Driving Notes
The forward gears are shifted up or down automatically.
Starting from stop
-Step on and hold the brake pedal.
Fig. 87 Section from
center console:
Selector lever with
release button
- Hold the release button (button in selector lever) down,
move the selector lever to the desired position, for
example D =:>
page 100, and release the button.
- Release the brake pedal and accelerate =:>& .
Stopping temporarily
Bring the vehicle to a full stop with the brake, e.g. at
traffic signals.
Do not accelerate.
Parking
-Step on and hold the brake pedal =:> & .
Apply the parking brake firmly.
- Hold the release button down, move the selector lever to
P and release the button.
Stopping on an incline
-Always hold the vehicle with the footbrake or parking
brake in order to prevent "rollback"=:>& . Do
not try to
prevent the vehicle from rolling back by rewing the
engine while it is in gear.
Starting on a hill
- Apply the hand brake firmly.
- With the engine in gear, gradually accelerate and release
the hand brake.
The engine can only be started with the selector lever in P or N
=> page 93. At low ambient temperatures (14 °F /-1 O °C), it is only
possible to start the engine with the selector lever in P.
When parking on level ground, it is sufficient to place the selector
lever in P. On a steeply sloping road , you should first apply the
parking brake firmly and then place the selector lever in P. This way,
you do not overload the pawl mechanism and it is easier to move
the selector lever out of P.
& WARNING
• Never leave your vehicle with the engine running while in gear.
If you must leave your vehicle with the engine running, set the
parking brake and engage the park lock.
• When the engine is running and the transmission is in gear (D,
S or R) or in "tiptronic" mode, it is essential that you stop the
vehicle with the footbrake. When idling, the transmission of power
does not stop completely -the vehicle "creeps".
• Do not accelerate when you change the selector lever position
with the vehicle stationary and the engine running -risk of an acci ­
dent!
• Never place the selector lever in the R or N position while the
vehicle is moving -risk of an accident!

Switching to manual
-Push the selector lever to the right from D. As the trans ­
mission has switched,
6 5 4 3 2 1 appears in the display,
with the gear that is engaged highlighted.
Upshifting
Tap the selector lever forward (in the tiptronic setting)
=> page 103, fig. 88 G).
Downshifting
- Tap the selector lever backward (in the tiptronic setting)
o.
Switching to manual can be carried out with the vehic le stationary
as well as moving .
When accelerating, the transmission shifts into the next gear in gears 1 , 2, 3, 4 and 5 shortly before the maximum permissible
engine speed is reached.
If you have selected a lower gear than the current one , the transmis­
sion will only shift down when the engine cannot be overspeeded.
If kick -down is actuated, the transmission shifts into a lower gear
independently of speed and engine rpm .•

Kick -dovvn feature
The kick-down feature allows maximum acceleration.
If you depress the accelerator pedal fully beyond the full-throttle
position, the transmission automatically downshifts one gear,
depending on vehicle speed and engine rpm. The upshift into the
next higher gear takes place as soon as the maximum specified
engine speed is reached.
& WARNING
Please note that the drive wheels can spin if the kick-down is used
on a smooth slippery road -risk of skidding! •
Applies to vehicles : withs t ro ni c®
Launch Control Program
The Launch Control Program permits maximum accelera­
tion .
In order to use Launch Control, the ASR (Anti-Slip Regula­
tion) must be disabled. When ASR is disabled, the ESP
warning/indicator light 9 in the instrument cluster illumi­
nates . So that Launch Control can be used, the engine must
be at operating temperature and the steering wheel must
not be turned .
- With the engine running, briefly press the ESP button.
The message "ASR off" appears in the instrument cluster
d isplay.
- Shift the gear lever to "S" or the tiptronic® position.
- Step on the brake pedal with your left foot and keep the
brake pedal fully depressed for at least one second.
Controls and equip ­
ment
- With your right foot, step on the accelerator to the wide­
open throttle position or Kickdown. The engine speed
settles at about 3,200 rpm.
- Take your left foot off the brake.
The S tronic® in your vehicle is electronically controlled. A special
Launch Control Program provides the best acceleration from a
standing start .
& WARNING
• Always adapt your driving to the traffic flow.
• Only use Launch Control when road and traffic conditions allow
it and other drivers will not be endangered or annoyed by your
driving and the acceleration of the vehicle.
• Make sure that ESP remains enabled. With the ESP disabled,
the vehicle could brake away, particularly on a slick and slippery road -risk of skidding!
• Once acceleration is finished, switch ASR on again by briefly
pushing the ESP button. •
Applies to vehicles: with S tronic®
Back-up program
In the event of a system malfunction, there is an back-up
program.
In the event of system malfunctions, the automatic transmission
switches to the fail- safe mode. This is signalled by one segment or
all the segments in the display illuminating or going out .
Th e effect of a system malfunction can be one of the following:
• The program shifts only into certain gears.
• Reverse gear can no longer be engaged.

