Scheduled Servicing Overview

The 2023 Alfa Romeo Stelvio AWD follows a structured maintenance plan based on both distance and time intervals, as detailed in the official owner's manual. Correct servicing is crucial for guaranteeing a long life for the vehicle under the best conditions .

How the System Works:

• Alfa Romeo has planned a series of checks and services at fixed intervals based on distance and time
• Scheduled Servicing is offered by an authorized dealer according to a set time schedule
• Before each service, follow the instructions in the Scheduled Servicing Plan (periodically check fluid levels, tire pressure, etc.)
• If additional replacements or repairs are needed beyond scheduled operations, they require the owner's explicit consent

Critical Warranty 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 an authorized dealer of any small operating irregularities without waiting for the next service .

Oil Change Indicator System:

The actual interval for changing engine oil and replacing the engine oil filter depends on vehicle usage conditions and is signaled by the warning light or message in the instrument panel . The system adapts depending on your driving habits - it may be as soon as 3,500 miles or as far away as 10,000 miles, but regardless of the indicator, a synthetic oil and oil filter change should occur no later than 10,000 miles or 12 months, whichever occurs first . In all cases, never exceed 1 year/10,000 miles (16,000 km) .

Owner Periodic Checks (Between Services)

The following checks are the owner's responsibility between professional service visits. These should be performed every month or every 620 miles (1,000 km) or before long trips :

Engine Oil Level:

Oil consumption depends on conditions and driving style. The engine oil level must be checked every 1,860 miles (3,000 km) and topped off if necessary .

Heavy Usage & Severe Duty Conditions

If the vehicle is used under any of the following conditions, more frequent maintenance is required :

Checks Required More Frequently Under Heavy Usage :

• Check cleanliness of hood and liftgate 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
• Check and, if necessary, replace cabin air filter
• Check and, if necessary, replace air cleaner

Severe Duty - All Models :

Change engine oil at 4,000 miles (6,500 km) if the vehicle is operated in a dusty and off-road environment or is operated predominately at idle or only very low engine RPM. This type of vehicle use is considered Severe Duty.

Factory Maintenance Plan - 2.0L Engine with AWD

The following maintenance plan is extracted from the official 2023 Alfa Romeo Stelvio Owner's Manual. The table shows key Mandatory and recommended (o) operations at mileage and year intervals :

Thousands of miles / Years / Thousands of kilometers

Plan Footnotes (from owner's manual) :

• (1) The actual interval for changing engine oil and replacing the oil filter depends on vehicle usage conditions and is signaled by the warning light or message in the instrument panel. Never exceed 1 year/10,000 miles (16,000 km) in all cases.
• (2) The SOS backup battery must be replaced every five years, regardless of mileage.
• (3) Top up using the fluids indicated, only after checking that the system is intact .

Complete Service Schedule by Mileage - 2.0L AWD

Below is a simplified summary of the factory plan :

10,000 - 50,000 Miles

60,000 - 100,000 Miles

110,000 - 150,000 Miles

Note on Accessory Drive Belt Replacement: The factory plan shows mandatory replacement at 150,000 miles/15 years . However, independent schedules show replacement at 18,000 and 36,000 miles for normal conditions . For non-dusty areas, the recommended maximum is 36,000 miles (60,000 km) or every 4 years. For dusty areas and/or demanding use, replace at 18,000 miles (30,000 km) or every 2 years .

Transfer Case Service - AWD Only

The transfer case oil replacement is a mandatory operation for AWD models only. The 2023 factory maintenance plan shows this as a Mandatory operation at the 150,000-mile/15-year service interval . Independent schedules also note transfer case fluid replacement at 80,000 miles .

The transfer case enables power transfer between the front and rear wheels. It contains chain-driven gears that move through specialized fluid to keep components cool, well-lubricated, corrosion-free, and to prevent wear and tear .

Why Transfer Case Fluid Requires Replacement:

During normal driving, the transfer case fluid is exposed to heat and friction, which gradually break down the fluid and cause it to lose its lubricating properties. When the fluid has become dark or gritty, around the time of its service interval, it will need to be changed .

General Interval Context:

Transfer case fluid replacement intervals vary by manufacturer, typically ranging from 40,000 km to 100,000 km and beyond. Heavy off-road use or towing can break down transfer case fluid faster, meaning shorter service intervals .

Symptoms That Indicate Transfer Case Service is Needed :

• Transfer case fluid is dark and discolored
• Transfer case fluid level is low
• Repairs have been completed on the transfer case
• Rattle or grinding noise coming from underneath your car

Critical Warning: When the transfer case fluid is replaced, only the exact manufacturer-specified fluid should be used - using the incorrect fluid will cause premature failure. Like poor engine oil maintenance, transfer case problems will eventually occur if transfer case fluid replacement is neglected .

Consequences of Neglect:

Driving your Alfa Romeo Stelvio with neglected transfer case maintenance can lead to a breakdown and possible loss of control. Have your transfer case fluid replacement performed in a timely manner .

Engine Oil Change Guidance

Oil Change Indicator System:

The actual interval for changing engine oil and replacing the engine oil filter depends on the vehicle usage conditions and is signaled by the warning light or message in the instrument panel . It may be as soon as 3,500 miles or as far away as 10,000 miles, but the system adapts depending on your driving habits to determine how much life is still left in your crankcase .

