Never mix oil additives with your engine
oil. These additives can damage your en
gine and adversely affect your Audi Limit
ed New Vehicle Warranty.
@) For the sake of the environment
- Before changing your oi l, f irst make sure
you know where you can properly dispose of the used o il.
- Always dispose of used engine oil proper
l y. Do not dump it on garden so il, wood
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service 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 and generally re
q ui res little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -based coolant addi -
tive G l3 antifreeze with anticorrosion addi
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces
sary frost pro tection and protec ts metal com
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil
i ng po int of the coo lant .
Do not red uce the concentr ation of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficie n
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35°C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .

- Before wi nter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli
ma te conditions. This is especi ally impo r
tan t if you live in a reg ion where the win
ter is extreme ly cold . If necessary, in
crease the p roportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to yo ur
cooling system, remembe r:
- We recommend us ing on ly coola nt ad
d itive Gl2++ or Gl3 (check the labe l)
fo r your vehicle. This coolant additive is
a va ila ble at au thorize d Au di dea le rs.
Other types of antifreeze can sign ifi
ca ntly reduce corrosion p rotection. The
resu lting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak seal
ant to yo ur vehicle's engine coolant .
Add ing radiator repair f luid may adverse
ly affect the function and performance of
your cooling system and cou ld resu lt in
