Coolant additive with corrosion and
antifreeze protection
The coolant is a mixture of water and antifreeze
and corrosion inhibitor. It performs the following
tasks:
R
corrosion protection
R
antifreeze protection
R
raising the boiling point
When the vehicle is first delivered, it is filled with
a coolant mixture that ensures adequate anti-
freeze and corrosion protection. Coolant must
remain in the engine cooling system all year
round to ensure corrosion protection and a
higher boiling point – even in countries with high
outside temperatures.
Mercedes-Benz recommends an antifreeze and
corrosion inhibitor that meets the requirements
in the Mercedes-Benz Specifications for Service
Products Sheet Number 325.5.
Information about antifreeze and corrosion
inhibitors approved by Mercedes-Benz is avail-
able:
R
from any Mercedes Benz Service Centre
R
on the Internet at
http://bevo.mercedes-benz.com under the
specifications on Sheet No. 325.5
Check the corrosion inhibitor/antifreeze con-
centration in the coolant every six months.
The percentage of antifreeze and corrosion
inhibitor in the engine cooling system should:
R
be at least 50%. This way, the engine cooling
system is protected against freezing down to
approximately -37 †.
R
not exceed 55% (antifreeze protection down
to -45 †). Otherwise, heat will not be dissi-
pated as effectively.
If there has been coolant loss, do not refill only
with water. If the vehicle has lost coolant, top up
with equal parts water and antifreeze and cor-
rosion inhibitor. The water used as part of the
coolant mixture must fulfil certain require-
ments; these are usually fulfilled by drinking
water. If the water quality is not sufficient, you
must treat the water.
Further information may be obtained at any
qualified specialist workshop.
Maintenance interval
Have the coolant replaced at specified intervals
by a qualified specialist workshop.

WARNING
If windscreen washer concentrate comes into
contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with the filler
neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
When handling washer fluid, observe the impor-
tant safety notes on service products
(
Y
page 386).
Mixing ratio
Add windscreen washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the outside temperatures.
At temperatures above freezing:
X
Top up the washer fluid reservoir with a mix-
ture of water and windscreen washer concen-
trate, e.g. Summerwash to prevent smearing.
At temperatures below freezing:
X
Top up the washer fluid reservoir with a mix-
ture of water and windscreen washer concen-
