_& WARNING
An improper f uel ing p rocedure and improper
hand ling of fue l can lead to exp losions, fires,
severe b urns and other injuries .
- Do not smoke and keep away from open
flames .
- T he ig nition m ust be switched off whe n re ­
f ueling .
- Cell pho nes, radio devices and o ther radio
equipment s hou ld always be switched off
w hen refueling . Electromagnetic rays cou ld
cause sparks and start a fire .
- If you do not insert the fuel pump nozzle a ll
the way into the filler tube, then fue l can
leak out. Spilled fue l can ignite and start a
fire.
- Never get into the vehicle when refueling. If
there is an exceptional s ituation where the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle aga in . This will reduce the
r isk of electrostat ic d ischarge that can cause
flying sparks . Sparks can start a fire when
ref uel ing .
_& WARNING
We recommend that you do not t ransport any
fue l co nta iners in t he veh icle. Fue l cou ld leak
out of the containe r and ignite, espe cially dur ­
ing an accident. This can cause exp losions,
fires and injuries .
- If you must transport fuel in a fue l contain ­
er, please note the following:
Ch eck ing and F illing
- Always place a fue l container on the
ground before filling . Never fill the fue l
container with fuel while it is in or on the
vehicle . Electrostatic charge can occur
wh ile refueling and the fuel vapors could
i gnite .
- For fuel containers made of metal, the fuel p ump nozzle must always maintai n
contact with the conta iner to reduce the
r isk of s tat ic charge.
- Insert the fuel pump nozz le as far as pos­
s ible into the fi lle r opening w hile refuel­
ing .
-Fo llow lega l requ irements when using,
stor ing and t ransporti ng f uel conta iners.
- Make su re that the fuel containe r meets
t h e in dust ry standa rds, for example ANS I
o r ASTM F8S2 -86.
@ Note
- Remove fuel that has overflowed onto any
veh icle components immediately to reduce
the risk of damage to the vehicle.
- Never drive unt il the fuel
tank is completely
empty. The irregula r supply of fue l that re­
sults from that can cause eng ine misfi res.
U nc ombus ted fuel will ente r th e exhaus t
system and increase the risk of damage to
the cata lytic converter.
@ For the sake of the environment

Emissions control
system
Cat alytic converter
The vehicle may only be driven w ith unleaded
gaso line, otherwise the catalytic converte r will be
dest royed.
Never dr ive until the tank is completely empty.
The irregular supply of fuel that results from that
can cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over­
heating and damage to the catalytic converter.
&_ WARNING
The temperat ure of the exhaust system is
h igh, both when drivi ng and a fter stopp ing
the engine.
-
- Never tou ch the exhaust tail pipes once they
have become hot. This cou ld resu lt in burns.
- Do not park your vehicle over flammable
materials s uch as grass or leaves because
the hig h temperature of the emissions con­
trol system could start a fire .
- Do not apply unde rbody protectant in the
exhaust system area, beca use this increases
the risk of fire.

Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
Observe the safety precautions¢ A in Working
in the engine compartment on page 193.
~ Park your vehicle on a level surface.
~ Shut the engine off when it is warm.
~ Switch only the ignition back on.
~ Wait approx imately two minutes.
~ Select: the ICARI function button > ( C ar)* Sys ­
tem s
control button > Service & control > O il
l e v el.
~ Read the o il level in the I nfota inme nt system.
Add eng ine oil if the ba r in the oil leve l ind ica ­
tor is just before
"min"¢ page 198.
(UJ) Note
The engine oil leve l mus t not be unde r the
"min" mark ing, as this will increase the risk of
engine damage.
(D Tips
The o il level indica tor in the disp lay is on ly an
informationa l display. If the o il level is too
low, a minimum oi l warning appears in the in ­
strument cluster. Add oil and close the hood.
The current oil level is d isplayed in the Info­
tainment system the next t ime the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.S liter/1,000 km), de­
pending on driving style and operating condi­
tions. In RS models, the o il consumption may
be up to 1 qt/600 mi (0 .8 l/ 1,000 km). Con­
sumpt io n may be h igher du ring the first
3,00 0 miles (5, 000 km). Be cause of this, the
eng ine o il level must be checked reg ularly. It
Ch eck ing and F illing
is best to check each time you refue l yo ur ve ­
hicle and before long drives.
- In order to p rov ide effective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oi l consumption var ies
from engine to engine and may change sig­ nifica ntly over the life of the engine. Typi­
cally, eng ines with a specif ied break-in peri­
od consume more o il du ring the break-in pe­
r iod than they consume afte r oil cons ump­
tion has stabilized.
- Under norma l condit ions, the rate of oil
c ons umption depends on the q ual ity and
vis cos ity of the oil, the R PM (revo lutions per
m in ute) a t which the engine is operated, the
ambient temperature and road conditions .
Furt her factors are the amount of oi l di lu­
tion from water condensat ion or fue l resi ­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
- With all these var iables com ing into play,
no sta ndard rate of o il consumption can be
established o r specified. There is no a lter na­
ti ve to c hec king the oil leve l reg ula rly and
frequently.
- If you have the impress ion your engine co n­
sumes excessive amo unts of o il, we recom ­
mend that yo u consult an author ized A udi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that the
accurate measurement of o il consumption
requires great care and may take some
time. An authorized Aud i dealer has instruc­
tions about how to measure o il consump­
tion accurately.
