Audi active Lane assist
Active Lane assist
Description
Applies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane.
Active lane assist detects lane marker lines
within the limits of the system using a camera in the windshield . If you are approaching a de
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
driver can over ride the cor re ct ive steer ing at
any time. If the veh icle crosses a line, the d riv
er is also warned by a light
vibration in the
steering whee l. The vibration warning must
be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
The system is designed for driv ing on free
ways and expanded highways and thus works only at speeds of 40 mph (65 km/h) or more .
Applies to vehicles with side assist* : If you ac
tivate your turn s ignal when active lane assist
is ready and when activated side assist has
classified a lane change as crit ica l because of
vehicles traveling alongside you or comi ng
closer, there will be noticeable correct ive
steer ing just before you leave the lane . This is
done to try to keep your veh icle in the lane.
Applies to vehicles w ithout s ide ass ist*: when
the system is ready, it does not warn you if
you act ivate your turn signa l before driving
across a lane marker line . In this case, it as
sume s that yo u are ch ang ing lanes intent ion
a lly.
I f the vehicle is also equipped with Audi adap
tive cruise cont ro l*, the co rrec tive steering
will be mo re specific in rega rd to the driving
situation. In addition to the lane marker lines,
the system can a lso take into account other
objects such as guard rails . If they are detect
ed in close proximity to the veh ic le, Audi ac-
Audi acti ve lane a ssis t 10 1
tive lane assist he lps prevent the vehicle from
driving too close to them. There is a lso pass
ing ass istance . The system does not provide
any correct ive steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the drive r that the ve
hicle is leaving the lane using co rrect ive
s teer ing . The d river is always r esponsible
for keeping the vehicle withi n the lane.
- The system can assist the dr iver in keep
i n g the vehicle in the lane, but it does
not steer by itself. A lway s keep yo ur
h a nds on the steering wheel.
- Cor rective s teer ing may not occur in cer
tain sit uat ions, such as dur ing heavy
bra king.
- Th e camera does not recogni ze all lane
marker lines. Cor rective s teer ing ca n only
take p lace on the side of the vehi cle
where lane marke r lines are detected.
- Othe r road str uctures o r objects co uld
possibly be identified unintentiona lly as
lane ma rker lines . As a res ult, corrective
steering may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead or by
ra in, snow, heavy spray or light shining
into the camera . Th is can result in act ive
lane assis t not detecti ng the lane marke r
lines or detect ing them inco rrectly.
- Unde r ce rtain conditions such as ruts in
the road, a banked roadway or cross
winds, the co rrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
m ust not be u sed w hen the re a re poor
road and/or weat her condi tions such as
slippe ry roads, fog, grave l, heavy rain,
snow an d the potential for hydroplaning .
Using active lane assist under these con
ditions may increase the risk of a crash.

system is ready to use . The system can now
warn you if you are about to cross a known
lane marker line .
• Not ready: The ind icator light shows that
the system is turned on but unable to send a
warning . This can be due to the following :
- There is no lane marker line .
- The relevant lane marker lines are not de-
tected (for example, markings in a construc
tion zone or because they are obstructed by
snow, dirt, water or backlight ing).
- The vehicle 's speed is below the speed need
ed to activate it, which is about 40 mph (65
km/h) .
- The lane is narrower than about 8 ft . (2 .5 m)
or wider than 15 ft (4 .5 m).
- The curve is too sharp . - The driver's hands are not on the steering

- The camera field of view is fogged over. Wait
until the fog has cleared before switching

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.
