WARNING Risk offire and explosion due
to fuel igniting
If yo u heat fuel sy stem components, e.g. with
a heat gun or open flame, these components
could be damaged.
Fu el may leak out and ignite. Depending on
th e type of damage, fuel might not escape
until the engine is running. #
Never heat fuel sy stem components. #
Consult a qualified specialist workshop
to have the malfunction rectified. Re
fill only with commercially available ULTRA-
LO W SULFUR DIESEL (ULSD, maximum sulfur
content 15ppm), which fulfills the ASTM D9 75
st andard.
The flow properties of diesel fuel may be inade‐
qu ate at low outside temp eratures due toparaf fin
separation.

resulting from paraf fin separa‐

To prev ent malfunctions, diesel fuel with

The benefits of high-quality engine oils are
re

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

WARNING Risk of an accident due to

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. #
