Audi adaptive cru ise control and brakin g guar d 101
Vehicles with manual transmission
App lies to vehicles: with Audi adaptive cruise control
The adaptive c ruise control is avai lab le from
the 2nd gear through the 6th gea r in the cus­
tomary RPM.
When the adapt ive cruise control is turned on,
you must p ress the clutch to shift gears (as
usual) . When sh ifting normally or when press­
ing the cl utch, the adap tive c ruise control re­
mains turned on.
Afte r you have engaged the gear, you do
not
need to press the gas peda l. The adaptive
cru ise control accelerates automat ica lly if nec­
essary.
I f you press dow n on the clutch fo r too long or
shift/coup le improperly, the adaptive cruise
control may turn off automat ically.
{D) Tips
You cannot tu rn on the adapt ive cru ise
contro l during a sh ifting operation.

Fig . 11 3 Detect ion range
What c an Audi adapt ive crui se cont rol d o?
The adaptive cruise control works in conjunc ­
tion with a radar sensor installed in the front
of the vehicle
¢page 99, fig. 110, which is
subject to desig nated system limits
<=:> page 101 . Stationary objects are disregard­
ed . On open
roads with no traffic, adaptive cr uise
control works like a regular cruise contro l sys­
tem. The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au­
tomat ica lly slows down to match that vehi ­
cle's speed and then maintains the distance
that the dr iver previously stored . As soon as
the sys tem does not detec t a vehicle up
ahead, adaptive cruise cont ro l ac celerates
back up to the stored speed .
Which functions can be controlled?
When you switch adapt ive cruise control on,
you can set the cu rrent speed as the "contro l
speed "
¢ page 102, Switching on and off.
When dr iving, you can stop cru ise contro l
¢page 103 or change the speed ¢page 103
at any time.
You can also set the distance to t he object
ahead and set the adapt ive cru ise control driv ­
ing program

whe n adapt ive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes s ud­
denly or if your own vehicle is t raveling at a
high speed and approac hing a ve hicle up
ahead that is movi ng mo re sl ow ly. B raking
guard does not reac t if it cannot detec t the
s ituation.
The system advis es yo u of various s ituations:
- The
distance wa rning is given if yo u are too
close to the vehicle ahead for a long time. If
the vehicle ahead bra kes sharply , yo u will
not be ab le to avoid a collision . The ind icator
light

- The
approach warning is given when a de­
tected ve hicle up ahead i n your lane is mov­
ing m uch mo re sl owly than you are or if i t

- If a co llision is imminent, the system will
first provide an
acute warning by bri efly and
sharp ly app ly ing the brakes .
- If you do not react to the ac ute warning ,
braking guard can brake within the limits of
the system. This reduces the veh icle speed
in the event of a collision.
- At speeds under 20 mph (30 km/h), the sys ­
tem can in it iate a complete deceleration
s hortly before a collision .
1>.
- If the braking guard senses that you are not
braking hard enough when a collision is im­
minent, it can increase the braking force.
Which funct ion s can be contr oll ed ?
You can switch braking guard and the dis­
tance/approach warning on or off in the radio
or MM I c> poge 106, Settings in the radio/
MMI.
A WARNING
Lack of attention can cause col lisions, oth­
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collis ion by itself. The
driver must always intervene . The driver is
always responsib le for bra king at the cor­
rect time.
- Always pay close attention to traffic,
even when the brak ing guard is switched
on. Be ready to intervene and be ready to
take complete control whenever necessa­
ry. A lways keep the safe and legal dis­
tance between your vehicle and vehicles
up ahead.
- Braking guard works w ith in limits and
will not respond outs ide the system lim­
its, for example when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or veh icle that has
broken down in traffic).
- Always remember that the radar sensor
for the braking guard works only within
defined detection and range limits that
l ) Th is is not available in some c oun tri es.
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 veh icles up ahead may not
be prompt ly detected or may not be de­
tected at all .
- Reflective surfaces including crash barri­
ers or tunne l entrances may impair the
function of the radar sensor .
(D Tips
- You can cancel the braking that is in it iat­
ed by the system by braking yourse lf, by
accelerating not iceably or by swerving .

Audi drive select Driving settings
Introduction
Appl ies to vehicles: wit h Audi drive select
Drive select provides the possibility to experi­
ence different types of vehicle settings in one
veh icle. For instance, using the three
Com­
fort, Auto and Dynamic modes, the driver can
switch from a sporty to a comfortab le driving
mode with the press of a button.
Addit ionally, in vehicles with
MM I*, the vehi ­
cle setup for
Individual* mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Applies to vehicles: w it h Audi drive select
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al­
ways involved.
-
Engine and automatic transmission*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to accelerator pedal
movements. In the sporty dynamic mode, the
automatic transmission shifts at higher RPMs .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steer ing that
moves easily, like the steering in comfort
mode, is best su ited to long dr ives on a high­
way. In contrast, dynamic mode prov ides
sporty, direct steering.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on
veh icle speed in order to maintain optimum
Audi drive select 113
steering effort for the driver at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steering
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record
information regarding steering movements,
braking and acceleration operations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually i n rea l time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortab le suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all wheel dr ive system
(quattro ®)
q poge 191, the sport differential*
distributes the driving power to the rear axle
depending on the situation . The distribution
of power varies depending on the mode se­ lected. The goal is a high level of agility and
ability to accelerate on curves . The vehicle is
very respons ive to steering .
Audi adaptive cru ise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cruise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound*
The sound of the engine is adapted to the se­
lected mode and ranges from subtle to sporty.

-In some models, the maximum vehicle
speed can only be reached in the
