A ud i recommends Longlife h igh perform ance
e ngin e oil from Audi Genui ne Part s
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 usua lly be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage o r malfunctions due to failure
to follow recommended maintenance and use requirements as set fo rth in the Aud i Owner's
Manual and Warranty
& Maintenance booklet.
- Use only a high q ual ity eng ine oil that ex-
pressly complies with the Aud i oil q uality
standard specified for your vehi cle's engine .
Using any other oil can cause serious engine
damage .
- Do not mix any l ubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa ­
b le that meets the Audi oil quality standard
your eng ine requires, you may add a total of
no more than 0.5 qt (0.5 l) of a h igh-quality
"synthet ic" o il that meets the following speci­
fications .
- Vehicles with gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W -30 or SAE 5W-40 .
- Vehicles with d iesel eng ine : ACEA C3 or
API CF with a v iscosity grade of SAE OW-30
or SAE 5W -30 .

Engine oil consumption
The engin e in your v ehicl e dep ends on an ad e­
quat e amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lub rication and cool­
ing of inte rnal engine components, all inte rnal
combustion engines consume a certain amount
of oil. Oil consumption varies from eng ine to en­
gine and may change significantly over the life of
the engine. Typ ically, engines w ith a specified
break -in period (see
c> page 79) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has stabilized .
Under normal cond itions, the rate of oil con­
sumption depends on the qua lity and viscos ity of
the oil, the RPM (revolutions per m inute) at
which the engine is operated, the amb ient tem­
perature and road condi tions. Further facto rs a re
the amo unt of oil di lution from water co ndensa­
tion or fue l resid ue a nd the oxidation level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oi l consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the y ellow engine oil leve l warning symbo l Bl
in the instrument cluster lights up, you should
check the o il level as soon as possible
c> page 326. Top off the o il at your earliest con­
venience

-Carefully add 0.5 quart (0.5 liter) of the correct
oil ~
page 324 .
-Close the eng ine oil filler opening cap.
- Close the hood, restart the ignit ion after two
m inutes and read the current o il level in the In ­
fotainment system.
&_ WARNING
- When adding oil, do not let oil dr ip onto hot
engine components. This inc reases the risk
of afire.
- You must secure the cap on the oil fi ller
open ing correctly so that oil does not leak
ou t onto the ho t engine and exhaust system
when the engine is running, beca use this is
a fire hazard .
- Always clean skin thoroughly if it comes into
contact with engine oil.
(D Note
-The engine o il level must not be under the
" min" marking, because this incre ases the
risk of engine damage.
- If the message
II Plea se redu ce oil lev el
appears, there is too much oil in the eng ine
and there is a risk of damaging the cata lytic
converter and engine. Do not start the en­
gine . Contact an authorized A udi dealer or
authorized Audi Service Fac ility to have ex­
cess engine o il extracted if necessary .

:E: ' @ For the sa ke of the env ironment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
- The oil level indicator in the display is only
an informational disp lay. If the oil leve l is
too low, a minimum oil warning appears in
the instrument cluster. Add oil and close
the hood. The current oil level is displayed
in the instrument cluster the next time the
ignition is switched on .
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depend ing o n driving style and operating
cond itions. Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
ca use of th is, the engine oil level m ust be
checked regularly.
It would be best to check
each time you ref uel your vehicle and before
l ong drives.
Changing the engine oil
We recommend that hove your oil changed by an
authorized Audi dealer or a qualified service sta­ tion .
Before you check anyth ing in the engine compart­
ment,
al ways r ead and h eed all WARNIN GS~ &
in Working in the engine compartment on
page 322.
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 oi l should
be changed more frequently. Change oil more of­
ten if yo u drive mostly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Check ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem of proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi de aler or
a qual ified service stat ion.
If yo u choo se to ch ange your oil yo urself , please
note the following important information:
A WARNING "--

-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug w ith your
f ingers, 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 o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .

feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
