mph/ 10 km/h.
A WARNING
- Never turn off the engine before the ve
hicle has come to a complete stop . The
full function of the brake booster and the power steering is not guaranteed . You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P . Otherwise, the vehicle could inad
vertently roll away.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment.
- Always take the key with you whenever you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri
ous inJury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es
caping from the vehicle on their own in
the event of an emergency. Depending
on the time of year, people inside the ve hicle can be exposed to very high or very
low temperatures.
(D Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine is switched off -there is a risk of damaging
the engine. Allow the engine to run at idle
for about two minutes before switching it
off .

Fa u lts in th e brake sy stem

.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat
ings w ill be cleaned off after a few care
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in
creased stopping distance . Avoid driving
the vehicle and have it towed to the near
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

206 Driving and en vir onm ent
Catalytic converter
It is very important that your emission con
trol system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
• Always use lead-free gasoline¢ page 228,
Fuel supply.
• Never run the tank down all the way to
empty .
• Never put too much motor oil in your en-
gine ¢
page 238, Adding engine oil~-
., Never try to push- or tow -start your veh icle.
The catalytic converter is an eff ic ient "clean
up" device built into the exhaust system of
the vehicle. The catalytic converter burns many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
important for the life of the cata lytic conve rt
e r and proper functioning of the engine.
& WARNING
-
- Do not park o r operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con
verter or heat shields . During driving, the
substance used for undercoating could
overheat and cause a fire .
@ Note
-Be aware that just one tank filling with
leaded fuel will already seriously de
grade the performance of the catalytic
conve rter .
- Do not exceed the correct engine oil level
¢ page 238.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned f uel could a lso get into the exhaust system and this co
uld cause
the cata lytic converter to overheat .
- Do not turn off the ignition while the ve
hicle is moving.
- Do not continue to ope rate your veh icle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
cou ld result in overheating of the con
verter, requir ing its replacement.
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained properly
and in accordance w it h the service rec
ommendat ions in your Warranty &
M ain tenance book let.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle will impair
the function of the em iss ion contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing proper ly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or f il li ng the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are d rivi ng on poor roads, or over
c u rbs, steep ramps, etc., ma ke certai n that
low- ly ing parts s uch as spoilers and exha ust
system parts do not bottom o ut and get dam
aged.
T his is espe cially true for ve hicles with low
s lung chassis (spor ts chassis)* and fully load
ed vehicles .

208 Driving and environment
would go unheeded. Extended idling also
produces heat, which could result in over heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
• Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ability to hold its value, 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.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess oil consumption .
This also applies to fuel consumption and en
gine output .
{Q) Note
-Have your vehicle maintained properly
and in accordance with the service rec
ommendations in your Warranty
& Main
tenance booklet. Lack of proper mainte
nance as well as improper use of the ve
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and
other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips.
• Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 miles
per gallon (30-40 l/100 km). After about a
half a mile , fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operating tempera
ture and fuel economy has reached a normal level. So you can see that you should avoid
short trips whenever possible .
T he
outside temperature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer .

226 Cleaning and protec tio n
• Remove specific kinds of spots (ballpoint
pen, felt marker, fingernai l polish, water
based paint, shoe polish, etc .) with a spot
remover specifically formulated for leather .
Leath er care
• Every ha lf year use an approved leather care
product (available from your authorized
Audi dealer) to care for the leather.
• Apply the product very sparing ly.
• Wipe it off with a damp cloth.
If you have any questions about cleaning and
caring for the leather in your vehicle, it is best
to contact your author ized Audi dealer, who
will be glad to help you and tell you about our

-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 stat ions where the sea
sonal adjustment is more likely to be made in
time.
(D Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in veh icles with flex ible fuel* en
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l* engines
can cause severe engine damage .
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo
nents in the fuel 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 particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel 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 respons ibility of Audi and are not
covered under the New Veh icle or the

Fuel supply and filling your fuel tank 229
Ethanol fuel (Bio-ethanol)
Applies to veh icles: w it h flex ible fue l en gin e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap .
Vehicles with flexible fuel engines may be op
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un
leaded gasoline (91 AKI/ROZ 95) . T he vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in ve ry
low temperatures. This fuel evaporates again
when the engine is warmed up.
D Please warm up engine.
If the driver message appears in the instru
ment cluster disp lay, drive with a warm en
gine to reduce the oil level.
(D Note
- Never fill with methanol or with a higher
percentage of b io-ethanol than 85%
(E85). A h igher percentage of bio-etha
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fue l tank complete ly w ith un
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fuel tank comp letely with unleaded pre
mium grade gasoline and dr ive it nor
mally until the gasoline is used. See your
authorized Audi dealer if the problem
pers ists.
