88 Audi adapti ve cruise control and bra king gu ard
vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones . This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and d istance regulation .
- When approaching stationary objects such as stopped traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing the vehicle to a
sudden or emergency stop under these condit ions.
- To prevent unintended operation, always switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.
Have your authorized Aud i dea ler or au ­
thorized Audi Service Facility check their
funct ion .

Applies to vehicles: with lane assist
You can adjust individual settings in the MMI.
.. Se lect: ICARI funct ion button> Car systems
control button > Driver assist > Audi lane
assist .
Setting the warning point
Early: With this setting, a warning is provided
before a wheel touches the detected lane
boundary line . The warning depends on the
angle in which the veh icle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you dr ive towa rd a bounda ry line at a very
sha rp angle, the warning will come just before
a wheel touches the line.
Medium : With this setti ng, the warn ing po int
is adapted to the course of the road, the lane
width and the speed. You wi ll sti ll be warned
if you cross slightly over a dotted line when
driving on curves.
Late : This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel v ibration can be set to
Low , Medium or Strong . Selecting each of the
settings will cause the steering wheel to vi­
b rate so you can check the strength of the vi­
bration in that setting.
(D Tips
Your settings are automatically stored and
assigned to the remote contro l key being

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
(D V ehicles that are 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 ro aches, the sooner the disp lay 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 it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph or
15 km/ h), the display in the exterio r mirror
turns on as soon as the vehicle enters your blind spot.
The disp lay wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph or 15 km/h).
Functional limitations
T he radar senso rs are designed to detect the
left and right adjacent lanes when the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on even though there is no ve hicle locat­
ed in the area that is cr itical fo r a la ne cha nge.
Fo r 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 you r
cur rent lane .
- if you a re driving through a c urve . Side assis t
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 gua rd rails) .
- In poor weather conditions. The side assist
fu nctions are limited .
Do not cover the radar sensors
c::> fig. 104 with
stickers, depos its, bicycle wheels or other ob­
jects, because this wi ll affect the funct io n. Do
not use s ide ass ist when towing a trailer . For
information on cleaning, refe r to
c::> page 205 .
&_ WARNING
-Always pay a tten tion t o traffic and to the
a rea around your ve hicl e. Side a ssist can ­
no t repla ce a driver's atte ntion. The driv ­
er a lone is always respons ible fo r lane
cha nges a nd similar driving mane uvers.

-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 vehi­ cles in your blind spot, only after your ve­
hicle 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 . Vehi­
cles in the adjacent lane may not be de­
tected 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.
(D 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.

112 Automatic Transmission
When parking on a level surface, simply place
the selector lever in the P position. On slopes,
activate the parking brake first and then
move
the selector lever to the P position. This pre­
vents too much stress from being placed on
the locking mechanism.
A WARNING
Read and follow all WARNINGS Q .&. in Se­
lecting a selector lever position on
page

- Do not press the accelerator pedal when
changing the selector lever position
wh ile the vehicle is stationary and the
engine is ru nn ing. This could result in a
crash .
- Never engage R or P while driving.
It
could cause a crash .
- Power is still transmit ted to the whee ls
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake in all
selector lever positions except P and N
when the engine is running. Do not inad­
vertently press the accelerator pedal
when the veh icle is stationary . Otherwise
the vehicle will start to move immediate­
ly, even if the parking brake is set. This
could result in a crash.
Kick-down
Kick-down enables maximum acceleration .
When you press the accelerator pedal down
beyond the resistance point , the automatic
transmission downshifts into a lower gear, de­ pending on vehicle speed and engine RPM.
It
shifts up into the next h igher gear once the
maximum specified engine RPM is reached .
A WARNING
Please note that the wheels could spin on
slic k or slippery roads when kick-down is
active.
Shifting manually
The shift paddles allow the driver to shift the
gears manually .
