PROTECTING EMISSION
REDUCING DEVICESCorrect operation of the antipollution de-
vices not only guarantees respect for the en-
vironment but also influences car perfor-
mance. Keeping these devices in good con-
dition is therefore the first rule for both en-
vironment-friendly and economy driving.
The first precaution is to closely follow the
“Scheduled Maintenance Programme ”. For
petrol engines only use unleaded petrol (95
RON) (specification EN228), for diesel en-
gines only use fuel oil for motor vehicles
(specification EN590).
If difficulty with starting is experienced do
not insist with extended attempts. Especially
avoid bump, tow or coast starts: these may
all damage the catalyst. Only use an auxil-
iary battery to start the car in an emergency.If the engine is “not running smoothly”
when the vehicle is travelling, reduce the re-
quest for performance to a minimum and
contact Alfa Romeo Authorized Services as
soon as possible.
When the fuel reserve warning light comes
on fill up as soon as possible. A low fuel level
may cause an irregular supply to the engine
with inevitable increase of the exhaust gas
temperature; this would result in serious
damage to the catalyst.
Never run the engine, even as a test, with
one or more spark plugs disconnected. Do
not warm the engine at idle speed before
moving off, unless the outside temperature
is very low and, in this case too, for no more
than 30 seconds.
Do not install other heat
guards and do not remove
the existing ones on the catalyst
and exhaust pipe.
WARNING
Do not spray anything on
the catalyst, lambda sen-
sor and exhaust pipe.
WARNING
The failure to follow these
rules may cause a fire
hazard.
WARNING
During normal service the
catalyst reaches high tem-
peratures. Do not therefore park
the car over inflammable materials
(grass, dry leaves, pine needles,
etc.): fire hazard.

INSTALLATION LAYOUT
(fig. 1)
The tow hook structure must be fastened
in the points shown by the symbol
Ø
us-
ing 4 M8 screws and 7 M10 screws.
Inner plate (2) should be at least 6 mm
thick.
Inner plate (3) should be at least 4 mm
thick.
Outer plate (4) should be at least 5 mm
thick.
The fastening points (1) must be fitted
with spacers with 25 mm diameter and 6
mm thickness. For the electrical connection, a 7 pin
12VDC connection is to be used
(CUNA/UNI - 9128 Standard). Follow the
instructions provided by the car manufac-
turer and/or the tow hitch manufacturer.
An electric brake should be supplied directly
by the battery through a cable with a cross
section of no less than 2.5 mm
2. In addition
to the electrical branches, the car’s electric
system can only be connected to the supply
cable for an electric brake and to the cable
for an internal light, though not above 15W.WARNINGIt is compulsory to fasten a
label (clearly visible) of suitable size and
material at the height of the hook ball with
the wording:
MAX. LOAD ON BALL 60 kg
After assembly, the fas-
tening screw holes should
be sealed to prevent the infiltra-
tion of exhaust gas.
WARNING

CORRECT USE OF THE CAR
203
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
VEHICLE INACTIVITYIf the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the vehicle under cover in a dry
and possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the painted parts us-
ing protective wax.
– Disconnect the negative terminal (–)
and check the battery charge. This check is
to be repeated every three months.
Recharge if the optical indicator shows a
dark colour without the central green area.
WARNINGWhere applicable, switch off
the electronic car alarm with the remote con-
trol.– Clean and protect the shiny metal parts
using special compounds readily available.
– Sprinkle talcum powder on the rubber
windscreen and rear window wiper blades
and lift them off the glass.
– Slightly open the windows.
– Cover the car with a cloth or perforated
plastic sheet. Do not use sheets of non-per-
forated plastic as they do not allow mois-
ture on the car body to evaporate.
– Inflate the tyres to 0.5 bar above the
normal specified pressure and check it at in-
tervals.
– If you don’t disconnect the battery from
the electric system, check its charge every
month and recharge it if the optical indica-
tor shows a dark colour without the central
green area.
– Do not drain the engine cooling system. Snow chains cannot be
fitted to the spare wheel
so, if a front (drive) tyre is
punctured and chains must be fit-
ted, the rear wheel should be fit-
ted to the front of the vehicle (in-
flate the tyres to the specified
pressure as soon as possible) and
the spare tyre should be fitted to
the rear. A snow chain can then be
safely fitted to the front wheel.

STARTING WITH AN
AUXILIARY BATTERYIf the battery is flat (for battery with op-
tical hydrometer: dark in colour with no
green area in the centre), the engine can be
started using another battery of the same
or a little higher capacity than the flat one.
This is what you should do fig. 1:
1)Remove the protecting cover on the
battery positive pole by pressing the related
side wings (front side), then connect the
positive terminals (plus sign +next to the
terminal) of the two batteries with a special
cable.
2)Connect a second cable to the negative
terminal (–) of the auxiliary battery with
an earth point
Eon the engine or the gear-
box of the car to be started.WARNINGDo not directly connect the
negative terminals of the two batteries: any
sparks may set fire to the gas that may be
released from the battery. If the auxiliary bat-
tery in installed on another car, no metal part
shall accidentally come into contact with this
car and the one with the flat battery.
3)Start the engine.
4)When the engine is running remove the
cables in reverse order.
If after a few attempts the engine does not
start, do not insist but contact Alfa Romeo
Authorized Services.

Never use a quick battery
charger to start the engine
in an emergency as this
could damage the electronic sys-
tems of your vehicle, particularly
the control units which manage the
starting and supply functions.
The battery terminal con-
necting and disconnecting
operations generate cur-
rent that may cause problems to
the car’s electronic systems. There-
fore, this operation should be car-
ried out by skilled personnel.This starting procedure
must be carried out by
qualified personnel as incorrect op-
erations may provoke electrical
discharge of great intensity. The
liquid contained in the battery is
toxic and corrosive. Avoid contact
with skin and eyes. Keep naked
flame and lighted cigarettes away
from the battery. Do not cause
sparks.

STARTING BY INERTIA
IN THE EVENT OF A
PUNCTUREWARNINGIf the car is equipped with
“Fix&Go kit for tyre quick repair”, see the
instructions contained in the following
chapter.GENERAL INSTRUCTIONSWheel changing and correct use of the jack
and compact spare wheel call for some pre-
cautions as mentioned below. Never push, tow or coast
start the vehicle. This could
cause fuel to flow into the
catalyst damaging it irreversibly.
Remember that the engine
brake and power steering
are not operational until the engine
is started, therefore, much greater
effort than usual is needed on the
brake pedal and steering wheel.
WARNING
Signal the presence of the
stationary vehicle accord-
ing to the current regulations: haz-
ard warning lights, reflecting tri-
angle, etc.
Any passengers should leave the
car and wait for the wheel to be
changed out of harm of the traffic.
If parked on a slope or uneven road
surfaces, place wedges or other
suitable devices under the wheels
to prevent the car from rolling.
Never start the engine when the
car is raised on the jack.
When towing a trailer, always
remove the trailer before lifting
the car.

– Fully tighten the bolts in the sequence
shown in fig. 8, without refitting the cap.REFITTING A NORMAL WHEEL– Following the procedure described pre-
viously, raise the car and remove the spare
wheel.
For versions with steel rims:
– Fit a normal wheel bearing in mind that
the pin (B-fig.7) must match one of the
holes (A-fig.7).
– Make sure that the contact surfaces of
the compact spare wheel with the hub are
clean and free of impurities which may lat-
ter cause the fastening bolts to slacken.– Screw the fastening bolts.
– Tighten the bolts following the order pre-
viously described for the compact spare
wheel fig. 7.
– Place the cap near the wheel so that the
inflating valve can come out through the
countersunk hole. Press the wheel circum-
ference starting from the area next to the
valve countersunk hole until it is complete-
ly inserted.
For cars with alloy rims:
– Tighten the pin (A-fig. 9) in one of
the fastening bolt holes.
– Fit the wheel on the pin and fasten it
with four bolts.
– Remove the centering pin (A-fig. 9)
and tighten the last bolt.
– Lower the car and remove the jack; then
tighten the bolts as described previously for
the spare wheel (fig. 7).
WARNINGIncorrect fitting might cause
the wheel cap to come off when the car is
on the move.After refitting the wheel:
– stow the spare wheel in the space pro-
vided in the luggage compartment;
– insert the jack in its container forcing it
lightly to prevent it from vibrating during
travelling;
– place the tools used in the housings pro-
vided on the support;
– place the tool container on the spare
wheel and secure everything with the clamp-
ing device (A-fig. 2).fig. 8

INFLATING PROCEDURE 1)Place the wheel in the position illus-
trated in the figure (A-fig. 13) for the op-
eration with the valve, then engage the
handbrake.
2)Screw the filling pipe (B-fig. 14) to
the bottle (C).
3)Unscrew the tyre valve plug, remove
the element inside the valve by using the
appropriate tool (D-fig. 15); be careful
not to place it on the sand or on a dirty sur-
face .
4)Introduce the filling pipe (B-fig. 16)
in the tyre valve, keep the bottle (C-fig.
16) with the pipe directed downwards, then
press it so that the whole sealer can get in-
to the tyre.5)Screw again the element inside the
valve with the tool (D-fig. 17).
6)Use the appropriate lever (E-fig. 18)
to insert and clamp the air compressor pipe
(F) to the tyre valve.
7)Start the engine, insert the plug (G-
fig. 19) in the lighter (or socket 12V) and
inflate the tyre according to the right pres-
sure value (see “Cold inflation pressures” in
the “Technical specification” chapter). You
are advised to check the tyre pressure val-
ue on the pressure gauge (H-fig. 18) with
the compressor off, in order to have a more
accurate reading.fig. 13
