General information
~check your tires regularly for
damage (punctures, cuts, crac ks
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.
(D 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
214
and braking ability. If summer
tires are used in very cold tem­ peratures, 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 rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or similar
substances.
Tire designations
Fig. 168 Tire specification codes on the
sidewall of a tire .,_

Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo­
meters) at low speeds in the three
hour period before the tire pres­
sure is measured or adjusted.
Curb weight
means the weight of a motor ve ­
hicle with standard equipment in­
c luding the maximum capacity of
fuel, oil, and coolant, air condi ­
tioning and add itional weight of
optional equipment.
E xtra load t ire
means a tire designed to operate
at higher loads and at higher in -
Tires a nd whe els
flation pressures than the corre­
spond ing standard tire. Extra load
tires may be identified as "XL",
" xl", "EXTRA LOAD", or "RF" on
the sidewall.
Gross A xle Weight R ating
( " GAWR")
means the load -carrying capacity
of a single axle system, measured
at the tire-ground interfaces .
Gross Vehicle Weight Rating
(" GVWR ")
means the maximum total loaded
weight of the vehicle.
Groove
means the space between two ad­
jacent tread ribs.
Load rating (code )
means the maximum load that a
tire is rated to carry for a given in ­
flation pressure . You may not find
this information on all tires be­ cause it is not required by law.
Ma ximum load rating

-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important
safety precautions in
¢ page 22 7, 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 increas­
es tire wear and has a negative

behavior, which increases the
risk of an accident.
Replace lost valve caps to re­
duce the risk of damage to the
tire valves .
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(1) Tips
Audi recommends using the
tire pressure specified for a nor­mal load
¢ table on page 226
or for a full load when the vehi­
cle is partially loaded.
Make sure that the tire designa ­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table .
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

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
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
Gro ss Vehicle We ight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
Tires and wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in ­
tended to carry ("seating capac i­
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 Ax le Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two ax les.
T he 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 vehic le (inc luding
the weight of a trai ler 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 we ights assumed mean
that less weight can be carried as luggage.

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n 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 a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen 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 a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d
230
'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r 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
b efor e a long trip
Q page 224 .
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
r idges on t he road, pa rti cularly if th e tire is un ­
der i nflated.

Tires and wheels
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109 . Grades Band A represent higher levels
of pe rformance on the laboratory test wheel than
the minimum required by law .
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat ­
ed .
Tire pressure monitoring
system
CD General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat ­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label.
(If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant ­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
232
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire 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 t ire
pressure tel ltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start -ups as long as the ma l­
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 t ires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly .

Bulbs
Replacing light bulbs
For your safety , we recommend that you have
your authorized Audi dealer replace burned out
bulbs for you.
It i s becoming increasingly more and more diffi­
cu lt to replace vehicle light bulbs s ince 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, and pa rts
must be correctly taken apart and then properly
put back together to help prevent breakage of
