CLOSINGProceed as follows:
❒hold the bonnet up with one hand and with the other remove rod C
fig. 69 from housing D and fit it back into its locking device;
❒lower the bonnet to about 20 cm from the engine compartment, then
let it fall and check, by trying to raise it, that it is completely closed
and not only attached in safety position. If it is not perfectly closed,
open the bonnet and repeat the procedure. Do not simply press it.
IMPORTANT Always check that the bonnet is closed correctly to avoid
it opening while the car is travelling.
For versions/markets where provided, the following plate is applied
inside the engine compartment fig. 70:
For safety reasons, the bonnet must always be
properly closed while driving. Make sure that the
bonnet is perfectly closed and that the lock is engaged.
If you discover during travel that the lock is not fully engaged,
stop immediately and close the bonnet in the correct manner.
Perform these operations only when the car is
stationary.The bonnet may drop suddenly if the supporting rod is
not positioned correctly.

EOBD SYSTEM (European On
Board Diagnosis)(for versions/markets, where provided)
The aim of the EOBD system (European On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace damaged components.
The car also has a diagnostic connector that can be interfaced with
appropriate tools, which makes it possible to read the error codes
stored in the electronic control units together with a series of specific
parameters for engine operation and diagnosis. This check can also be
carried out by the traffic police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.
ELECTRIC POWER STEERINGThis only operates with the key turned to MAR-ON and the engine
started. Power steering allows the force required at the steering wheel
to be adapted to driving conditions.
The different power assistance modes can be selected via the "d,n,a"
positions of the “Alfa DNA System” lever (see “Alfa DNA System”
paragraph).
It is absolutely forbidden to carry out any after-market
operation involving steering system or steering column
modifications (e.g.: installation of anti-theft device)
that could badly affect performance and safety, invalidate the
warranty and also result in non-compliance of the car with
type-approval requirements.Before performing any maintenance operations,
always turn off the engine and remove the key from
the ignition to lock the steering column, especially
when the car’s wheels are not touching the ground.

❒sensor performance can also be influenced by the position of the
sensors. For example by a change in the ride setting (caused by
the wear of the shock absorbers, suspension), overloading the
vehicle and carrying out specific tuning operations that require the
vehicle to be lowered;
❒The detection of obstacles at the top part of the car may not be
guaranteed because the system detects obstacles that could cause an
impact with the car in the bottom part.
TPMS (Tyre Pressure
Monitoring System)(for versions/markets, where provided)
The car may be fitted with a tyre pressure monitoring system (TPMS),
which informs the driver of the tyre inflation status via the "Check
tyre pressure" and "Low tyre pressure" messages on the display.
This system comprises a radio frequency transmitter fitted to each
wheel (on the wheel rim inside the tyre), which is able to send
information on the tyre inflation pressure of each wheel to the control
unit.IMPORTANT INFORMATION ABOUT
THE TPMSThe fault indications are not stored and will therefore not be displayed
after the engine has been switched off and then on again.
If the fault conditions persist, the control unit will send the relative
indications to the instrument panel only after the car has been in
motion for a short time.
The presence of the TPMS does not permit the driver to
neglect regular checks of the tyre pressure, including
for the spare wheel.Tyre pressure must be checked with tyres rested and
cold. Should it become necessary for whatever reason
to check pressure with warm tyres, do not reduce
pressure even though it is higher than the prescribed value, but
repeat the check when tyres are cold.

SAVING FUELHere are some suggestions which can help you to save fuel and lower
harmful emissions.GENERAL CONSIDERATIONSCar maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled Servicing Plan” (see chapter “Maintenance and care”).
Ty r e s
Check the tyre pressure at least once every 4 weeks: if the pressure is
too low, consumption levels increase as resistance to rolling is higher.
Unnecessary loads
Do not travel with an overloaded boot. The weight of the car and its
arrangement greatly affect fuel consumption and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack from the roof after use. These
accessories lower aerodynamic penetration and adversely affect
consumption levels. It is better to use a trailer to transport particularly
bulky objects.
Electrical devices
Only use electrical devices for the time needed. The heated rear
window, additional headlights, windscreen wipers and heater fan
require a considerable amount of energy; increasing the current uptake
increases fuel consumption (by up to +25% in an urban cycle).Climate control system
Using the climate control system will increase consumption: use the air
vents when the external temperature allows it.
Devices for aerodynamic control
The use of non-certified devices for aerodynamic control may adversely
affect air drag and fuel consumption.
DRIVING STYLEStarting
Do not warm up the engine at low or high revs when the vehicle is
stationary; this causes the engine to warm up more slowly, thereby
increasing fuel consumption and emissions. It is therefore advisable to
move off immediately, slowly, avoiding high speeds: in this way the
engine will warm up more quickly.
Unnecessary actions
Avoid revving up when at traffic lights or before switching off the
engine. The latter action, like double-declutching, is unnecessary and
causes increased fuel consumption and pollution.
Gear selection
Use a higher gear when traffic and road conditions allow it. Using a
low gear for faster acceleration will increase consumption. In the same
way improper use of a high gear increases consumption, emissions
and engine wear.

