N .... 0 0 :c ' Using the proper engine oil is important for the
functionality and service 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 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- Vehicles with gasoline eng ine: ACEA A3 o r
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE SW-40.
- For more information about engine oil that has been approved for your vehicle, please
contact e ither your authorized Audi dea ler
or A udi Customer Relat ions at
1 (800) 822-2834 or visit our web site at

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 lubr ication and coo l­
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption varies from engine to en­
g ine and may change significant ly over the life of
Ch eck ing and Filling
the engine. Typ ica lly, engines with a specified
break-in period (see ¢
page 73) consume more
o il during the break -in per iod than they consume
after oil consumption has stabili zed.
Under normal cond itions, the rate of oil con ­
sumption depends on the quality and viscosity of
the oil, the RPM (revo lutions per minute) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of o il dilution from water condensa­
t ion or fuel residue a nd the oxidat ion level of the
o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary .
With a ll these variab les coming into play, no
sta ndard rate of o il cons umption can be estab­
l is h ed or spec ified. The re is no alternative to reg­
u lar and frequent checking of the oi l level, see
Note .
If the yellow engine o il leve l warning symbo l in
t h e instr ume nt cl uster
II lights up, yo u should
check the o il level as soon as possible
¢ page 2 76 . Top off the o il at your earliest con ­
venience
¢ page 276.
A WARNING
-Before you check anyth ing in the engine com-
partment, always read and heed all WARN­
INGS
¢ .& in Working in the engine compart­
ment on page 271 .
@ Note
Driving with an insufficient oil level is likely to
cause severe damage to the eng ine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the o il le vel. Do not rely on
i t. Instead, check the oil level in you r en­
g ine at regular inter vals, preferabl y each
time you refuel, and alw ays before go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amou nts of oil, we recom-
mend that you consult your Aud i dea le r to .,,.

Checking and Filling
have the cause of your concern properly di­
agnosed. Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
A pp lies to: ve hicles w ith oil leve l indicator
The engine oil level can be checked in the Info­
tainment system
Observe the safety precautions c:::> &. in Working
in the engine compartment on page 2 71.
.. Park your vehicle on a level surface.
.. Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
.. Select: the
ICARI function button > Car systems
control button > Servicing & checks> Oil level.
.. Read the oil level in the display . Add engine oil
if the bar in the oil level indicator is just before
"min"
<=:> page 276.
The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). Because of this, the
engine oil level must be checked regularly. It
would be best to check each time you refuel your
vehicle and before long drives.
@ Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in­
strument cluster. Add oil and close the hood.
The current oil level is displayed in the Info­
tainment system the next time the ignition is
switched on .

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over c urbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
.,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(D Note
-Please note that summer and winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ ­
er tires, which affects traction
Wheels
and braking ab ility. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, result ing in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or sim ilar
substances.

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions inc:::> page 295,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change . If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8- pillar, always follow the specifica-

negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the

Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom- mended tire pressures in cold ..

Wheels
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
296
carried in the vehicle (including
the weight of a trailer hitch and the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as l uggage .
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar

.&_ WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.

The effectiveness of wi nter tires is reduced g reat­
l y when the tread is wo rn down to a depth of
0.157 in ( 4 mm). The characte ris tic s of winter
ti res a lso decrease g rea tly as the t ire ages, re­
gard less o f the remaining t read.
_&. WARNING
- Never drive faster than the maximum pe r­
m itted speed for your tires . This could cause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose t ract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropr iate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
(i_) Tips
You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where wint er tires are required, o nly

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your tires is significant­
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
p roper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal ­
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: A8, 58
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.

If the press ure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
