Read and follow the WARNINGS before check­
ing anything
in the engine compartment
Qpage236.
Checking the engine coolant level
""Park your vehicle on a level surface.
"" switch the ignition off.
.. Read the coolant level on the coolant expansion
tank
Q page 238, fig. 184. The coolant level
must be between the markings when the en­
gine
in cold. When the engine is warm it can be
slightly above
the upper marking.
Adding coolant
Requirement: there must be a res idual amount of
coo l
ant in the expans io n tank c:?(i) .
""Let the engine cool down.
.. Place a cloth over the coolant expansion tank
cap and unscrew
the cap counterclockwise
c:?,8..
""Add coolant mixed in the correct ratio
i:?page 242 up to the upper marking.
""Make sure that the fluid level remains stable.
Add more coolant if necessary.
"" Close the cap securely .
A coolant loss suggests a leak. Immediately drive
your vehicle
to an authorized Audi dealer or au­
thorized
Audi Service Facility and have the cool­
ing system inspected.
If the cooling system is not
leaking, a loss can come from
the coolant boiling
through overheating and being pushed
out of the
cooling system.
.&. WARNING
-The cooling system is pressurized and can be-
come very hot.
To reduce the risk of burns
from hot coolant:
-
Do not open the coolant expansion tank cap
w ith
the engine hot. There is a risk of burns .
- Stop
the engine and allow it to cool.
-
Protect your face, hands and arms from es-
caping coolant and
steam by covering the
coolant tank cap with a large, thick cloth.
- Turn
the coolant tank cap counterclockwise
slowly and keep light pressure on
the cap.
-
To reduce the risk of burns, do not allow any
antifreeze or coolant to dr
ip onto the ex-
Checking and Filling
ha ust system or hot engine components.
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health.
For this reason,
keep
the coolant in the original container
away from children. There is a
risk of poi­
soning.
-When working in the engine compartment,
remember
that the radiator fan can switch
on even if
the ignition is switched off, which
increases
the risk of personal injury.
CD Note
Do not add coolant if the expans ion tank is
empty . Air could enter the cooling system and
damage
the eng ine. If this is the case, do not
continu e driving. See an authorized
Audi dea l­
er or authorized
Audi Service Facility for assis­
tance.
Radiator fan
The radiator fan switches on automatically by it­
self.
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch
the engine off, the auxiliary fan
can continue running for
up to 10 minutes -even
with
the ignit ion off. It can even switch on again
later by itself c:? & . if
- the temperature of
the engine coolant rises due
to
the heat build-up from the engine in the en­
gine compartment, or
-
the engi ne compartment heats up because the
vehicle is parked in intense sunlight.
.&. WARNING
-To reduce the risk of personal injury never
touch
the radiator fan.
- The auxiliary electric fan
is temperature
controlled and can switch on suddenly even
when
the engine is not running.
