WARNING
Coolant contains glycol and is therefore toxic.
Do not swallow the coolant. See a doctor
immediately if you swallow coolant.
Make sure that coolant does not come into
contact with skin, eyes or clothing. In case of
contact with eyes, rinse immediately with
plenty of clean water. Clean affected areas of
skin and clothing with soap and water
immediately. Change any affected clothing
immediately.
Coolant is a mixture of water and antifreeze/
corrosion inhibitor.
In the coolant, the antifreeze/corrosion
inhibitor is responsible for:
R
corrosion protection
R
antifreeze protection
R
raising the boiling point
Coolant must remain in the engine cooling
system all year round to ensure anti-corrosion
protection and a higher boiling point, even in
countries with high outside temperatures.
At the factory, the vehicle is filled with a
coolant that ensures protection against frost
and corrosion and which can be mixed with
approved antifreeze/corrosion inhibitors.
!
Use only approved antifreeze/corrosion
inhibitor that complies with MB
Specification for Service Products, Sheet
Number 325. Using other, non-approved
antifreeze/corrosion inhibitors may cause
damage to the coolant system and reduce
the engine's service life.
Check the antifreeze/corrosion inhibitor
concentration in the coolant every six
months.
When the coolant is renewed, the coolant
must contain 50 % antifreeze/corrosion
inhibitor by volume. This provides antifreeze
protection down to Ò34.6 ‡ (Ò37 †).
Do not exceed a proportion of
55% by volume (antifreeze protection down to
approximately Ò49.0 ‡ (Ò45 †)). Otherwise
heat dissipation is reduced.
If there is a loss of coolant, do not replenish
with water only, but also add approved
antifreeze/corrosion inhibitor. The water in
the coolant must meet certain requirements,
which are often fulfilled by drinking water. If
the water quality is not sufficient, you must
treat the water.
Observe the MB Specifications for Service
Products, Sheet No. 325.

qualified specialist workshop.
