Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Engine compartment Adding coolant If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added. Warning! • In order to avoid possibly serious burns: Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system, or if the coolant temperature gauge indicates that the coolant is overheated. • Do not remove pressure cap on coolant reservoir if engine temperature is above 194°F (90°C). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure. • Using a rag, slowly open cap approximately 1/2 turn to relieve excess pressure. If opened immediately, scalding hot fluid and steam will be blown out under pressure. • Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. 302 Windshield and headlamp washer system 1 Windshield and headlamp washer fluid reservoir The reservoir should be refilled with MB Windshield Washer Concentrate and water (or concentrate commercially available premixed windshield washer solvent/antifreeze, depending on ambient temperatures).
