1 Coolant reservoir cap
2 Marking for coolant level
The coolant level can be checked vis­
ually at the transparent coolant reser­
voir.
To check the coolant level, the vehicle
must be parked on level ground.
The coolant level must reach:
The marking (2, arrow) on the reser­
voir when the engine is cold.
Approx. 2 cm (0.8 in) higher when the
engine is at operating temperature.
Adding Coolant
If coolant has to be added, a 50/50
mixture of water and MB anticorro­
sion/antifreeze should be used.
Checking Coolant Level
• Use extreme caution when open­
ing the hood, in case there are
any signs of steam or coolant
leaking from the cooling system.
• Do not remove pressure cap on
coolant reservoir if engine tem­
perature is above 90° C (194° F).
Allow engine to cool down
before removing cap. The cool­
ant reservoir contains hot
water/anticorrosion/antifreeze
mixture and is under pressure.
• Using a rag, turn cap to first
notch to relieve excess pressure.
If opened immediately, hot
scalding fluid and steam will be
blown out under pressure.
The drain plugs are located on the
right side of the engine and on the
radiator bottom.
