ment on page 165.
.. Read the brake flu id level from the brake
fluid reservoir
9 page 167, fig. 130 . The
brake f lu id leve l must be between the "MIN"
and "MAX" markings.
The brake f luid reservoir is located behind the
rear partition of the engine compartment on
the left side
9 page 167.
The fl uid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
If the brake fluid level falls considerably be­
l ow the "M IN" mark, the brake wa rning/indi ­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on ¢
page 14 . Do not
continue to operate the vehicle. The complete
brake system shou ld be thoroughly checked
by an authorized Audi dealer or other quali­
f ied fac ility and the cause corrected . If the
b rake fluid level is too low, the brake warn ing/
i ndicator light w ill illuminate . Co ntact an au­
thor ized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid abso rbs moistu re from the a ir . If
the water content in the brake fluid is too
hi gh, cor ros ion in the b rake system may result
after a per iod of t ime . The bo iling po int of t he
b ra ke fluid w ill also decrease considerab ly and
decrease braking performance.
Therefore, the brake flu id must be changed
e very two year s. Always use new b rake fluid
which confo rms to Fede ral Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id rese rvoi r ca n be difficult to
r each, therefo re , we recommend that yo u
h ave the brake fl uid changed by you r autho r­
i zed
Audi dealer . Your deale r has the correct
Checkin g and fillin g 175
tools, the right brake fl uid and t he know -how
to do this for you .
A WARNING
-Brake flu id is poisonous. It must be stor­
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can res ult from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only b rake fluid th at mee ts SA E
spe cificat ion
J 17 03 and conforms to
Federa l Mo to r Ve hicl e Standard 1 16.
Always check with yo ur authorized Au di
dealer to make sure yo u are using the
correct brake fluid. The cor rect type of
brake f luid is also ind icated on the
brake f luid reservoir .
- The bra ke fluid must be new. Heavy use
of the brakes ca n cause a vapor lock if
the brake fluid is left i n the system too
long. This can se riously affect the effi­
c iency of the b rakes as well as your
safety , T his could result in an accide nt.
(!) Note
Brake fluid will damage the pai nt of your
vehicle.
@) For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the nec essary expertise, we
r ecommend that yo u have th e brake flu id
c hanged by you r aut ho rized Aud i dea le r.

188 Tire s and wheel s
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
ga uge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exc eed th e maximum inflati on pres­
sure listed on th e tir e s idewall for any rea ­
s on.
Remembe r that the vehicle manufacturer, not
the t ire manufactu rer, determ ines the correct
tire pressure for the t ires on your vehicle.
It is important to check the tire pressure when
the t ires a re cold .
- Read the requ ired tire press ure from the tire
pressure label located on driver's side B-pil­
lar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures sho uld only be checked
and adjusted when the tires are cold. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the valve stem cap on the valve.
Wh en should I check the tir e pr essure?
The correct tire pressure is espe cially impor ­
tant at high speeds . The pressure should
therefore be checked at least once a month
and a lways before starting a journey.
When should I ad ju st the tire pressures?
Adj ust the t ire p ressu re to the load yo u are
carry ing . After changing a wheel
or replacing whee
ls you have to adjust the tire p ressures
o n all whee ls. In addition, yo u m ust then initi­
alize the new tire press ures in the t ire pres­
s u re monitoring system¢
page 199.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious pe rsonal injury
or even death.
- When the warn ing symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
s topping ability.
- I nco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and su dden de­
flation, ca using loss of veh icle cont ro l.
- The drive r is responsible for the co rrec t
tire pressures for all tires on the veh icle .
The applicable pressure values are loca t­
ed on a sticker on the driver's side B -pil­
lar.
- On ly when all tires on the vehicle are fil­
led to the correct pressu re, the tire pres­
sure mon itor ing system can work cor­
rectly.
- The use of incorrect tire pressu re va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system.
- Always inf late tires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with unde rinf lated tires bend
mo re, letting them get too hot resulting
in tre ad separation, sudden tire failure
and loss of cont ro l.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- 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
deri nflated.
- 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 and a
factory-installed tire pressure monitor­ ing system that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle 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
permitted .
Tires and wheels 195
@ Note
-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
¢ page 192,
fig. 142 .
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.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •

Speed rating (letter code)
for a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code
( c> page 184) is
on the side wall of the tire
c::> page 192 .
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an acc ident and serious
personal injury to you and yo ur passen­
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immed iately.
- 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
wh ich 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 winte r tires and all-whee l
drive tempt you into taking extra r is k s . A l­
ways remember:
- When brak ing, an a ll-wheel 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 conditions.

@) For the sake of the env ironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be fitted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used .
If you are go ing to use snow chains, then you
must install them on the front wheels at
least .
The snow chains mus t have low-prof ile links
and must not be th icker than 0 .53 inch
(13.5 mm), includ ing the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (D . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail ­
able from authorized Aud i dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or insta lling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions provided by the snow chain manufacturer .
- When driving with snow chains never drive faster than the speed permitted for
your specific 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 unnecessarily.
- Snow chains, which come into direc t con­
tact with the whee l rim, can scratch or
damage it . Therefore, make sure that the .,.
