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 cou ld result in a co lli­
sion.
- Switch adaptive cruise control off tempo­ rar ily when driving in turning lanes, on
expressway exits or in cons truction
zones. This prevents the vehicle from ac­ celerating to the set speed when in these
situations.
- The adaptive cr uise control system wi ll
not brake by itse lf if you p ut your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects
such as stopped traff ic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cruise 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 ve hicle so closely that you
cannot stop your vehicle safely. The
adaptive cruise cont ro l cannot slow or
brake the veh icle safely when you follow
ano ther veh icle too closely. Alway s re­
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
condit ions.
- To prevent unintended operation, always
switch ACC off when it is not being used.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . That could affect the adaptive cruise control system and braking g
uard.
Have your authorized Audi dea ler o r au­
thorized Audi Service Facility chec k their

The adaptive cru ise control system only reacts
to objects that a re mov ing or that the system
has a lready detected as moving . For examp le,
if a ve hicl e@ , which has already been detec t­
ed by the adaptive cru ise con trol , turns or
changes lanes and another stationa ry vehicle
@ is located in front of that vehicle, the sys­
tem will not react to the stationary vehicle.

Description
Applies to vehicles: with Audi adap tive cruise control
Fig. 106 Detect ion range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunc­
tion with a radar sensor installed in the front
of the vehicle
c::> fig. 103, which is subject to
des ignated system limits
c::> page 96. Station­
a ry objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control works like a regu lar cruise control sys­
tem. The stored speed is main tained. When
approaching a moving vehicle detected up
ahead, the adaptive cruis e control system au­
tomatically s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previous ly stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates
back up to the stored speed .
Which functions can be controlled?
When you switch adaptive cruise contro l on,
you can set the current speed as the "control
speed"
c::> page 96, Switching on and off.
When driving, you can stop cruise control
c::> page 98 or change the speed c::> page 9 7
at any time.
You can a lso set the distance to the object
ahead and set the adaptive cruise control driv ­

Descript ion
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off .
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
guard does not react if it cannot detect the
situation.
The system advises you of various situations :
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will
not be able to avoid a collision. The indicator
light
I in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­ ing much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possib le to avoid a collision
by swerving or braking sharply . The indicator
l ight
I and indicato r in the display will warn
you about the danger
¢ fig. 113 . You will al­
so hear an acoustic signal.

- If a coll is ion is imminent, the system wi ll
fi rst provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision .
- At speeds under 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration

).
- If the braking guard senses that you are not
brak ing hard enough when a co llision is im­
minent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MMI
¢ page 101, Settings in the radio/
MMI.
A WARNING
-Lack of attention can cause collisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The dr iver is
always responsible for braking at the cor­
rect time .
- Always pay close attent ion to traffic,
even when the braking guard is switched
on. Be ready to intervene and be ready to
take complete control whenever necessa­
ry. Always keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in t raffic).

Audi adaptive cru ise control and brakin g guar d 101
-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 vehicles up ahead may not be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.
- Bra king guard error messages

-Keep in mind that braking guard can
brake unexpectedly . Always secure any
ca rgo or objects that you are transport­
i ng to reduce the risk of d amage or in ­
ju ry.

(D V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted (t he difference in s peed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h), the display in the exter ior mirror
turns on as soon as the vehicle enters your
blind spot.
The display wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (the dif ­
ference in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h).
Functional lim itations
T he radar senso rs are designed to detect the
left and right adjacent lanes whe n the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on
even though there is no ve hicle locat­
ed in the area that is cr itical for a la ne cha nge.
Fo r example:
- if the lanes are narrow or if your are driving
on th e edge of your lane. If this is the case,
the system may have detected the vehicle in
another la ne that is
not adjacent to you r
cur rent lane .
- if you a re driving throug h a c urve . Side assist
may react to a vehicle that is one lane ove r
from the ad jacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist
fu nctions are limited .
Do not
cover the radar sensors c::> fig. 117 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer . For

-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly. The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface .
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system .
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their

