Checking coolant level
G WARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
! The coolant may only be checked and cor-
rected when the engine is cool (coolant
temperature below 104 ‡ (40 †). Check-
ing the coolant when the coolant tempera-
Engine compartment
ture is above 104 ‡ (40 †) may result in
damage to the engine or to the engine cool-
ing system.
Example
Park the vehicle on a level surface.
X
Only check the coolant level when the vehi-
cle is on a level surface and the engine has
cooled down.
Turn the SmartKey to position 2 in the igni-
X
tion lock ( page 141).
Y
Check the coolant temperature display in
X
the instrument cluster.
The coolant temperature must be below
104 ‡ (40 †).
Turn the SmartKey to position

0 ( page 141) in the ignition lock.
Y
Slowly turn cap : half a turn counter-
X
clockwise to allow excess pressure to
escape.
Turn cap : further counter-clockwise and
X
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.
If necessary, add coolant that has been tes-
X
ted and approved by Mercedes-Benz.
