Changing th e engine oil
The eng ine oi l and oil fi lter m ust be changed
according to the mileage (kilometers) and
t ime intervals specified in your veh icle's War ­
ranty
& Maintenance booklet. Do not exceed
these interva ls - harmful deposits from old
engine oil ca n reduce engine performance and
can lead to expensive e ngine repa irs.
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­
ing propert ies of oil decrease gradually during
normal veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
should even be changed more frequent ly .
Change oil more often if you drive most ly
sho rt distances, operate the ve hicl e in dusty
areas o r most ly unde r stop-and-go traff ic con­
ditions, or when you use your vehi cle where
temperatures stay be low freezing point for
long pe riods .
Detergent addi tives in the oil will make fresh
o il look dark after the engine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often t han
recommended.

-The oil filler cap must be properly se­
cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running - fire hazard!
-If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
@ Note
-Check the oil level. If the message
Please reduce oil level appears, contact
your authorized Audi dealer or other qualified workshop to have excess oil ex ­
tracted if necessary .
-Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
-Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com ­
partment,
always read and heed all WARN­
INGS
~ .&. in Working in the engine compart­
ment on page 228.
T he engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet . This is very important
because the lubricating properties of oil di­
minish gradually during normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con­
ditions , or have your vehicle where tempera-
Checking and filling 235
tu res remain below freezing for extended pe­
riods.
Detergent additives in the oil will make fresh
oil look dark after the engine has been run­ ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex­
pertise requir ed, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choose to change your oil yourself,
please note the following important informa­
tion:
_& WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to hold at least the total amount of oil in
your engine .
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil
off thoroughly
with soap and water.
(D Note
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 .

236 Check ing and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used oil.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, 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 .
Engine 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
qu ires little attention .
The cooling system has been filled at the fac ­
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly conditioned water and the
manufacturer 's glycol-based coo lant add i-
tive G l3 antifreeze with ant icorrosion addi ­
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es­
sary frost protection and protects metal com­ ponents in the engine's cooling sys tem from
corrosion and scaling . It a lso raises the boil­
ing point of the coolant .
Do not red uce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add it ive mu st be at
l e a st 50 % but not more than 60 %
to main­
tain antifreeze protection and cooling efficien­
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld freeze and damage the veh i­
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa ­
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 228.
(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 conditions . This is especia lly impor­
tant if you live in a reg ion where the win­
ter is ex treme ly cold. If ne cessa ry, i n­
crease the pr opo rtion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c ooling sys tem, remembe r:
- We recommend using on ly coolant ad ­
d itive Gl2++ or Gl3 for your vehicle .
This coolant additive is availab le at au­
thor ized Audi dealers . Other types of
ant ifreeze can s ignificant ly reduce cor­
rosion protection. The resulti ng cor ro­
sion can ca use a loss o f coolan t and se­
rio us engine damage.
- Do not add any type of rad iator leak seal­
a nt to yo ur vehicle 's engine coolant.
Add ing radiator repai r fl ui d may adverse ­
ly affect the function and performance of
your cooling system and co uld resu lt in
damage not covered by yo ur New Vehicle
Limited Warranty.
