Notes on brakefluid
Observethe notes on operatingfluids(page 425).
\nWARNINGRisk of an accident duetovapor pocketsforming inthe brake sys‐tem
The brakefluid constantly absorbs moisturefromthe air. This lowersthe boiling point ofthe brakefluid. Ifthe boiling point istoo low,vapor pockets mayforminthe brake systemwhenthe brakes are applied hard.
This causesthe braking effecttobeimpaired.
Havethe brakefluidrenewed atthespecified intervals.
Havethe brakefluidregularlyreplaced at aqualified specialistworkshop.Only use brakefluid approvedbyMercedes-BenzaccordingtoMB-Freigabe or MB-Approval 331.0.
