Scheduled Servicing Overview

The 2023 Alfa Romeo Giulia 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 .

Plan Notation:

• (o) Recommended operations - suggested for optimal vehicle health
• (mandatory) Mandatory operations - required to maintain warranty coverage

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 600 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 .

Factory Maintenance Plan - 2.0L Engine with AWD

The following maintenance requirements are extracted from the official 2023 Alfa Romeo Giulia Owner's Manual :

Regular Inspections (Every 10,000 miles / 1 year) :

• Check battery charge status with proper instrument (mandatory)
• Check tire condition/wear and adjust pressure; check tire repair kit condition (mandatory)
• Check operation of lighting system (mandatory)
• Check and top up fluid levels (mandatory)
• Check engine control system via diagnostic tool; check engine oil degradation (mandatory)
• Visually inspect exterior bodywork, underbody protection, pipes/hoses, rubber elements (mandatory)
• Check position/wear of front windshield wiper blade (mandatory)
• Check operation of wiper/washer system and adjust nozzles (mandatory)
• Check cleanliness of hood and trunk locks and linkage (mandatory)
• Visually inspect front/rear disc brake pads and wear indicators (mandatory)
• Visually inspect condition and tensioning of accessory drive belt(s) (mandatory)

Oil Degradation Monitoring:

If the oil degradation ratio (data collectable from the diagnostic device) is more than 80% (oil quality less than 20%), engine oil and filter replacement is recommended .

Transfer Case Service - AWD Only

The transfer case in the Giulia AWD enables power transfer between the front and rear wheels. It contains chain-driven gears that splash 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 .

How Often Replacement is Needed:

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
• Recent 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 Giulia 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 .

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 Oil Change Requirement :

Vehicles that are operated in a dusty and off-road environment, or predominantly at idle or very low engine RPM, are known as Severe Duty vehicles. It is recommended that you change engine oil at 4,000 miles (6,500 km) or 350 hours of engine run time.

Oil Level Checking :

• Check engine oil level every 1,860 miles (3,000 km)
• It must be checked once full operating temperature is reached
• Top off if necessary

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

When You May Need an Oil Change Sooner :

• Check engine light is on
• Knocking noise coming from the engine
• Oil smell inside the vehicle
• Excess amount of vehicle exhaust
• Hauling heavy loads
• Driving in dusty terrain or off-road
• Driving at low speeds for long distances

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, see an authorized dealer as soon as possible .

Carbon Ceramic Brakes (if equipped): For Quadrifoglio models with carbon ceramic brake discs, the actual interval for changing brake pads and discs depends on vehicle usage conditions and is signaled by a warning light on the instrument panel. After each disc replacement, the warning light must be reset using the diagnostic socket .

Spark Plugs

Replacement Interval :

• NAFTA market: 60,000 miles
• Other markets: 60,000 km

Important: The spark plug change interval is mileage-based only - yearly intervals do not apply . Use only spark plugs specified by Alfa Romeo for the Giulia engine. Incorrect plugs can cause misfires, poor fuel economy, and engine damage.

Engine and Cabin Air Filters

Standard Intervals:

Follow the maintenance schedule for replacement. The cabin air filter alternates between recommended (o) and Mandatory operations at most service intervals .

Dusty Area Requirement :

• If the vehicle is used in dusty areas, the engine air cleaner and cabin air filter must be replaced every 10,000 miles (16,000 km)

Accessory Drive Belt

Accessory Drive Belt Inspection:

Visual inspection of condition and tensioning is required at every scheduled service (every 10,000 miles) .

Accessory Drive Belt Replacement :

• First replacement at 18,000 miles
• Final replacement at 150,000 miles
• The accessory drive belt(s) replacement is listed as a mandatory operation in the maintenance plan

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.

SOS Backup Battery (If Equipped)

If your Giulia is equipped with an SOS backup battery (for the emergency call system), it must be replaced every 5 years, regardless of mileage . This appears as a mandatory operation at the 5-year, 10-year, and 15-year intervals in the maintenance plan.

Engine Coolant

Engine coolant replacement is listed as a mandatory operation in the maintenance plan, scheduled at 150,000 miles (10 years) . Coolant level should be checked monthly (every 600 miles) and topped off as needed .
