Left Side:

Right Side:

CAUTION: Under no circumstances should the power steering pump draw in air.

NOTE: If air is drawn in by the power steering pump an air cushion may form in the low pressure chamber of the steering gear which is only eliminated after a longer trip (> 50 km)

1 Fill up reservoir of power steering pump to approx 10 mm below upper edge of reservoir
2 Start engine 2-3 times.

NOTE: The steering system bleeds itself automatically

3 Turn the steering from lock to lock several times with the engine running, meanwhile topping up with MB steering gear fluid if necessary.
4 Power steering - check and correct fluid level
5 Check steering system for leaks

NOTE:
- A slight fluid film on the radial shaft sealing ring or on the contact face of the housing is due to the design
- If the fluid level is too low, establish and eliminate the cause.
