coolant Alfa Romeo Giulia 2017 Owner's Manual

The engagement of the recirculation
system makes it possible to reach the
required heating or cooling conditions
faster. It is, however, inadvisable to use
it on rainy/cold days as it can increase
the possibility of the windows fogging.
When the outside temperature is low,
recirculation is forced off to prevent the
windows from fogging up.
A/C Compressor
Push the A/C buttonto activate or
deactivate the A/C compressor
(indicator illuminated when activated).
The A/C compressor will remain off
even after the engine has stopped.
When the A/C compressor is turned off,
the system deactivates air recirculation
to prevent the windows from fogging
up. If the climate control system can
maintain the temperature, with the A/C
turned off, the AUTO feature will remain
on and the AUTO button indicator light
will not switch off.
To restore automatic control of the A/C
compressor, push the A/C button
or
the AUTO button. With the A/C
compressor off, the air speed can be
set manually using the Air Speed
Adjustment Knob.
When the A/C compressor is on, and
the engine is running, air speed cannot
be lower than the minimum speed (only
one indicator light is lit). Note:
When the A/C is off the Climate
Control system can not produce air that
is colder than the current outside
temperature. Under certain
environmental conditions, windows
could fog up rapidly, since the air is not
dehumidified.
Front Defroster And
MAX-DEF Function
Push the Front Defroster button(indicator illuminated) to defrost the
windshield and side windows.
While in MAX-DEF function, the air
conditioner will:
Activate the air conditioner
compressor when the weather allows
Turn air recirculation off
Set the maximum air temperature (HI)
on both the driver and passenger side
Activate a blower speed based on
the temperature of the engine coolant
Adjust the air flow towards the
windshield and front side windows
Activate the Rear Window Defroster
Display the fan speed (indicators
illuminated) and current air distribution
setting
Note: The MAX-DEF function remains
active for approximately three minutes
once the engine coolant reaches the
proper temperature. When the function is on, AUTO mode
will deactivate. The only manual
operations possible are adjusting
blower speed and turning off the Rear
Window Defroster.
Pushing the
button switches off the
MAX-DEF function.
Rear Defroster
Push the Rear Defrosterbutton to
activate (indicators illuminated) the Rear
Defroster.
The Rear Defroster will turn off after
20 minutes or once the engine is turned
off. To reactive the Rear Defroster, push
the Rear Defroster
button.
Note: To avoid damage, do not apply
stickers over the interior heating
filaments of the Rear Defroster.
Humidity Sensor
The Humidity Sensor helps to prevent
the windows from fogging up. The
AUTO function (indicator illuminated)
must be on for the Humidity Sensor to
function.
When outside temperature is low, the
system may turn the compressor on
and turn air recirculation off for safer
driving.

Switching Off/On The
Climate Control System
Switching Off The Climate Control
System
Rotate the Air Seed Adjustment Knob
completely to the left to turn off the
Climate Control System.
With the air conditioner off:
Air recirculation is on.
The A/C compressor is off.
Thefanisoff.
The heated rear window can be
activated/deactivated.
Note:
The climate control system stores the
previously set temperatures and
resumes operation when any button on
the system is pushed.
Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start Evo
The climate control system manages
the Stop/Start Evo system. Stop/Start
Evo has the engine shut off when
vehicle speed is 0 mph (0 km/h) to
maintain comfort within the vehicle.
Stop/Start Evo will deactivate in the
following scenarios:
The climate control system is in
AUTO mode (indicator illuminated), and
the vehicle has yet to reach the set
temperature
The LO setting is active
MAX-DEF status is active
When the Stop/Start Evo system is
active, the engine will restart if the
inside temperature changes
significantly, or if the LO setting, or
MAX-DEF setting, is activated.
With Stop/Start Evo system on, air flow
is reduced to keep the compartment
comfort conditions for longer.
Until the temperature drastically
changes within the cabin, the climate
control system will continue to maintain
the temperature while the engine is off.
By deactivating the Stop/Start Evo
system with the
button located on
the dashboard, the climate control
system will take priority over the engine
shutting off. Note:
In harsh climate conditions, limit the
use of the Stop/Start Evo system to
prevent the compressor from
continuously switching on and off. This
will cause rapid misting of the windows
and the accumulation of humidity in
the passenger compartment.
When the Stop/Start Evo system is
on, the climate control system will
always take air in from outside,
reducing the probability of the windows
fogging up.
Additional Heater — If
Equipped
Note:
The additional heater automatically
operates if the outside temperature and
engine coolant temperature are low.
The heater will not operate if battery
voltage is low.
System Maintenance
In winter, the Climate Control System
must be turned on at least once a
month for approximately 10 minutes.
Have the system inspected at an
authorized dealer before the summer.

