Engine oil SAE classification
Viscosity indicates the flow characteristics of a
fluid. If an engine oil has a high viscosity, this
means that it is thick; a low viscosity means that
it is thin.
Depending on the respective outside tempera-
tures, select an engine oil according to SAE
classification (viscosity). The table displays the
SAE classification to be used. The low temper-
ature characteristics of engine oils can notice-
ably deteriorate during operation, e.g. from age-
ing, soot and fuel accretion. For this reason,
regular oil changes using an approved engine oil
from the suitable SAE classification are urgently
recommended.
Oil change
Oil change intervals depend on the vehicle's
operating conditions and the quality of the
engine oil used. The on-board computer auto-
matically shows the date for the next oil change
as an event message in the display.
Mercedes-Benz recommends having the oil
changed at a qualified specialist workshop.
Information about oil consumption
Depending on the driving style, the vehicle con-
sumes a maximum of 1.0 l of engine oil every
1000 km.
Oil consumption may be higher if:
R
the vehicle is new
R
you mainly operate the vehicle under arduous
operating conditions
R
you frequently drive at high engine speeds
Regular maintenance is one of the preconditions
for moderate rates of consumption.
You can only estimate the oil consumption after
you have driven a considerable distance.
Check the engine oil level on a regular basis, e.g.
weekly or each time you refuel (

Brake fluid

WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak-
ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
!
Brake fluid corrodes paint, plastic and rub-
ber. If brake fluid comes into contact with
paint, plastic or rubber, rinse with water
immediately.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations
and the important safety notes for service prod-
ucts (
Y
page 379).
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified inter-
vals by a qualified specialist workshop.
i
There is usually a notice in the engine com-
partment to remind you when the next brake
fluid change is due.
Use only approved brake fluids that comply with
the Mercedes-Benz Specifications for Service
Products. Always check for the identification
DOT 4 plus.
