INSTALLING A TOW HOOK
Contact an Alfa Romeo Dealership to
install a tow hook.
WARNING
105)The ABS with which the car is equipped
will not control the braking system of the
trailer. Particular caution is therefore
required on slippery roads.
106)Do not, under any circumstances,
modify the vehicle's braking system to
control the trailer breaking system. The
towing braking system must be completely
independent of the vehicle's hydraulic
system.
REFUELLING THE VEHICLE
During refuelling procedure, switch off
the engine, engage handbrake, rotate the
ignition key to STOP and do not smoke.
PETROL ENGINES
Only use unleaded petrol. The petrol
octane rating (RON) must not be lower
than 95. In order to prevent damage to
the catalytic converter never introduce
even the smallest amount of leaded
petrol, even in the event of an emergency.
DIESEL ENGINES
Only use diesel fuel compliant with
European specification EN590. The use
of other products or mixtures may
damage the engine beyond repair and
consequently invalidate the warranty,
due to the damage caused.
When using or parking the vehicle for a
long time in the mountains or cold areas,
it is advisable to refuel using locally
available Diesel. In this case, it is also
advisable to keep the tank over 50% full.
FUEL TANK CAP
107)
Opening
Open flap 1 fig. 76 pulling it outwards,
hold cap 2 still, insert the ignition key in
the lock and turn it anticlockwise. Then,turn the cap anticlockwise and remove it.
The cap has a loss prevention device
3 which secures it to the flap so that it
cannot be lost. Attach the cap to device
4 during refuelling.
Closing
Fit the cap (complete with key) and turn it
clockwise until it clicks once or more.
Then, turn the key clockwise and extract
it, then close the flap.
The sealing may cause a slight pressure
increase in the tank. A little breathing off,
while slackening the cap is absolutely
normal.
ENGINES WITH LPGSYSTEM
The gas filler is located next to the petrol
filler cap. It has a "non return", located in
the filler body itself.
To access the filler 2 fig. 77 open the
access flap 1.

CHANGING A WHEEL
JACK
117) 118) 119) 120) 121) 122)
30) 31)
Please note that:
the jack weight is 1.76 kg;
the jack requires no adjustment;
the jack cannot be repaired and in the
event of a fault it must be replaced by
another genuine one;
no tool other than its cranking device
may be fitted on the jack.
Jack maintenance
prevent any dirt from depositing on
the "worm screw";
keep the "worm screw" lubricated;
never modify the jack.
Conditions in which not to use the jack
temperature below -40°C
o sandy or muddy ground
on uneven ground
on steep roads
in extreme weather conditions:
thunderstorms, typhoons, hurricanes,
blizzards, storms, etc.
in direct contact with the engine or for
repairs under the vehicle
on boats.Wheel replacement procedure
To change a wheel, proceed as follows:
stop the car in a position that is not
dangerous for oncoming traffic where
you can change the wheel safely. The
ground must be flat and sufficiently
compact;
switch off the engine, pull up the
handbrake and engage the 1stgear or
reverse. Wear the reflective safety jacket
(compulsory by law) before getting out of
the vehicle;
open the luggage compartment, lift
the mat using the tab provided 1 fig. 96;
unscrew locking device 1 fig. 97, take
toolbox 2 and bring it next to the wheel to
replace. Then take the space-saver wheel
3;
for versions with steel rims: insert
the screwdriver in the opening 1 fig. 98 in
order to trigger the hub cap retaining clip
2;
for versions with alloy rims: shake the
car to facilitate detachment of the rim
from the wheel hub. Some versions may
be fitted with alloy wheels with a hub cap
fig. 99. To remove the hub cap, insert the
screwdriver into housings 1 in order to
access the fixing bolts. Replace the wheel
as described previously;

