Audi adaptive cruise
control
Description
A pp lies to vehicles: with Audi adaptive cruise control
Fig. 106 Detect ion range
What can Audi adaptive cruise control do?
The adaptive cruise control works in conjunc­
tion with a radar sensor installed in the front
of the vehicle ¢
page 93, fig . 103, which is
subject to designated sys tem limits
¢
page 95. Stationary objects are disregard­
ed .
On open roads w ith no traffic, adaptive cruise
control wo rks like a regular cruise control sys­
tem. The stored speed is maintained. When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au ­
tomatically slows down to match that vehi­
cle's speed and then maintains the distance
that the driver previously stored. As soon as
the system does not detect a vehicle up
ahead, adaptive cruise control accelerates back up to the stored speed.
Which functions can be controlled?
When you switch adaptive cruise control on,
you can set the current speed as the "control speed" ¢
page 95, Switching on and off.
When driving, you can stop cruise control
¢
page 97 or change the speed¢ page 96
at any time .
You can a lso set the distance to the object
ahead and set the adaptive cruise control driv­ ing program

Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 113 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive 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 sud­
denly or if your own vehicle is traveling at a high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
gua rd does not react if it cannot detect the
situation .
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 wi ll
not be able to avoid a collis ion. 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 much more slowly than you are or if it
brakes sharply . When th is warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. Th e indicator
light. and indicator in the display will
warn you about the danger
c::> fig. 113. You
will a lso hear an acoustic signa l.
If you do not react fast enough or do not react
at all to the situation, Braking guard will in-
ll This is not ava ilable in som e coun tri es.
tervene by braking and the message braking
guard intervention will appear.
- If a coll ision is imminent , the system will
first provide an acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the lim its of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds unde r 20 mph (30 km/h), the sys­
tem can initiate a comp lete deceleration
shortly before a collision
ll.
- 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 functions can be controlled?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or M MI
c::> page 100, Settings in the radio/
MMI.
A WARNING
-Lack of attention can cause collisions, oth-
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The dr iver is
always respons ible for braking at the cor­
r ect time .
- 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 necessa­
ry. Always keep the safe and legal dis­
tance between your vehicle and vehicles up ahead.
- Braking guard works within limits and
will not respond outside the system lim­
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traffic).

- Always remember t hat t he radar sens or
fo r the braking guard wo rks only within
defined detection and range limits that
may preve nt the proper detection of oth­
er v eh icles.
- The radar senso r's fu nction and range
can be reduced by rain, s now a nd heavy
spray. Mo ving v ehicl es u p ahead may not

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 fas ter 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 103
@ Veh icle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r 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 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 veh icle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
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. 117 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 195.
_&. WARNING
- Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can­
not repla ce a driver's attention. T he driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

104 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.

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 109.
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

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 110.
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-

110 Park assis t
Approaching another obstacle will result in
the distance warning sounding at the normal
volume aga in.
M alfunction s in the syst em
If a warning tone is audible for about five sec­
onds when you turn on the ignit ion, there is a
mal function 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
- Senso rs have dead spaces in which ob­
jects cannot be detected. Be espec ially
alert for small children and animals,
since they are not a lways detected by the
sensors.
- The acoust ic park ing system is not a sub­
st itute for the driver's own caut ion and
alertness . Ultimate responsib ility always
remains with the driver during park ing
and simi la r maneuve rs. Always watch
w here you are driving.
- You should always adjust the vo lum e and
frequency of the warning tones so that
yo u can easily hear the a co ustic distance
warning even if the radio is p laying, the
air-conditioner blower is on High or there is a high leve l of outside noise.
- Check the settings w henever anyone
e lse has driven the vehicle before you .
{[) Note
-Remember that low obstacles for wh ic h
-
a war ning has a lready been issued may
"d ive" below the system's sensing zone if
t h e veh icle is being backed up closer . In
th is case, the warn ing sound shutt ing off
does
not i ndicate that yo u have cleared
the obs tacle. Instead, impact is immi ­
nent.
- Objec ts such as trai ler hitches, c hains,
nar row posts or fen ces covered by a t hin
l aye r of paint may not a lways be detect -ed by the system
. They can still damage
your vehicle without warning.
(D Tips
Keep the senso rs in the rear b umpe r clean
