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 OCCU­PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢page 219, fig. 181.
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 219, fig. 181.
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
Wheels
be five 1 SO 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 vehi­
c le. Consult this manual to de­
termine how this reduces the
available cargo and luggage load capacity of your vehicle.
.,.Check the tire sidewall
(¢ page 209, fig. 179) 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
cov ers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
i::> Li::,.. ..,.

Wheels
A WARNING
Wheel bolts that are tightened or repaired in­correctly can become loose and result in loss
of vehicle control , which increases the risk of
an accident. For the correct tightening specifi­
cation, refer to
c:> page 231, After changing a
wheel.
- 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 repair
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 traction
on ice and snow.
.., Use winter tires on all four wheels .
.., Only use winter tires that are approved for your
vehicle.
.., Please note that the maximum permitted
speed may be lower with winter tires
c:> .&,.
Your authorized Audi dealer or authorized re­
pai r facility can inform you about the maximum
permitted speed for your tires .
.., Check the tire pressure after installing wheels
c:> page 219.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1S7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re ­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your t ires. This could cause
the tires to heat up too much . This increases
the risk of an accident because it can cause
the tire to burst.
224
- Always adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only win­
ter tires w ith the
& symbol may be permit­
ted.
· Snow chains
Snow chains improve traction in the snow .
.., Only install snow chains on the front wheels.
This applies also to vehicles with all wheel drive* .
.., Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer .
.., Note the maximum permitted speed when driv­
ing with snow chains . Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the
driving in win­
ter road conditions, but also the
braking.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized repair facility to see if you may use snow
chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.S mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and .,.

A WARNING
Using inco rrect snow cha ins or installing snow
chains incorrectly can resu lt i n loss of vehicle
cont ro l, whic h increases the r isk of an acci ­
de nt.
(D Note
Snow chains can dama ge the r ims/whee l cov­

Low aspect ratio tires
Your Au di is factory -equip ped wi th low as pect ra ­
tio ti res. T hese ti res have bee n thoroughly teste d
a nd been se le cted specific ally fo r your model fo r
t he ir su perb pe rformance, road feel and handling
u nd er a variety o f driving conditions . Ask yo ur au­
thor ized A udi dealer for mo re deta ils.
The low aspe ct r atio of these ti res i s indic ated by
a numer al of
55 or les s in th e tire's si ze des igna ­
tion. The nu mera l represen ts the ra ti o of the
tire's sidewall he ight in relation to its trea d width
e x pressed in percentage. Convent io na l tires have
a he ight/w idth ratio of 60 or mo re.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip

What you can do to avoid tire and rim
damage
L ow aspec t rat io t ires ca n be damaged more easi­
l y by impact wi th pot ho les, curbs, gulli es or
r idges on the road, par ticularly if the tire is un­
de rin fla ted.
In o rder to m inim ize the occu rrence o f impact
damage to the t ires of your v ehicl e, we recom-
Wheels
me nd that yo u observe the follow ing p recau ­
t ions:
- Alw ays m aintain r eco m me nded infl ation pre s­
sures. C heck your tire pressure every 2,000
m iles (3,00 0 km) an d ad d air if necessary .
- Dr ive c arefully on road s wi th pot holes, deep
gu llies o r ridges. The impac t from dr iv ing
through or over s uch obstacles can damage
your tires . Impact with a curb may a lso ca use
damage to your tires .
- After a ny impact, imme diate ly inspect yo ur
tires o r have them inspected by the nearest au­
thorized A udi dealer. Rep lace a damaged t ire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire failure .
If you beli eve that a t ire may have
been damaged, re place the t ire as soon as pos­
s ible.
- These ti res may wear more quickly tha n oth ers .
- Please also remember that, wh ile these tires
delive r responsiv e han dling, they may r ide less
comfortably and make mo re no ise than other
c h o ic e s.

