engine overheat Alfa Romeo Giulia 2017 User Guide

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 systemcannotbe set:
When pressing the brake pedal.
When the brakes are overheated.
When the electric park 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 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
Plus system (if equipped) 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.
Changing Speed
Increasing speed
Once the system has been activated,
you can increase the speed by lifting
the SET switch. Each time it is
operated, the speed increases by
1 mph.
By holding the button up, the set speed
will increase in increments of five mph
until the button is released. Then, the
new speed will be set.
Decreasing speed
Once the system has been activated,
you can decrease the speed by
lowering the SET switch. Each time it is
operated, the speed decreases by
1 mph. By holding the button down, the set
speed will decrease in increments of
five mph until the button 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 Connect system
(see dedicated supplement).
When the unit of measurement is
set to metric, holding the SET switch
the speed will change 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 change 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.

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.
199

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 engine coolant
reservoir cap, wait for the system to
cool down. Topping Up / Draining / Flushing
The Engine 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 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 Engine Coolant
Disposal of engine coolant is subject to
legal requirements: contact the
appropriate body to determine local
regulations.
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.
218
SERVICING AND MAINTENANCE

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.

MMT In Gasoline
Methylcyclopentadienyl Manganese
Tricarbonyl (MMT) is a manganese-
containing metallic additive that is
blended into some gasoline to increase
octane. Gasoline blended with MMT
provides no performance advantage
beyond gasoline of the same octane
number without MMT. Gasoline blended
with MMT reduces spark plug life and
reduces emissions system performance
in some vehicles. The manufacturer
recommends that gasoline without
MMT be used in your vehicle. The MMT
content of gasoline may not be
indicated on the gasoline pump;
therefore, you should ask your gasoline
retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and
California reformulated gasoline.
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 your 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.
