Sequence of work
1. Open the reservoir cap and remove it along with the dipstick.
Pic. 7.15. At a temperature of the working fluid of about + 20°C, its level should be between the two marks on the dipstick
2. Power steering fluid level (at an air temperature of about +20°С) must be between the marks «MIN» And «MAX» on the dipstick (pic. 7.15).
3. Add steering fluid if necessary (Mercedes-Benz 000 969 88 03). Use only new fluid, as even minimal contamination can lead to hydraulic failure.
4. Reinstall the dipstick plug and tighten it.
5. Finally, bleed the air from the power steering system by turning the steering wheel from lock to lock several times with the engine running.