Fig. 102 The vehicle
crashes into the wall.
The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
weight . Engineers call this energy "kinetic energy."
The higher the speed of the vehicle and the greater the vehicle's
weight, the more energy that has to be "absorbed" in the crash.
Vehicle speed is the most significant factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times!
Because the occupants in this vehicle are not using safety belts
~ page 126, fig . 101, they will ke ep moving at the same sp eed the
vehicle was moving just before the crash, until something stops them -here, the wall~ fig. 102 .
The same principles apply to people sitting in a vehicle that is
involved in a frontal collision . Even at city speeds of 20 to 30 mph
(30 to 50 km/h), the forces acting on the body can reach one ton
(2,000 lbs, or 1,000 kg) or more . At higher speeds , these forces are
even greater.
People who do not use safety belts are also not attached to their
vehicle. In a frontal collision they will also keep moving forward at
the speed their vehicle was travelling just before the crash. Of
course, the laws of physics don't just apply to frontal collisions, they
determine what happens in all kinds of accidents and collisions. •
Safety first
Safety belts
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves
from flying forward and being injured or killed. Always
wear your safety belts!
Fig. 103 A driver not
wearing a safety belt is
violently thrown
forward
Fig . 104 A rear
passenger not wearing
a safety belt will fly
forward and strike the
driver
Unbelted occupants are not able to resist the tremendous forces of
impact by holding tight or bracing themselves. Without the benefit
of safety restraint systems, the unrestrained occupant will slam
violently into the steering wheel , instrument panel , windshield , or
whatever else is in the way~ fig. 103 . This impact with the vehicle
interior has all th e energy they had just before the crash.
Never rely on airbags alone for protection. Even when they deploy,
airbags provide only additional protection. Airbags are not
91>
Vehicle care I I irechnical data

___ S_a_ f_ e_ t-= y_ b_e_ l_ t _s _______________________________________________ _
supposed to deploy in all kinds of accidents. Although your Audi is
equipped with airbags, all vehicle occupants, including the driver, must wear safety belts correctly in order to minimize the risk of
severe injury or death in a crash.
Remember too, that airbags will deploy only once and that your
safety belts are always there to offer protection in those accidents
in which airbags are not supposed to deploy or when they have
already deployed. Unbelted occupants can also be thrown out of the
vehicle where even more severe or fatal injuries can occur.
It is also important for the rear passengers to wear safety belts
correctly. Unbelted passengers in the rear seats endanger not only
themselves but also the driver and other passengers:::::,
page 127,
fig. 104. In a frontal collision they will be thrown forward violently,
where they can hit and injure the driver and/or front seat passenger. •
Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision. It's simply not true!
Fig . 105 Driver is prop­
er ly restrained in a
sudden braking
maneuver.
Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy
levels applied to the body in an accident, and help prevent the uncontrolled movement that
can cause serious injuries. In addition,
safety belts reduce the danger of being thrown out of the vehicle.
Safety belts attach passengers to the car and give them the benefit
of being slowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles. By "absorbing" the kinetic energy over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less likely to cause injury.
Although these examples are based on a frontal collision, safety belts can also substantially reduce the risk of injury in other kinds
of crashes. So, whether you're on a long trip or just going to the
corner store, always buckle up and make sure others do, too . Acci­
dent statistics show that vehicle occupants properly wearing safety
belts have a lower risk of being injured and a much better chance of
surviving an accident. Properly using safety belts also greatly
increases the ability of the supplemental airbags to do their job in a
collision . For this reason, wearing a safety belt is legally required in
most countries including much of the United States and Canada.
Although your Audi is equipped with airbags, you still have to wear
the safety belts provided. Front airbags, for example, are activated
only in some frontal collisions. The front airbags are not activated in
all frontal collisions, in side and rear collisions, in roll overs or in
cases where there is not enough deceleration through impact to the
front of the vehicle. The same goes for the other airbag systems in
your Audi. So, always wear your safety belt and make sure every­ body in your vehicle is properly restrained! •
Important safety instruct~ons about safety
belts
Safety belts must always be properly positioned across
the strongest bones of your body.
Always wear safety belts as illustrated and described in
this chapter. _,

