high, both whe n driving and after stopping
the engine .
- Never touch the exhaust ta il pipes once they
have become hot. This could result in burns .
- Do not park you r vehicle over flammable
materials such as g rass or leaves because
the h igh temperat ure of the emiss ions con­
t rol sys tem cou ld start a f ire.
- Do not apply underbody p rotectant in the
exha ust system a rea, because this increases
the risk of fire.
- Applies to: vehicles wi th diesel particulate
filte r: always adjus t your speed to the

dur ing diesel partic ulate fi lter regene ration.
Yo u should never disobey tra ffic laws in or­
der to fo llow dr iv ing recommendations.
(D Tips
Applies to: ve hicles with diesel particulate filter
- Due to the high temperatures that occur
d uring diesel pa rticu late filter regenerat ion,
the radiator fan may continue runn ing after
the engine stops, even if the engine did not reach its operat ing temperatu re.
- Noises, odors and increased speeds may oc­
cur d uring the regeneration.
- Always use the co rrect engine oil and fuel to

Checking and Filling
- Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
forn ia to cause cancer and birth defects and
reproduct ive harm . In addition, certain flu­
ids contained in veh icles and certain prod­
ucts of compo nent wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm .
- Battery posts, termina ls and related acces­
sories contain lead and lead compounds, chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling .
(D Note
When filling flu ids, be sure not to mix the flu ­
ids up . Otherwise severe ma lfunctions and en­
gine damage w ill occur .
@ For the sake of the environment
You shou ld regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids,
bring your vehicle to an authorized Audi deal­
er or author ized Audi Service Facility to be
checked .
Opening/closing the hood
The hood is released from inside the vehicle.

"' Raise the hood slightly~ &-
"' Press the lever~ fig. 262 in the direction of the
arrow. This releases the hooks .
"' Open the hood.
Closing the hood
"' Push the hood down until you over ride the
force of the struts .
"' Let the hood fall lightly into the latch .
Do not
press it in.
~ .&_ .
A WARNING
-Never open the hood when there is steam or
coo lant escaping from the engine compart­
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
- For safety reasons, the hood must always be
closed securely while driving . Because of
this, always check the hood after closing it
to make sure it is latched correctly . The
hood is latched if the front corners canno t
be lifted .
- If you notice that the hood is not latched
while you are driving, stop immed iate ly and
close it, because driving when the hood is
not latched increases the r isk of an accident . ..,.

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 319.
~ 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 in the Infota inment system: the I MENU I
button > Ve hicle > left contro l button > Ser vic e
& chec ks > Oil level.
~ Read the oi l level in the display . Add engi ne oil
if th e ba r in the oil leve l ind icator is j ust before
"min" ¢
page 323.
{U) Note
The engine o il leve l must not be unde r the
"min" marking, as this will increase the risk of
engine damage .
(D Tips
The oil level indicato r in the display 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 oi l and close the hood.
The current oil leve l is d isplayed in the Info­
tainment system the next time the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this, the engi ne oil level m ust be chec ked regular·
Ly. It is best to c hec k each t ime yo u refuel
your veh icle and before long dr ives.
322
- In order to prov ide e ffective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oil consumption var ies
from engine to eng ine and may change sig­
nificantly over the life of the engine. Typi·
cally, eng ines with a specified break-in per i·
od consume mo re o il during the break-in pe·
r iod than they consume afte r oil cons ump·
t ion has s tabilized.
- Under no rma l co nd it ions, the rate of oil
c ons umption depends on the q ual ity and
vis cos ity of the oil, the RPM (revo lutions per
min ute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu ­
t ion from water condensation or fuel resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage bu ilds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
- With all these var iables comi ng into play,
no standard rate of o il consumption can be
established o r spe cified. There is no alter na­
t ive to c hec king the oil leve l reg ularly and
frequently.
- If you have the impress io n your e ng ine co n­
s u mes excessive amou nts of oi l, we recom ­
mend that yo u consult an authorized A udi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that the
acc urate measurement of o il cons umption
requires great care and may take some
t ime. An authorized Aud i dealer has instruc­
t ions about how to measure o il consump·
t ion accurate ly.
