— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-

When you no longer see or hear steam or
coolant escaping, you may open the engine

remember that the radiator fan can switch

coolant in the original container and away
from children. There is a risk of poisoning.

Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.
