Audi oil standard VW 502 00 (vehicles with gaso line e ngine) or VW
507 00 (vehicles w it h die sel eng ine).
Changing the engine oil
The eng ine oil and oil fi lter mus t be changed according to the mileage
(kilome ters) and t ime intervals specified i n your vehicle 's Warranty &
Ma intenance booklet . Do not exceed these interva ls - harmful
deposi ts from o ld engi ne oil can reduce engine pe rfo rmance and ca n
lead to expensive engine repa irs.
C hangi ng the oil at the recommende d interva ls is so very imp ortant
because the lubricating properties of o il decrease gradually during
normal ve hicl e use. If yo u ar e not sure w hen you have yo ur oil
changed, ask your author ized Audi Service Adv isor .
Under some circumstances the eng ine o il should even be changed
more fr eq uent ly. Chang e oil mor e of ten if you d rive mostly short
distances, operate the veh icle in d usty areas or mostly under stop­
and -go t raff ic condi tion s, or when you use yo ur vehicle where tempe r­
atures stay be low free zing po int for long periods.
De tergen t ad dit ives in the o il wi ll m ake fres h oil look dark a fter the
eng ine has bee n ru nning for a short t ime . This is normal and is not a
reason to ch ang e the oil mo re of ten t han re commended.
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your o il at the recommended intervals
using only en gine oil th at com plies wi th A udi o il st and ard VW 502 0 0
(vehicles w ith gasoline eng ine) o r VW 507 00 (vehicles with d iesel
eng ine) . Your Limited New Vehicle Wa rranty does not cover damage
or ma lfunct ions due to fa ilure to follow recomm ended maintena nce
and use requirements as set forth in t he Au di Owner's Man ua l and
W arranty
& M aintenance boo klet. Y ou r deale r will have to deny
wa rranty coverage unless yo u present to the dealer proof i n th e form

performed in a time ly ma nner. •
Engine oil consumption
To provide effective lubr ication a nd cooling for interna l eng ine parts,
a ll in ter na l c omb ustion e ngines use some oil. Oil cons umption v aries
from engine to engine and may change over the life of the eng ine .
E ngines te nd to use m ore oi l dur ing the b re a k-i n period t han t hey do
after ward, when oil consumption has stab ilized. Depending on t he
way the vehicle is driven and the operatin g cond itions, oi l cons ump ­
tion ca n be up to 1 qua rt pe r 1,200 m iles
(I liter per 2 ,000 km).
Consumption may be higher withi n th e first 3,0 00 miles (5,00 0 km).
Under nor mal co ndi tions, the rate o f oi l consu mptio n depe nds o n oil
quality as well as viscosity, engine speed ( rpm), o utside tempe rature,
roa d condi tion s, the amou nt of o il d ilution caused by co nde nsed
water or fu el residue, and oxidation of the oil. O il cons umption may
increase wi th en gine we ar ove r time, un til repl aceme nt of worn
eng ine pa rts may become necessa ry.
Because of all these var ia bles, there is no standa rd o r "norma l" rate
of oil consumption .
We urge you to check the engine oil level at
regular intervals, preferably every time you fill the fuel tank, and
always before a long trip .
The oil pressure warning light
~ is not an indicator of low eng ine
oil level. If the warning light does not go out after starting, or
flashes while driving (above 1500 rpm), a buzzer will sound . It
indicates that the oil pressure is too low. Stop the engine immedi- _.,,

