8,_ 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.
Wheels
-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.
Tire wear/damage

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 Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..

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
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard
(tire inflation pre ssure label)
¢ page 221, fig. 192.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
"XXX" kilograms or " XXX"
pounds shown on the sticker
¢ page 221 , fig. 192 .
4. The re sulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals 1400 lbs. and there will
226
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
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
hicle. Con sult this manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle .
~check the tire sidewall
(¢ page 211, fig. 190) to deter­
mine the designated load rating
for a specific tire.

\.J ' and a special procedure. You must not repair or
disassemble them ¢.&. .
A 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 acc ident. For the correct tightening specifi ­
cation, see ¢
page 244, 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 r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be­
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
... Use w inter t ires on all fo ur wheels .
... Only use winter t ires that are approve d for your
v ehicl e.
... Please note that the maximum permitted
speed may be lower with winter tires¢.&_ . An
authorized Aud i dealer or au thori zed Aud i Serv­
ice Fac ility can inform you about the maximum
permitted speed fo r your tires .
... Check the tire press ure after installing wheels
¢page 221.
The effectiveness of winter tires is reduced great­
l y when the tread is worn down to a depth of
0 .1 57 in ( 4 mm). The character ist ics of winter
tires a lso de crease great ly as the tire ages, re­
ga rdless of the remain ing tread.
WARNING
- Never drive faster 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
Wh eel s
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract io n on black ice.
@ For the sake of the environment
Reinsta ll summer tires at the app ropr iate
time, beca use they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fue l
consumpt io n.
(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, on ly
winter tires w ith the
& symbo l may be per­
mitted .
Snow chains
Snow ch ains not o nly improve t he d riv in g in win ­
te r road condit ions, bu t also the braking .
... On ly install snow cha ins on the fron t wheels .
Th is applies a lso to vehicles with a ll w heel
drive * .
... Check and correct the se ating of the snow
chai ns after driving a few feet, if necessary . Fol ­
low th e instructions from the manufacturer.
... Note the maximum speed of 30 mph (SO km/
h). Note the local regula tions .
U se of snow cha ins is only permitted with certa in
rim/tire combinat ions due to technical reasons .
Check with an autho riz ed Audi dealer or author­
i z ed Audi Service Facility to see if you may use
snow c hains .
Yo u m ust remove the snow chains on roads with­
o ut snow . Otherw ise, you co uld impai r dr iving
