Notes on coolant
Observe the notes on operating fluids More.
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 use 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.
Have the coolant regularly replaced at a qualified specialist workshop.
Proportion of antifreeze concentrate in the engine cooling system:
a minimum of 50% (antifreeze protection down to approximately -37°C)
a maximum of 55% (antifreeze protection down to -45°C)
