Additional Notes
- The Audi Q3 F3 (USA) cooling system holds 10 liters across all four configurations covered in the specifications, which is a total system capacity representing the full volume of coolant the engine and associated passages can hold when filled from empty.
- The 10-liter capacity applies equally to both the 40 TFSI quattro (137 kW) and the 45 TFSI quattro (170 kW) variants, meaning the higher-output engine does not carry a larger cooling system volume under normal use conditions.
- The Q3 40 TFSI quattro (137 kW) carries the same 10-liter cooling system capacity across both the 2018-2021 configuration and the 2021 onward configuration, indicating no change in system volume between those two specification entries.
- The Q3 45 TFSI quattro (170 kW) similarly shows no variation in cooling system capacity between the 2018-2021 and 2021 onward entries, with both specifying 10 liters under normal use conditions.
- The service interval for coolant inspection is set at 20,000 miles or 24 months, whichever comes first, across all four configurations. The dual-trigger format means time elapsed can prompt a check even when mileage accumulation is low.
- All four rows carry a normal use condition designation tied to the 20,000-mile and 24-month check interval, meaning the specified schedule reflects standard operating conditions rather than a reduced interval associated with more demanding use.
