– Tighten the five fastening bolts (A-
fig. 12).– Lower the car and remove the jack
(fig. 13).– Completely tighten the bolts in the se-
quence shown (fig. 14).
– On cars having the same alloy rims
as the spare wheel ones, wheel cap can
be fitted following the instructions given
in the following paragraph.
IMPORTANTNever fit the wheel cap
to the spare wheel if the spare wheel is
different from the standard one.
After refitting a wheel:
– Stow the spare wheel in the space
provided in the luggage compartment and
fasten it with the ring nut (A-fig. 2).
– Put jack and tools back in the bag and
stow it in the boot.

– Work the jack and raise the car, until
the wheel is a few centimetres above
ground.
– Completely unscrew the fastening
bolts (A-fig. 16) and remove the
wheel.
– Make sure that the wheel to be in-
stalled is clean and free of impurities on
the hub contact surface which could cause
slackening of the fastening bolts later.
– Install the wheel making the hub pin
(A-fig. 10) coincide with one of the
holes (B-fig. 11) of the wheel.
– Tighten the five fastening bolts (A-
fig. 17).
For cars with alloy rims it is easier to in-
sert the wheel bolts using the specific
centering pin.– Screw the centering pin (A-fig. 18)
in one of the fastening bolt holes.
– Push the wheel on the pin and fasten
it with four bolts.
– Remove the centering pin (A-fig. 19)
and screw the last fastening bolt.– Lower the car and remove the jack
(fig. 20).
– Completely tighten the bolts in the se-
quence shown (fig. 21).
– If present, fit the hub cap so that the
valve can come out through the tapered
hole. Press the edges of the hub cap s-
tarting from near the valve hole (A-
fig. 22) and proceeding round until it is
securely attached.
IMPORTANT Incorrect fitting might
cause the wheel cap to come off when
the car is on the move.
After refitting a wheel:
– Stow the spare wheel in the space
provided in the luggage compartment and
fasten it with the ring nut (A-fig. 2).

Do not grease the threads
of bolts before installing
them; they might slip out.
The bolts should be tightened to a
torque of 86 Nm (8.8 kgm).
You are advised to have the wheel
bolt tightening checked by Alfa
Romeo Authorized Services as
soon as possible.
Indeed, insufficient tightening may
cause the wheel bolts to slacken
with the obvious dangerous con-
sequences. Excessive tightening
can strain the bolts.

housed in the right and left lower part of
the underbody.
Towing another vehicle
(fig. 98-99)
The tow ring supplied with the vehicle is
housed in the tool container under the
boot mat.To install the tow ring, proceed as fol-
lows:
– Take the tow ring from the tool con-
tainer.
– Remove the cover (A-fig. 98) s-
nap-fitted on the rear bumper as follows:
Take the screwdriver from the tool con-
tainer in the boot, under the trim.Using the flat bladed side protected with
a soft cloth, insert the screwdriver on the
upper part of the cap and press gently to
prise the catch from its housing.
– Firmly screw the ring (B-fig. 99) in
its housing.

IS TO BE LIFTED
USING THE JACK
See paragraph “In the event of a punc-
ture” of this chapter.
You are informed that.
– the jack mass is 2.100 kg;
– the jack requires no adjustment;
– the jack cannot be repaired and in
case of breakage it must be replaced by
another original one.
– no tool other than its cranking lever
may be installed on the jack.
Before beginning to tow
the car, turn the ignition
key to MAR and then to STOP, do
not remove it. Removing the key
automatically engages the steering
lock resulting in the impossibility
to steer the wheels. When towing
remember that without the help of
the servobrake and power steer-
ing, it is necessary to exert more
effort on the brake pedal and for
steering. Do not use flexible cables
for towing and avoid jerks. During
towing operations make sure that
fastening the joint to the car does
not damage the components in
contact with it. When towing the
car it is compulsory to comply with
the specific traffic regulations con-
cerning both the towing device and
behaviour on the road.
WARNING
The car may fall if the
jack is not positioned cor-
rectly. Never use the jack for
higher capacities than the one
stated on its label.
The purpose of the jack is
only for replacing wheels
on the car with which it is provided
or on cars of the same model. It
must never be used for other pur-
poses such as for example raising
cars of other models. In no case
must it be used for repairs under
the car.
WARNING
WARNING

203
It is possible to ask the Alfa Romeo Or-
ganisation for an estimate of the cost of
service coupon operations.
IMPORTANTYou are advised to con-
tact Alfa Romeo Authorized Services in
the event of any minor operating faults,
without waiting for the next service cou-
pon.
IMPORTANTThe programmed main-
tenance coupons are specified by the
Manufacturer. The failure to have them
carried out may invalidate the warranty.GENERALITIES
Perfect performance and the life of eve-
ry car are strictly connected with correct
use of it, but above all on the care with
which routine maintenance operations are
carried out for which new programming
criteria have been adopted owing to prod-
uct development.
The mileage for programmed mainte-
nance coupons is 20,000 km.
It is however wise to remember that the
car still needs routine care such as for in-
stance checking and topping up the
fluids, checking the tyre pressure, etc.
Correct vehicle maintenance is surely
the best way to preserve its performance
levels, safety and environment protection
features and low running costs over the
years.
Also remember that strictly observing
the maintenance instructions given in this
Handbook marked by the symbol
—can be a necessary condition for the guar-
antee. If the car is frequently
used for towing trailers,
the interval between
programmed maintenance opera-
tions should be reduced.
Warning, when topping
up never confuse the
various types of fluids
which are incompatible and could
seriously damage the vehicle.

IMPORTANT - Engine oil
Change the engine oil more frequently
than stated in the Scheduled Mainte-
nance Programme if the car is used pre-
vailingly in one of the following particular-
ly harsh conditions:
– trailer or caravan towing
– dusty roads
– short, repeated journeys (less than 7-
8 km) with an outside temperature of be-
low freezing point.
– engine idling frequently or driving
long distances at low speed (e.g. taxi or
door-to-door deliveries) or in the case of
prolonged inactivity.
IMPORTANT - Air cleaner
Using the car on dusty roads, change
the air cleaner more frequently than stat-
ed in the Scheduled Maintenance Pro-
gramme.
For any doubts about the intervals be-
tween engine oil and air cleaner changes
in relation to how the car is used, contact
Authorised Alfa Romeo Services.IMPORTANT - Fuel oil filter
The variety of the degree of purity of
the fuel oil in commerce may make it
necessary to change the fuel oil filter
more frequently than stated in the Sched-
uled Maintenance Programme. If the en-
gine is “sobbing” it is a sign that the fil-
ter needs changing.
IMPORTANT - Pollen filter
If the car is used frequently in dusty or
heavily polluted environments, you are
recommended to change the activated
carbon filtering element more frequently;
in particular, it should be changed if a
lower flow of air admitted to the passen-
ger compartment is noted.IMPORTANT - Batteries
You are recommended to have the bat-
tery charge conditions checked, prefer-
ably at the onset of winter, to avoid the
possibility of freezing the electrolyte.
This check should be carried out more
frequently if the car is used prevailingly
for short journeys, or if it is fitted with
services that absorb high amounts of cur-
rent permanently with the ignition key
off, especially if installed in the after mar-
ket.
In the case of use of the car in hot cli-
mates or particularly harsh conditions, it
is wise to check the level of the battery
fluid (electrolyte) at more frequent inter-
vals than stated in the Scheduled Mainte-
nance Programme.
IMPORTANT - Remote control
If when pressing the remote control but-
ton of the key, the operating led on the
key flashes briefly only once, the battery
need replacing with other of the same
type.
