Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli-
mate conditions. This is especially impor-
tant if you live in a region where the win-
ter is extremely cold. If necessary, in-
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad-
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au-
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor-
rosion protection . The resulting corro-
sion can cause a loss of coolant and se-
rious engine damage.
- Do not add any type of radiator leak seal-
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse-
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.

.,. Read the engine coolant level in the open
coolant expansion tank. With a cold engine,
the coolant level should be between the
"min " and "max" markings. When the en-
gine is warm, the level may be slightly above
the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus-

To obtain an accurate reading, the engine
must be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System ¢ page 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec-
ommend you check the coolant level from
time to time .
