2018 Alfa Romeo Giulia engine overheat

When the system is enabled and ready to
operate, the display shows the white icon
above dashes in place of the speed.
Setting a speed activates the system.
The display shows the icon in green with
the set speed.
Note:The system cannot be enabled
when RACE mode is active.
Warning!
Leaving the Adaptive Cruise Control (ACC)
system on when not in use is dangerous. You
could accidentally set the system or cause it
to go faster than you want. You could lose
control and have a collision. Always leave
the system off when you are not using it.
Pausing/Deactivating
With the feature enabled (speed not set),
push the
button to disable.
With the feature active (speed set), push
the
button to pause. The display will
show the icon in white with the speed in
brackets. To deactivate the feature, push
the
button a second time.
Setting The Desired Speed
The speed can be set from a minimum of
20 mph (30 km/h) to a maximum of
110 mph (180 km/h).
When the vehicle reaches the desired
speed, push the SET switch upward or
downward and release it to activate the
system. When the accelerator is released,
the vehicle will maintain the set speed
automatically. While the accelerator pedal is pressed,
the system 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 system will return to normal
operation as soon as the accelerator
pedal is released.
The system
cannotbe set:
When pressing the brake pedal.
When the brakes are overheated.
When the electric park brake has been
operated.
When either PARK (P), REVERSE (R) or
NEUTRAL (N) is engaged.
When the engine rpm is above a
maximum threshold.
When the vehicle speed is not within
the operational speed range.

When the ESC (or ABS or other
stability control systems) are operating
or have just operated.
When the ESC system is off.
When the Forward Collision Warning
system is braking automatically.
In the event of system 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).
If the system is set, the conditions
described above also cause a
cancellation or deactivation of the
system. These situations may vary
according to the conditions.
Note: The system will not be deactivated
when speeds higher than those set are
reached by pressing the accelerator
pedal above 110 mph (180 km/h). In
these situations, the system may not
work correctly and it is recommended to
deactivate it.
To Vary The Speed Setting
Increasing Speed
Once the system has been activated, you
can increase the speed by pushing the
SET switch upward. Each time the switch
is pushed, the speed increases by 1 mph. By pushing and holding the switch
upward, the set speed will increase in
increments of 5 mph until the switch is
released. Then, the new speed will be set.
Decreasing Speed
Once the system has been activated, you
can decrease the speed by pushing the
SET switch downward. Each time the
switch is pushed, the speed decreases
by 1 mph.
By pushing and holding the switch
downward, the set speed will decrease in
increments of 5 mph until the switch is
released. Then, the new speed will be set.
Note:
Moving the SET switch allows you to
adjust the speed according to the
selected unit of measurement ("US" or
"Metric") set on the Information and
Entertainment System (see dedicated
supplement).
When the unit of measurement is set
to Metric, pushing and holding the SET
switch will adjust the speed in 10 km/h
increments.
By keeping the accelerator pedal
depressed, the vehicle 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 you push the SET button to
reduce the speed, the braking system
intervenes automatically if the engine
brake does not slow the vehicle 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
inclines.
The transmission could shift to a
lower gear when driving downhill, or
when accelerating. This is normal and
necessary to maintain the set speed
The system will disable while driving
if the brakes overheat.
Accelerating When Overtaking
When driving with ACC activated and
following a vehicle, the system will
provide an additional acceleration up to
the ACC set speed to assist in passing the
vehicle. This additional acceleration is
triggered when the driver utilizes the left
turn signal and will only be active when
passing on the left hand side.
The system 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 deactivated when the driver uses the
right direction indicator and returns to
the original lane.

ENGINE OVERHEATING
Engine overheating may occur in
situations of extreme environmental
temperatures, frequent engine
stops/starts, or driving in heavy traffic.
If the engine becomes overheated, the
Engine Temperature Warning Light in the
instrument cluster will illuminate along
with a dedicated message. Refer to
"Warning Lights And Messages" in the
"Getting To Know Your Instrument Panel"
for more information.
In any of the following situations, you can
reduce the potential for overheating by
taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place
the transmission in NEUTRAL, but do not
increase engine idle speed.
Note: There are steps that you can take
to slow down an impending overheat
condition:
If your air conditioner (A/C) is on, turn
it off. The A/C system adds heat to the
engine cooling system and turning the
A/C off can help remove this heat.
You can also turn the temperature
control to maximum heat, the mode
control to floor and the blower control to
high. This allows the heater core to act
as a supplement to the radiator and aids
in removing heat from the engine cooling
system.
Warning!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never try to open a cooling system pressure
cap when the radiator or coolant bottle is
hot.
Caution!
Driving with a hot cooling system could
damage your vehicle. If temperature gauge
reads “H”, pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned
off until the pointer drops back into the
normal range. If the pointer remains on the
“H”, turn the engine off immediately, and call
for service.
If Steam Is Coming From The Engine
Compartment
Do not go near the front of the vehicle.
Stop the engine. Wait until the steam
dissipates. Then, open the hood and start
the engine.
If Neither Coolant Nor Steam Is
Escaping
Open the hood and idle the engine until it
cools.
Note:
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and contact your authorized
dealer.
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Contact your authorized dealer.
189

