Storing new tire pressures
Applies to: vehicles with tire pressure monitoring system
The tire pressure specifications must be stored
correctly for the tire pressure monitoring system
to function reliably.
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam-
ple due to a change in load or when new sensors
are installed.
> Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci-
fied values and are adapted to the load
=> page 330, fig. 260. Only correct and store
the pressure in tires whose temperature is ap-
proximately the same as the ambient tempera-
ture. If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximately
3.0 PSI (0.2 bar) above the value on the sticker.
» Switch the ignition on.
> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire
pressure > Yes, store now. After storing the tire
pressures, the tire pressure monitoring system
measures the current pressures while driving
and stores them as the new specified pressures.
> If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximately 10 minutes so that the sen-
sor signal from the wheels is received again.


During this adaptation phase, --.-- is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available. It only provides a warning if one or
more tire pressures is below the minimum per-
mitted specified pressure.
If the @ indicator light turns on and the mes-
sage Tire pressure: wheel change detected.
Please check all tires and store pressures in
MMI also appears, the system has detected that
the position of the sensors has changed because
of a tire rotation, or that new sensors were instal-
led. Store the new tire pressures.

ZX WARNING
Read and follow the important information
and notes > page 339.
Malfunctions
Applies to: vehicles with tire pressure monitoring system

If the tire pressure monitoring system is not
available, the a indicator light appears in the
instrument cluster display along with the mes-
sage Tire pressure: malfunction! See owner's
manual.
If the ia indicator light appears after switching
the ignition on or while driving and the @ indi-
cator light also blinks for approximately one mi-
nute and then stays on, there is a system mal-
function. The following are examples of situa-
tions that could cause a malfunction:
— If the message appears at the end of the adap-
tation phase, the system may not detect one or
several of the wheel sensors necessary for pres-
sure monitoring. This may result from one or
more wheels without wheel sensors or with in-
compatible wheel sensors being installed.
—Awheel 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 electromagnetic field.
The ia indicator light and the message turn off
once the tire pressure monitoring system is avail-
able again. If you cannot correct the malfunction
and the ia indicator light stays on, drive imme-
diately to an authorized Audi dealer or author-
ized Audi Service Facility to have the malfunction
repaired.

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 seals on
342
side windows, doors, the hood, the luggage com-
partment lid, or the panoramic 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).
Plug-in hybrid drive: do not direct the stream of
water towards the wall mount clip*.
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, the panoramic 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.
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. >

ZA\ WARNING
—To reduce the risk of accidents, only wash
the vehicle when the ignition is off and fol-
low the instructions from the car wash oper-
ator.
—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.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.

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, 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.
— 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.
