Factory Service Schedule

The 2021 Aston Martin DBX follows a structured maintenance schedule requiring service every 12 months or 16,000 km (approximately 10,000 miles), whichever comes first . This 4.0L twin-turbo V8 luxury SUV demands regular attention to maintain its 542-horsepower output and sophisticated engineering.

The maintenance schedule is divided into 16,000 km/12-month intervals . The official DBX owner's manual contains the complete maintenance schedule, covering oil changes, tire rotations, brake inspections, and fluid checks to keep the vehicle running smoothly .

Each item in the service schedules must be performed on time, as failure to do so may void the New Vehicle Warranty or other warranties. It is the owner's responsibility to ensure the vehicle is maintained correctly in accordance with the manufacturer's service schedules .

Service Interval Summary

The annual service schedule may be modified if necessary. Consult your Aston Martin Dealer for details of any service schedule updates .

Annual Service Inspection Items

At each annual service, Aston Martin specifies a comprehensive inspection of the following systems and components :

• Engine and transmission mounting system (check for leaks)
• Accessory drive belt
• Fuel system (examine for leaks and wear)
• Cooling system (examine for leaks)
• Air conditioning system
• Drive shafts
• Wheel arch liners and under body protection
• Suspension and steering system (examine for leaks and wear)
• Brake system including park brake (examine for leaks and wear)
• Wheels, tires and tire pressure monitoring system (check pressures and adjust)
• Exhaust system, heat shields and bypass valves (check for leaks)
• Lamp units and the vehicle horn
• Windscreen wiper blades and wash system (check fluid levels, examine for leaks and wear)
• Occupant restraint systems including airbags, seatbelts and child seat attachment points
• Locks, latches and hinges (check powered openings for correct operation; lubricate joints)
• Instrument cluster and warning symbols

Engine Oil Service

Oil Change Interval

The 4.0L twin-turbo V8 in the DBX requires a synthetic oil and filter change at the 16,000 km or 12-month service interval . The engine oil should be changed and the oil filter replaced at each major service.

Owner Oil Level Check

Caution: It is important to check the engine oil level regularly. Running the engine with engine oil below the lower mark or above the upper mark can cause serious engine damage . Check the engine oil level every fourth fuel tank fill or weekly, whichever is sooner .

Parts and Lubricants Warning

Aston Martin recommends using the specified lubricants and parts when performing service tasks. If oils or lubricants that do not meet the required fluid specifications are used, vehicle components may experience excessive wear, sludge and deposits, or increased pollution. If it is evident to Aston Martin that use of products other than those recommended by the manufacturer have caused damage, Aston Martin may refuse to authorise the repair of such damage under the terms of the manufacturer's warranty .

Brake Fluid Service

Replacement Interval

Brake fluid replacement is generally recommended every two years . The 32,000 km / 24-month service includes brake fluid replacement . This safety-critical service should not be deferred. Brake fluid absorbs moisture over time, which reduces its boiling point and can lead to brake fade under hard use.

The brake fluid level should be checked weekly as part of routine owner maintenance .

Air Filter Service

Ancillary Drive Belt Service

The ancillary drive belt is scheduled for replacement at the 48,000 km / 36-month service interval . This is a critical maintenance item that should not be deferred, as belt failure can lead to loss of alternator, power steering, or air conditioning function.

Service Interval Reset

Aston Martin has found that the service interval timer starts during the manufacturing process. For vehicles which have spent time in stock or storage, the service interval timer must be reset during the customer handover process . The DBX uses the instrument cluster process to reset the service interval. A Technical Service Bulletin (SB-30-1669) addresses this process for DBX models .

Extended Maintenance Guidance

The following table summarizes additional maintenance items for long-term ownership planning:

Note: Always verify exact intervals for your specific vehicle in the official owner's manual.

The DBX features a timing chain rather than a timing belt. Unlike timing belts, timing chains are designed to last the life of the engine under normal driving conditions and do not require scheduled replacement.

Owner Maintenance Checks

In the interests of safety and reliability, the owner's manual recommends carrying out the following checks at the suggested intervals (more frequently if the vehicle is heavily used or operating in adverse conditions), and always before starting on a long journey :

Before Use Checks:

• Operation of lamps, horn, indicators, wipers, washers, and warning symbols
• Sufficient fuel for the intended journey, particularly at night and before entering motorways
• Operation of the seat belts
• Operation of the brakes
• Check for fluid deposits underneath the vehicle

Weekly Checks:

• Tyre condition
• Coolant level
• Brake fluid level
• Air conditioning operation
• Windscreen washer fluid level
• Check operation of windscreen washers
• Fuel filler bowl (check drain pipe is free from debris)

Extended Warranty and Service Plans

The 2021 DBX is protected by a 3-year/unlimited mileage vehicle warranty and a 10-year/unlimited mileage anti-perforation warranty from new . At the end of the factory warranty period, Aston Martin offers extended warranty coverage. An optional extended Premium service contract can extend from two years all the way out to 10 years with unlimited mileage, subject to a multi-point Aston Martin inspection .
