Natural nap pa leather is not covered by a color finish. It is therefore
more se nsitive to soiling and wear, which is something you need to
consider if children, animals or other factors might prove to be partic­
ularly hard on the leather.
By contrast, leathe r types that are covered by a colored finish layer
are more durable. This has a positive effect on the leather's resistance
to wear and so il ing in daily use. On the other hand, the typical charac­
ter istics of natural leather are barely or not apparent . However, this
does not mean that the le athe r itself is of inferior quality.
C ar e and handling
Beca use of the exclusive nature of the types of leather that Audi uses
and their unique properties (such as sensitivity to oils, grease, soiling,
etc.), yo u will need to be somewhat caref ul with these leathers, and
a certain type of care is requ ired . For example, dark clothing mate­
r ia ls can disco lor leather seats (espec ia lly if s uch clothi ng is damp and
was not dyed correctly) . Dust and d irt pa rticles in pores, folds, and
seams can have an abrasive effect and can damage the leather
surface as well as weaken seams.
The leather should be cleaned regu larly as needed. After having been
used for a relatively long time, yo ur leather seats will acquire a r ich
aged finish. This is a characteristic of natural leather and a sign of
t rue quality.
In order to maintai n the value of th is natural product over the life of
your vehicle, you should fo llow the recommendations be low :
0 Note
• T o keep your leather from b leac hing out, do not allow it to be
exposed to bright sunlight for long pe riods of time. If you have to
leave the vehicle parked outside for long periods, cover the leather to
protect it from direct exposure to su nlight.
• Sharp objects on clothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on t he
surface of the leather.
W Tips
• After each time you clean the leathe r and at regular intervals, use
a leather preservative cream that contains UV-blockers and that
wo rks into the leather. This cream will nou rish and moistu rize the
leather, helping it to breathe and stay supple . It also helps to build up
a protect ive coa ting 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 poss ible.
• Preserve the color of the leather as needed by using a specia l
colored leather ca re cream 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 so iled areas with a sligh tly mo istened cotton or
woolen cloth .
More stubborn dirt
- More stubborn dirt can be removed using a cloth satu­
rated with a mild soa p solution (2 tablespoons mild liquid
soap) .
- Never allow the soap solution to satu rate the leathe r, and
make certain tha t no wa ter soaks i nto the seams .
- Wipe off the soap solution with a soft, dry cloth.

Engine compartment
B e especi ally care ful w hen cleaning the engine comp art­
men t.
Always switch off the ignition before cleaning the engine=>& .
Plenum panel
Remove leaves from the plenum panel in front of the windsh ield
un der th e eng ine hoo d. This p revents the wate r drain holes from
becom ing b locked, and it prevents debris from entering the ve hicle
inter io r thr ough the heat ing and ventila tion ducts.
Corrosion protection
Th e engine compartment and tran smission have been cor rosion­
protected at the factory.
Goo d an ti- cor ros ion treatmen t is very impo rtan t, pa rtic ula rly in the
w inte r. If the vehicle is frequently driven on sa lt treated roads, t he
entire eng ine compa rtment and plenum pane l sho uld be thoroug hly
cleaned at the end of w inter and retreated to prevent sa lt damage . At
the same time, the underside of the vehicle should be washed as we ll.
If the eng ine co m par tment is clea ned at any time wi th grease
removing solutions
2l, or if you have the engine washed, the anti­
c o rrosion treatment is a lmost always remove d as we ll.
It is the refore
essential to have a long-last ing corrosion protect io n reapplied to all
s u rfaces, seams, joints and components in the engine compartmen t. ~

Fuel supply and filling your fuel tank Ill --------------'--':.......::-----=--=--------
Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well for
winter or summer driving. During seasonal change-over, we suggest
that you fill 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
corros ion 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 unab le to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
s u pplier.
• Do not use fue l for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi ­
bility of Audi and are not covered under the New Vehicle or the Emis­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveability and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended f uel. •
Gasoline additives
A major concern among many auto manufacturers is carbon depos it
build -up caused by the type of gasoline you use.
Safety first
Although gasoline grades differ from one manufacturer to another,
t hey have certain things in common. All gasoline grades contain
substances that can cause depos its to collect on v ital engi ne parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean, they
are not equally effective .
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended per iod of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .

