A WARNING
A child in a child safety seat installed with the
LA TC H l ower anchorages or w ith the standard
safety belt or a child in a booster seat on the
rear seat could play with unused rear seat
safety belts and become entangled. This
co uld cause the chi ld serious personal i njury
and even death.
Ch ild s afe ty
-Always secure unused rear seat safety belts
out of reach of children in child seats such
as by properly routing them around the
head restraint of the seat where the child
restraint is installed .
- Never activate the convert ible lock ing re­
tractor when rout ing the safety belts around
the head restraints.
- Never let anyone sit at the center rear seat­
ing position if the center rear safety belt has
been routed around a rear head restraint.
Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or
9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash .

A WARNING
If exceptional circumstances require the use
o f a forward- facing child restra int on the
front passenger's seat, the child's safety and
well-being require that the following special
precaut ions be taken:
- Make s ure the forward-facing seat has been
designed and cert ified by its manufact urer
for use on a front seat with a passenger
front and side airbag.
- Always follow the manufacturer's instruc­ tions prov ided with the ch ild safety seat or
infant carrier.
- Always move the front passenger seat to the h ighest position in the up and down ad­
justment range and move it back to the
rearmost position in the seat's fore and aft
adjustment range, as fa r away from the air­
bag as possib le, before insta lling the for­
ward-facing child res tra int.
- Always make sure that the safety belt upper
anchorage is beh ind the child restrain t and
not next to or in front o f the child restrain t
so that the safety belt will be properly pos i­
tioned.
- Always make sure that nothing prevents the
front passenger's seat from being moved to
the rearmost position in its fore and aft ad­
justment range.
- Always make sure the backrest is in an up­
right position .
- Never place or use any electrical device (such as a laptop, CO player, elect ronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
300
if the device is connected to the 12-volt
socket or the cigarette lighte r socket.
- If a seat heater has been ret rofitted or oth­
erwise added to the front passenger seat, never install any child restra int system on
this seat.
- Make sure that there are no wet objects (such as a wet towel) and no water or other
liquids on the front passenger seat cush ion .
- Never p lace objects on the seat (such as a
laptop, CO p layer, electron ic games device,
power inverte r or seat heater for ch ild
seats) . These may influence the elect rical
capacitance measu red by the capacitive pas­
senger detect ion system and can also fly
around in an accident and cause se rious per­
sonal injury .

Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas ­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts for the rea r seats and for the
front passenge r's seat have a conve rtible locking
r etractor for child safety seats. The safety belt
must be locked so that be lt webb ing cannot un ­
r eel. The retractor can be act ivated to lock the
safety belt and prevent the safety belt webbing
from loosening up dur ing norma l dr iving . A ch ild
safety seat can o nly be prope rly installed when
t h e safety be lt is locked so that the c hild and
c hi ld s afety seat will stay in place.
Always remember : Even though your veh icle is
equipped with an Advanced Airbag system, all
c hi ld re n, especially those 12 yea rs and you nger,
sho uld always ride in t he b ack seat p roperly re-
strained for their age and s ize.

Selective catalytic
reduction (AdBlue/DEF)
General information
App lies to: vehicles with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (AdBlue/DEF) is injected into the
exhaust system in front of a nitrogen oxide cata­ l ytic converter to reduce nitrogen em issions. The
urea solution is known as Ad Blue or DEF (Diesel
Exhaust Fluid) . The informat ion that follows w ill
u se the name Ad B lue .
The Ad Blue is carried in a separate tank in the ve­
hicle. The AdBlue consumption depends on the
dr iv ing behavior and veh icle operat ing cond i­
tions .
It is within a range of 1.0 L -3.0L every 600
miles (1,000 km). In some cases, the consump­
tion may a lso differ from this range depending
o n the dr iving behavior and vehicle operat ing
cond it ions.
When a message about refi lling the AdBlue ap­
pears in the instrument cl uster display, you must
refi ll the Ad B lue yourse lf or have it refilled by an
authorized Aud i dea le r o r a utho rized Audi Service

be lt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the veh i­
cle is stat ionary but the eng ine is running
and a gear is engaged . Otherwise, the veh i­
cle will start to move immed iately and this
could result in an acc ident.
- Pay attent ion to the following warnings
when work on the fue l system is required :
- Do not smoke .
- Never wor k nea r open flames .
- Always have a working fi re extingu isher
nearby.
- All work on the battery or electrical system
in your veh icle can result in inju ries, chemi­
cal burns, acc iden ts or bu rns . Because of
this, all work m ust be performed
onl y by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk o f electric shock and in ­
jury, never touch the following components
when the engine is running or is being start­
ed:
- Ign it ion cable
- Other components in the electronic high -
voltage ign ition system
- If you must check or perform work on the
engine wh ile it is running:
- Set the parking brake first and then se lect
the "P" selector lever position .
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can hang down into the engine .
- lim it your exposure to exhaust and chemi­
cals to as short a time as possible

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.

- 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.