Coolant Check
Your vehicle has two cooling systems and
they both need to be checked to ensure
they are at proper fill levels. Refer to the
“Engine Compartment” section for the
locations.
Check the engine coolant and intercooler
coolant level every oil change or before
long trips.
If there are impurities in the engine
coolant, the system must be drained,
flushed and refilled: contact an
authorized dealer.
Check the front part of the condenser to
check for any build-up of insects, leaves
or other debris. Should it be dirty, clean it
by spraying delicately with water.
Check the hoses of the engine/
intercooler cooling system to ensure that
the rubber has not deteriorated and that
there are no cracks, tears, cuts or
obstructions in the expansion tank side
and radiator side connectors. Should
there be any doubt regarding leaks from
the system (e.g. if frequent top ups are
required), have the seal checked at an
authorized dealer.
With the engine off and at normal
operating temperature, check that the
cooling system radiator cap is closed
properly.
Warning!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure cap while
the system is hot or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Note: Before removing the coolant
reservoir cap, wait for the system to cool
down.
Topping Up / Draining / Flushing The
Engine/Intercooler Coolant
If the engine coolant (antifreeze) is dirty,
have cleaning and flushing carried out at
an authorized dealer.
See the "Maintenance Plan" for the
correct servicing intervals.
Note:
For topping up, use a fluid with the
same characteristics as those indicated
in the "Fluids And Lubricants" table (see
"Technical Specifications" chapter).
Do not use pure water, alcohol-based
coolants, corrosions inhibitors or
additional anti-rust products because they may be incompatible with the
engine coolant and cause the clogging of
the radiator. The use of propylene
glycol-based coolant is also not
recommended.
Engine Cooling/Intercooler System Cap
To prevent loss of engine coolant, make
sure that the expansion tank cap is
closed. If it is open, screw it completely
until you reach/hear the click.
Periodically check the cap and clean it
from any foreign bodies that may have
deposited on the external surface.
Warning!
Never add coolant with the engine hot or
overheated.
Do not attempt to cool an overheated
engine by loosening or removing the cap.
The heat causes a considerable increase in
pressure in the cooling system.
To prevent damage to the engine, only use
the engine cooling circuit caps provided.
Disposal Of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements: contact
the appropriate body to determine local
regulations.
206
SERVICING AND MAINTENANCE

Note:
To prevent the fluid from being
ingested by children or animals, do not
keep it in open containers or pour it on
the ground. If ingested, contact a doctor
immediately. Eliminate any traces of
fluid from the ground immediately.
When the vehicle stops after a short
trip, steam may be seen coming out from
front of the hood. This is a normal
phenomenon which is due to the
presence of rain, snow or a lot of
moisture on the surface of the radiator.
With engine and system cold, do not
top up with coolant beyond the
maximum level indicated on the
reservoir in the engine compartment.
Braking System
In order to guarantee the efficiency of
the braking system, periodically check its
components; for this operation, contact
an authorized dealer.
See the "Maintenance Plan" for the
correct servicing intervals.
Note: Driving with your foot resting on
the brake pedal may compromise its
efficiency, increasing the risk of
accidents. When driving, never keep your
foot on the brake pedal and don’t put
unnecessary strain on it to prevent the brakes from overheating: excess pad
wear may cause damage to the braking
system.
When an insufficient oil level is
detected, contact an authorized dealer
to have the system checked.
Always keep the cap of the brake
fluid reservoir (in the engine
compartment) completely closed.
Warning!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information. Using the wrong type of brake
fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder
reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake fluid
or fluid that has been in a tightly closed
container. Keep the master cylinder
reservoir cap secured at all times. Brake
fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly
during hard or prolonged braking, resulting
in sudden brake failure. This could result in a
collision.
Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot engine
parts, causing the brake fluid to catch fire.
Brake fluid can also damage painted and
vinyl surfaces, care should be taken to avoid
its contact with these surfaces.
Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This could
result in a collision.
Automatic Transmission
Use only a transmission oil with the same
characteristics as those indicated in the
"Fluids and Lubricants" table (see
"Technical Specifications" chapter).
Special Additives
Do not use any type of additive with the
automatic transmission oil. The
automatic transmission oil is a product
designed specially for this vehicle and its
performance may be compromised
through the use of further additives.
Caution!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such
damage is not covered by the New Vehicle
Limited Warranty.
207

Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that
contain detergents, corrosion and
stability additives are recommended.
Using gasolines that have these additives
will help improve fuel economy, reduce
emissions, and maintain vehicle
performance.Designated TOP TIER
Detergent Gasoline
contains a higher level
of detergents to
further aide in
minimizing engine and
fuel system deposits.
When available, the usage of TOP TIER
Detergent gasoline is recommended.
Visit www.toptiergas.com for a list of
TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system
cleaning agents should be avoided. Many
of these materials intended for gum and
varnish removal may contain active
solvents or similar ingredients. These can
harm fuel system gasket and diaphragm
materials.
Fuel System Cautions
Caution!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited
by Federal law. Using leaded gasoline can
impair engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the
catalytic converter to overheat. If you
notice a pungent burning odor or some light
smoke, your engine may be out of tune or
malfunctioning and may require immediate
service. Contact an authorized dealer for
service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle
performance problems resulting from the
use of such fuels or additives is not the
responsibility of the manufacturer and may
void or not be covered under the New
Vehicle Limited Warranty.
Note: Intentional tampering with the
emissions control system can result in
civil penalties being assessed against
you.
