Audi adapt ive cru ise control and brak ing gu ard
- 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 hydrop lan­
ing). Using the system under these condi­
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac­
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak­
ing guard do not react to people, animals,
objects cross ing the road or oncoming ob­
jects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly. The adap­
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un­
der these conditions.
- To prevent unin tended operation, always
switch ACC off when it is not be ing use d.
(D Note
The sensor can be disp laced by impacts or
damage to the bum per, whee l hou sing and
unde rbody. That could affe ct the adap tive
cruise contro l system and braking guard . Have
your authorized A udi dealer or authorized
Audi Service Facility c heck their function.

Fig. 94 Example: dr iving into a cu rve
When dr iving into a curve c:::> fig. 94 and out of a
curve, the adaptive cruise control may react to a
vehicle in the next lane and apply the brakes. You
can override or prevent the braking by pressing
the accelerator peda l briefly .
Stationary objects

The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, if ave­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary veh icle @ is located in
front of that veh icle, the system will not react to
the stat ionary vehicle.

Audi adaptive cruise control and braking guard
When the adaptive cruise control is turned on,
you must press the clutch to shift gears (as usu­
al). When sh ifting normally or when pressing the
clutch, the adaptive cruise control remains
turned on.
After you have engaged the gear, you do
not need
to press the gas pedal. The adaptive cruise con­
trol accelerates automatically if necessary .
If you press down on the clutch for too long or
shift/coup le im properly, the adaptive cruise con­
trol may turn off automat ica lly.
@ Tips
You cannot turn on the adaptive cruise control
during a shifting operation.
Audi adaptive cruise control
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 96 Detection range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunction
with a rada r sensor installed in the front of the
veh icle¢
page 89, fig. 93, which is subject to
des ignat ed system limits¢
page 91. Stationa ry
objects are disregarded.
On open roads w ith no traff ic, adaptive cruise
control wo rks like a regu lar cruise control system.
The stored speed is mainta ined. When approach­
ing a moving vehicle detected up ahead, the
adaptive cruise control system automatically
slows down to match that vehicle's speed and
then maintains the distance that the driver previ­
ously stored. As soon as the system does not de- tect a vehicle up
ahead, adaptive cruise control
acce lerates back up to the stored speed.
Which functions can be controlled?
When you switch adapt ive cr uise control on, you
can set the current speed as the "control speed"
¢ page 91, Switching on and off.
When driving, yo u can stop cru ise contro l
¢page 93 or change the speed ¢page 92 at
any time.
You can also set the distance to the object ahead
and set the adaptive cruise control dr iv ing pro­
gram ¢

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 103 Instrument cluste r: app roac h warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive 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 suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov ­
ing more slowly . Braking guard does not react if it
cannot detect the s ituation .
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.
in the d isplay comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
s ible to avoid a co llision by swerving or braki ng
sharply. The indicator light . and indicator in
the display will warn yo u about the danger
c> fig. 103. You wi ll also hear an acoust ic signa l.
If you do not react fast enough or do not react at
all to the situation, Braking guard will intervene
by braking and the message
braking guard inter-
~ vention will appear.

This is not available in som e count ries. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collisionl).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
c> page 96, Settings in the radio/MM! .
A WARNING
-
Lack of attention can cause collisions, other
accidents and serious personal injuries. The b raking guard is an ass ist system and cannot
prevent a collis ion by itself. The driver must
always intervene. The driver is always respon­
sib le for b ra kin g at the correct 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 com­
p lete control whenever necessary. Always
keep t he safe a nd legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
f ic).
- Always remember that the radar sensor for
the braking guard works on ly w ithin defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's funct ion and range can
be reduced by ra in, snow and heavy spray.
Moving vehicles up ahead may not be

- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
- You can cance l the braking that is initiated
by the system by braking yourself, by accel­
erating noticeably or by swerving.
- Braking g uard error messages ~

Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faster a vehicle approaches, the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
Audi side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve­
hicle and your vehicle is less than 9 mph (15 km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In certain situations, the dis­
play in the exterior mirror may turn on even
though there is no vehicle located in the area that is critical for a lane change. For example:
- if the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to your current lane.
- if you are driving through a curve. Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the rada r senso rs¢
fig. 107 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function. Do not
u se side assist when towing a trailer. For infor­
mation on cleaning, refer to¢
page 184.
A WARNING
-Always pay attention to traffic and to the
area around your vehicle . Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.

- Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make sure that it is safe to change lanes.
- Side assist cannot detect a ll vehicles under
all conditions- danger of acc ident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your blind spot, only after your vehicle has
reached a dr iv ing speed of at least 19 mph
(30 km/h).
- In certa in situations, the system may not
function or its funct ion may be lim ited. For
example:
- if vehicles are approaching or be ing left
behind very qu ickly. The display may not
turn on in time .
- in poor weather condit ions such as heavy

Driving settings
Introduction
Applies to veh icles: w ith Audi drive select
Drive select provides the possibility to experience
d ifferent types of vehicle settings in one vehicle.
F or instance, using the three
Comfort, Auto and
Dynamic modes, the driver can switch from a
sporty to a comfortable driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehicle
setup for
Individual* mode can be customized by
you. This makes it possible to combine settings
such as a sporty engine tuning with comfortable
steering .
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and serious
personal injury.
Description
Applies to veh icles: w ith Audi dr ive select
-
The vehicle setup in each mode depends on the
veh icle's features . However, the engine, automat­
ic transmission* and steering are always involved.
Engine and automatic transmission*
Depending on the mode, the engine and the au­
tomatic transmission respond quicker or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the au­
tomatic 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
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct stee ring.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on ve­
h icle speed in order to maintain optimum steer­
ing effort for the dr iver at all times. This sets the
s teer ing to be less sensitive at higher speeds in
102
order to provide improved vehicle control. At re ­
duced speeds, however, steering is more direct in
order to keep the steer ing effort as m inima l as
possib le when the driver is maneuver ing the vehi­
cle. At low and average speeds, dynam ic steering
additionally provides more responsive steering
performance.
Adaptive dampers*
The adaptive dampers* use sensors to record in­
formation regarding steering movements, brak­ ing and acceleration operations by the driver,
road surface, driving speed, and load. This makes
i t possible to adapt damp ing to the driving situa­
tion virtually in real t ime . Drive select also makes
i t possible to sat isfy the desire fo r sporty suspen­
s ion (Dynamic) and comfortable suspension
(Comfo rt) without giving up ba lanced tuning (Au­
to).
Sport differential*
As a compone nt of the all whee l dr ive system
(quattro)
<> page 174, t he sport differential* dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the mode selected.
The goal is a high level of agility and ability to ac­
ce lerate on curves. The vehicle is very responsive
to steering.
Audi adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the drive select mode. Adaptive cruise control a lso
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 select­
ed mode and ranges from subtle to sporty.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto and
Dynamic modes.
- For vehicles with an automatic transmis-
sion, se lecting the
Dynamic mode results in 1111-

Parking System
Parking system
Applies to vehicles: with parking system
Different park assist systems may be used for
parking or maneuvering, depending on the vehi­
cle's features.
Parking system (rear)*:
For the parking system (rear), the acoustic park
assist system is installed in the rear of the vehicle
¢page 105.
The rear parking assist system uses ultrasonic
sensors to determine the distance of the vehicle
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 cam­
era),
the rear acoustic park assist system is inte­
grated in the rear of the vehicle and the rear view
camera is integrated in the rear lid ¢page 108.
The parking system (rear, with rear view camera)
uses ultrasonic sensors to determine the distance
of the vehicle from a detected obstacle. There are
a total of four sensors located on the rear bump­
er (two in the middle and two on the sides).
A WARNING
-
Make sure the sensors are not covered by
stickers, deposits or any other obstructions as
it may impa ir the sensor function. For infor­
mation on cleaning, refer to
¢page 184.
Rear parking system
Rear acoustic park assist
Applies to vehicles: with parking system (rear)
The rear acoustic park assist warns you of obsta­
cles or objects behind your car.
Description
The rear acoustic parking assist system deter­
mines the distance o f the vehicle from an obsta-
Parking System
cle using ultrasonic sensors. There are 4 sensors
in the rear bumper.
T he range at wh ich the sensors start to measure
is
about:
To the side 2 ft (0.60 m)
Center rear 5.2
ft (1.60 m)
Activation
Acoustic parking assist is act ivated automatically
when
reverse gear is engaged. A brief tone con­
firms that the system is activated.
Warning tones
Distance warn ing is given by warning tones which
are generated by the rear signal generator. The
vo lume and the p itch of the warning tones can be
adjusted in the MMI*
¢page 106.
Reversing
Distance warning when reversing starts when an
obstacle is detected in the range of the parking
ass ist system . As the distance decreases, the
time interval between the audible tones becomes
shorter.
When the distance is less than 1ft (0.30 m), the
tone becomes cont inuous . At this point you
should stop backing up .
Please note that low objects already signalled by
a warning can d isappear from the system's detec­
tion range and will not continue to be signalled.
If the distance to an obstacle remains the same,
the volume of the distance warning is gradually
reduced after about 4 seconds (this does not ap­
ply in the continous tone range). Approaching an­
other obstacle will result 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 cor­
rected by your author ized Audi dealer.
Keep the sensors in the rear bumper clean and
free from ice so that the acoustic park assist sys-
tem can function properly. .,,.
