110 Automatic Tran sm iss ion
multitronic transmission : Your vehicle is
equipped with
hill hold assist allowing you to
start while on an incline. The system is acti­
vated when the brake pedal is pressed down
and held
f o r a few s econds . The brake pres­
sure will hold for
a moment after the brake
pedal loosens to prevent the veh icle from roll­
ing backwards whi le starting up .
A WARNING
- The veh icle can also roll when the engine
is stopped.
- Unintended veh icle movement can cause
serious injury .
- Never leave your vehicle with the eng ine
running wh ile in gea r. If you must leave
yo ur 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 whee ls
when the engine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever pos ition
wh ile the vehicle is stat io nary and the
engine is running .
- Never shift into R or P wh ile driving .
- Before driv ing down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when dr iving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces b raking performance, inc reases
braking distance or causes comp lete fail­
ure of the brake system.
- T o prevent the veh icle from rolling back
when stoppi ng on incl ines, always hold it
in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipping clutch. The clutch opens auto ­
matically when it becomes too hot from the overload. An indicato
r lamp
ml illu­
minates and a driver message appears
¢ page 112 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving posit io n engaged when
checking under the hood . Make sure the
selector lever has securely engaged and is locked in P w it h the park ing brake set
¢ page 222 . Otherwise, any increase in
eng ine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied .
(D Note
-S tronic- and tiptronic transmission :
When stopping on an incl ine , do not try
t o hold the vehicle in place by pressing
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.
- S tronic- and tiptronic transmission : A l­
lowing the vehicle to ro ll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not l ubricated unde r those cir­
cumstances.
{!) Tips
For safety reasons, the parking brake is re­
l eased automatically only when the d riv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent contro l is activated when these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is su itable fo r the incline. H ill de­
scent contro l tries to ma inta in the speed ach­
ieved at the time o f braking, within phys ica l
and technical limitations. If may sti ll be nec -
essary to adj ust the speed with the brakes . ..,..

Hill descent control switches off once the de­
cline levels out or you press the accelerator pedal.
On vehicles with the cruise control system*
¢ page 82, hill descent control is also activat­
ed when the speed is set.
A WARNING
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the
brakes .

when the engine speed is with in the permit­
ted range.
@ Tips
- When 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 fai l-safe mode.

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 147 Unbelted occupants in a ve hicle heading for a
wall
Fig. 148 The vehicle cras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
ergy."
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
SO km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not
using safety belts¢
fig. 147, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them - here, the wall ¢
fig. 148.
Safety belts 13 7
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 forces are even
higher.
People who do not use safety belts are also
not attached to their vehicle . In a frontal colli­
sion 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 app ly to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions.
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!
Fig. 149 A driver not wea ring a safety be lt is vio lently
thrown forward
Fig. 150 A rear passenger not wearing a safety belt

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 what­
ever else is in the way
c::> fig. 149. This impact
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. 150. 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. 151 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 193
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 the 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 includes and/or works together with the
anti-lock brake system (ABS), brake ass ist sys­
tem, ant i-slip regu lation (ASR), electron ic dif­
ferential lock (EDL), dynam ic steer ing* and
El ectronic interax le differentia l lock* /selective
whee l to rque control*. ESC is switched on a ll
the time. In ce rtain sit uat io ns when yo u need
less traction, you can sw itch off ASR by press­
ing the b utton
[fil ¢ page 195, fig. 178. Be
s u re to switch ASR on again when you no lon­
ger need less traction .
Anti-lock braking system (ABS )
ABS prevents the whee ls from locki ng up
when b raking. The vehicle can st ill be stee red
even during 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 indicates that
the system is helping you to brake the vehicle.
Brake a ssis t sy ste m
The brake ass ist system can decrease braking
distance . It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the situation is over. In .,,.
