the expansion space in the tank will fi ll,
which can result in fuel spilling out when it
becomes warm and polluting the environ ­
ment.
(D Tips
- If
the engine is running while fueling, va­
pors can escape or the fuel can spill over.
Because of th is, the fuel nozz le switches off
before th e tank is full.
- Do not fue l the vehicle when the ignition is
switc hed on. Otherwise, the fuel gauge may
not show the correct level after fueling the
vehicle.
- Diesel vehicles are equipped with a diesel
misfueling guard
l). It allows the vehicle to
be fueled on ly w ith a diesel fuel p ump noz­
zle .
- A worn o r damaged nozzle or a nozz le that
i s too sma ll may not be able to open the die­
se l m isfue ling protector. If this is the case,
try turning the no zzle before inser ting it in
the fue l filler neck, use a different fuel
p ump or see an a uthorized Audi dea le r or
a uthorized Audi Service Facility for assis­
tance .
- The misfueling guard does not o pen whe n
adding fue l from a fuel contai ne r. Yo u can
bypass it by adding the diese l fuel s low ly .
- The fuel filler door on your vehicle does not
l ock when you lock the vehicle from the in­
side.

Catalytic converter
App lies to vehicles: with gasoline e ngine
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .

The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fue l spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
f uel will a lready se riously degrade the
performance of the c ata lytic conver ter.
- Do not exceed the co rrect engine oil leve l
9page203.
-Do not d rive until the fuel tank becomes
complete ly empty. The eng ine could misfi re.
U nburned f uel co uld also ge t in to the e x­
haust system and this could ca use the cata ­
l ytic converter to overheat.
- Do no t sw itch off the ignition wh ile the vehi­
cle is moving.
- Do not con tinue to oper ate yo ur vehicle un­
der these cond itions, as o therwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.
- To assure efficient ope ration of the Emission
Control System:

- Have your vehicle maintained properly and
in accordance with the serv ice recommen­
dat ions in yo ur Warranty
& Maintenance
booklet.
- Lack of prope r maintenance as we ll as im­
p roper use of the vehicle will impair the
f u nction of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exha ust gas can have a
su lfur-like exhaust gas sme ll under some op­
erating states. Th is depends on the s ulfur
content of the fuel b eing used. Us ing a diffe r­
ent bra nd of fue l may he lp, or fi lling the tank

Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
T he diese l part icu late filter filters nearly all of
the soot pa rticles ou t of the exha ust. The filter
cl ea ns itself a utoma tic all y unde r no rm al driving
con dit ions. If the filte r cannot clean itse lf (for ex­
amp le, because yo u are only driving sho rt distan ­
ces), th e fi lter becomes clogged with soot and

Selective catalytic
reduction
General information
App lies to vehicles: wit h diese l eng ine
In veh icles with selective catalytic reduction, a
u rea solution (AdBlue) is injected into the ex­
haust system before a nitrogen oxide cata lytic
conve rter to redu ce nitrogen emissions.

Ad Blue is the market ing name for Diese l Exhaust
Fl uid (DEF) .
The AdBlue is carried in a separate tank in the ve ­
h icle. The AdB lue usage acco unts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used .
When a message about refil ling the Ad Blue ap­
pea rs in the instrument cluster disp lay, yo u must
refill the AdBlue yourself or have it refilled by an
authorized Aud i dealer or authorized Audi Se rvice
Facility ¢

A WARNING
Failure to heed Ad Blue refill information in
the instrument cluster can prevent the vehicle
from be ing started and driven. If the veh icle
cannot be driven and an emergency arises,
personal in ju ry can occur.
-Always have the Ad Blue tank refilled well before the tank runs d ry.
(D Tips
-
- The instrument cluster display indicates the
distance remaining that can be driven
¢ page 196. If the AdBlue tank is com ­
plete ly empty, the engine w ill not start

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.
@) Note
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.

-If you have the impression your engine con­
sumes excessive amounts of oi l, we recom­
mend that you consult an authorized Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate measurement of oil consumption
requires great care and may take some time.
An authorized Audi dealer has instr uctions
about how to measure oil consumption ac­
curately.
Checking the engine oil level
Fig. 159 Gasoline engine oil dipstick: guide for measuring
t h e oil leve l (example)
F ig . 160 Diesel engine oil dipstick : g ui de for measuring the
oil level (example)
Determining the oil level
• Park your vehicle on a level surface.
• Let the engine run in idle briefly while it is at
operating temperature and then shut the en­ gine off.
• Wait approximately two minutes.
• Remove the oil dipstick. Wipe off the oil dip­
stick with a clean cloth and insert it all the way
in again .
• Remove the dipstick again and then read the oil
level¢
fig. 159 or ¢ fig. 160.
Checking and Filling
• Evaluate the oil leve l c;, table on page 203. Add
engine oi l if necessary
¢ page 203.

cility immediately.
Applies to vehicles with diesel engines: if you op ­
erate your vehicle with biodiesel, fuel may enter
the engine oil. This raises the oi l level in the en­
gine. It also decreases the quality of the engine
oil ¢page23.
The oil consumption of the engine may be up to
1/2 quart per 600 mi les (0 .5 liter per 1,000 km),
depending on driving style and cond itions. Con­
s umption may be higher during the first
3,000 miles (5,000 km). Because of this, the en­
gine oil level must be checked regularly. It would
be best to check each time you refue l your vehicle
and before long drives.

General information
~check your tires regularly for
damage (punctures, cuts, crac ks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs 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 i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
214
and braking ability. If summer
tires are used in very cold tem­ peratures, cracks can form on
the tread bars, resulting 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 similar
substances.
