engine Alfa Romeo Giulia 2019 Workshop Manual

IMPORTANT It is dangerous to leave the
device activated when it is not used.
There is a risk of inadvertently activating
it and losing control of the vehicle due to
unexpected excessive speed.
Pausing / Deactivating
With the device enabled (speed not set),
press the
button.
With the device activated (speed set),
press the
button to enter the Paused
state. The display shows the white icon
with the speed in brackets. Press the
button again to deactivate the device
completely.
SETTING THE DESIRED SPEED
The speed can be set from a minimum of
30 km/h (or 20 mph for markets with
instrument panels in mph) to a maximum
of 180 km/h (or 110 mph for markets
with instrument panels in mph).
When the car reaches the desired speed,
raise/lower the SET fig. 105 switch and
release it to activate the device. When
the accelerator is released, the vehicle
will keep the selected speed
automaticallyWhile the accelerator pedal is pressed:
the device will not be able to control
the distance between the vehicle and the
one ahead. In this case the speed will be
determined only by the position of the
accelerator pedal.
The device will return to normal
operation as soon as the accelerator
pedal is released.
The systemcannotbe set:
when pressing the brake pedal;
when the brakes are overheated;
when the electric parking brake has
been operated;
when either P (park), R (reverse) or N
(neutral) is engaged;
when the engine rpm is above a
maximum threshold;
when the vehicle speed is not within
the settable speed range;
when the ESC (or ABS or other
stability control systems) are operatingor have just operated;
when the ESC system is off;
when the Forward Collision Warning
Plus system (where provided) is braking
automatically;
in the event of device failure;
when the engine is off;
in case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
In case of system set, the conditions
described above also cause a
cancellation or deactivation of the
system with times that may vary
according to the conditions.
IMPORTANT The device will not be
deactivated when speeds higher than
those set are reached by pressing the
accelerator pedal (180 km/h or 110 mph,
the latter for instrument panels set to
miles per hour). In these conditions, the
device may not work correctly and it is
advisable to deactivate it.
CHANGING SPEED
Speed increase
Once the device has been activated, you
can increase the speed by lifting the SET
switch. Each time it is operated, the
speed increases by 1 mph (1 km/h).
By holding the button up, the set speed
will increase in steps of 6 mph (10 km/h)
10507146S0017EM
123

until the button is released, then the new
speed will be stored.
Decreasing speed
Once the device has been activated, you
can decrease the speed by lowering the
SET switch. Each time it is operated, the
speed decreases by 1 mph (1 km/h).
By holding the button down, the set
speed will decrease in steps of 6 mph
(10 km/h) until the button is released,
then the new speed will be stored.
IMPORTANT Moving the SET switch
allows you to adjust the speed according
to the selected unit of measurement
("metric" or "imperial") set on the
Connect system (see dedicated
supplement).
Important notes
By keeping the accelerator pedal
depressed, the car can continue to
accelerate beyond the set speed. In this
case, use the SET switch to set the speed
to the vehicle’s current speed.
When the SET button is pressed to
reduce the speed, the braking system
intervenes automatically if the engine
brake does not slow the car down
sufficiently to reach the set speed. The
device holds the set speed uphill and
downhill; however a slight variation is
entirely normal, particularly on slight
gradients.The automatic transmission could change
to a lower gears when driving downhill or
when accelerating. This is normal and
necessary to maintain the set speed.
The device is switched off while driving if
the brakes overheat.
ACCELERATING WHEN OVERTAKING
When driving with the device active and
following a vehicle, the device provides
additional acceleration to facilitate
overtaking, when travelling over a given
speed and switches on the left direction
indicator (of the right indicator for
right-hand drive versions).
In left-hand traffic, the overtaking assist
function is only active when the left-hand
lane is used for overtaking the vehicle
ahead (the opposite activation logic is
used in right-hand traffic countries).
The device detects the direction of
traffic automatically when the vehicle
passes from left-hand traffic to
right-hand traffic. In this case, the
overtaking assist function is only active
when the reference vehicle is overtaken
on the right. The additional acceleration
is activated when the driver uses the
right direction indicator.
In this condition, the device no longer
provides the overtaking assist function
on the left-hand side until it determinesthat the vehicle has returned to left-hand
traffic conditions.
RECALLING THE SPEED
Once the system has been cancelled but
not deactivated, if a speed was
previously set simply press the RES
button and remove your foot from the
accelerator to recall it.
The system will be set to the last stored
speed.
Before returning to the previously set
speed, bring the speed close to that
value, then press the RES button and
release it.
IMPORTANT The recall function must
only be used if the road and traffic
conditions so allow. Recalling an
excessively high or low speed for the
current traffic and road conditions could
cause an acceleration or a deceleration