& 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 electr icity before touching the filler nozzle again .
Static electricity can cause sparks that can ignite fuel vapors
released during refueling.
• Never smoke o r 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 except ional circumstances, you must transport a
portable fuel container , please obser ve 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.
Safety first
& WARNING (co ntinued )
-Alw ays 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 . Th is will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the veh icle 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 containe r meets industry standards
(ANSI/ ASTM F8S2-86).
0 Note
If any f uel has spilled onto the ca r, it should be remove d immed iate ly
to prevent damage to the paint.
As soon as the co rrectly operated nozzle switches off a utomat ica lly
for t he firs t time, the tan k is full. Do no t try to ad d mo re fuel because
fue l may spill ou t. In addi tion, the ex pansion space in the fuel tank
will be fi lled - causing the fue l to overf low w hen it becomes warm and
poll ute the enviro nmen t.
(I] Tips
• Runn ing your engi ne while re fuelling may c ause vapors to es cape
or even cause f uel to spill out of t he tank. This would then shut off the
fue l no zzle before the tank is full.
• Do not ref ue l your veh icle with t he ignit io n turned on . T he fuel
gauge may o therwise no t ind ica te t he correct f ue l level af ter refuel-

Closing the engine hood
-Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place . Do not try to
push it shut;
it may fail to engage=> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area
=> & .
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch: -Ignition cables
- Other components of the high voltage electronic ignition system.
• If you must perform a check or repair with the engine running: -First, fully apply the parking brake, move selector lever of
automatic transmission to "P" (Park). ..,

0 Note
• 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
coo lant 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 coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
eng ine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.

Vehicle OP-eration
Before you check anything in the engine compartment,
always read and heed all WARNINGS=:> & in "Working in
the engine compartment" on
page 280.
-Turn off the ignition.
- Let the engine cool down .
- Place a thick rag over the coolant expansion tank
=:> fi.9. 223 and carefully twist the cap counter -clockwise
=> & .
- Read the engine coolant level in the open coolant expan­
sion tank=:> fig. 223. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max" marking.
The location of the coo lant expansion tank can be seen in the engine
compartment illustration =>
page 281.
To obtain an accurate reading, the engine must be sw itched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor.
When the coolant level is too low, the warn ing light in the Auto-Check
System =>
page 31 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
t ime to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system . In the event of
coolant loss , the cooling system should be inspected immediately by
your authorized Aud i dealer . It is not enough merely to add coolant .
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating . .,

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.
With certain types of a irbag deployment, the battery is disconnected
from the vehicle electrica l system for safety reasons~
& in "Repair,
care and disposal of the airbags" on
page 213.
Disconnecting the battery terminals
Some vehicle funct ions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery termina ls are connected aga in . To
prevent this, the battery should only be disconnected from the
vehicle electr ica l system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not drive your veh icle over a period of several days or weeks,
electrical components are gradually cut back or switched off. This
reduces energy consumption and maintains starting capability ove r a
longer period
~ page 247.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or
powe r seat adjustment, may not be available. The convenience func ­
tions will be available again when you turn on the ignition and start
the engine.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often .
Avoid unnecessary power consumption, particu larly in city traffic or
when travel ing only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 293. A well charged battery will not only p revent start ing
problems when the weather is cold, but will also last longer.
Safety first
(I] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery shou ld be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the
battery.
The battery is located in the luggage compartment under the
floor. Before you check anything in the lu~gage compart­
ment,
read and heed all WARNINGS =:,& .
Always heed the safety warnings, when working on the vehicle
