system gradually shuts off the
flow of fuel when the engine is “over-
revving” resulting in a gradual loss of en-
gine power. Moving the ignition key to MARthe
following warning lights and displays turn
on and go out after approx. 6 seconds:
1- Light failure
2- Low brake fluid and/or handbrake
engaged
3- Front brake pad wear
4- Low engine oil level
5- Fuel reserve
6- Maximum engine coolant fluid tem-
perature
7- Mileage recorder displayAny faults are signalled by the turning
on of the corresponding warning light for
approx. 15 seconds after the end of the
check.
2) Doors and boot open warning.
With the ignition key at MAR, if a led
of the car symbol (10) lights up, the cor-
responding door or the boot has not been
shut properly.
To repeat the check, with the ignition
key in the MARposition and the engine
off, press the button (A-fig. 84).

G - The warning lights
IMPORTANT The presence of the
warning lights may vary depending on
the type of engine and trim level.
Insufficient brake fluid
and/or handbrake on
This warning light stays on for about 15
seconds, after the end of the check,
when the level of the brake fluid falls be-
low the minimum, possibly due to a leak-
age in the system and when the hand-
brake is engaged.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 6 seconds.
x
Air bag malfunction
When the ignition key is turned to the
MARposition the warning light will
come on and should go out as after
about. 4 seconds.
This warning light will come on perma-
nently when an anomaly affecting the Air
bag system is detected.¬
If the ¬warning light
does not turn on when
turning the ignition key to MAR or
if it stays on when travelling, this
could indicate a failure in safety re-
taining systems; under this condi-
tion air bags or pretensioners could
not trigger in the event of collision
or, in a restricted number of cases,
they could trigger accidentally.
Stop the car and contact Alfa
Romeo Authorized Services to
have the system checked immedi-
ately.
WARNING
If the warning light
comes on while driving
check if the handbrake is not en-
gaged. If the warning lights stays
on with the handbrake not engaged,
stop immediately and contact Alfa
Romeo Authorized Services.x
WARNING

116
BRAKE ASSIST (Brake assist in
an emergency)
This system, that cannot be cut out, rec-
ognizes emergency braking on the
ground of the brake pedal operation
speed and allows to speed up the braking
action.
On versions fitted with VDC system,
Brake Assist is deactivated in the event of
VDC system failure (indicated by the
switching on of the relevant warning
light).
The turning on of the>
warning light with the
engine running normally indicates
an ABS system fault. In this case
the braking system preserves its
effectiveness, without however
making use of the antilock device.
Under these circumstances, the EBD
system may fail to give top perfor-
mance. In this case, too, you are
recommended to contact Author-
ized Alfa Romeo Services immedi-
ately driving in such a way as to
avoid abrupt braking, to have the
system checked.
WARNING
If the xlow brake fluid
level warning light comes
on, stop the car immediately and
contact the nearest Authorized Al-
fa Romeo Services. Indeed, any
leak of fluid from the hydraulic
system compromises the effective-
ness of both the conventional
brake system and the system with
antilock system.
WARNING

DRIVING UNDER ADVERSE
WEATHER CONDITIONS
Rain and fog can be extremely danger-
ous if the style of driving is not adapted
to suit these conditions. Some sugges-
tions are given below:
– if the road is wet, the friction be-
tween wheel and asphalt is greatly re-
duced thus increasing the stopping dis-
tance and decreasing road holding when
cornering.
Reduce speed and keep further back
from the vehicle in front.
– Heavy rain and fog reduce visibility.
Headlights should be switched on as the
road traffic laws and common sense dic-
tate, above all to render yourself visible
to others.
– Do not drive over puddles or flooded
roads at high speed as the aquaplaning
phenomenon may cause you to loose
control over the vehicle.
– If visibility is already reduced prevent
it from worsening by ensuring that the
windows do not steam up. Use the heat-
ing-ventilation controls as indicated in the
chapter “Know your vehicle”.– Check the condition of the windscreen
wiper blades.
– If fog is very thick avoid travelling
where possible. If travelling cannot be
avoided drive with extreme care and
moderate your speed. Avoid overtaking.
– If the vehicle is forced to stop owing
to a malfunction or zero visibility condi-
tions, pull off the road, switch on the haz-
ard warning lights and if possible, the
dipped-beam headlights.
MOUNTAIN DRIVING
Mountain driving requires a greater de-
gree of concentration. Some practical
hints follow:
– Before driving off check the level of
fluids (engine oil, brakes, coolant) and
the state of the tyres.
– When travelling down hill use the en-
gine braking by engaging lower gears to
prevent the brakes from overheating.
– Never coast downhill with the engine
off or in neutral and especially not with
the ignition key removed.
– Drive at a moderate speed and avoid
cutting corners.– Remember that overtaking uphill is
slower and therefore requires a greater
length of clear road. If you are being
overtaken on a hill move over to enable
the other vehicle to pass in safety.
WINTER DRIVING
If the temperature falls below 0°C or in
the presence of snow or ice the following
recommendations should be followed:
– Before driving off check that the
windscreen wipers are not frozen to the
windscreen.
– Remove the snow from the air intake
(grille) at the base of the windscreen.
– Do not stop long on deep snow with
the engine running: the snow might di-
vert the exhaust gas carbon monoxide in-
to the passenger compartment.
– Ensure that brakes and tyres are in
perfect working order.
–Ensure that the detergent liquid locat-
ed in the windscreen/headlight washers
has been topped up with anti-freeze and
anti-scale additives.
– Use engine braking where possible
and avoid abrupt braking.

