Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first
350 miles (500 kilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water . ""

Driving and th e environment
(D Tips
- Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Catalytic converter
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 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of the vehi­
cle. The cataly tic converter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The ex clusive use of u nleaded fuel is critically im­
por tant for the life of the catalyt ic converte r and
p roper functioning o f the engine.
A WARNING ,..___ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park o r operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter or
heat shields. During driv ing, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank fill ing with
le ad·
ed
fue l w ill already ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine co uld m isfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lyt ic converter to overheat.
- Do not turn
off the ignition while the vehicle
is moving .
- Do not continue to operate your veh icle un­
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re­
sult in overheating of the conve rter, requ ir­
ing its replacement.
- T o assure efficient operation of the Emission
Cont ro l System:
- Have your vehicle maintained properly and
in accordance with the se rvice recommen­
dations in yo ur Warranty
& Maintenance
booklet.
- Lack of proper maintenance as we ll 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 Emiss ion C ontrol System is op­
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme ll under some op­
erat ing states. This depends on the sulfur
content of the fuel being used. Us ing a d iffe r­
ent brand of fue l may he lp, or fi llin g the tank
wi th lead-free s uper grade gaso line.
Shutting down vehicle
If you would like you r vehicle to remai n inope ra­

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.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your persona l dr iving 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 percen t. This sec tion will
give you some tips on how you can help the envi ­
ronment and your pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depending upon vehicle load 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 accelerating 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
e rate less. Let the vehicle coast whenever possi­
ble - for example when yo u see that the next traf­
fic light is red .
Driving and the environment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fuel consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when wa iting for tra ins to pass a t railroad
crossings, or at traffic lights that have long waits
on red . Turning the engine
off for just 30-40 sec ­
onds saves more fue l than is burned starting the
. . engine again.
It takes a long t ime for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high when
the engine is warming up. So you should drive
away as soon as you sta rt the engine and avoid
running at high rpms wh ile the engine is st ill
warming up.
(D Note
Do not leave engine idling unatt ended afte r
starting .
If warning lights should come on to
indicate improper operation, they would go
un heeded . Extended idling also produces
heat, which could result in overheating or oth­
er damage to the vehicle or other property.
179

Driving and th e environment
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.,. Have your vehicle serviced at regula r intervals.
By having your vehicle regularly 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 ability to hold its value, it also affects
f uel c onsump­
tion .
C he ck you r oil e ach t ime you fill you r ta nk .
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
g ine to reach its lowes t va lue after a cer tain mile ­
age has been d riven .
You must d rive you r vehicle about 3,000 miles
(5 ,000 k ilometers) before you can properly as­
sess o il cons umption .
This a lso applies to fuel consumption and engine
output.
(D Note
- Have your vehicle maintained properly and
in accordance w ith the service recommenda­
tions in you r Warra nty
& M aintenance book­
l et . Lack of p roper m aintenance as well as
i mprope r use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not a lter or remove any component of
the Emission Cont ro l System unless ap­
proved by the manufacturer.
- Do not a lter o r remove any dev ice, such as
heat shie lds, switches, ignition wires,
va lves, which are designed to protect your
vehicle's Emiss ion Control System and other
i mportant veh icle components.
180
· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid dr iv ing short distances with a cold
eng ine .
The eng ine and catalytic converter have to reach
their opt imal
oper atin g temperature to reduce
fuel consumpt ion and noxious emissions effec­
tively .
Just after starting, a co ld engine in a mid-s ize 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), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avo id short trips whenever
poss ible .
The
out side t emp eratur e is also cr itical in th is re­
gard. Your car consumes more fuel in the winter
than in the summer.

Fuel and Refueling

Fuel
Fuel supply
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,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine 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 AKl/91
RON octane fue l will s lightly reduce eng ine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 188.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine damage and a loss
of engine 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
- Regular Grade: 87 -90 AKI
186
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will 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
Use of gasoline containing alcohol or MTBE
( methyl tertiary butyl ether)
You may use unleaded gasoline blended with a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts 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 1S% etha-
nol.
- Veh icles with flex ible fuel engine: blend must
not contain more than 85% ethanol.
Blend of gasoline and MTBE
-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 es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you ""

