Catalytic converter
Applies 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 gasoline c::> page 218,
Fuel supply .
... Never run the tank down all the way to emp­
ty .
... Never put too much motor oil in your engine
c::> page 232, Adding engine oil .,. Never try to push-or tow-start your veh icle.
The catalytic converter is an eff icient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic 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 cr it ically
i mportant for the life of the cata lytic convert­
e r and proper functioning of the engine.
& WARNING ,~
T he 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 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
manifold, exhaust p ipes, catalytic con­
verter or heat shields . During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
(D Note
- Be aware that just one tank f illing with
leaded fuel will already seriously de-
grade the performance of the catalytic
conve rter.
Dri vin g and en vironm ent 205
-Do not exceed the correct engine oil level
c::>page 232.
-Do not drive until the fue l tank becomes
completely empty. The engine cou ld 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 mov ing .
- Do not continue to operate your veh icle
under these conditions, as otherwise fuel
can reach the catalyt ic converter. Th is
cou ld result i n overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have you r vehicle main tained properly
and in accordance w ith the se rv ice rec­
ommendations in your Warranty & Maintenance book let.
- Lack of proper maintenance as we ll as
improper use of t he vehicle wi ll impair
the function of the emission cont ro l
system and could lead to damage.
@) For the sake of the env ironment
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 .
Using a different brand of fuel may help,
or filling the tank with lead-free s uper
g rade gasoline.
Diesel particulate filter
App lies to vehicles: wit h diese l eng ine
The diesel part iculate filter filters nearly all of
the soot pa rticles out of the exhaust . T he fil­
te r clea ns itself automat ica lly unde r no rma l
driv ing cond itions. If the filter cannot clean it ­
self (for example, because you are on ly driving
sho rt distances), the filter becomes clogged
with soot and the
Ill symbo l for the diesel
particulate filter i lluminates

206 Driving and en vir onm ent
8_ 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 could start a fire .
- Do not apply an underbody protectant in
the exhaust system area or a fire could start.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especia lly true for vehicles with low­
slung chassis (sports chassis)* and fully load­
ed vehicles.
Driving through water
on roads
Note the following to avoid vehicle damage
when dr iving 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.
8_ WARNING
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes f irst by brak ing carefully to re­
sto re the full braking effect.
(D Note
- Vehicle components such as the engine,
transmission, suspension or electrical
system can be severely damaged by driv­
ing through water.
- Always switch off the Start-Stop-System
when driving through water~
page 81.
-
(D Tips
-Check the depth of the water before d riv­
ing through it .
- 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 driving through salt water because
it can cause corrosion.
Shutting down vehicle
If you would like your vehicle to remain inop­
erative for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance and storage .
Pay attention to additional information con­
cern ing the battery. Refer to
~ page 238.
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, env ironmental impact, and
wear on your eng ine , brakes and tires largely
depend on three factors:
- your personal driving 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 percent . This sec­
tion will give you some tips on how you can
help the environment and your pocketbook.

220 Fuel supply and filling your fuel tank
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 fue l 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 starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle 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 ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D 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 gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld 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 D iesel 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 shou ld fail, you
can still open the flap manua lly -for detailed
instructions see
¢ page 223.
You can find the fuel tank capacity of your ve­
hicle in
¢ page 283.
The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 218.
Your vehicle fuel tank has an on board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow 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 conta iners 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 blower, 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 ..,.

current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine).
C hanging the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilomete rs) and
time intervals specified in your vehicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs .
Changing the oil at the recommended inter­
vals is so very important because the lubricat­
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author­
ized Audi Service Advisor .
Under some circumstances the engine oil
should even be changed more frequently .
Change oil more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
ditions, or when you use your vehicle where
temperatures stay below freezing point for long periods.
Detergent addit ives in the oil will make fresh
oil look dark after the eng ine has been run­
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Damage or malfunctions due to lack of
maintenance
It is essential that you change your oil at the
recommended intervals using only engine oil
that complies with Audi oil standard
VW 502 00 (vehicles with gasoline engine) or
VW 507 00 (vehicles with diesel engine). Your
Limited New Vehicle Warranty does not cover
damage or malfunctions due to failure to fol­
low recommended maintenance and use re­
quirements as set forth in the Audi Owner's
Manual and Warranty
& Maintenance booklet.
Your dealer will have to deny warranty cover­
age unless you present to the dealer proof in
Checking and filling 231
the form of Service or Repair Orders that all
scheduled maintenance was performed in a
timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cooling of internal engine components, all in­
ternal combustion engines consume a certain
amount of oil. Oil consumption varies from engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see ¢
page 204) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil , the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary .
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­
el, see
Note .
If the yellow engine oil level warning symbol
in the instrument cluster
II! lights up, you
should check the oil level as soon as possible
¢
page 232. Top off the oil at your earliest
convenience
9 page 232.

Before you check anything in the engine
compartment, always read and heed all
