FLUID LEVEL CHECK 450 Series Sedans, 300TD and 6.9 Models
The hydro-pneumatic suspension uses a special oil. See the list of approved oils in the beginning of this section.
The car should be level and the engine warm.
- Remove the cover from the oil reservoir. The reservoir is located at the driver's side front corner of the engine compartment.
- Remove the dipstick and wipe it clean.
- Reinsert the dipstick and read the oil level. It should be between the maximum and minimum marks on the dipstick. There is about 2 pts between the "max" and "min" levels.
