1 Coolant reservoir cap
2 Marking for coolant level
Checking Coolant Level
The coolant level can be checked
visually at the transparent coolant
reservoir.
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. 1.5 cm (0.6 in) higher when
the engine is at operating tem pe­
rature.
Adding Coolant
If coolant has to be added, a 50/50
mixture of water and MB anticorrosion/
antifreeze should be used.
W arning!
• Use extreme caution when
opening the hood, if 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 be­
fore removing cap. The coolant
reservoir contains hot fluid and
is under pressure.
• Using a rag, turn cap to first
notch to relieve excess pres­
sure. If opened immediately, hot
scalding fluid and steam will be
blown out under pressure.
The drain plugs for the cooling system
are located on the right-hand side of
the engine block and the bottom of the
radiator.
