TIPS AND ADVICE
The correct coolant level is important for
proper functioning of the cooling system.
Therefore, check the coolant level regularly
- preferably at every fuel filling when you
check the oil.
To obtain an accurate reading, the engine
must be switched off.
Since the expansion tank is transparent, the
cap need not be removed to check t he coo-
lant level.
The coolant level must be between the
"MIN " and "MAX " marks when the engi-
ne is cold and can be slightly above the
"MAX" mark if the engine is wa rm.
The expansion tank in your vehicle is equip-
ped with an electric coolant level checking
device.
When the coolant level is too low, the war-
ning light (see "Warning
I
Indicator lights,"
chapter " INSTRUMENT PANEL AND CON-
TROLS" see Booklet 3.
1.) will blink until
the coolant level has been restored to nor-
mal.
Coolant losses
Coolan t losses may indicate a leak in the
cooling system. In t he event of coolant los-
ses, the cooli ng system should be inspec-
ted immediately by your authorized VOLKS-
WAGEN dealer. It is not enough merely to
add coolant.
In a sealed system, losses can occur only if
the boiling point of the coolant is exceeded
as a result of overheating.