IN AN EMERGENCY

WARNING
117)The space-saver wheel is specific for
your car. Do not use it on cars of different
models. Do not use space-saver wheels of
different models on your car. The
space-saver wheel must only be used in the
event of an emergency. Never use it for more
than strictly necessary and never exceed
80 km/h. On the space-saver wheel there is
an orange label, summarising the main
warnings regarding space-saver wheel
usage restrictions. Never remove or cover
the label. Never apply any hub cap to the
space-saver wheel.118)Alert other drivers that the car is
stationary in compliance with local
regulations: hazard warning lights, warning
triangle, etc. Any passengers on board
should leave the car, especially if it is heavily
laden. Passengers should stay away from
on-coming traffic while the wheel is being
changed. On hills or uneven roads, use
chocks or appropriate objects to block the
wheels of the vehicle.
119)The vehicle's driving characteristics
will be modified with the space-saver wheel
fitted. Avoid violent acceleration and
braking, abrupt steering and fast cornering.
The overall duration of the space-saver
wheel is about 3000 km, after which the
relevant tyre must be replaced with another
one of the same type. Never install a
traditional tyre on a rim designed to be used
as a space-saver wheel. Have the wheel
repaired and refitted as soon as possible.
Using two or more space-saver wheels at the
same time is forbidden. Do not apply grease
to the bolt threads before fitting: they could
come unscrewed.
120)The jack may be used to replace
wheels only on the car that it comes with or
other cars of the same model. Never use the
jack for other purposes, such as lifting other
vehicle models. Never use it for repair
operations under the vehicle. Incorrect
positioning of the jack may cause the vehicle
to fall. Do not use the jack for loads higher
than the one shown on its label. Never install
snow chains on the space-saver wheel; if a
front tyre (driving wheel) is punctured and
you need to use snow chains, use a standard
wheel from the rear axle and install the
space-saver wheel on the rear axle. In this
way, with two normal front drive wheels, it is
possible to use snow chains.121)Incorrectly fitting the wheel cap may
cause it to fall off when the car is in motion.
Never tamper with the inflation valve. Never
introduce tools of any kind between rim and
tyre. Regularly check the inflation pressure
of the tyres and space-saver wheel (see
chapter "Technical specifications").
122)The jack is a tool developed and
designed only for changing a wheel, if a tyre
gets punctured or damaged, on the vehicle
with which it is supplied or on other vehicles
of the same model. Any other use, e.g. to jack
up other vehicle models or different things,
is strictly prohibited. Never use for
maintenance or repair activities under the
car or to exchange the summer/winter
wheels and vice versa. Never go under the
raised vehicle. Should it be necessary to
work under the vehicle, contact an Alfa
Romeo Dealership. Incorrect positioning of
the jack may cause the raised vehicle to fall:
use only in the positions indicated. Do not
use the jack for loads higher than the one
shown on its label. Never start the engine
with vehicle raised. If the vehicle is raised
more than necessary, everything can
become more unstable, with the risk of the
vehicle dropping violently. Thus, lift the
vehicle only as needed in order to access the
spare wheel.

if after five minutes pressure is not at
least 1.8 bar/26 psi, turn off the
compressor and disconnect it from the
valve and power socket, replace the cap,
then move the vehicle forwards by
approx. ten metres in order to distribute
the sealing fluid inside the tyre evenly.
Stop the vehicle safely and repeat the
operation above until the required
pressure is reached;
if after this operation you still cannot
reach at least 1.8 bar/26 psi after
5 minutes from switching on the
compressor, THE TYRE IS TOO
DAMAGED TO BE REPAIRED. Remove
and place the kit in the specific
compartment and contact an Alfa Romeo
Dealership;
if the required pressure is reached,
restart driving. Do not exceed 80 km/h.
Avoid sudden acceleration or braking.
After driving for about 8 km / 5 miles,
place the vehicle in a safe and suitable
area, engaging the parking brake. Pick up
the kit, ensure the on-off button is in0
position, insert the electrical connector in
the vehicle 12V socket. Remove the cap
from the valve of repaired tyre,
disconnect and pull out the black inflation
tube, connect it to the valve and lock it
with the lever. Check the tyre pressure on
the pressure gauge.
if the pressure is lower than 1.8 bar /
26 psi, the TYRE IS TOO DAMAGED AND
CANNOT BE REPAIRED. Remove and
place the kit in the specific compartment
and contact an Alfa Romeo Dealership;
if the pressure indicated is equal to or
higher than 1.8 bar/26 psi, switch on the
compressor and inflate to the required
pressure. Disconnect and replace the kit
in the specific compartment. Drive
carefully to the nearest Alfa Romeo
Dealership as soon as possible.
CHECKING AND RESTORING TYRE
PRESSURE
The compressor can also be used to
check and, if necessary, restore the tyre
pressure.
Disconnect and pull out the black
inflation tube 1 fig. 110, connect and to
the tyre valve and lock in position with
the lever.
With the same procedure it is possible to
inflate bicycle tyres and balloons. The kit
should be used by adults and cannot be
used by children.

which can be purchased at an Alfa Romeo
Dealership.
To remove the cartridge, disengage the
coupling of the black inflation tube,
rotate the cartridge anticlockwise and
then lift it. Insert the new cartridge,
rotate it clockwise to its end of travel,
insert the coupling of the black inflation
tube blocking it with the lever and then
rewind the transparent tube into its
compartment on the compressor.
IMPORTANT
32)Show the package and the label to the
personnel charged with handling the tyre
treated with the tyre repair kit.33)Fix&Go provides a temporary repair,
therefore the tyre must be examined and
repaired by a specialist as soon as possible.
The sealing fluid is effective at temperatures
between -40°C and +50°C. It is possible to
repair tyres which have been damaged on
tread up to a diameter of 4mm; however,
tyres damaged on their side cannot be
repaired. Before using Fix&Go kit, ensure
that the tyre isn't excessively damaged and
that the rim is in good condition, otherwise
do not use it and contact an Alfa Romeo
Dealership. Do not remove foreign bodies
from the tyre. Do not let the compressor
turned on for more than 20 consecutive
minutes - overheating hazard.
WARNING
123)The information required by the
applicable regulation is indicated on the
Fix&Go kit package label. Compliance with
the indications on the label is an essential
condition to ensure the safety and the
effectiveness of the Fix&Go kit. Carefully
