could burn yourself. Let the engine cool off
first until you can no longer see or hear
steam or coolant escaping .
0 Note
- Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or high engine load, the engine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving . If the spoiler is damaged, this
could red uce the cooling effect and the en­
gine could then overheat. Ask your author­
iz ed Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You should shift to the next lowest gear when
the speed is below 1500 RPM . The beginning of
the red zone in the tachometer indicates the
maximum permissib le engine speed for all gea rs
once the engine has been broke n in. Before
reaching the red zone, you should shift into the
next higher gear, choose the Dor 5 selector lever
position , or remove your foot from the accelera­
tor pedal.
(D Note
The needle in the tachometer@Q
page 10,
fig. 3
may only be in the red area of the gauge
for a short time or there is a risk of engine
damage. The beginning of the red range in
the gauge depends on the engine operating
tern perature.
@ For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.
{!) Tips
The engine speed is limited when the engine
is cold - the full engine output is not availa­
ble. When the engine is at operating temper-
Instruments and indicator lights
ature, the red area in the tachometer moves
to a higher RPM range.
Fuel level
The fuel gauge only works when the ignition is
on. If the fuel level drops below 2.6 gallons (10
liters), the bottom LED turns red and the indica­
tor light
tD turns on Q page 20. The bottom
LED blinks red when the fuel level is very low .
The possible range based on the current fuel lev­
el is shown in tab@¢
page 22, fig. 4.
For the tank capacity in your vehicle, refer to the
Technical Data¢
page 260.
(D Note
Never drive until the tank is comp letely emp­
ty. The irregu lar supply of fuel that resu lts
from that can cause the engine to misfire. Un­
combusted fuel w ill then enter the exhaust
system. This can cause overheating and dam­
age to the catalytic converter .

CD Note
-Vehicle components such as the engine,
transm ission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determine the depth before driv ing through
water.
- Do not stop the vehicle, drive in reverse or
switch the eng ine off when dr iving through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
- Avo id d riving through salt water (corrosion).
Warming up and cooling
down
By carefully warm ing up and cool ing down your
veh icle, you can he lp ensure that it is not over­
stressed un necessa rily during sporty driving.
When warming up, the vehicle is dr iven at a max­
i mum eng ine speed of 6000 RPM in order to raise
the eng ine oi l temperature to a min imum of
140 °F (60 °C). The tires a lso on ly reac h their f ull
road ho ld ing capability once they have warmed
up .
The cooling fan can continue to run in your vehi­ cle after the engine is swi tched off. Howeve r,
d riving the vehicle to cool it dow n is particularly
important. D uring sporty dr iv ing, the engine and
brakes, the exhaust system, and the transmission
a ll become extremely hot. Before you park the
ve hicle, you shou ld drive it for a few m iles/kilo­
meters at light load in the low rpm range to al­
low it to cool down.
Driving and the envir onment
Catalytic converter
Applies to: veh icles w ith gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
.. Always use lead-free gasoline¢ page 198,
Fuel supply.
.. Never run the tank down all the way to empty.
.. Never put too much motor o il in yo ur engine
¢ page 20 7, Adding engine oil 9:::r. .
.,. Never try to pus h- or tow-start your veh icle.
The catalytic co nverter is an efficient "clean-up"
device built into the exhaust sys tem of t he ve hi­
cle. The catalyt ic conv erter b urns ma ny of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
po rtant fo r the life of the catalytic converte r and
prope r fu nct io ni ng of the eng ine.
_&. WARNING
The tempe ra tu re o f th e exh aus t sys tem is
hi gh, bot h when driv ing and a fter stopping
the engine.
- Never tou ch the e xhaus t tail pipes on ce they
have become hot. This cou ld res ult in burns.
- Do not p ark or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact w ith dry grass, b rush, fuel spill or
other mate rial which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l

Driving and th e en vironm ent
- Do not drive until the fuel tank becomes
complete ly empty . The engine cou ld mis­
fire . Unburned fuel could also get into the
exhaust system and this cou ld cause the
catalytic converter to overheat.
- Do not sw itch off the ignition while the vehi­
cle is moving.
- Do not continue to operate your vehicle un­
der these cond itions, as otherwise fuel can
reach the catalytic converter. This could re­
sult in overheating of the converter, requ ir­
i ng its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle maintained properly and
in accordance with the service recommen ­
dations in your Warranty
& Maintenance
book let.
- Lack of proper maintenance as well as im ­
proper use of the vehicle will impair the
function of the emission control system and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erating states. This depends on the sulfur
content of the fuel be ing used . Using a differ­
ent brand of fuel may help, or filling the tank
w ith lead-free super grade gasoline.
Placing your vehicle out
of service
If you would like to take your vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or authorized Audi Service Facility.
They will advise you of important measures, such
as corrosion protection, maintenance and stor­
age procedures. Also follow the information

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fuel economy, env ironmental impact, and wear
on your engine, brakes and tires large ly depend
on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percent. This section will
give you some tips on how you can help the envi­
ronment and your pocketbook.
(j) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehicle
l oad and speed, road and weather conditions,
trip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
~ Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are acceler­ ating. If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
erate less . Let the vehicle coast whenever possi­
ble -for example when you see that the next traf­
fic light is red.

Driving and the environment
The engine and catalytic converter have to reach
their optimal
operating temperature to reduce
fuel consumption and noxious emissions effec­
tively.
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 temperature and fuel
economy has reached a normal level. So you can
see that you should avoid short trips whenever
possible.
The
outside temperature is also critical in this re­
gard. Your car consumes more fuel in the winter
than in the summer .

Fuel and Refueling
Fuel and Refueling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lea se go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel wil l slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is availab le throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gaso line may not be available.
For more information on refueling your vehicle,
see
¢page 199.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
198
- Regular Grade: 87 - 90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Motor Octane Number.
{[) Note
-Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen ­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must not contain more than 15% etha-
nol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AK I or higher .
- Blend must contain not mo re than 1S% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you .,..

Fuel and Refueling
(D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter .
Refuelling
Fig. 177 Right rear vehicle side: Opening the fuel filler flap
Fig. 178 Fuel filler flap w ith attached fuel cap

fig. 178.
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.
200
Putting the fuel cap back on
.. After filling your tank, twist the fuel filler cap
clockwise as far as it will go.
.. 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 28 to come
on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns. -
- Fuel is highly flammable and can cause se­
vere burns and other injuries .
- Failure to shut the engine off while refuel­
ing 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 refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
- Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity 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 any­
where 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 exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can build up
