•
Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinfla­
tion , or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected . This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow . Winter tires (snow tires) must always be fitted on all four wheels
.
Compatible tire pressure monitoring sensors* must be installed on
all four winter tires for the tire pressure monitoring system* to func­
tion properly ~
page 256.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes . Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to
a depth of 0.157 inch (4 mm) .
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel
~ page 254.
Please always remember that winter tires may have a lower speed
rating than the tires originally installed on your vehicle at the time
it was manufactured . Please see~
page 256, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at which the tires can be driven.
The speed rating letter code(~
page 256) is on the side wall of the
tire
~ page 254.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation, loss of control, crashes and serious _,,

personal injur ies . Have worn or damaged tires replaced immedi­
ately.
• Winter tires have ma ximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which th e winter or other
tire s installed on your vehi cle are rated.
& WARNING
Always adjust your driving to the road and traffic condit ions .
Never let the good acceleration of the winter tire s and all -wheel
d rive tempt you into taking extra risks. Always remember :
• When braking , an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads ,
even winter tires cannot help under black ice conditions.
<£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o not wear as quick ly a nd r educe fuel cons ump tion.•
Snow chains
Sn ow cha ins may be fitte d only to th e fron t whee ls, and o nly to
certain tire sizes . Ask your authorized Audi dealer on which tire
s iz es snow c hains can be used.
If you are going to use snow cha ins, then you must install them on
the front wheels at least.
The s now chains mus t have low-pro file l inks and must not be thicker
than 0. 53 inch ( 13.5 mm), including the lock. Remove wheel
center covers and trim discs before putting snow
chains on y our vehicle =>
(D. For safety reasons cove r caps mus t
then be fitted over the wheel bo lts . These are avai lable from autho ­
r ized Audi deale rs .
& WARNING
Using the wrong snow chain s for your vehi cle or in stalling them
incorre ctly can increase the risk of loss of control leading to
serious personal injury.
• Snow cha ins are available in different sizes . Alw ays make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains .
• Always observe local regulations .
0 Note
• Remove snow c ha ins before driving o n roads not covered with
snow to avoid damaging tires and wearing the snow cha ins down
u n n ecessa ri ly .
• Snow chains, which come into direct contact with the wheel rim,
ca n scratc h or da mage it . There fore, make sur e th at the sn ow cha ins
are suitab ly cove red . Check the position of the snow chains after
dr ivi ng a few yards a nd correct if ne cessary. Foll ow th e instruct io ns
from the snow chain manufacturer when doing so.

& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The s pecified torque for the wheel bolts is 90 ft lb ( 120 N m) with a
to lerance o f± 7,4 ft lb(± 1 0 Nm). Torque whee l bolt s diago nally.
After chang ing a whee l, the torque must be checked as soon as possible with a torque wrench

Low aspect ratio tires
You r A ud i is fac tory-eq uippe d w ith low aspect ra tio tire s. T hese tire s
have been thorough ly t ested and b een se lected specifica lly for your
mod el for thei r su p erb pe rf or manc e, r oad f eel an d ha nd ling under
a variety of driving con ditions . As k your authorized Audi d ealer for
m ore de ta ils.
The low aspect rat io o f th ese t ires is indicated by a numer al of 55 or
less in the t ire's size designation. The numeral rep resents the ratio
o f t he t ire's s idewa ll he ig ht in rel ati on to it s tread w idt h ex pressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
mo re.
The performan ce of low -aspe ct-ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflat ion pressure is regularly checked and ma intained. Tire pres­
sures should be checked at least once a month and always before a
long trip=> page 249, "Checking tire pressure" .
What you can do to avoid tire and rim damage L ow aspect ratio tires can be damaged mo re easily by impact with
po tho les, cu rbs, gull ies o r rid ges o n th e road, particular ly if the t ire
is underinf lated .
I n or der to mini mize th e occurrence of i mpac t da mag e to t he tires

