Changing brake fluid
Have the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh , corros ion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
dec rease braking performance.
Therefore, the brake flu id must be changed
ev ery two year s. Always use new b rake fluid
which conforms to Fede ral Motor Vehicle
Standard "FMVSS
116 DO T 4".
The brake flu id reservoir can be difficult to
r each, therefo re , we recommend that you
have the brake fl uid changed by yo ur author
ized
Audi d ealer. Your dea ler has the correct
too ls, the right brake fluid and the know -how
to do this for you .
A WARNING
-Brake fluid is poisonous . It must be stor
ed only in the closed orig inal container
out of the reach of children!
- Brake fa ilure can result from old or inap
propriate brake fluid. Observe these pre
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l Motor Vehicle Standard
116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid . The correct type of
brake f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cause a vapo r lock if
the b rake fluid is left in the system too

Battery
General information
U nder normal ope rat ing cond itions , the bat
tery in yo ur Audi does not need any ma inte
nance. With
high o utside tempe ra tu res or
l ong daily drives we recommend that you have
the e lectrolyte level checked by a service fa
cility. The electrolyte leve l should a lso be
checked each t ime the battery is charged
<=> page 243.
Have th e battery checked when yo u take your
veh icle in for service. You are well advised to
replace a battery that is o lder than S years .
With certain types of airbag deployment, the battery is disconnected from the veh icle elec
trical system for safety reasons<=>.&

used today are underinflated j ust by looking
at them.
Therefo re, be sure to check tire pressures at
l eas t once a mon th and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See¢
page 254 , Tires and vehicle
load limits
for more important information .
A lways use an accurate tire pressure gauge
when check ing and adjusting inflation pres
sures . Check all of the tires and be sure not to
forget the spare t ire . If the pressure in any tire
i s too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge and keep checking the pressure until
you reach the p ress ure th at is cor re ct for the
l oad (passengers and luggage) and kind of
d riving you plan to do .
I f the p ressu re in any tire is too low , note the
d ifference between the pressure in the cold
tire and the pressure yo u need and add the ai r
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your veh icle and in this manual and the kind
of dr iving you p lan to do.
Never e xceed the m aximum inflation pre s
su re li sted on th e tir e sidewall for any rea
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the co rrect
tire p ressure for the tires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requ ired ti re p ressu re from the tire
pressure label. The ti re pressu re labe l is lo
cated on the drive r's side 8-p illar.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressu re gauge on the valve.
- T he tire pressures should only be checked
and adjusted when the tires a re cold . The
Tire s an d wheel s 253
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
car rying.
- Reins tall the valve stem cap on the va lve.
When should I check the tire pr essure?
The correct tire pressure is especially impor
tant at h igh speeds . T he p ressure should
therefore be chec ked at least once a month
and always before sta rting a jo urney. Do not
f orge t to chec k the ti re p ressu re fo r the spare
whee l¢
page 268.
When should I adjust the tire pressures ?
Adjust the tire pressure to the load you are
carrying. After chang ing a whee l
or replacing
whee ls yo u have to adj ust the ti re press ures
on all whee ls. In addition, yo u m ust then
store the new tire pressures in the tire pres
s u re monitoring system*¢
page 264.
A WARNING
-
Incorrect tire pressures and/or underinfla
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
[IE appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability .
- Inco rrect tire pressures and/or underin
flation can a lso lead to sudden t ire fail
ure, including a blowout a nd sudden de

260 Tires and wheels
-If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires - only use
the spare tire for a short period of time and drive with extra care. Refit the nor
mal road wheel as soon as safely possi
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un
derinflated.
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air
flow to the brakes can them to overheat,
increasing stopping distances and caus
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them
at the factory. The vehicle must have a
chassis designed for run flat tires. Incor
rect use of run flat tires can lead to vehi
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit
ted.
- For technical reasons, it is not generally
possible to use the wheel rims from oth
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve- hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace
the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap.
The valves could get damaged.
@ For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
~ fig. 200.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder
al Safety Requirements in addition to these
grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
Fo r example, a tire graded 150 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how
ever, and may depart significantly from the
norm due to variations in driving habits, serv
ice practices and differences in road character
istics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as ..,.

than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal injury to you and your passen
gers .
A WARNING
Driv ing faster than the maximum speed
for which the w inter t ires on your vehicle
we re designed can cause tire fai lu re in
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per
sonal injuries. Have worn or damaged tires
rep laced immediate ly .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac
celeration of the winter tires and all-whee l
drive tempt you into taking extra r isks. A l
ways remember :
- When brak ing, an all-w heel drive vehicle
hand les in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice condit ions .
@ For the sake of the environment
Use summer tires when weather cond i
tions permit . They are quieter, do not wea r
as quickly and reduce f ue l consumption .
Snow chains
-
Snow chains may be fitted on ly to the front
wheels, and only to certa in tire sizes. Ask yo ur
author ized Audi dealer on wh ic h tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must i nstall them on the front whee ls at
l east.
T he snow chains mus t have low-p rofile links
and must not be th icker than 0 .4 inch
(10,5 mm) , includ ing the lock .
Remove whee l cen ter covers and t rim discs
before pu tting snow c hains on your veh icle
¢ (D . For safety reasons cover caps m ust then
be fitted over the wheel bo lts. These are avail
able from autho rized Aud i dealers .
A WARNING
Using the wrong snow chains for your veh i
cle or installing them incorrect ly can in
crease the risk of loss of contro l leading to
se rious pe rsonal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in
structions p rov ided by t he snow chain
manufacturer.
- W hen driving with s now cha ins never
driv e faster than t he speed permitted for
your specifi c snow chains.
- Always observe local regulations.
(D Note
-Remove snow chains before dr iv ing on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down un necessa rily.
- Snow chains, which come i nto direct con
t act with the whee l rim, can scratch or
damage it. Therefo re, make sure that the
snow chains are s uitably covered. Check
t he pos ition o f th e snow cha ins afte r
dr iv ing a few yards and correct if ne ces
sary. Follow the inst ructions from the
snow chain ma nufactu rer when do ing so .
- If the Adaptive Air Suspens ion * sho uld
ma lf u nction, do not mount or use snow
chains because the vehicle wi ll be ex
treme ly low. If you do drive with snow
chains on while the vehicle is at this lev
el, t he snow cha ins might seve rely dam
