The expansion tank in your vehicle is equipped
with an electric coolant level sensor
r::!) page 14.
We still recommend you check the coolant level
from time to time .
Coolant lo ss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cooling
system should be inspected immediately by your
author iz ed Audi dealer. It is not enough merely
to add coolant.
In a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
A WARNING
- The cooling system is under pressure. Do
not open the cap of the coolant expans ion
tank when the engine is hot. You risk being
sca lded.
-
- The coolant add itive, and therefore the cool­
ant itself, is hazardous to health. Keep the
c oolant additive in the or igina l co ntainer out
of the re ach of children.
It is a poison haz­
ard.
Ch eck ing and fillin g
(D Note
Do not add any type of radiator leak sea lant
to your vehicle's engine coolant . Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Veh icle Limited Warranty.

We recommend using only coolant add it ive Gl2+
+, G l3
or in an emergency Gl2 +. Do not use a
different additive. In an emergency use pla in wa­
ter unt il you ca n get the correct add itive and can
restore the co rrect ratio . This should be done as
soon as possib le .
If you have los t a considerab le amount of cool­
ant, then you shou ld add cold antifreeze and cold
water only when the engine is co ld .
Always use
new engine coo lant when refilling .
Do not fill coolant above the "max" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the eng ine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn off the engine and allow it to cool
down .
- Protect your face, hands and arms from escaping fluid and steam by covering the
cap with a large, thick rag.
163

Checking and filling
-Turn the cap slowly and very carefully in a
counter-clockwise direction while applying
light, downward pressure on the top of
the cap .
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi ­
tions, the ethylene glycol in engine cool­
ant can catch fire .
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison".
CD Note
-Coolant pollutes the environment and could
cause an engine fire . Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
-If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
¢ page 161 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after a peri­
od of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4".
164
Brake fluid is replaced according to the Audi
maintenance service schedule . Your authorized
Audi dealer is equipped with the necessary spe­
cial tools and replacement parts, has the neces­
sary expertise, and can dispose of the used fluid .
A WARNING
-Brake fluid is poisonous . It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­ priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
J 1703 and conforms to Federal
Motor Vehicle Standard
116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake fluid .
The correct type of brake fluid is also indi­ cated on the brake fluid reservoir.
- The brake fluid must be new . Heavy use of
the brakes can cause a vapor lock if the brake fluid is left in the system too long.
This can seriously affect the efficiency
of
the brakes as well as your safety . This
could result in an accident.
CD Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer.
