engine oil.
Vehicles with a diesel engine: if the grade is
not available, you may also refill with engine oils
according to MB-Freigabe or MB-Approval 228.5,
229.3 or 229.5. The top-up quantity is then limi‐
ted to maximum 1.1 US qt (1.0 liter).
You must then have an oil change carried out at
the earliest possible opportunity.
Vehicles with a gasoline engine: if the grade is

Information on oil consumption
Depending on the driving style, the vehicle con‐
sumes a maximum of 1.1 US qt (1.0 liter) of
engine oil per 620 miles (1000 km).
In the following cases, oil consumption may also
exceed this limit:

Notes on brake fluid
Observe the notes on operating fluids
(

& 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.
* NOTE Damage to paint, plastic or rubber
by brake fluid
There is a risk of damage to property if brake
fluid comes into contact with paint, plastic or
rubber.
If paint, plastic or rubber comes into
#
contact with brake fluid, rinse with
water immediately.
Observe the notes on paintwork/matte finish
paintwork care (
page 273).
/
Have the brake fluid replaced regularly at a quali‐
fied specialist workshop.
Only use brake fluid approved by Mercedes-Benz
in accordance with MB-Freigabe or MB-Approval
331.0.
