IN AN EMERGENCY

WARNING
129)Before replacing the bulb, wait for the
exhaust ducts to cool down: DANGER OF
SCALDING!
130)Modifications or repairs to the electric
system that are not carried out properly or
do not take the system technical
specifications into account can cause
malfunctions leading to the risk of fire.
131)Halogen bulbs contain pressurised gas,
in the case of breakage they may burst
causing glass fragments to be projected
outwards.
132)Only replace the light bulbs when the
engine is off and in a position that does not
interfere with traffic and lets you safely
replace them (see the description in the
“Replacement” paragraph). Also ensure that
the engine is cold, to prevent the risk of
burns.
IMPORTANT
55)Halogen bulbs must be handled holding
the metallic part only. Touching the
transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan of
the bulb. In the event of accidental contact,
wipe the bulb with a cloth moistened with
alcohol and let the bulb dry.

CHANGING A WHEEL
GENERAL INSTRUCTIONS
The car is equipped with the "Tire Repair
Kit": see the “Tire Repair Kit” paragraph
for how to use this device.
As an alternative to the “Tire Repair Kit”,
the car may be requested with a
space-saver wheel: see the instructions
on the following pages for changing the
wheel.
JACK
138) 139)
Please note that:
the jack weighs about 4.4 lb (2 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:
temperatures below −40°F (-40°C);
on sandy or muddy ground;
on uneven ground;
on steep slopes in extreme weather
conditions: thunderstorms, typhoons,hurricanes, blizzards, storms, etc.;
in direct contact with the engine or for
repairs under the car;
on boats.
CHANGING PROCEDURE
140) 141) 142) 143) 144) 145) 146)
58) 59)
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;
stop the engine, engage the hazard
warning lights and the parking brake;
engage P (Park) mode;
wear the reflective safety jacket
(compulsory by law) before getting out of
the car;
open the luggage compartment and lift
up the mat using the handle;
when the situation dictates it (for your
own safety and to comply with the
regulations in force in the country where
you are), take the warning triangle and
position it at a suitable distance from the
car;
unscrew the locking device 1 fig. 157,
take out the space-saver wheel and the
inflation compressor;
157

hose fitting 6 fig. 161;
make sure that the switch 8 on the
compressor 6 is in the 0 (off) position,
open the rear hatch and insert the plug
into the power socket in the luggage
compartment or on the central tunnel and
start the engine. Put the switch 8 in the I
(on) position;
inflate the space-saver wheel to a
pressure of 43.5 psi (3 bar);
IMPORTANT To conserve the battery
charge, it is recommended to leave the
vehicle running for the entire inflation
process.
To obtain a more accurate reading, it is
advisable to check the pressure of the
space-saver wheel on the pressure gauge
7 with the compressor off.
The compressor was designed
exclusively for inflating the space-saverwheel. Do not use it for inflating
mattresses, rafts, etc.
operate the extension lever 2 on the
jack 4 to lower the car;
then remove the jack 4;
use the wrench 3 to fully tighten the
bolts, passing alternately from one bolt
to the diagonally opposite one.
When replacing an alloy wheel, it is
advisable to place it upside down, with
the aesthetic part facing upwards.
WARNING
138)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.139)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.
140)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.

RUN FLAT TYRES
(where provided)
157) 158) 159)
"Run Flat" tyres allow you to maintain
control of the car after a puncture and to
continue driving safely for about 50 mi
(80 km) at a maximum speed of 50 mph
(80 km/h).
The reinforced tyre wall retains its shape
and supports the weight of the car in the
event of pressure loss.
Cars equipped with Run Flat tyres are
NOT provided with Tire Repair Kits. For
repair, contact an Alfa Romeo Dealership
as soon as possible.
WARNING
157)Do not exceed the maximum distance
or speed (80 km - 80 km/h) in the event of
pressure loss-puncture.
158)A pressure loss alters the driving
behaviour of the car, for example, causing
less directional stability when braking,
longer braking distances and altered
steering geometry. Therefore, adjust your
driving style to avoid sudden turns or
obstacles such as pavements and potholes.
159)Do not exceed 60 km/h when driving
with an especially heavy trailer.
JUMP STARTING
If the battery is flat, a jump starting can
be performed using the battery and the
cables of another vehicle, or using an
auxiliary battery. In all cases, the battery
used must have a capacity equal to or a
little higher than the flat one.
Jump starting may be dangerous if
carried out incorrectly: carefully follow
the procedures described below.
61)
IMPORTANT NOTES
Do not use an auxiliary battery or any
other source of external supply with a
voltage above 12 V: the battery, the
starter, the alternator and the electrical
system of the vehicle could be damaged.
Do not attempt jump starting if the
battery is frozen. The battery could break
and explode!
REMOTE BATTERY CONNECTION
POLES
To facilitate the operation, the remote
poles of the battery for the jump starting
can be found in the engine compartment:
the battery, on the other hand, is placed
in the luggage compartment.
The negative terminal (-) fig. 166 is
positioned next to the right bonnet lock.You can access the positive terminal (+)
by lifting the protective flap fig. 167.
The pole is shown in fig. 168.
16608076V0006EM
16708076V0002EM
163

