- Alw ays remember that the radar sensor
for the b raking guard works only within
defined detection and ra nge limits that
may prev ent the proper det ection of oth­
er ve hicles.
- The ra dar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not
be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent rances may impair the
function of the radar sensor.

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 .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes .
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 .
If the vehicle is also equipped with Audi adap­
tive cruise control*, the corrective steering
will be more specif ic in regard to the driving
situation . In addition to the lane marker lines,
the system can a lso take into acco unt other
objects such as guard rails. If they are detect­
ed in close proximity to the veh icle, Audi a c­
tive lane ass ist helps prevent the vehicle from
driving too close to them . There is also pass­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective
Audi acti ve lane a ssis t 9 1
steering. The driver is always responsible
for keeping the vehicle within the lane.
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. A lways keep your
hands on the steering wheel.
- Corrective steering may not occur in cer­ tain situat ions, such as dur ing heavy
brak ing.
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane ma rker lines. As a result, cor rect ive
steer ing may be unexpected or may not
oc cur .
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
ra in, snow, heavy spray or light s hining
into the camera. This can result in a ctive
lane assist not detecting the lane marke r
lines or detect ing them inco rrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the corrective stee ring alone may
not be enough to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather condit ions such as
slippery roads, fog, gravel, heavy rain,
snow and the potent ial for hydroplaning .
Using act ive lane assist under thes e 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 indicator 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 4 .5 m .
- The curve is too sharp. - The driver's hands are not on the steering
wheel.

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.
@ Vehicles 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
t er your "blind spot", at the latest.

@ Veh icles 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 exterio r mir ror
turns on as soon as the vehicle enters your blind spot.
T he 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 you r
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lan e 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 with stickers,
deposits, bicycle wheels or other objects, be­
cause this will affect the function . Do not use
s ide ass ist when towing a trailer . For informa­
tion on clean ing, refer to
q page 211.
_&. WARNING
-Always pay a ttent ion to traffic and to t he
ar ea a round your ve hicl e. S ide assist can­
not repla ce a driver's attention. The driv­
er a lone is always responsible fo r lane
changes and 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
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 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.
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.

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 level 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 .

@ Tips
-Side assist is not active while you are
making the adjustment.
- Your settings are automatically stored
and assigned to the remote control key
being used.
