Driving and the
environment
The first 1,000 miles (1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first
1,000 miles (1 ,500 km) .
For the fir st 600 mil es
(1,000 kilometers):
.,. Do not use full throttle.
.,. Do not drive at engine speeds tha t are more
than 2/3 of the max imum permitted RPM .
.. Avoid high engine sp eeds .
From 600 to 1,000 mile s (1,000 to
1,500 kilometers):
.. Speeds can gradually be increased to the
max imum pe rm iss ib le road or eng ine speed .
During and after break-in per iod
.,. Do not rev the engine up to high speeds
when it is cold. Th is app lies whether the
transmission is i n N (Ne utra l) or in gear.
After the break- in period
.. Do not exceed maximum engine speed un­
der any circumstances.
.,. Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ome ter scale
¢ page 10.
During the first few hours of driving, the en­
g ine's interna l friction is higher than later
when all the moving parts have been broken
i n. How well this break-i n process is done de­
pends to a conside rable extent on the way the
ve hicl e is driven d uring the first 1,0 00 miles
(1 ,5 00 k ilome ters).
(D Note
Extremely h igh engine speeds a re auto­
ma tica lly reduced. However, t he se rpm
lim its are pr ogr amme d for an eng ine well
r u n- in, not a new engine .
Driving and the environment 193
@) For the sake of the environment
Do not drive with unnecessar ily hi gh en­
g ine speeds -upsh ifting ear ly saves f uel,
r educes noise and protects the environ­
ment.
New tires
If your vehicle is running on new tires, drive
particularly caref ul for the first 350 miles
(500 kilomete rs) afte r fitt ing.
.&, WARNING
N ew tires tend to be slippery and mus t al­
so be "b roken -in" . Be s ure to remember
this dur ing t he f irst 350 m iles (500 kilo­
meters) . Brake gently . Avoid fo llow ing
closely behind other vehicles or other sit­
uations that m ight require sudden, hard
b raking .
New brake pads
Remember that new brake pads do not have a
full brak ing effect dur ing the first 250 m iles
(400 kilomete rs) afte r they a re install ed.
New brake pads have to be "burnished in" be­
fo re they have optima l grab¢ .&. .
D uring the brea k-in pe riod, you should avo id
putting severe loads on the brakes. Severe
l oads include , for example, sudden hard brak­
i ng, in particular at very h igh speeds or, for
example, on mounta in passes .
.&, WARNING
New b rake pa ds don 't have the best stop­
p in g p ower a nd must be "b ro ken -in " dur­
ing the ini tial 1 00 to 150 miles (15 0 to
2 00 kilometers) o f no rma l ci ty driving . You
can compensate for this by pressing t he
b rake peda l more fi rm ly . This also applies
l ater when new pads are installed.

194 Driving and the environment
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water or mud, the
braking effect can be reduced due to mois­
ture on the brake discs and brake pads. A
few careful brake applications should dry off the brakes.
@) Note
Vehicle components such as the engine, transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determ ine the depth before driving
through water.
- Do not stop the vehicle, 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 vehi­
cle to drive through safely.
- Avoid dr iving through salt water (corro­
s ion).
Catalytic converter
App lies to vehicles: with gasoline engine
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 gaso line¢ page 206,
Fuel supply .
> Never run the tank down all the way to emp-
ty.
> Never put too much motor o il in your engine
¢ page 215, Adding engine oil > Never try to push- or tow -start your vehicle .
The catalytic converter is an efficient "clean ­
up" device built into the exhaust system of
the vehicle . The cata lytic 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 critica lly
important for the life of the catalytic convert­
er and proper functioning of the engine.
A WARNING
-
The temperature of the exhaust system is high, both when driv ing and after stopping
the eng ine .
- Never touch the exhaust tail pipes once
they have become hot . This could result
in burns.
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substance used for undercoating could
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢page 215.
-Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire . Unburned fuel could also get into
the exhaust system and this cou ld cause
the catalytic converter to overheat.
- Do not switch off the ignition while the
vehicle is moving.
- Do not continue to operate your vehicle
under these conditions, as otherwise fuel
IIJ,,

