Using the proper engine o il is important for the
functionality and serv ice life of the engine. Your
engine was facto ry-filled with a high-qua lity oil
which can usually be used throughout the entire
year.
(D Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Ma intenance booklet.
- Use only a high qua lity eng ine oil that ex-
pressly complies w ith the Audi o il quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthe tic"oil that meets the followi ng speci­
fications.
- Vehicles with gasoli ne engine: AC EA A3 o r
API SM wi th a viscosity g rade of SAE OW-30,
SA E SW-30 or SAE SW-40 .
- Vehicles wi th d iesel engine: AC EA C3 o r

· Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all of
its moving parts.
In order to prov ide effective lubrication and coo l­
i ng of internal engine components, all internal
combust ion engines consume a certa in amount
of oil. Oil consumpt ion va ries from engine to en­
gine and may change sig nificantly over the life of
the engine. Typically, eng ines wi th a specified
break -in period (see¢
page 198) consume mo re
o il during t he b reak-in period than they co nsume
after oil consumption has stabilized .
Un der normal cond itions, the rate o f oi l con­
sumption depends on the q uality and viscos ity o f
the oil, the RPM (revolutions per min ute) at
which the engine is operated, the ambient tem­ perature and road condit ions. Further factors are
the amount of o il dilution from water condensa­
tion or fuel residue and the ox idat ion leve l of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may inc rease over
time unt il rep lacement of worn compone nts may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be estab­
li shed or spec ified. There is no alte rnative to reg­
u lar and frequent checking of the oil leve l, see
Note .
If the yellow engine oil leve l warning symbo l in
the i nstrument cluster

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check any thing in the engine compart­
ment,
always read and heed all WARNINGS c> .&.
in Working in the engine compartment on
page 221 .
The engine oil must be changed according to the i n terva ls specified in your Warranty
& Mainte­
nance booklet . This is ve ry impo rtant because the
lubricat ing propert ies of o il diminish gradua lly
du ring normal ve hicl e use.
Unde r some circumstances the eng ine o il should
be changed more frequent ly. Change oil more of­
ten if yo u drive most ly short distances, operate
t he vehicle in d usty areas or unde r predom inan tly
s top-and-go traff ic co ndit io ns, o r have you r vehi ­
cle where tem peratures rema in be low freezing
for extended periods .
226
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running fo r a
short time. Th is is norma l and is not a reason to
c h ange the oi l more often than recommended.
Beca use o f the p rob lem of p roper disposal, along
with t he specia l too ls and necessary expertise re­
quired, we strongly recommend that yo u have
your oi l changed by an authori zed
Audi dealer or
a q ua lified service station.
If you choose to change your oil yourself , please
note the fo llow ing important info rmat ion:
_& WARNING
To reduce the risk of personal inj ur y if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce t he risk of burns from hot eng ine
oil, let the engine coo l d own to the to uch.
-
- W hen removing the o il dra in p lug with your

Cooling system
Coolant
T he 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 sealed and generally re­
qu ires little attention .
T he cooling system has been filled at the factory
with a permanent coolant which doe s not need to
be changed . T he cool ant consists of a mixture of
specia lly condit io ned water and the ma nufactur ­
e r's g lycol-basedcoo lant additive G 13 antifreeze
w ith a nticorros ion add itives (50% for USA mod­
e ls; 60% for Canadian models) . Thi s m ixt ure bot h
a ssures the ne cessary frost protection and pro­
tec ts meta l components in the engine 's cooling
system from corrosion and sca ling. It a lso raises
the boiling point of the coolant.
D o not red uce the conce ntra tion o f th e coo lant i n
the summer by add ing p la in wa ter.
The propor­
tion of coolant additive must be at least 50% but not more than 60 %
to maintain antifreeze
protection and cooling efficiency . If the coolant
frost protection is too low, the coolan t could
freeze and damage t he vehicle heat ing and en­
g ine cooling system .
For yea r-round driving, antifree ze is added at the
factory for tempe ratu res down to:
- -31°F ( -35°C) USA
- - 4 0°F ( - 40°C) C anada .
I f yo u mu st add coo lant, use a m ixt ure of wate r
a nd coolant add it ive. Mixing the coolant additive
with d istilled water is recommende d.
_& WARNING
Be fore yo u check any thing i n the engine com ­
par tment, always read and hee d all WAR N-
Checking and Fillin g
IN GS ¢ .& in Working in the engine compart­
ment on page 221.
@ Note
- Be fore winte r sets in , have the coo lant
checke d to see if the coolant additive in you r
vehicle is sufficient to meet the climate con­ diti ons. This is espec ia lly important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the p ropo rtion
o f coolan t addi tive to 60%.
- Whe n adding coolant additive to your cool­
ing system, remember :
- We recommend using o nly coo lan t add i­
tive G12++ o r G13 fo r yo ur vehicle . This
coolant ad dit ive is available at author ized
A ud i dealers . Othe r types of antifreeze ca n
significantly reduce cor rosion protect ion .
The resulting cor rosion can ca use a loss of
coolant a nd serious e ngine damage .
- Do not add any type of rad iator leak sealant
to your vehicle's engine coolant. Adding ra­ diat or repa ir flu id may adverse ly affect the
function and perfo rmance of your cooling
system and cou ld result i n damage not cov­
ere d by your New Vehicle Lim ited W arra nty .

