Topping up the coolant

G
WARNING
The cooling system is pressurised, partic-
ularly when the engine is warm. If you
open the cap, you could be scalded if hot
coolant sprays out. There is a risk of injury.
Let the engine cool down before you open
the cap. Wear gloves and eye protection.
Open the cap slowly to release the pres-
sure.
!
Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Internet
at http://bevo.mercedes-benz.com. Or
contact a qualified specialist workshop.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point
of the coolant during operation is approx-
imately 130 †.
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should
be between 40% and 50% (antifreeze protec-
tion down to -37 †). This will protect the
engine cooling system against freezing down
to approximately -25 †.

steering and braking characteristics of the
vehicle. There is a risk of an accident.
Do not drive with a flat tyre. Immediately
