ically, the i nstrument cluster ind icator goes
out and one of the fo llow ing messages ap­
pears on the display :
Audi active lane a ssist : Curr ently un availa­
bl e. No camera view
This message appears if the camera is no lon­
ger funct ional after the system has cont inous­
ly failed to detect the lane markings . This
could happen if :
- The camera field of view¢
page 102,
fig. 108 is dirty or covered in ice. Clean the
area on the w indshield .
- The camera field of view is fogged over. Wait
until the fog has cleared before switching
active lane assist on .
- The system has been unable to detect the
lanes for an extended period of time due to
road cond it ions . Switch active lane ass ist
back on when the lines are more visible .

As long as you do not activate the turn signal,
side assist
informs you about vehicles that are
detected and class ified as critical. The display
in the respective mirror turns on, but is d im. T
he display remains dim intentionally in the
information stage so that your view toward
the front is not disturbed .
Warning stage
If you activate the turn signal, s ide ass ist
warns you about vehicles that are detected
and classified as critical. The display in the re­
spective mirror blinks brightly . If this hap­
pens, check traffic by glancing in the rearview
mirror and over your shoulder

Fig . 113 Dr iving situations
AUDI
Fig. 114 Rear of t he ve hicle: positio n of t he se nsors
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.
@ V ehicles 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 105
© 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 or
15 km/h), the display in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The 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 or 15 km/h).
Functi onal limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane 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
c> fig. 114 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
c> page 214.
_&. WARNING
- Always pay attention to traffic and to t he
area a round your ve hicl e. S ide assist can­
not replace a driver's attention. T he driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.

106 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 veh icles 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.

very dark or very bright surroundings, the dis­
play is already set to the minimum or maxi­
mum level by the automatic adjustment . In
such cases, you may notice no change when
adjusting the brightness, or the change may
only be noticeable once the surroundings
change.

play in the informa tion stage will not disrupt
yo ur view forward. If you change the bright­
ness, the display in the exterior mirror will
briefly show the brightness leve l in the infor­
mation stage. The brightness of the warning
stage is linked to the brightness in the infor­
mation stage and is adjusted along with the

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of veh icle control. It works
only when the eng ine is running. ESC detects
certain difficult driv ing s ituations, including
when the vehicle is beginning to spin (yaw)
out of cont ro l and helps you to get the vehicle
back under control by select ively brak ing the
wheels, and/or red ucing engine powe r and
p roviding steering assistance to help hold the
ve hicle on the driver's intended course . The in­
dicator light
m in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
phys ics. It will not a lways be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
h elp you master situat ions where there is a
sudden change in the coefficient of fr iction of
the road surface. When there is a sect io n of
d ry road that is s udden ly cove red with water,
slush o r snow, ESC canno t perform the same
way it would on the dry su rface.
If the vehicle
hydroplanes (rides on a c ush ion of wate r in­
stead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because con-
Int ellig ent technolog y 197
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
D uring fast corner ing, particular ly on wind ing
roads, ESC cannot always deal as effectively
with difficult dr iv ing s ituations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
Always adjust your speed and driving style to road, traffic and weather conditions . ESC can­
not override the vehicle's physical lim its, in­
crease the availab le tract ion, or keep a veh icle
o n the road if road departu re is a result of
driver ina ttent io n. Instead , ESC imp roves the
poss ibility of keep ing t he vehicle under con­
trol and on the road during extreme maneu­
vers by using the driver's steering i nputs to
help keep the vehicle go ing in the intended di­
rect ion. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti-lock braking system
(ABS), brake assist
system, anti -slip regulation (ASR), electronic
differential lock (EDL), dynam ic steer ing* and
selective wheel torque contro l. ESC is switch­
ed on all the time. In cer tain situations when
yo u need less traction, yo u can switch off ASR
by press ing the b utton above ~
page 199,
fig. 188 the se lector lever. Be sure to switch
ASR on again when you no longer need less
traction.
Anti -lock braking system (ABS )
ABS prevents the whee ls from loc king up
when b rak ing. The vehicle can st ill be stee red
even during hard braking . App ly steady pres­
su re to the brake peda l. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assi st sy stem
T he brake ass ist system can dec rease braking
distance . It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You must press and hold the
brake pedal unti l the situation is over. In
