WARNING
Service product can be poisonous and haz-
ardous to health. There is a risk of injury.
Observe the instructions on the respective
original container when using, storing and dis-
posing off service products. Always store ser-
vice products in the sealed original container.
Always keep service products out of the reach
of children.
Coolant contains glycol and is therefore poison-
ous. Also observe the safety notes in the "Ser-
vice products and capacities" section
Y
( page 344).

WARNING
The engine cooling system is under pressure,
particularly if the engine is warm. You could
be scalded by hot coolant spraying out when
opening the cap. There is a danger of injury.
Allow the engine to cool before opening the
cap. Wear gloves and protective eyewear
when opening. Slowly turn the cap half a turn
to allow pressure to escape.
Only check the coolant level and/or fill the cool-
ant if the vehicle is on a level surface and the
engine has cooled down. The coolant tempera-
ture must be below 50 †.
! Check the engine cooling and heating sys-
tem regularly for leaks.
If a large quantity of coolant is lost, have the
cause traced and rectified at a qualified spe-
cialist workshop.
G
WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clean the antifreeze from components before
starting the engine.
! Take care not to spill any coolant on painted
surfaces. You could otherwise damage the
paintwork.
Example: cap and coolant expansion tank

X
Slowly turn cap : half a turn anti-clockwise
to allow excess pressure to escape.
X
Turn cap : further and remove it from cool-
ant expansion tank ;.
X
Check the coolant level.
If the coolant is up to marker bar = in the
filler neck when cold, there is a sufficient
amount of coolant in coolant expansion
tank ;.
If the coolant is approximately 1.5 cm above
marker bar = in the filler neck when warm,
there is a sufficient amount of coolant in cool-
ant expansion tank ;.
Topping up the coolant
X
If the coolant drops under marker bar = in
the filler neck, top up the coolant.
Observe the information on the correct cool-
ant mixture ratio and the required water qual-
ity under "Service products and capacities"
Y
( page 350). To prevent damage to the
engine cooling system, use only approved
corrosion inhibitor/antifreeze that complies