STARTING AND DRIVING

LANE DEPARTURE WARNING
(LDW) SYSTEM
DESCRIPTION
51) 52) 53) 54) 55) 56)
The Lane Departure Warning system
makes use of a camera located on the
windscreen to detect the lane limits and
calculate the position of the vehicle
within such limits, in order to make sure
that it remains inside the lane.
When one or both lane limits are
detected and the vehicle passes over one
without the driver's say-so (direction
indicator not turned on), the system
emits an acoustic signal.
If the vehicle continues to go beyond the
line of the lane without any intervention
from the driver, the surpassed line will
light up on the display (left or right) to
urge the driver to bring the vehicle back
into the limits of the lane.
SYSTEM ON/OFF
The system is activated/deactivated by
pressing the button fig. 112
Each time the engine is started, the
system maintains the operating mode
that was selected when it was previously
switched off.Activation conditions
Once switched on, the system becomes
active only if the following conditions are
met:
the car speed is higher than 37 mph
(the system is deactivated at speeds
equal to or higher than 110 mph –
180 km/h);
the lane limit lines are visible at least
on one side;
there are suitable visibility conditions;
the road is straight or with wide radius
bends;
a suitable distance is kept from the
vehicle in front;
the direction indicator (for leaving the
lane) is not active.
IMPORTANT
51)Projecting loads on the roof of the
vehicle may interfere with the correct
operation of the camera. Before starting
make sure the load is correctly positioned, in
order not to cover the camera operating
range.
52)If the windscreen must be replaced due
to scratches, chipping or breakage, contact
exclusively an Alfa Romeo Dealership. Do not
replace the windscreen on your own, risk of
malfunction! It is advisable to replace the
windscreen if it is damaged in the area of the
camera.
53)Do not tamper with nor operate on the
camera. Do not close the openings in the
aesthetic cover located under the interior
rear view mirror. In the event of a failure of
the camera, contact an Alfa Romeo
Dealership.
54)Do not cover the operating range of the
camera with stickers or other objects. Also
pay attention to other objects on the bonnet
(e.g. a layer of snow) and make sure they do
not interfere with the camera
55)The camera may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow,
formation of ice layers on the windscreen.

STARTING AND DRIVING

The table below shows the approximate
distances for each area fig. 114:
AreaDistance from the
rear part of the car
Red 0-1ft(0–30cm)
Y
ellow 1 - 3.3 ft (30 cm-1m)
Green 3.3 ft (1 m) or more
IMPORTANT When parking, take the
utmost care over obstacles that may be
above or under the camera range.
WARNING
124)Parking and other potentially
dangerous manoeuvres are, however,
always the driver’s responsibility. While
carrying out these manoeuvres, always
make sure that no people (especially
children) or animals are in the area
concerned. The camera is an aid for the
driver, but the driver must never allow
his/her attention to lapse during potentially
dangerous manoeuvres, even those
executed at low speeds. Always keep a slow
speed, so as to promptly brake in the case of
obstacles.
IMPORTANT
57)It is vital, for correct operation, that the
camera is always kept clean and free from
any mud, dirt, snow or ice. Be careful not to
scratch or damage the camera while cleaning
it. Avoid using dry, rough or hard cloths. The
camera must be washed using clean water,
with the addition of car shampoo if
necessary. In washing stations which use
steam or high-pressure jets, clean the
camera quickly, keeping the nozzle more
than 10 cm away from the sensors. Also, do
not apply stickers to the camera.
REFUELLING THE VEHICLE
125) 126) 127)
Always stop the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol with a number
of octanes (R.O.N.) not lower than 91
(EN228 specification).
DIESEL ENGINES
Only use automotive diesel fuel
(EN590 and EN16734 specifications).
Operation at low temperatures
If the outside temperature is very low,
Diesel thickens due to the formation of
paraffin clots with consequent defective
operation of the fuel supply system.
In order to avoid these problems,
different types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold,
mountain areas).
In the event of refuelling with diesel
which is unsuitable for the operating
temperature, it is advisable to mix the
diesel with a specific additive,
introducing it to the tank before the
anti-freeze and then the diesel.

128)
Preliminary conditions
Proceed as follows:
park the car on level ground;
switch off the engine by turning the
ignition device to STOP;
open the fuel flap 1 fig. 115, then undo
and remove the cap 4 (blue) from the
AdBlue® filler and place it in the specific
housing (the same one used for housing
the fuel cap 2, see fig. 115 ).
Refilling with nozzles
You can fill up at any AdBlue® distributor.
Proceed as follows:
insert the AdBlue® nozzle in the filler,
start refilling and stop refilling at the first
shut-off (the shut-off indicates that the
AdBlue® tank is full). Do not proceed with
the refilling, to prevent spillage of
AdBlue®;
extract the nozzle.
Refilling with containers
Proceed as follows:
check the expiration date;
read the advice for use on the label
before pouring the content of the bottle
into the AdBlue® tank;
if systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
11507226S0041EM

