Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
certain 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). The
deployment time is adapted in the drive select
mode dynamic.
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 collis io n the following functions can be
triggered:
- Braking guard
~page 98
-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 coll ision with the veh icle
coming from behind is also calculated. If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening 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 optimized for the front seats and
the outboa rd 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 rea r.
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
vehicle's path~
page 92.
-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 being ac­
curately detected and in some cases they
may not be detected at all.
Ill>

198 Intelligent technology
vehicles with adaptive cruise control*, the brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti-slip regulati on (ASR )
ASR reduces engine power when the d rive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other d rive
wheel or whee ls if the vehicle is equipped with
all whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases, ED L automatica lly switches
off to help keep the brake on the braked whee l
from overheating . EDL wi ll switch on again au­
tomatically when conditions have returned to normal.
Dynamic steer ing*
On vehicles with dynamic steering, ESC he lps
stabilize the steering in certain situations .
Selective wheel torque control
The se lective wheel torque cont ro l operates
when dr iving thro ugh cu rves. The front wheel
on the ins ide of the curve or both w heels on
the inside of the curve are braked selective ly
as needed. This minimizes sliding in the front
wheels and a llows for more precise driving
through curves. The applicab le system may
not activate when driving in wet or snowy con­
d itions .
Post- coll isio n br ake assis t
"Post-collision brake assist" can assist the
driver during a collision by reducing the dan­
ger of slipp ing and further collision and by au­
tomatic braking.
"Post-collision brake assist" functions d uring
collisions when the a irbag contro l modu le de­
tects a trigger level and the collision takes place at a certa in driving speed. The brak ing
of the vehicle happens automatically via the ESC as
long as the ESC, the brake system, and
the vehicle electrical system are not damaged
from the collision.
T he following ac tivit ies override the au toma t­
ic braking during a co llision:
- I f the driver p resses the acce le rator pedal.
There is no automa tic brak ing .
- When the force on the press brake peda l is
st ronger tha n the braking force initiated by
t he system. The veh icle is manua lly braked.
- When the ESC is damaged, the "Post-colli­
sion brake assist" is not available.
,&. WARNING
- ESC, ABS, ASR, ED L, dynamic steeri ng *
and the select ive wheel torque control
cannot overcome the laws of physics .
This is especially important on s lippery
or wet roads. If the systems beg in acting
to stabilize your veh icle, you should im­
mediately change your speed to match
the road and traffic conditions. Do not let the increased safety provided by
these systems tempt you to take r is ks.
D oing so will increase the risk of a loss of
veh icle contro l, col lision and ser ious per ­
sonal injuries.
- Always ad apt your speed to road, traffi c
and weather conditions . The risk of los ­
ing contro l of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, EDL, ASR, dynam ic steering* and
the selective wheel torque cont ro l can­
not prevent collisions.
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with i ce and snow.
The drive wheels can spin even w ith
these assistance systems tha t cannot al­
ways he lp to red uce the risk of loss of ve -
