Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire
inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a Low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low
tire pressure as intended. TPMS malfunctions
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.
Applies to: vehicles with tire pressure monitoring system
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 Infotainment system while driving
=> page 234. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored > page 234.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 235:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a tire
— If wheels with new wheel sensors are used

ZX WARNING
—The tire pressure monitoring system assists
the driver in monitoring tire pressures. The [>

233

Wheels


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.
—Atire 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.

(i) 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.
— The system complies with United States FCC
regulations and ISED regulations
=> page 267.
Displaying tire pressures and temperatures
Applies to: vehicles with tire pressure monitoring system
Requirement: you must be driving the vehicle.

> Select in the Infotainment system: [MENU] but-
ton > Service & checks > Tire pressure monitor-
ing > Display tire pressure.

The current tire pressures are shown in green,
yellow or red numbers in the Infotainment sys-
tem:
— Green: the current tire pressure and the speci-
fied tire pressure are approximately the same.
234
— Yellow: the current tire pressure is lower than
the specified tire pressure.
— Red: the current tire pressure is much lower
than the specified tire pressure.
The specified tire pressure is the last tire pres-
sure that was stored > page 235.
Note that the tire pressure also depends on the
temperature of the tire. The tire pressure in-
creases as the engine becomes warmer while
driving.

ZA\ WARNING
Read and follow the important information
and notes > page 233.
@ Tips
The tire pressure or temperature is not dis-
played while the vehicle is stationary and in
adaptation mode. Dashes --.-- are shown in
place of the pressure and temperature.
Tire pressure loss
Applies to: vehicles with tire pressure monitoring system

If the @ indicator light turns on, the pressure in
at least one tire is too low or new sensors were
not adapted:
The indicator light turns on after turning the
ignition on
The tire pressure is too low compared to the
specified pressure.
> Check and store the tire pressure(s) the next
time it is possible > page 235.
The indicator light turns on while driving
Wheels with new sensors were not adapted or
the tire pressure has reached a critical level com-
pared to the specified pressure.
> Avoid unnecessary steering and braking maneu-
vers.
> Adapt your driving style to the situation.
> Stop as soon as possible and check the tire(s).
> If it is possible to continue driving, see an au-
thorized Audi dealer or authorized Audi Service
Facility immediately and have your tire(s) re-
paired or replaced if necessary.

ZA WARNING
Read and follow the important information
and notes > page 233.
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 224, fig. 178. 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.
tire pressure: wheel change detected. Please
check all tires and store pressures in MMI
If the indicator light turns on and the message
appears, the system has detected that the loca-
tion of the sensors has changed due to a wheel
replacement, or new sensors have been installed.
Store the new tire pressures.

Z\ WARNING
Read and follow the important information
and notes > page 233.
Malfunctions
Applies to: vehicles with tire pressure monitoring system

a Tire pressure: malfunction! See owner's
manual
If the is 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, then there is 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 iis 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.

ZX WARNING
— Using cleaning and care products incorrectly
can be dangerous to your health.

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 direct the stream of water di-
236
rectly onto seals for the side windows, doors,
luggage compartment lid, or hood, or onto the
tires, rubber hoses, insulating material, sensors”,
or camera lenses*. Keep a distance of at least 16
inches (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 and power top* are
closed and the windshield wipers are off. Make
sure that the vehicle is still able to roll during the
washing process in the car wash. 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.
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. >

Care and cleaning


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 retract the extendable rear
spoiler* if necessary, and fold the exterior
mirrors in to reduce the risk of damage.
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.
