Description
Applies to vehicles: with Audi adap tive cruise co ntrol

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
¢page 94.

A WARNING
Improper use of the adaptive cruise con­
trol can cause collisions, other accidents
and serious personal injuries.
- Pressing the
!SET ! button when driv ing at
speeds below 20 mph (30 km/h), w ill au­
tomatically accelerate the vehicle to
20 mph (30 km/h), which is the mini­
mum speed that can be set.
@ Tips
-If you switch the ignit ion or the adaptive
cruise control off, the set speed is erased
from the system memory.
- The electronic stab ilizat ion control (ESC)
and the anti-slip-regulat ion (ASR) are au­
tom atica lly turned on when the adaptive
cruise control is turned on. Both systems
cannot be turned off if the adaptive

A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing your vehicle to a safe
stop and ma kes it
even more necessary
to pay close attention to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing distance for the traffic, road and
weather conditions .

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. .,..

moves easi ly, like the stee ring in comfort
mode , is best su ite d to long dr ives on a high ­
way. In contrast, dynam ic mode p rov ides
sporty, d irect steering. T
he following app lies to veh icles with dynamic
stee ring *: the steering rat io chan ges base d on
vehicle speed in order to ma inta in optim um
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in o rder to provide improved vehicle
co ntrol. At r educed speeds, howeve r, s teer ing
is mo re d irect in o rder to k eep th e stee ring ef­
