check engine Alfa Romeo Stelvio 2018 Owner's Guide

The vehicle is equipped with an
Intelligent Battery Sensor (IBS), which is
able to measure the charge and discharge
voltage and calculate the charge level
and the general condition of the battery.
The sensor is placed next to the negative
terminal (-) of the battery.For a correct charge/discharge
procedure, the charge voltage must go
through the IBS sensor.
1. Turn the charger on and follow the
instructions on the user's manual to
completely recharge the battery.
2. When the battery is charged, turn the
charger off before disconnecting it from
the battery.
3. Disconnect the black cable terminal of
the battery charger and then the red
cable terminal.
4. Refit the protective cover of the
positive terminal of the battery and the
access cover to the battery
compartment.
Note:
If a "quick-type" battery charger is
used with the battery fitted on the
vehicle, before connecting it disconnect
both cables of the battery itself. Do not
use a "quick-type" battery charger to
provide the starting voltage.
DEALER SERVICE
The following pages contain instructions
on the required maintenance from the
technical personnel who designed the
vehicle.
In addition to these specific maintenance
instructions specified for routine
scheduled servicing, there are other
components which may require periodic
maintenance or replacement over the
vehicle’s life cycle.
Engine Oil
Engine Oil Level Check
To ensure correct engine lubrication, the
oil must always be kept at the prescribed
level (see "Engine Compartment" in this
chapter).
Check the oil level at regular intervals, for
example every 1,864 miles (3,000 km).
It must be checked about five minutes
after stopping the engine.
Full operating temperature must be
reached. The vehicle must also be parked
on as level a surface as possible.
The engine oil level can be checked using
the Information and Entertainment
system. To access the function, activate
the main menu (MENU button) and select
the following options in sequence:
1. “Applications”
2. “My Car”
3. “Oil level”

Ensure that the oil level is within the
interval on the dipstick between the
minimum and maximum limits
(Quadrifoglio only).
Changing The Engine Oil
See the "Maintenance Plan" for the
correct servicing intervals.
Choice Of Engine Oil Type
To ensure optimal performance and
maximum protection in all operating
conditions, it is advised to use certified
engine oils. Refer to "Fluid And
Lubricants" in "Technical Specifications"
for further information.
Additives For Engine Oil
It is strongly recommended not to use
additives (other than leak detection dyes)
with the engine oil.
The engine oil is a product designed
specially for the vehicle and its
performance may be deteriorated
through the use of further additives.
Disposal Of Used Engine Oil And Filters
For the disposal of the engine oil and
filters, contact the appropriate body to
determine local regulations.
Note:Used engine oil disposed of
incorrectly may seriously harm the
environment.Engine Oil Filter
Replacing the Engine Oil Filter
The engine oil filter must be replaced
each time the engine oil is changed. It is
advised to replace it with a genuine spare
part, specifically designed for this
vehicle.
Air Filter
Replacing the Air Cleaner
See the "Maintenance Plan" for the
correct servicing intervals. It is advised to
replace it with a genuine spare part,
specifically designed for this vehicle.
Air Conditioning System Maintenance
To ensure the best possible performance,
the air conditioning system must be
checked and undergo maintenance at an
authorized dealer at the beginning of the
summer.
Caution!
Do not use chemicals to clean the air
conditioning system, since the internal
components may be damaged. This kind of
damage is not covered by warranty.
Replace The Cabin Air Filter
See the "Maintenance Plan" for the
correct servicing intervals. For cleaner
replacement, contact an authorized
dealer.
Warning!
Use only refrigerants and compressor
lubricants approved by the manufacturer for
your air conditioning system. Some
unapproved refrigerants are flammable and
can explode, injuring you. Other unapproved
refrigerants or lubricants can cause the
system to fail, requiring costly repairs. Refer
to Warranty Information Book, located in
your owner’s information kit, for further
warranty information.
Lubricating Moving Parts Of The
Bodywork
Ensure that the locks and bodywork
junction points, including components
such as the seat guides, door hinges (and
rollers), liftgate and hood are periodically
lubricated with lithium-based grease to
ensure correct, silent operation and to
protect them from rust and wear.
Thoroughly clean the components,
eliminating every trace of dirt and dust.
After lubricating, eliminate excess oil and
grease. Also pay particular attention to
the hood closing devices, to ensure
correct operation. During operations on
the hood, to be carried out with the
engine cold, also remember to check,
clean and lubricate the locking, release
and safety devices.

