circumference as the regular
tires.
A_ WARNING -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
- Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
254
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents .
-If you install wheel covers on the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.

Checking/correcting tire
pressure
•Check the tire pressure at least
once per month and also check it
before every long drive.
•Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
•Check the label ¢
fig. 191 for
the correct tire pressure based
on vehicle load.
•Correct the tire pressure if nec ­
essary .
•Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain­ ment system ¢
page 265.
•Check the pressure in the emer­
gency tire*/spare tire*. A lways
maintain the maximum temper­
ature that is specified for the
tire.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop .
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci-
ty") with an assumed weight of ..,

2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 256, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the "XXX" amount
equals 1400 lbs and there will
be five 150 lbs passengers in
your vehicle, the amount of available cargo and luggage
load capacity is 650 lbs
(1400-750 (5
X 150) = 650 lbs)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­ ceed the available cargo and luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your ve-
260
hicle. Consult this manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi­
cle.

(¢ page 246, fig. 188) to deter­
mine the designated load rating
for a specific tire.
· Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them
¢ &..
_8. WARNING
-Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
¢ page 2 78, Finishing.
- Always keep the wheel bolts and the threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident .

¢ page 256 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1 57 in (4 mm) . The character istics of winter
tires a lso decrease great ly as t he tire ages, re­
ga rdless of the remaining tread .
_& WARNING
-Never dr ive faste r than the maxim um per­
mitted speed for your t ires. This cou ld cause
the tires to heat up too much . Th is increases
the risk of an acc ident because it can cause
the tire to burst.
- Always adapt yo ur dr iv ing to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the approp riate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption .
You can also use all season tires instead of
w inter t ires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
-
Snow chains no t only imp rove the d riving in w in­
ter road conditions, but also the braking.
Wh eel s
... On ly install snow chains on the front wheels.
This applies a lso to vehicles with a ll wheel
drive* .
... Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
... Note the maximum speed of 30 mph (SO km/
h) . Note the local regulations .
Use of snow cha ins is only permitted with certa in
rim/tire comb inat ions due to technical reasons .
Check with an authorized Audi dealer or author­
i zed Audi Se rvice Facility to see if you may use
snow c hains.
You must remove the snow chains on roads with­ out snow . O therwise, you co uld impair driving
ability a nd damage the t ires .
_& WARNING

Low aspect ratio tires
Your Audi is factory-equ ipped with low aspect ra­
tio t ires . These tires have been thoroughly tested
and been selected spec ifically for your model for

Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temperature
The temperature grades are A (the highest), B ,
and
C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c:> .& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109 . Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight -ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Wheels
Tire pressure monitoring system
ill 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 ind icated 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
proper ly .
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor ­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
disp lay with an indicator light
RR and a message.
If only one tire is affected , the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load pressure) or after changing or replacing a tire on
your vehicle ¢
page 265 . The tire pressure moni­
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 256, fig.191.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage .
- the tire was replaced or the tire pressure was
changed and it was not stored¢

short period of time , drive to an authorized A udi
dealer or authorized Audi Service Facility immedi ­
ate ly to have the ma lfunction corrected.
_& WARNING
-If the tire pressure indicator appears in the
disp lay, reduce your speed immediately and
avoid any hard steering or brak ing maneu­
vers. Stop as soon as poss ible and check the
tires and their pressure .
- The driver is responsible for maintain ing the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain cond it ions (such as a sporty
driving style, w inter condit ions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not perm itted can lead to
vehicle damage or accidents.
(D Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC mal­
function.
- Us ing snow chains may result in a system
ma lfunction.
- The tires w ith the identification "AO"

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 necessary care products can be obtained
from an authorized Audi dealer or authorized
Audi Service Facility. Read and follow the instruc­
tions for use on the packaging.
A 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
- Preferably purchase environmentally-friend­ ly cleaning products.
- Do not dispose of leftover cleaning and care
products 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 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 vehicles with a pressure
washer, always follow the operating instructions
provided with the pressure washer. This is espe­
cially important in regard to the pressure and
spraying distance . Do not direct the stream of
water directly onto seals for the side windows,
266
doors, luggage compartment lid or hood or onto
the tires, rubber hoses, insulating material, sen­
sors* 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 nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °().
Automatic car washes
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.
Washing
by hand
Clean the vehicle 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 the product using a microfiber cloth. To
avoid 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 .
A WARNING
-
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
