Ass is tan ce sys tems
speed and the distance between your
vehicle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road condit ions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because th is increases the
r isk of an accident.
- Switch the cruise control off temporar ily
when driving in turn ing lanes, h ighway exits
or in construction zones.
- Please note that unconsciously "resting" yo ur foot on the accelerator pedal prevents
the cruise control from braking. This is be­
ca use p ressing the acce le rato r pedal ove r­
rides the c ruise contro l system.
- If a bra ke system ma lf u nction such as over­
heating occu rs when the c ruise contro l sys­
tem is sw itched on, the braking function in
the system may be switched off . The rest of
the cr uise control system f unctions remain
active as long as the
(lj;(i)~i~ (USA models) /
Bl (Canada models) indicator light is on.
(D Note
Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. Th is makes use of the eng ine
braking effect and relieves the brakes.
@ Tips
The brake lights turn on when the brakes a re
activated.
Changing the speed

Audi pre sense
Introduction
Appl ies to : vehicles wit h Aud i pre sense
Within t he limits of the system, the pre sense
f unct ions can initiate measures in pa rtic ularly
dange rous situations to protect the vehicle pas-
sengers and other road users.
..,.
133

Assistance systems
-Due to the interlinking of various vehicle sys­
tems, critica l driving situations can be detected
by
pre sense basic and measures for preventa­
tive occupant protection are can be initiated.
-The pre sense front uses the data from the ra­
dar sensors and calcu lates the probability of an
accident
c> page 127. An impending collision
with vehicles can be detected within the limits
of the system . In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can i ni­
tiate a partia l or full dece le rat ion to reduce the
collision speed o r to avoid the coll ision unde r
ce rtain c ircumstances. In conjunction with pre
sense basic, the front safety belts are also re­
versib ly tensioned when needed . The pre sense
front is also active when adaptive cruise con­
trol* is sw itched off.
.,&. WARNING
Also follow the general instructions found in
c> .&. in General information on page 127.
(i) Tips
-Certain pre sense functions switch off when
driving in reverse.
-The pre sense functions may not be availa­ ble if there is a malfunction in the ESC sys­
tem or the airbag contro l module.
-Note that the reversible belt tensioner on
the front passenger's side deactivates when
the front passenger's a irbag is deactivated .
-Switch the pre sense off when you are not
us ing public streets or when loading the ve­
hicle onto a vehicle carr ier, train, ship or
other type of transportation. This can pre­
vent an undes ired intervention from the pre
sense system.
Audi pre sense basic
Description
Applies to: veh icles with Audi pre sense basic
The pre sense basic funct ions are activated at a
speed of approximately 20 mph (30 km/h) or h igher.
134 The following
functions can be triggered under
certain conditions within the limits of the sys ­
tem:
-Tensioning of the safety bel ts (for examp le,
during heavy braking): the front safety belts
have reversib le be lt tensioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger aga in.
-Initiating the closing of the windows and the
panorama glass roof* (for examp le when un­
der- or oversteering).
Audi drive select* : the trigger times are adjusted
depending on the mode selected.
Audi pre sense front
· Description
Applies to: vehicles with Audi pre sense front
Within the limits of the system and depending
on the situation and speed, pre sense front can
warn you about impending collisions with sta­
tionary, stopped, and moving vehicles and ini ­
tiate appropriate braking measures.
If detection is not possib le, then pre sense front
does not react.
The following func tions trigger in conjunction
with pre sense basic at corresponding vehicle
speeds :
-Reversible tens ion ing of the front safety belts.
-Closing the windows and panorama glass roof*.

Intelligent Technology Electronic Stabilization
Control (ESC)
Description
Electronic Stabilization Control ( ESC) supports
driver safety . It reduces the risk of slipping and
improves dr iving stability. ESC detects critica l sit­
uations such as the vehicle oversteering and un­
dersteer ing or the wheels are spinning. The vehi­
cle is stabilized by apply ing the brakes or reduc ­
ing engine torque . When the ESC engages, the
G1 indicato r light b links in the instrume nt clus­
ter.
The follow ing systems are integrated in the ESC:
Anti-loc k bra king system (ABS)
ABS prevents the whee ls from locking when brak­
ing. The vehicle can still be steered even during
hard brak ing. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
b rake pedal indicates that the system is act ing to
stabilize the vehicle .
Brake a ssist system
The brake assist system can decrease braking dis­
tance. It increases brak ing power when the driver
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold the brake pedal
u nti l the dangerous sit uat io n is ove r. In veh icles
with adaptive cr uise contro l*, the bra ke assist
s ys tem is more sensitive if t he d istance detec ted
to the veh icle dr iv ing ahe ad is too small.
Anti -slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
begin spinning and adapts the force to the road
conditions . This makes i t eas ie r to sta rt, acceler­
ate and dr ive up hill s.
Electronic differential lock (EDL )
The EDL applies the brakes to a wheel that starts
spinning and transfers t he drive power to the
other driving wheel or wheels ( if the veh icle is
eq uipped w ith all whee l dr ive*) . T his function is
n o t available at higher speeds.
Intellig ent Technology
In extreme cases, ED L automat ica lly switches off
to keep the brake o n the braked whee l from over­
heating. The veh icle is still working correct ly. EDL
will switch on again automatically when condi­
t ions have returned to normal.
Ste ering recommendation
The ESC he lps to s tabilize the vehicle by changing
the steering torque.
Select ive wheel torque control
Se lective wheel to rque cont rol is used w hen driv­
i ng on curves. The fron t whee l on the inside of
the curve or bo th wheels on the i nside of the
c u rve are braked se lective ly as needed . This al­
l ows more precise driving in c urves.
Automatic post-collision braking system
T he "automat ic pos t-collision braking system"
c an help to reduce the risk of sliding an d of addi ­
tiona l co llisions a fter an acciden t. If the ai rbag
contro l modu le detects a co llision above a certain
vehicle speed, the veh icle is bra ked by the ESC.
T he vehicle does not bra ke autorn,;1tically if;
- t he dr ive r presses the acce le rator pedal, or
- the ESC, the brake system or the veh icle elect ri-
cal system are not functioning .
A WARNING
-The ESC and its integ rated systems cannot
overcome the lim its imposed by natura l
phys ic al laws. This is especially important
on sli ppery or wet roads . If the sy stems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the inc reased safety provided tempt
you into taking risks. This could increase
your r isk of a coll is ion.
- Please n ote the r isk of a coll is ion increases
when dr iv ing fast, especially t hrough curves
a nd on slippery or wet roads, and when dr iv­
ing too close to objects ahead. The ESC and
its integrated systems ca nnot always pre­
vent collisions
-there is st ill a ris k of ac ci-
dents!