140
– During cold weather even apparently
dry roads may be covered with occasion-
al patches of ice. Pay great attention
therefore when driving on roads which
are in the shade, or where rocks or trees
line the road and on which ice may per-
sist.
IMPORTANT To avoid damaging
tyres do not drive on bare patches of as-
phalt with snow chains fitted to the vehi-
cle. In extreme cases proceed slowly and
remove the chains as soon as possible.
When driving on snow with snow chains
fitted, it might be helpful to turn off the
ASR function of the VDC system (if pre-
sent): in fact, in these conditions, skid-
ding of the driving wheels when moving
off makes it possible to obtain higher
traction.
BRAKES
An efficient braking system is vital to
the safety of the vehicle and its passen-
gers.
To use the brakes correctly and to im-
prove their efficiency and limit wear the
following recommendations should be fol-
lowed:– Do not drive with your foot resting on
the brake pedal.
– Ensure that the brake pedal is not
blocked by the mat or other objects.
– Check the efficiency of the braking
system especially before long journeys.
– Check the handbrake and brake fluid
minimum level warning light
xon the
instrument panel. if the
xwarning light
comes on and stays on when the vehicle
is travelling check that the handbrake is
not engaged. If it is not, stop the vehicle
immediately and check the level of the
brake fluid. If the level is low the anom-
aly affecting the circuit should be rectified
immediately. If the
dwarning light
comes on when the brake pedal is
pressed, this means that the front brake
pads have reached the minimum permit-
ted thickness. Have them replaced as
soon as possible by Alfa Romeo Autho-
rized Services.
– The brake fluid is hygroscopic (i.e. it
absorbs humidity). To prevent the onset
of braking anomalies it should therefore
be replaced every two years regardless of
the kilometres travelled.
SERVO BRAKE
The vehicle is equipped with a servo-
braking system (active only when the en-
gine is running). When the engine is sta-
tionary a greater effort is required to de-
press the brake pedal in order to obtain
the same braking effect.
ANTI WHEEL-LOCK SYSTEM
(ABS)
The vehicle is equipped with an ABS sys-
tem with electronic braking device (EBD),
the following should be heeded:
– A slight pulsing may be felt on the
brake pedal caused by the intervention of
the ABS system.
– The performance of the system, in
terms of active safety, should not induce
the driver to take unnecessary and unjus-
tified risks.
– The conduct of the driver must always
reflect weather, road and traffic condi-
tions.
– Deceleration always depends on the
degree of grip between the tyres and the
road surface. Obviously road holding is

155 VEHICLE INACTIVITY
If the vehicle is to be left inactive for
long periods the following precautions
should be noted:
– House the vehicle under a cover in a
dry and possibly ventilated place.
– Engage a gear.
– Release the handbrake.
– Clean and protect the paintwork by
applying silicon wax.
– Cover the rubber windscreen wiper
blades with talcum powder and raise
them off the glass.
– Open the windows slightly.
– Cover the vehicle with a cloth or per-
forated plastic cover. Do not use compact
plastic covers which prevent the humidity
on the surface of the vehicle from evapo-
rating.
– Inflate the tyres to a pressure of 0.5
bars above normal. If possible rest the
tyres on wooden planks and periodically
check the pressure.– Switch off the alarm system (if fit-
ted) with the remote control, then deacti-
vate it with the emergency key.
– Disconnect the terminals from the
battery poles (negative pole first) and
check the battery charge. When the vehi-
cle is in storage, this check should be car-
ried out once a month. If the no-load volt-
age is less than 12.5V, recharge the bat-
tery.
REMOVING FROM STORAGE
Before using your vehicle after a long
period of inactivity the following opera-
tions should first be carried out:
– Do not dust the outside of the vehi-
cle.
– Visually check that there are no
leaks (oil, brake and clutch fluid, engine
coolant etc.).
– Replace the engine oil and filter.
– Check:
Gearbox-differential oil level
Brake-clutch fluid level
Level of engine coolant fluid.– Check the air cleaner and replace if
necessary.
– Check tyre pressure and ensure that
they are not damaged, cracked or cut. If
they are they must be replaced.
– Check the state of the drive belts in
the engine bay.
– Connect the cables of the battery af-
ter checking that the charge is adequate.
– Re-activate the alarm system, if fit-
ted, using the emergency key.
– With the gear lever in neutral start
the engine and allow the engine to run
for a few seconds whilst repeatedly
pumping the clutch pedal.
