is not dangerous for the traffic where it is
possible to change the wheel safely.
Where possible, park on a level, compact
surface.
– Engage the handbrake
– Engage 1st gear or reverse. For cars
with automatic gearbox set the lever to
positionP.
– Open the boot.
– Fold back the boot mat (A-fig. 1).– Take the tool bag (A-fig. 3) and
the spare wheel and bring them near to
the wheel to be changed.

– 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).

– Put jack and tools back in the bag
and stow it in the boot
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.

fig. 23 IMPORTANTThe headlight inner sur-
face might be slightly misted: this should
not be considered irregular but a natural
phenomenon due to low temperature and
the air humidity level. Misting will disap-
pear as soon as the headlights are turned
on. Drops inside the headlight mean wa-
ter infiltration: contact Alfa Romeo Autho-
rized Services.

Halogen bulbs must be
handled touching only
the metallic part. If the
transparent bulb is touched with
the fingers its lighting intensity
is reduced and the life of the bulb
may be compromised. If touched
accidentally, rub the bulb with a
cloth moistened with methylated
spirits and allow to dry.
Where possible the
bulbs should be re-
placed by Alfa Romeo
Authorized Services. The correct
operation and positioning of the
external lights are vital to the
safety of the vehicle and its pas-
sengers and the subject of specif-
ic laws.
Halogen bulbs contain
pressurised gas, in the
case of breakage they may burst.
WARNING

FRONT LIGHT UNITS - GAS
DISCHARGE HEADLIGHTS
(optional for versions/markets where
applicable)
The front light units with gas discharge
headlights contain low beam/high beam
(gas discharge), high beam headlamp
signaller (halogen), sidelight and direc-
tion indicator bulbs.
The bulbs are arranged inside the light
unit as follows (fig. 24-25):
A.Direction indicator
B.High beam headlamp signaller and
sidelight
C.Gas discharge low beam/high beam.Low beams/high beams
Xenon bulbs are very longlasting and
failure is highly unlikely.
The following paragraph describes how
to replace xenon bulbs correctly.
Any work on the front
light units should be car-
ried out with the light switch at
position 0 (lights off) and with the
ignition key removed from the
switch: danger of electric dis-
charge.