Checking and Filling
"'Park your vehicle on a level surface.
"'Turn off the ignition.
"'Read the engine coolant level from the coolant
expansion tank
c:> fig . 200, <=> page 223,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark­
ings . When the engine is warm, the level may
be slightly above the "MAX" marking .
The location of the coolant expansion tank can be
seen in the engine compartment illustration
<=> page 223 .
To obtain an accurate reading, the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
c::> page 29 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric 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 cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant .
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
0 Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .

or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifree ze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying

tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original conta iner and well out
of the reach of ch ildren .
-If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do not continue driving. Seek profess ional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire . Excess coolant will be

@) For the sake of the environment
Drained coolant should not be reused. Always
dispose o f used coolant while observ ing all
environmental regulations .
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt . The viscous clu tch regulates the speed of
the fan ac cording to the temperature of the cool ­
ant.
An auxiliary e lectr ic rad iator fan* switches on and
off depend ing on coolant temperat ure and othe r
veh icle operating conditions.
Afte r you switch the engine off, the auxiliary fan
can continue runn ing for up to 10 minutes -even
Ch eck in g and Fillin g
with the ignition off . It can even switch on again
later by itself¢& , if
- the temperatu re of the engine coo lant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
veh icle is parked in intense sun light .
A WARNING
-To reduce the risk of persona l injury never
touch the radiator fan .
- The auxiliary electric fan is temperature con­ trolled and can switch on suddenly even
when the engine is not running.
- The a uxiliary radiator fan sw itches on auto­
matica lly when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 223.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on¢
page 18 and ¢ page 28 . Do not
continue to operate the vehicle . The complete
brake system shou ld be thoroughly checked by an
author ized Audi dealer or qualif ied workshop and
the cause corrected. If the brake fluid level is too low, the brake warning/indicator light will illum i­
nate. Contact an authorized Aud i dealer
immedi ­
a tel y.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake flu id abso rbs moisture from the a ir . If the
water content in the brake fluid is too high, cor­ rosion in the b rake system may result after a pe ri­
od of time. The boiling point of the bra ke fluid
will also decrease conside rably and decrease
b ra ki ng per fo rmance .
Therefore, th e brake flu id must be changed
ev ery
tw o years .
Always use new b rake fluid w hich con­
forms to Fede ra l Motor Vehicle Standa rd " FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re, we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer .
Your dealer has the cor rect too ls, the
right brake f luid and the know -how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old or inappro­
pr iate brake fluid . Observe these precau­
t ions:
230
- Use only brake fluid that meets SAE spec i­
ficat io n
J 1703 and conforms to Federal
Motor Vehicle Sta ndard 116 . Always check
with your aut horized Aud i dea ler to make
su re you are using the correct brake fl uid .
The co rrect type of brake f lu id is also ind i­
cated on t he b rake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the b rakes can cause a vapor lock if the
brake fluid is left in t he system too long.
This can se riou sly affec t the efficiency of
the b rakes as well as yo ur sa fety. This
could result in an acc ident .