can reach the catalytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System :
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@) For the sake of the environment
Even when the Emission Cont ro l System is
operating properly, t he exhaus t gas can
have a s ulfu r-like exhaust gas smell unde r
some operating states. This depends on
the s ulfur content of the fue l being used .
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline.
Placing your vehicle
out of service.
I f you wou ld like to take your vehicle out of
service for a longer t ime, contact your aut hor­
iz ed A udi dealer or qualified repair facility .
They will advise you o f important meas ures,
such as cor rosion protection, maintenance
and storage procedures. Also follow the infor ­
mat ion about the battery¢
page 220.
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.
F ue l economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors:
Dri ving and the en vironm ent 195
-your personal d riving s tyle
- operati ng conditions
- technical limitat io ns
If you ant ic ipate what you need to do next and
drive econom ically , yo u can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your po cketbook.
(D Tips
The consumption estimates as published
by ENVIRO NM EN TAL PROT ECTI ON AG ENC Y
( E PA) and Transpo rt Canada may no t cor re­
spond to your actual consump tion on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con­
ditions, 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 mos t fu e l when they are ac­
ce lerating. If you anticipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next traff 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 le rat ing gently re duces fue l cons ump ­
tion, eng ine wear, and does not disturb the
environment .
Fuel consumpt ion, exhaust em iss ions an d en­
gine noise inc rease disproportionate ly at high
speeds . If you drive at approximately three
quarte rs of top speed, fuel consumption wi ll
be reduced by one ha lf. Never drive faster

ditions permit.
Reducing unnecessary idling
Even wh en your car is just idling it burns up
fuel.
,.. Shu t the engine off when you a re not dr iv ing
the vehi cle.
... Do not warm up the vehicle by letting the
engine run at idle.
It is efficien t to switch off the engine when
stopped at railroad crossings and long red
lights. Turning the engine
off for j ust 30-40
seconds saves mo re f uel than is burned by
start ing the engine again.
It takes a long time fo r the engine to wa rm up
fu lly 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 start the engine and
avoid ru nning at h igh rpms while the engine is
still warming up.
{[) Note
Do not leave engine idling unattended af­
ter starting. If warning lights s hould come
on to indicate improper operation, they
wou ld go unheeded . E xtended idling also
produces heat, which cou ld resu lt in over­
heat ing or o ther da mage to the vehicle or
o ther prope rty.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
H aving your vehicle regular ly serviced by an
author ized Audi dealer helps to ensure that it
runs properly and economically . T he condition
of yo ur vehicle not only affects its safety and
ab ility to hold its value, it also affec ts
fuel
con sumption. Check
your oil each t ime you fill your tank.
T he amou nt of oi l used is re lated to engine
lo ad a nd speed.
It is normal fo r the oil consumption of a new
engine to reach its lowest valu e after a c erta in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt io n.
This also app lies to fue l consumption and en­
gine output .
(0 Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Wa rranty
& Ma in­
tenance boo klet . Lack of proper ma inte­
nance as well as improp er use of the ve­
hicle will impair the fu nction of the
em iss io n con trol system and cou ld lead

- Do not alte r or remove any component of
t he Emis sio n Control Sys tem unless ap­
proved by the manufacturer .
- Do not alter or remove any device, such
as hea t sh ie lds, swi tches, ig nitio n w ires,
valves, which are designed to p rotec t
your vehicle's Emission Control System
and other impo rtant vehicle compo ­
nents.

198 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durability,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, always fo llow the operating
and drivi ng in str uctions provided and use
common sense.
@ Note
If you are going to tow a trai le r, you must
activate the trailer operation mode
c:::> page 198 , Operating instructions.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
b le for your veh icle and trailer and must be
mo unted secure ly on the ve hicle's chassis at a
technically sound loca tion . Use only a trailer
hi tch with a removab le ball moun t. A lways
check with the tra ile r hitch manufac turer to
make sure that you are using t he cor rect
hitch.
Do not use a bumper hit ch .
The hitch must be installed in such a way that
i t does not interfe re with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys ­
tems . From time to time, check th at a ll hitch
mo unt ing bo lts remain securely fastened.
When you are not towing a trailer, remove the
tra iler hitch ball moun t. T his prevents the
h itch from causing damage sho uld your veh i­
cle be str uck from be hind
c:::> A .
Trailer brake s
If your trailer is equipped wi th a b ra ki ng sys­
tem, c heck to be sure t hat i t conforms to all
regulations .
T he trailer hyd rauli c brake system mus t not be
direc tly connec ted to the vehicle's hydraulic
brake system .
Safety chains
Always use safety chains between your veh icle
and the tra ile r.
Trailer lights
Trai ler lights must meet all regulations. Be
sure to check w ith your Audi dealer for correct
wiring, switches and relays .
Mirrors
If you are unable to see the traffic behind you
us ing the regular o utside mirrors, then you
must install extended mirrors. It is important
that you
always have clear v is ion to the rear.
A WARNING
--
Afte r removi ng the trailer hitch, do not
stor e it in your vehicle . In case of sudden
b raking, t he hitch co uld fly forwa rd and i n­
j ur e you or your passengers.
Operating instructions
Maximum trailer weight
A tra ile r fo r your vehicle is limited to a typical
class 1 or class 2 tr ailer.
Trailer load distribution
Be sure the load in the tra ile r is held secure ly
i n place to p revent it from shift ing forward,
backward or sideways.
Ne ver allow a pa ssenger to ride in a trailer
c:::> A in Driving instructions on page 199 .
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is important that the cooling system's
performance is up to the additional load.

