TEEngine damage due touse of addi‐
tives in the engine oil The use of additional additives in
the engine
oil can damage the engine. #
Do not use any additional additives in
the engine oil. Miscibility of engine oil
The benefits of high-quality engine oils are
re
duced bymixing oil.
We recommend that you on lyuse engine oil of
th e same grade and SAE classi fication as the oil
fi lled at the last oil change. If, in exceptional
cases, engine oil of the type in the engine is not
av ailable, use ano ther appr oved mineral or syn‐
th etic engine oil.
Ve hicles with a diesel engine: ifth e grade is
not available, you may also refill with engine oils
acco rding toMB-F reigabe or MB-Appr oval 228.5,
229.3 or 229.5. The refill qu antity is then limited
to maximum 1.1 US qt (1.0 liter).
Yo u must then ha vean oil change car ried out at
th e earliest possible opportunit y.
Ve hicles with a gasoline engine: ifth e grade is
not available, you may refill with engine oils
acco rding toMB-F reigabe or MB-Appr oval 229.3
or AC EA A3/B4. The refill qu antity is then limited
to maximum 1.1 US qt (1.0 liter).
Yo u must then ha vean oil change car ried out at

Engine oils are di fferentiated according to:
R Engine oil brand
R Grade (MB-F reigabe or MB-Appr oval)
R SAE classi fication (viscosity)

The on-board computer automatically sho ws the

ption
Depending on the driving style, theve hicle con‐
sumes a maximum of 1.1 US qt (1.0 liter) of
engine oil per 620 miles (1000 km).
In thefo llowing cases, oil consum ption may also
exc eed this limit:
R The vehicle is ne w.
R You use theve hicle mostly under arduous
conditions.
R You drive frequent lyat a high engine speed.
Re gular maintenance is a prerequisite forfa vo ra‐
ble consum ption figures. You can only assess the
oil consum ption af ter a long journe y.Check the
oil le vel in the engine regularly, e.g. weekly or
eve rytime youre fuel. Note

WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
tem
The brake fluid con stant lyabsorbs moisture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be impaired. #
Have the brake fluid rene we d at the
