engine Alfa Romeo Giulia 2016 Workshop Manual

FUEL CUT-OFFSYSTEM
DESCRIPTION
139)
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 seatbelt 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 fuse box next to the
positive pole of the battery.
When the fuse is "skipped", only some
services, necessary for the safety of the
vehicle (eg: door locks, anti-theft device,
etc.), remain powered.
IMPORTANT After the impact, carefully
check the vehicle for fuel leaks, for
instance in the engine compartment,
under the vehicle or near the tank area.
IMPORTANT Contact an Alfa Romeo
Dealership to have the system checked.
WARNING
139)If, after an impact, you smell fuel or
notice leaks from the fuel system, do not
reactivate the system to avoid the risk of
fire.
137

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. 147.
WARNING
140)Move the ignition device to ON and
then to STOP, without opening the door.
141)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. During 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 car. Before tightening the
ring, clean the threaded housing thoroughly.
Make sure that the ring is fully screwed into
the housing before towing the car.

SCHEDULED SERVICING
Correct servicing is crucial for
guaranteeing a long life for the vehicle
under the best conditions.
For this reason, Alfa Romeo has planned
a series of checks and services at fixed
distance intervals and, for
versions/markets, where provided, at
fixed time intervals, as described in the
Scheduled Servicing Plan.
Before each service, it is always
necessary to carefully follow the
instructions in the Scheduled Servicing
Plan (e.g. periodically check level of
fluids, tyre pressure, etc.).
Scheduled Servicing is offered by an Alfa
Romeo Dealership according to a set
time schedule. If, during each operation,
in addition to the ones scheduled, the
need arises for further replacements or
repairs, these may be carried out with the
owner's explicit consent only.
IMPORTANT Scheduled Servicing
Coupons are required by the
Manufacturer. Failure to have them
carried out may invalidate the warranty.
It is advisable to inform the Alfa Romeo
Dealership of any small operating
irregularities without waiting for the next
service.
PERIODIC CHECKS
Every year or every600mi (1,000 km) or
before long trips check and, if necessary,
top up:
engine coolant level;
brake fluid level (if insufficient, see an
Alfa Romeo dealership as soon as
possible);
windscreen washer fluid level;
tyre inflation pressure and condition;
operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.);
operation of screen washing/wiping
system and positioning/wear of wiper
blades.
Every1,800mi (3,000 km), check and
top up if required: engine oil level.
HEAVY USAGE OF THE CAR
If the vehicle is used under one of the
following conditions:
dusty roads;
short, repeated journeys (less than
4-5 mi (7-8 km)) at sub-zero outside
temperatures;
engine often idling or driving long
distances at low speeds or long periods
of inactivity;
in the event of a long period of
inactivity;
the following checks must be carried outmore often than indicated in the
Scheduled Servicing Plan:
check front and rear disc brake pad
condition and wear;
check cleanliness of bonnet and boot
locks, cleanliness and lubrication of
linkage;
visually inspect conditions of: engine,
gearbox, transmission, pipes and hoses
(exhaust/fuel system/brakes) and rubber
elements (gaiters/sleeves/bushes, etc.);
check battery charge and battery fluid
level (electrolyte);
visually inspect conditions of the
accessory drive belts;
check and, if necessary, change engine
oil and replace oil filter;
check and, if necessary, replace pollen
filter;
check and, if necessary, replace air
cleaner;
check and, if necessary, replace the
Bad Fuel fuel filter (where available).

Engine oil consumption
57)
4)
The maximum engine oil consumption is
usually 0.55 pounds (250 grams) every
620 mi (1,000 km). When the vehicle is
new, the engine needs to be run in;
therefore the engine oil consumption can
only be considered stabilised after the
first 3,100 - 3,730 mi (5,000 -
6,000 km).
ENGINE COOLANT FLUID
145)
58)
If the level is too low, unscrew the cap of
reservoir 2 and add the fluid described in
the "Technical Specifications" chapter.
WASHER FLUID FOR WINDSCREEN/
HEADLIGHTS
146) 147)
The windscreen and headlights washer
fluid reservoir (where available) is
equipped with a telescopic filler.
If the level is too low, remove reservoir
cap 4 and lift the filler then add the fluid
described in the "Technical
Specifications" chapter.
IMPORTANT The headlight washing
system will not work if the liquid level is
low (situation indicated by the symbol on
the instrument panel display). The
windscreen washer will keep working. On
vehicles equipped with headlight
washers, Where provided, there is a
reference notch on the dipstick: ONLY
the windscreen/rear window washer
operates with the level below this
reference.
BRAKE FLUID
Check that the fluid is at the max. level. If
the liquid level in the tank is insufficient,
contact an Alfa Romeo Dealership to
have the system checked.

