Tie-downs
Applies to vehicles: with tie-downs
The Luggage compartment is equipped with four
tie-downs to secure Luggage and other i tems.
Use the tie-downs to secure your cargo properly
<=> page 118, Loading the luggage compartment.
In a coll is io n, the laws of phys ics mean that even
smaller items that are loose in the vehicle w ill
become heavy m iss iles that can cause serious in­
jury. Items i n the vehicle possess energy which
vary w ith vehicle speed and the weight of the
item . Vehicle speed is the most significant factor .
For examp le, in a frontal coll is ion at a speed of
30 mph (48 km/h), the fo rces acting on a 10-lb
( 4 .5 kg) obje ct are abou t 20 times the normal
weight of the item. This means that the we ight
of the item would suddenly be abo ut
200 lbs . (90 kg). Yo u can imagine the injuries
that a 200 lbs. (90 kg) item flying free ly through
t he passenger compartmen t could cause in a co l­
lision like this.
A WARNING
Weak, damaged or improper straps used to
secure items to t ie-downs ca n fa il during hard
braking or in a collision and ca use serious pe r­
sonal i njury.
- Always use suitable mounting straps and
properly secure items to the tie-downs i n
t h e luggage compartment to help prevent
items from shifting or f ly ing fo rward as dan ­
gerous missiles .
- When the re ar seat bac krest is folded down,
always use suitable mounting s traps and
120
-
properly secure items to the t ie-downs in
the l uggage compartment to help prevent
items from flying forward as dangerous mis­
siles into the passenger compartment .
- Never attach a child safety seat tether strap
to a tie-down.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized repair facility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts .
.,.N ew tires do no t yet have the
optimum adhesion properties.
D rive carefu lly and at moderate
speeds fo r the first 350 miles
(500 km) with new tires.
.,. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possib le on all four
wheels.
.,. Do not replace tires individually.
At least replace both tires on the same axle at the same time .
216
.,.A udi recommends that yo u use
Aud i O rig ina l equipment tires . If
you would like to use different t ir es, please note that the ti res
may pe rform differently even if
they are the same size
c:> A -
.,. If you would li ke to equ ip your
vehicle with a tire/rim combina ­
t ion tha t is different from what
was installed at the facto ry, con­
sult with an authorized Audi
dea ler or authorized repa ir facili­
ty before making a purchase
¢ ,&. .
The spare tire* is different from
the regular tires installed on the
vehic le - for examp le, if winter
tires or wide t ires are insta lled -
then only use the spare tire* tem­
porarily in case of eme rgency and
drive carefully wh ile it is in use. It
s h o ul d be rep laced wi th a regular
tire as soon as poss ib le .
On
all wheel drive vehic les, all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
dr ive system is not damaged by
diffe rent tire speeds. For this rea­
son, in case of emergency, only
use a spa re tire* that is the same
circumference as the regular tires . .,.

_& WARNING -
-Only use tire/rim combina­tions 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 6 years old when abso­
lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
Wheels
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 180 Tire profile: Treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
- Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
- Have an authorized Audi dealer
or authorized repair facility
check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.

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

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

w it h them. Remove the whee l cov ers* f irst .
Use coat ed snow c hains.
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.
