How do you fill power steering fluid Mercedes c240?

To fill the power steering fluid in a Mercedes C240, follow these steps: Locate the power steering fluid reservoir. It is typically a clear plastic canister with a black cap, located in the engine bay near the brake master cylinder. Remove the cap of the power steering fluid reservoir. Check the fluid level. It should be between the "MIN" and "MAX" marks on the reservoir. If the fluid level is low, add enough power steering fluid to bring it up to the correct level. Use only power steering fluid that is recommended by Mercedes-Benz. Reinstall the cap on the power steering fluid reservoir. Start the engine and let it run for a few minutes. Turn the steering wheel from lock to lock a few times to circulate the power steering fluid. Check the fluid level again and add more if necessary.
