-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the AdBlue tank. Mixing can
lead to damage to the engine and the Ad Bl­
ue tank system .
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as poss ible with a
damp cloth and plenty of cold water . If the
Ad Blue has already crysta llized, use warm
water and a sponge. Ad Blue residue that is
not removed will crysta llize and can damage
the affected surface.
- Do not store refill bott les or canisters per­
manently in the vehicle. If the container
l eaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa­
ter.

Using the prope r engine oil is important for the
functiona lity and service life of the eng ine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year.
@ Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Maintenance booklet.
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious 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 o il quality standard
your eng ine requ ires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the followi ng speci­
fications.
- Vehicles with gasoline eng ine: AC EA A3 o r
API SM wi th a viscosity g rade of SA E OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles wit h diesel eng ine: ACEA C3 o r

Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly ove r the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
¢ page 194) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l in
the instrument cluster
II lights up, yo u should
c h eck the o il level as soon as possible
¢ page 220. Top off the o il at your earlies t con­
venience

A WARNING
--=-
Before you check anything in the engine com-
partment, always read and heed all WARN­
INGS

ment on page 216.
(D Note
Driving wit h an insufficient oil level is likely to
cause severe damage to the eng ine.

Checking and Filling
@ 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 consu Lt your Audi dealer to
have the cause of your concern properly di­
agnosed . Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
Fig. 187 I n fo tai nme nt: oil level indic a to r
• Park your vehicle on a level surface.
" Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
" Select : the
ICAR I function button > (Car)* Sys­
tems
control button > Service & control > Oil
level.
.. Check the oil level in the Infotainment system
display ¢
fig. 187. Add engine oil if the bar of
the oil level indicator is near "min"
¢page 220.
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0 .5 liter per
220
1,000 km). Consumption may be higher within
the first 3,000 miles (5,000 km).
Because of this, the engine oil level must be
checked regularly. It would be best to check each
time you refuel your vehicle and before long
drives.
{!) Tips
The oil level indicator in the instrument clus­
ter display is only an informational display. If
the oil level is too low, a minimum oil warning
appears in the instrument cluster. Add oil. If
the hood was opened, the current oil level is
shown in the instrument cluster the next time
the ignition is switched on.

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 216.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
l ubricat ing propert ies of oil d iminish gradually
during normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck 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 o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authorized
Audi dealer or
a qual ified service stat ion.
If y ou choo se to chan ge your oil your self , please
note the following important information:

-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
he lp 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 amou nt 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
