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 211, "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 222.
• 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 Warranty
& Maintenance
booklet.

one half. Never drive faster than the posted speed limit and weather
conditi ons permit. •
Reducing unnecessary Idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the eng ine run at
idle.
I t makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at railroad crossings, or at traffic lights that have long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle . However, wear and noxious emissions a re especial ly
high when the engine is warming up . So you should drive away as
soon as you start the engine and avoid running at high RPMs whi le
the engine is stil l warming up .
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idl ing also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .•
Regular maintenance
A badly tuned en gine unnecessarily wastes a lot of fuel.
- Have your v ehicl e serv ice d at reg ular intervals.
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
By having your vehicle regularly serviced by an Audi dea ler helps to
ensure that i t runs properly and economically . The conditio n of your
vehic le not only affects its safety and abi lity to hold its va lue, it also
affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load and speed .
I t is normal for the oi l consumption of a new eng ine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometres) be fore you can proper ly assess o il consumpt ion.
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with

booklet. Lack of proper ma intenance as well as improper use of the
vehicle wi ll impair the function of the emission control system and
cou ld lead to da mage.
• Do not alter or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do no t al te r or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your

Care of exterior
Washing
Frequent washing protects the vehicle.
Th e best protection against envi ronmental influences is frequent
washing and waxing .
H ow often t his is required depends on:
• H ow much the vehic le is used
• Where the vehicle is pa rked (garage, in the open under t rees,
etc.)
• The seasonal and weather conditions
• Environmental influences
T he longer bird droppings, insects, tree resin, road a nd industrial
grime, tar, soot, road salt and other materials remain on the vehicle
p aint, the more lasting their dest ructive effects will be . _,,,

•
High temperatures, as from exposure to intense sunlight, intens ify
the corrosive effect particularly when humidity is high as well.
Under ce rtain circumstances , weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the underside of the vehicle should be thoroughly
washed preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and the information
=> page 198 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However , the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
Before going through a car wash, be sure to take the usual precau ­
tions such as closing the windows. Remove antenna if applicable .
If you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be remov ed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 198. •

sha ped sp ray".
D o
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particula rly to the
operating
pre ssure
and the spraying di stance . Maintain a sufficient distance
to soft materia ls such as rubber hoses and sound/vibration dead ­
ening materia ls (part icularly on the underside of the engine hood).
Do not use a jet which sprays water in a
direct stream or one that
has a
rotating jet.
Water temperature should not exceed 140 °F (60 °Cl.
& WARNING
Never wash tire s with a jet that sp ra ys water in a dir e ct stream .
Thi s could cau se invisible damage to the tire s and we ake n them ,
eve n if th e spra y is from a re lativel y lo ng dis tanc e an d f or a sh o rt
time . Damaged and weakened tire s can f ail and cau se ac cident s
a nd per sona l injur y.
0 Note
To avoid damaging your vehicle, always make sure that there is
suffic ient distance between the spray head and soft materia ls like
rubber hoses, plastic parts and sound -deadening materials . Never
aim the spray head at the same p oint for a long time . This also
applies to cleaning headlights and painted bumpers . Remember :
the c loser the nozzle is to the surface of the material, the greater the
stress on the mater ial. •
