Warnings
App lies to vehicles: with Audi pre sense front or Audi
adaptive cruise control
Fig. 94 Instrument cluster: approac h warning
The system recognizes various dangerous sit­
uations:
- Vehicles with adaptive cruise control : The
distance warning occurs if you drive too
closely to the object ahead for a long period
of t ime. If the object ahead brakes strongly,
you would not be able to avoid a coll ision.
The indicator light . indicates this.
- The
approach warning occurs when an ob­
ject ahead is traveling mo re slowly or brakes
strongly. When this warning occurs, it may only be possible to avoid a collision by
swerving or braking strongly. The message
Audi pre sense. Distance ¢ fig . 94 and a
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 situation that was detected by the
system, pre sense front provides ass istance 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

control, the. indicator light also turns on.
- If you do not react to the acute warning, pre
sense front can brake with increasing force

lision. The message Audi pre sense -Input
also appears.
- At low driving speeds , pre sense front can
begin complete deceleration shortly before
a collision
ll .
- If pre sense front determines that you are
not braking strongly enough when a colli ­
sion is immin ent, it can increas e 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 time. 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 ¢
page 87, 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
complete control of the vehicle whenever

it is necessary. Always follow traffic laws
regarding mainta ining a safe distance
between your vehicle and veh icles 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 in m ind that the radar sen ­
sor for pre sense front only works within defined detection zones, which means
other vehicles may not alw ays be detect­
ed correct ly.
- T he function and range of the radar sen­
sor c an be impaired by rain, snow and
heavy mist. Vehicles ahead may not be
detected right away, o r not detected at
all .
- Reflective surfaces such as guard rails or
entrances to t unnels 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 housing and
underbody . The pre sense front sensor can
be damaged by this . Have an authorized
Aud i dea ler or a uthori zed Audi Service Fa­
cility check their function.
(D} Tips
- You can cance l the braking with increas­
ing fo rce that is initiated by the system
by braking yo urself, by accelerating no­
ticeab ly or by swerving.
- For information on dr iver messages
about pre sense, refer to<=> page 97.
- Keep in mind that pre sense front can brake unexpectedly . Always secure any
cargo or objects that you are transport­
i ng to reduce the risk of damage o r in­
Jury .
- Certain pre sense front funct ions switch
off when ESC is sw itched off (sport
mode) or when driving in reverse .

Audi drive select Driving settings
Introduction
Applies to vehicles: with Audi drive select
Audi drive select makes it possible to experi­
ence diffe rent types of vehicle settings in one
vehicle. The driver can select from three
com­
fort , auto
and dynamic modes using the 1:1:.~
button in the center conso le or the MM I to
switch between a sporty and a comfortable
driving mode, for examp le. In the
individual *
mode, the settings can be adjusted to your
personal preferences. This makes it poss ible
to combine settings such as a sporty eng ine
tuning with light steering.
A WARNING
Using Audi drive select incorrectly can lead
to collisions, other accidents and serious injuries.
Description
Applies to vehicles: with Audi drive select
The vehicle setup in each mode depends on
the vehicle's features. However, the engine
and steering are always affected .
Engine and automatic transmission
Depending on the mode, the engine and auto­
mat ic transmission* respond more quickly or
in a more balanced manner to acce lerator
pedal movements.
Adaptive dampers (Audi magnetic ride)*
The adaptive dampers use senso rs to record
information regarding steering movements,
brak ing and acce lerat ion operat ions by the
driver, road surface, driving speed, and load.
With Audi drive se lect you can adjust the
adaptive dampers sporty (dynamic), comfort­
ab le (comfort) or balanced (auto).
Steering
The stee ring adapts in terms of stee ring assis­
tance. There are different modes
¢page 108.
Indirect steering that moves easi ly as in com -
Audi drive select 107
fort mode is especially suited to long drives
on a highway. The dynamic mode provides
sporty, direct steer ing.
For vehicles wi th progressive steering* the
steering performance is mo re agile.
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 lighting are also adapted to the
mode.
Adaptive cruise control*
T he behav ior when accelerating can be adjust­
ed from comfortable to sporty, depending on
the Aud i drive select mode. Adapt ive cru ise
control also responds to the driving behavior
of the vehicle ahead in a more conservative or
sporty manner.
(D Tips
In some mode ls, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.

