Audi pre sense Preventative passenger
protection
App lies to veh icles: with Audi p re se nse
Audi pre sen se can ini tiate steps to help pro­
t ect vehicle occupants in certain situations.
The funct ions descr ibed depend on equipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
cert ain driving situations :
- Tightening 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 be tightened again .
- Closing the windows and the sunroof* : the
windows and the sunroof" close leaving a
small open gap .
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h) .
Vehicles with Audi drive select*: the deploy­
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered:
- Braking guard
¢ page 100
-Tightening the safety belts
- Closing the windows and the sunroof* ( leav-
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end col lision with the vehicle
coming from behind is also calculated. If the
Audi pre sense 197
risk of a collision is detected, the following
functions can be triggered :
- Tightening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats: the settings for the
power head restrains, the upper sections of
the backrests and the pneumatic side bol­
sters* are optim ized for the front seats and
the outboard rear seats*. If a collision does
not occur, the previous seat settings are re­
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk of a collision and serious personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli­
sion.
-Audi pre sense does not detect people or
animals or objects that are crossing the
veh icle's path ¢
page 94.
- The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from be ing ac­
curately detected and in some cases they
may not be detected at all.

200 Intellig ent technol ogy
ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-slip regulat ion (ASR), electronic
d ifferential lock (EDL), dynamic steering* and
electronic interaxle differential lock*. ESC is
switched on all the time. In certain situations
when you need less tract ion, you ca n sw itch
off ASR by pressing the button above
~ page 201, fig. 188 the se lector lever. Be
sure to sw itch ASR on aga in when you no lon­
ger need less traction.
Anti -lock braking system (ABS )
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered
even du ring ha rd b raking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
a l. A pulsing in the brake peda l indicates that
the system is he lping you to brake the vehicle.
Br ake assist system
The brake assist system can decrease brak ing
d istance. It increases braking power when the
d river p resses the brake pedal q uick ly in emer­
gency situations. You must press and hold the brake peda l until the situation is over. In
vehicles with adaptive cruise control*, the brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti- slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
El ectronic diff erential lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all whee l drive*. This funct ion is available up
to about 7S mph (120 km/h).
In extreme cases, EDL a utomatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL will switch on again au­
tomatically when conditions have returned to normal.
Dynamic ste ering *
On vehicles with dynamic s teering, ES C helps
stabilize the steering in certain situations.
Electronic interaxle differential lock
function*
T he electronic interaxle differentia l lock f unc­
tion activates when driving thro ugh curves.
Braking is targeted toward the wheels on the
inside of the curve as needed . This he lps to
minimize front whee l skid, improves traction
and allows for more precise driving through
curves .
A WARNING
- ESC, ABS, ASR, EDL, dynamic steering*
and the electronic interaxle differential loc k function* cannot overcome the laws
of physics. This is espec ially impo rtant
on slippery o r we t roads.
If the systems
begin acting to stabilize your vehicle, you
should immediately change yo ur speed
to match the road and traffic conditions .
Do not let the increased safety provided
by these systems tempt you to take risks. Doing so will increase the risk of a loss of
veh icle control, collision and ser ious per­
sonal injur ies.
-Always adapt your speed to road, traffic and weather conditions. The risk of los­ing control of the vehicle increases when
d riving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys ­
tem, EDL, ASR, dynamic steering * and
the electron ic interaxle differential lock
function* cannot prevent collisions.
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
h icle control.
