& WARNING ‑ Risk of fire and injury from
antifreeze
If antifreeze comes into contact with hot
component parts in the engine compart‐

#
next to the filler opening.
Thoroughly clean off any antifreeze
#
from component parts before starting
the vehicle.

* NOTE Overheating at high outside tem‐
peratures
If an inappropriate coolant is used, the
engine cooling system is not sufficiently pro‐

#
Mercedes-Benz.
Observe the instructions in the
#
Mercedes-Benz Specifications for Oper‐
ating Fluids 310.1.
Have the coolant regularly replaced at a qualified
specialist workshop.
