the tread to separate and even cause the tire
to burst, increasing the risk of an accident.
— The tire pressure monitoring system does
not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu-

larly.
Note that the tire pressure also depends on the
temperature of the tire. The tire pressure increas-
es as the engine becomes warmer while driving.

Z\ WARNING
Read and follow the important information
and notes > page 339.

@) Tips
— If tires are replaced, the sensors and valves
do not need to be removed or replaced. Only
replace the valve stem and, if necessary, the
valve and the wheel electronics. If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility.
— An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authorized Audi Service Facility.

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. >

@) Note
When removing or installing the wheel, the
rim
could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
G) Tips
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.
— Pull the reversible blade from the screwdriv:
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
— When mounting tires with unidirectional
tread design make sure the tread pattern is
pointed the right way > page 356.
— The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
356
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be-
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in-
tended for use in a specific direction, please note
the following:
— The direction of rotation is marked by an arrow
on the side of the tire.
— If the spare tire has to be installed in the incor-
rect direction, use the spare tire only tempora-
rily since the tire will not be able to achieve its
optimum performance characteristics with re-
gard to aquaplaning, noise and wear.
— We recommend that you pay particular atten-
tion to this fact during wet weather and that
you
adjust your speed to match road condi-
tions.
— Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec-
tional tire.
Notes on wheel changing
Please read the information > page 326 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
— Check the tire pressure on the spare immedi-
ately after installation.
— Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos-
sible by your authorized Audi dealer ora
qualified service station.
— With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lbs (120 Nm).
