(D Note
- Your vehicle is equipped with a specia l
battery. Installing a different type of
battery can cause prob lems in the vehi
cle electrical system. When replacing the
vehicle battery, always install one with
the same spec ificat ions as the original
battery .
- Make sure that the gas venting hose is
always connected to the o riginal open ing
on the battery side. Otherw ise gasses or
ba tte ry acid could leak out .
- Battery holder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 179, Working on the battery be
fore performing any work on the batte ry.
@) For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you . Batteries contain sulfur ic ac id and
lead and must always be disposed of prop
erly in compliance with a ll environmenta l
reg ulations. D isposing of vehicle batteries
improperly is very dangerous to the envi
ronment. Make sure that the removed bat
tery ca nnot overbalance, otherwise sulfu

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . T ires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tively small patch of rubber on eac h tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han
d le, avoiding damage from road hazards and
r eg ularly inspec ting t ires for damage i nclud
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in
cluding tread separat ion and blowouts.
Avoiding damage If you have to d rive over a curb or similar ob
stacle, drive very slow ly and as close as possi
b le at a right angle to the curb.
A lways keep chemicals includ ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .

Unidirectional tires
A un idirectional tire can be identified by ar
rows on the s idewa ll, that po int in the direc
tion the t ire is designed to rotate. You mus t
f ol low the specified di rection o f rotation . T his
is necessary so that these tires can develop
their optimum characteristics regarding grip, road noise, wear and hydrop laning resistance.

- Th e use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specif ied tire pressure va lues
for the tires and the correct pressures for
the funct ion of the tire pressure mo nitor
ing system .
- Always inflate tires to the recommended
and correct tire pressure befo re drivi ng

and loss of control.
- Excess ive speed and/ove rloading can
cause heat bui ld-up, sudden t ire fa ilu re
and loss of control.
- If the t ire pressur e is too low or too high,
the ti res w ill wea r pre matu rely a nd the
vehicle will not h and le we ll. -
If the tire is not flat and you do not have
to change a wheel immediately, drive at
red uced speed to the nearest service sta
tion to check the t ire pressure and add
air as req uired.
(D Note
Driving without valve stem caps can ca use
damage to the tire valves. To prevent this,
a lways make sure that factory installed
valve stem caps o n all whee ls are sec urely
mounted o n the valve.
@ For the sake of the environment
Underinflated tires w ill also increase the
fuel consum ptio n.
Tires and vehicle load limits
T he re a re lim its to the amount of load o r
weight tha t any veh icle a nd any tire can ca rry .
A vehi cle that is overloaded will no t handle
well and is mo re d iff icu lt to stop . Ove rloading
can not only lead to loss of vehicle control,
but can also damage important parts of the
vehicle and can lead to sudden tire fa ilure, in
clud ing a b lowout and sudden deflation that
can cause the vehicle to cras h.
Your safety and that of your passengers also depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the veh icle . These
load lim its are technically referred to as the
vehicle 's
Gro ss Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all facto ry installed accessor ies, a full
tank of fuel, o il, coolant and other fluids plus
max imum load . T he max imum load includes
t h e nu mbe r of p assenge rs t hat the vehicle is
i n tended to c arry ("seat ing c apac ity") wi th an
ass umed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating position
and the total weight of any luggage in the ve -
hicle. ..,_

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 seating
positions in the front for total seat ing capac i
ty of 2. Each seating posit ion has a safety belt
c::> page 101, 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 187, fig. 148.
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 yo ur 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 191
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 187,
fig. 148.
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 187, fig. 148.
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 .,..

A WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious personal injury !
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning " and loss of
control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo
ry ." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

sidewall) .
A lways check your tire pressure monitoring
system ind icator after replacing one or more
tires on your vehicle. If the tire pressure mon i
toring system ind icator flashes, or is on, your
system is not work ing properly.
A WARNING
- Us ing incorrect or unmatched ti res and/
o r wheels or imp roper tire and whee l
c ombin ations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of or ig inal
f ac to ry-installed t ires or other combina
tions that have been spec ifically ap
proved by the vehicle manufacturer .
- Tires age even if they are not being used
and can fail suddenly, es pecially at high
speeds. Tires that are more than 6 years

f as ter than their rated speed can fail
s u dden ly .
- Overloading t ires cause heat build- up,
s u dden tire failure, incl uding 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 technica l reasons it is not always
possible to use whee ls from other vehi
