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

venience

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.

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.

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasing ly more and more diff i­
cult to replace vehicle light bulbs s ince in many
cases, othe r parts of the car must fi rst be re­
moved before you are able to get to the bu lb .
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, parts must be
correct ly taken apart and then properly put back
together to he lp prevent breakage of parts and
380
long term damage from water that can enter
housings that have not been properly resealed.
Fo r you r safety, we recommend that you have
you r autho rized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bu lbs and the expertise.
Ga s di sc harg e la mp s (Xe non ligh ts):
Due to the h igh electr ical voltage, have the bulbs
rep laced by a qualified technician . Headlights
with Xenon light a re identified by the high volt­
age sticker.
L ED headlight s*
LED headlights require no maintenance. Please
contact your authorized Audi dealer if a bulb
needs to be replaced.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
-Bulbs are pressurized and can explode when
be ing changed. Potent ial r isk of injury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening injuries
can result from improper handling of the
high-vo ltage portions of such lamps!
-Only your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps . There are parts with
sharp edges on the openings and on the bulb holders that can cause serious cuts. If
you are uncerta in about what to do, have
the work performed by an authorized Audi
dea ler or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work.
(D Tips
-If you still prefer to replace the light bulbs
yourself, be aware that the engine compart­
ment is a hazardous area to work
i n c:> & in
Working in the engine compartment on
page 330 .
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb .
