with the footbrake . The parking brake elimi­
nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from unintentiona lly ro ll­
ing back. The braking force of the parking
brake is not released until sufficient driving
force has been bu ilt up at the wheels.
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch(®) pulled and depress the
acce lerator. The parking brake stays applied
and prevents the vehicle from ro lling back­
ward.
.. You can release the switch (®) once you are
sure that you are develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
Depending on the weight of the r ig (vehicle
and tra iler) and the severity of the incl ine, you
may roll bac kwards as you sta rt. You can pre­
vent roll ing backwards by holding the parking
b rake switch (®) p ulled out and acce lerat ing -
just as you would when starting on a hill with a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks .
.. In an emergency, pull the switch(®) and
contin ue to p ull it t o slow your vehicle down
with the parking brake.
.. As soon as you release the switch (®) or ac­
ce lerate, the braking process stops.
If you pull the switch(®) and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy bra king f unct ion is initiated. The vehicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is simila r to making an emergency stop
c> .&. .
In order not to act ivate the emergency brak­
ing by mistake, an audib le warning tone (buz­
zer) sounds when the switch(®) is pulled. As
soon as the sw itch (®) is re leased, or the accel­
erato r pedal is depressed, eme rgency braking
stops .
.&, WARNING
E mergency braking should only be used in
a n emergen cy, when t he norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the par king brake to perform emer ­
gency b raking will s low your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and its associated compo­ nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake application can cause the v ehi­
cle to s kid or the rear end to break away -
r isking an a cci den t.
Start-Stop-System
Description
Appl ies to vehicles : wit h Start-Stop-System
The Start-Stop-System can help increase fuel
economy and reduce CO2 emissions .
In the Start -Stop -mode, the engine shuts off
automat ica lly when the veh icle is stopped,
such as at a traffic light. The ignition remains
switched on during this stop phase. The en­
gine wi ll be automat ica lly restarted when
needed .
The last Start-Stop-System setting (on/off us­
ing the button
l 0a• I) will be restored when the
ignition is turned on. The LED in the !09 ~1 but­
ton turns on when the Start-Stop-System is swit ched off manually.

116 Automatic Transmission
Automatic
Transmission
tiptronic (8-speed
transmission)
Introduction
Your vehicle is equipped with an electronically controlled 8-speed automatic transmission .
Upshifting and downshifting occurs automati­
cally and is controlled electronically. The driv­
ing style continuously influences the selection
of the driving program .
When a
moderate driving style is used, the
transmission selects the most economical
driving mode. It will then change up early and
delay the downsh ifts to give better fuel econ­
omy .
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling at the maximum speed.
If desired, the driver can also select the gears
manually (ti ptronic mode)¢ page 119 .

.. To engage the nearest selector lever posi­
tion, move the selector lever forward/back
until you fee l the first pressure point. The
selector lever will return to its original posi­
tion .
.. To skip over one (or two) selector lever posi­
tions, move the selector lever past the first
(and second) pressure point into the desired
position. The selector lever will return to its
original position.
For example, to move directly from the D se­
lector lever position to P when stopping the
vehicle, you can shift past the N and R selector lever positions. .,,_

208 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 222,
Fuel supply .
.. Never run the tank down all the way to emp-
ty .
.. Never put too much motor oil in your engine
¢ page 23 7, 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 already seriously de­
grade the performance of the cata lytic
conve rter. -
Do not exceed the correct engine oil level
i=>page 237.
-Do not drive until the fue l tank becomes
completely empty . The engine co uld 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 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 .
Using 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
ter 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 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 243.
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 209
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 88.
(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 econom ically, you can easily cut your
fuel consumpt ion by 10-15 percent . Th is sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook. •
•

210 Driving and environment
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, trip 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 mo st 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 possible -for example 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 well below your car's maximum
speed .
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment .
Fuel consumption, exhaust emissions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions 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 vehicle by letting the
engine run at idle.
The idling phase is automatically reduced for
vehicles with the Start/Stop system. It is effi­
cient to switch off the engine in vehicles with­
out the Start-Stop-System when stopped at
railroad crossings and long red lights. Turning
the engine off for jus t 30-40 seconds saves
more fuel than is burned by starting the en-
. . gme again.
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up . So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
W Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could result in over­
heating or other damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
• Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop­
erly and economically. The condition of your
vehicle not only affects its safety and ability to
hold its value, it also affects
fuel consump­
tion.
Check your oil each time you
fill your tank.
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven . ..,.

You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly
assess o il consumption.
This also applies to fuel consumption and en­
gine output.
(D Note
- Have yo ur vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the funct ion of the
emission control system and could lead
to damage .
- Do not alter or remove any component of
the Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any dev ice, such
as heat shields, switches, ignition wires,
valves, wh ich are designed to protect
your vehicle's Emission Control System
and other important veh icle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avo id driving short distances with a
cold engine .
The engine and catalyt ic converter have to
reach their optimal
operating temperature to
reduce fuel consumption and noxious emis­
sions effect ively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6 -8 miles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km). Afte r abo ut
2.5 m iles (4 km),
the eng ine is at its proper operating tempera­
ture and fue l economy has reached a normal
l eve l. So you can see that you should avoid
short trips whenever possible.
Driving and environment 211
The outside temperature is also critical in this
regard . Your car consumes more fue l in the
winter than in the summer.