M N
i? co ,...., \!) 1.1'1
N 1.1'1 ,....,
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time.
(D Note
- Fuels containing a high pe rcentage of etha­
no l such as ESQ and E85 may only be used in
vehicles with f lexible fuel engines. Using
high ethanol fuel in veh icles not equ ipped
with flexible fuel engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter .
- If you are unable to determine whether or
not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier .
- Do not use fuel for wh ich the contents can­
not be identified.
- Fuel system damage and performance prob­
lems resulting from the use of fuels differ­
ent from those spec ified are not the respon­
s ibility of Audi and are not covered under
the New Vehicle o r the Emission Cont ro l
System Warranties.
- If you experience a loss of fue l economy o r
driveability and pe rformance problems due
to the use of one of these f uel b lends, we
r ecommend that yo u switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to vehicles: with flexible fuel engine
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Vehicles w ith f lexible fuel engines may be operat­
ed with bio-ethanol fuels such as E85 (85% e tha ­
nol and 15% gasoline) or with unleaded gasoline
(91 AKI/ROZ 95) . The vehicle may also be operat­
ed with a m ixt ure of these fuels.
Fu el and R efu elin g
Your f uel consumption wi ll increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy contained per unit vo lume in ethano l.
Warming up the fle xible fuel engine in low
t e mperatu res
Due to the chemical composition of b io-ethanol,
a certain amount of fue l ends up in the engine oil
when driving short distances in
very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up .
II Please w arm up eng ine .
If the driver message appears in the instrument
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
-Never fill with methano l or with a h igher
percentage of b io-ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fue l can cause damage to the engine or to
the fuel system.
- If you use on ly E85, it is recommended to
fill the fue l tank complete ly w ith unleaded
premium grade gasoline every 5,000 miles.
- If you experience starting, rough id le or hes­
itat ion driveab ility problems, fill the fuel
tank complete ly w ith unleaded premium
grade gasoline and drive it normally unt il
the gaso line is used. See your author ized
Audi dea ler if the problem pe rsists.
- Inform your author ized Audi dealer that you
are operating or have operated the vehicle
w ith E85.
- Read and follow the information and t ips
about gasoli ne
c::> page 186 .
(D Tips
It may take longer to start the engine when
the outs ide temperature is
very cold. If possi­
ble, use winte rized fue l if tempe ratu res are
below free zin g.

Fuel and R efue lin g
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP T IER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi­
cle Limited Warranty .
- Do not add aftermarket f uel addit ive prod­
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc­
tions seer:>
page 190 .
You can find the fue l tank capacity of your vehicle
in
c:>page242 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fue l specifications, see
c:> page 186 .
Your vehicle fuel tank has an on -board refuelling
vapor recovery system . This feature helps to pre­
vent fuel vapors from escaping from the tank and
188
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l containers . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

A WARNING
Improper refueling or handling of fue l can
cause fire, exp losion and severe burns.
-
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off whi le refuel­
ing and/or to insert the pump nozzle fu lly
into the fuel filler neck could cause fue l to
spray out of f iller neck or to overflow. Fuel
spray and overflow ing fuel can cause a fire.
- Never use a cellular telephone wh ile 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 c ircumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch meta l to discharge static e lectric­
ity before touching the filler nozzle again.
Fu el and R efu elin g
Static electricity can cause sparks that can
ignite fuel vapors released during refue ling.
- Never smoke or have an open f lame any­
where in or near your vehicle when refueling or filling a portable fuel conta iner .
- For your safety, we strongly recommend
that you do not travel with a portable f uel
container in your veh icle. The container, full
or empty may leak and cou ld cause a fire,
especially in a crash .
- If, under exceptional c ircumstances, you
must transport a portab le 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 l uggage compartment, or on
the trunk). Static e lectric ity can build up
while filling and can ignite fuel vapors
caus ing a fire .
-Always place a portab le fue l conta iner on
the ground before fill ing .
- Always keep the filler nozzle completely
inside the portable container before and
during f il li ng.
- If filling a portab le container made of
metal, the f iller nozzle must always be in
contact with the container. This will help prevent static electricity from d ischarging
and cause a fi re.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable.
- Always observe local and state/provincial
laws regarding the use, storage and trans­
po rtation of fue l conta iners.
- Make certain the fuel conta iner meets in­
dustry standards (ANSI/ AS TM F852 -86).
