2018 Alfa Romeo Giulietta engine

Move the stalk upwards (unstable
position) to limit operation to the time
for which the stalk is held in this position.
When released, the stalk will return to its
default position and the windscreen
wiper will be automatically stopped.
“Smart washing” function
Pull the stalk towards the steering wheel
(unstable position) to operate the
windscreen washer. Keep the stalk pulled
for more than half a second to operate
the windscreen washer jet and wiper
automatically with a single movement.
The windscreen wiper stops working
three strokes after the stalk is released.
A further stroke after approx. 6 seconds
completes the wiping cycle.
RAIN SENSOR
(for versions/markets, where provided)
It can detect the presence of rain and
consequently manage windscreen wiping
in accordance with the amount of water
on the windscreen.
The sensor is activated when the ring 2
fig. 22 is turned to "automatic" position
("AUTO" control): the windscreen wiper
stroke frequency is thus adjusted in
accordance with the amount of water on
the windscreen.
If no rain is detected, the wiper will not
carry out any strokes.If the engine is switched off with the
lever in the automatic position, when the
car is next started, no wiping cycle will
take place even if it is raining. This is to
prevent unwanted activation of the rain
sensor when the engine is started (i.e.
when the windscreen is being washed by
hand or the wiper blades are stuck to the
windscreen by ice).
To restore automatic operation of the
rain sensor, turn the ring on the right stalk
2 fig. 22 from automatic position (AUTO)
to positionOand then turn ring 2 back to
the AUTO position.
When the rain sensor is reactivated using
any of the manoeuvres described above,
reactivation is indicated by a single
stroke of the windscreen wipers,
regardless of the condition of the
windscreen.
REAR WINDOW WIPER/WASHER
(for versions/markets, where provided)
This operates only with the ignition key
turned to MAR.
Turn ring 1 fig. 22 from positionOto
position
to operate the rear window
wiper as follows:
in intermittent mode when the
windscreen wiper is not operating;
in synchronous mode (at half the
speed of the windscreen wiper) when the
windscreen wiper is operating;
in continuous mode with reverse gear
engaged and the control active.
Pushing the stalk towards the dashboard
(rocking position) will activate the rear
window washer jet. Keep the stalk pushed
for more than half a second to activate
the rear window wiper as well. Releasing
the stalk will activate the smart washing
function, as described for the windscreen
wiper.
IMPORTANT
5)Never use the windscreen wipers to
remove layers of snow or ice from the
windscreen. In such conditions, the
windscreen wiper may be subjected to
excessive stress and the motor cut-out
switch, which prevents operation for a few
seconds, may intervene. If operation is not
restored (even after restarting that car with
the key), contact an Alfa Romeo Dealership.
6)Do not operate the windscreen wiper with
the blades lifted from the windscreen.

Air distribution selection
Air flow to the windscreen and front side window vents to demist/defrost them.
Air flow at central and side dashboard vents to ventilate the chest and the face during the hot season.
Air flow to the front and rear footwell vents. This air distribution setting heats the passenger compartment most quickly, giving
a prompt sensation of warmth
IMPORTANT In warm-humid weather conditions, using cold air on the windscreen may cause external condensation.
In AUTO mode, the climate control system automatically manages air distribution (the LEDs on buttons H are off). When set
manually, the air distribution is indicated by the LEDs on the selected buttons switching on.
You can also set a combination of the air distribution settings described above. In combined function mode the relevant function is
enabled simultaneously with those already set by pressing the corresponding button. If a button whose function is already active is
pressed, the operation is cancelled and the corresponding LED switches off. To restore automatic control of the air distribution after
a manual selection, press the AUTO button.
Start&Stop
The automatic dual zone climate control system manages the Start&Stop system (engine off when car speed is 0 km/h) to ensure
adequate comfort inside the car. When the Start&Stop system is on (engine off and car at a standstill), the automatic recirculation
management is turned off always taking air in from outside, to reduce the probability of the windows misting up (as the compressor
is off).
IMPORTANT
2)The system uses a coolant that is compatible with the laws in force in the countries where the vehicle is sold, R134a or R1234yf (indicated on a
specific plate in the engine compartment). The use of other coolants affects the efficiency and condition of the system. Also the compressor
coolants used must be compatible with the indicated coolant.

