Winter tires
When driving in the winter, your vehic le with All Wheel Drive has an
advantage, even wi th regula r t ir es . In winter road conditions it may
be advisable to mount winter tires (or all -season tires) for improved
driveabi lit y an d braking : these tires m ust be mounted on
all four
wheels .

-Road driving?
Your Audi d oes not have en ough gr ound clea rance to be use d as a n
off -road vehicle. It is therefore best to avoid roug h tracks and
u neven terrain as much as possible. A lso refer to=>
page 194.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks .
• Although the All Wheel Drive is very effective , always
remember that braking capacity is limited by tire traction. You
should therefore not drive at e xcessive speeds on icy or slippery
road surfaces.
• On wet road su rfaces , be careful not to dr ive too fast because
the front wheels could begin to slide on top of the water (aqua ­
planing ).
If this should occur , you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
vehicle . Always d rive at speeds which are suited to the road condi­
tions. -risk of cra sh. •

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometres) after they
are installed.
New brake pads have to be "burnished in" before they have optima l
grab=> &.
During the break -in period, you should avoid putting severe loads
on the brakes. Severe loads include, for example, sudden hard
braking, in particular at very high speeds or, for example, on moun ­
tain passes.

Catalytic converter
It is very important that your emission control system
(catalytic converter) is fu nctioning properly to ensure that
y o ur vehicle is running in an environmentally s ound
manner.
- Always use lead-free gasoline~ page 214, "Fuel supply".
- Never run the tank down a ll the way to empty.
- Never put too much motor o il in your engine~

Dri
ving and environm ent
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle . The cataly tic converter burns many
of the pollutants in the exhaust gas before they are re leased into the
atmosphere.
The exclusive use of un leaded fuel is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or oper ate th e ve hi cle in are a s whe re the hot
exha ust sys te m may c ome in conta ct wi th dr y grass, bru sh , fu el
s pill or other mat eri al which can cau se a fi re.
• Do not app ly a dditi onal u nder co at ing or ru stpr oofing on or
near the exhau st m anifold , exh au st pipe s, cata ly tic convert er or
he at shi elds. During dri ving, the s ubstance use d f or und ercoa ting
c ould ov erheat an d ca u se a fire.
0 Note
• Be aware that just one tank fi lling with
le ad ed fuel wi ll a lready
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level =>
page 225.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire . Unburned fuel could a lso get into the exhaust
system and this could cause the catalytic converter to overheat .
• Do not turn off the igni tion wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fue l can reach the cata lytic converter. This could resu lt
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emiss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance & Warranty
booklet.

The engine and catalytic converter have to reach their optimal oper­
ating temperature
to reduce fuel consumption and noxious emis ­
sions effectively.
• Just after starting, a cold engine in a mid -size car burns the fuel
at a poor rate of 6-8 miles per gallon (30-40 l/100kml. Half a mile
down the road, the mileage improves to 12 MPG (20 1/100 kml. It will
take the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operating temperature and operate at an
economic mileage. This explains why taking the car for short trips is
a rather wasteful convenience.
• The
outside temperature is also critical in this regard. Your car
consumes more fuel in the winter than in the summer.
Trailer towing
General information
Your Audi TT Roadster is not designed to tow a trailer.
Towing a trailer with your Audi TT Roadster is not recommended
and can cause damage to the car. Damaged caused by towing a
traile r is not covered by your Audi Warranty. •

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 should be cleaned 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 vehicle, you should follow 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 clothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather.
[ i J Tips
• After each time you clean the leather and at regular intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather. This creme will 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. •
Applies to vehicles: w ith natu ral leather
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. ..,_

& WARNING (continued)
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation , causing loss of control
and a crash .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct
Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard (tire infla­
tion pressure label)=;>
page 242, fig. 160.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
Tires and wheels 1111111
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker =;>
page 242, fig. 160.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will be five 150 lbs. passengers in your
vehicle, the amount of available cargo and luggage load capacity is 650 lbs.
( 1400 -750 (5 x 150) = 650 I bs.)
5. Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load ca pa city calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle. .,_
