Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
driver by regu lating vehi cle 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 vehi­
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an impend ing collision and initiate braking maneu ­
vers
¢ page 95.
Adaptive cruise control and braking guard have
technical limitations that you must know, so
p lease read this section carefu lly, understand
how the system works and use them properly at
all times.

Fig. 93 Fr ont of th e veh icle : Posit ion of radar sensor
The area that contains the radar sensor¢ fig. 93
must never be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or ice
that will inte rfe re with the adapt ive cr uise con­
trol system and brak ing guard. For information
on cleaning, refer to ¢
page 184. The same ap­
p lies for any mod ificat ions made in the front
area. T
he function of the adaptive cruise cont ro l sys­
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
with in sensor range¢
page 91, fig. 96.
-The system has a limited 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, 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

,&_ WARNING
-= -Always pay attention to traffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re­
sponsib le for start ing and for maintai ning
speed and distance to other objects. Braking
g uard is used to assist you . The drive r must
a lways take action to avo id a col lision . The
d river is always responsible for bra kin g at the
cor re ct t ime.
- I mp roper use of adaptive cruise control can
cau se collisions, o ther accidents and serious
pe rsonal injury.
- Never let the comfort and conve nience that
adapt ive cr uise control and braking guard
offer distrac t you from the need to be alert
to traffic con dit ions and the need to remain
i n 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 distance when you dr ive towards an
obstacle or somethi ng on or near the road
that is not moving, such as vehicles stopped
in a traff ic jam, a sta lled or d isabled vehicle.
If registered by the radar sensor, vehicles or
obstacles that a re not moving can t rigger a
coll is io n warning and if confi rmed by the
video came ra, an acute collision war ning.

Fig. 104 Sensor detec tion range
F ig . 105 Displa y on the exte rior mirro r
Side assis t helps you monitor your blind spot and
traffic behind your vehicle . Within the limits of
the system , it warns you about vehicles that are
coming closer or that are traveling with you with­
in sensor range(!)
c:> fig. 104: if a lane change is
classified as critical, the display @ in the exterior
mirror
c:> fig. 105 turns on.
The display in the left exterior mirror provides as­
sistance when mak ing a lane change to the left,
while the disp lay in the right exter ior mirror pro­
vides assistance when mak ing a lane change to
the right .
Information stage
As long as you do not activate the turn signal,
side assist
informs you about veh icles that are
detected and classified as critica l. The display in
the respective mirror turns on, but is dim.
98
The display rema ins dim intentionally in the in­
formation stage so that your view toward the
front is not distu rbed .
Warning stage
If you activate the turn signal, s ide assist warns
you about vehicles that are detected and classi­
fied as critical. The display in the respective mir­ ror blinks brightly . If this happens , check traffic
by g lancing in the rearview mi rror and over your
shoulder

Fig. 107 Rear of the vehicle: positio n of the sensors
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.

Audi side a ssist
- 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
ra in, snow or heavy m ist .
- 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 ar e outside of the sensor
range .
(D Note
The sensors can be displaced by impacts or
damage to the bumpe r, wheel housing and
unde rbody. This can affect the system . Have
your author ized A udi dealer or authori zed

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .
