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 via a network of different
vehicle systems and can take steps to prepare
the vehicle occupants for a potential collision.
The pre sense front works with a radar sensor
and a video camera*.
It also functions within
the limits of the system when adaptive 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 10 mph (30 km/h) or higher.
The following functions can be triggered un
der certain conditions within the limits of the
system:
- Tensioning of the safety belts (for example,
during heavy braking) : The front safety belts
have reversible belt pretensioners. If a colli
sion does not occur, the safety belts loosen
slightly 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 deployment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral physical laws.
It is a system designed to
assist and it cannot prevent a collision. Do not let the increased safety provided
tempt you into taking risks. This could in
crease your risk of a collision.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certain pre sense basic functions switch
off when ESC is switched off (sport
mode) or when driving in reverse .
- The pre sense basic functions may not be
available if there is a malfunction in the
ESC system or the airbag control mod
ule .
- Note that with pre sense basic, 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 you 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 situations where an object ahead
brakes suddenly or if your own vehicle is trav
eling at a high speed and approaching an ob
ject that is moving more slow ly . If detection is
not possible, then pre sense front does not re
act.

Warnings
Applies to vehicles: with Audi pre sense fro nt or Audi
adaptive cruise control
Fig . 80 Instrument cluster: approach warning
The system recognizes various dangerous sit
uations:
- 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 object ahead brakes strongly,
you would not be able to avoid a collision.
The ind icator light . indicates this.
- The
approach warning occurs when an ob
ject ahead is traveling more slowly or brakes
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 . 80 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. 80. 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

lision. The message Audi pre sense -Input
also appears.
- At low driving speeds, pre sense front can
begin complete deceleration shortly before
a collision
l) .
-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 82, 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 cause collisions,
other accidents and serious personal in
juries. The pre sense front is an assist
system and cannot prevent a collis ion by
itself. The driver must always intervene.
The driver is always responsib le for brak
ing at the correct time.
- Always pay close attention to traffic,
even when the pre sense front is switch-
ed on. Be ready to intervene and be ready .,_

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.
- Driver messages about pre sense
¢page 92.
- Keep in mind that pre sense can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to re
duce the risk of damage or injury.
- Certain pre sense front functions switch off when ESC is switched off (sport
mode) or when driving in reverse. -
The pre sense front functions are not
available if there is a malfunction in the
adaptive cruise control* system

94 Audi acti ve lan e assi st
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 .
