Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly reducing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of this, result in major engine damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on
the right.
– Switch the engine off.
– Open the bonnet ⇒ page 223, "Working in the engine compartment".
– Check the level of coolant in the coolant expansion bottle
The coolant level when the engine is cold must lie between the
A
a
(MIN) and (MAX) markings. The level may also rise slightly above
A
a
the (MAX) marking when the engine is warm.
If the coolant level in the reservoir is too low, this is indicated by the warning light

in the instrument cluster
the coolant level directly at the reservoir from time to time.

Driving Tips
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the system. You
should not merely top up the coolant in the reservoir. It is also important to have
the cooling system inspected without delay by a specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant expan-
sion bottle which is completely free of leaks if the coolant boils as a result of over-
heating and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒ page 223, "Working in the engine
compartment" before working in the engine compartment.
Caution
One should contact a specialist garage as soon as possible if the source of over-
heating itself cannot be determined and removed, since there may be grave
damage to the engine.
Replenishing the coolant
– Switch the engine off.
– Allow the engine to cool down.
– Place a cloth over the cap of the coolant expansion reservoir
⇒ fig. 204
and unscrew the cap carefully by turning it to the left

b – Top up the coolant.
– Screw the cap tight until it is heard to lock.
The coolant which you use for replenishing the system, must comply with one
specific specification ⇒ page 226, "Coolant". Do not use an alternative additive if
the coolant additive G12 PLUS is not available in exceptional cases. Just top up the
