10 Instrum ents a nd warning /indic ato r li ghts
Stop the vehicl e, sw itch the engin e off and
allo w it to coo l.
If the warning light comes on
again after driving a short distance, contact
an authorized Audi dealer.
A WARNING
- Always observe the warning in
¢ page 169, Working in the engine
compartment
before open ing the engine
compartment lid and checking the en­
gine coo lant level.
- Never open the engine compartment lid
if you see or hear steam, or if you see en­
gine coo lant dr ipping from the eng ine
compar tment. You could bur n yourse lf.
Let the engine coo l
off first so that you
cannot hear or see any steam or engine
coolant.
CD Note
- Mounting additional lights or accesso ries
in front of the air inlets reduces the cool­
ing effect of the radiator . At high outside
temperatures or high engine load, the
engine could overheat .
- The front spoi ler has been designed to
properly distribute the cooling air when
the vehicle is moving. If the spoiler is
damaged, this could reduce the cooling
effect and the engine could then over­
heat . Ask your authorized Aud i dea ler for
ass istance.
Fuel gauge
The fuel ga uge works only when the ignition is
on. When the needle reaches the red area, the
warning light in the instrument cluster will i l­
luminate
c::> page 18 Ii}']. This means you
have approximately 2.6 gallons (10 liters) of
fuel left in the tank.
Time to refuel!
The total tank capacity of your vehicle is listed
in
Te chnic al d ata c::> page 217 .
CD Note
Never run the tank comple tely d ry! An ir­
regular supply of fue l can cause engine misfiring and fuel could enter into the ex­
haust system. The catalytic converter
could then overheat and be damaged.
Speedometer with odometer
The speedometer shows you the vehicle
speed, and the odometer shows you how
many miles (kilometers) you have driven.
F ig. 5 Speedomete r close-up: odometer display
The distance dr iven is shown in m iles (USA
models) or in kilometers (Canada mode ls) .
Lo wer odometer
The lower odometer shows the total number
of miles (kilometers) dr iven .
Upper odom ete r (trip odometer )
The upper odometer shows the total number
of miles (kilometers) driven since you last re­
set the odometer back to zero. You can use
this odometer when you want to keep track of
how many m iles (kilometers) you have driven
for a single tr ip or errand . The last dig it ind i­
cates 1/10 of a mile (100 meters) . You can set
the tr ip odometer back to zero by pressing the

current and average fuel mileage , average
spe ed, fuel range and driving time.
Fi g. 10 Tri p co mpute r 1
You can switch between the trip computer 1
and 2 by pressing the
! R ES ET I button @
qpage 24, fig . 11 .
You can te ll wh ich memory leve l is currently
active by the number in t he disp lay ¢

from the to tal -tr ip memo ry is being displayed
(memory level 2).
Single-trip memory (Trip computer 1)
The single-trip memory stores the tr ip infor ­
mation from the time the ig nitio n is turned on
u nt il it is turned off .
If the trip is cont inued
within 2 hours fr om the time the ignition was
turned off, the new data will be in cl ud ed in
the calculat io n of the current tr ip in forma­
tion . If the trip is interr upted fo r
more than 2
hours
the memory is reset automatically. .,..

-Have you r vehicle maintained properly
and in accordance with the service rec­
ommendat ions in your Warranty
& Main­
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys­
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv ­
ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or­
der to raise the engine oil temperature to a minimum of 140 °F (60 °(). The tires also on­
ly reach their full road holding capability once
they have warmed up.
The cooling fan can continue to run in your ve­ hicle after the engine is switched
off. H owev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become extreme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex­
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera­
tion
¢ page 17 4 .
You shou ld definitely inspect your vehicle af­
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 151
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work­
shop will be happy to undertake an inspection
before and after use on the race track.
_& WARNING
-
Some race tracks (e.g. steeply banked
turns) may affect the response of the ESC.
(D Tips
- Review the track requirements and con­
ditions before you start driving.
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re­
sult in increased wear.
Operation and maintenance
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires la rgely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
By havi ng your ve hicle reg ularly se rviced by an
a uthorized Aud i dea le r helps to ens ure that i t
runs properly and economica lly. The condition
of your vehicle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
consumption .
The amount of oi l used is re lated to engine
load and speed .
It is normal for the oil consump tion 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
(5,000 kilometers) before yo u can p rope rly
assess oil consumpt io n.
Th is also app lies to fue l consumption and en-
gine o utp ut.

