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
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

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.
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 durab ility,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra
tion from the driver.
F or this reason, a lways fo llow the operating
and driving instructions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
ac tivate the trailer operation mode
c::> page 209, Operating instructions.
Technical requirements
Traile r hitch
Use a weig ht-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita
b le for your veh icle and trailer and must be
mounted securely on t he ve hicle's chassis at a
technically sound location . Use only a trail er
hi tch w ith a removab le ball moun t. A lways

A tra ile r fo r you r vehi cle is l imited to a typi cal
cla ss 1 o r class 2 tr ailer.
Trailer load distribution
Be sure the load in the tra ile r is held secure ly
in place to p revent it from shift ing fo rward,
ba ckward or sideways.
Never allow a passenger to ride in a trailer
c::> .& in Driving instructions on page 211 .
Engine cooling sy stem
Towing a t railer ma kes the engine wor k hard
er . It is impo rtant that the cooling system's
performance is up to the additional load.
•
•
Always apply brakes early. When driving
downhill, shift into a lower gear to use the en
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. The coo lant tem
perature can increase if you drive on long in
clines 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 .

A WARNING
Anyone not properly restrained in a mov
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wearing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your vehicle hand les different ly when towing
-
a trailer because of the additional weight and
d ifferent weight distribution . Safety, perform
ance and economy w ill 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 veh icle-trailer comb ination behaves and
responds .
Backing up is diff icult and requires practice .
Backing up with a tra iler genera lly requires
steer ing 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 towing 211
trailer, you wi ll need a larger than normal
turning radius.
When passing, remember that you cannot ac
ce lerate as fast as you norma lly would be
cause of the added load. Make sure you have
enough room to pass. After passing, allow
plenty of room for your trailer before chang
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(0 Tips
- Do not tow a trailer 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¢
page 285.
Parking on a slope
Do not pork 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
veh icle and the trailer wheels.
"' With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake.
.,. Select the P selector lever posit ion.
When restarting after parking:
.,. App ly the foot brake.
.,. Start the engine.
.,. Select the D/S selector lever position .
.,. Release the parking brake and slowly pull
out and away from the wheel chocks.
.,. Stop and have someone retr ieve the wheel
chocks .

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.
