Oil Capacity:
Approximately 10.5 liters (11.1 US quarts) of engine oil.
Oil Specification:
Likely fully synthetic, viscosity grade 5W-30 or 0W-40, meeting appropriate API and ACEA specifications (e.g., API SL/SM, ACEA A3/B4). Refer to manual for exact Aston Martin approved specification.
Coolant Capacity:
Approximately 12 liters (12.7 US quarts).
Coolant Specification:
Ethylene glycol-based coolant, typically a long-life silicate-free or low-silicate formulation. Aston Martin specification should be followed.
Type:
ZF 6HP26 6-speed automatic transmission.
Type:
No manual transmission option was generally available for the 2007 DB9 in most markets, though very limited numbers might exist for specific regions.
Modes:
Sport mode, manual shifting via paddle shifters (standard feature).
Capacity:
Approximately 10.5 liters (11.1 US quarts) for a complete fluid change.
Specification:
ZF TE-ML 11, Lifeguardfluid 6. Refer to manual for exact Aston Martin approved fluid.
Crash Test Results:
As a low-volume luxury sports car, official comprehensive crash test ratings from organizations like NHTSA or Euro NCAP are typically not available. However, designed to meet rigorous safety standards.
Electronic Stability Control:
Yes, with traction control.
Anti Lock Braking System:
Yes (ABS), often with electronic brake-force distribution (EBD) and emergency brake assist (EBA).
Airbags:
Front airbags for driver and passenger, side airbags, potentially curtain airbags.
Seatbelts:
Pre-tensioning seatbelts with force limiters.
Minor Service:
Typically every 10,000 miles or 12 months, whichever comes first. Includes oil and filter change, general inspection.
Major Service:
Typically every 20,000 miles or 24 months, including brake fluid flush, cabin filter replacement, spark plug replacement (may vary by mileage). Exact intervals should be confirmed with the manual.
Brake Fluid:
