Using the proper engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
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 & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 qt (0,5 l) of a h igh-quali ty
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please

www.audiusa.com or www.audican ada.ca .
Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
~ combustion engines consume a cer tain amount
;:::: of oil. Oil consumption varies from engine to en-
" ~ gine and may change sign ificantly over the life of 0
~ the eng ine . Typically, eng ines with a spec ified c:o
Ch eck ing and Filling
break-in period (see ¢ page 55) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢
page 248 . Top off the o il at your earliest con­
venience ¢
page 248.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS¢
page 244 .
(D Note
Driving with an insufficient oil level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressure warning display. is not
an indicator of the oil le vel. Do not rely on
it . Instead, check the oil level in your en·
gine at regular intervals , preferabl y each
time you refuel, and always befo re going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern
prope rly diagnosed . Keep in mind that the .,,.

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 risk 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 on the cap .
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex­
haust system or hot engine components .
The ethylene g lycol in engine coolant can
catch fire under certain circumstances.
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine. If this is the case, do not
cont inue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.

Vehicles with an automatic transmission can­
not be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