- If the engine must run while you are
working in the eng ine compartment with
the hood open, make sure a gear is not
engaged. The selector lever must be
firmly in the
P pos it ion and locked in
place and the pa rking brake must be set

@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
i s selected. This can cause the automatic
transmission to overheat and can dam­
age it. Set the park ing brake or press the
brake pedal to prevent t he veh icle from

(D Tips
For safety reasons, the park ing brake re­
leases automatically only when the driver's
door is closed and dr iver's safety be lt is
fastened.
Hill descent control
Applies to veh icles: w ith S tronic transm iss io n
Hill descent control assists the driver when
driving down hills .
Hill descent contro l is activated when these­
lector lever is in the Dor 5 position and you
press the brake pedal. The transm ission auto­
matically selects a gear that is su itab le for the
incl ine. Hill descent cont ro l tries to ma inta in
t h e speed ac hieved at the t ime of b raking,
within physica l and tec hni cal limitations. If
may sti ll be necessary to ad just the speed
with the brakes . Because hill descent control
cannot shift down farther than 3rd gea r, it
may be necessary to sh ift into t iptronic mode
i n very steep areas . In this case, shift into 1st
or 2nd gear in t iptron ic mode to use the en­
gine's brak ing force to relieve the brakes .
Hill descent contro l sw itches off once the h ill
levels out or you press the accelerator pedal.
On vehicles with a cruise contro l system*
¢ page 85, hill descent control is also activat ­
ed when the speed is set.
A WARNING
--
H ill descent control cannot overcome
physical lim itations, so it may not be ab le
to maintain a constant speed unde r a ll
conditions. A lways be ready to apply the
b rakes.

Information about
data recorded by
vehicle control
modules
Your vehicle is not equipped with a crash data
recorder. This device is insta lled by some vehi­
cle manufacturers to record data about crash ­
es so tha t 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 veh icle is not equipped with a crash data
recorder. However it does contain a var iety of
e lectronic control modules for various vehicle
systems such as eng ine funct ion, exhaust
treatment or airbags and safety belts .
These electron ic control modules record vehi­
cle data during normal driv ing for diagnosis
and repair purposes. The recording capab ility
of the electron ic control modules is lim ited to
data only- no sound is reco rded.
If t he control
mo dule detects a sys tem m alfu nction or other
change in sta tus, a very lim ited amount of da­
ta is recorded for an extreme ly sma ll period of
time . Data t hat is recorded in s uch a case may
include veh icle speed, driving direction, the
load on the brakes and head restraints and
performance in the event of an acc iden t or
other change in status . The stored data can
only be read o r down loaded w ith specia l dev i­
ces.
Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Cont rol (ESC) con­
tr ibutes to d river safety. It reduces the risk of
slipp ing and improves driving stability. ESC detects critical situations such as the veh
icle
oversteering and understeering or the whee ls
are spinning . The vehicle is stabilized by ap­
plying the brakes or reducing engine torq ue.
Once the ESC is activated, the ind icator light
Bl blinks in the instrument cluster .
The following systems are integrated in the ESC:
Anti -lock braking s ystem (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle can still be steered even
during hard braking . App ly steady pressure to
the brake peda l. Do not pump the peda l. A
puls ing in the brake peda l ind icates that the
system is act ing to stabilize the ve hicle.
Brake assi st sy st e m
The brake assist system can decrease braking
distance .
It increases braking power when the
driver presses the brake peda l quickly in emer­
gency s ituations. You m ust press and hold the
brake pedal until the dangerous situation is
over . In vehicles with adaptive cruise control*,
the brake assist system is more sens it ive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regu lation (ASR )
ASR reduces engine power when the drive
wheels begin sp inning and adapts the force to
the road conditions. This makes it easier to
sta rt , accelerate and dr ive up inclines .
Electronic differenti al lock (EDL )
The EDL brakes whee ls 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 ava ilable
at h igher speeds .
In extreme cases, EDL automatically sw itches
off to keep t he b rake on the braked wheel
from overheat ing. The ve hicle is still working
co rrect ly. EDL w ill switch o n aga in automat i­
ca lly when cond itions have ret urned to no r-
mal. .,._

Attempting to wo rk on electronic components
and the softwa re used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved . Th is means that you risk both
a substantial reduction in the operat ional
safety of you r vehicle and an increased wear of
ve hicle parts

A WARNING
Imprope r repairs and modifications can
change the way vehicle systems work and
cause damage to the veh icle and serious
personal injury.
