ACC is active. Press the brake pedal to prevent
the vehicle from rolling or starting to move.
IIJ ACC : engin e speed
This message appears if the driver has not shifted
up or down in time when the adaptive cruise con­
trol is braking or accelerating, causing the vehicle
to exceed or to not reach the permitted eng ine
speed. The adapt ive cr uise control turns off. A
chime sounds as a reminder.
•••
Three wh ite dots appear if a setting cannot be se­
lected with the operat ing lever . For example, this
happens if adaptive cruise control cannot be act i­
vated when stopped because the dr iver has not
fastened the safety belt.
Doo r op en
Adaptive cruise control cannot be switched on
when the vehicle is stationary and the dr iver's
door is open.
Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense bas ic or Audi pre
sense front
W ith in the limits of the system, p re sense basic
and p re sense fro nt can initiate steps to protect
veh icle o ccupants i n certa in dangerous s itua­
tions.
Critical driving situat ions can be recognized by
the pre sense front v ia a network of differe nt ve ­
h icle systems and can take steps to prepare the
veh icle occ upan ts for a po ten tial coll is ion.
The pre sense front wo rks with a radar sensor and
a video camera*. It also functions within t he lim­
i ts of the system when adapt ive cr uise con trol* is
sw itched off.

Audi pre sense basic
Description
App lies to vehicles: wit h Aud i pre sense basic
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher .
The following functions can be triggered under certain conditions within the limits of the sys­
tem:
- Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt pretensioners. If a col lision
does not occur, the safety belts loosen slightly
and are ready to trigger again .
- Closing the windows and the sunroof* (for ex­
ample, when over- or understeering): the w in­
dows and the sunroof* close until there is only
a small gap open .
Audi drive select: the deployment time is adapt­ ed in dynam ic mode.
_&. WARNING ~
The pre sense basic cannot overcome natural
physical laws . It is a system des igned to assist
and it cannot p revent a coll ision. Do not let
the increased safety provided tempt you into
taking r is ks. Thi s co uld inc rease your risk of a
collis ion .
- The system can dep loy incorrectly due to
system-specific limits .
(D Tips
-Certa in p re sense bas ic functions switch off
when ESC is switched off (sport mode) o r
w hen driving in reverse. .,.

Ass is t
- The pre sense basic functions may not be
available if there is a malfunction in the ESC
system or the airbag control module.
- Note that with pre sense basic, the reversi·
ble safety belt pretensioner on the front
passenger's side deact ivates when the front
passenger's airbag is deactivated .
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi adaptive
cruise control
Pre sense front informs you if the d istance to the
vehicle ahead falls below the safe distance for a n
extended per iod of time.
It c an warn of a possi·
b le co llision and initiate braking maneuvers,
within the limits of the system.
When detected in time, the system can assess
dangerous situations whe re a n object ahead
b rakes s udden ly or if you r own vehicle is traveling
at a high speed and approaching an object t hat is
moving more s lowly . If detection is not possible ,
then pre sense front does not re act .

minent, it can increase the brak ing force .
A WARNING
-
-Pre sense front cannot overcome natura l
phys ica l laws. It is a system designed to as­
sist and it cannot prevent a collision. The
driver m ust always intervene . The d river is
always responsib le for brak ing at the correct
time . Do not let the in crea sed safety provid­
ed tempt you into ta king risks. This could in­

