grease or dye must be patted off using ab ­
sorbent materia l. It may be necessary to re­
treat the areas with detergent paste and wa­
te r.
I n the case of general soi ling of the uphols ­
tery and cover material, we recommend hiring
a specialist that has the equ ipment to clean
the seat cove rs and other fabric surfaces by
shampooing and spray ex traction.

water to clean these areas. For pers istent dirt

some plastics and make it harder for the
airbag to dep loy.
- Never clean the instr ument pane l or the
surface of airbag modules with cleaning
products that contain solvents .

the surface of th is part porous.

Natural leather
Applies to vehicles: wit h natural leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather .
General
We offer many d ifferent types of leather on
our vehicles. Most are d ifferent types of nappa
leather, which has a smooth surface and
comes in various colors .
The intensity of the co lo r determines the visu­
al characterist ics and appearance . If the sur­
face of the leather has a typ ica l natural look,
then the leather is a nappa leather that has
been left in a relat ive ly natura l condit ion. This
leather offe rs particularly good comfort and
breathes we ll. Fine veins, closed grai ns, insect
bites, skin fo lds, and s ubt le va ria tions in color
remain visible . These characteristics demon­
strate that the material is natura l.
Natura l na ppa le ather is not covered by a co l­
o r finish. It is therefore mo re sensit ive to soil­
ing and wea r, which is something you need to
consider if children, animals or other factors
might prove to be part icu larly hard on the
leather.
By contrast, leather types that are covered by
a colo red finish layer are more durable . This
has a positive effect on the leather's resist­
ance to wear and soiling in dai ly use. On the
other hand, the typical characteristics of natu­
ral leather are barely or not apparent . Howev ­
er, th is does not mean that the leathe r itself
is of infe rior quality .
Care and handling
Because of the exclusive nature of the types of
leather that Aud i uses and their unique prop­
erties (such as sens it ivity to oils, grease, soil ­
i ng, etc.), you will need to be somewhat ca re­
ful with these leathers, and a ce rtain type of
ca re is req uired. For example, dark clo thing
ma ter ials can disco lor le athe r seats (especia l­
ly if such clothing is damp and was not dyed
correct ly). Dust and dirt particles in pores ,
folds, and seams can have an abrasive effect ..,..

230 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons¢
& in Re­
pair, core and disposal of the airbags on
page 159.
Disconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capabil ity over a longer period
¢ page 192.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatu res drop . This
is because more power is also consumed while
start ing , and the headlights, rea r window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 232. A well
charged batte ry w ill not only prevent sta rting
prob lems when the weather is cold, but wi ll
a lso last longer.
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from be ing damaged and having
to be replaced .

ment under the floor. Before you check any­
