Checking coolant level
Checking the coolant level (example)
XPark the vehicle on alevel surface. Only check the coolant level when the vehicle
is on alevel surface and the engine has cooled
down.
XTurn the SmartKey to position 2in the igni-
tion lock (Ypage 104).
XCheck the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡(70 †).
XSlowlyt urn cap :half aturn counter-clock-
wise and allow excess pressure to escape.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the fillern eck when cold, there is enough
coolant in coolant expansion tank ;.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar =in the fillern eck
when warm, there is enough coolant in cool-
ant expansion tank ;.
XIf necessary,add coolant that has been tested
and approved by Mercedes-Benz.
XReplace cap :and turn it clockwise as far as
it willg o.

Technical data

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protectthe engine
cooling system against freezin gdown to
approximately -35 ‡(-37 †).
Rnot exceed 55% (antifreez eprotection down
to -49 ‡[-45 †]). Otherwise, heat will not be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordanc ewith MB Spec-
ifications for ServiceP roducts 310.1.
iWhen the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
iThe coolant is checked at specified intervals
at aq ualified specialist workshop.
The engine cooling system is filled with coolant
at the factor ywhich contains antifreeze/corro-
sion inhibitor that ensures protection down to
approximately -35 ‡(-37 †).
