Media
General information
There may be different media sources and con-
nections available depending on the vehicle
equipment. For example, you can play media files
using a connected USB drive or connect your mo-
bile devices to the Audi music interface and oper-
ate them through the MMI.
Media and format restrictions: the MMI (includ-
ing the USB storage device connection) was test-
ed with a variety of products and media on the
market. However, there may be cases where indi-
vidual devices or media and audio/video files may
not be recognized, may play only with restric-
tions, or may not play at all.
Restricted functionality: reset the MMI to the
factory default settings if functionality is restrict-
ed > page 213.
Digital Rights Management: please note that
the
audio/video files are subject to copyright pro-
tection.
Files that are protected by DRM and are identi-
fied with the symbol f@ will not play.
Data security: never store important information
on mobile devices. Audi is not responsible for
damaged or lost files and media.
Loading times: the more files/folders/playlists
there are on a storage medium, the longer it will
take to load. To reduce the amount of time it
takes the audio/video files to load, use a storage
medium that only contains audio/video files, and
create subfolders (for example, for each artist or
album).
Additional information: when playing, audio
files are automatically displayed with any addi-
tional information that is stored (such as the ar-
tist, track and album cover). If this information is
not available on the medium, the MMI will revert
to the local Gracenote metadata database or
search online if necessary. See > page 207, On-
line additional data. However, in some cases, the
additional information may not be displayed.

Checking and Filling

Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

A WARNING
— The engine compartment in any vehicle is a
potentially dangerous area. Stop the engine,
switch the ignition off, and allow the engine
to cool before working in the engine com-
partment. Always follow the information
found in > page 221, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.

® Note
Do not continue driving if the coolant expan-
sion tank is empty. Do not add any coolant,
because air could enter the cooling system
and damage the engine. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.

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.

ZA\ 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
— Purchase environmentally-friendly cleaning
products if possible.
— Do not dispose of cleaning and care prod-
ucts 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 vehicle with 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 the
seals on the side windows, doors, lids or the sun-
roof* or at tires, rubber hoses, insulating materi-
al, sensors* or camera lenses*. Keep a distance of
at least 16 inches (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 °C).
Automatic car wash
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield wipers are off. Make sure that
the vehicle is still able to roll during the washing
process in the car wash. Follow instructions from
the car wash operator, especially if there are ac-
cessories 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 downward using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To reduce the risk of damaging the paint when
washing, first remove dust and large particles
from your vehicle. Insects, grease spots, and fin-
gerprints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To re-
duce the risk of damaging the paint surface, do
not use too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft micro-
fiber cloth.
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois.

Z\ WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and

255

Care and cleaning


follow the instructions from the car wash
operator.
—To reduce the risk of cuts, protect yourself
from sharp metal components when wash-
ing the underbody or the inside of the wheel
housings.
— After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in-
creases the risk of an accident. The brakes
must be dried with a few careful brake appli-
cations.

@) Note
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
—To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
—To reduce the risk of damage, do not wash
decorative decals* with a pressure washer.
—To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges, or similar items.
— When washing matte finish painted vehicle
components:
— To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
— Never use protective wax. It can destroy
the matte finish effect.
— Do not place any stickers or magnetic
signs on vehicle components painted with
matte finish paint. The paint could be
damaged when the stickers or magnets
are removed.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
—To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be-
tween the guide rails in the car wash.
—To reduce the risk of damage, compare the
height and width of your vehicle with the
height and width of the inside of the car
wash.
(*) For the sake of the environment
Only wash the vehicle in facilities specially de-
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
Cleaning and care information
When cleaning and caring for individual vehicle
components, refer to the following tables. The
information contained there is simply recommen-
dations. For questions or for components that
are not listed, consult an authorized Audi dealer
