soiling, etc.I, you will need to be somewhat careful with these
leathers, and a certain type of care is required. For example, dark
clothing materials can discolor leather seats (especially if such
clothing is damp and was not dyed correctly). Dust and dirt particles
in pores, folds, and seams can have an abrasive effect and can
damage the leather surface as well as weaken seams.
The leather shou ld be c leaned regularly as needed. After having
been used for a relatively long time, your leather seats will acquire
a rich aged finish . This is a characteristic of natural leather and a
sign of true quality.
In order to maintain the value of this natural product over the life of
your vehic le , you should fo llow the recommendations below:
0 Note
• To keep your leather from bleaching out, do not allow it to be
exposed to bright sunlight for long periods of time. If you have to
leave the vehicle parked outside for long periods, cover the leather
to protect it from direct exposure to sunlight.
• Sharp objects on c lothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather.
[ i ] Tips
• After each time you clean the leather and at regu lar intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather. This creme wil l nourish and moisturize the
leather, helping it to breathe and stay supple . It also helps to build
up a protective coating on the surface .
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc . as soon as possible.
• Preserve the color of the leather as needed by using a special
colored leather care creme to touch up areas of uneven color .•

Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
-Clean soiled areas with a slightly moistened cotton or
woolen cloth.
More stubborn dirt
-More stubborn dirt can be removed using a cloth satu­
rated with a mild soap solution (2 tablespoons mild
liquid soap).
-Never allow the soap solution to saturate the leather, and
make certain that no water soaks into the seams.
Wipe off the soap solution with a soft, dry cloth .
Cleaning spots
-Remove fresh water-based spots (such as coffee, tea,
juices, blood) with an absorbent cloth or paper towel.
-Remove fresh grease or oil-based spots (such as butter,
mayonnaise, chocolate) with an absorbent cloth or paper
towel, or use the cleaner from the leather care kit if the
spot has not yet penetrated into the surface of the
leather.
-Use an oil/grease dissolving spray, if oil/grease spots
have dried on.
-Remove specific kinds of spots (ballpoint pen, felt
marker, fingernail polish, water-based paint, shoe polish,
etc.) with a spot remover specifically formulated for
leather. _.,

Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and the information
=> page 254. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine => &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
21 , or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well. It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: the engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=> page 265 . .,,_
21 Use only the corr ect cleaning solutions. Never use gasoline or diesel fuel.

that you fil l up at busy gas stations where the seasonal adjustment
is more likely to be made in time .
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fue l system.
• Do not use fuels that fail to meet the specified criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
b lend meets the specifications, ask your service station or its fuel
supplier.
• Do not use fuel for w hich the contents ca nnot be identified.
• Fue l system damage and performance problems resulting from
t he use of fuels different fro m those specified are no t the responsi ­
bility of Audi and are not covered under the New Vehicle or the
Em ission Control System Warranties .
• If you experience a loss of fue l economy or driveabi lity and
performa nce problems due to the use of o ne of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
depos it build-up caused by the type of gasoline you use.
A lthough gasoline grades differ from one manufacturer to another,
they have certain things in common. All gaso line grades contain
substances that can cause deposits to co llect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep engine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergen t Gasoline. For more
information on TOP T IER Detergent Gasoline, please go to the offi ­
cia l website (www.toptie rgas .com).
After an extended period of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .

Fuel supply and filling your fuel tank
Taking the fuel cap off
- To open the fuel filler flap, pull the button~ page 269,
fig. 200.
- Unscrew fuel filler cap counter-clockwise and hang it on the fuel filler flap.
Refuelling procedure
- Insert the fuel nozzle from the gasoline pump into the
fuel filler neck as far as it will go.
- 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 the MIL lamp => page 27to 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 car's filler neck could cause fuel
overflow and fuel spray. Fuel spray and overflowing fuel are
dangerous because they can cause fire or serious injury.
& WARNING (continued)
• 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.
• 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

• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember :
-We recommend using only coolant additive G12 + (check the
label) for your vehicle. This coo lant additive is avai lable at autho ­
rized Audi dealers . Other types of antifreeze can significantly
reduce corrosion protect ion. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do no t add any type of radiator leak sealan t to you r vehicle's
engine coolant . Adding radiator repair fluid may adversely affect the function and performance of your cooling system and could result
in damage not covered by yo ur New Vehicle Limited Warranty. •

The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
The tire pressure label located either on driver's side 8-pillar or
inside the fuel filler flap on your Audi lists the recommended cold
tire inflation pressures for the vehicle at its maximum capacity
weight and tires that were on your vehicle at the time it was manu­
fac tured .
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
~ & .
If your vehicle is equipped with a tire pressure monitoring system*,
bear in mind that the system can only monitor the tire pressures you have stored
. The system does not recognize the load condition of
your vehicle.
The effectiveness of the tire pressure monitoring system will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum
load~& .
See the illustration~ page 297, fig . 217 for the location of the label
either on driver's side 8-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change . In the event of discrepancies, the tire
pressure label (e ither on driver's side 8 -pillar or inside the fuel filler
flap) always takes precedence.
The table below lists the recommended cold tire inflation pressures
