Additional Notes
- All three configurations in the Mercedes-Benz SLK-Class R172 lineup share an identical power steering fluid capacity of 1 liter, covering the SLK 250 (172.447), SLK 350 (172.457), and SLK 55 AMG (172.475).
- A 1-liter capacity is characteristic of a relatively compact hydraulic power steering reservoir, consistent with the space constraints typical of a two-seat roadster platform.
- The SLK 250 and SLK 350 carry a model year span of 2011-2015 for power steering fluid specifications, while the SLK 55 AMG carries a span of 2012-2015.
- All three configurations list normal as the use condition tied to the 1-liter capacity figure, meaning the specification applies to standard operating conditions rather than a severe-duty or first-fill scenario.
- No variation in power steering fluid capacity exists across the three engine variants, indicating the R172 platform uses a uniform reservoir size regardless of whether the engine is the turbocharged four-cylinder, the naturally aspirated V6, or the AMG V8.