To carry out the operation, you need to
have the correct cables to connect the
auxiliary battery to the remote poles of
the flat battery. Usually, these cables
have terminals at the ends and are
identified by different sheath colours
(red = positive, black = negative).
JUMP STARTING
160) 161) 162)
Proceed as follows:
switch off all electrical devices in the
car;
engage the parking brake, actiate P
(Park) mode and put the starter switch in
the STOP position;
should you be using the battery of
another car, park the other car within the
range of the cables used for the
connection, operate the parking brake
and ensure that its ignition is off.
IMPORTANT If the auxiliary battery is
installed on another vehicle, check that
there is no accidental contact of metal
parts between the two vehicles, since an
earth connection may result, with the risk
of serious injury to any people who may
be nearby.
IMPORTANT If the procedure below is
carried out incorrectly, it can cause
severe injury to people or damage the
recharging system of one or both
vehicles. Carefully follow the instructions
given below.
Cable connection
62)
Proceed as follows to carry out a jump
starting:
connect a terminal on the end of the
positive cable from the remote positive
pole (+) of the car with flat battery;
connect the terminal on the opposite
end of the positive (+) cable to the
positive (+) pole of the auxiliary battery;
connect a negative cable end terminal
to the negative (-) pole of the auxiliary
battery;
connect the terminal on the opposite
end of the negative (-) cable to the earth
point (-) on the car with the battery flat;
start the engine of the car with an
auxiliary battery, let it run for some
minutes at idle and then start the engineof the car with flat battery. In case a
portable battery is used, before starting
the car, wait a few seconds after
completing the connection.
Cable disconnection
Once the engine is started, remove the
connection cables in reverse sequence,
as shown below:
disconnect the negative cable end
terminal (-) from the earth point (-) of the
car with flat battery;
disconnect the terminal on the
opposite end of the negative cable from
the negative (-) pole of the auxiliary
battery;
disconnect the terminal on the
opposite end of the positive (+) cable
from the positive (+) pole of the auxiliary
battery;
disconnect the terminal on the end of
the positive cable from the remote
positive pole (+) of the car with flat
battery.
WARNING
160)Do not get too close to the radiator
cooling fan: the electric fan may start;
danger of injury. Scarves, ties and other
loose clothing might be pulled by moving
parts.

164
IN AN EMERGENCY

161)Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
162)The batteries contain acid that can
burn skin or eyes. Batteries produce
hydrogen, which is easily flammable and
explosive. Thus keep away flames or devices
which may cause sparks.
IMPORTANT
61)Never use a fast battery-charger to
start the engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and engine fuel
supply control units.
62)Do not connect the cable to the negative
terminal (–) of the flat battery. The following
spark could lead to battery explosion and
cause serious harm. Only use the specific
earth point; do not use any other exposed
metallic part.
FUEL CUT-OFFSYSTEM
DESCRIPTION
Depending on the type and violence of
the impact, the control unit of the ORC
occupant protection systems determines
whether to activate the airbags and the
front seat belt pretensioners and
whether to immediately interrupt the
current from the batteries to the supply
pumps and to the devices that operate
the engine. The power from the battery is
interrupted by "skipping" the pyrotechnic
fuse placed on the fusebox next to the
positive pole of the battery.
When the fuse is "skipped", only some
services, necessary for the safety of the
car (eg: door locks, anti-theft device, etc.),
remain powered.
IMPORTANT After the impact, carefully
check the car for fuel leaks, for instance
in the engine compartment, under the car
or near the tank area.
IMPORTANT Contact an Alfa Romeo
Dealership to have the system checked.
AUTOMATIC TRANSMISSION
GEAR LEVER UNLOCKING
To release the automatic transmission
lever, contact an Alfa Romeo Dealership.
165

take the tow hook from its housing in
the boot and carefully clean the threaded
housing on the vehicle before using it;
tighten the vehicle's tow hook in its
place for about 11 turns.
IMPORTANT The largest work angle of
the cable to fix on the tow hook must not
exceed 15°, as shown in fig. 171.
WARNING
163)Move the ignition device to ON and
then to STOP, without opening the door.
164)The brake servo and the
electromechanical power steering will not
work while the vehicle is being towed. You
will therefore need to apply more force on
the brake pedal and steering wheel. Do not
use flexible ropes when towing, and avoid
jerky movements. While towing, make sure
that the trailer hitch does not damage any
components it is touching. When towing the
car, you must comply with all specific traffic
regulations and adopt an appropriate
driving behaviour. Do not start the engine
while towing the vehicle. Before tightening
the ring, clean the threaded housing
thoroughly. Make sure that the ring is fully
screwed into the housing before towing the
car.