USEFUL ADVICE FOR EXTENDING THE
LIFE OF YOUR BATTERY
Useful advice for extending the life of
your battery
To avoid draining your battery and make
it last longer, observe the following
instructions:
when you park the car, ensure that the
doors, tailgate and bonnet are closed
properly, to prevent any lights from
remaining on inside the passenger's
compartment;
switch off all roof lights inside the car:
the car is however equipped with a
system which switches all internal lights
off automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before performing any operation on
the electrical system, disconnect the
negative battery cable.
If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
147

influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to indicate
this. To carry out this procedure, simply
turn the steering wheel all the way from
one end to the other and then put it back
to the central position.
IMPORTANT If the charge level remains
under 50% for a long time, the battery is
damaged by sulphation, reducing its
capacity and efficiency at start-up. The
battery is also more prone to the risk of
freezing (at temperatures as high as 14
°F (-10°C)).BATTERY
148) 149) 150) 151)
59)
6)
The battery does not require the
electrolyte to be topped up with distilled
water. A periodic check carried out at an
Alfa Romeo Dealership is, however,
necessary to check efficiency.
Follow the battery manufacturer's
instructions for maintenance.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to indicate
this. To carry out this procedure, simply
turn the steering wheel all the way from
one end to the other and place it back in
central position.
IMPORTANT If the charge level remains
under 50% for a long time, the battery is
damaged by sulphation, reducing its
capacity and efficiency at start-up. The
battery is also more prone to the risk of
freezing (at temperatures as high as 14
°F (-10°C)).
WARNING
142)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
143)Be very careful when working in the
engine compartment when the engine is hot:
you may get burned. 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.
144)If the engine oil is being topped up, wait
for the engine to cool down before loosening
the filler cap, particularly for vehicles with
aluminium cap (where provided). WARNING:
risk of burns!
145)The cooling system is pressurised. If
necessary, only replace the plug with
another original or the operation of the
system may be adversely affected. Do not
remove the reservoir plug when the engine is
hot: you risk scalding yourself.
146)Do not travel with the windscreen
washer fluid reservoir empty: the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
147)Some commercial additives for
windscreen washer fluid are flammable. The
engine compartment contains hot
components which may start a fire.
148)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
148
SERVICING AND CARE

149)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
150)If the vehicle must remain unused for a
long time at a very low temperature, remove
the battery and take it to a warm place, to
avoid freezing.
151)When performing any operation on the
battery or near it, always protect your eyes
with special goggles.
IMPORTANT
55)Be careful not to confuse the various
types of fluids while topping up: they are not
compatible with each other! Topping up with
an unsuitable fluid could severely damage
your vehicle.
56)The oil level must never exceed the MAX
reference.
57)Do not add oil with specifications other
than those of the oil already in the engine.
58)Use a fluid of the same type as that
already present in the reservoir for any
topping up of the engine cooling system. The
fluid cannot be mixed with other types of
antifreeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
an Alfa Romeo Dealership.
59)When you need to disconnect or remove
the battery, do not close the boot. In order to
avoid possible accidental closure, it is
recommended to place an obstacle (e.g. a
cloth) on the lock that would physically avoid
closure.
IMPORTANT
4)Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters, we
advise you to contact an Alfa Romeo
Dealership.
5)Used transmission fluid contains
substances that are harmful to the
environment. You are advised to contact an
Alfa Romeo Dealership for oil changes.
6)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an Alfa Romeo
Dealership.
BATTERY RECHARGING
IMPORTANT NOTES
152) 153)
IMPORTANT Before using the charging
device, always make sure that it is
appropriate for the installed battery,
with constant voltage (below 14.8 V) and
low amperage (maximum 15 A).
IMPORTANT Recharge the battery in a
well ventilated environment.
IMPORTANT Never charge or recharge a
frozen battery: it may explode because
of the nitrogen trapped inside the ice
crystals.
IMPORTANT At all times while charging
or recharging the battery, make sure that
any sparks or open flames are kept
sufficiently far away from the battery.
IMPORTANT Before using any devices to
charge or to maintain the charge of the
battery, carefully follow the instructions
provided with the device in order to
