A WARNING
- While top ping off, the oil must not come
in contact with hot engine pa rts - fire
hazard!
- The oil fille r cap must be prope rly se-
cured to preve nt oil from being sprayed
on the hot engine and exhaust system
when the eng ine is running - fire hazard!
- If your skin has come in contact with the
engine oil, yo u must subseque ntly
cleanse it t ho roughly.
(D Note
- The oil level must not be above range G)
- danger of conver t er or eng ine damage!
Contact an authorized Audi dea ler to
draw off oil, if necessa ry.
- Audi does not recommend the use of oil
additiv es. They may damage the engine
and adverse ly affec t your New Vehicle
Warr anty.
@) For the sake of the environment
- Under no circumstances ca n the oil come
in cont act wit h the sewage network o r
the soil.
- Observe and fo llow lega l regu lations
when d isposing of empty oil con ta ine rs.
Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter-
mines the freeze protection of the coolant in
the winter.
The cooling system is sea led and generally re-
q uires little attention.
The cooling system has been filled at t he fac-
tory with a permanent coolant which does not
need to be changed. The coolant consists of a
mixture of water and the man ufacture r's g ly-
col-based coolant additive Gl3 ant ifreeze
with a nt icorros ion add itives (50% for USA
models; 60% for Canad ian models). This mix-
ture bot h assures the necessary frost protec-
Checkin g and fillin g 175
t ion and protects meta l components in t he
engine's cooling system from corrosio n and
sca ling . It a lso raises the boiling point of the
coolant.
Do not reduce the concen t ration of the cool -
ant in the summer by adding plain wate r.
The
proportion of coolant additive must be at
least 50 % but not more than 60 %
to main-
ta in antifreeze protect io n and coo ling eff icien-
cy. If the coo la nt frost protection is too low,
t he coolant could freeze and damage the vehi-
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory fo r temperatures dow n to:
- - 31°F( - 35°C)USA
- - 40 °F ( - 40 °C) Canada .

(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli-
mate condit ions. This is especially impor-
tant if you live in a region where the win-
ter is extremely cold. If necessary, in-
crea se t he propo rtion of coo lant add itive
to 6 0 %.
- Whe n adding coolant addi t ive to your
coo ling syst em, reme mbe r:
- We recommend us ing on ly coo lant ad-
d itive Gl2 ++ or Gl3 (check the labe l)
for your vehicle. This coolant additive is
ava ilable at authorized Aud i dea lers .
Othe r ty pes of antifreeze ca n sig nifi-
cantly reduce cor ros io n protec t ion. The
resu lting corrosion can cause a loss of
coo lant a nd serio us e ng ine da mage.
- Do not add any type of rad iator leak seal-
ant to your vehicle's engi ne coo lant .
Add ing radia t o r repair f luid may adverse-
ly affect the function and pe rformance of .,..