& WARNING (conti nu ed )
• Engine oil is poisonous . Keep it well out of the reach of chil­
dren .
• Continuous contact with u sed engine oil is harmful to your
skin . Alway s protect your skin by wa shing thoroughly with soap
and water.
0 Note
Never mix oi l additives wit h your engine oil. These additives can
damage your engine and adverse ly affect your Audi Limited New
Vehicle Warranty.
~ For the sake of the environment
• Before chang ing the oil, first make sure you know where you can
prope rly d is p ose of the o ld oil.
• Always dispose of used oi l proper ly. Never dump it o n garden soi l,
in wooded areas, i nto streams o r down sewage d rains.
• Recycle used oi l by taking it to a used engine oil co llection facility
in yo ur area, or contact a se rvice station .
• We st rongly recommend t hat you have you r oi l changed by an
authorized Audi dealer or a qualified workshop with the specia l tools
and expertise required, and proper means of disposa l.•
Engine cooling system
Coolant
The e ngine co o la nt per form s two functio ns: it keeps the
engine from ove rh eati ng and it protects t he engine from
free zing in the winter .
The cooling system is sealed an d genera lly req uir es little attention. The cooling system has been f
illed at the factory wit h a permanent
c oo lant whi ch does no t need to be c hanged . Th e coolan t cons ists o f a
mixt ure of water and the manufacturer's glycol-basedcoolant addi ­
tive G12+ + antifreeze with anticorrosion ad dit ives (50% for USA
mode ls; 60% for Ca nadian models) . This mixture both ass ures the
necessary frost protection and protects meta l components in the
eng ine's cooling system from co rrosion and scaling. It also raise s the
boiling point of the coo lant .
Do not re du ce the co ncent ration of the coo lant in the summer by
add ing p la in water .
The proportion of coolant add itive must be at
least 50% but not more than 60%
to mai ntain an tifreeze pro tection
and coo ling efficiency . If the coolant frost p rotect io n i s too low, the
coo lant co uld freeze an d damage t he veh icle heating and engine
coo ling system .
For year-round driving, antifree ze is added at the factory for temper­
a tures dow n to:
• -31°F(-35°C)USA
• - 4 0 °F ( -40 °C) Canad a.
You can mix the G12 ++ coo lant addit ive w ith other additives (G12+ or
G 12). A lways check with yo ur autho rize d Audi dea ler.
& WARNING
Before you che ck anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 301 .
0 Note
• B efore w inter sets in, have the coolan t checked to see i f the
coo lant add itive in yo ur vehicle is s uff ic ient to meet the cl ima te
conditions. This is especially important if yo u live in a region where
the winter is ext reme ly cold . If necessa ry, increase the proport ion of
coo lant add itive to 60%.
• When ad ding coolant add itive to you r cooling sys tem, remembe r:_.,

___________________________________________ C_ h _ e_c _k _ i_n -=g ~ a_n _ d_ f_i _ll _i _ n -=g =--- ......J•
-We recommend using only coolant additive Gl2 ++ (check the
l a bel) for yo ur vehicle. This coolant ad dit ive is available at au tho·
r ized Audi dealers . Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coo lant . Adding radiator repa ir fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance .

ex pansion tank
Before you c heck anything in the eng ine compartment,
always read and heed all WARNINGS~ & in "Working in
the e ngine compartment" on
page 301.
- Turn off the ignit ion .
- Let t he eng ine cool down .
- Place a thick rag over the coolant expans ion tank
~ fig . 237 and carefully twist the cap counter ·clockwise
~ & -
Vehicle OP-eration
-Read the engine coolant level in th e open coo lant expan ·
sion tank ~ fig . 2 3 7 . With a cold engine, th e coolant level
should be between the "min" and "max" ma rkings . Whe n
the engine is warm , the level may be slight ly above the
"max" marking .
The location o f the coo lant expans ion tank can be seen in the engine
compartment illustration=>
page 302 .
To obt ain an accurate reading , the engine must be sw itched off.
Th e expans ion t an k in your vehicle is equippe d with an electric coolant
level sensor.
When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 35 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can oc cu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and
s team b y co ve ring the cap with a large, thi ck r ag.
• Turn the cap slowly and ver y carefully in a counter-clockwise
direction whil e applying light , downward pre ssure on the top of
thecap .

- Add coo lant.
- Tw ist the ca p on aga in
tightly .
Replacement eng ine coolant must conform to exact specifications
=>
page 308, "Coolant". Even in a n emergency, if coolant addi tive
Gl2 ++, Gl2 + or Gl2 is not available, do not use a different addit ive.
Use plain wate r in st ead until you can get the cor rec t additive an d can
restore the correct ratio. This shou ld be done as soon as possible. If
you have lost a considerable amount of coolant, then you sho uld
a d d c old an tifr ee ze and cold wa ter only when the e ngine is cold.
Always use
new engine coo la nt when refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
fo rced o ut thr ough the p re ssur e relief v alve in the c ap w hen the
eng ine becomes hot.
& 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
s team by covering the cap with a large, thi ck rag .
- Turn the cap slowly and very carefully
in a counter-clockwise
direction while applying light, downward pre ssure on the top
of the cap.
- To avoid being burned, do not spill antifreeze or coolant on
the exh aust system or hot engine parts . Under certain condi­
tions , the ethylene glycol in engine coolant can catch fire.
• Antifreeze is poisonous. Always store antifreeze in its original
container and well out of the reach of children.
• If you drain the coolant , it mu st be caught and safely stored in
a proper container clearly marked "poison ".
0 Note
• Coolant poll utes the environment and could cause an engine fire.
Excess coolant w ill be forced o ut thro ugh the pressure relief va lve in
t he c ap when t he e ngine becomes hot.
• If, i n an emergency, only water can be added, the co rrect ratio
