you can operate equ ipment such as garage
doors, property gates and house lights from inside your vehicle .
Using the Homelink universal remote control,
you can replace up to three separate hand ­
held transmitters for equipment on your
property with just one universal remote con­
trol. Most of these transmitters a re used to
operate ga rage doors and property gates. The
individual transmitters are programmed at
the front bumper. That is where the control
module is located.
The transmitters must be programmed first in
order to operate systems using the Homelink
universal remote control.
A WARNING , .,.

206 Driving and en vir onm ent
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 i=> page 220,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 234, 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
i=>page 234.
-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
Cl symbol for the diese l
particulate filter i lluminates
i=> page 21. ..,.

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 start .
Shutting down vehicle
If you would like your veh icle to remain inop ­
erat ive for a longer period of time, contact an
Aud i or other specia lized dealer. They can ad­
vise you on necessary precautions e.g . corro­
sion prevention, ma intenance and storage.
Pay attention to additiona l information con­
cerning the battery. Refer to~
page 240.
Avoid damaging the
vehicle
When you a re 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 especially 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 driving through 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, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
-
Drivin g and environment 207
the brakes first by braking carefully to re­
store 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 87.
(D Tips
-Check the depth of the water before driv­
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.
Operate your vehicle
economically and minimize pollution
General
Your personal style of driving will determine
t he economy of your vehicle , as well as ex­
haus t and noise levels.
Fuel economy, environmental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitations
If you ant icipate what you need to do next and
drive economically, you 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 pocketbook. •
•

208 Driving and en vir onm ent
The consumption estimates as published
by ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi ­
cle load and speed, road and weather con­
ditions, tr ip length, etc .
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
• Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are ac­
celerating . If you anticipate what is going to
happen next, you will need to brake less and,
thus , accelerate less. Let the vehicle coast
whenever poss ible -for example when you see
that the next traffic l ight is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
• Try and keep well below your car's max imum
speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
g ine noise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Neve r dr ive faste r
than the posted speed limit and wea ther con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
• Shut the engine off when you are not dr iv ing
the vehicle. •
Do not warm up the vehicle by letting the
engine run at id le .
T he id ling phase is automatically red uced for
vehicles with the Start -Stop -System*. It is ef ­
ficient to switch off the engine in vehicles
without the Start -Stop-System when stopped
at rai lroad crossings and long red lights . Turn­
ing the engine off for just 30-40 seconds
saves more fuel than is burned by starting the engine aga in .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are espec ially high
when the eng ine is warm ing up . So you should
drive away as soon as you start the engine and
avo id running at high rpms while the engine is
still warming up.
W Note
Do not leave engine idling unattended af­
ter start ing . If wa rning lights should come
on to indicate improper operation, they
wo uld go unheeded. Ex tended idling also
produces heat, wh ich could result in ove r­
heating or other damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
• Have your veh icle serviced at reg ular in ter -
vals .
By having your ve hicle regu la rly se rviced by an
Audi dealer he lps to ensu re that it runs p rop ­
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel con sump­
tion .
Ch eck your oil e ach time you
fill y our tank.
The amount of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven . ..,.

212 Trailertowing
drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icu larly
when going downhill.
Reduce vehicle speed
immedi atel y if the trail ­
er shows the slightest sign of swaying .
Do not
tr y to stop th e sway ing by acceler ating .
Observe speed limi ts. In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
A lways apply brakes early. When driv ing
downhill, shift into a lower gear to use the en­
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant t emperature
The coolant temperature gauge¢ page 10
must be observed carefully. The coolant tem­
perat ure can increase if you drive on long in ­
clines in a low gear at high engine speeds. Re­
duce your speed immediate ly if the L EDs in
the top part of the display turn on.
F or more in formation about indicator lights,

A WARNING
Anyone not properly restrained in a mov­
ing veh icle is at a much greater risk in an
accident . Never let anyone ride in your car
who is not properly wear ing 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 addit ional 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 ng.
Before you actually tow your trailer, practice
turning, stopp ing and back ing 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 diffi cult and requ ires practice .
Backing up with a trailer gene rally req uires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater d ista nce between you r ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning rad ius.
When passing, remember that you cannot ac ­
ce lerate as fast as you norma lly would be­
ca use of the added load. Make sure yo u have
enough room to pass. After passing, allow
plenty of room for your trailer be fore chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D 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 290.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not b e avoided, do so only after doing th e fol­
lowing:
When par king:
.,. App ly the foot brake.
.,. Have someone p lace chocks under both the
vehicle and the tra iler wheels .
.,. With chocks in place, slowly release the
brakes unt il the wheel chocks absorb the
load .
.,. Turn the whee ls towards the curb .
.,. Apply the parking brake .
.,. Select the P se lector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
