Caution
•
Other coolant additives may cause operational problems which, in partic-
ular, involves significantly redu
cing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss of
coolant and, as a consequence of th
is, result in major engine damage.
Inspecting the coolant levelThe coolant expansion bott
le 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
⇒
fig. 204
.
The coolant level when the engine is cold must lie between the (MIN) and (MAX) markings. The level may also rise slightly above 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
⇒page 38. We nevertheless recommend inspecting
the coolant level directly at the reservoir from time to time.
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 leak
s 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
⇒
.
– Top up the coolant. – Screw the cap tight until it is heard to lock.The coolant which you use for replenishi
ng 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

system with water and as soon as possible
arrange adjustment to correct the mixing
ratio of water and coolant additive again by a specialist garage. Only use fresh coolant for topping up the system.Do not fill up over the “MAX” marking! Exce
ss coolant which is heated up is forced
out of the cooling system through the pressure relief valve in the cap of the coolant compensation bottle. Wait until the engine has cooled down for a system which has suffered a major loss of coolant before pouring in coolant. Th
is is necessary to
avoid engine damage.
WARNING
•
The cooling system is pressurized! Do not open the cap of the coolant
expansion bottle if the engine is still hot - risk of scalding!•
The coolant additive and thus all of the coolant is harmful to your health.
Avoid contact with the coolant. Coolant vapours are also harmful to the health. It is important, therefore, to always safely store any coolant additive in its original container out of the reach of children - risk of poisoning!•
If any splashes of coolant get into yo
ur eyes, rinse out your eyes immedi-
ately with clear water and contact
a doctor as soon as possible.
•
You should also consult a doctor without delay if you have inadvertently
swallowed coolant.
Caution
Do not continue your journey if for some reason it is not possible under the conditions prevailing to top up with coolant. Switch of the engine and contact
and obtain professional assistan
ce from a specialist garage.
For the sake of the environment
Do not re-use coolant if it is necessary to
drain the coolant in the system. It should
be collected and disposed of in comp
liance with environmental protection
regulations.
Radiator fan The radiator fan may switch on suddenly.The radiator fan is driven by an electric motor and controlled according to the coolant temperature. The radiator fan may continue running for
up to 10 minutes after the engine has
been switched off - even if the ignition is
also off. It may al
so switch on suddenly
after a certain time, if•
the coolant temperature has risen because of an accumulation of heat or
•
the warm engine compartment is heated
up additionally by strong sunlight.
WARNING
You must therefore be aware when work
ing in the engine compartment that
the fan may switch on suddenly - risk of injury!Brake fluidInspecting the brake fluid level
