Step-by-Step Guide
1. Locate the Transmission Fluid Dipstick
- Open the hood of your Mercedes C300.
- Locate the transmission fluid dipstick. It is typically located near the rear of the engine, towards the passenger side. The dipstick will have a red or orange handle.

3. Reinsert and Remove the Dipstick
- Insert the dipstick back into the transmission until it stops.

4. Check the Fluid Level
- The fluid level should be between the “MIN” and “MAX” marks on the dipstick.
- If the fluid is below the “MIN” mark, add fluid as needed.
- If the fluid is above the “MAX” mark, it may be overfilled and should be drained.
5. Add Fluid if Necessary
- If the fluid level is low, use a funnel to add transmission fluid through the dipstick tube.
- Add fluid gradually and check the level frequently until it reaches the “MAX” mark.
6. Check for Leaks
- Once the fluid level is correct, wipe off any spilled fluid and inspect the area around the transmission for any leaks.
- If you notice any leaks, have them repaired immediately by a qualified mechanic.
7. Reset the Transmission Fluid Counter
- If your Mercedes C300 has a transmission fluid counter, reset it after checking the fluid level.
- Consult your vehicle’s owner’s manual for specific instructions on resetting the counter.
