Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oi l into a conta iner designed
for this p urpose, one large eno ugh to
hold at least the total amount of oil in
your engi ne.
- Engine oil is poisono us. Keep it well out
of the reach of c hildren .
- Cont inuo us contact with used engine oil
is harmful to your skin. Always protect
you r sk in by washing oil off thoroug hly
with soap and water .
(D Note
Never mix oil addit ives with your engine
oil. These additives can damage your en­
gine and adversely affect y our Aud i Limit­
ed New Vehicle Wa rra nty .
@ For the sake of the environment
- Before changing your oi l, f irst make sure
you know whe re you can proper ly dispose
of the used o il.
- Always d ispose of used engine oil proper­

ed a reas, into open streams or down
sewage dra ins.
- Recycle used engine o il by taking it to a
u se d engine oil collection facility in your
a rea, or contact a servi ce station .
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sea led an d generally re ­
q uir es little attention.
The cooling system has been filled at the f ac­
tory with a pe rm anen t coo lan t which does no t
n eed to be changed. The coolant consists of a
mixture of specia lly conditioned water and the
manufacturer's glyco l-based coo lant add i-
tive Gl3 antifree ze with ant icorros ion addi-
Checking and Fillin g 225
tives (50% for USA mode ls; 60% fo r Canadian
models) . This mixture both ass ures the neces­
sary frost protection and protects metal com ­
ponents in the eng ine's cooling system from
corros io n and scaling. It also raises the bo il­
ing point of the coolant .
Do not reduce the concentration of the cool ­
ant in the s ummer by adding p lain water.
The
proportion of coolant additive must be at
least 50°/o but not more than 60 %
to main­
ta in antifreeze protect io n and cool ing eff ic ien­
cy . If the coo lant frost p rotection is too low ,
t he coo lan t could freeze and damage the vehi ­
cl e heating and engine cooling sys tem.
Fo r year- round drivi ng, a ntifreeze is added at
the factory fo r temperatures down to:
- -31 °F
< -3s0c) u sA
- -40°F ( - 40°C) Canada.
If you must ad d coo lant, use a mixture o f wa ­
te r and coolant additive. Mixing the coo lant
additive with dist illed water is recommended.
A WARNING
Before you chec k anything in the engine
compartment, always read and heed all

(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
t ant if you l ive i n a region where the win-
t er is extremely cold. If necessary, in-
c rea se t he p ropo rtion of coo lant add itive
t o 6 0% .
- Whe n ad d ing coolant addi tiv e to yo ur
c ooling sys te m , reme mbe r:
- We recommend using on ly coo lant ad­
d itive Gl2 ++ or Gl3 (check the labe l)
for your vehicle. This coolant additive is ava ila ble at autho rized Aud i dea le rs .
Othe r ty pes of antifreeze ca n sig nifi­
cantly reduce cor ros io n protec tion . The