SNOW CHAINSThe use of snow chains should be in compliance with local regulations.
The snow chains may be applied only onto the front wheel tyres (drive
wheels).
Check the tension of the snow chains after the first few metres have
been driven.
Use reduced size snow chains: on all versions, for 195/55 R16" and
205/55 R16" size tyres use low-clearance snow chains with a
maximum projection beyond the tyre profile of 9 mm.
IMPORTANT The space-saver wheel cannot be fitted with snow chains.
If a front (drive) wheel is punctured and snow chains must be used,
you must remove a normal wheel from the rear and replace this one
with the space-saver wheel. In this way, with two normal drive wheels,
it is possible to use snow chains.
Keep your speed down when snow chains are fitted; do not
exceed 50 km/h. Avoid potholes, steps and pavements
and avoid driving long distances on roads not covered with
snow to avoid damaging the car and the roadbed.
STORING THE CARIf the car is to be left inactive for longer than a month, the following
precautions should be noted:
❒park the vehicle in a dry, covered and, if possible, ventilated area;
engage a gear and check that the handbrake is not engaged;
❒disconnect the negative battery terminal and check the battery
charge. Repeat this check once every three months during storage;
❒if you have not disconnected the battery, check the battery charge
every thirty days;
❒clean and protect the painted parts using protective wax;
❒clean and protect the shiny metal parts using special compounds
available commercially;
❒sprinkle talcum powder on the windscreen and rear window wiper
rubber blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perforated plastic sheet. Do not use
compact plastic sheets which do not allow humidity to evaporate
from the surface of the car.
❒inflate tyres to +0.5 bar above the standard specified pressure and
check it at intervals;
❒do not drain the engine cooling system.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the battery power supply.

The vehicle's driving characteristics will be modified
with the space-saver wheel fitted. Avoid violent
acceleration and braking, sharp steering and fast
cornering. The total life of a space-saver wheel is approximately
3,000 km, after which it must be replaced by another wheel of
the same type. Never attempt to fit a conventional tyre on a rim
designed for use as a space-saver wheel. Repair and refit the
standard wheel as soon as possible. Two or more space-saver
wheels should never be used together. Do not grease the threads
of bolts before fitting them: they might slip out.The jack provided is only intended to be used for
replacing tyres on the vehicle with which it is supplied,
or on same-model vehicles. Never use the jack for
other purposes, such as lifting other car models. Never use it for
repair operations under the vehicle. Incorrect positioning of the
jack may cause the car to fall. Do not use the jack for loads
higher than those shown on the label. Never install snow chains
on the small spare 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 small spare wheel on the
rear axle. In this way, with two normal front drive wheels, it is
possible to use snow chains.Incorrectly fitting the hubcap may cause it to fall off
when the vehicle is in motion. Never tamper with the
inflating 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").
JACKPlease 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 original one;
❒no tool other than its cranking device may be fitted on the jack.
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 1
agear or
reverse; put on the high visibility jacket (required by law) before
leaving the vehicle;
❒open the luggage compartment, pull tab A fig. 114 and lift up the
mat;

Never operate the compressor for longer than 20
consecutive minutes. Risk of overheating. The kit is not
suitable for definitive repairs, so the repaired tyres
may only be used temporarily.Dispose of the bottle and the sealant liquid properly. Have
the sealing fluid and the cylinder disposed of in compliance
with national and local regulations.The bottle contains ethylene glycol and latex: it may
cause an allergic reaction. It is harmful if swallowed. It
is irritant for the eyes in case of contact. There could
be a reaction in the event of inhalation or contact. Avoid contact
with the eyes, skin and clothes. In the event of contact, rinse
immediately with plenty of water. If ingested, do not induce
vomiting. Rinse out your mouth, drink large quantities of water
and seek immediate medical attention. Keep out of the reach
of children. The product must not be used by asthmatics. Do not
inhale the vapours during insertion and suction. Call a doctor
immediately if allergic reactions are noted. Store the bottle in the
specific compartment, away from sources of heat. The sealant
fluid has an expiry date. Replace the bottle containing out-of-
date sealant fluid.
INFLATION PROCEDURE
Wear the protective gloves provided with the kit.
Proceed as follows:
❒engage the handbrake, unscrew the tyre valve cap, take out the
flexible filler pipe A fig. 127 and tighten the ring nut B on the tyre
valve;
❒make sure that switch A fig. 128 for the compressor is in position 0
(off), start the engine, insert the plug A fig. 129 into the power
socket on the central tunnel and switch on the compressor by
bringing switch A fig. 128 to position I (on);
❒inflate the tyre to the pressure indicated in the “Wheels” paragraph
in the “Technical specifications” section. In order to obtain a more
precise reading, check the pressure value on pressure gauge B
fig. 128 with the compressor off;
❒if after five minutes it is still impossible to reach at least 1.8 bar,
disengage the compressor from the valve and power socket, then
move the car forwards by approx. ten metres in order to distribute
the sealing fluid inside the tyre evenly, then repeat the inflation
operation;

❒if you still cannot obtain a pressure of at least 1.8 bar within 5
minutes from the compressor switching on, do not drive off and
contact Alfa Romeo Authorized Services;❒after driving for about 10 minutes, stop and check the tyre pressure
again; remember to put the handbrake on;
❒if a pressure value of at least 1.8 bar is detected, restore the correct
pressure (with the engine running and the handbrake engaged),
resume driving and drive with great care to Alfa Romeo Authorized
Services.
Apply the adhesive label where it can be easily seen
by the driver as a reminder that the tyre has been
treated with the quick repair kit. Drive carefully,
particularly on bends. Do not exceed 80 km/h. Do not accelerate
or brake suddenly.If the pressure has fallen below 1.8 bar, do not drive
any further: the Fix&Go Automatic quick tyre repair kit
cannot guarantee the correct hold because the tyre is
too damaged. Contact Alfa Romeo Authorized Services.Inform the dealership that the tyre has been repaired
using the quick tyre repair kit. Give the leaflet to the
technicians who will be handling the tyre that was
repaired using the quick repair kit.
