use a spare tire* that is the same
circumference as the regular
tires.
&_ 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.
Tires and wheels
-Only use tires that are more
than 6 years old when abso lutely necessary and drive
carefully when doing so.
-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 allow enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

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. ..

Tires and wheels
-Have an authorized Audi dealer or authorized Audi Service Facili
ty 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.

Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in. (1.6 mm) high and are
spaced evenly around the tire per
pendicular to the running direc
tion

stall the wheels from the rear
axle on the front axle and vice
versa . This will allow the tires to
have approximately the same
length of service life.
For unidirectional tires, make
sure the tires are installed accord
ing to the running direction indi
cated on the tire sidewall
¢page 288.
Hidden damage
Damage to tires and rims can of
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out
side, drive slowly and carefully to
the nearest authorized Audi deal

cility to have the vehicle inspect
ed .

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe
ty precautions inc:::> page 266,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con
trol.

Please note the important safe
ty precautions regarding tire pressure ¢
page 263 and load
limits ¢
page 266.
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-
266
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 installed 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 150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ
ed as part of the vehicle load.
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 (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas sengers in the vehicle or passen
gers who are heavier than the
standard weights assumed mean
Tires and wheels
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 B-pillar
¢ page 263,
fig. 204.
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to
carry will prevent the vehicle
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 -,..

Wheel bolt s
Wheel bolts must be clean and loosen/t ighten
eas ily.
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
d isassemble them¢.&, .
A WARNING -
Wheel bolts that are t ightened 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 specif i
cation, refer to¢
page 284, After changing a
wheel.
- Always keep the wheel bolts and the
threads in the whee l 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 d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the veh icle's
handling when driving in winter condit ions . Be
cause of the ir construction (width, compound,
tread pattern), summe r tires provide less trac
tion o n ice and snow.
"' Use winter t ires on all fo ur wheels.
"' Only use winter t ires that are approved for your
vehicle.
"' Please note tha t the maximum permitted
speed may be lower with winter tires ¢
_&.. An
authorized Audi dealer o r authorized Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires.
"' Check the tire pressure after installing wheels
¢page 263.
Tires and wheel s
The effectiveness of winte r tires is reduced great
ly when the tread is worn down to a depth of
0.15 7 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re gardless of the rema in ing tread.
A WARNING
=
- Never drive faster than the max imum per
mitted speed for your tires. This could cause
the t ires to heat up too much. This increases
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 ion on black ice.
@) For the sake of the environment
Reinstall summer tires at the app ropr iate
time, beca use they prov ide bette r handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fue l
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, on ly
winter tires w ith the .& symbo l may be per
mitted.
Snow chains
Snow chains improve traction in the snow .
"'On ly install snow cha ins on the front wheels.
This applies a lso to vehicles with a ll w heel
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 dr iv
ing with snow chains. Do not exceed 30 mph (50 km/h) .
Snow cha ins not o nly improve the
driving in win-
ter road condit ions, but also the
braking. Iii>
