tives
Do not use engine oils or oil filters other
#
than those which meet the specifica‐
tions necessary for the prescribed
service intervals.
Do not alter the engine oil or oil filter in
#
order to achieve longer change intervals
than prescribed.
Do not use additives.
#
Have the engine oil changed after the
#
prescribed intervals.
Mercedes-Benz recommends that you have the
oil change carried out at a qualified specialist
workshop.

Notes on brake fluid
Observe the notes on operating fluids
( page 496).
/
& WARNING Risk of an accident due to
vapor 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,
vapor pockets may form in the brake system
when the brakes are applied hard.
This causes the braking effect to be
impaired.
Have the brake fluid renewed at the
#
specified intervals.
