Diesel engines MB-Freigabe or MB-
CLS300 d
All other models
* recommended for lowest possible fuel con‐
sumption (lowest SAE viscosity class in each
case; observe possible restrictions of the
approved SAE viscosity classes)
To achieve the lowest possible fuel consumption,
it is recommended to use the engine oil specifi‐
cations marked in the table for the lowest SAE
viscosity class. Possible restrictions of the
approved SAE viscosity classes must be
observed.
% If the engine oils listed in the table are not
available, you may add a maximum of
1.0 litre of the following engine oils once
only.

Notes on brake fluid
Observe the notes on operating fluids
( page 347).
/
& WARNING Risk of an accident due to
vapour pockets forming in the brake sys‐
tem
The brake fluid constantly absorbs moisture
Capacity
from the air. This lowers the boiling point of
the brake fluid. If the boiling point is too low,
6.8 litres
vapour pockets may form in the brake sys‐
tem when the brakes are applied hard.
This impairs the braking effect.
6.6 litres
Have the brake fluid renewed at the
#
specified intervals.
