If coolant has to be added, a 50/50 mixture of water and
MB anticorrosion / antifreeze should be added.Windshield and headlamp washer system
1Windshield 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).
Wa r n i n g !
• 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.
