systems
Catalytic converter
Applies to vehicles a with gasoli ne engine : the
vehicle may only be driven with unleaded gaso­ li ne, otherwise the cata lytic converter will be de­
stroyed .
Never dr ive until the tank is complete ly empty.
The irregu lar supply of fuel that resu lts from that
can cause eng ine misfires. Uncombusted fue l will
enter the exhaust system, which can cause over­
hea ting and damage to the cata lytic converter .
Diesel particulate filter
Applies to vehicle s with a diesel engine : the die­
sel part icu late filter filters nearly all of the soot
particles out of the exhaust. The f ilter cleans it­
self automatically under normal dr iv ing cond i­
t ions .
If the filter cannot clean itself (fo r exam­
ple, bec ause you are only d rivi ng short distan­
c es), the filte r becomes clogged wi th soo t and

A WARNING
The temperat ure of the exhaust system is
h igh, both when driv ing and after stopping
the eng ine.
-
- Never touch the exhaust tail pipes once they
have become hot. This cou ld res ult in burns.
- Do not park your veh icle over flammable
materials such as grass or leaves because
the high temperature of the emissions con­ trol system (catalytic converter or d iesel
pa rtic ulate filter) could start a fire.
- Do not app ly underbody protectant in the

engine oil from Aud i Genuine Parts
Using the proper engine oil is important for the
functionality and service life of the eng ine. Your
engine was factory-filled with a high-quality oil
which can usually be used throughout the entire
year.
(D 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 Aud i Owner's
Manual and Warranty
& Maintenance booklet .
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine .
U si ng a ny other oil can cause serious engine
damage.
- Do not mix any lubr icants or othe r additives
i nto the engine oil. Doing so can cause en­
gine damage.
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 tota l of
no more than 0 .5 qua rt/liter of a h igh-quality
"synthetic"oil that meets the following speci­
fications.
- Vehicles with gasoline engine: AC EA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE SW-30 or SAE 5W-40.
- Vehicles with diesel engine: ACEA C3 or API CF with a viscosity grade of SAE OW-30
or SAE 5W-30.
- For more information about engine oil that
has been approved for your vehicle, please

Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool all of
its moving ports.
In order to provide effective lubrication and cool ­
ing of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ignificantly over the life of
the engine. Typ ically, engines w ith a specified
break-in period (see
c::> page 73) consume more
o il during the break-in per iod than they consume
after oil consumpt ion has stabil ized.
Under normal cond itions, the rate of oil con­
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the amb ient tem­
peratu re and road co ndit ions. Furt her fac to rs a re
the amo unt of oil di lution from wate r condensa­
tion or fuel residue and the oxidation level of the oi l. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Not e.
If the yellow engine oil level warning symbo l El
in the instrument cluster lights up, you should
check the oil level as soon as possible
c::> page 308 . Top off the o il at your earliest con­
venience

on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized Aud i
dealer to have the cause of your concern
properly d iagnosed . Keep in mind that the
accurate measurement of oil consumpt ion
r equi res great ca re and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
.. Park you r vehicle on a level surface.
.. Shut the engine off when it is warm.
.. Switch only the ignition back on.
.. Wait approximately two minut es .
.. Se lect in the Infotainment system: the

& c h ecks > Oil lev el.
.. Check the oil level in the Infotainment system
display . Add engine oil if the bar in the oil level
indicato r is near "min "¢
page 308 .
The engine oil consumpt ion may be up to
0 .5 quart pe r 600 miles (0.5 l iter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be highe r d uring the
fi rst 3 ,000 mi les (5,000 km). Because of this, the
engine o il level must be checked regu larly. I t
wou ld be best to check each time you refuel your
vehicle and before long drives .

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 c> A
in Working in the engine compartment on
page 304 .
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 cond it ions, or have your vehi­
cle whe re temperatures remain below freezing
for extended pe riods.
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time. This is no rmal 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
qu ired, we strong ly recommend that you have
Checking and Filling
your oi l changed by an authorized Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important info rmation:
A WARNING ~
To reduce the risk of persona l 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 remov ing 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 the oil into a container designed for
this purpose, one large enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water.
CD Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
-Before changing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine o il properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
