216Checking and refilling levels
Topping up coolant
Top up coolant when the level is below the MIN (minimum)
mark.
Fig. 110 Engine com-
partment: Coolant expan-
sion tank cap
Checking coolant level
– Park the vehicle in a horizontal position.
– Switch the ignition off
– Read off the coolant level on coolant expansion tank. When the
engine is cold, the coolant level should be between the marks.
When the engine is hot, it may be slightly above the upper
mark.
Topping up coolant
– Wait for the engine to cool down.
– Cover the coolant expansion tank cap with a cloth and carefully
unscrew it to the left ⇒ 
. –
Top up the coolant only if there is still coolant in the expansion
tank, otherwise you could damage the engine. If there is no
coolant in the expansion tank, do not continue driving. You
should obtain professional assistance ⇒ 
.
– If there is still some coolant in the expansion tank, top up to the
upper mark.
– Top up with coolant to the upper mark until the level becomes
stable.
– Screw the cap back on correctly.
Any loss of coolant fluid normally indicates a leak in the cooling system.
Take the vehicle straight to a specialised workshop to have the cooling sys-
tem examined. If there are no leaks in the engine cooling system, a loss of
coolant can only occur if the coolant boils and is forced out of the system as
a result of overheating.
WARNING
● The cooling system is under pressure. Do not unscrew the cap on the
coolant expansion tank when the engine is hot: risk of burns!
● The antifreeze and coolant fluid can be a health hazard. Therefore,
the antifreeze should be stored in the original container in a safe place
out of reach of children. Failure to comply could result in poisoning.
● If working inside the engine compartment, remember that, even when
the ignition is switched off, the radiator fan may start up automatically,
and therefore there is a risk of injury.
CAUTION
Do not top up the expansion tank with coolant fluid if it is empty! Air could
enter the cooling system. In this case, stop driving. Seek specialist assis-
tance. Otherwise, there is a risk of engine damage. 
