Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise contro l
The adaptive cruise contro l system assists the
driver by regulat ing vehicle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de ­
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i­
cle . This helps to make driving more comfortable
on long highway stretches .
The braking gua rd system can warn you about an
impend ing collision and initiat e braking maneu­
vers

Adaptive cruise control and braking guard have
technical lim itations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.

The area that contains the radar sensor c:> fig . 92
must never be covered by stickers or other ob­
jects or obstructed w ith dirt, insects, snow or ice
that will interfe re with the adaptive cruise con­
trol system and braking guard. For information
on clean ing, refer to
C) page 184 . The same ap­
plies for any modificat ions made in the front
area . T
he function of the adaptive cruise control sys ­
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
within sensor range
C) page 91 , fig. 95 .
-The sys tem has a l imited ability to de tect ob­
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, ve hicles w ith hig h
ground clearance or overhanging loads may be
detect ed when it is too lat e or they may not b e
detected at all.

,&_ WARNING
-= -Always pay attention to t raffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re­
sponsible for starting and for maintain ing
speed and distance to other objects . Braking
g uard is used to ass ist you . The driver must
a lways take act ion to avoid a co llision . The
driver is always respons ible fo r braking at the
correct time.
- I mproper use of adaptive cruise control can
cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braki ng g uard
offe r distract you from the need to be a lert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adaptive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set d istance when you drive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traff ic jam, a stalled or disabled vehicle .
If reg istered by the radar sensor, vehicles or
obstacles that a re not mov ing ca n trigger a
coll is ion wa rning and if confi rmed by the
video camera, an acute co llision wa rning.

Description
Applies to vehicles: with Audi adaptive cruise co ntro l
Fig. 102 Instrument cluste r: approach warning
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 situat ion.
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 display 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 ib le to avoid a collision by swerving or brak ing
sharply. The indicator light . and indicator in
the display will warn you about the danger
¢ fig. 102 . You will also hear an acoustic signal.
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.

-If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
apply 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 comp lete decelerat ion shortly be­
fore a collision
ll.
- 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 warn ing on or off in the radio or MMI
¢ page 96, Settings in the radio/MM! .
A WARNING
-
Lack of attention can cause collisions, other
accidents and ser ious personal in juries. The
braking guard is an assist system and cannot
prevent a collision by itself. The driver must
always intervene. The driver is always respon­
sible for braking at the correct tim e.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
comp lete control whenever necessary. Al­
ways keep the safe and legal distance be ­
tween 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 veh i­
cle or stationary obstacle (end of a traff ic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only within def ined
detection and range limits that may prevent
the proper detect ion of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be

Fig. 106 Rear of the vehicle: position of the senso rs
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 veh icle app roaches,
the sooner the display in the exterio r mirror w ill
turn on.
@ Vehicles traveling with you
Vehicles traveli ng with you are ind icated in the
exterior mi rror 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 s low ly pass a vehi cle that side assist has
de tected (the difference in speed between the
vehicle 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.
T he display w ill 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
T he 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 d isplaced guard rai ls) .
- In poor weather conditions. The side ass ist
functions are limited.
Do not cover the radar sensors
c:> fig. 106 with
stickers, deposits, bicycle wheels or other ob­
j ects, because th is will affect the f unction . Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to
c:> page 184.
A WARNING
= -
-Always pay attention to traffic and to the
area around your vehicle. S ide assist cannot
replace a driver's attention. The driver alone
is always responsibl e for lane changes and
sim ilar drivin g maneuvers .

Audi side assist
-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 all vehicles under
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 authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

Electronic Stabilization
Control (ESC)
Description
E SC helps to imp rove ro a d hold ing and vehicle
dynamics to help reduce the probab ility of skid­
d ing and loss of veh icle control. It works only
when the engine is runn ing . ESC detects certain
d iffic ult dr iving situat io ns, including when the
ve hicl e is begin ning to spin (yaw) o ut of contro l
a nd h elps you to ge t the veh icle b ack u nder con ­
trol by se lectively braking the wheels, and/or re­
ducing engine powe r and providing steering as­
sistance to help hold the vehicle on the driver's intended course. The indicator light
GI in the in­
strument cluster blinks when ESC is tak ing action
t o he lp you contro l the vehicle.
ESC has lim itations. It is important to remembe r
that ESC cannot overcome the laws of physics. It
will not a lways be able to help out under all con­
d itions you may come up aga inst . For example,
ESC may not always be able to help you master
situations where there is a sudde n change in the
coeff ic ie nt of fr iction of the road surface. W hen
there is a se ction of dry road tha t is sudde nly cov­
e red with w ater, slush o r sn ow , ESC c annot pe r­
form the same way i t wou ld on the dry s urface. If
the vehicle hydrop lanes (rides on a cushion of wa­
ter instead of t he road su rface), ESC wi ll not be
ab le to he lp you stee r the veh icle because contact
with the pavement has been inter rupted and the
ve hicle cannot be b raked or steered . Dur ing fast
cornering, part icu larly on w inding roads, ESC
can not always deal as effect ive ly w it h difficult
d riving situat ions than a t lowe r speeds . When
towi ng a trail er, ES C i s not able to help you re­
g ai n con trol as it would if you we re not towing a
tra ile r.
A lways ad just yo ur speed and driving sty le to
road , tr affic and weathe r cond itions. ESC canno t
override the vehicle's phys ical lim its, incre ase the
170
available tract ion, or keep a vehicle on the road i f
r oad depa rt u re is a res ult of d river inattention .
Instead, ESC improves the poss ib ili ty of keeping
the ve hicle unde r contro l and on the road d uring
extreme maneuvers by using the driver's steer ing
i nputs to help keep the vehicle going in the in ­
tended direction . If you are traveli ng at a speed
t h at causes you to r un off the road before ESC
can p rovide any assista nce, you may not exper i­
ence the benefi ts of ESC.
ESC is switched on all the time. In certa in s itua­
tions when you need less tract ion, yo u can sw itch
off AS R by press ing the button
I!] c:> page 171,
fig. 152 or c> page 171 , fig. 153. Be s ure to
swi tch ASR on again w hen you no longer need
l ess trac tion.
The following systems a re in tegrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braki ng . The vehicle can st ill be steered even d ur­
i ng hard b raking . Apply steady p ressure to the
brake peda l. Do not pump the pedal. A p uls ing in
t h e b rake pedal indica tes th at th e system is help ­
i ng yo u to b rake t he ve hicle.
Brake assist system
The bra ke assist system can decrease braking dis­
ta nce. It increases b raking powe r whe n the dr iver
presses t he br ake peda l quickly i n emergency sit­
u at io ns. Yo u must pre ss and ho ld the bra ke peda l
u nt il t he s itu at ion is ove r. In vehicles wi th adap ­
tive cr uise con trol *, the brake assist sys tem is
more sensitive if t he di stance detected to the ve­
h icle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR redu ces engine powe r whe n the dr ive whee ls
begin to spi n and a da pts the fo rce to the road
con ditio ns. Thi s ma kes it easier to s tart, acce le r­
ate and d rive up hills .
Electronic differential lock (EDL)
The ED L brakes w heels that are spi nning and
t ra nsfe rs the dr ive power to the ot her dr ive
whee l or w heels if the vehicle is equ ipped with
a ll- wheel drive*. This function is not avai lab le at
h ighe r speeds. .,..
