Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap
proach the curb at an angle.
~ Have faulty tires or rims re
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom
mends using winter tires dur
i ng the winter months. Low
temperatures significantly de crease the elasticity of summ
er tires, which affects traction
328
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi
tions. The surface of the r ims
does not have sufficient corro
sion protection for th is and
could be permanently dam
aged by road salt or similar
substances.

.&_ 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 in
c::> page 339,
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.
-Incorrect tire pressure in
creases tire wear and has a negative effect on driving and
braking behavior, which in
creases the risk of an accident .

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 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
340
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

A 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
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 bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily .
Rims
Rim s with a bolted r im 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 ¢_&. .
..&, 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 35 7, 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 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,
tread pattern) , summer tires provide less trac
tion 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
¢ _&. .An
authorized Audi dealer or authorized Audi Serv
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
¢ page 336.

The effectiveness of winter tires is reduced great
ly when th e tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re
gardless of the remaining tread.
'
..&, WARNING
- Never drive faster than the maximum per
mitted speed for your tires. 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 .
- 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
consumption.
(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
winter tires with the
& symbol may be per
mitted.
Snow chains
-
Snow chains not only improve the driving in win
ter road conditions, but also the braking.
.. 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 after driving a few feet, if necessary . Fol
low the instructions from the manufacturer .
.,. Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.

label, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a t ire pressu re monitoring system
(TPMS) that illuminates a low tire press ure te ll
tale when one or more of your tires is significant l y under- inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a s ignifi
cantly under- inflated tire causes the tire to ove r
h eat and can lead to t ire failure. Unde r-inflation
a lso reduces fuel efficiency and tire tread life,
and may affec t the vehicle's handling and stop
p ing ability .
P lease note that the TPMS is not a substitute for
p roper tire maintenance, and i t is the d rive r's re
sponsib ility to ma inta in cor rec t tire p ressure,
even if under-inflation has not reached the leve l
to trigger illumination of the TPMS low tire pres
sure tellta le .
Your veh icle has also been eq uipped w ith a TPM S
mal funct ion indicator to indicate when the sys
tem is not operating properly . The TPMS ma l
function indicator is combined with the low tire
pressure tellta le. When the system detects a
malfunct ion, the telltale will flash for approxi
mately one minute and then remain cont inuously
i l lum inated . This sequence will continue upon
subseq uent ve hicle start-ups as long as the ma l
function ex ists .
When the malfunct ion indicator is illuminated,
the system may not be ab le to detect or signal
low t ire press ure as intended. TPM S malf unctions
may occur for a var iety of reasons, including the
i nstalla tion of replacement o r alte rnate t ires o r
wheels o n the vehicle that prevent the TPM S
from func tioning properly. Always chec k the
TPMS malfunction telltale afte r rep lacing one or
more tires or whee ls on your ve hicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to cont inue to function
properly.

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diffi
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apa rt and then properly put back
together to help prevent breakage of parts and
