Wheels
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your 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 tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
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 continuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety 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 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 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 indicated in the instrument cluster
display with an indicator light
[I] and a message.
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 353. The tire pressure moni­
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 344, fig . 2 77.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tires have structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

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 the
354
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 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 and roof* are closed
and the windshield 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.
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 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 .
