150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle .
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side 8-pillar
¢ page 256,
fig. 190.
&_ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carry ing more weight than
your vehicle was designed to
carry will prevent the vehicle
Wheels
from handling properly and
increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­ tal load being transported
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload­ ed.
Steps for Determining Correct Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD .,.
259

Wheels
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 256, fig. 190.
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.
~check the tire sidewall
(¢ 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 .
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions . Be-
cause of their construction (width, compound, ..,.

tread pattern), summer tires provide less trac­
tion on ice and snow.
.,. Use w inter tires on a ll fo ur wheels.
.,. Only use win ter tires that are approved for your
vehicle.
... Please note that the maximum permitted
speed may be lower with winter tires ¢,& .An
authori zed Aud i dealer or authori zed Aud i Serv­
ice F acility can inform you about the maximum
permitted speed for your tires .
... Check the tire pressure after installing wheels
¢ 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
Using incor rect snow chains or install ing snow
ch ains incor rec tly c an resu lt in loss of veh icle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
- Us ing snow chains that add more tha n O.S3
in (13,S mm) of height can severe ly damage
the whee l housings and other vehicle com­
ponents.
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode ¢

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
the ir superb performance, road feel and handl ing
under a var iety of dr iv ing condit ions. Ask your au-
thorized Audi dea le r fo r more details . .,.
261

Wheels
The low aspect ratio of these tires is i ndicated by
a numeral of
55 or less in the tire's si ze designa­
tion. The numera l rep resents the rat io o f the
tire's sidewall he ight in relat ion to its tread width
expressed in percentage . Conventional tires have
a height/w idt h rat io of 60 o r more.
The performance of low -aspect-ratio tire s is par ·
ticularly sensitive to improper inflation pres­
sure.
It i s therefore important that low aspect
ratio tires ar e inflat ed to the specifi ed pr essure
and that the inflation pre ssure is regularly
checked and maintained . Tire pre ssure s should
be checked at le ast once a month and always
before a long trip¢
page 256.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi­
ly by impact wi th potholes, cu rbs, g ullies or
ridges on the road, pa rt ic ul arly if the tire is un­
derinflated .
I n order to minim ize t he oc currence of impac t
d a mage to the t ires of your ve hicle, we recom ­
mend that you ob5erve the following precau­
tions:
- Always mai nta in recommended inf lation pres ­
s ur es . Che ck your tire p ress ure every 2,000
miles (3, 000 km) and ad d air if necessary .
- Drive caref ully on roads with potho les, deep
gull ies or r idges . The im pact from d riving
th rough or ove r su ch obs tacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
-A fter any impact, immediately inspect your
ti res or have them inspected by the nearest au ­
thori zed Audi dea ler. Replace a damaged tire as
soon as possib le.
- Inspect yo ur tires every 2,000 miles (3,000 km)
for damage and wear. Damage is not always easy to see. Damage can lead to loss of air and
underinflation, which cou ld eventually cause
ti re failure . If you believe that a tire may have
been damaged, re place the t ire as soon as pos­
s ible.
- T hese tires may wear more qu ick ly than othe rs .
- Please a lso remember t hat, w hile these tires
deliver responsive handling, they may r ide less
262
comforta bly and make more noise than o ther
choices .
Reduced performance in winter/cold season
condition s
All tires are des igned for certain purposes . The
l ow aspect ratio , ultra h igh performance tires
o rigina lly installed on your vehicle are intended
for maximum d ry and wet road perfo rmance and
handling. They a re not suitable for co ld, snowy or
i cy weather conditions . If you drive under those
c ircumstances, you should equip you r vehicle
with all-season o r winter tires, which offer better
t ra ct ion unde r th ose condi tio ns. We suggest yo u
u se the recommen ded snow or a ll-season tires
spe cified for your vehicle, o r th e ir equiv alent.

Uniform tire quality grading
- Tr ea d wea r
- Tr actio n AA ABC
- T empe ratu re ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
max imum section width
¢ page 246, fig . 188.
For example : Tread wear 200 , Traction AA , Tem­
perature
A .
All passenge r ca r tir es must conform to Federal
Safety Req uirements in a ddition to these grades.
Tread wear
The tread wear grade is a compa rative rating
based on the wea r ra te o f the tire w hen tested
u nder con trolled cond itions on a specified gov ­
ernment test course .
Fo r example, a tire g raded 150 wou ld wea r one
a n d one half (1 1/2) times as well o n the govern ­
ment cou rse as a t ire graded 100.
The re lative pe rformance of tires depends upon
t h e ac tual cond itions of the ir use, however, and
m ay dep art significan tly from the no rm due to
variations in driv ing habi ts, service pract ices and
diffe rences in road characteristics and climate. ..,.

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 .,.

Wheels
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¢

page 265. If the indica­
tor light does turn off or turns on again after a
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.

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 .

- 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 brak ing effect
may be delayed due to mo isture on the
brake rotors or ice in the w inter . This in­
creases the risk of an acc ident. The brakes
must be d ried fi rst w ith a few careful b rake
applications.
(D Note
- If you wash t he vehicle in an automatic car
