Check ing and F illing
Using the proper engine oil is impo rtant for the
functionality and service life of the engine. Your engine was facto ry-filled with a h igh-quality oi l
which can usually be used throughout the entire
year.
@) Note
Your Limited New Vehicle War ranty 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 Warran ty
& Maintenance booklet.
- Use only a high quality eng ine oil t hat ex-
p ressly complies with the Audi oil qua lity
standard specified for your vehicle's engine .
Using a ny o ther oil can cause serious engine
d am age.
- D o not mix any lubricants o r other addit ives
i nto the engine oil. Doing so ca n cause en­
g ine damage.
(D Tips
I f you need to add oil and there is none availa­
ble t hat meets the Audi o il quality standard
your eng ine requi res , you m ay ad d a tot al of
no more than 0.5 q t (0,5

"synthe tic"oil that meets t he following speci ­
fications.
- AC EA A3 o r API SM wi th a viscosity grade o f
SAE 0W-30, SAE 5W-30 or SAE 5W-40.

Engine oil consumption
T he engine in your vehicle depends on an ade­
quate amoun t of oil to lubricate and cool all of
i ts moving par ts.
In order to p rovide effective lubr ication and cool­
ing of internal engine components, all interna l
combustion engines consume a cer tain amount
of oil. Oi l co nsumption varies from engine to en ­
g ine and may change significant ly over the life of
the eng ine . Typically, eng ines with a specified
238
b reak -in period (see q page 57) cons ume more
oi l during the break-in period than they consume
after o il consumption has stab ilized.
U nder normal cond itions, the ra te of oil con ­
s u mption depends on the q ua lity and viscos ity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further facto rs a re
the amount of o il di lution from wate r condensa­
tion or fue l resid ue a nd the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the o il consumption may increase ove r
ti me until replacement o f wo rn components may
become ne cessary.
With a ll these va riables coming into p lay, no
standard rate of o il consumption can be estab­
li sh ed or spec ified . T he re is no alte rnative to reg­
u lar and freq uen t che cki ng of the oil level , see
Note .
If the yellow engine oil level warning symbo l l!I
in the instrument clus ter lights up , you sho uld
c h eck t he o il level as soon as poss ible
q page 239 . Top off the o il at your earlies t con­
venience

_& WARNING
Before you check a nyt hing in the en gine com ­
partment, always read and heed all WARN­
INGS
9 page 235.
@ Note
D riving w ith an insufficient oil level is like ly to
cause severe damage to the eng ine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals , preferably each
time you refuel, and always befo re going
on a long trip .
- If you have the impress io n your engine con­
sumes excessive amounts of oil, we recom­
mend that yo u consult an authorized A udi
dea le r to have t he cause of your concern
properly diagnosed. Keep in mind that the .,.

Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant level is monitored through the. in­
dicator light
¢page 12. However , we do recom­
mend occasionally check ing the coo lant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freez ing and
corros ion protection agents. Only use the follow­
ing coolant addit ives . These additives may be
mixed with each other.
Coolant additive Specification
G13 TL 774
J
G12++ TL 774 G
The amount of coo lant add itive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi­ tive percentage is too low, the coolant can freeze
and damage the engine.

(D Note
- Before the start of winter, have your author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate . Th is is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the r isk of burns
from hot coolant:
- Do not open the coolant expansion tank cap when the eng ine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure o n the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­ haust system or hot eng ine components .
T he ethylene glycol in eng ine coolant can
catch fire under certa in circumstances.
- The coo lant add itive and the coolant can be
dange rous to your health. For this reason,
keep the coolan t in the origina l container
and away from children. There is a risk of
poisoning.
- When working in the engine compartmen t,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of inj ury.
(D Note
Do not add coolant if the exp ansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving. See an authorized Audi deal­