Audi drive select Driving settings
Introduction
Appl ies to vehicles: wit h Audi drive select
Dr ive select provides the possib ility to experi­
ence different types of vehicle settings in one
veh icle. For instance, using the three
C o m­
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
Indi vidu al* 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
App lies to vehicles: w it h Audi drive select
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission and steeri ng a re a l­
ways involved.
-
Engine and automatic transmi ssion
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 t ransmission shifts at h igher R PMs .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steer ing that
moves eas ily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high ­
way. In contrast, dynam ic mode prov ides
sporty, di rect steering .
The follow ing applies to vehicles with dynam ic
steer ing*: the stee ring ratio changes based on
vehicle speed in order to maintain optimum
Aud i dri ve sel ect 107
steering effort for the drive r 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, steer ing
is more d irect in order to keep the steering ef­
fort as minimal as poss ible when the driver is
maneuveri ng the veh icle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive stee ring pe rformance.
Adapt ive damper s*
The adaptive dampers* use sensors to record
i nformation regard ing steering movements,
braking and acceleration ope rations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the d riving situation v irtu ally i n rea l time.
Drive select also makes it possib le to satisfy
the desire for spo rty suspension (Dynamic)
and comfortab le suspension (Comfort) with­
out giving up ba lanced tuning (Auto) .
Sport differe ntial *
As a component of the all whee l dr ive sys tem
(quattro ®)
q page 184, the sport differential*
distributes the driving power to the rear ax le
depending on the sit uation . The distribution
of power var ies depending on the mode se­
lected. The goal is a high level of agility and
ability to accelerate on curves . The ve hicle is
very respons ive to steering .
Audi adaptive cru ise control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise control
also responds to the driv ing behavior of the
vehicle ahead in a mo re conservative or spo rty
manner .
Engine sound*
The sound of the eng ine is adapted to these­
lected mode and ranges from subtle to sporty.

- In some models, the maximum vehicle
speed can only be reached in the
Auto
and D ynamic modes.

110 Park assist
Park assist
Parking system
Applies to vehicles: with pa rking system
Different park assist systems may be used for
parking or maneuvering, depending on the
vehicle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic
park assist system is installed in the rear of
the vehicle
¢ page 110.
The rear parking assist system uses ultrason ic
sensors to determine the distance of the vehi­
cle from a detected obstacle. There are a total
of four sensors located on the rear bumper
(two in the middle and two on the sides).
Parking system (rear, with rear view
camera)*:
For the parking system (rear, with rear view
camera),
the rear acoustic park assist system
is integrated in the rear of the vehicle and the
rear view camera is integrated in the rear lid
¢page 113.
The parking system (rear, with rear view cam­
era)
uses ultrasonic sensors to determine the
distance of the vehicle from a detected obsta­
cle . There are a total of four sensors located
on the rear bumper (two in the middle and
two on the sides).
Parking system (rear)
Rear acoustic park assist
App lies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of ob­
stacles or objects behind your car.
Description
The rear acoustic parking ass ist system deter­
mines the distance of the vehicle from an ob­
stacle using ultrasonic sensors. There are 4
sensors in the rear bumper.
The range at which the senso rs start to meas­
ure is
about :
To the side 2 ft (0.60 m)
Center rear 5.2 ft (1.60 m)
Activation
Acoustic parking assist is activated automati­
ca lly when
reverse gear is engaged. A brief
tone confirms that the system is activated.
Warning tones
Distance warning is given by warn ing tones
which are generated by the rear signal genera­
tor. The volume and the pitch of the warning
tones can be adjusted in the MMI*
¢page 111.
Reversing
Distance warning when reversing starts when
an obstacle is detected in the range of the
parking assist system . As the distance de­
creases, the time interval between the audible
tones becomes shorter.
When the distance is less than 1ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a warning can disappear from the system's
detection range and will not continue to be
signalled .
If the distance to an obstacle remains the
same, the volume of the distance warning is
gradua lly reduced after about 4 seconds (this
does not apply in the continous tone range).
Approaching another obstacle will resu lt in
the distance warning sounding at the normal
volume again.
Malfunctions in the system
If a warning tone is audible for about five sec­
onds when you turn on the ignition , there is a
malfunction in the system. Have the problem
corrected by your authorized Audi dealer.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist
system can function properly.
