Using the proper engine oil is important for the
functionality and service life of the eng ine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
0 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
Man ual and Warranty
& Maintenance booklet.
- Use only a high qual ity eng ine oi l th at ex-
p ressly complies with the Audi oil q uality
standard specified for your vehicle's engine .
Using any other oil can cause se rious engine
damage .
- Do not mix any lubricants or 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
ble that meets the Audi oi l quality standard
your engine requi res, 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 w ith diesel eng ine: ACEA C3 or
API CF with a v iscosity grade of SAE OW-30
or SAE 5W-30 .

Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all of
its moving ports.
In order to prov ide effect ive lub ricat ion and cool
ing of internal engine components, all internal
combustion engines consume a certain amount
of oil. Oil consumption var ies from engine to en
gine and may change significantly over the life of
the engine. Typically, engines w ith a specified
break-in period
(see<=> page 80) consume more
o il dur ing the break-in per iod than they consume
after o il consumption has stabi lized .
U nder normal cond itions, the rate of oil con
sumption depends on the quality and viscos ity of
the oil, the RPM (revolutions per m inute) at
wh ich the engine is operated, the amb ient tem
perature and road condit ions. Furthe r facto rs a re
t h e amo unt of o il di lution from wate r condensa
t ion or fue l residue a nd the oxidat ion level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
ti me until replacement of worn components may
become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil cons umption can be estab
li shed or specified . There is no alternative to reg
ular and frequent checking of the oil level, see
Note .
If the yellow engine oil leve l warning symbo l El
in the instrument cluster lights up, you should
check the o il level as soon as possible
<=> page 32 7. Top off the o il at your earliest con
venience
<=> page 32 7.

Driving with an insufficient oil level is likely to

@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
-If you have the impression your engine con
sumes excessive amounts of oil, 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 instruc
tions about how to measure oil consump
tion accurately.
Checking the engine oil level and adding
engine oil
The engine oil level can be checked in the Info
tainment system

-Switch only the ignition back on. Wait approxi-
mately two minutes so that the engine oil can
flow back into the oil pan .
Checking and Filling
- Select in the Infotainment system: the !MENUI
button > Vehicle > left control button > Service
& checks > Oil level.
-Check the oil level in the Infotainment system
display. Add engine oil if the bar in the oil level
indicator is just before "min".
Adding engine oil Follow the safety precautions
~&. in Working in
the engine compartment on page 323.
- Stop the engine and open the hood
~page 324 .
-Unscrew the cap~ on the engine oil filling
opening
~ fig. 269, Qpage 325.
- Carefully add O .S quart (O .S liter) of the correct
oil
~ page 325.
- Close the engine oil filler opening cap.
- Close the hood, restart the ignition after two
minutes and read the current oil level in the In
fotainment system.
A WARNING ...__ --When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of afire.
-You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
-Always clean skin thoroughly if it comes into
contact with engine oil.
0 Note
- The engine oil level must not be under the
"min" marking, because this increases the
risk of engine damage.
- If the message II Please reduce oil level
appears, there is too much oil in the engine
and there is a risk of damaging the catalytic
converter and engine. Do not start the en
gine. Contact an authorized Audi dealer or
authorized Audi Service Facility to have ex
cess engine oil extracted if necessary.
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi-
tives is not covered by the warranty.

Coolant
The engine coo ling system is filled with a mixture
of purified water and coolant additive at the fac
tory. This coolant must not be not changed.
The coolant level is monitored through
the. in
dicator light
¢ page 30. However , we do recom
mend occasiona lly checking the coolant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti -freezing and
corrosion protection agents. Only use the fol low

mixed with each other.
Coolant additive Specification

The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated. If the coolant addi