Uniform tire quality grading
- Tread wea r
- Traction AA AB C
- Temperature AB C
225

Wheels
Quality grades can be found where applicable on
the tire side wall between t read sho ulder and
maximum sect ion w idth
c::> page 209, fig . 179.
For example: Tr ead wear 200 , Tract ion AA, Tem­
peratu re
A .
All passenger ca r tires must confo rm to Federal
Safety Req uiremen ts in add it ion to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r controlled conditions on a spec ified gov­
ernment test course.
For examp le, a t ire graded 150 would wear one
and one half ( 1 1/2) t imes as well on the govern­
ment course as a tire graded 100 .
The relat ive performance of t ires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations i n driving hab its, service practices and
d iffe rences in road character istics and clima te.
Traction
The traction grades, from highest to lowest, are
AA, A , Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measu red u n­
de r controlled cond it ions on spec ified govern­
ment test su rfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c::> &_ .
Temperature
The temperature grades are A (the highest), B,
a nd C, rep resent ing t he tire's res istance to the
genera tion of heat and its a bility to dis sipate
heat w hen tested unde r controlled cond itions on
a specified indoo r laboratory test whee l.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and red uce tire life,
a nd excessive tempera ture can lead to sudden
tire failure
c::> &. .
The grade C co rresponds to a level of perform­
ance wh ich a ll passenge r ca r tires m ust meet un­
de r th e Federal Motor Vehicle Safety S tandard
No. 109. G rades Band A represent higher levels
226
of pe rformance on the laboratory test whee l than
the minimum required by law .
A WARNING -
The traction grade assigned to th is tire is
based on straight-ahead braking tract ion
tests, and does not include acce lerat ion, cor­
nering, hyd roplaning or peak traction charac­
teristics.
A WARNING
The temperature g rade for th is tire is estab­
lished for a tire that is properly inf lated and
n ot ove rloaded. Excess ive speed, underi nfla­
tion, o r ex cess ive lo adi ng, eithe r separately or
i n comb inat io n, can ca use heat bu ild up and
possible tire failure.
A WARNING
Tempe ratu re grades apply to ti res that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
App lies to vehicl es: wi th tire p ress ure mo nito rin g system
-
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and inflat­
ed to the inflat ion pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different s ize than the size indicated on
the ve hicle placard or t ire inflation pressu re la­
bel, you should dete rm ine the p roper t ire infla­
tion pressu re for those t ires).
As a n added safety feature, your ve hicle has been
equipped with a tire pressure mon itor ing system
( TP MS) that illum inates a low t ire pressure te ll-
ta le w hen o ne or mo re of yo ur ti res is sign ificant -
l y unde r-i nflated. According ly, w hen t he low t ire
pressure te lltale illuminates, you shou ld stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure . Dr iving on a signifi­
cant ly under-inf lated tire causes the t ire 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
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle 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.

If the Tire Pressure Monitoring System
indicator appears
Appl ies to vehicles : wi th t ir e p ress ure mo nito rin g system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 183 Instrument cluster: i ndicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires .
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] 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 228. 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

Emerg enc y ass is tance
There are some restrictions on the use of the
compact spare tire. The compact spare tire has
been designed specifically for your type of vehi­
cle. It must not be swapped with a compact
spare tire from another type of vehicle.
Snow chains
For technical reasons, the use of snow chains on
the compact spare tire is
not permitted .
If you do have to drive w ith snow cha ins and a
front tire f ails, mount the spare whee l with tire
instead of a rear tire. Install the snow chains on
the rear tire and use it to replace the defective
front tire .
A WARNING
-Never use the spare tire if it is damaged or if
it is worn down to the tread wear ind icators.
- If the spare t ire is more than 6 years o ld,
use it only in an emergency and with ex­
treme caut ion and careful driving.
- The spare tire is intended only for tempora­
ry and short-term use.
It should be replaced
as soon as possible with the norma l wheel
and t ire.
- After mounting the compact spare tire, the
tire pressure must be checked as soon as
poss ible. The tire pressure of the compact
spare t ire must be 4.2 bar; otherwise, you
risk having an a cc ident.
- Do not drive faster than 50 mph (80 km/h) .
You r isk having an accident.
- Avoid full-throttle acce lerat ion, heavy brak­
ing, and fast cornering. You r is k having an
a cc ident.
- Never dr ive using more than one spare
wheel and tire. You risk hav ing an accident.
- Norma l summer or winter tires must not be
mounted on the compact spare whee l rim.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive w ith tire chains, the spare
wheel m ust be mounted on the front axle in
the event of a flat in a rear tire. The new ly
available front wheel must then be installed
in place of the rear wheel with the flat tire .
230
Installing the tire chain before mounting
the wheel and tire is recommended.
- Loose items in the passenger compartment
can cause serious personal injury during
hard braking or in an accident. Never store
the spare tire or jack and tools in the pas­
senger compartment .
