Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
-
The speed warning system warns you if you
are exceeding the max imum speed that you
h ave set . Yo u will hea r a warn ing tone when
your speed exceeds the stored va lue by ap­
p rox imately 3 mph (3 km/ h). The . (USA
models)/ . (Canad a mo dels) indicator l igh t
and the message
Speed limit e xceeded! ap­
pear in the instr ument cluster disp lay at the
same time. The./. indicator light turns
Drivin g 83
off when the speed dec reases be low the stor ­
ed maximum speed .
Setting a t hreshold is recommended if you
would like to be rem inded when you reach a
ce rtain maxim um speed. S ituations whe re you
may want to do so incl ude driving in a co untry
with a genera l speed limit o r if the re is a
specified maximum speed for winter tires .
(D Tips
Regardless of the speed warning system,
you should a lways monitor your speed us­
i ng the speedometer and make sure yo u
are follow ing the lega l speed limit .
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.,.. Select: the
I MENU I button > Car > Systems*
cont ro l button > Driver assistance > Speed
warning .
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adj usted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to veh icles: w ith c ruise control system
The cru ise con trol system makes it poss ib le to
drive at a cons tant speed start ing at 15 mph
(20 km/h).
T he speed is kept const ant by modifying en­
gine powe r or throug h an ac tive brake inte r­
vention .
.&_ WARNING
-Always pay attention to the t raffic
around you when the cruise contro l is in
operation. You are always responsible for
your speed and the distance between
your veh icle and other vehicles .

84 Driving
-For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident .
- Switch the cruise control off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If there is a brake system malfunction
such as overheating when the speed
warning system is switched on, the brak­
ing function in the system will be deacti­
vated. The remaining speed warning sys­
tem functions will remain active, as long
as the
B (USA models)/ ii (Canada
models) indicator light is on.
@ Tips
- The cruise control system is ideal for
stretches with speed limits. The driver is
responsible for adhering to the correct
speed.
- The cruise control remains active when
shifting gears.
- The brake lights turn on when the brakes
are activated.

Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense ba­
sic and pre sense front can initiate steps to
protect vehicle occupants in certain danger ­
ous situations.
Critical driving situations can be recognized by
the pre sense front v ia a network of differe nt
vehicle systems and can take steps to prepare
the vehicle occupants for a potentia l collision.
The pre sense front works with a radar sensor
and a video came ra* .
It also functions within
the limits of the system when adapt ive cruise
control * is switched off.

Audi pre sense basic
Descript ion
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activat­
ed at a speed of 20 mph (30 km/h) or higher.
The following functions can be triggered un­
der certain conditions within the limits of the
system:
- T ensioning of the safety be lts (for example,
during heavy braking) : The front safety belts
have reversib le be lt pretensioners. If a colli­
sion does not occur, the safety belts loosen
s light ly and are ready to trigger again .
- Closing the windows and the sunroof* (for
example, when over- or understeering): The
windows and the sunroof" close until there is only a small gap open. Audi drive select:
The dep loyment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral phys ica l laws.
It is a system designed to
assist and it cannot prevent a coll is ion. Do
not let the increased safety provided
tempt you into taking risks. This could in­
crease your r isk of a collis ion.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certa in pre sense bas ic functions switch
off when ESC is switched off (sport
mode) or when dr iving in reverse .
- The pre sense bas ic functions may not be
available if there is a ma lfunction in the
ESC system or the a irbag control mod­
ule .
- Note that with pre sense bas ic, the rever ­
sible safety belt pretensioner on the
front passenger 's side deactivates when
the front passenger's a irbag is deactivat­
ed.
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi
adapt ive cru ise control
Pre sense front informs yo u if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of a possible collision and initiate braking ma­
neuvers, within the limits of the system .
When detected in time, the system can assess
dangerous situat ions where an object ahead
brakes suddenly or if your own veh icle is trav­
eling at a high speed and approaching an ob ­
ject that is moving more slow ly . If detection is
not possible, then p re sense fro nt does not re ­
act.

Warnings
Applies to vehicles: with Audi pre sense fro nt or Audi
adaptive cruise control
Fig . 85 In strum ent cluste r: approac h warnin g
The system recognizes various dangerous sit­
uat ions :
- Vehicles with adaptive cruise control: The
distance warning occurs if you drive too
closely to the object ahead for a long period
of time.
If the ob ject ahead brakes strongly,
you would not be able to avo id a coll ision.
T he indicato r light . indicates this.
- The
approach warning occurs when an ob­
ject ahead is traveling mo re slowly o r brake s
strongly. When this warning occurs, it may only be possible to avoid a collision by
swerving or braking strongly. The message
Audi pre sense. Distance c::> fig . 85 and a
warning tone will warn you about the dan­ ger. For vehicles with adaptive cruise con­
trol, the. indicator light also turns on.
If you do not react enough or not at all to a
dangerous s ituation that was detected by the
system, pre sense front provides assistance by
applying the brakes .
- If a collision is imminent, the system will
first provide an
acute warning by braking
sharply. You will also be made aware of the
danger by the instrument cluster display
c::> fig. 85. For vehicles with adaptive cruise
control, the. indicator light also turns on .
-If you do not react to the acute warning, pre
sense front can brake with increasing force

-If pre sense front determines that you are
not braking strongly enough when a colli­
sion is imminent, it can increase the braking
force.
A WARNING
--- Pre sense front cannot overcome natural
physical laws.
It is a system designed to
assist and it cannot prevent a collision .
The driver must always intervene. The driver is always responsible for braking
at the correct t ime. Do not let the in­
creased safety provided tempt you into
taking risks. This could increase your risk
of a collision.
- The system can deploy incorrectly due to
system-specific limits .
- Please note that the sensor does not al­
ways detect all objects . This increases
the risk of a collision.
- Pre sense front does not react to people
or animals or objects that are crossing
the vehicle's path or are difficult to de ­
tect
c::> page 86 , General Information.
- Reflective objects such as guard rails or
the entrance to a tunnel, heavy rain and
ice can affect the function of the radar
sensor and the system's ability to detect
a collision risk .
- Lack of attention can lead to collisions,
other accidents and serious injuries. pre

Audi active lane assist
Lane assist
Description
App lies to vehicles: with Audi active lane assist
Active lane ass ist detects lane ma rker lines
within t he lim its of the system using a camera
in the w indshield . If you a re 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 th is warning v ibration 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 wa rns the d river 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.
- 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
marker lines are detected .
l) Th is 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
example 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 .
