Wipe off dipstick. Close and then re-open cap. The fluid level should be between the MIN and MAX markings.
Top up with Pentosin if necessary.
- Do not add too much Pentosin!
- If assembly work was performed previously, check the fluid level with the engine idling and without operating the steering.
- Multiple steering movements (maneuvering) with the engine switched off change the fluid level in the reservoir - fluid level rises. In this case, the engine must be left running for at least 20 seconds immediately before checking the fluid level.
- When topping up or filling in Pentosin, make sure that it does not come into contact with the coolant hoses.
Close the cap carefully.
