COOLING SYSTEM
Always heed WARNINGS on page 102.
113
The cooling system is sealed
rally requires little attention.
The cooling system has been filled at the
factory with a permanent coolant which
does not need to be changed. The cool-
ant consists of a mixture of water and the
manufacturer's coolant additive G11 –
antifreeze on glycol basis with anticorro-
sion additives (40% for USA models;
60% for Canadian models). This mixture
assures the necessary frost protection
and protects the entire cooling system
itive proportion
and gene-
against corrosion and scalding, and rai-
ses the boiling point of the coolant,
Do not reduce the concentration of the
coolant in the summer by adding plain
water.
The coolant add
must be at least 40% but not more
than 60%
, to maintain the antifreeze
protection and the cooling efficiency.
For year round driving, antifreeze is ad-
ded at the factory for temperatures down
to
-13 °F/ -25 °C (USA)
-40 °F/ -40 °C (Canada)
Only use quality phosphate-free antifre-
eze containing ethylene glycol. Such anti-
freeze is available at your Audi dealer.
WARNING
Antifreeze is poisonous! Always store
antifreeze in its original container and
well out of the reach of children. If you
drain the coolant, it must be caught
and safety reused. Dispose of it pro-
perly without endangering the envi-
ronment.
Checking the coolant level
The coolant level should be checked
from time to time, and always before go-
ing on a longer trip.
WARNING
To reduce the risk of being burned,
never open the hood if you see or
hear steam or coolant escaping from
the engine compartment. Wait until no
steam or coolant can be seen or heard
before carefully opening the hood.
, the coolant
level in the transparent expansion tank
should reach the MINIMUM filler mark
(arrow).
When the engine is warm , the coolant
level will rise slightly above the mark. The
expansion tan* is also equipped with an
electric coolant level checking device.
If the coolant level drops below the MINI-
MUM mark the coolant warning light will
come on. Refer to “Auto-Check System"
on page 54 for details.
Since the expansion tank is transparent,
the cap need not be removed to check
the coolant level.
