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.

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

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

also app ears .
- 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 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
sense front is an assistance system and
cannot prevent a collision by itself . The
driver must always intervene . The driver
is always responsible for braking at the
right time.
- Always pay attention to traffic, even
when pre sense front is switched on. Al-
ways be ready to intervene and take over
comp lete control of the vehicle whenever .,.

it is necessary. A lways follow traffic laws
regarding mainta ining a safe distance
between your vehicle and vehicles ahead.
- pre sense front works within certain lim­
its and cannot react to situations that
are outside of the system lim its, such as
when approaching a stationary vehicle or
a stationary obstacle (the end of a traffic
jam or a vehicle that has broken down).
-Always keep i n m ind that the radar sen­
sor fo r pre sense front only works within
defined detection zones, which mea ns
other vehicles may not always be dete ct­
ed correct ly.
- T he function and range of the radar sen­
sor can be impaired by rain, snow and
heavy mist. Veh icles ahead may not be
detected right away, or not detected at
all.
- Reflective surfaces such as g uard rails or
entrances to t unnels may impair the
function of the radar sensor .
{[) Note
The senso r can be disp laced by impacts or
damage to the bumper, whee l housing and
underbody . The pre sense front sensor can
be damaged by this . Have your authorized
Aud i dea ler or authorized service facility
check the ir function.
(D Tips
- You can cance l the braking w ith increas­
ing force that is initiated by the system
by braking yourself, by accelerating no­
ticeab ly or by swerving.
- For information on dr iver messages
about pre sense, refer to¢ page 96.
- Keep in mind that pre sense can brake unexpectedly. Always secure any cargo or
objects that you are transporting to re­
duce the r isk of damage or injury .
- Certain pre sense front funct ions sw itch
off when ESC is sw itched off (sport
mode) or when drivi ng in reve rse .
- The pre sense front funct ions are not
available if there is a malfunction in the adaptive cru
ise cont ro l* system

Hill descent control
App lies to vehicles : wi th 5 tronic tra nsmi ssio n
Hill descent control assists the driver when
driving down hills .
Hill descent control is activated when these­
l ector lever is in the D or S position and you
press the brake peda l. The transmission auto ­
matically selects a gear that is suitable for the
i ncl ine. Hill descent cont ro l t ries to ma inta in

within physic al and tec hnical lim it a tions. If
may sti ll be ne cessa ry to adju st the speed
with t he b rakes . Because hi ll descent control
cannot sh ift down farthe r than 3rd gear, it
may be necessary to sh ift into t iptronic mode
in very steep areas. In this case, shift into 1st
o r 2nd gear in tiptro nic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent control switches off once the hi ll
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*

Smart Technology
Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is installed by some vehi­
cle manufacturers to record data about crash­
es so that it can be analy zed later . Crash data
recorders are also called "Event Data Record­
ers ( EDR)" .
In some legal jurisdictions, it is not permitted
to access or download data recorded by pre­
installed crash data recorders in order to eval­
uate a crash without clear consent of the vehi ­
cle owner .
Your vehicle is not equipped with a crash data recorder. However it does contain a variety of
electronic control modules for various vehicle
systems such as engine function, exhaust
treatment or airbags and safety belts .
These electronic control modules record vehi­ cle data during normal driving for diagnosis
and repair purposes . The recording capability
of the electronic control modules is limited to
data only- no sound is recorded.
If the control
module detects a system ma lfunction or other
change in status, a very limited amount of da ­
ta is recorded for an extremely small period of
time . Data that is recorded in such a case may
include vehicle speed, d riving direction, the
load on the brakes and head restraints and
performance in the event of an acciden t or
other change in status . The stored data can
only be read or downloaded with special devi­
ces.
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) con­
tr ibutes to driver safety. It reduces the risk of
slipp ing and improves driving stability. ESC
Smart Technolog y 189
detects critical situations such as the vehicle
oversteering and understeering or the wheels
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torque.
Once the ESC is activated, the indicator light
m blinks in the instrument cluster .
The following systems are integrated in the
ESC:
Anti-lock braking system (ABS )
ABS prevents the whee ls from locking when
braking. The vehicle can still be steered even
during hard braking. Apply steady pressure to
the brake pedal. Do not pump the pedal. A
pulsing in the brake peda l indicates that the
system is acting to stabilize the vehicle.
Brake assi st sys tem
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sensit ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin spinning and adapts the force to
the road conditions . This makes it easier to
start , accelerate and dr ive up inclines .
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or wheels if the vehicle is equ ipped with
all wheel drive*). This function is not available
at higher speeds .
In extreme cases, EDL automatically switches
off to keep the brake on the braked wheel
from overheating . The vehicle is still working
correctly. EDL will switch on aga in automat i­
cally when cond itions have returned to nor-
mal. .,..