GETTING TO KNOW YOUR VEHICLE

Caution!
If the LOW ENGINE OIL PRESSURE symbol switches on when driving, stop the engine immediately and contact an authorized dealer.
SymbolWhat It Means What To Do
ENGINE TEMPERATURE WARNING LIGHT
This light warns of an overheated engine condition. If
the engine coolant temperature is too high, this
indicator will illuminate and a single chime will sound. If
the temperature reaches the upper limit, a continuous
chime will be sound for 4 minutes or until the engine is
allowed to cool whichever comes first.In normal driving conditions
: stop the car, switch off the
engine and check that the coolant level in the reservoir
is not below the MIN mark. In this case, wait for the
engine to cool down, then slowly and carefully open the
cap, top up with coolant and check that the level is
between the MIN and MAX marks on the reservoir itself.
Also check visually for any fluid leaks. Contact an
authorized dealer if the symbol comes on when the
engine is started again.
If the vehicle is used under demanding conditions (e.g.
in high-performance driving): slow down and, if the
warning light stays on, stop the vehicle. Stop for two or
three minutes with the engine running and slightly
accelerated to facilitate better coolant circulation, then
turn the engine off. Check that the coolant level is
correct as described above.
POWER STEERING FAILURE
If the symbol remains on, you could not have steering
assistance and the effort required to operate the
steering wheel could be increased; steering is, however,
possible. Contact an authorized dealer as soon as possible.

Warning!
If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
SymbolWhat It Means What To Do
INSUFFICIENT ENGINE COOLANT LEVEL (if equipped)
If the symbol switches on, it indicates a low engine
coolant level condition.Top up, as described in the "Servicing And
Maintenance" chapter
ACTIVE CRUISE CONTROL SYSTEM FAILURE
While driving, if the warning light switches on, it signals
a failure in the Adaptive Cruise Control system.Contact an authorized dealer to have the system
checked.
WEAR ON BRAKE PADS
Lights up when the brake pads have reached their wear
limit.Contact an authorized dealer as soon as possible.Note:
Always use genuine parts or similar because the
Integrated Brake System (IBS) system could detect
anomalies.
WEAR ON CCB BRAKE DISCS if equipped)
Lights up when the carbon ceramic brake discs have
reached their wear limit.
Contact an authorized dealer as soon as possible.
Warning!
It is recommended to use only original or equivalent, bench-tested spare pads in order to ensure the original performance of the braking
system.
91

If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery
in another vehicle. This type of start can be
dangerous if done improperly. Refer to
“Emergency Starting” in “In Case Of
Emergency” for further information.
Caution!
To prevent damage to the starter, do not
continuously crank the engine for more
than 25 seconds at a time. Wait
60 seconds before trying again.
After Starting —
Warming Up The Engine
Proceed as follows:Travel slowly, letting the engine run at
a reduced RPM, without accelerating
suddenly.
It is recommended to wait until the
digital engine coolant temperature
indicator starts to rise for maximum
performance.
Stopping The Engine
To stop the engine, proceed as follows:
1. Park the vehicle in a position that is
not dangerous for oncoming traffic.
2. Engage the PARK (P) mode. 3. With engine idling, press the
START/STOP button on the steering
wheel to STOP the engine.
Note:
Do not leave the ignition in ON
mode when the engine is off.
To shut off the engine with vehicle
speed greater than 5 mph (8 km/h), you
must push and hold the ignition or push
the START/STOP button three times
consecutively within a few seconds.
The engine will shut down, and the
ignition will be placed in the ON mode
With the keyless ignition system, it is
possible to go away from the vehicle
taking the key fob with you, without the
engine switching off. The vehicle will
inform about the absence of the key on
board, only if the doors are closed.
Stopping the engine (cycling from the
ON to the STOP position) the
accessories are still powered for about
three minutes, or until a door is opened.
When the ignition is in the STOP/OFF
mode, the window switches remain
active for three minutes. Opening a
front door will cancel this function.
After severe driving, idle the engine to
allow the temperature inside the engine
compartment to cool before shutting off
the engine.
Turbocharger Cool
Down
Before switching the engine off, keep it
idling for a few minutes so that the
turbocharger can be suitably lubricated.
This procedure is particularly
recommended after severe driving.
After a full load operation, keep the
engine idling for three to five minutes
before switching it off.
This time allows the lubricating oil and
the engine coolant to eliminate the
excessive heat from combustion
chamber, bearings, inner components
and turbocharger.
137

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.

SCHEDULED
SERVICING
Correct servicing is crucial for
guaranteeing a long life for the vehicle
under the best conditions.
For this reason, Alfa Romeo has
planned a series of checks and services
for your vehicle at fixed intervals based
on distance and time, as described in
the Scheduled Servicing Plan.
Before each service, it is always
necessary to carefully follow the
instructions in the Scheduled Servicing
Plan (e.g. periodically check level of
fluids, tire pressure, etc.).
Scheduled Servicing is offered by an
authorized dealer according to a set
time schedule. If, during each
operation, in addition to the ones
scheduled, the need arises for further
replacements or repairs, these may be
carried out with owners explicit consent
only.
Note:
Scheduled Servicing intervals are
required by the Manufacturer. Failure to
have them carried out may invalidate
the New Vehicle Limited Warranty.
You are advised to inform your
authorized dealer of any small operating
irregularities without waiting for the next
service.
Periodic Checks
Every month or every600miles
( 1,000 km) or before long trips check
and, if necessary, top off:
Engine coolant level.
Brake fluid level (if insufficient, see
your authorized dealer as soon as
possible).
Windshield washer fluid level.
Tire inflation pressure and condition.
Operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.).

following conditions:
Dusty roads.
Short, repeated journeys less than
4 miles (7-8 km) at sub-zero outside
temperatures.
Engine often idling or driving long
distances at low speeds or long periods
of inactivity.
In the event of a long period of
inactivity. The following checks must be carried
out more often than indicated in the
Scheduled Servicing Plan:
Check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage.
Visually inspect conditions of: engine,
transmission, pipes and hoses
(exhaust/fuel system/brakes) and
rubber elements (sleeves/bushes, etc.).
Check battery charge and battery
fluid level (electrolyte).
Visually inspect conditions of the
accessory drive belts.
Check and, if necessary, change
engine oil and replace oil filter.

Useful Advice For
Extending The Life Of
Your Battery
To avoid draining your battery and
make it last longer, observe the
following instructions:
When you park the car, ensure that
the doors and trunk are closed properly
to prevent any lights from remaining on
inside the passenger's compartment.
Do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running.
Before performing any operation on
the electrical system, disconnect the
negative battery cable.
If, after purchasing the car, you wish to
install electrical accessories that require
permanent electrical supply (e.g. alarm,
etc.), or accessories which influence the
electrical supply requirements, contact
your authorized dealer, whose qualified
staff will evaluate the overall electrical
consumption.
Caution!
If the charge level remains under 50% for a
long time, the battery may be damaged by
sulphation, reducing its capacity and
efficiency at start the vehicle. The battery is
also more prone to the risk of freezing (at
temperatures as high as 14°F (-10°C).
Note:
After the battery is disconnected, the
steering must be initialized. The
warning light on the instrument
panel switches on to indicate this. To
carry out this procedure, simply turn the
steering wheel all the way from one end
to the other, and then turn it back to the
central position.
211

bodywork areas checked at your
authorized dealer to identify any
components which are broken,
damaged, worn or have moved from
their correct fitting position.
Open welding or loose connections
may permit exhaust gas to enter the
passenger compartment.
Have the exhaust system checked
every time the vehicle is raised. Replace
the components where necessary (for
these operations, contact an authorized
dealer).
In normal operating conditions, the
catalytic converter does not require
maintenance. To ensure that it operates
correctly, however, and prevent it from
getting damaged, it is extremely
important that the engine operates
perfectly.
To minimize the risk of damaging the
catalytic converter, proceed as follows:
Do not stop the engine or deactivate
the ignition with gear engaged and
vehicle in motion.
Do not attempt to start the engine
by bump starting.
Do not persist in using the vehicle if
idling is very irregular or the operating
conditions are very notably irregular.
Warning!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you.
A hot exhaust system can start a fire if
you park over materials that can burn.
Such materials might be grass or leaves
coming into contact with your exhaust
system. Do not park or operate your
vehicle in areas where your exhaust system
can contact anything that can burn.
Cooling System
Warning!
Turn vehicle off and disconnect the fan
motor lead before working near the radiator
cooling fan.
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 open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts
automatically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, disconnect the fan motor lead or turn
the ignition to the OFF mode. The fan is
temperature controlled and can start at any
time the ignition is in the ON mode.
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 is hot.
Engine Coolant Check
Check the engine 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 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
