A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injury.
- Setting short distances to the traffic
ahead reduces the time and distance
available to br ing your vehicle to a safe
stop and ma kes it
even more necessary
to pay close attention to traffic.
- Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing distance for the traffic, road and
weather conditions .
¢j) Tips
- Distance 3
is set automatically each time
you switch the ignition on.
- Your standa rd settings are automatically
stored and assigned to the remote con­
trol key being used.

Fig . 11 3 Instrumen t cl uste r: approach warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise cont ro l is switched off .
What can Audi braking guard do? When detected i n time, the system ca n assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
hi gh speed and approachi ng a ve hicle up
a head that is moving more slowly . Brak ing
guard does not react if i t can not detect the
situation.
The system advises you of various situations :
- The distance warning is given if you are too
close to t he vehicle ahead for a long time . If
the vehicle ahead b rakes sharply, you w ill
not be ab le to avoid a c oll is io n. The indicator
li ght . i n the disp lay comes o n.
- The approach warning is given when a de ­
tected vehicle up ahead in your lane is mov­ i ng much more slowly tha n you are or if it
brakes sha rply . W hen th is w arning is given,
i t may only b e possib le to avoid a collision
b y swerving or braking s harply . Th e in dicator
l igh t. and indic ator in the di sp la y w ill
warn you about the danger

- If you do not re act to the acu te w arn ing,
bra king g uard can brake w it hi n the lim its of
the system . T his red uces the vehicle speed
in the event of a collision .
- At speeds un der 20 m ph (3 0 km/h), t he sys ­
tem can initiate a comp lete deceleration
short ly before a co llision

A WARNING
-Lack of attention can cause collisions, oth­
er accidents and serio us pe rsonal injuries.
The braking gua rd is an assist system and
ca nnot preve nt a collision by itself. The
dr ive r must alway s intervene. Th e dr ive r is

-Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
may prevent the proper detection of oth­
er vehicles.
- The radar sensor's function and range
can be reduced by rain, snow and heavy
spray. Moving vehicles up ahead may not be promptly detected or may not be de­
tected at al l.
- Reflective surfaces includ ing crash barr i­
ers or tunnel ent ran ces may impair the
function of the radar sensor.
- You can cance l the braking that is initiat­
ed by the system by braking yourself, by
accelerating noticeab ly or by swerving.

100 Audi side assist
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
@ Vehicles that are approaching
In certain cases, a vehicle will be classified as
cr itica l for a lane change even if it is still
somewhat far away . The faster a vehicle ap­
proaches, the sooner the display in the exteri ­
or mirror will turn on.
@ Vehicles traveling with you
Vehicles traveling with you are indicated in the
exterior m irror if they are classified as critica l
for a lane change. All vehicles detected by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
© Vehicles left behind
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph
(15 km/h)), the disp lay in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to de tect the
l eft and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the display in the exterior mirror may
turn on even though there is no vehicle locat­
ed in the area that is critical for a lane change.
For example:
- if the lanes are narrow or if your are driving
on the edge of your lane. If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane.
- if you are driving through a curve. Side assist
may react to a veh icle that is one lane over
from the adjacent lane.
- if side assist reacts to other objects (such as
high or displaced guard ra ils). -
In poor weather conditions . The side assist
functions are limited.
Do not cover the rada r sensors
~ fig. 117 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the function . For
information on cleaning, refer to ¢
page 184.
A WARNING
-
-Always pay attention to traffic and to the
area around your vehicle. Side assist can­
not replace a driver's attention. The driv­
er alone is always responsible for lane
changes and similar dr iving maneuvers .
- Improper reliance on the side assist sys­
tem can cause coll is ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain sit uations, the system may not
function or its function may be limited.
For example:
- if vehicles are approach ing or being left
behind ve ry quickly. The d isp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist.
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not
be detected because they are outside
of the sensor range .
([) Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
u nderbody. This can affect the system. .,..

Introduction
App lies to vehicles: with Audi drive select
Drive select provides the possib ility to exper i­
e nce diffe ren t types of vehi cle sett ings in o ne
ve hicl e. For ins tance, us ing t he three
Com­
fort , Auto and Dynamic modes, the driver can
switch from a sporty to a comfortab le drivi ng
mode with the press of a b utton.
A ddit ionally, in veh icles wi th MM I*, the vehi ­
cle setup for
Individual* mode can be c us­
tom ized by you . This makes it possib le to
comb ine settings such as a sporty engine tun ­
ing with comfortable steering.
A WARNING
Improper use of the A udi d rive select can
cause collisions , ot her acc idents and se ri­
ous pe rsonal injury .
Description
Applies to vehicles: with Audi drive select
The vehicle setup in each mode depends on
the veh icle's features . However, the engin e,
automa tic t ransmissio n and s teeri ng a re a l­
ways involved.
-
Engine and automatic transmission
Depending on the mode , the e ng ine and the
automatic t ransm ission respond quicke r or i n
a more ba la nced manne r to a cce le rator pedal
move ments. In t he sporty dynam ic mode, the
a ut om at ic t ra nsmissio n shifts at h igher R PMs.
The engine sound is ad justed by open ing or
clos ing t he exhaust doors for the respective
mode .
Steering
The stee ring ada pts in te rms of stee ring effort
an d steer ing ra tios. In direc t steer ing t hat
moves easi ly, like the stee ring in comfort
mode , is best su ite d to long dr ives on a high ­
way. In contrast, dynam ic mode p rov ides
sporty, d irect steering. T
he following app lies to veh icles with dynamic
stee ring *: the steering rat io chan ges base d on
vehicle speed in order to ma inta in optim um
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in o rder to provide improved vehicle
co ntrol. At r educed speeds, howeve r, s teer ing
is mo re d irect in o rder to k eep th e stee ring ef­
fo rt as minima l as poss ible whe n the drive r is
mane uveri ng the veh icle. At low and ave rage
s p eeds, dynamic steering ad dit iona lly pro ­
vides more responsive stee ring pe rformance .
Sport differential*
As a compone nt of the all whee l dr ive system
(qua ttro)
~ page 1 76 , the sp ort differential*
distributes the d riving power to the rear axle
depen ding on the si tuatio n. The dis trib ution
of power var ies depending on the mode se­
l ected . The goal is a high level of agility and
ability to accelerate on curves . The vehicle is
very respons ive to steering.
Audi adaptive cruise control*
T he be hav io r when accelera ting can be adjus t­
ed from comfortab le to sporty, de pendi ng on
t h e d rive select mode . Adaptive cru ise contro l
also responds to the driv ing behavior o f the
vehicle ahead in a more conservative or sporty man ner .
Engine sound*
The so und of the eng ine is adapte d to these ­
l ected mode and ranges from s ubt le to sporty .
(!) Tips
-In some mo dels, the maximum vehicle
spee d can only be reac hed in the
Auto
and Dynamic mo des .
- Selecting the
Dynamic mo de res ults in
sporty shifti ng cha racte ristics . T he 5
gear position engages aut omatically.
- In ve hicl es that have dynamic stee rin g* ,
operating noise is heard when start ing or
stopping the engine. This does not indi­
cate a problem.
