Catalytic converter
Appl ies to vehicles: with gasoline e ngin e
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 gasoline¢ page 215,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 229, Adding engine oil .. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff ic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalyti c converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere.
The exclus ive use of unleaded fuel is cr itically
important for the l ife of the cata lytic convert­
e r and proper functioning of the engine.
A WARNING
T he temperature of the exhaust system is
high, both when driving and after stopping
the engine .
- 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,
fuel spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
@) Note
- Be aware that just one tank f illing with
leaded fuel will al ready seriously de­
grade the perfo rmance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
¢page 229.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld m is­
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 mov ing .
- Do not continue to ope rate your vehicle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result in overheating of the con­
verter, requir ing its replacement .
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle maintained p roperly
and in accordance w ith the service rec­
ommendations in your Warranty & Maintenance book let.
- Lack of prope r maintenance as we ll as
improper use of the vehicle wi ll impair
the function of the em ission contro l
system and could lead to damage.
@) For the sa ke of the en vironment
Even when the Emission Control System is
ope rat ing properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operat ing states. This depends on
the sulfur content of the fuel being used .
Usi ng a different brand of fuel may help,
or f illing the tank with lead-free super
grade gasoline.
Diesel particulate filter
Applies to vehicles: with diese l eng ine
The diesel part icu late filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r cleans itself automat ica lly unde r no rma l
dr iv ing cond itions . If the filte r cannot clean it­
self (for example, because you are on ly driving
short distances), the filter becomes clogged
with soot and the
II symbol for the diesel
particulate filter ill uminates ¢
page 22. ..,.

A WARNING ,~
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel par­
t icu late filter cou ld start a fire .
- Do not apply an underbody protectant in the exhaust system area or a fire could sta rt.
Avoid damaging the
vehicle
When you are driving on poor roads, o r over
curbs, steep ramps, etc., make ce rtain that
l ow -lying parts such as spoi lers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low ­
slung chassis (sports chassis)* and f ully load ­
ed veh icles.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iv ing t hrough water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the veh icle body.
- Do not drive faster than wa lking speed.
A WARNING
After driving through water, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake roto rs and pads. Dry
the brakes fi rst by brak ing carefully to re­
sto re the full b raking effect.
- Vehicle components such as the eng ine,
transmission, suspension or e lectr ical
system can be severe ly damaged by driv­
i ng th rough water.
- Always switch off the Start-Stop-System
when driving through water
r::;> pag e 79.
-
Dri vin g and en vironm ent 203
(D Tips
-Check t he dept h of the water before d riv­
ing through it .
- Do not stop the vehicle, drive in reverse
or switch the e ngine off w hen driving
thro ugh water.
- Keep i n mind t hat oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi ­
cle to drive through safely.
- Avo id driving through salt water because
it can cause corros ion.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of t i me, contact an
Audi or other spec ia lized dealer. They can ad­
vise you on necessary precautions e.g . corro­
s io n prevention, maintenance and sto rage .
Pay attent io n to additional info rmation con­
ce rning the bat tery. Refe r to ¢

Operate your vehicle
economically and
minimize pollution
General
Your per sonal style of driving will de termine
the economy of your vehicle, as well as ex ­
haust and noise levels .
Fuel economy, environme nta l impact, and
wear on your eng ine, brakes and tires la rgely
depe nd on three fac to rs:
- your personal d riving style
- operati ng conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economica lly, yo u can easily cut yo ur
f uel 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 pocketbook. •

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine id le unnecessari­
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Your Diesel engine has been specifically
designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasol ine. Th e
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
Fuel supply and filling your fuel tank 217
cause expensive engine repai rs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel should get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not
allow Diesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.
Fuel tank
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
¢ page 220.
You can find the fuel tank capacity of your ve­
hicle in
¢ page 281.
T he labe l on the inside of the fuel fi ller flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 215.
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 refue l your vehicle. In order to fi ll the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A WARNING
Under normal operating conditions, never
carry addit ional fuel conta iners 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
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the
