CAUTION
If for some reason it is not possible to top up the coolant under the current
■
circumstances, do not continue driving! Switch off the engine and seek as-

sistance from a specialist garage.
If the expansion tank is empty, do not top up with coolant. The system could
■
aerate - risk of engine damage,

gine and seek assistance from a specialist garage.
The amount of coolant additive in the coolant must never be allowed to be
■
less than 40 %.
Over 60 % of coolant additive in the coolant reduces the antifreeze protec-
■
tion and coolant effectiveness.
A coolant additive that does not comply with the correct specification can
■
significantly reduce the corrosion protection of the cooling system.
Any faults resulting from corrosion may cause a loss of coolant and can con-
■
sequently result in major engine damage.
Do not fill the coolant above the mark
■
If an error occurs, leading to the engine overheating, the help of a professio-
■
nal garage is to be sought - there is a risk of serious engine damage occurring.
Additional headlights and other attached components in front of the air inlet
■
impair the cooling efficiency of the coolant.
Never cover the radiator - there is a risk of the engine overheating.
■
Note
On vehicles that are fitted with an auxiliary heater (auxiliary heating and venti-
lation), the coolant capacity is approx. 1 l larger.

Checking the level
›
Check the coolant level in the coolant expansion tank
If the engine is warm, the test result may be inaccurate. The level can also be
above the mark » Fig. 200.
A
In the event of an insufficient coolant level, the control symbol  is displayed
in the instrument cluster as well as the relevant notification
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 cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing

Read and observe and
The coolant expansion tank must always contain a small amount of coolant
» page 195, in section Introduction.
›
Place a cloth over the cap of the coolant expansion reservoir and unscrew
the cap carefully.
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
Do not use an alternative additive if the specified coolant is not available. In
this case, use just water and have the correct mixing ratio of water and cool-
ant additive restored by a specialist garage as soon as possible.
