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:

The coolant must remain in the cooling
system all year round for corrosion protection
purposes and to increase the boiling point –
even in countries with hot climates.
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
inhibitors that comply with the MB
Specification for Service Products, Sheet
No. 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 being renewed, the
coolant must contain 50 % by volume of
anticorrosion/antifreeze agent. This provides
antifreeze protection down to
–34.6 ‡(–37 †).
Do not exceed a proportion of
55 % by volume (antifreeze protection down
to approximately –49.0 ‡ (–45 †)),
otherwise heat dissipation is reduced.
If there is a loss of coolant, do not replenish
with water only, but also add an approved
corrosion inhibitor/antifreeze agent. 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 Number 325.