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll 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
-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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- 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 l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
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 supply and filling your fuel tank 165
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.
Q) Note
Damage or malf unct ion due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see
¢ page 167.
You can find the fuel tank capacity of your ve­ hicle in
Technical Data ¢ page 217.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see
¢ page 164.
Your vehicle fue l tank has an on -board refue l­
ing 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
properly while protecting the environment,
please fo llow 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 f uel can be dangero us. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
AS TM F852 -86).
(D Note
Never drive your vehicle until the fuel tank
is completely dry. The irregular supply of
fuel can cause misfir ing. Gasoline cou ld

Refueling
Fig. 133 D river 's doo r: Unlocki ng fuel filler flap
Fig. 134 Fuel cap hooked on the opened fuel filler flap
When adding fuel, the ignition and any cellu­
lar phones in the vehicle must be sw itched
off .
Tak ing th e fuel cap off
• To open the fuel filler flap, press the button
9fig. 133.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filler flap ¢
fig. 134 .
Refueling procedure
• Insert the f uel nozzle from the gasoline
pump into the fuel fi ller neck as far as it wi ll
go .
• Select a med ium refueling rate so that the
nozzle switches off automatically when the
tank is full.
Putting th e fu el cap bac k on
• After fi lling your tank, twist the fuel filler
cap clockwise until you hear a definite click.
• Close the fue l filler flap.
T o avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly and completely. An improperly closed fuel fi ll­
er cap may also cause the MIL lamp¢
page 22
to come on.
A WARNING
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Fai lure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to ove r­
flow. F ue l spray and overflowing fuel can
cause a fire.
- Never use a ce llular telephone while re­
fue ling. The electromagnet ic rad iat io n
can cause spa rks that can igni te fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fue ling.
If in exceptio nal circumstances
you must get back in your vehicle while
ref ueling, make certain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
re leased d uring refueling .
- Never smoke or have an open f lame any­
where in o r near your veh icle when refu­
eling or filling a portable fue l conta iner.

-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con­
tainer, 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 example, in the luggage compart­
ment, or on the trunk) . Static electrici­
t y can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling .
- Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container . This will
help prevent static electricity from dis­
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin­
cial laws regarding the use, storage
and transportation of fuel containers
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86).
(D Note
I f any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle switches off automatically for the first
time, the tank is full. Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fuel to
Fuel supply and filling your fuel tank 167
overflow when it becomes warm and pol­
lute the environment.
a) Tips
- Running your engine while refueling may
cause vapors to escape or even fuel to
spill out of the tank. This would then
shut off the fuel nozzle before the tank
is full.
- Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refueling .
Unlocking the fuel filler flap

184 Tire s and wheel s
-Ne ver mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry. " Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight means t he comb ined we ight (in excess of
those standard items which may be rep laced)
of R t ron ic, powe r stee ring, powe r brakes,
power w indows, power sea ts, r ad io, and hea t­
e r, to the extent that these i tems are available
as facto ry -in stalled equipment (whether in ­
stalled or not).
Aspect ratio
means t he ratio o f the he ight to the w idth of
the tire in percent. Numbers of 55 or lower in ­
d icate a low sidewall fo r improved s teer ing re ­
sponse and better overall handling on dry
pavement.
Bead
means t he part of the tire that is made o f
steel wires, wr apped o r reinforce d by p ly co rds
and that is shaped to fi t the r im.
Bead separation
means a b reakdown of the bond between
compo nents in the bead.
Cord means the strands forming the plies in the
tire.
Cold tire inflation pressure
means t he tire pressure recommended by the
ve hicle manufacturer for a tire of a designated
size that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure i s measu red or adjusted. -
If you notice un usual vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­
age.

axle system, measured at the tire-ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum tota l loaded we ight of
the vehicle.
Groove
