Inspecting the coolant level
The coolant expansion bottle is located in the engine compartment on the right.
Switch the engine off.
–
Open the bonnet ⇒ p age 180.
–
– Check the level of coolant in the coolant expansion bottle
ant level when the engine is cold must lie between the
markings. The level may also rise slightly above the
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 ⇒ p age 25, Coolant temperature/ Coolant quantity . We
still 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 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 ⇒ p age 181, Working in the engine com-
partment before working in the engine compartment.

Driving Tips
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 dam-
age 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
–
screw 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 replenishing the system, must comply with one
specific specification ⇒ p age 184. Do not use an alternative additive if the speci-
fied coolant additive 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 the coolant above the mark
and then is forced out of the cooling system through the pressure relief valve in
the cap.
Wait until the engine has cooled down for a system which has suffered a major
loss of coolant before pouring in coolant. This is necessary to avoid engine dam-
age.
WARNING
● The cooling system is pressurized! Do not open the cap of the coolant ex-
pansion 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!
