-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.

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 204 Eng ine compartme nt: cover o n the coolant
expansion tank
Before you check anything in the engine com­
partment,
a lway s read and he ed all WARN ­
INGS ¢ & in Working in the engine compart­
ment on page 228.
Park your vehicle on a level surface.
~ Switch off the ignition.
~ Read the engine coolant leve l from the cool­
ant expansion tank¢
fig. 204, ¢ page 230.
With a cold engine, the coolant level should
be between the "min" and "max" markings.
When the engine is warm, the level may be sl ightly above the ''max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 230 .
To obtain an accurate reading, the engine
must be switched off.
The expansio n tank in your vehicle is equipped
with an electric coolant level sensor.
When t he coo lant level is too low, the warning
light in the Auto-Check System¢
page 15 will
illuminate unti l yo u add coolant and the level
has been restored to normal. Even thoug h
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool-
Checkin g and fillin g 237
ing system shou ld be inspected immediately
by your authorized Audi dealer . It is not
eno ugh merely to add coo lant .
In a
s ealed system, losses can occu r on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Red uce the risk of scald­
ing from hot coolant by follow ing these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id a nd steam by cover ing the
cap with a la rge, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
p lyi ng lig ht, dow nward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze o r coolan t on the exhaust system
or ho t engine parts. Und er certa in cond i­
tions, the ethylene gly co l in engine coo l­
an t can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coo lant. Add­
i ng radia to r repa ir flui d may adverse ly af­
fe ct the fun ct io n and perfor man ce o f you r
coo ling system and could result in damage
not cove red by your New Vehicle Limi ted
War ranty.
Adding coolant
Be very careful when adding engine coolant .
Before you che ck a nyt hing in the eng ine com­
partmen t,

- the temperature of the engine coolant rises
due to th e heat bui ld-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING
- To reduce the r isk of personal injury nev­
er touch the radiator fan.
- The auxiliary electr ic fan is temperature
controlled and can switch on sudden ly
even when the engine is not runn ing.
- The auxiliary radiator fan switches on au­ tomat ically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper ­
at ure drops.

Checkin g and fillin g 239
The fluid level may d rop slightly afte r some
time due to the automatic adjustment of the
brake pads . T his is not cause for alarm .
If the brake flu id leve l falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models) . (Canadian
models) w ill come on
~ page 14 . Do not con­
tin ue to operate the vehicle . The complete
brake sys tem should be thoroughly checked
by an authorized Audi dea ler or other quali ­
fied facility and the cause corrected.
If the
brake f lu id leve l is too low, the brake warning/
indica tor ligh t will illumi nate. Conta ct an au­
thorized Aud i de aler
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
en ced technician.
B rake fluid absorbs moisture from the air . If
the water content in the brake fluid is too
high, co rrosion in the brake system may resu lt
after a pe riod of time. The boiling point of the
brake f lu id will also dec rease conside rably and
decrease brak ing performance.
T herefo re , the bra ke fluid must be changed
every tw o year s. Always use new br ake f lu id
which con forms to Federal Mo tor Veh icle
Standard " FMVSS 116 DOT 4".
T he bra ke fluid reservo ir can be d iff icu lt to
reach, the refore, we recommend that you
have the bra ke fluid changed by your author­
ized
Audi dealer. Your dealer has the cor rect
tools, the right brake fluid and the know -how
to do this for you.
A WARNING
---- Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from old or inap­
prop riate brake f lu id. Observe these pre­
cautions:
- U se only brake fluid tha t meets SAE
specificat ion
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , when towing a trailer
very frequently, etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter .
(® For the sake of the environment
By regularly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment.
Important considerations for you and
your vehicle
