Checking Fluid Level For Power-Assisted Steering

CAUTION: Increased risk of accidents and material damage if too much Pentosin CHF 202 is filled in or if Pentosin CHF 202 comes into contact with the coolant hoses when filling or topping up.

It is possible to overfill the system, causing Pentosin CHF 202 to overflow onto coolant hoses and other components.

→ Start and run the engine for about 20 seconds prior to the fluid level check. Multiple steering operations (manoeuvring) will change the fluid level in the reservoir. Check the fluid level.

→ If coolant hoses come into contact with Pentosin, clean them thoroughly with water IMMEDIATELY.

→ Replace visibly swollen coolant hoses.

Information

The reservoir is located at the front left of the engine compartment.

A dipstick with MAX/MIN markings is mounted on the cap of the reservoir. They are for a fluid level with a cold engine (approx. 20°C).
The MAX marking can easily be exceeded at higher temperatures.

Check the fluid level (Pentosin CHF 11 S) when the engine is stopped and cold (approx. 20°C).

The fluid level must be between the MAX and MIN marks. → Fig 2.

Start engine and run it at idle speed for approx. 20 seconds. Switch off engine.
Open engine cover and the lid of the engine compartment cover.
Open reservoir cap.
Wipe dipstick. Close and then reopen cap. The fluid level must be in the indicated range (MAX/MIN level at approx. 20 °C). Top up with Pentosin if necessary.
