Risk of injury
When opening the coolant expansion tank
there is a risk of scalding from hot coolant
spraying out. The cooling system and the
coolant expansion tank are pressurised
when the engine is at normal operating tem-
perature. Wear gloves and eye protection.
Only open the coolant expansion tank when
the coolant temperature is less than 50 °C.

Risk of poisoning
Coolant contains glycol and is therefore
toxic. Do not swallow coolant. Consult a
doctor immediately if any coolant is swal-
lowed.
Coolant must not come into contact with
skin, eyes or clothing. If coolant has come
into contact with your eyes, wash them with
plenty of clean water. Clean skin and cloth-
ing immediately with soap and water.
Change out of contaminated clothing imme-
diately.
E Slowly unscrew cap 1 on the coolant
expansion tank about half a turn anti-
clockwise and allow excess pressure to
escape.
E Turn cap 1 further and remove it.
E Check the coolant level and top up if
necessary. Observe the required cool-
ant composition and water quality
when doing this (
e page 239).
The level of the coolant
I
must reach the max mark 2 when
the coolant is cold
I
and reach about 1.5 cm above the
max mark
2 when the coolant is
hot.
E Replace cap 1 and tighten all the way
to the stop.
! Check the cooling and heating systems
regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz Service
Centre.
