- Have your vehicle main tained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating properly, the exhaust gas can have a sulfur-like exhaust gas smell under
some operating states. This depends on
the sulfur content of the fuel being used.
Using a different brand of fuel may help,
or filling the tank w it h lead-free super
grade gasoline.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
e rat ive for a longer period of time, con tact an
Aud i or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro­
sion prevention, maintenance and storage. Pay attention to add itiona l information con­
cerning the battery. Refer to

Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors:
- yo ur persona l dr iving style
- operating conditions
- tec hnic al lim itations
If you anticipate what you need to do next and
d rive economically, you can eas ily cut your
f u el cons umption by 10 -15 pe rcen t. T his sec- t
ion w ill give you some tips on how you can
help the environment and your pocketbook .
(D Tips
The cons umption estima tes as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will va ry depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating .
.. Avo id u nnecessary accelerating and brak ing.
Vehicles use the most fue l when they are ac­
ce lerat ing. If you ant icipate what is going to
happen next, you wi ll need to brake less and,
t h us, acce lerate less . Let the veh icle coast
whenever possible -for example when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maximum
speed.
Acce lerat ing gently red uces fue l cons ump­
t ion, eng ine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionate ly at h igh
speeds. If you drive at approximately three quarters of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
than the posted speed limit and weathe r con­
ditions pe rm it.

Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driving
the vehicle.
11-Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at rail­ road cross ings, or at traffic lights that have
long wa its on red. Turning the engine
off for
just 30-40 seconds saves more fue l than is
burned s tarting the eng ine again.
It takes a long time for the engine to warm up
fully when it is running at idle . However, wear
and nox ious em issions are especially 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 while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld 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 .
11-Have your vehicle serviced at regular inter-
vals.
By having your vehicle regular ly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab ility to hold its value, it also affects fuel
co nsumpt ion .
Ch eck you r oil each time you fill you r ta nk .
Dri vin g and en vironm ent 191
The amount of oi l used is re lated to engine
load and speed.
It i s normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before yo u can properly
assess oil consumpt ion.
Th is also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
& Ma in­
t enance book let. Lack of p roper mainte ­
nance as well as improper use of the ve­
hicle will impair the function of the
emission cont ro l 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 shie lds, 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 .
11-Try to avoid driving short distances w ith a
cold engine.
T he engine and cata lytic converter have to
reach their optimal opera ting temp era ture to
reduce fuel consumpt ion and noxious em is­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 mi les
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), liJI,

Fuel recommendation
The fuel recommended for you r vehicle is un­
leaded premium
g rade gasolin e. A udi recom­
mends us ing TO P TI ER D etergent Gaso line
w ith a m inim um octane ra ting of 91 A KI ( 95
RON ). Fo r more inform ation on TOP TIER De­
tergent Gasoline, please go to the off ic ial
website (www.toptie rgas .com) .
The re commended gasoline octane rating for
your en gine can also be fo und o n a label loca t­
ed on t he ins ide of the fuel filler flap . This ra t­
ing may be specif ied as AKI or RO N.
Your veh icle may al so be operated using un­
l e aded regular g asoline w ith a min imum o c­
tane rating of 87 AK I/91 RO N. However, using
87 AK I/91 RON octa ne fue l w ill sli ghtly re­
d uce eng ine perfo rmance .
Use unleaded ga solin e only. Unleaded g aso­
line is available th rougho ut the USA, Ca nada,
and i n most E uropean countries . We recom­
mend that you do not ta ke yo ur vehicle to
areas or co untries where unleaded gasoline
may not be ava ilable.

Explanation of the abb reviations :
AKI = Anti Knock Index = (R+ M)/2 = (RO N
+M ON)/2
RON = Research Octane Num ber
M ON = M otor Octane Number.
@ Note
- Do not use a ny fue l w it h octane rat ings

202 Fuel supply and filling your fuel tank
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 sea­
sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only be used in vehicles with flexible fuel en­
gines. Using high ethanol fuel in vehicles not equipped with flexible fuel 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 responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flexible fuel e ngi ne
You con 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 (8S% ethanol and
15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fuels 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 bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- If you use only E85, it is recommended
to fill the fuel tank completely with un­
leaded premium grade gasoline every
5,000 miles.
- If you experience starting, rough idle or
hesitation driveability problems, fill the
fuel tank completely with unleaded pre­ mium grade gasoline and drive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists.
- Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline
c::> page 201. .,.

@ Tips
It may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine 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 effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIE R
Detergent Gasoline, please go to the officia l
website (www.toptiergas .com) .
Afte r an extended pe riod of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.
CD Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty.
- Do not add aftermarket fuel additive
products to your fuel tank.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the r ight rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can sti ll open the flap manually - for detailed
instructions see
c:> page 205.
You can find the fue l tank capacity of your ve ­
hicle in
c:> page262.
Fuel supply and filling your fuel tank 203
The label on the inside of the fuel fi lier f lap
te lls you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c:> page 201.
Your vehicle fue l tank has an on -board refue l­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fill the tank
proper ly while protecting the environment,
please follow this refueling procedure careful­
ly.
_&. WARNING
Under normal operating conditions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, fu ll or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
CD Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregu la r supply
of fue l can cause misfiring. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.