Make sure that the cooling system has enough
f luid .
Tire pressure
When tow ing a trai ler, inflate the t ires of your
veh icle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open) .
Inflate trailer tires to trai ler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
lights are working properly.
Safety chains Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they wi ll not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
sepa ration from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obta in the best poss ible handling of vehicle
and trai le r, p lease note the following:
.. Do not tow a loaded tra iler when your car it ­
self is not loaded .
.. Be especially carefu l when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight distribution
Tow ing a loaded trailer with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
Trailer towing 199
low speeds on ly to avoid the risk of losing
steering contro l.
A "balanced " rig is easier to operate and con­
trol. This means that the tow vehicle should
be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the c ircumstances. Whenever poss i­
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficu lt it be­
comes for the driver to control the rig. Do not
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill .
Reduce vehicle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating .
Observe speed limits. In some areas, speeds
for vehicles towing tra ilers are lower than for
regular veh icles .
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­ gine braking effect to slow the vehicle . Use of
the brakes alone ca n cause them to overheat
and fail.
Coolant tempe rature
The coo lant temperature gauge¢
page 12
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
cli nes in a low gear at high engine speeds . Re ­
duce your speed immediately if the LEDs in
the top part of the display turn on.

Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because of the additional weight and
different weight distribution. Safety, perform ­
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than normal
turn ing radius .
When passing, remember that you cannot ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
ing lanes aga in.
Avoid jerky starts, sharp turns or rapid lane
changes .
(D Tips
-Do not tow a tra iler during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load
q page 268.
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Turn the whee ls towards the curb.
.. App ly the parking brake.
.. Select the P selector lever position.
When restarting after parking:
.. Apply the foot brake .
.. Start the engine .
.. Select the D/S selector lever position.
.. Release the parking brake and s lowly pull
out and away from the wheel chocks .
.. Stop and have someone retrieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission to P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
later to move the lever out of the P posi­
tion.

206 Checking and Filling
Checking and Filling
Gasoline
Fuel supply
Applies to vehicles: with gasoline engine
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline . Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of91 AKI (95
RON) . For more information on TOP TIER De ­
tergent Gasol ine, please go to the official
website (www .toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the ins ide of the fuel filler flap. This rat­
ing may be specified as AKI or RON .
Your vehicle may also be operated using un­
leaded regular gasoline with a minimum oc ­
tane rating of 87 AKI/91 RON . However, using
87 AKI/91 RON octane fuel will slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see~
page 207.
Octane rating
Octane rating ind icates a gasoline's ability to
res ist engine damaging "knock" caused by
premature ign ition and detonation . Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane
r atings that can usually be found on the filler
pump : - Premium Grade: 91
-96 AKI
- 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 w ith octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will severely damage
your vehicle'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
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AK I or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must not contain more than 10%
ethanol.
Blend of gasoline and MTBE
-Anti-knoc k index must be 87 AK I 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 stations where the sea­ sonal adjustment is more likely to be made in
time.
Q;) 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 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
specificat ions, ask your service station or
i ts 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
lems 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 cer tain
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.
Checking and Filling 207
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www .toptiergas .com) .
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your engine of peak performance.

Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instructions see
c::> page 209.
You can find the fuel tank capacity of your ve ­
hicle in
c::> page 266.
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
c::> page 206 .
Your vehicle fuel tank has an on board refuel­
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
properly while protecting the environment,
please follow this refueling procedure careful­
ly .
A 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, full or empty, may leak and could
cause a fire in a collision . If you must

ing the use, transportation and storage of
such fuel containers . Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86) .
(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.