Intelligent technology
Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were installed in a vehicle for the express purpose of
retrieving data after an accident or crash event w ithout the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, engine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le-related data
during norma l vehicle opera tion for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, direction,
braking as well as restraint system use and performance in the
even t of a crash or other condition . Stored data can only be read and
downloaded with special equipment.
Electronic Stabilization Program (ESP)
Genel'61
The Electronic Stability Program increases driving
sta bility.
Fig . 13 0 Cente r
cons ole with ESP
sw itch
With ESP, control over the veh icle is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
H ow ESP work s
The ESP control unit processes the following data from high-sensi ­
tive sensors: the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
actual vehicle behavior . If the two do not match, for example when

the vehicle begins to skid, ESP brakes the appropriate wheel auto­matical ly .
The vehicle is stabilized again by the forces acting on the wheel during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed .
This brake application is accompanied by noises.
ESP works in conjunction with ABS=:>
page 187. If there is ma lfunc­
tion in the ABS, ESP is also inoperative .
Activa ting
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode . With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 182, fig. 130 returns the
system to normal operation.
D eac tiva ting
ESP should norma lly be activated at all times because this ensures
optimum vehicle stability . Only in certain exceptional cases it does
make sense to deactivate Anti -Slip Regulation (ASR) or the Elec ­
tronic Stability Program !ESP) by pressing the button =:>
page 182,
fig. 130. Both deactivation stages can only be activated from normal
mode.
Dea cti vat ing ASR
Tap the switch . Deactivation is indicated by slow flashing of the ESP
lamp in the instrument c luster. In certain situations (e.g. driving
with snow chains, in deep snow or on loose ground, or when rocking the car free), it may be necessary to deactivate ASR. Deacti ­
vation is effective only up to a speed of about 45 mph (70 km/h). At higher speeds, ASR is switched on again automatical ly in front ­
whee l drive vehicles, deactivation is possible only up to about 30
mph (50 km/h). With all -whee l drive vehicles, ASR is active above
Controls and equip­
ment Safety first Vehicle operation
In
te llig ent tec hn olo gy
about 45 mph (70 km/h) and deactivated automatical ly below this
speed.
D eac tiva tin g ES P/ASR
Press the button for more than 3 seconds . Deactivation is indicated
by the ESP lamp in the instrument c luster staying on permanently .
This deactivates the E lectronic Stabi lity Program (ESP) in addition to
ASR . No Electronic Stability System operation and no Anti-Slip
Regu lation is availab le across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stab le vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traff ic situation permit .

Electronic differential lock (EOL)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The electronic differential lock (EDU helps the car to start moving,
accelerate and climb a gradient on surfaces providing poor or
almost no grip. Without EDL, this would be difficult, if not impos ­
sible.
How the system works
Th e EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=> page 187. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground on
one side), the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/hl. Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate . If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily . The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning . This is
indicated by the ABS warning light=> page 20. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler ­
ates , the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface .
How the system works
ASR performs automatically, i.e. without the driver's intervention .
With the aid of the ABS sensors => page
187, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface . The system is active across the entire
speed range.
The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action .
