2019 Alfa Romeo Giulia engine

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.

IN AN EMERGENCY

EMERGENCY 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.
63)
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. 144 fig. 8 is
positioned next to the right bonnet lock.The positive pole (+) can be accessed by
removing the cover fig. 145
open protective flap fig. 146.The pole is shown in fig. 147.
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).
