heavy acceleration. This gives best fuel efficiency, with early
upshifting and delayed downshifting.
The transmission will automatically select the
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds. Upshifts are delayed to make full use
of engine power. Downshifting takes place at higher engine speeds
than in the economy programs.
The selection of the most suitable shift program is a continuous,
automatic process. The driver can a lso make the transmission
switch to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down into a lower gear ratio
and makes quick acceleration possible (to pass another vehicle) You
do not need to press the gas pedal into the kickdown range. After
the transmission has upshifted, the original program is selected
according to your driving style .
An additiona l shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients.
This prevents the transmission from shifting up and down unneces ­
sari ly on hills. The transmission will shift down to a lower gear ratio
when the driver presses the brake pedal on a downhill gradient. This
makes use of the braking effect of the engine without the need to
shift down manually .
If you are driving in hills and mountains, the transmission will
continuously adjust the gear ratio to the road grade. If you press the
brake pedal when driving downhill, the transmission will downshift
automatically . This increases the braking effect of the engine.
If the cruise control is on when you are traveling downhill, the trans­
mission will automatical ly select a lower gear ratio in order to main­
tain the set vehicle speed . This will cause the engine speed to
increase. •

When accelerating, the transmission will automatically shift into the
next higher gear before the engine reaches the maximum RPM .
When accelerating, if you apply a light throttle, the tiptronic® wil l
automatically shift into the next higher gear to save fuel. If you apply
a heavy throttle, the transmission will stay in gear engaged until
near maximum RPM are reached, or until the driver manually shifts
into a higher gear.
If you take your foot off the accelerator pedal when driving down a
steep incline, the tiptronic ® wi ll downshift from the selected gear
into the next lower gear based on road speed and engine RPM . The
automatic downshifting is interrupted as soon as you apply throttle
again .
[ i ] Tips
• When you shift into the next lower gear, the engine will down ­
shift only when there is no possibility of over-revving.
• When the kick -down comes on, the transmission will sh ift down
to a lower gear depending on vehicle and engine speeds.
• The tiptronic® is inoperative when the transmission is in the fail ­

Driving and 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 first 600 miles (1,000 kilometers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
- Speeds can gradually be increased to the maximum
permissible road or engine speed.
During and after break-in period
- Do not rev the engine up to high speeds when it is cold.
This applies whether the transmission is in N (Neutral) or
1n gear.
After the break-in period
- Do not exceed maximum engine speed under any
circumstances.
- Upshift into the next higher gear
before reaching the red
area at the end of the tachometer
scale => page 12.
Controls and equip­
ment Safety first
Vehicle operation
During the first few hours of driving, the engine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break-in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 kilometers).
0 Note
Extremely high engine speeds are automatically reduced. However,
these rpm-limits are programmed for an engine well run-in, not a
new
engine.
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .•
New tires
If your vehicle is running on new tires, drive particularly
careful for the first 350 miles (500 kilometers) after fitting.
& WARNING
New tires tend to be slippery and must also be "broken-in". Be
sure to remember this during the first 350 miles (500 kilometers).
Brake
gently. Avoid following closely behind other vehicles or
other situations that might require sudden, hard braking.

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometers) after they
are i nstalled .
New brake pads have to be "burn ished in" befo re they have opti mal
grab =>& .
During the break -in period, you s hou ld avo id putti ng severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very h igh speeds or, for example, on moun ­
t ain passes .

Catalytic converter
It is very important that your emission control sys tem
(catalytic conver ter) is functioning properly to ensure that
y o ur vehicle is running in an environmentally sound
manner.
-Always use lead-free gasoline => page 267, "Fuel supply".
-Never run the tank down a ll the way to empty.
-Never put too much motor o il in your engine => page 278,
"Add ing eng ine oil -Neve r try to push -or tow -s ta rt yo ur vehic le.
The catalytic converter is an efficient "clean-up " device built into the
exhaust system of the vehicle. The catalyt ic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
T he exc lusive use o f un leaded fue l is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate th e veh icle in ar eas wh ere the hot
ex hau st sys tem m ay come in contac t w ith dr y gra ss, bru sh , fuel
s pill or other material which can cau se a fire .
• Do not appl y additi ona l under coating or ru stpr oofing on or

