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 ..,

a, a, ... N
" N ... 0
" V, a:,
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, ..,.

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.

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¢

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.
- The tires w ith the identification "AO"

nated mou nting point .
• Align the vehicle jack* so the arm @engages in
the designated mounting point in the side sill
and the base @lies flat on the ground. The
base @must be direct ly under the mounting
point @.
• Continue raising the vehicle jack* until the
wheel lifts off the ground slightly.
A WARNING
- Make sure the vehicle jack* is stable. There
is a risk of injury when the ground is slick or
soft, because the vehicle jack* could slide or
sink.
- Only raise your vehicle w ith the vehicle jack*
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi­
cle can slide and cause injury .
- Pos ition the vehicle jack* only at the desig­
nated mounting points on the side sill and
align the jack . Otherwise, the vehicle jack*
co uld slip and cause an injury if it does not
have sufficient hold on the vehicle.
- To reduce the risk of an accident, never start
the engine when the vehicle is raised.
