Assistance systems Speed warning system
Description
App lies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system .
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
A warning tone will sound as soon as your speed
exceeds the stored value slightly. The
(Ol (USA
models)/
(01 (Canada models) indicato r light
and a message appear i n the ins trumen t cluster
d isplay at the same time. The
(Sl (USA models)/
(O] (Canada models) indicator light and the mes ­
sage turn off when the ve hicle speed drops below
the stored maximum speed.
Sett ing a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed . Situations where you may want
to do so include driving in a country with a gener­
al speed limit or if there is a specified maximum
speed for winter tires.

you when the cruise control system is in op­
eration. You are always responsible for your
speed and the distance between your vehi­
cle and othe r vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
w inding roads a nd when road conditions a re
poor (such as ice, fog, g rave l, heavy rai n and
hydroplaning), because this in cr eases the
risk of an acciden t.

when dr iv ing in tu rning lanes, highway exits
or in const ruc tion zones.
-Please no te that uncons ciously "resting"

Audi active lane assist
Description
Applies to: vehicles with Audi active lane assist
Active lane assist detects lane marker lines w ith -
i n the lim its of the system using a camera in the
windshield. If you are approach ing a detected
lane marker line and it appears likely that you
will leave the lane, the system w ill warn you with
cor rective stee ring . You can over ride this stee ring
at any t ime. If you pass ove r a line, the stee ring

wheel will vibrate lightly. In order for this warn­
ing vibration to occur, it must first be switched
on in the Infotainment system. Active lane assist
is ready for operation when the lane marker line
is detected on a t least one side of the vehicle.
The system is design ed for driving on express­
ways and highways and so it only activates at
speeds above approximately 40 mph (65 km/h)
(depending on the market).
Applies to vehicles with side assist* : if you acti­
vate a turn s ignal when active lane assist is ready
and it classifies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there will be noticeable corrective steer ­
in g shortly before you leave the lane . This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist *: the sys­
tem does not warn when it is ready if you activate
the turn signal before crossing the lane marker line. In this case , it assumes that you are chang­
ing lanes intentionally .
A WARNING
- The system warns the driver that the vehicle
is leaving the lane using corrective steer ing.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can assist the driver in keeping
the vehicle in the lane, but it does not drive
by itself. Always keep your hands on the
steering wheel.
- Corrective steering may not occur in certain
situations, such as during heavy braking .
-There may be cases where the camera does
not recognize all lane marker lines . Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected .
-Other road structures or objects could possi­
bly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur .
8 1l The corrective stee rin g func tion is not avail able in all mar­,..._
~ ket s.
Assistance systems
-The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by dirt on the window . This can
result in active lane assist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situations where visibility is low,
the vehicle may switch internally from "ear­
ly " to "late" steering correction
l).
-Under certain conditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steer ing alone may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
potential for hydroplaning. Using active lane
assist under these conditions may increase
the risk of a crash.

rl1 Not read y: the indicator light turns on if the
system is swi tched on but is inoperab le. Th is may
be due to the following reasons:
- There is no lane marker line .
- The relevant lane marker lines are not detected (for example, mark ings in a construction zone
o r because they are obstructed by snow, dirt,
water or lighting).
- The veh icle speed is below the activation speed
of approximately 40 mph (65 km/h) (the speed
may vary depending on yo ur country).
- The lane is too narrow or too wide.
- The curve is too narrow .
- The driver's hands are not on the steering
