Stat ionary objects a re d is regarded .
On open roads w ith no traff ic, adaptive cruise
control works like a reg ular cruise control sys- tern.
The sto red speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive c ruise control system a u­
tomat ica lly s lows down to match that vehi­
cle's speed and then maintains the distance
t h at the dr ive r previously stored . As soon as
the sys tem does not detec t a ve hicle up
ah ead, adaptive cru ise cont ro l accelerates
back up to the stored speed.
Which functions can be controlled?
When you switc h adapt ive cru ise control on,
yo u can set the c urrent speed as the ''control
speed " ¢
pag e 93, Switching on and off .
When driving, yo u can stop cru ise contro l

at any time.
You can also set the distance to the object
ahead and set the adapt ive cr uise contro l driv­
ing program

Fig. 100 In str ume nt clus ter: approach wa rning
Braking guard uses a radar sensor. It a lso
funct ions wit hin the lim its of the system
when adapt ive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
s ituations when a vehicle ahea d brakes s ud­
denly o r if your own vehicle is traveling at a
high speed and approach ing a vehicle up
ahead that is moving mo re slowly . Braking
guard does not react if it cannot detec t the
s ituation .
The system advises you of var ious situations:
- The
distance warning is given if yo u are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharp ly , yo u will
not be ab le to avoid a collision . The indicator
light . in the display comes on .
- The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing m uch more slowly than yo u are or if it
brakes s harply . When t his war ning is given,
it may o nly be poss ibl e to avo id a co llision
by swe rv in g or b ra ki ng s harp ly. The indica tor
light . and indicator i n the di spl ay will
warn yo u about the danger ¢
fig. 100. You
w ill also hea r an acoustic signal.
If you do not rea ct fas t eno ugh o r do not r eact
at all t o the si tu at ion, B raki ng g uard will in­
tervene by b raking and the message

wi ll appea r.

Audi adaptive cru ise control and brakin g guar d 97
-If a co llision is imminent, the system will
first provide an
acute wa rnin g by briefly and
sharp ly app lying 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 vehicle speed
in the event of a coll is ion.
- At speeds under 20 mph (30 km/h), the sys­
tem can in it iate a complete decelerat ion
shortly before a collis ion
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 function s can be controll ed?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MM I
¢ page 9 7, Settings in the radio/
MMI.
A WARNING
Lack of attention can cause col lis ions, oth­
er accidents and serious persona l injuries.
The braking guard is an assist system and
cannot prevent a coll is ion by itself. The
driver must always intervene. The d river is
always responsib le for br aking at the cor­
rect time .
- Always pay close attention to traffi c,
even when the bra king g uard is switched
on . Be ready to intervene and be ready to
take complete control whenever necessa­ ry. A lways keep the safe and lega l 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 vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard wo rks only within
defined detection and ra nge limits that
1
> T hi s is not ava ilable in some countries .
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 ve hicles up ahead may not
be prompt ly detected or may not be de­
tected at all.
- Reflective surfaces incl uding crash barri­
ers or tunne l entrances may impair the
function of the radar senso r.
(D Tips
- Yo u can cancel the bra king that is in itiat­
ed by the system by braking yourself, by
accelerating not iceably or by swerving.
- Braking guard error messages
¢page 98.
- Keep in mind that braking g uard can
brake unexpected ly. Always secure any
cargo or objects that you a re tra nsport­
ing to reduce the risk of damage or in­
jury .

•
Fi g. 104 Rear of t he ve hicle: positio n of t he se nsors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e 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 faster a vehicle ap­
p roaches, the sooner the display 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 itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
Audi side assist 101
@ Veh icle s left behind
If you s low ly pass a vehicle that s ide assist has
detected (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.
The disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitation s
The radar senso rs are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the disp lay in the exterior mirror may
turn on even though there is no vehicle locat­
ed in the area that is cr itical for a la ne change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors <=>
fig. 104 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
i nformation on cleaning, refer to<=>
page 196.
_&. WARNING
- Always pay attention to traffic and to t he
area around your ve hicl e. S ide assist can­
not replace a driver's attention. The driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

102 Audi side assist
-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
function.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint­
ed, the display in the exterior mirror may
be misinterpreted.

Park assist
Parking system
Applies to vehicles: wit h pa rk in g 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 107.
The rear parking assist system uses ultrasonic
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 110.
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 m iddle and
two on the sides).
_& WARNING
Make sure the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor function.
For information on cleaning, refer to
qpage 196.
Park assist 107
Parking system (rear)
Rear acoustic park assist
Applies to veh icles: w it h pa rk ing system (rear)
The rear acoustic park assist warns you of ob­
stacles or objects behind your car .
Description
The rear acoustic parking assist 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 sensors 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 warning 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 108.
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 1 ft (0.30 m),
the tone becomes continuous. At this point
you should stop backing up .
Please note that low objects already signalled
by a warn ing 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
gradually reduced after about 4 seconds (this
does not apply in the continous tone range).
ll-

108 Park assist
Approaching another 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
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.
A 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 parking system is not a sub­
stitute for the driver's own caution and alertness . Ultimate responsibility always
remains with the driver during parking
and similar maneuvers. Always watch
where you are driving.
- You should always adjust the volume and
frequency of the warning tones so that
you can easily hear the acoustic distance
warning even if the radio is playing, the
air-conditioner 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 .
{[) Note
-Remember that low obstacles for which
-
a warning has already been issued may
"dive" below the system's sensing zone if
the vehicle is being backed up closer . In
this case, the warning sound shutting off
does
not indicate that you have cleared
the obstacle. Instead, impact is immi­
nent.
- Objects such as trailer hitches, chains,
narrow posts or fences covered by a thin
layer of paint may not always be detect- ed by the system. They can still damage
your vehicle without warning.
(D 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.
