_& WARNING
-Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles .
- For reasons of safety, cru ise control
should not be used in the city, in stop­
a nd-go traffic, on twisting roads and
when road cond itions are poor (such as
ice, fog , gravel, heavy rain and hydro­
p lan ing) -risk of accident .
- Turn
off the cruise control temporar ily
when enter ing turn la nes, highway exit
lanes or in construction zones .
- Please no te that inadverten tly "resting"
your foot on the accelerator pedal causes
the cruise contro l not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise contro l functions re­
main active as long as the indicator l igh t

@ Tips
- Veh icles with ma nual transmiss ion: You
can attain the set speed only if the gear
that is currently engaged will a llow it, or
if it does not tax the engine a nd allows i t
t o r un smoothly. Therefore shift in to a
higher or lower gear in a time ly manner.

Introduction
Applies to vehicles: with multitronic/S tronic/tiptronic
The automatic transmission is controlled elec ­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected .
When a
moderate driving style is used, the
transmission selects the most economical
driving mode. It will then change up early and
delay the downshifts 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
t ion, frequent changes in speed and trave ling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ~ page 91.
Various automatic transmissions may be in­
stalled, depending on the model:
multitronic transmission
The multitronic transmission is a continuously
variable transmission. Power is transferred us­
ing a multidisk clutch. In contrast to conven­
tional automatic transmissions using shifting
operations, the transmission ratio in the con­
tinuously variable transmission is changed
continuously . This optimizes the comfort level
and conserves fuel.
S tronic transmission
The S tronic is a dual-clutch transmission .
Power is transferred using two clutches that
work independently from one another_ They
replace the torque converter used in conven­
tiona l automatic transmissions and allow the ..,_

Audi adaptive cruise control and braking guard 99
Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle . This he lps to make driv­
ing more comfortable on long highway
stretches.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers
c::;, page 1 OS.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them properly at all times.
General information
General information
Applies to vehicles: with Audi adaptive cruise control
Fig. 110 Front of the vehicle: Position of radar sensor
The area that contains the radar sensor
c::;, fig. 110 must never be covered by stickers
or other objects or obstructed with dirt, in­
sects, snow or ice that will interfere with the
adaptive cruise control system and braking
guard. For information on cleaning, refer to
c::;, page 204. The same applies for any modifi­
cations made in the front area . The
function of the adaptive cruise control
system and braking guard is limited under
some cond itions:
- Objects can only be detected when they are
within sensor range
.:!>page 101 , fig. 113.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Some kinds of vehicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves
c::;, page 100.
-Stationary objects c::;, page 100.
A WARNING
-Always pay attention to traffic when adap-
tive cruise control is switched on and brak­ ing guard is active. As the dr iver, you are
still respons ible for start ing and for main­
tain ing speed and distance to other ob­
jects. Braking guard is used to assist you.
The driver must always take action to avoid
a collision. The driver is always responsible
for braking at the correct time.
- Improper use of adaptive cruise con trol
can cause collisions, other accidents and
serious personal injury .
- Never let the comfort and convenience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic conditions and the
need to remain in fullcontrolofyourve­
hicle at all times,
- Always remember that the adaptive
cru ise contro l and braking guard have
limits -they will not slow the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
moving, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle.
If registered by the radar sensor, vehicles
or obstacles that are not moving can
trigger a collision warning and if .,.

100 Audi adaptive cruise control and braking guard
confirmed by the video camera, an acute
collision warning.
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing). Using the system under
these conditions could result in a colli­
sion.
- Switch adaptive cruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac­
celerating to the set speed when in these
situations.
- Th e adaptive cruise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cr uise control system and
braking guard do not react to people, an­
ima ls, objects crossing the road or on­
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
{[) Note
The sensor can be d isp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and b
raking guard.
Have your authorized Audi dea ler or au­
thorized Audi Service Facility check their
function.

