Attention! Use only coolant concentrates approved for Mercedes vehicles.
Since the anti-corrosion component in the coolant loses its effectiveness after some time, the coolant must be replaced every 3 years.
Attention! If the antifreeze content in the coolant exceeds 55% (corresponds to protection down to -45°C), frost protection is reduced and heat dissipation by the cooling system is impaired.