Tire pressure monitoring system *
Applies to vehicles: with tire pressu re mon ito ring system
General notes _J
Each tire, including the spare (if provided), should be checked
month ly when cold and inflated to the inflation pressure recom­
mended 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 pres­
sure label, you should determine the proper tire inflation 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 tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low t ire pressure te llta le i llu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure . Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflation also reduces fue l efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the leve l to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction indi­
cator to indica te when the system is not opera ting proper ly . The
T PMS malfunction indicator is combined with the low tire pressure
t elltale. When the system detects a ma lfunction, the telltale w ill
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
be ab le to detect or signa l low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, inc luding the insta
llation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction telltale after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TP MS to continue to function
proper ly. •
App lies to veh ic les: w ith tire pressure monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitor ing syste m senses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbols appear in the ins trument c luster dis play to alert the d river .
The warning light in the instrument cluster comes on when the
t ire is sig nificantly unde rinflated
~ page 12 .
The warn ing light { also i lluminates in the case of a system
malfunction.
Be aware that tire p ressu re is also dependent on the tempe ra ture of
the tire . For every 18 °F (1 O °Cl increase in tire temperature, tire pres ­
su re increases by about 1 .5 psi (0 .1 bar). The ti re wa rms up wh ile the
vehicle is moving and tire pressure rises. So you should adjust tire pressure only when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all fou r tires sh ould be checked at regular
interva ls, adjusted if necessary, and saved in the proper setting
(recommended pressure)~
page 265.
The tire pressure is shown either on the driver's side B-pil lar or on
the inside of the fuel filler f lap . _..

& WARNING
Always store jacking equipment, spare wheel in the luggage
compartment. Tighten screw for the spare wheel securely. Under
no circumstances should you store the spare wheel or jack and
tools unsecured in the passenger compartment. This could cause
serious personal injury to passengers
in the vehicle in case of a
collision.
• The compact spare tire is for temporary use only and is so
marked on the sidewalls.
• Do not drive at speeds exceeding 50 mph (80 km/hi with the
compact spare wheel mounted. Also rapid acceleration, hard
braking and hard cornering must be avoided to help prevent loss
of vehicle control.
• Any continuous road use of the compact spare tire may result
in tire failure, loss of vehicle control and injury to vehicle occu­
pants.
• Do not put a snow chain on your compact spare tire. Due to the
smaller tire size, the chain will not fit properly and can thus
damage your vehicle. You could also lose the chain, as well as
control of the vehicle .
• If you have a flat front tire in road conditions which require
snow chains, first remove the undamaged rear wheel and mount
the compact spare wheel in its place. Then remove the damaged
front wheel, take the snow chains off it and attach them to the
wheel taken from the rear. This wheel can now be mounted on the
front with its snow chains. Check and adjust tire pressure promptly.
• Never use two or more compact spare tires at the same time.
0 Note
When using the compact spare wheel, note the following: •
After installing the compact spare wheel, the tire inflation pres­
sure should be checked and, if necessary, increased to 60 psi (4 .2
barl.
• The load carrying capacity is marked on the tire sidewal ls and
must not be exceeded .
• After installing the compact spare wheel, make sure that you
remount the flat tire in its storage area properly .
• The compact spare tire should be properly remounted in its
storage area as soon as the standard road tire can be replaced.
• Because the compact spare tire was specifically designed for
your vehicle, it must not be used on any other vehicle . Likewise,
compact spare wheels from other vehic les must not be used on your
vehicle.
• The compact spare tire must not be mounted on any other
wheels, nor must standard tires, snow tires, wheel covers or trim
rings be used with the compact spare wheel. If such use is
attempted, damage to these items or other vehicle components
may occur.
[ i] Tips
Check the inflation pressure of the compact spare tire (60 psi/4 .2
bar) periodically to keep the tire ready for use .•
Wheel change
Before changing a wheel
Observe the following precautions for your own and your
passenger's safety when changing a wheel.
- After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop

& WARNING
•
The actual Gross Axle Weight Rating at the front and rear axles
should not exceed the permissible weights, and their combination
must not exceed the Gross Vehicle Weight Rating.
• Exceeding permissible weight ratings can result in vehicle
damage, accidents and personal injury.
0 Note
• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehicle weight. Always remember that the vehicle's
handling will be affected by the extra load. Therefore, adjust your
speed accordingly.
• Always observe local regulations.•
Dimensions
The specifications refer to the basic model. Differences may occur
depending on the model type and options ordered, for example, tire
sizes.
0 Note
When driving up steep ramps, on rough roads, over curbs, etc. it is
important to remember that some parts of your vehicle, such as
spoilers or exhaust system components, may be close to the
ground. Be careful not to damage them. •
