ed maximum speed.
Setting a thresho ld is recommended if yo u
wo uld like to be reminded when you reach a
certain maximum speed . Situations where you
may want to do so include d riving in a country
with a general speed limit or if there is a
specified max imum speed for winter tires.
@ Tips
Regard less of the speed warning system,
you shou ld always mon itor your speed us­
ing the speedometer and make sure you
are following the legal speed limit.
Setting the threshold
You con set, change and delete the threshold
in the MMI.

You can set any thresho ld between 20 mph
(30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Appl ies to vehicles : with cruise con trol system
The c ruise control system makes i t possible to
d rive at a constant speed starting at lS mph
(20 km/h).
The speed is kept constant by modify ing en­
g ine power or through an a ct ive brake in ter ­
vention.
A WARNING
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise contro l
should not be used in the c ity, in stop-
Dri vin g 85
and-go traffic, on winding roads and
when road cond itions are poor (such as
ice, fog, gravel, heavy rain and hydro­
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, h ighway
e xits or in construction zones.
- Please note that unconsc iously "resting"
your foot on the accelerator pedal p re­
vents t he cr uise control from b raking.
This is due to the control system be ing
over ridden by the dr iver's acceleration .
- If the re is a brake system malfunct ion
such as overheating when the spee d
warn ing system is switched on, the bra k­
ing f unction in the system w il l be deac ti­
vated . The remaining speed warning sys ­
tem fu nctions will remain active, as long
as the
Ill ( U SA mode ls) I l'I (Canada
models) indicator light is on.
(D Tips
- T he cr uise control system is ideal fo r
st retches wit h speed limits. The driver is
responsib le for adhering to the correct
speed.
- The cr uise control remains act ive when
shift ing gears.
- The b ra ke lights turn on when the b rakes
are act ivated.

Audi active Lane assist Lane assist
Description
Applies to vehicles: with Audi active lane assist
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 will leave the lane, the system will
warn you with corrective steering. You can
override 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 assist is operable when the lane
marker line is detected on at least one side of
the vehicle.
The system will not warn you before crossing
a lane marker line if you have activated the
turn signal. In this case, it assumes that you
are changing lanes intent ionally.
The system is designed for driving on express ­
ways and highways and therefore only acti­
vates at speeds above approximately 40 mph (65 km/h).
_& WARNING
- The system warns the driver that the ve­
hicle is leaving the lane using 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.
- Corrective steering may not occur in cer­
tain situations, such as during heavy
braking.
- There may be cases where the camera
does not recognize all lane marker lines.
Corrective steering can only take place
on the side of the vehicle where lane
marker lines are detected.
,....,
..,., 1) This function is not available in all countries. ,....,
Audi active lane assist 99
-Other road structures or objects could
possibly be identified unintentionally as
lane marker lines. As a result, corrective
steering may be unexpected or may not
occur.
- The camera view can be restricted, for
example 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 detect­
ing the lane marker lines or detecting
them incorrectly.
- In certain situations where visibility is
low, the vehicle may switch from "early"
to "late" corrective steering
l).
-Under certain conditions such as ruts in
the road, an inclined roadway or cross­
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 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 con­
ditions may increase the risk of a crash.
