A WARNING
-If the brake fluid level is below the MIN
marking, it can impair the braking effect
and dr iving safety, which increase the risk of
an accident. Do not cont inue driving . See an
authorized Aud i dealer or autho rized Audi
Service Facility for assistance.
- If the brake fluid is o ld, bubbles may form
in the b rake system du ring heavy b raking.
This would impair brak ing performance and
driving safety, which increases the risk of an
accident.
- T o ensure the brake system functions cor­
rectly, only use brake fluids t hat comply
with VW standard 501 14 or
FMVSS-116 DOT 4.

& 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-

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 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.

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.
Treadwear indicator
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
¢ fig . 148 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators .
The tires have reached the mini­ mum tread depth

wear evenly. To rotate the tires,
install the tires 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 202.
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
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety. ,..

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 in¢
page 183,
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

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

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 in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of.,.
183

Wheels
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 1 SO 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
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
184
driver's side B-pillar ¢ page 181,
fig. 149.
~ 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 -including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Wheels
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 accident. For the correct t ightening specifi ­
cation, see ¢
page 199, 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 l ess 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
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 181.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A 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
186
-
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 a ll 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 permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13 .5 mm) in height, includ­
ing the chain lock.
You must remove the snow chains on roads with­
out snow. Otherwise , you could impair driving
ability and damage the tires .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­ i z ed Audi Service Facility to see if you may use
snow chains.

& WARNING
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent.
(D Note
Snow chains can damage the rims/wheel cov­
ers * if the chains come into direct contact
wit h them . Remove the wheel covers * first .
Use coated snow chains.
Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires . These t ires have been thoroughly tested
and been se lected specifica lly for you r model for
the ir supe rb performance, road feel and handling
u nder a va riety of d riving conditions. As k yo ur au­
thor ized Audi dealer for mo re de tails.
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire's size desig na­
tion . The numera l rep resents t he rat io of the
tire's sidewall he ight in rela tion t o its tread w idth
expressed in percen tage. Conventional t ires have
a height/w idth ratio of 60 or more .
The performan ce of low -aspect-r atio tire s is par­
ticularly sen sitiv e to impr oper infla tion pre s­
s ure . It is therefore important that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and ma inta ined . Tire pre ssure s should
be checked at least once a month and alwa ys
before a long trip
c> page 181.
What you can do to avoid tire and rim damage
Low aspect rat io tires can be damaged more easi­
ly by impact with potholes, curbs, gul lies or
ridges on the road, pa rticularly if the tire is un­
de rinflated .
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom­
mend that you observe the follow ing precau­
tions:
Wh eel s
-Always maintain recommended inflat ion pres ­
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads wit h potholes, deep
gu llies or ridges . T he impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
-After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not a lways
easy to see . Damage can lead to loss of a ir and
unde rinflat ion, wh ic h could eventually cause
t ire fa ilu re . If yo u be lieve th at a t ire may have
been damaged, repla ce the tire as soon as pos­
sible.
- These tires may we ar mo re quickly tha n others.
- Please also remember that, while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in winter/cold season
conditions
All t ires are des igned for certai n pu rposes. The
l ow aspect ratio, ultra h igh performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all-season or winter tires, which offer better
t ract ion under those conditions . We suggest you
u se the recommended s now or a ll-season tires
spe cified for your veh icle, o r the ir equiva lent.
