Weatherstrips
To seal properly, the weatherstrips around the
front lid, doors, eng ine compartment lid, etc .
must remain pliable . Spray the weatherstrips
with silicone or coat them with talcum pow­
de r or glyce rine to retain the flexibility of t he
r u bber and to protect them against free zing
in the winte r.
A WARNING
Always read and heed a ll WARNINGS and
the information
¢page 161.
@ Tips
Keep silicone sprays off the windsh ield to
avoid wiper smear in rain.
Wheels
Regular care is required to preserve the deco­
rative appearance of the wheels . Road sa lt
and brake dust must be washed off regularly
or the wheels w ill be damaged .
Use only special acid-free cleaning agents. Yo u

184 Checking and filling
Brake fluid
Notice
Have the brake fluid changed by an experi­
enc ed technician .
Brake fluid abso rbs moisture from t he a ir. If
the water content in the brake fluid is t oo
high, corrosion 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 b rak ing performance.
Therefore, the brake flu id must be changed
e ver y two y ear s. Always use new brake fluid
which confo rms to Fede ral Motor Vehicle
Standa rd "FMVSS 1 16 DO T 4".
Brake fluid is rep laced according to the Audi
maintena nce service schedule . Your author­
ized Audi dealer is equipped with the necessa­
ry special tools and rep lacement parts , has
the necessary expe rtise, and c an d ispose of
the used fluid .
& WARNING
-Brake fluid is po isonous. It must be sto r­
ed on ly in the closed orig inal container
o ut o f the reach of children!
- Brake fa ilure can result from old or inap ­
propriate b rake fluid . Observe these pre­
caut ions:
- Use only bra ke fluid that meets SAE
specifi cation
J 1 703 and co nfo rms to
F ederal Motor Vehicle St andard 116 .
A lways check with you r a uthorized Aud i
dea ler to make s ure you are using the
correct brake fl uid. T he correct type of
brake fluid is a lso indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fl uid is left in the system too
long . This can ser ious ly affect the effi­
cie ncy of the bra kes as well as yo ur
safety. This could result in an acc ident .
(D Note
Brake fluid will damage the paint of you r
vehicle .
@ For the sake of the environment
Because o f the prob lem of p rope r disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
recommend that yo u have the brake fl uid
changed by yo ur authorized Aud i dea le r.
Battery
General information
All work on the battery requires technical
knowledge.
The battery is located behind the cover i n the
l uggage compa rtme nt. Remove the cover by
pushing it to the left and lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main­
tenance se rv ices .
You are we ll advised to replace a battery that
is older than S years .
Disconnecting the battery terminal s
Some vehicle functions (power window reg u­
lators, for example) are lost if the battery te r­
mina ls are disconnected . T hese functions have
to be relearned after the battery termina ls are
connected again . To prevent th is, the battery
shou ld only be disco nnected from the ve hicle
electrica l system when abso lutely necessary
f o r repai rs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies­
cent current consume rs even when the vehicle
i s not used . With extended pe riods of non-use
i n the
cold season, you should have the ve hi­
cl e battery removed by an autho rized Aud i
de aler or qu alified workshop and stored in an
frost -free place. This preven ts the battery
from "freezing" and thereby being dest royed.
D uring the
warmer seasons it is eno ugh to liJ>

190 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­

Because tec hnical changes may be made to
vehicle equ ipment dur ing the model yea r, a l­
ways compare the tire size designation on the
tire pressure labe l on you r vehi cle w it h the
tires on your vehicle. Make s ure that the ti re
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle . These load lim its are technically refer­
red to as the vehicle's G ross Vehicle We ight
Rati ng ("GVWR"). The G ross Ax le Weight Rat­
i ng ("GAWR") is the max imum load that can
be app lied at each o f the veh icle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stic ker labe l located either
on the driver's side B-pillar. The tire pressure
labe l on your Audi lists the maximum com­
b ined weight of all of the occupants and lug­
gage or other cargo that the veh icle can carry.

.&_ WARNING
Overloading a vehicle can cause loss of ve­
h icle cont ro l, a crash o r other accident, se ­
r ious pe rsonal injury, and even death.
- Ca rrying more we igh t than your veh icle
was designed to carry wi ll prevent the
vehicle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been over load­
ed can fail s uddenly ca us ing loss of con­
trol and a crash.
.&_ WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
f lation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of veh icle cont ro l.

The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Your Audi has 2 seat ing
positions in the front for total seat ing capac i­
t y of 2. Each seating posi tion has a safety belt
c::> page 109, Safety belts.
The fact that there is an upper limit to your
ve hicle's Gross Veh icle Weight Rating means
that the total weight of whatever is being car­
ried in the veh icle is limited . The more passen­
gers in the veh icle or passengers who a re
heavier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The t ire pressure label on your Audi also lists
the maximum combined we ight of all of the
occupants and luggage o r othe r cargo that
the vehicle can carry. For the location of the
la be l
c::>page 193, fig. 150.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, includ ing a b lowout
and sudden deflation, causing loss of
control and a crash.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
Tires and wheels 197
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX
KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
¢ page 193,
fig. 150.
2. Determine the combined weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 193, fig. 150.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci-
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
c le, the amount of available .,..
