(D Note
If you leave the child restraint with the
tether strap firm ly installed for several
days, this could leave a mark on the up
ho lstery on the seat cushion and backrest
i n the area where the tether strap was in
stalled . The upholstery would also be per
manently st retched a round the tether
strap. This applies especia lly to leather
seats .
· Using tether straps on rearward-facing
child restraints
C urrently, few rear-facing chi ld restraint sys
tems come with a tether . Please read and
heed the child restrain t system manufactur
er's instructions carefully to determine how to
properly install the tether .
A WARNING -
A child in a rearward-facing ch ild safety
seat installed on the front passenger seat
will be serio usly inju red and can be killed if
the front airbag infla tes - even wi th an Ad
vanced Airbag System.
- The infla ting airbag will h it the c hild
safety seat or infant carrier wi th great
force and will smash the child safety seat
a nd child against the backrest, or door .
- A t ight tether or o ther strap on a rea r
ward-facing child restraint attached to the front passenger seat can p ut too
much pressure on the weight-mat in the
seat and register a heavier weight in the
Advanced Airbag System . The heavier
weight registered can make the sys tem
work as though an adult we re on the seat
and deploy the Advanced Airbag when it

even fata l injury to the ch ild .

than is being generated and ensures an optimal state of charge for the battery.
@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrica l energy is re
quired, but only a litt le is generated. It is also
cr itical if the engine is not run ning and electri
cal components are turned on. In th is in
stance energy is being consumed but non e is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat
in g the distribution of energy .
Vehicle stands for an extended period
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 mai n
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust
ment, may not be available . The convenience
f u nctions w ill be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis
charged .
Intellig ent technolog y 157
If starting capability is jeo pardi zed d ue to en
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired is gene r
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go
out. •

(D Note
To avoid scratching the display, you should never clean it dry.
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 su rfaces and can dam
age them ove r time.
A WARNING
Always read and heed a ll WARNINGS and
t he information<=>
page 164.
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door
trim panels, etc.) should be cleaned at regular
interva ls with a vacuum cleaner. T his 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.
Norm al 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, s ince other fabric surfaces
could be harmed by b rushes .
Normal surface sta ins 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 gently . Do not satu
rate the fabric. Then pat the foam d ry using
absorbent, dry cloths (e.g. microfibe r clo th)
and vacuum it afte r it has dr ied comp lete ly.
Cl eaning stains
Stains caused by beve rages (e .g. coffee, fruit
juice, etc.) can be t reated with a mild deter
gent solution. App ly the dete rgent so lution
wi th a sponge. In the case of s tubbor n stains,
a detergent paste can be applied directly to
Cleaning and protec tion 17 1
the stain and worked into the fabric. After
wards, use copious amounts of clean water to remove the rema in ing detergent. 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 (e.g . ox-gall soap) rubbed in
to them. Afterwards, remove the soap with
water (damp sponge).
A lcohol can be used to treat stains from
grease, o il, lipstick or a ballpoint pen. Melted
grease or dye must be patted off using ab
sorbent mater ial. It may be necessary to re
treat the areas with detergent paste and wa
te r.
In the case of genera l soiling of the uphols
tery and cover material, we recommend hir ing
a specia list that has the equipment to clean
t h e seat covers and othe r fabr ic surfaces by
shampooing and spray extraction .
A WARNING
Always read and heed all WARNINGS and
the info rmation

@ Tips
Open Velcro fasteners on your clothing can
damage the seat cover. Please make sure
that Ve lcro fasteners are closed.
Plastic parts and instrument panel
A lways use a clean clo th moistened in clea r
water to clean these areas . For pe rsistent d irt
u se an Aud i approved
solvent-free p lastic

Natural leather
Applies to vehicles: with natural leather
Audi makes great efforts to maintain the
properties , natural look and feel of interior
leather.
G ener al
We offe r many different types of leather on
our vehicles. Most are different types of nappa
l eather, which has a smooth su rface and
comes in var ious co lo rs .
The in tensi ty of the color de termines the v is u
a l characterist ics and appearance . If the sur
face of the leathe r has a typical natural look,
then the leather is a nappa leather that has
been left in a relatively natural cond ition. This
leather offers par ticularly good com fort and
breathes well . F ine veins, closed grains , in sect
b ites, ski n folds , and subtle var iations in color
remain visib le. These characte ristics demon
strate that the mater ia l is na tural.
Natural nappa leather is not covered by a col
or finish .
It is therefore more sens itive to soil
ing a nd wear, which is something you need to
consider if ch ild ren, an ima ls o r othe r factors
migh t prove to be particularly hard on the
l eathe r.
B y contrast, leather types that are cove red by
a co lored f inish laye r are more durable. This has a positive effect on the leather's resis
t
ance to wear and soiling in dai ly use. On the
other hand, the typ ica l character istics of natu
ral leather are barely or not apparent. Howev
er, th is does not mean that the leather itse lf
is of inferior quality .
Care and handling
Because of the exclusive nature of the types of
l eather that Aud i uses and their unique prop
erties (such as sensit ivity to oils, grease, soil
ing, etc.) , you will need to be somewhat care
ful with these leathers, and a certain type of ca re is req uired. Fo r example, dark clothing
mater ials can disco lor leather seats (especia l
l y if such clo thing is damp and was not dyed
correct ly) . D ust and dirt pa rticl es i n pores,
f olds, and seams can have an abrasive effect
and can damage the leather surface as we ll as
weaken seams.
T he lea ther should be clea ned regularly as
neede d. After hav ing been used for a relat ive ly
long time, your leather seats will acq uire a
rich aged finish . This is a characteristic of nat
u ral leather and a sign of true quality .
In order to maintain the val ue of this nat ural
product
over the life of your ve hicle, you
sho uld follow t he recommendations be low:
(D Note
- T o keep your lea ther from b leaching o ut,
do not allow it to be exposed to bright
sunlight for long periods of time . If yo u
have to leave the veh icle parked outside
for long per iods, cover the leather to
protect it from direct exposure to sun
light .
- Sharp objects on cloth ing, such as zip
pers, rivets o r sharp pieces on belts can
leave permanent sc ratches or scrape
ma rks on the su rface of the leath er.
(l) Tips
- After each time you clean the leather and
a t regular intervals , use a leathe r preser
vative c reme that con tains UV-b locke rs
and tha t wo rks into the leathe r. T his

-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 .
