WARNING Risk of an accident due to

#

* 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.

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.

Mercedes-Benz recommends that you have the

oil change carried out at a qualified specialist

workshop.
