Storing new tire pressures
Applies to: S8 plus
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring .
.. Check the tire pressures in all wheels.
1> If necessary, correct the tire pressure according
to the spec ificat ions on the sticker on the driv ­
er's door ~
page 291 . Only correct the press ure
in tires whose tempera tu re is approx imately
the same as the amb ient temperature.
If the
tempera ture of the tire is highe r than the ambi­
ent a ir temperat ure, the tire pressure must be
increased approximately 3 PSI (0,2 bar) above
the va lue on the sticker.
.. Switch the ignition on.
.. Se lect :
I CARI funct ion button > Car systems >
T ire pr essure monitoring > Store tire pres­
s ure s.
After stor ing, the tire pressure mon itor ­
ing system measures the c urrent tire pressures
and stores them as the new specified p res­
s ur es .
.. If the changed tire press ures are not displayed
in t he Infotainment system, dr ive the veh icle
for approximate ly 10 minutes so that the sen ­
sor signal from the whee ls is received again .
During this adap tat ion phase, --,-- is disp layed
for pressure and temperature and the Tire Pres ­
sure Monitoring System is only partially availa­
b le: it only warns you if one or more of the tire
pressures is/are under the m inimum permitted
va lue. If this is the case, the

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 dealer 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 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
306
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 °C).
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.
Only use car washes where the veh icle remains
stationary and the washing equipment moves
around the vehicle when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
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. ..,..

0 co .... N ,..... 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.
(D 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.
