Care of interior
Aluminum trim
Use on ly neutral -pH products to remove spots and deposits from
a luminum surfaces. Chrome care products and alka line cleaners
wi ll attack aluminum surfaces and can damage them over t ime.
& WARNING
Alway s read and heed all WARNIN GS and the inform ation
~ page 200 . •
Fabrics and fabric coverings
Fabrics and fabric coverings (e .g. seats, door trim pane ls, etc.)
should be cleaned at regu lar intervals with a vacuum cleaner. This
removes surface dirt particles which could become embedded in
the fabric through use . Steam c leaners should not be used, because
the steam tends to push the dirt deeper into the fabric and lock it
there .
Norm al c leanin g
Generally, we recommend using a so ft sponge or a l int -free
microfiber cloth to the clean fabric. Brushes should only be used for carpets and floor mats, since other fabric surfaces could be harmed
b
y brushes .
Normal surface stains can be cleaned using a commercially avail­
able foam cleaner . Spread the foam on the surface of the fabric with
a soft sponge and work it in gently. Do not saturate the fabric. Then
pat the foam dry using absorbent, dry cloths (e.g. microfiber c loth)
and vacuum it af ter it has dried complete ly .
C leaning st ains
Stains caused by beverages (e.g . coffee, fruit juice, etc.) can be
treated with a mild detergent solution. Apply the detergent so lution
with a sponge . In the case of stubborn stains, a de tergent paste can
be applied directly to the stain and worked into the fabric. After ­
wa rds, use copious amounts of clean wa ter to remove the
remaining detergent . App ly the water with a damp cloth or sponge
and pat the fabric dry w ith an absorbent, dry c lo th.
Stains from choco late or makeup shou ld have detergent paste (e .g.
ox -gall soap) rubbed into them . Afterwards, remove the soap with
water (damp sponge).
Alcoho l can be used to treat stains from grease, oi l, lipstick or a ba ll­
point pen . Melted grease or dye must be patted off using absorbe nt
material. It may be necessary to retreat the areas with detergent
p aste and wa ter.
I n the case of general soiling of the upholstery and cover material,
we recommend hiring a specialist that has the equipment to clean
the seat covers and other fabr ic surfaces by shampooing and spray
extraction.

Natural leather
Aud i m akes gre at effo rts to maint ain th e pr oper ties,
n atur al look and feel of interi or le ather.
Gener al
We offe r many d ifferent types of leathe r on our vehicles. Mo st are
different types of nappa leather , which has a smooth surface and
comes in various co lo rs.
The intensity o f the color determ ines the visua l characteristics and
appearance. If the surface of the leather has a typical natura l look,
then t he leather is a nappa lea ther that has bee n left in a re latively
natura l condition. This leather offers particu lar ly good comfort and
b reathes well. Fi ne veins, closed g ra ins, insect bites, skin folds, an d
subtle variations in co lor remain visib le. These characteristics
dem onstrate that the mater ial is natural.
Natura l nappa leather is not covered by a co lor finish . It is therefore
more sensitive to soil ing and wear, which is something you need to
consider if chi ldren, animals or other fac tors might prove to be
particularly hard on the leather.
By con trast, leather types that are covered by a colo red fin ish layer
are more durable. This has a positive effect on the leather's resis ­
tance to wea r and s oiling i n daily use . On the ot her hand, the typical
characteristics of natura l leather are barely or not apparent .
However, this does not mean that the leather itself is of inferior
qua lity .
Care and handling
Because of the exclusive nature of the types of leather that Audi
u ses and thei r unique p rope rties (suc h as sens it ivity to oi ls, g rease,
soi ling, etc .), you wi ll need to be somewhat careful w ith these
leathers, and a certain type of care is required. For example, dark .,.

Engine compartment
Be es pecially caref ul when cle aning the engine compart­
ment.
Alwa ys swit ch off the ignition before cle aning the engine => & .
Plenum pan el
Remove leaves from the plenum pane l in front of the w indshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
inter ior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion ­
pro tected at the factory.
Good anti -co rros io n treatment is very important, particularly in the
winter. If the vehicle is frequent ly driven on salt treated roads, the
enti re eng ine compartmen t and p lenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage . At the same time, the unde rside o f the vehicle shou ld be
washed as we ll.
I f the engine compartment is cleaned at any time with grease
removing solut ions
ll, or if you have the engine washed, the anti ­
corrosion treatment is almost a lways removed as well. It is therefore
essential to have a long-lasting corrosio n pro tec tion reapp lied to a ll
surfaces, seams, joints and components in the engine compart ­
ment .
& WARNING
Be awa re: Th e engine comp artment of any motor vehicle is a
potentially hazardou s area .

Fuel supply and filling your fuel tank
The label on the inside of the fuel filler flap tells you the correct fuel
for your vehicle. For more information about fuel specifications, see
~ page 214.
Your vehicle fuel tank has an on -board refuelling vapor recovery
system. This feature helps to prevent fuel vapors from escaping
from the tank and polluting the environment while you refuel your
vehicle. In order to fill the tank properly while protecting the envi­
ronmen t, please follow this refueling procedure carefully.
& WARNING
Under normal operating conditions, never carry additional fuel
containers in your car. Gas canisters and other containers used to
transport fuel can be dangerous. Such containers, full or empty,
may leak and could cause a fire in a collision. If you must transport
fuel to use for your lawn mower, snow blower, etc ., be very careful
and always observe local and state laws regarding the use, trans­
portation and storage of such fuel containers . Make certain the
container meets industry standards (ANSI/ASTM F852 -861.
0 Note
Never drive your vehicle until the fuel tank is completely dry. The
irregular supply of fuel can cause misfiring . Gasoline could enter
into the exhaust system and damage the catalytic converter. •

•
- Select a medium refuelling rate so that the nozzle
switches off automatically when the tank is full.
Putting the fuel cap back on
- After filling your tank, twist the fuel filler cap clockwise
until you hear a definite click.
- Close the fuel filler flap.
To avoid fuel spilling or evaporating from the fuel tank always close
fuel filler cap properly and completely. An improperly closed fuel
filler cap may also cause a message in the driver information system =>
page 24 or cause the MIL lamp=> page 26 to come on.
& WARNING
Improper refueling or handling of fuel can cause fire, explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries.
• Failure to shut the engine off while refueling and/or to insert
the pump nozzle fully into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire.
• Never use a cellular telephone while refueling . The electromag­
netic radiation can cause sparks that can ignite fuel vapors and
cause a fire .
• Never get back into your vehicle while refueling. If in excep­
tional circumstances you must get back in your vehicle while refu­
eling, make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
& WARNING (continued)
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container, full or empty may leak and could cause a fire, especially in a crash .
• If, under exceptional circumstances, you must transport a
portable fuel container, please observe the following: -Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors causing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling.
- If filling a portable container made of metal, the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment.
Fuel vapors are highly flammable.
- Always observe local and state/provincial laws regarding the
use, storage and transportation of fuel containers
- Make certain the fuel container meets industry standards
(ANSI / ASTM F852-86l.
(D Note
If any fuel has spilled onto the car, it should be removed immedi ­
ately to prevent damage to the paint.
<£> For the sake of the environment
As soon as the correctly operated nozzle switches off automatically
for the first time, the tank is full. Do not try to add more fuel because
fuel may spill out. In addition, the expansion space in the fuel tank ..,_
