8_ WARNING
-Always pay attention to the traffic around
you when the cruise contro l system is in op­
erat ion. You are always respons ible for your
speed and the distance between your veh i­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop -and -go traff ic, on
w inding roads and when road conditions a re
poor (such as ice, fog, gravel, heavy rai n and
hyd roplaning), because this inc reases the
r is k of an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway exits
or in constru ction zones.
- P lease note that "rest ing" your foot on the
accelerator pedal un intent iona lly can result
in ac celeration that overrides the c ruise con-

Side assist helps you monitor your blind spot and
traffic behind your vehicle . Within the limits of
the system, it warns you about vehicles that are
coming closer or that are traveling with you with­
i n sensor range
(D ¢ fig. 79: if a lane change is
classified as critical, the display @in the exter io r
mirror ¢
fig. 80 turns on.
The display in the left exter ior mirror provides as­
sis tance whe n mak ing a lane change to the left,
while the disp lay in the right exterior mirror pro­
vides assistance when making a lane cha nge to
the right .
Information stage
As long as you do not activate the turn signal,
side assist
informs you abou t veh icles tha t are
detected and class ified as crit ical. The disp lay in

Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
I n certain cases, a vehicle will be classified as
cr itica l for a la ne change even if it is still some­
what far away . The faste r a vehicle approaches,
the sooner the display in the exterior mirror will
turn on.
@ Vehicles traveling with you
Veh icles traveling with you are indicated in the
exterior mirror if they are classified as critical for
a lane change. All vehicles detected by side assist
are indicated by the time they enter your "blind
spot", at the latest.
© Vehicles you are passing
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 (lS
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot .
The
display will not tu rn on if you quick ly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are desig ned to detect the left
and right adjacent lanes when the road lanes are
the normal width . In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti ­
cal 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 a 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 vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or displaced guard rails).
- In poor weather conditions . The side assist
functions are limited.
Do not cover the radar sensors
c!:> fig. 82 with
stickers, deposits, bicycle whee ls or other ob-
Assistance systems
jects, because they will impair the function. Do
not use side assist when towing a trai ler. For in­
formation on cleaning, see
c!:> page 185.
A WARNING
=
- Always pay attention to traffic and to the
area around your vehicle. S ide assist cannot
replace a driver's attention. The driver alone
is always respons ible for lane changes and
similar dr iv ing maneuve rs .
- In some situations, the system may not
function or its function may be l imited. For
examp le:
- If vehicles are approaching or being left
behind very quickly. The disp 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 i n 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 impair the system. Have
an authorized Audi dealer or author ized Audi
Service Facility check their funct ion .
(D Tips
- If the window glass in the dr iver's door or
front passenger's door has been tinted, the display in the exterior mirror may be incor­
rect .
- For an explanation on conform ity with the
FCC regulat ions in the United States and the
Industry Canada regulat ions, see
