"" .... 0 0 :c ' Your vehicle has also been equipped with a TPM S
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function ex ists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a var iety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: AS, 58
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Fig. 268 Instrument clus ter: indicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires . If the pressure changes in one or more
tires, this is ind icated in the instrument cluster
display with an indicator light
ti] and a message .
Wheels
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:> page 302. The tire pressure mon i­
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:> page 293, fig . 267 .
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- the t ire pressure in one or more tires is too low
- the tire has structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

of situations that could cause a malfunction:
- If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle . This may result
from one or more wheels being installed with­ out wheel sensors or with incompatible wheel
sensors .
- A wheel sensor or another component has
failed .
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains .
- The tire pressure monitoring system is not
available due to a malfunction .
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunction due to
the strong e lectromagnetic field .

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 necessary care products can be obtained
from an authorized Audi dea ler or authorized
Audi Service Facility. Read and follow the instruc ­
tions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store clean ing and care products out
of reach of children to reduce the r isk of poi­
sonin g.
@ For the sake of the environment
- Preferab ly purchase environmenta lly-friend­
l y 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
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, r inse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash­
er , al ways fo llow the operating instructions pro­
vided with the press ure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
306
seals on the side windows, doors, lids or the sun­
roof* or at tires, rubber hoses, insulating materi ­
a l, sensors* or camera lenses* . Keep a distance of
at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozz les or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshie ld wipers are
off . Follow instruc ­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Only use car washes where the vehicle remains
stationary and the washing equipmen t moves
around the vehicle when washing and drying. Car
washes that move the vehicle t hrough the car
wash using a chain are not recommended .
Washing by hand
Clean the vehicl e 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 t he product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse t he ve hicle thoroughly with wate r. Then
clean using a neutral shampoo and a soft micro ­
fiber clot h.
R inse the vehicl e thoroughly again and let it air
dry. Remove any water residue using a chamois.

" N .... 0 0 :c ' & WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
-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 first with a few careful brake
applications.
@ 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.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
-To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight.
-
Care and cleaning
-To reduce the risk of damage, do not wash
the power top with a pressure washer.
-To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
-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 parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved .
@ 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.

When cleaning and caring for individual vehicle
components, refer to the following tables. The
information contained there is simply recom­
mendations. For questions or for components that are
