2021 ALFA ROMEO STELVIO Owners Manual

223

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 use the vehicle if irregular idling or
operating conditions are experienced.
Cooling System
Coolant Check
Your vehicle has two cooling systems and both
need to be checked to ensure they are at
proper fill levels
Ú
page 214.
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 for any
build-up of insects, leaves or other debris.
Should it be dirty, clean 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.

NOTE:

Before removing the coolant reservoir cap,
wait for the system to cool down.
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.
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 open a cooling system pres
-
sure 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 automat -
ically 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. 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 over -
heated engine. Heat causes pressure to
build up in the cooling system. To prevent
scalding or injury, do not remove the pres -
sure 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.

Topping Up / Draining / Flushing The Engine/
Intercooler Coolant
If the engine coolant (antifreeze) is dirty, have
cleaning and flushing carried out at an autho
-
rized dealer.
For the correct servicing intervals

Ú
page 209.

NOTE:

For topping off, and proper coolant specifi -
cations
Ú
page 263.
Do not use pure water, alcohol-based cool -
ants, 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. Disposal of Used Coolant
Disposal of engine/intercooler coolant is
subject to legal requirements. Contact the
appropriate body to determine local regula
-
tions.

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 the
front of the hood. This is a normal phenom -
enon 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 compo -
nents; for this operation, contact an autho -
rized dealer.

For the correct servicing intervals

Ú page 209.
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 reser-
voir (in the engine compartment)
completely closed.
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.
WARNING! (Continued)
WARNING!
Use only manufacturer's recommended
brake fluid
Ú
page 263. 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.

Automatic Transmission
Use only a transmission oil with the character-
istics indicated
Ú
page 263.
Special Additives
Do not use any type of additive with the auto -
matic transmission oil. The automatic trans -
mission oil is a product designed specially for this vehicle and its performance may be
compromised through the use of further addi
-
tives.
Frequency of Oil Changes
In normal vehicle operating conditions, it is not
necessary to change the transmission oil.
Replacing The Battery
If necessary, replace the battery with another
battery with the same specifications. It is
advised to contact an authorized dealer for
replacement.
Follow the battery manufacturer's instructions
for maintenance.
Fuses
General Information
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check
the electrical circuit inside of the fuse for a
break/melt.
Also, please be aware that using power outlets
for extended periods of time with the engine
off may result in vehicle battery discharge.
Blade Fuses
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.
WARNING! (Continued)
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.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
