2020 AUDI R8 COUPE warning light

Wheels

— If wheels with new wheel sensors are used

Z\ WARNING
— The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in-
flated to the correct pressure.
— Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, increas-
ing the risk of an accident.
— A tire with low pressure flexes more. This
heats the tire up too much. This could cause
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.

G) 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.
— For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

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 254, fig. 194. 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 > Service & checks > Tire pressure monitor-
ing > Store tire pressure > Yes, store now. Af-
ter storing the tire pressures, the tire pressure
monitoring system measures the current pres-
sures 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.

ZA\ WARNING
Read and follow the important information
and notes > page 261.
Malfunctions
Applies to: vehicles with tire pressure monitoring system

If the tire pressure monitoring system is not
available, the is indicator light appears in the
instrument cluster display along with the mes-
sage Tire pressure: malfunction! See owner's
manual.
If the iis 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 system malfunc-
tion. The following are examples of situations
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 is indicator light stays on, drive

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 remain on the vehicle,
the more the surface may 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 anda
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 direct the stream of water di-
rectly onto seals for the side windows, doors, lug-
gage compartment lid or engine compartment
lid, or onto the tires, rubber hoses, insulating
material, sensors” or camera lenses”. Keep a dis-
tance 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 wash
Spray off the vehicle before washing.
Make sure that the windows 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.
Only use car washes where the vehicle 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 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.
