Additives
!
Do not use additive sinengine oil .This
could damage the engine.
Engine oil viscosity Viscosit
ydescribes the flow characteristi cs
of afluid. If an engin eoil has ahigh viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SA Eclassification (viscosity). The table
below shows you which SA Eclassifications are to be used. The low-temperature proper-
ties of engin eoils can be significantly
impaired durin goperation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommende dtoobserve
regula roil changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid

WAR
NING
Over aperiod of time, the brak efluid absorbs
moisture fro mthe air ;This lower sits boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). Thi simpairs brakin geffi-
ciency.
Yo us hould hav ethe brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Servic eBooklet.
Only use brak efluid approved by Mercedes-
