A time delay element prevents the selector
lever from locking when it is moved through
the N position (going from R to 0/5). The lock­
ing element will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
prox imately 2 second, without the brake ped ­
al being pressed.
Release button
The release button on the selector lever pre­
vents the lever from being accidenta lly shifted
into certain positions. Depending on the direc­
tion of the shift, the selector lever locks at d if­
ferent positions . The positions a re highlighted
in the illustration

On slopes, activate the parking brake first and
then move the selector lever to the P position .
This prevents too much stress from being
placed on the locking mechanism .
A WARNING
-The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause
. . . serious mJury. Iii>

112 Automatic Tran sm iss ion
-Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, act ivate the park ing brake and move the
selector lever to P.
- Power is st ill transmitted to the wheels
when the eng ine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is runn ing and the selecto r
lever is in D/S or R or "tiptronic" mode is
selected .
- Do not press the accelera tor pedal when
changing the selector lever pos ition
whi le the vehicle is stationary and the
engine is running.
- Never shift into
R or P whi le driving.
- Before driv ing down a steep slope , re-
duce you r speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when dr iving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces braking per formance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, always hold it in place with the brake peda l or parking
brake .
- Never hold the veh icle on an incline with
a slipping clutch . The clutch opens auto ­
matically when it becomes too hot from
the overload . An indicator lamp@] illu­
minates and a dr iver message appears
9 page 114 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driv ing pos ition eng aged when
check ing under the hood. Make sure the
selector lever has secure ly engaged and
is locked in P with the parking brake set
9 page 225. Otherwise, any increase in
engine speed may set the vehicle in mo­
t io n, even with the park ing brake ap ­
plied .
(D Note
-When stopping on an incline, do not try
to hold the vehicle in place by press ing
the acce lerator pedal while a driving gear
is se lected. This can cause the transmis­
sion to overheat and can damage it . Acti ­
vate the parking brake or press the brake
peda l to prevent the vehicle from roll ing .
- Allowing the vehicle to roll when the en ­
gine is stopped and the selecto r lever is
in N will damage the transmission be­
cau se it is not l ubricated unde r th ose cir­
c umstances.
(D Tips
Fo r safety reasons, the pa rking brake is re­
l eased automatically o nly when t he d riv­
er's safety belt is eng aged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent cont rol is activated when these­
lector lever is in D/S and yo u press the brake
peda l. The transmission automa tical ly selects
a gear tha t is suitable fo r the incline. H ill de ­
scent cont ro l tries to ma inta in the speed ach ­
ieved at the time of braking, within physica l
and tec hnical lim itations. If may sti ll be nec­
essary to ad just the speed with the brakes.
Hill descent cont ro l sw itches off once the de ­
cline leve ls o ut or yo u press the acce lerator
pedal.
On vehicles with the cru ise cont ro l system *
9 page 84 , hill descent control is also activa t­
ed when the speed is set.
A WARNING ,____ -
Hill descent control cannot overcome
physica l lim itations, so it may not be ab le
to maintain a constant speed under all
conditions . A lways be ready to apply the
brakes .

The transmiss ion only allows manual shifting
when the engine speed is within the permit­
ted range.
(D Tips
- Whe n you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev­
ving the engine.
- When the kick-down comes on, the
transmission will shift down to a lower
gear, depending on vehicle and engine
speeds .
- Tiptronic is inoperative when the trans­
mission is in the fail-safe mode.
Kick -down
Kick -down enables maximum acceleration .
When you depress the accelerator peda l be­
yond the resistance point, the automat ic
transmission downshifts into a lower gear, de­
pending on vehicle speed and engine speed .
The upshift into the next higher gear takes
place once the max imum specified engine
speed is reached .
A WARNING
Please note that the drive wheels can spin
if kick-down is used o n a smooth slippery
road - the re is a risk of skidd ing.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 151 Unbe lted occupants in a vehicle heading for a
wall
Fig. 152 The vehicle crashes into the wall
The physical principles are simple. Both the
veh icle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
e rgy."
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 ene rgy increases 4 times!
Because the passengers of th is veh icle are not
using safety belts
c:::;, fig. 151, they will keep
mov ing at the same speed the vehicle was
mov ing just befo re the crash, unt il something
stops them - here, the wall ¢
fig. 152.
Safety belts 139
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 greater speeds, these fo rces are even
highe r.
Peop le who do not use safety belts are also
not attached to their vehicle . In a frontal colli­
s ion they will also keep moving forward at the
speed their veh icle was travel ling just before
the crash . Of co urse, the laws of physics don't
just app ly to frontal collisions, they determine
what happens i n all k inds of a cc ident s and col­
li s ions.
What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

