158 Airb ag sys te m
There are some impor tant things you have to
know to make sure that the effectiveness of
the system will not be impa ired and t hat dis­
carded components do not cause injury or pol ­
l ute t he e nvironm ent.
A WARNING
Improp er care, s ervicing a nd r epair proce­
dures can increase t he risk of personal in­
jury and death by preventing an airbag
from deploy ing when needed o r deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel ho rn pad or airbag cover
or the instrument pane l or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units .
- F or cleaning the horn pad or instrumen t
pane l, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners co uld damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect proper ly.
- Never repa ir, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment pane l, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified tech nician who has the t raining
and special equipment necessary.
- For any wor k on the ai rbag system, we
st rongly recommend that you see you r
au thori zed Audi dealer or qualified wo rk­
shop .
- Never mod ify the front bumper or parts
of the veh icle body.
- Always make su re that the side airbag
can infla te wi tho ut interferen ce:
- Never insta ll seat covers or replace­
ment upho lstery over the front seat­
backs that have not been spec ifically
approved by Audi . -
Never use additional seat c ushions that
cover the areas where the side a irbags
inflate.
- Damage to the orig inal seat covers or
to the seam in the area of the side a ir­
bag module must a lways be repaired
immediately by an author ized Audi
dealer .
- The airbag system can be activated only
once. After an airbag has inflated, it
m ust be replaced by an autho rized Aud i
dea le r o r qualified technician who has
the techni cal info rmation, training and
specia l equipment necessary.
- T he airbag system can be deployed only
once . After an airbag has been deployed,
it mus t be replaced with new replace­
ment parts designed an d approved espe­
cially fo r your A udi model version. Re­
p lacement of complete airbag systems
or airbag components must be per­
formed by qualified workshops on ly.
Make sure that any airbag serv ice action
is entered in your Audi Warranty

With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use other MMI func­
tions, the battery is being discharged .
If starting capability is jeopardized due to en­
ergy consumption, the following warning ap­
pears in the MMI display :
Please start the engine soon or the system
will be turned off.
The warning indicates that the system will be
turned off automatically after 3 minutes . If
you wish to continue using the functions , you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is being driven , the battery can be ­
come discharged . This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­ brium, consumers which require especially
large amounts of energy are temporarily cut
back or switched off . Heating systems in par­
ticular require a great deal of energy. If you
notice , for example , that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or switched
off. These systems will be available again as
soon as the energy balance has been restored.
You will also notice that engine idle speed has
been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener­
ated and the battery is charged.

Care of interior
Infotainment components
The Radio/MM!* display may be clea ned with
a soft cloth and commercially-availab le "LCD
cleaner" . The cloth should be coated lightly
when the cleaning solution when cleaning the
display .
The
MMI* controls must be cleaned first with
a brush so that dirt does not enter the un it or
enter between the buttons and the housing.
Then wiping the controls with a cloth damp ­
ened with dish detergent and water is recom ­
mended.
(D Note
- To avoid scratch ing the display, you
shou ld never clean it dry.
- To prevent damage, make s ure fl uids do
not enter the controls.
Aluminum trim
Use only neutral-pH products to remove spots
and depos its from alum inum surfaces.
Chrome care products and alkaline cleaners
will attack alum inum surfaces and can dam­
age them ove r time.
A WARNING
Always read and heed all WARNINGS and
other information
r::> page 199.
Fabrics and fabric coverings
Fa brics and fabric coverings (e.g. seats, door
trim panels, etc.) should be cleaned at regular
intervals with a vacuum cleaner. This removes
surface dirt particles which could become em­ bedded in the fabr ic through use. Steam
cleaners should not be used, because the
steam tends to push the dirt deeper into the
fabric and lock it there.
Cleaning and protection 205
Normal cleaning
Generally, we recommend using a soft sponge
or a lint -free microfiber cloth to the clean fab­
ric. Brushes shou ld only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Normal sur face stains can be cleaned using a
commercially available foam cleaner . Spread
the foam on the s urface of the fabric with a
soft sponge and work it in gently. Do not satu­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g. m icrofiber cloth)
and vacuum it after it has dried completely.
Cleaning stains
Stains caused by beverages (e.g. coffee, fr uit
jui ce, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubborn stains,
a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copious amounts of clean water to
remove the remaining deterge nt. Apply the
water with a damp cloth or sponge and pat
the fabric dry with an absorbent, dry cloth.
Stains from choco late or makeup should have
detergent paste rubbed into them. After­
wards, remove the soap with water (damp
sponge).
Alcohol can be used to treat stains from
grease, oil , lipstick or a ballpoint pen. Melted
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
ter.
In the case of genera l soiling of the upho ls­
tery and cover material, we recommend hiring
a specia list t hat has the equipment to clean
the seat covers and other fabr ic surfaces by
shampooing and spray extraction.