0 Note
• Be aware that just one tank filling with leaded fue l wi ll already
ser iously degrade the performance of the catalyt ic converter.
• Do not exceed the correct engine oi l
level=> page 278.
• Do not drive until the fuel tank becomes comp letely empty . The
engine could misfire . Unburned fuel could also get into the exhaust
system and this could cause the catalytic conver ter to overheat .
• Do not turn off the ignition wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the cata lyt ic converter . This cou ld result
in overheating of the converter, requiring its rep lacement .
• To assure eff icient operat ion of the Em iss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance

- Lack of proper maintenance as wel l as improper use of the
vehic le wi ll impair the func tion of the emission control system
and cou ld lead to damage .
<£> For the sake of the envir onm ent
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas sme ll under some
operat ing states . Th is depends on the sulfur content of the fuel
being used. Using a different brand of fue l may he lp, or fil ling the
tank with lead -free super grade gasol ine. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
e tc., make certain that low- lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especial ly true for vehicles with low -s lung chassis (sports
chassis)* and ful ly loaded vehicles .•
Operate your vehicle economically
and minimize pollution
General
Y o ur personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, env ironmental impact, and wear on your engine,
brakes and t ires largely depend on three factors :
• your personal driving sty le
• operat ing cond it ions
• technica l limitat ions
Controls and equip­
ment Safety first Vehicle operation
If you anticipate what you need to do next and drive economica
lly,
you can easily cut your fuel consumptio n by 10 -15 percent . This
section wil l give you some tips on how you can help the environ­
ment and your pocketboo k.
[ i ] Tips
The cons umption estimates as pub lished by ENV IRO NM EN TAL
PRO TECTION AGENCY (EPA) and Transport Canada may not corre ­
spond to your actua l consumption on the road, which wi ll vary
depending upon veh icle load and speed, road and weather condi ­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they ore accelerating .
-Avoid unnecess ary accelerating and brak ing.
Vehic les use the most fue l when they are accelerating . If you ant ici ­
pate what is going to happen ne xt, you wi ll need to brake less and,
thus , acce lerate less. Let the vehicle coast whenever poss ib le -for
examp le when you see that the next traffic light is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep we ll below your car 's max imum speed.
Acce lerating gent ly reduces fue l consump tion , engine wear, and
does no t disturb the environme nt.
Fue l consumption, exhaust emissions and engine noise increase
disproportionately at h ig h speeds . If you drive at approx imate ly
three quarters of top speed, fuel consumpt ion wil l be reduced by _,,,

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle .
- Do not warm up the vehic le by letting the engine run at
id le .
It makes sense to shut off the engine in traff ic jams, when waiting
for tra ins to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emiss ions are espec ially
high when the engine is warming up . So you should drive away as
soon as you sta rt the engine and avoid running at high rpms w hile
the engine is sti ll warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended id ling also produces heat, which could
resu lt in overheating or other damage to the vehic le or other
property .•
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your ve hicle serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economical ly . The cond ition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel consumpt ion .
Check your oil ea ch time you fill your t ank .
The amount of oil used is related to engine load and speed.
I t is norma l for the oi l consumption of a new engine to reach its
lowest value after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fue l consump tion and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
t he service recom mendat io n s in your Maintenance
& Wa rranty
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impai r the function of the emission cont rol system and
cou ld lead to damage.
• Do no t alte r or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do not alte r or remove any dev ice, such as heat shields,
switches, ignition wires, valves, which are designed to protec t your
vehic le's Emission Control System and other important veh ic le
components .•
Fewer short trips
Fuel consumption will alw ays be rel atively high on short
t r ips.
- Try to avo id driving short dis ta n ces wi th a cold engine. ~

The engine and catalytic converter have to reach their optimal oper ­
at ing te mpera tur e to reduce fuel consumption and noxious emis ­
sions effective ly .
Just after starting, a cold engine in a mid -size car only achieves a
f ue l economy of 6-8 miles per ga llon (30-401/100 km). After about a
half a mile, fue l economy climbs to 12 mpg (201/100 km). After about
2.5 m iles (4 km), the engine is at its proper operat ing temperature
and fuel economy has reached a normal level. So you can see that
you should avo id short tr ips whenever poss ib le .
The outsi de te mp eratur e is also critical in this regard . Your car
consumes more fuel in the winter than in the summer. •