SERVICING AND MAINTENANCE

Replacing The Windshield Wiper Blades
Proceed as follows:
1. Raise the wiper arm, push tab of the
attachment spring and remove the blade
from the arm.
2. Fit the new blade, inserting the tab in
the dedicated housing in the arm and
checking that it is locked.
3. Lower the wiper arm onto the
windshield.
Note:Do not operate the windshield
wiper with the blades lifted from the
windshield.
Front/Rear Windshield Washers
The window washer nozzles are fixed. If
there is no jet of fluid, first check that
there is fluid in the reservoir. Refer to
“Engine Compartment” in this chapter for
the reservoir location. Then, check that the nozzle holes are not
clogged; use a needle to unblock them if
necessary.
Exhaust System
Adequate maintenance of the engine
exhaust system represents the best
protection against leaks of carbon
monoxide into the passenger
compartment.If an unusual noise from the exhaust or
the presence of smoke in the passenger
compartment is identified, or if the
underbody or rear section of the vehicle
have been damaged, have the entire
exhaust system and adjoining 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.

SERVICING AND MAINTENANCE

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!
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.
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.
223

Note:
For topping up, refer to "Fluids And
Lubricants" in "Technical Specifications"
for proper coolant specifications.
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.
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.

SERVICING AND MAINTENANCE

STORING THE VEHICLE
If the vehicle is left inactive for longer
than a month, the following precautions
should be observed:
Park the vehicle in an area that is
covered and dry, and well-ventilated if
possible. Slightly open the windows.
Check that the electric park brake is
not activated.
Carry out the “Liftgate Emergency
Opening” procedure described in the
“Power Liftgate” section of “Getting To
Know Your Vehicle”.
Disconnect the negative battery
terminal and check the battery charge.
Repeat this check once every three
months during storage.
If the battery is not disconnected from
the electrical system, check its state of
charge every thirty days.
Clean and protect the painted parts
using protective wax.
Clean and protect the shiny metal
parts using special compounds available
commercially.
Sprinkle talcum powder on the
windshield wiper rubber blades, and lift
them off the glass.
Cover the vehicle with a fabric or
perforated plastic sheet, paying
particular care not to damage the painted
surface by dragging any dust that may have accumulated on it. Do not use
compact plastic sheets, as they do not
allow humidity to evaporate from the
surface of the vehicle.
Inflate tires to +7.25 psi (+0.5 bar)
above the standard prescribed pressure
and check it periodically.
Do not drain the engine cooling
system.
Any time the vehicle is left inactive for
two weeks or more, operate the air
conditioning system with engine idling
for at least five minutes, setting external
air and with fan set to maximum speed.
This operation will ensure appropriate
lubrication for the system, thus
minimizing the possibility of damage to
the compressor when the system is
operated again.
Note: After cycling the ignition to STOP
and having closed the driver side door,
wait at least one minute before
disconnecting the electrical supply from
the battery. When reconnecting the
electrical supply to the battery, make
sure that the ignition is in the STOP
position and the driver’s side door is
closed.
BODYWORK
Protection Against Atmospheric
Agents
The vehicle is equipped with the best
available technological solutions to
protect the bodywork against corrosion.
These include:
Painting products and systems which
give the vehicle resistance to corrosion
and abrasion.
Use of galvanized (or pre-treated)
steel sheets, with high resistance to
corrosion.
Spraying of plastic parts, with a
protective function in the more exposed
points: underdoor, inner wing, edges, etc.
Use of “open” boxed sections to
prevent condensation and pockets of
moisture which could favor the formation
of rust inside.
Use of special films to protect against
abrasion in exposed areas (e.g. rear wing,
doors, etc.).
Corrosion Warranty
Your vehicle is covered by Corrosion
Warranty against perforation due to rust
of any original element of the structure
or bodywork. For the general terms of
this warranty, refer to the Warranty
Booklet.
