to take complete control whenever nec­essary. Always keep the safe and legal
distance between your vehicle and
vehicles up ahead .
- Pre sense front works within limits and
will not respond outside the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traffic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the pre sense front works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar 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 all.
- Reflective surfaces including crash barri­
ers or tunnel entrances may impair the
function of the radar sensor.
(]) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. The pre sense front sensor can
be damaged by this. Have your authorized
Audi dealer or qualified repair facility
check their function.
@ Tips
- You can cancel the braking with increas­ ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeably or by swerving.

Audi active lane assist
Lane assist
Description
App lies to vehicles: with Audi active lane assist
Active lane ass ist 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 wi ll leave the lane, the system will
warn you with corrective steering. You can
ove rride this steering at any time . If you pass
over a line, the steering wheel will vibrate lightly. In order for this warning vibration to
occur, it must first be switched on in the MMI.
Active lane ass ist is operable when the lane
marker line is detected on at least one side of
the vehicle .
The system will not warn you before cross ing
a lane marker Line if you have activated the
turn signal. In t his case, it assumes that you
a re changing lanes intent ionally.
The system is designed for driv ing on express ­
ways and h ighways and therefore only acti­
vates at speeds above app roximately 40 mp h
(65 km/h).
A WARNING
- The sys tem w arns the d river that the ve­
hicle is leaving the lane us ing corrective
steering . The driver is always responsible
for keeping the vehicle within the lane .
- The system can help you keep the vehicle
in the lane, but it does not drive by itself.
Always keep your hands on the steering
wheel.
- Co rrective stee ring may not occur in cer­
tain situations, such as d uring heavy
braking.
- There may be cases where the camera
does not recognize all lane marker lines.
Corrective steering can only take p lace
on the side of the veh icle where lane
marke r lines a re detected .
l) Thi s func tion is not available in a ll co untries.
- Other road structures or objects cou ld
possibly be identified un intent ionally as
lane marker lines. As a result, correct ive
steer ing 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 light shining into
the camera or by dirt on the window . T his
can result in act ive lane assist not detect­
ing the lane marke r lines or detec ting
them incorrect ly .
- I n certain sit uat ions where visibili ty is
low, the vehicle may swi tch from "early"
to "late" corrective steering
l).
-Unde r ce rtain condi tions such as ruts in
the road, an incl ined roadway or c ross­
winds, the corrective steering alone may not be enough to keep the vehicle in the
middle of the lane.
- For safety reasons, active lane assist
must not be used when the re a re poor
road and/or weather conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning .
Using act ive lane assist under these con­
d itions may increase the risk of a c rash .

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, t he sooner the display in the exteri­
or m irror will t urn on.
@ V ehicles traveling with you

© 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 ro r
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).
Functional limitations
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In some sit ua­
tions, 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 for a lane cha nge.
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 the vehicle in
another lane that is
not adjacent to you r
current lane .
-If you are dr iving through a curve . S ide as­
sis t 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 d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are limited .
Do not cover the radar sensors
c> fig. 88 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. For
information on cleaning, see
c> page 201 .
A WARNING
-Always pay attention to traffic and to the
a rea a round your ve hicl e. Side assi st can­
not repla ce a d river's attention. The driv ­
er a lone is always responsible for la ne
cha nges and s imilar dr iv ing ma ne uvers.
