Engine oil filling capacity (plug-in hybrid)
Model
B 250 e
The specified filling capacity refers to an oil
change with the oil filter.
Notes on brake fluid
Observe the notes on operating fluids
( page 404).
/
& WARNING Risk of an accident due to
vapour pockets forming in the brake sys-
tem
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point is too low,
vapour pockets may form in the brake system
when the brakes are applied hard.
This impairs the braking effect.
Have the brake fluid renewed at the
#
specified intervals.
Have the brake fluid regularly replaced at a quali-
fied specialist workshop.
Capacity
Only use a brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
5.1 litres

ponent parts in the engine compartment, it
may ignite.
Allow the engine to cool down before
#
you top up the antifreeze.