Maximum Limits:

• Never exceed 1 year between oil changes
• Never exceed 10,000 miles (16,000 km) between oil changes
• The warning light may indicate a need for earlier changes based on driving conditions

Severe Duty: 4,000 miles (6,500 km) if operated in dusty/off-road environments or predominantly at idle/low RPM .

At Every Oil Change (as indicated by the system):

The maintenance plan includes a comprehensive vehicle inspection at each oil change interval, including brake system inspection, battery check, tire check, and accessory drive belt condition check .

CAUTION: Never overfill the engine with oil. Excess oil can damage the engine. Never exceed the MAX level when topping up.

Brake Fluid

Brake fluid replacement is a mandatory operation that must be done every 2 years, irrespective of mileage .

Why Every 2 Years:

Brake fluid is hygroscopic - it absorbs moisture from the air over time, which lowers the boiling point and can cause brake fade under hard braking. Moisture also promotes internal corrosion of brake system components.

Owner Check: If the brake fluid level is insufficient during the monthly check, see an authorized dealer as soon as possible .

Spark Plugs

Replacement Interval :

• NAFTA market: 60,000 miles
• Other markets: 60,000 km
• Yearly intervals do not apply

Important: The spark plug change interval is mileage-based only. Use only spark plugs specified by Alfa Romeo for the Stelvio engine. Incorrect plugs can cause misfires, poor fuel economy, and engine damage.

Replacement Schedule in the Plan: Spark plugs are shown as Mandatory replacements at 30,000, 60,000, 90,000, 120,000, and 150,000 miles .

Owner Forum Note: Some owners recommend replacing spark plugs earlier than the factory interval - suggestions range from 20,000 to 30,000 miles for optimal performance .

Accessory Drive Belt

The accessory drive belt(s) require visual inspection of condition and tensioning at every scheduled service through 120,000 miles .

Replacement Intervals :

Factory Schedule Note: The maintenance plan shows accessory drive belt replacement as a Mandatory operation at 150,000 miles/15 years . However, independent schedules show replacement at 18,000 and 36,000 miles , and the owner's manual footnotes indicate the 36,000-mile/4-year interval for non-dusty areas .

Owner Guidance: When replacing belts, consider replacing tensioners as well. The highest cost of this service is the labor, not the replacement part itself. Reusing old tensioners risks premature failure and repeating the entire expense.

Engine and Cabin Air Filters

Engine Air Cleaner Cartridge :

• Normal conditions: Replace per maintenance schedule (shown at 30,000, 60,000, 90,000, 120,000, and 150,000-mile intervals)
• Dusty areas: Replace every 10,000 miles (16,000 km)

Cabin Air Filter :

• Normal conditions: Alternating recommended (o) and Mandatory operations at most service intervals (every 10,000 miles)
• Dusty areas: Replace every 10,000 miles (16,000 km)
• Independent schedules show cabin air filter replacement at every 10,000-mile interval

Engine Coolant

Engine coolant replacement is a mandatory operation in the maintenance plan, scheduled at 150,000 miles (15 years) . Coolant level should be checked monthly (every 620 miles) and topped off as needed .

WARNING: Never open a cooling system pressure cap when the radiator or coolant bottle is hot. Never add engine coolant when the engine is overheated.

SOS Backup Battery (If Equipped)

If your Stelvio is equipped with an SOS backup battery (for the emergency call system), it must be replaced every 5 years, regardless of mileage . The maintenance plan shows this as a mandatory operation at the 5-year (50,000 miles), 10-year (100,000 miles), and 15-year (150,000 miles) intervals .

Additional Service Components

Fuel Filter:

Replacement of the additional fuel filter (if equipped) is required at every 10,000-mile service interval as a mandatory operation .

Battery:

Check battery charge status with the proper instrument at every scheduled service (every 10,000 miles / 1 year) .

Tires:

• Check tire condition/wear and adjust pressure at each service
• Check the tire repair kit recharge condition and expiration date
• Tire rotation is recommended every 10,000-12,000 miles for even wear

Brake System:

Visually inspect conditions and wear of front/rear disc brake pads and operation of pad wear indicators at every service .

Lighting System:

Check operation of headlights, direction indicators, hazard warning lights, trunk lid lights, passenger compartment lights, glove compartment lights, and instrument panel warning lights at each service .

Wiper System:

Check position/wear of front windshield wiper blades and operation of the windshield wiper/washer system at every 10,000-mile service .

Bodywork Lubrication:

Using white lithium grease, lubricate the door hinge and roller pivot joints twice a year to prevent premature wear .

Maintenance Plan - 2.9L V6 Engine (Quadrifoglio)

For the 2023 Stelvio Quadrifoglio (2.9L V6), the maintenance plan shares many of the same inspection requirements as the 2.0L engine, including SOS backup battery replacement, battery charge checks, tire checks, lighting checks, fluid level checks, and engine control system diagnostics .

Quadrifoglio-Specific Notes :

• The instrument panel warning light signals when service is due
• Brake pad/brake disc replacement interval depends on vehicle usage conditions and is signaled by a warning light on the instrument panel
• For carbon ceramic brakes, after each disc replacement, the warning light must be reset using the diagnostic socket

Note: Owners of Quadrifoglio models should consult the owner's manual's Quadrifoglio section for specific spark plug and other interval details, as the 2.9L engine has different requirements than the 2.0L.
