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 86) 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 334. Top off the o il at your earliest con­
venience

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Wheels
check you r tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and t ire tread life,
a nd may affect the veh icle's handling and stop ­
p ing ability .
Please note that the TPMS is not a substit ute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level

Your veh icle has also bee n eq uipped w ith a TPMS
malfunct ion i nd icator to indicate when the sys­
t e m is not operat ing properly. The TPMS ma l­
f u nction indicator is comb ined w ith the low tire
p ress ure tellt ale. Whe n the system dete cts a
malfunct ion, the te lltale will flash for approxi­
mate ly one min ute and then remain continuo usly
i l luminated. This sequence will continue upon
subseq uent veh icle start- ups as long as the ma l­
function ex ists .
When the malf unctio n indicator is ill uminated,
the system may not be able to detect or signa l
low tire pressure as intended . TPMS ma lf u nctions
may occur for a variety of reasons, including the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning prope rly . Always c heck the

If the tire pressure monitoring indicator
appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure mon itor­

Care and cleaning
Care and cleaning
General information
Regular, proper care helps to maintain your vehi­
cle's value.
It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The required cleaning and care products can be
obtained from an authorized Audi dealer or au­
thorized Service Facility. Read and follow the in­
structions for use on the packaging .
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health .
- Always store cleaning and care products out
of reach of children to reduce the risk of poi­
soning .
@ For the sake of the environment
- Preferably purchase environmentally-friend­
ly cleaning products.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve­ hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect .
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
Also, wash the underside of your vehicle once road salt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash ­
er, always follow the operating instructions pro­
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at seals on
362
side windows, doors, the hood, the luggage com­
partment lid or the panorama glass roof* or at
tires, rubber hoses, insulating material, the pow­
er top*, sensors* or camera lenses". Keep a dis­
tance of at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows, the panorama glass
roof* and the power top* are closed and the
windshield wipers are off. Follow instructions
from the car wash operator, especially if there
are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutra l shampoo and a soft micro­
fiber cloth.
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois.
