2013 AUDI A4 ESP

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.

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 ­
a ry object
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 .
1>.
- 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 must always intervene . The driver 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
l ) Th is is not available in some c oun tri es.
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 .

- Keep in mind that brak ing guard can
brake unexpectedly. Always secure any
cargo or objects that you are transport­
ing to reduce the risk of damage or in­
jury .

(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 ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph
(15 km/h)), the display in the exter io r mirro r
turns on as soon as the vehicle enters your blind spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
T he radar senso rs are des igned 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 fo r a lane cha nge.
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
another la ne that is
not adjacent to your
cur rent lane .
- if you a re driving through a c urve . Side assis t
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. 124 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 tow ing a trail er. For

Audi drive select Driving settings
Introduction
Appl ies to vehicles: wit h Audi drive select
Drive select provides the possibility to experi­
ence different types of vehicle settings in one
veh icle. 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: 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 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 accelerator 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, direct steering.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on
veh icle 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 vehicle . 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
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually 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 wheel dr ive system
(quattro ®)
q poge 191, 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 cru ise 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.

_& WARNING
-Sensors have dead spaces in which ob­
jects cannot be detected. Be especially
alert for small children and animals,
since they are not always detected by the
sensors.
- The acoustic park ing system is not a sub­
st itute for the driver 's own caut ion and
alertness. U ltimate responsibi lity always
remains with the driver during parking
and simi lar maneuvers . Always watch
where you are driving.
- You should always adjust the vo lume and
frequency of the warning tones so that
yo u can easily hear the acoustic distance
warning even if the radio is p laying, the
air-cond itioner blower is on High or there
is a high level of outside noise .
- Check the settings whenever anyone else has driven the vehicle before you.
(D Note
-Remember that low obstacles for wh ich
a warn ing has already been iss ued 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 shutting off
does
not i ndicate that you have cleared
the obstacle . Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a th in
l ayer of paint may not always be detect­
ed by the system. They can still damage
your vehicle without warning.
@ Tips
Keep the sensors in the rear bumper clean
and free of snow and ice so that the acous­
tic parking assist system can function
properly.

- Always keep your eyes on the vehicle's
su rroundings, using the rear view mirror
as well.
- Do not a llow yourse lf to be d istracted
from traffic by the rear view camera pic­
tures.
- If the position and the installation ang le
of the camera has changed, fo r example,
after a rear end collision, do not continue
to use the system for safety reasons. Have it checked by a qua lified dealership.
(D Note
- Low obstacles already signaled by a
warning can disappear from the system's
detection range as they are approached
and will not continue to be signaled . Ob­
jects such as barrier cha ins, trailer draw
