208 Inspecting and replenishing
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 expansion
bottle which is completely free of leaks if the coolant boils as a result of overheating
and is forced out of the cooling system.
WARNING
Read and observe the warning notes ⇒ page 204, "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 overheating
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
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 replenishing the system, must comply with one specific
specification ⇒ page 207. Do not use an alternative additive if the coolant additive
G12 PLUS - 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 top up the fluid above the hatched part! Excess 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. This 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 orig-
inal container out of the reach of children - risk of poisoning!
•
If any splashes of coolant get into your 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 the engine off and obtain
professional assistance from a specialist garage, otherwise it could lead to severe
engine damage.

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 compliance with environmental protection regulations.
