COOLING SYSTEM, CHECKING THE COOLANT LEVEL, TOPPING OFF
COOLANT
• A wrong water/coolant mixing ratio will damage the radia-
tor!
Always mix water and coolant in the ratio 50:50. This also
applies to countries with a hot climate.
• Danger of fire! Coolant may be ignited by a hot engine!
Do not top off coolant, unless the engine has cooled down
sufficiently.
1. Open the engine hood.
2. Check whether the coolant level in the expansion tank is be-
tween the FULL and LOW markings.
If the coolant level does not reach up to the LOW marking,
top off coolant when the engine is cold.
3. Remove the cover cap of the overflow tank.
4. Top coolant until the level reaches up to the FULL marking.
5. After topping, firmly close the cover cap.
If the expansion tank is empty again after a short period of
time, immediately have the cooling system checked for leaks
and have any leaks repaired in the garage.
If the sub-tank must be topped, the coolant level in the cool-
er has to be checked.
