The SLK 350 model car is a Mercedes-Benz roadster. It has two doors. This Mercedes can only seat two passengers as many roadsters often do. It comes in many colors.
Mercedes-Benz SLK-Class was created in 1997.
One way to fix a slow steering return on a Mercedes SLK 350 is to add more power steering fluid. Another option is to replace the steering wheel lock sensor.

It should tell you in the handbook. For the SLK it is turn the steering from lock to lock whilst the engine is running. May be the same for other Mercedes.
