5 Insert cap with dipstick (2a) into supply reservoir (2), pull back out and read off fluid level on dipstick (2a)

NOTE:
- The fluid level can only be measured correctly when the vehicle is unladen.
- Read off fluid level on dipstick (2a) on the side with the inscription "ENGINE OFF UNLADEN".
- The fluid level must be between the "MIN" and "MAX" marks.

6 If the fluid level is too low, locate and rectify the cause

NOTE: Check the entire hydraulic system for leaks.

CAUTION: Before opening the ABC system, thoroughly clean the area around the separation point. Even the smallest dirt particles introduced into the hydraulic components can lead to malfunctions and a total failure of the ABC system.

7 Correct fluid level

CAUTION: Only use the funnel (060) with filter for filling hydraulic fluid. The funnel (060) must not be used with other operating fluids. To avoid contamination in the ABC system, the funnel (060) must be kept in a locked cabinet.
