220 Check ing and filling
- To r educe the danger of explosion, never
co nnect or disconn ect cha rger cables
wh ile the c harger is operating.
- Fast char ging a battery is dangerous and
shou ld on ly be attempted by a compe
tent technician w ith the proper equip
ment .
- Battery acid that may spill d uring charg
ing should be washed
off with a solution
of warm water and baking soda to neu
tralize the acid.
(Q) Note
Never use a fast charger as a booster to
start the engine . This will seriously dam
age sensitive electronic components, such
as control units, relays, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip
ment battery.
In tell igent energy management in your veh i
cle is respons ible for d istributing the e lectr i
cal energy throughout you r vehicle

charged better then vehicles w ithout this sys
tem . To make sure the additional e lectrica l en
ergy is available once again after you have
changed the battery, we recommend that you install batteries o f the same type and ma nu
facture only (the same as those installed at
the time your vehicle was delivered). Specifi
cations are listed on the battery hous ing. You r
author ized Audi dealer must code the battery
in the ene rgy managemen t system to enable
you to use the ene rgy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca
pac ity, voltage ( 12-volts), amperage, con
struction and plug sea ling. When installing the battery, make su

off.
(D Note
Make sure the ventilat ion hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because o f the p rob lem of p roper disposal
of a battery, we recommend your author
i zed Audi dealer change the battery fo r
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop
erly in comp liance with all environmental
regula tions. Dispos ing of veh icle batter ies
i mprope rly is very dange rous to the envi

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 . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your 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 safe ly han
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ
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 I f you have to drive over a curb or similar ob
stacle, drive very s low ly and as close as possi
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on r ims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one s ide, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar
rows on the s id ewa ll, that po int in the direc
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information
¢ page 249.
A WARNING
-New tires or tires that are o ld, worn or
damaged cannot provide maximum con
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail
ure, including a blowou t and sudden de
fl ation, c rashes and seriou s personal in
juries . Have wo rn or damaged t ires re
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.
Page 225 of 286

-Never mount used tires on yo ur vehicle if
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 18 2 T ire press ure label : located on driver's side B·
pillar
Tire pressure genera lly refers to the amount
of air in a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat ion pressu re i n a "cold" tire that counts.
T herefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires
a re a ma jo r cause of s udden tire failure. Keep·
i n g tires at the right pressu re is also impor
tant for safe and responsive vehicle handling,

XL= reinfo rced or extra lo ad tire. It may al so appear a s xl, EX TRA LOAD , or R F on the tire side-
w all.
The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during the model year, a l
ways compare the tire size designation on the
tire pressure label on your vehicle with the
tires on your vehicle. Make sure that the tire
size information on the vehicle label is the
same as the size of the t ires on the vehicle.
This is especially important if the vehicle be
l ongs to someone else or you bought the ve hi- cle w
ith 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 making sure that
l oad lim its are not exceeded. Vehicle load in
cludes everybody and everything in and on the
vehicle. These load limits are technically refer
red to as the veh icle's Gross Vehicle Weight
Rat ing ("GVWR"). The Gross Axle We ight Rat
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two ax les .

forget the spare tire. If the p ress ure in any tire
is 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 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 a ir
that you need to reach the correct pressure for
the veh icle 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 exce ed the ma ximum inflation pres
s ur e listed on t he tire s idewall for any re a
s on.
Remember that the vehicle manufacturer , not
the t ire manufacturer , determ ines the co rrect
tire pressure for the tires on your veh icle .
It is important to check the tire pressure when
the t ires a re cold .
- Read the req uired tire press ure from the tire
pressure label. The tire pressure labe l is lo
cated on the driver's side 8 -p ill ar . The tire
pressure label lists the recommended cold
t ir e inflat io n pressu res for the veh icle at its

- Turn the valve stem cap counter -clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
- The tire pressures should on ly be che cked

When should I check the tire pressure?
T he co rrect tire pressu re is especially impor
tant at h igh speeds. The pressure should
therefore be checked at least once a month
and always before sta rting a jo urney . Do not
forget to check the tire pressure for the spare
whee l.
When should I adjust the tire pres sures?
Adjust the t ire pressure to the load you a re
carrying . After changing a whee l
or replacing
whee ls yo u have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi
alize the new tire pressures i n the t ire pres

A WARNING
Incorrect ti re p ressu res and/or u nderinfla
tion can lead sudden ti re fa ilu re, loss of
control, collision, se rio us pe rsonal inju ry
or even death.
- When the
RI] warning symbol appears i n
the ins trumen t cluster, stop and inspec t
the t ires.
- In co rrec t tire p ressure a nd/or underi nfla
tion can ca use increased tire we ar and
can affect the hand ling of the vehicle and
stopping ability.
- In correc t tire pressures and/or underin
flation can a lso lead to s udden t ire fail
ure, including a blowout and sudden de
flation, ca using loss of vehicle contro l.
- The drive r is responsib le for the co rrect
tire pressures for all tires on the vehicle.
The applicable pressure values are locat
ed on a sticke r on the dr iver's s ide 8-pil
lar.
- On ly when all tires on the vehicle are fil
led to the correct pressure, the t ire pres
sure mon itor ing system* can work cor
rectly .
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the drive r
observe the spec ified t ire p ress ure val ues
for the tires and t he correct pressures fo r .,. •

Incorrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impairing the safety of the vehi
cle. If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see~
page 184 .
.8_ 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 toss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires 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.

- Never mo unt used tires on your veh icle if
you are not sure of the ir "previous histo

aged even thoug h the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

The relative perform a nee of ti res depends
upon the actua l conditions of their use, how
ever, and may depart sign ificantly from the
norm due to var iat ions in dr iving habits, serv
ice practices and differences in road character
istics and climate .
Trac tion
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 measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢,&. .
Temp erature
The temperature grades are A (the h ighest),
B, and
C, representing the t ire's resistance to
the generat ion of heat and its ability to dissi
pate heat when tested under controlled condi
tions on a specified i ndoor laboratory test
wheel.
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa ilu re ¢ ,&. .
The grade
C corresponds to a level of perform
ance which all passenger car tires must meet
u nder the Federa l Moto r Veh icle Safety Stand
a rd No.
1 09. G rades Band A represent h igher
l eve ls of perfo rmance on the laboratory tes t
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this ti re is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering, hydrop lan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es
tablished for a t ire that is p roperly inflated
and not overloaded. Excessive speed, un
derinflation, or excessive loading, either

separately or in combinat ion, can ca use
heat bui ldup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter o r "snow" tires, those
with very deeply cut tread. These tires should
o nly be used in pairs and be installed o n all
four wheels . Make sure you purchase snow
t ires that are the same size and construction
type as the other tires on you r vehicle.
Your vehicle is equipped with all wheel drive,
th is w ill improve traction during winter driv
i ng, even with the standa rd tires . However, we
strong ly recommend that you always equip all
fo ur wheels on you r vehicle wit h corre ct ly fit
ted winter tires or all-season t ires, when win
te r road cond itions are expected . This also im
proves the veh icle's braking per formance and
reduces stopping dista nces.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur wheels .
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire size s. Use
o nly rad ial w inter t ires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm) .
Only drive w ith w inter t ires under w inter con
dit ions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
whee l
¢page 233.
Please a lways remember that winter tires may
have a lowe r speed rating than the tires o rigi -
nally installed on your vehicle at the time it .,.