occupant will slam violently into the steering
wheel, instrument panel, windshield, or what­
ever else is in the way
c::> fig. 153. This imp act
with the vehicle interior has all the energy
t hey had just before the crash.
Never rely on a irbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­
posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver , must
wear safety belts correctly in order to mini­
mize 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 vehi­
cle where even more severe or fatal injuries
can occur.
It is also important for the rear passengers to
wear safety belts correctly. Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and othe r passen­
gers ~
fig. 154. In a frontal collision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger .
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. 155 Driver is co rr ect ly re strain ed in a sudd en brak­
ing maneuve r
Safety belts used properly can make a big dif­
ference. 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 tha t 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 ti me, the safety belts make the
forces on the body more "tolerable" and less
likely to cause injury.
Although these examples are based on a fron­
tal collision, safety belts can also substantial­
ly reduce the r isk 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. Accident sta­
tistics 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 supplemen­
tal airbags to do their job in a collision . For
this reason, wearing a safety belt is legally re­
quired 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 provid­
ed. Front airbags , for example, are activated
only in some frontal collisions. The front air­
bags are not activated in all frontal collisions,
in side and rear collisions, in roll overs or in
cases where there is no t enough decelera tion
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 everybody in your vehicle is
properly restrained!

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E ve nt Dat a Recorder
This vehicle is equipped with an Event Data
Recorder (EDR) . The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an airbag deployment or h itting a road obstacle, data that will ass ist in
understand ing how a veh icle's systems per­
formed. The EDR is designed to record data
re lated to vehicle dynamics and safety sys­
tems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:
- How various systems in you r vehicle were
operating;
- Whether or not the d river a nd passenger
safety belts were buckled/fastened;
- How far ( if at all) the dr iver was dep ress ing
the accelerator and/or brake peda l; and,
- How fast the ve hicle was traveling.
These data can help provide a better under­
stand ing of the c ircumstances in which crash­
es and injuries occur . NOTE : EDR data a re re­
corded by your veh icle only if a non-trivial
crash sit uat ion occ urs; no data are recorded by
the EDR under normal driving cond itions and
no personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, co uld
comb ine the EDR data with the type of per­
sonally identify ing data routinely acquired
during a crash invest igation .
To read data recorded by an EDR, special
equ ipment is required, and access to the veh i­
cle or the EDR is needed. In add ition to the ve­
h icle manufacturer, other parties, such as law
e nfo rcement, that have the special equip­
ment, can read the information if they have
access to the ve hicl e or the EDR. Some state
laws restrict the retrieval o r down­
loading of data stored by ED Rs insta lled in a
vehicle for the express purpose of retrieving data after an accident or crash event w ithout
the owner's consent .
Audi will not access the EDR and/or simi lar
data or g ive it to others -
- un less the vehi cle owner (or lessee if the ve ­
hicle has been leased) agrees; or
- upon the officia l request by the police ; or
- upon the o rder of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the ju­
dicia l discovery p rocess.
- Aud i may also use the data for research
about vehicle ope rat ion and safety perform­
ance or provide the da ta to a third party fo r
research purposes without iden tif ying the
specif ic vehicle or in formation about the
identity of its owner or lessee and only after
the recorded vehicle data has been ac­
cessed .
Vehicle control modul es
Your vehicle is also equ ipped with a n umber of
electron ic control modules for various vehicle
systems, such as engine management, emis­
sion contro l, airbags, and safety belts.
T hese electronic con trol mod ules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic
and repair purposes. The recording capability
of these modu les is limited to data (no sound
is recorded). Only a small amount of data is
actually recorded over a very lim ited period of
t ime, or stored when a system fault is detect­
ed by a contro l modu le. Some of the data
stored may re late to vehicle speed, direction,
o r braking, as well as restraint system use and
performance in the event of a crash. Stored
data can also only be read and dow nloaded
with special eq uipment that is directly con-
nected to the vehicle. .,..

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw)
out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
m in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 195
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switched on all the time. In certain sit­
uat ions when you need less traction, you can
switch off ASR by pressing the butto n
[ill
~ page 197, fig. 182. Be su re to switch ASR
o n again when you no longer need less trac­
tion.
The following systems are integrated in the
ESC:
Anti-lock bra king sy stem (ABS )
ABS prevents the whee ls from locking up
when brak ing. T he vehicle can st ill be steered
even dur ing hard braking. App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal ind icates that
the system is helping you to brake the veh icle .
Brake assi st system
The brake ass ist system can decrease braking
distance. It increases brak ing power when the
drive r presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the s ituation is over. In
vehicles wi th adap tive c rui se control*, the
brake assis t system is more sensitive if the
