in the area where the tether strap was in­
stalled. The upholstery wo uld a lso be per­
manently stretched around the tether
strap. This applies especially to leather
seats.
Using tether straps on rearward-facing
child restraints
Curren tly , few rear-facing child res traint sys ­
tems come with a tethe r. P lease re ad an d
heed the child res traint system manufactur­
er's instructions carefully to determine how to
properly insta ll the tethe r.
A WARNING
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates -even with an Ad ­
vanced Airbag System.
- The inflating a irbag w ill hit the child
safety seat or infant carrier w ith g reat
force and w ill smash the ch ild safety seat
and child against the backrest, ce nte r
armrest, or door.
- A tight tether or other st rap on a rear­
wa rd-fa cing child restra int attached to
the fro nt p assenger se at can put too
much pressure on the weight -ma t in the
seat and register a heavier we ight in the
Advanced Airbag System. The heavier
we ight registered can make the system
work as though an ad ult were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing se rious or
ev en fatal injury to the child.
- If you must install a rearward facing child safety seat o n the front passenger
seat because of exceptional circumstan­ ces a nd the

190 Intelligent technology
Intelligent technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facture rs for the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for example, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a ve ry limited pe riod of
time and stored when a system fault or other
cond ition is sensed by a control unit. Some of
the data then stored may re late to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic stabilization
program (ESP)
Description
ESP helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the engine is running. ESP detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw) out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steer ing assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
liJ in the instrument cluster
blinks when ESP is taking action to help you
control the vehicle.
ESP has limitations.
It is important to remem­
ber that ESP cannot overcome the laws of
physics. It will not always be able to help out
under all conditions you may come up against.
For example, ESP may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered w ith water,
slush or snow, ESP cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESP will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESP cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESP is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic; and weather condit ions. ESP can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a ve hicle
on the road if road departure is a result of
driver inattention. Instead, ESP improves the
poss ibility of keeping the vehicle unde r con­
trol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESP can
provide any assistance, you may not experi­
ence the benefits of ESP .

Normal cleaning
Generally, we recommend using a soft sponge
or a lint -free microfiber cloth to the clean fab­
ric . Brushes should only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Normal surface stains can be cleaned using a
commercially available foam cleaner. Spread
the foam on the surface of the fabric with a
soft sponge and work it in gent ly. Do not sat u­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g . microfiber cloth)
and vacuum it after it has dr ied completely.
Cleaning st ain s
Stains caused by beverages (e.g. coffee, fruit
juice, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubbor n stains,
a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copio us amounts of clea n water to
remove t he remain ing detergent. Apply the
water with a damp cloth or 5ponge and pat
the fabric d ry with an absorbent, dry cloth.
Stains from chocolate o r make up s hou ld have
dete rgent paste (e.g . ox-gall soap) r ubbed in­
to them. Afterwards, remove the soap w ith
water (damp sponge).
A lcohol can be used to t reat stains from
grease, oi l, lipstic k or a ballpo int pen. Me lted
grease or dye must be patted
off using ab ­
sorbent materia l. It may be necessary to re ­
treat the areas with dete rgent paste and wa­
ter.
I n the case of genera l so iling of the uphols­
tery and cover materia l, we recommend hiring
a specialist that has the equ ipment to clean
the seat covers and other fabric surfaces by
shampooing and spray extraction.

@ For the sake of the environment
Because of the problem of proper disposa l
of brake fl uid as we ll as the special tools
requ ired and the necessary expert ise, we
recommend that you have t he brake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ive s we recommend that you have
the electro lyte level checked by a service fa­
cility . The electrolyte level shou ld a lso be
checked each time the battery is charged
¢ page 235.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.
in Re ­
pair, care and disposal of the airbags on
page 159.
Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo­
nen ts are gr adually cut b ack o r swi tched off .
This redu ces energy cons umption and main­
tains starting capab ility over a longer per io d

opera te , such as the Conven ience key*, the re­
mote control or the power seat adjustment .
T he convenience functions will be ava ilab le
again when you switch on the ign ition and
start the eng ine.
Winter operat ion
D uring the w inte r mon ths, bat tery capacity
tends to dec rease as temperatures drop . This
is beca use more power is a lso consumed wh ile
starting, and the headlights, rear window de­
fogger, etc., are used more often.
Avoid unnecessary powe r consum ptio n, pa r­
ticu lar ly in city traffic or when traveling only
short distances. Let your autho riz ed Audi
dealer check the capacity of the vehicle bat­
te ry before w inter sets in¢
page 235 . A well
c h arged battery will not on ly prevent s tarti ng
problems w hen the weather is cold, but wi ll
also last longer.
(D Tips
If you r vehicle is left s tandi ng for seve ral
weeks at extremely low temperatures, the
vehicle ba ttery s hould be removed an d
s to red w here i t w ill not fr eeze . T his w ill
p revent it from be in g damaged and having
to be replaced.
Working on the battery
Be especially careful when working on or near
the bat tery.