-Please note that the sensor does not always
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 ve­
hicle's path or are difficult to detect
¢ page 97.
-Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the funct ion of the radar sensor and
the system's ability to detect a collision risk .
- Lack of attention can lead to collisions, oth­
er 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 re­
sponsible for braking at the right time.
- Always pay attention to traffic, even when
pre sense front is switched on . Always be
ready to intervene and take over complete
control of the vehicle whenever it is neces­
sary. Always follow traffic laws regarding
maintaining a safe distance between your
vehicle and vehicles ahead.
- pre sense front works within certain limits
and cannot react to situations that are out­
side of the system limits, such as when ap­
proaching a stationary vehicle or a station­
ary obstacle (the end of a traffic jam or ave­
hicle that has broken down).
- Always keep in m ind that the radar sensor
for pre sense front only works w ith in de­
fined detection zones, which means other
vehicles may not always be detected correct­
ly.
- The function and range of the radar sensor
can be impaired by rain, snow and heavy
mist. Vehicles ahead may not be detected
right away, or not detected at a ll.
- Reflective surfaces such as guard rails or en­
trances to tunnels may impair the function
of the radar sensor.
(D Note
The sensor can be disp laced by impacts or
damage to the bumper, whee l hous ing and
underbody. The pre sense front sensor can be
damaged by this . Have an authorized Audi
Assist
dealer or authorized Audi Service Facility
check their function.
(D Tips
- You can cancel the braking with increasing
force that is initiated by the system by brak ­
ing yourself, by acce lerating noticeably or by
swerving .
- For information on driver messages about
pre sense, refer to ¢
page 106.
- Keep in mind that pre sense front can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
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 availa­
ble if there is a malfunction in the adaptive

Audi active lane assist
Description
Applies to vehicles : with Audi active lane assist
Active lane ass ist detects lane marker lines with­
in the limits of the system using a came ra in the
windshie ld. If you are app roach ing a detected
lane marker line and it appears like ly that you
will leave the lane, the system will warn you with
corrective steering . You can override this steering
at any time. If you pass over a line, the steering
wheel will v ibrate light ly. In order for this warn­
ing vibrat ion to occur, it must first be switched
on in the MMI. Active lane assist is operable
when the lane marker line is detected on at least one side of the veh icle.
l) T hi s function is not ava ilable in all cou ntri es.
106
The system will not warn you befo re crossing a
l ane marker line if you have activated the turn
s ignal. In this case, it assumes that you are
changing lanes intentionally.
The system is des igned for driving on express ­
ways and highways and therefore on ly activates
at speeds above approx imately 40 mph (65 km/
h).
A WARNING
-
- The system warns the driver that the vehicle
is leaving the lane using 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.
Al­
ways keep you r hands on the steering
wheel.
- Corrective steer ing may not occur in certa in
situa tions, su ch as during heavy braking.
- There may be cases where the camera does
not recognize all lane ma rker lines. Correc­
tive stee ring can only take p lace on the side
of the vehicle where lane marker line5 are
detec ted.
- Othe r road structures or obje cts cou ld possi­
b ly be identified un intent ionally as lane
marker l ines . As a result, corrective steering
may be unexpected or may not occur .
- The camera view can be restricted, for ex ­
ample by vehicles driving ahead or by rain,
snow, heavy spray light shining into the
camera or by d irt on the window. This can
result in active lane ass ist not detecting the
lane marker lines or detecting them incor­
rectly.
- In certain situat ions where visibility is low,
the vehicle may switch from "early" to "late"
corrective steering
l l.
- Under certain co nditions such as ruts in the
road, an inclined roadway or crosswinds, the
corrective steering a lone may not be enough
to keep the vehicle in the midd le of the lane.

