Mercedes SL 350 FAQ's

How do I change a flat tire on my Mercedes SL 350?

To change a flat tire on your Mercedes SL 350, first, ensure that the vehicle is parked on a flat and stable surface. Locate the spare tire, jack, and lug wrench in the trunk or under the vehicle.

To check the transmission fluid level in your Mercedes SL 350, ensure that the engine is warm and the vehicle is on a level surface.
