u. co .... N
" N .... 0 0 :c ' 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.
Description
Applies to: 58 plus
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by
radio frequency.
The Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infota inment system
c:> page 303 . It also
compa res the current tire pressures with the
stored tire press ures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
c:> page 304.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures.
- Every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replac ing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
c:> page 304.
A WARNING
-The tire pressure mon itor ing system assists
the driver in monitoring tire pressures. The
dr iver 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.
T his cou ld result in serious damage to the
t ir e and even cause the tire to burst, in­
creasing the risk of an accide nt.
Wheels
-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 acci­
dent.
- The Tire Pressure Monitoring System does
not warn you of damage or defects in the
tire construct ion that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
@ For the sake of the environment
Low tire pressure increases fuel consumption
and tire wear.
(D Tips
-The pressure of the spare t ire* is not mon i­
tored.
- If tires are replaced, the sensors/va lves do
not need to be removed or replaced. Just re­
placed the valve stem and, if necessary, the
valve and the whee l electronics . If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility.
Displaying tire pressures/temperatures
Applies to: 58 plus
Requirement: the ignition must be switched on.
.. Select: the I CAR! funct ion button > Car systems
> Service & control > Tire pressure monitor >
Display tire pressure .
The current tire pressures are shown in green and
yellow numbers in the Infotainment system:
-Green: the current tire pressure and the spec i­
fied tire pressure are approx imately the same .
-Yellow: the current tire pressure is too low
compared to the specified tire pressure .
The specified tire pressure is the last tire pres ­
sure that was stored
c:> page 304 .
Note that the tire pressure also depends on the
temperature of the tire . The tire pressure in­
creases as the engine becomes warmer while
driv ing.

in t ires whose tempe rature is appro ximate ly
the same as the ambient tempera ture. If the
tempe rature of the tire is higher than the ambi­
ent air tempe rature, the t ire pressure must be
i n creased approxim ate ly 3 PSI (0 ,2 ba r) above

sonin g.
@ For the sake of the environment
- Preferab ly purchase environmenta lly-friend­
l y 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
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, r inse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash­
er , al ways fo llow the operating instructions pro­
vided with the press ure 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 ­
a l, 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 nozz les 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 windshie ld 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 vehicle remains
stationary and the washing equipmen t moves
around the vehicle when washing and drying. Car
washes that move the vehicle t hrough the car
wash using a chain are not recommended .
Washing by hand
Clean the vehicl e 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 t he product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse t he ve hicle thoroughly with wate r. Then
clean using a neutral shampoo and a soft micro ­
fiber clot h.
R inse the vehicl e thoroughly again and let it air
dry. Remove any water residue using a chamois.

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.
@ 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.