Applies to vehicles: wit h Aud i adapt ive cr uise contro l
Fig . 111 Examp le: driv ing into a curve
When driving into a curve <=> fig. 111 and out
of a curve, the adaptive cruise control may re­ act to a vehicle in the next lane and app ly the
brakes. You can override or prevent the brak­
ing by pressing the accelerator pedal briefly.
Stationary objects
Applies to vehicles: with Aud i adaptive crui se contro l
Fig. 112 Examp le: object chang ing lanes a nd station ­

The adaptive cru ise control system only reacts
to objects that are moving or that the system
has a lready detected as moving. For example,
if a vehi cle@ , which has already been detect­
ed by the adaptive cruise control, turns or
changes lanes and another stationary vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

106 Audi adap tive cruise control and br aking guard
- If a co llision is imminent, the system will
first provide an
acute warning by bri efly and
sharp ly app ly ing the brakes .
- If you do not react to the ac ute warning ,
braking guard can brake within the limits of
the system. This reduces the veh icle speed
in the event of a collision.
- At speeds under 20 mph (30 km/h), the sys ­
tem can in it iate a complete deceleration
s hortly before a collision
l) .
-If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force.
Which funct ion s can be contr oll ed ?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MM I c> poge 106, Settings in the radio/
MMI.
A WARNING
Lack of attention can cause col lisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collis ion by itself. The
driver m ust always intervene . T he d river is
always responsib le for bra king at the cor­
rect time.
- Always pay close attention to traffic,
even when the brak ing guard is switched
on. Be ready to intervene and be ready to
take complete control whenever necessa­
ry. A lways keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works w ith in limits and
will not respond outs ide the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that

may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving veh icles up ahead may not
be prompt ly detected or may not be de­
tected at all .
- Reflective surfaces including crash barri­
ers or tunne l entrances may impair the
function of the radar sensor .
(D Tips
- You can cancel the braking that is in it iat­
ed by the system by braking yourse lf, by
accelerating not iceably or by swerving .

Audi drive select Driving settings
Introduction
App lies to vehicles: with Audi drive select
Drive select provides the possibility to experi­
ence diffe rent types of vehicle sett ings in one
vehicle. For instance, using the three
Com­
fort, Auto and Dynamic modes, the driver can
switch from a sporty to a comfortab le driving
mode with the press of a button.
Addit ionally, in vehicles with
MM I*, the vehi ­
cle setup for
Individual* mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Applies to vehicles: with Audi drive select
The vehicle setup in each mode depends on
the vehicle's features . However, the engine,
automatic t ransmission* and steering are al­
ways involved.
-
Engine and automatic transmission*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to acce lerator pedal
movements. In the sporty dynamic mode, the
automatic transmission shifts at higher RPMs .
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves easily, like the steering in comfort
mode , is best su ited to long dr ives on a high­
way. In contrast, dynamic mode prov ides
sporty, di rect steering.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on
vehicle speed in order to maintain optimum
Audi drive select 113
steering effort for the driver at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steering
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the veh icle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record
information regarding steering movements,
braking and acceleration operations by the
driver , road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the d riving situation v irtually i n rea l time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortab le suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all whee l dr ive system
(quattro)
~ page 192, the sport differential*
distributes the driving power to the rear axle
depending on the situation . The distribution
of power varies depending on the mode se­ lected. The goal is a high level of agility and
ability to accelerate on curves . The vehicle is
very respons ive to steering .
Audi adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cruise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound*
The sound of the engine is adapted to the se­
lected mode and ranges from subtle to sporty.
0) Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynamic modes.

Approaching another obstacle will result in
the distance warning sounding at the normal
volume aga in.
Malfunctions in the s ystem
If a war ning tone is audible for about five sec­
onds when you turn on the ignit ion, there is a
mal function in the system. Have the problem
corrected by your authorized Audi dealer.
Keep t he sensors in the rear bumper clean and
free from ice so t hat the acoustic park assist
system can function properly.
A WARNING
- Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals ,
since they are not a lways detected by the
sensors.
- The acoust ic park ing system is not a sub­
st itute for the d river's own caut io n and
alertness . Ultimate responsib ility always
remains with the driver during park ing
and simi lar maneuvers. Always watch
whe re you are dr iv ing .
- You should always adjust the volume and
frequency of the warning tones so that
yo u can easily hear the a co ustic distance
warning even if the radio is p laying, the
air-conditioner blower is on High or there
is a high leve l of outside noise.
- Check the settings whenever anyone
else has driven the vehicle before you.
- Remember that low obstacles for wh ich
-
a war ning has a lready been issued may
"dive" below the system's sensing zone if
the veh icle is being backed up closer . In
th is case, the warn ing sound shutt ing off
does
not i ndi cate that you have cleared
the obs ta cl e. Instead, impact is immi ­
nen t.
- Objec ts such as trai ler hitches, c hains,
narrow posts or fences covered by a th in
l ayer of paint may no t always be detect -
Park a ssis t 11 7
ed by the sys tem . They can still damage
your vehicle without warning.