11707206S0002EM
133

indication appears on the instrument
panel display (see “Warning lights and
messages" paragraph in the “Knowing the
instrument panel” chapter), fill the
AdBlue® tank with at least 1.11 UK gal –
5 litres;
if containers which can be screwed to
the filler are used, the reservoir is full
when the AdBlue® level in the container
stops pouring out. Do not proceed
further.
Operations after refilling
Proceed as follows:
fit the cap 4 fig. 115 back on the
AdBlue®filler by turning it clockwise and
screwing it completely;
set the ignition device to ON (it is not
necessary to start the engine);
wait for the indication on the
instrument panel to switch off before
moving the car. The indication may stay
on for a few seconds to approximately
half a minute. If the engine is started and
the car is moved, the indication will
remain on for longer. This will not
compromise engine operation;
if the AdBlue® was topped up when the
tank was empty, see the “Refuelling ”
paragraph in the “Technical
Specifications” chapter and wait for
2 minutes before starting the engine.
IMPORTANT If AdBlue® is spilled out of
the filler neck, clean up well the area andproceed to filling up again. If the liquid
crystallises, eliminate it with a sponge
and warm water.
IMPORTANT
If AdBlue® is spilled on painted
surfaces or aluminium, immediately
clean the area with water and use
absorbent material to collect the fluid
that has been spilled on the ground.
Do not try to start the engine if
AdBlue® was accidentally added to the
Diesel fuel tank, this can result in
serious engine damage, contact an Alfa
Romeo Dealership.
Do not add additives or other fluids
to AdBlue®, doing so could damage the
system.
The use of non-conforming or
degraded AdBlue® may lead to
indications appearing on the
instrument panel display (see “Warning
lights and messages" paragraph in the
“Knowing the instrument panel”
chapter).
Never pour AdBlue® into another
container: it could be contaminated.
In case of damage to the sewage
system of exhaust gas resulting from
the use of additives / tap water, the
introduction of diesel fuel, or at least
by not fulfilling the requirements, the
warranty expires.
If the AdBlue® runs out, see “Warning
lights and messages" paragraph in the
“Knowing the instrument panel”
chapter to continue using the car
normally.
The AdBlue® level is not updated if
the car is parked on a sloping road.

STARTING AND DRIVING

128)If the AdBlue overheats for a
prolonged period inside the tank to over 50
°C (for example, due to direct solar
irradiation), the AdBlue may decompose and
produce ammonia vapours. Ammonia
vapours have a pungent odour when the cap
of the AdBlue tank is unscrewed, therefore
be careful not to inhale any ammonia
vapours in the tank outlet. In this
concentration, however, the ammonia
vapors are not harmful or dangerous to
health.AdBlue® (UREA) ADDITIVE FOR
DIESEL EMISSIONS
(2.2 JTD versions only)
The car is equipped with an UREA
injection system and Selective Catalytic
Reduction to meet emission standards.
These two systems ensure compliance
with the diesel emissions requirements;
at the same time, they ensure
fuel-efficiency, handling, torque and
power. For messages and system
warnings, refer to the "Warning lights and
messages" paragraph in the "Knowing the
instrument panel" chapter.
AdBlue® (UREA) is considered a very
stable product with a long shelf life.
Stored at temperatures LOWER than
89.6° F (32 °C), it has a shelf life of at
least one year.
For more information on the AdBlue®
liquid type, see the “Fluids and lubricants”
paragraph in the “Technical
specifications” chapter.
The car is provided with an automatic
AdBlue® heating system when the engine
starts allowing the system to work
correctly at temperatures lower than
-11 °C.
IMPORTANT AdBlue® freezes at
temperatures lower than 12.2 °F (-11 °C).
SUGGESTIONS FOR DRIVING
SAVING FUEL
Below are some suggestions which may
help you save fuel and thus lower the
amount of harmful emissions released
into the atmosphere.
Vehicle maintenance
Checks and operations should be carried
out in accordance with the "Scheduled
Servicing Plan" (see chapter
"Maintenance and care").
Tyres
Check the tyre pressures at least once
every four 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 vehicle and its
arrangement greatly affect fuel
consumption and stability.
Electric devices
Use electrical devices only for the
amount of time needed. The heated rear
window, additional headlights, screen
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).
136
STARTING AND DRIVING

Climate control system
Using the climate control system will
increase consumption: use standard
ventilation when the temperature
outside permits.
Devices for aerodynamic control
The use of non-certified devices for
aerodynamic control may adversely
affect air drag and consumption levels.
DRIVING STYLE
Starting
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 starting at traffic
lights or before stopping the engine. The
latter action, as well as double-
declutching, is unnecessary and causes
increased fuel consumption and
pollution.Gear selection
Use a high gear when traffic and road
conditions allow it. Using a low gear for
faster acceleration will increase fuel
consumption. In the same way, improper
use of a high gear increases consumption,
emissions and engine wear.
Max. speed
Fuel consumption considerably increases
as speed increases. Maintain a constant
speed, avoiding unnecessary braking and
acceleration, which cost in terms of both
fuel consumption and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions: acceleration
should be gradual and should not exceed
the maximum torque.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach optimum
operating temperature. This results in a
significant increase in consumption
levels (from +15 to +30% on the urban
cycle) and emissions.
Traffic and road conditions
High fuel consumption is caused by heavy
traffic, for instance when travelling in a
queue with frequent use of low gears or
in cities with many traffic lights. Winding
mountain roads and rough road surfaces
also adversely affect consumption.
Stops in traffic
During prolonged hold-ups (e.g. level
crossings) switch off the engine.
