Lane assist
Description
Appl ies to vehicles: with lane assist
Lane assist helps you keep your vehicle in your
lane .
Lane assist detects lane marker lines within
the limits of the system using a camera in the
windshield. If you are approaching a detected
lane marker line and it appears likely that you
will leave the lane, the system will warn you
with a light vibration . Lane assist is operable
when the line marki ng the lane is detected on
at least one s ide of the vehicle .
The system will not warn you before cross ing
a lane ma rker line if you have activated the
turn signal. In t his case, it assumes tha t you
a re cha nging lanes intent ionally.
The system is designed for driv ing on free­
ways and expanded highways and thus works
on ly at speeds of 40 mph (65 km/h) o r more .
.&_ WARNING
-Lane ass ist will not keep your vehi cle in
yo ur lane. The system only warns the
dr iver w hen the vehicle is leaving the
lane . The driver is always responsib le for
keeping the vehicle in the lane .
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines. This can lead to incorrect
warnings or warnings that fail to go off
at all .
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray or light shin ing
in to the camera lens. This can cause lane
a ssist to fa il to detec t bou ndary lines.

that th e system is ready to use . Th e system
can now warn you if yo u are about to cross a
known lane mar ker line.
• Not r ead y: The yellow indicator light
shows that the system is t urned on bu t unable
to send a warning . This can be due to the fol ­
lowing :
- There is no lane boundary line .
- The relevant lane marker lines are not de-
tected (for example, markings in a construc ­
tion zone or because they are obst ructed by
snow, d irt, water or backlighting) .
- The vehicle's speed is below the speed need·
ed to activate it, wh ich is about 40 mph (65
km/h).
- The lane is narrower than about 8
ft . (2.5
m) .

-The curve is too sharp.

is dirty or covered in ice. Clean the area on
the windshield.
- The camera field of v iew is fogged over . Wait
until the fog has cleared before switching
lane assist on .
- The system has been unable to detect the
lanes for an extended period of time due to
road conditions such as lanes covered in
snow . Sw itch lane ass ist back on when the
lines are more visible .

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.

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.

Adjusting the display brightness
App lies to vehicles: wit h side assist
The brightness setting can be adjusted via the
MMI.
.,. Select: I CAR I function button > Car systems
control button
> Driver assist > Audi side
assist .
The display brightness adjusts automatically
to the brightness of the surroundings, both in
the information and in the warning stage . In
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.
Adjust the brightness to a level where the dis­
play in the information stage will not disrupt
your 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
information stage adjustment .

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stability
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 187
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
Ip.] 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
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations 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, traffi<; and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a veh icle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. 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.

Cleaning and protec tion 205
This applies particu la rly to the operating
pre ssure and the spraying di stance. Keep a
distance from soft materia ls such as rubber
hoses or insulating material as we ll as sensors
and camera lenses.
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet.
Water tempera ture sho uld no t exceed 140 ° F
(60 °().
A WARNING
N eve r wash t ires with a jet that sprays wa­
ter in a direct stream . T hi s could cause in ­
v isib le damage to the t ires and weaken
them, even i f the spray is from a re lative ly
long distance and for a sho rt time. Dam­
aged and weakened tires can fail and cause
accidents and personal i njury .
