Audi adaptive cruise
control
Description
Applies to vehicles: with Audi adap tive cruise co ntrol
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 90, fig . 103, which is
subject to designated system limits
¢page 92. Stationary objects are disregard­
ed .
On open roads w ith no traffic, adaptive cruise
control works like a regular c ruise 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 contro l on,
you can set the current speed as the "control speed"
¢ page 92, Switching on and off.
When driving, you can stop cruise control
¢
page 94 or change the speed ¢ page 93
at any time.
You can also set the distance to the object
ahead and set the adaptive cruise control driv­ ing program

Audi braking guard
Descript ion
Applies to vehicles: with Audi adaptive cru ise control
Fig . 11 3 Instrumen t cl uste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise cont ro l is switched off .
What can Audi braking guard do? When detected i n time, the system ca n assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
hi gh speed and approachi ng a ve hicle up
a head that is moving more slowly . Brak ing
guard does not react if i t can not detect the
situation.
The system advises you of various situations :
- The distance warning is given if you are too
close to t he vehicle ahead for a long time . If
the vehicle ahead b rakes sharply, you w ill
not be ab le to avoid a c oll is io n. The indicator
li ght . i n the disp lay comes o n.
- The approach warning is given when a de ­
tected vehicle up ahead in your lane is mov­ i ng much more slowly tha n you are or if it
brakes sha rply . W hen th is w arning is given,
i t may only b e possib le to avoid a collision
b y swerving or braking s harply . Th e in dicator
l igh t. and indic ator in the di sp la y w ill

-Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
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 vehicles up ahead may not be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.

100 Audi side assist
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
cr itica l for a lane change even if it is still
somewhat far away . The faster a vehicle ap­
proaches, the sooner the display in the exteri ­
or mirror will turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior m irror if they are classified as critica l
for a lane change. All vehicles detected by
side assist are indicated by the time they en­
ter 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
vehicle and your vehicle is less than 9 mph
(15 km/h)), the disp lay 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 dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to de tect the
l eft and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the display in the exterior mirror may
turn on even though there is no vehicle locat­
ed 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
another lane that is
not adjacent to your
current lane.
- if you are driving through a curve. Side assist
may react to a veh icle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard ra ils). -
In poor weather conditions . The side assist
functions are limited.
Do not cover the rada r sensors
~ fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . For
information on cleaning, refer to ¢
page 184.
A WARNING
-
-Always pay attention to traffic and to the
area around your vehicle. Side assist can­
not replace a driver's attention. The driv­
er alone is always responsible for lane
changes and similar dr iving maneuvers .
- Improper reliance on the side assist sys­
tem can cause coll is ions and serious per­
sonal injury:
- Never rely on ly 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 sit uations, the system may not
function or its function may be limited.
For example:
- if vehicles are approach ing or being left
behind ve ry quickly. The d isp lay 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 .
([) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
u nderbody. This can affect the system. .,..

rear view came ra
Fig. 126 Trunk lid : Locatio n of the rear view camera
Sensors in the bumper
Sensors are located in the front and rear
bumpers. If these detect an obstacle, audible
and visual signals warn you. The range at
which the sensors begin to measure is approx­
i mately :
side 3
ft (0.90 m)
front center 4
ft (1.20 m)
side 2
ft (0.60 m)
rear center 5 .2 ft (1.60 m)
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 interva l between the audib le
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.
If the d istance to an obstacle stays the same,
the volume of the distance signal chime is
gradually reduced after about 4 seconds (does
Park assist 107
not affect the continuous signal tone). Ap­
proaching another obstacle will cause the dis­
tance signal to sound again at the norma l vo l­
ume .
Rear view camera coverage area
The MMI display shows the area covered by
the rear view camera
c:> fig. 125 (!). Objects
that are not in the area covered @are not
shown on the MMI display .
We recommend that you practice parking with
the rear view camera in a traffic-free location
or parking lot to become familiar with the sys­
tem, the orientation lines, and their function.
When doing this, there should be good light
and weather cond itions.
In the MMI display, objects or vehicles appear
closer or further away if:
-you are driving in reverse gear from a leve l
surface onto an incline, or a downward
slope,
-you are driving in reverse gear toward pro­
trud ing ob jects,
- the vehicle is car ry in g too much load in the
rear.
The accuracy of the orientation lines and blue
surfaces diminishes if:
- the rear view camera does not provide a reli­
able image, for example, in poor visibility
conditions or if the lens is dirty,
- the image on the screen is not vis ible due to
sun glare and reflection.
Caring for the rear view camera lens
The rear view camera is located above the rear
license plate bracket. For the parking assist to
operate, the lens
c:> fig . 126 must be kept
clean:
- Dampen the lens with a household alcohol­
based glass cleaner, and clean the lens with
a dry cloth
