WARNING Risk of fire‑ and injury from antifreeze
If antifreeze comes into contact with hot component parts in the engine compartment, it may ignite.
Allow the engine to cool down before you top up the antifreeze.
Make sure that no antifreeze spills out next to the filler opening.
Thoroughly clean the antifreeze from component parts before starting the vehicle.
NOTE Damage caused by incorrect coolant
Only add coolant that has been premixed with the required antifreeze protection.
Information on coolant is available at the following locations:
in the Mercedes-Benz Specification for Operating Fluids 310.1
in the Mercedes-Benz BeVo app
at a qualified specialist workshop
NOTE Overheating at high outside temperatures
If an inappropriate coolant is used, the engine cooling system is not sufficiently protected against overheating and corrosion at high outside temperatures.
Always use coolant approved by Mercedes-Benz .
Observe the instructions in the Mercedes-Benz Specifications for Operating Fluids 310.1.
NOTE Paintwork damage due to coolant
Do not spill coolant on painted surfaces.
Have the coolant regularly replaced at a qualified specialist workshop.
Note the proportion of anti-corrosion agent/antifreeze in the engine cooling system within the following temperature ranges:
at least 50% (antifreeze protection up to about -37°C)
maximum 55% (antifreeze protection up to -45°C)