Audi drive select (drive
settings)
Introduction
Applies to vehicles: with Audi drive select
Audi drive select makes it possible to experience
different types of vehicle settings in one vehicle.
The driver can select from three
Comfort, Auto
and Dynamic modes using the ~.7l.'i button in the
center console or the MMI to switch between a
sporty and a comfortable driving mode, for ex­
ample . In the
individual* mode, the settings can
be adjusted to your personal preferences . This
makes it possib le to combine settings such as a
sporty engine tun ing with light steering .
.,&. WARNING
Using Audi drive select incorrect ly can lead to
collisions, other accidents and serious inju ­
ries.
112
· Description
Applies to vehicles: with Audi drive se lect
The vehicle setup in each mode depends on the
vehicle's features. However , the eng ine and steer­
ing are always affected.
Engine and automatic transmission
Depending on the mode, the engine and auto­
matic transmission* respond more qu ickly or in a
more balanced manner to accelerator peda l
movements .
Adaptive dampers (Audi magnetic ride)*
The adaptive dampers use sensors to record in ­
format ion regarding steer ing movements, brak­
ing and acce lerat ion operations by the driver,
road surface, dr iv ing speed, and load. With Audi
drive select you can adjust the adaptive dampers
sporty (dynamic), comfortable (comfort) or bal­
anced (auto).
Steering
T he steer ing adapts in terms of steer ing ass is­
tance. There a re diffe rent modes
Q page 113.
Indirect steering that moves easily as in comfort
mode is especia lly suited to long drives on a high ­
way. The dynamic mode provides sporty, direct
steering .
For vehicles with progressive steering* the steer­
ing performance is more agi le .
Cornering light*
The cornering light adjusts when driv ing on
curves at speeds between 6 mph (10 km/h) and
68 mph (110 km/h). The pivoting action and the
lig hting are also adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
Audi drive select mode. Adaptive cruise control
also responds to the driving behavior of the vehi­
cle ahead in a more conservative or sporty man­
ner.

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. 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 pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. 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 whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped 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 over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

A WARNING
You should only switch sport mode on or switch ESC/ASR off if your driving ab ilities and
road condit ions perm it.
- The stabilization function is limited when
sport mode is switched on. The dr iving
wheels could sp in and the veh icle could
swerve, especially on slick or slippery road
surfaces.
- There is no vehicle stabilization when ESC/
ASR are switched off.
(D Tips
- ESC/ASR cannot be switched off or sport
mode cannot be sw itched on if the cru ise
control system* or the adapt ive cruise con­
trol* is switched on.
- Malfunctions in the Audi magnetic r ide may
make it impossible to sw itch the ESC/ASR
off or to switch spo rt mode o n.
Brakes
New brake pads
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" f irst. Howeve r, you can com­
pensate for the slightly reduced braking force by
press ing firmly on the b rake pedal. Avoid heavy
braking during the break -in period.
Wear
Brake pad wear is large ly dependent on the way
the veh icle is d riven and on operating co nditions.
This is especially t rue if you are driving frequent ly
in the city and on cu rves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, b rak ing force and o utside conditions s uch
as tempe rat ure and h umid ity.
Effect of water and road s alt
In certain situat ions, for example after driving
throug h wate r, in heavy ra in, after overn ight con­
densat ion or afte r wash ing you r car, the braking
In te llig ent T echnolog y
effect can be reduced by moisture or ice on the
brake rotors and brake pads . The brakes must be
"dried" first with a few careful brake applications.
At higher speeds and with the windsh ield wipers
turned on, the brake pads press against the b rake
rotors for a short amount of time . This action
wh ich is not felt by the driver happens at regular
intervals and facilitates a better reaction t ime for
the brakes in wet weather.
The braking effect can a lso be reduced if you are
driv ing on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first whe n the brakes a re applied .
Corro sio n
Leav ing the ve hicle parked for long periods of
t ime, low mileage and avoiding heavy braking can
contribute to corros ion on the brake rotors and
dirty brake pads.
If you usua lly avoid heavy b raking or if there is
corrosion present, occas ional heavy braking at
high speeds is recommended to clean the brake
rotors and pads¢,&.
Brake sy stem malfunct ion
if you notice that the b rake pedal travel has sud­
denly gotten larger, then a brake circ uit may have
failed. Drive to an authorized Audi dealer or au ­
thori zed Audi Service Facility immediately to have
the problem cor rected. On the way there, dr ive
with reduced speed and keep in mind that a long
braking distance and increased pressu re on the
brake pedal will be necessa ry.
Low br ake fluid level
When the brake f lu id level is low, malfunct ions in
the brake system may occur. The brake flu id leve l
is electronically mon itored.
Brake boo ste r
The brake booster amplifies the pressure yo u ap­
ply to the brake peda l.
It only works when the en-
gine is running.
