er display.
For the tank capacity in your vehicle, refer to the
Technical Data
¢ page 260.
(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
tor, an indicator light. will turn on when the
coolant temperature is too high ¢
page 19. Re­
fer to ¢(1) .
The coolant temperature indicator @c:>
page 10,
fig . 3 only works when the ignition is switched
on . To prevent engine damage, please observe
the following notes about the temperature rang­
es.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­ perature yet. Avoid high engine speeds, full accel­
erating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions . The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.

Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high

A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area . Stop the engine and al­
low it to cool before working in the engine
compartment. Always follow the informa­
tion found in ¢
page 198, Working in the
engine compartment.
(D Note
- In vehicles with a boost pressure indicator* ,
this indicator replaces the temperature dis­
play. To promote a long engine service life,
avoiding high engine speeds, full accelera­
tion and heavy engine loads during approxi­
mately the first 15 minutes when the en­
gine is cold is recommended . The amount of
time until the engine is warm depends on
the outside temperature . Check the engine
oil temperature* if necessary .
c:> page 30
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy engine
load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.

Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.

Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .

Engine 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 provide effective lubrication and cool­ ing of in ternal engine components, all internal
202
combust ion engines consume a certa in amoun t
of oil. Oil consumptio n varies from engine to en­
gine and may change sign ificant ly over the li fe of
the engine . Typically, eng ines with a specif ied
break-in period (see
¢ page 70) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has s tabilized .
Under normal cond itions, the rate of oil con­
sump tion depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
wh ich the engine is operated, the ambie nt tem­
perature and road cond it ions . Furthe r facto rs a re
t h e amo unt of o il di lution from water conde nsa­
t ion or fue l residue and the ox idat ion leve l o f the
o il. As any engine is s ubject to wear as mileage
builds up, the oil consumption may increase ove r
time unt il rep lacement of wo rn components may
become necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumption can be estab ­
li shed or spec ified. There is no alte rnative to reg­
ul ar and frequent checking o f the oil leve l, see
Note .
If the yellow engine oi l level warning sym bo l Ill
in the instrument cluster lights up, yo u should
check the o il level as soon as possible
¢ page 203. Top off the oil at your earliest con­
venience
¢ page 203.
A WARNING
Before you c heck anythi ng in the eng ine com ­
partment, always read and heed al l WAR N­
IN GS ¢page 198.
(D Note
Driving w it h an insufficient o il level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressure warning d isplay. is not
an indicator of the oil level. Do not rely on
it. Instead, check th e oil level in your en­
gine at regular intervals, preferably each
time you refuel , and alway s before going
on a long trip.

Checking and Filling
"' Check the oil level again after two minutes
¢ page 203 , Checking the engine oil level.
"'Add oil, if necessary.
"'Close the engine oil filler cap and push the dip­
stick all the way in.
A WARNING
- When adding oil, do not let oil drip onto hot
engine components. There could be risk of a
fire.
- You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
- Applies to vehicles with gasoline engines:
the oil level cannot be above the
0 range
¢ page 203, fig. 159, because this can
cause damage to the catalytic converter or
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess oil extracted if necessary.
- Applies to vehicles with diesel engines: the
oil level must not be in the
(v range
¢ page 203, fig. 160 -The oil must not be
extracted, because this can damage the en­
gine. Drive to an authorized Audi dealer or
authorized Audi Service Facility immediate­ ly .
- Do not mix any additional lubricants into
the engine oil. Damage cause by such addi­
tives is not covered by the warranty.
@ For the sake of the environment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements 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 service sta­ tion.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ page 198.
The engine oil must be changed according to the
intervals specified in your Warranty & Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oil should
be changed more frequently. Change oil more of ­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running 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 expertise re­
quired, 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 information:
A 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 engine
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 running down your
arm.

-Drain th e oi l into a container desi gned for
this purpose, one large enough to ho ld at
least the total amount of oil in your engine .
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuo us contact with used engine oil is
harmful to your sk in. A lways protect your
sk in by washing oil off thoroughly w ith soap
and water.
(D Note
Never mix oi l addit ives with your engine oi l.
These additives can damage your eng ine and
adversely affect your Audi Limited New Veh i­
cle 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 oil.
- Always d ispose of used engine oil proper ly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
d rains .
- Recycle used e ngine oi l 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 lit tle atten tion.
The cooling system has been filled at the factory
w ith a pe rma nen t coolan t which does no t need to
be ch anged . T he coolant consists o f a mixture o f
specia lly condit ioned wa ter and the man ufactu r­
er's glycol -based coolant additive Gl3 antifreeze
with anticor rosion add itives (SO% for USA mod­
e ls · 60% for Canadian models) . Th is m ixture bot h
'
assures the nece ssary fros t protection and p ro-
tects meta l components in the engine 's cooling
Checking and Fillin g
system from corrosion and scaling . It also raises
t h e boiling point of the coo lant .
D o no t redu ce the con cen tra tion of the coolan t in
the summer by ad ding plain water.
The prop or­
tion of coolant additive mu st be at least 50%
but not more than 60%
to maintai n antifr eeze
protection and cooling efficiency . If the coo lant
frost pro tec tion is too low, the coo lant co uld
freeze and damage the vehicle heating and en­
gine cooling system .
For year- ro und driving, antifreeze is added at the
factory for temperatures down to :
-- 31°F(-3S° C)USA
- -40 °F ( - 40 ° C) C anada.
If you must add coolant, use a mixture of water
and coolant additiv e. Mix ing the coo lant add it ive
with dis tilled wa te r is recommended .
A WARNING
Befo re you c hec k anythi ng i n the engi ne com ­
partment, always re ad and heed a ll WA RN­
IN GS
~page 198.
(D Note
- Befor e wi nter sets in , have the coo la nt
c hecke d to see if the cool an t additive in you r
vehicle is sufficient to meet the climate con ­
ditions . This is espec ia lly impo rtant if you
live in a region where the winter is extreme ­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to yo ur cool ­
ing system, remember:
- We recommend us ing o nly coo la nt addi­
tive G12 ++ o r G13 ( che ck the label) fo r
your ve hicl e. This coolant addi tive is av ail­
a ble at autho rized Aud i dea le rs . Othe r
types of ant ifreeze can significant ly re­
d uce corrosion protection. The resulting
corrosion can ca use a loss o f coolant and
serious engine damage.
- Do not add any type of rad iator leak sealant
to y our vehicle's engine coolant. Adding ra­
diator repa ir fluid may adversely affect the
function and perfo rmance of your cooling .,,.
