CAUTION
■
Do not continue your journey if for some reason it is not possible to fill
with coolant under the current circumstances. Switch off the engine and seek
assistance from a specialist garage.
■
The concentration of coolant additive in the coolant must never be under
40%.
■
Over 60% of coolant additive in the coolant reduces the antifreeze protec-
tion and cooling effect.
■
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
A
» Fig. 153 on page 179.
■
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
The coolant capacity is approximately 1 l greater on vehicles that are fitted
with an auxiliary heater (auxiliary heating and ventilation).
Checking the coolant level

The coolant expansion bottle is located in the engine compartment.

Mark for the maximum permissible coolant level
Mark for the lowest permissible coolant level

B
The coolant level should be kept between the marks
A
and
B
.
The coolant can be checked and topped up, if the following conditions are sat-
isfied.
The vehicle is standing on a horizontal surface.
The engine is turned off.
The engine is not heated.
The bonnet is open.
Checking the level
›
Check the coolant level in the coolant expansion tank » Fig. 153.
If the engine is warm, the test result may be inaccurate. The level can also be
above the mark
A
» Fig. 153.
In case of low coolant level, in the instrument cluster a check mark
is shown
and the corresponding message » page 34. 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 cooling sys-
tem. Do not merely top up the coolant. Have the cooling system checked by a
specialist garage.
Replenishing
Read and observe and on page 178 first.
›
Place a cloth over the cap of the coolant expansion tank and unscrew the
cap carefully.
›
Replenish the coolant.
›
Turn the cap until it clicks into place.
CAUTION
■
Only top up with new coolant.
■
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.