HEADLIGHTS
LIGHT BEAM DIRECTION
The correct orientation of the headlights
is important for the driver's comfort and
safety as well as for all other road users.
This is also covered by a specific rule of
the highway code.
The headlights must be correctly
directed to ensure the best visibility
conditions for all drivers. Contact a Alfa
Romeo Dealership to have the headlights
checked and adjusted, if necessary.
FOG LIGHTS ALIGNMENT(for versions/markets, where provided)
Contact a Alfa Romeo Dealership to have
the headlights checked and adjusted, if
necessary.
ADJUSTING THE HEADLIGHTS ABROAD
The dipped beam headlights are aligned
to comply with the regulations of the
country of purchase. When driving in
countries with a different traffic
direction, to avoid blinding the drivers
travelling in the opposite direction, it is
necessary to cover the areas of the beam
according to the provisions of the
Highway Code of the country you are
driving in.
Alfa DNASYSTEM (Car dynamic
control system)
This device allows, using lever 1
fig. 33 (on the central tunnel), three car
response modes to be selected according
to driving style and road conditions:
d=Dynamic(sports driving mode);
n=Natural(mode for driving in normal
conditions);
a=All Weather(mode for driving in
poor grip conditions, such as rain and
snow).
The lever 1 is of the monostable type. In
other words, it always remains in a
central position.
The selected driving mode is indicated by
the corresponding LED switching on in
the panel and by an indication on the
reconfigurable multifunction display.When “Natural” mode is selected, no
messages or symbols are shown on the
display.
The device acts on the dynamic car
control systems (engine, steering, ESC,
ASR, ELECTRONIC Q2 systems, etc.).
TURNING “Dynamic” MODE ON/OFF
9)
IMPORTANT For versions/markets,
where provided, switching to "Dynamic"
mode is automatically disabled in the
first kilometres in order to guarantee
correct settling of the mechanical
components. If an attempt to activate
the system is made before this limit, the
display will show a dedicated message to
remind the driver that this request
cannot be fulfilled.
Activation
Move lever 1 fig. 33 downwards (to the
letter “d”) and hold in this position for
0.5 seconds until the corresponding LED
lights up or the word “Dynamic” appears
on the display.
When lever 1 fig. 33 is moved to the “d”
position, the activation of “Dynamic”
mode is confirmed by a temporary
variation in the brightness (flashing) of
the instrument panel.

LPG/PETROL SWITCH
20)
15)
This engine normally runs on LPG except
during starting when it runs on petrol.
Switching to LPG takes place
automatically and is indicated by the
switching-off of icon
on the display,
next to the letters LPG.
To switch to the other fuel type, press the
button
with the car stationary and
engine on, or while driving.
If the LPG runs out during LPG operation,
the system automatically switches over
to running on petrol.
The four bars near the letters LPG in the
display indicate the level of LPG in the
tank.
REFUELLING
LPG
Maximum refuelling capacity (including
reserve): 38 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required for
priming; this figure represents the
maximum permitted capacity. In addition,
after different refuelling processes, this
figure may vary due to differences
between the network pump supply
pressures, pumps having differentsupply/locking features, tank not
completely run out of fuel.
IMPORTANT In order to avoid
inconsistent information by the LPG
gauge on the instrument panel, it is
recommended to refill with at least
10 litres each time.
WARNING
19)Note that in some countries (including
Italy) there are legal restrictions in force for
parking/garaging motor vehicles fuelled by
gas that is denser than air; LPG comes under
this category.
20)Do not switch between the two
operating modes whilst starting the engine.
21)If gas is smelt, switch from LPG
operation to petrol operation and
immediately go to an Alfa Romeo Dealership
to have the vehicle checked and possible
system faults excluded.
IMPORTANT
10)The car is equipped with a specifically
designed gaseous LPG injection system: it is
therefore absolutely forbidden to alter the
configuration of the system or its
components. The use of other components or
materials could cause malfunctions and lead
to a reduction in safety; therefore, in the
case of problems, contact an Alfa Romeo
Dealership. When towing or lifting the
vehicle, follow the instructions in the main
handbook under the paragraph on "Towing
the vehicle" to prevent damage to the gas
system parts.
11)The system operates at temperatures
ranging between -20°C and 100°C.
12)When using a painting oven, the LPG
tank should be removed from the car and
later carefully refitted at an Alfa Romeo
Dealership. Although the LPG system has
numerous safety features, it is advisable to
proceed as follows every time the vehicle is
not in use for a long period or moved in an
emergency as a result of a breakdown or
accident: unscrew the devices fastening the
cover of the LPG tank, then remove it. Close
the LPG cock rotating the ring nut clockwise
(see "Passive safety / active safety"). Refit
the cover and retighten the fastening
devices.
34
GETTING TO KNOW YOUR CAR

13)Only use LPG for motor vehicles.
14)It is strictly forbidden to use any additive
in the LPG. Periodically (at least once every
six months) it is advisable to let the LPG in
the tank run out and, at the first refuelling, to
check that it does not exceed the maximum
capacity of 38 litres (reserve included) (with
a tolerance of 2 litres excess). If the level is
above 38 litres (reserve included) contact an
Alfa Romeo Dealership immediately.
15)When switching is requested, metallic
noise from the valves which pressurise the
circuit can be heard. For the switching logic
described above, a delay between the valve
ticking and the switching off of the
instrument panel indication is completely
normal.
16)In particular usage conditions, such as
starting and operation at low ambient
temperature or LPG supply with low propane
content, the system may switch temporarily
to petrol operation, without a visual
indication of switching on the instrument
panel. In the event of low LPG levels in the
tank or request for high performance (e.g.
overtaking, car fully laden, steep hills) the
system may automatically switch to petrol
operation to guarantee the engine power
requested; the green warning light on the
instrument panel switches on to indicate this.
When the above conditions are no longer
present, the system automatically restores
LPG operation; the green warning light
switches off. To achieve the automatic
switching described above, make sure that
there is always enough fuel in the petrol tank.
