Audi adaptive cruise
control and braking
guard
Introduction
App lies to vehicles: with Audi adaptive cruise control
The adaptive cruise control system assists the
driver by regu lating vehicle speed and helping
to maintain a set distance to the vehicle
ahead, within the limits of the system . If the
system detects a moving vehicle up ahead,
adaptive cruise control can brake and then ac­
celerate your vehicle. This helps to make driv­
ing more comfortable both on long highway
stretches and in stop-and-go traffic.
The braking guard system can warn you about
an impending collision and initiate braking
maneuvers ¢
page 99.
Adaptive cruise control and braking guard
have technical limitations that you must
know, so please read this section carefully, un­
derstand how the system works and use them
properly at all times.

The areas that contain the radar and ultrason ­
ic sensors and the v ideo camera ¢
fig. 93
must neve r be covered by stickers or other ob­
jects or obstructed with dirt, insects, snow or
ice that will interfere with the adaptive cruise
control system and braking guard. For infor­
mation on cleaning, refer to ¢
page 218. The same applies for any modifications made in
the front area.
T he function of the adaptive cru ise contro l
system and braking guard is limited under
some conditions:
- Objects can on ly be detected when they are
w ith in sensor range
¢page 95, fig. 96 .
-The system has a limited ability to detect
objects that are a shor t distance ahead,
off
t o the side of your vehicle or moving into
your lane.
- Some kinds of ve hicles are hard to detect;
for examp le motorcycles, vehicles with high
ground clearance or overhanging loads may
be detected when it is too late or they may
not be detected at all.
- When driving through curves

& WARNING
Always pay attent ion to traffic when adap ­
tive cruise control is switched on and brak­ ing g uard is active. As the driver, you are
still respons ible for starting and for ma in­
taining speed and distance to other ob­
jects . Braking guard is used to assist you .
The driver must always take action to avo id
a collision. The driver is always responsible
for braking at the co rrect time.
- Improper use of adaptive cru ise control
can cause collisions, other acc idents and
serious pe rsonal in jury.
- Never let the comfort and conven ience
that adaptive cruise control and braking
guard offer d istract you from the need to
be alert to traffic condit ions and the
need to rema in in full control of your ve­
hicle at all times,
- Always remember that the adaptive
cruise control and braking guard have
limits -they will not s low the vehicle
down or maintain the set distance when
you drive towards an obstacle or some­
thing on or near the road that is not
mov ing, such as vehicles stopped in a
traffic jam, a stalled or disabled vehicle .

Audi drive select Driving settings
Introduction
Aud i drive select makes it possible to experi­
ence different types of vehicle settings in one
veh icle. The driver can select th ree
Comfort,
Auto
and Dynamic modes in the MMI to
switch between a sporty and a comfortable
driving mode.
You can also adjust the setting according to
your preferences in the
individual mode. For
examp le, you can combine settings such as a
sporty engine tuning with comfortab le steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury .
Description
The vehicle setup in each mode depends on
the vehicle's features. The engine, transm is­
sion, steering, reve rsible safety belt tension­
ers and adaptive air suspension are always in­
volved.
Engine and transmission
Depending on the mode, the engine and the
tra nsmission respond quicker or in a more bal­
anced manne r to acce lerator pedal move­
ments. In the sporty dynamic mode, the
transmission shifts at higher RPMs .
Air suspension
The adaptive air suspension/adaptive air sus­
pension sport*
( Air suspension in the MMI) is
an electronically con trolled air suspension and
damping sys tem. They are adjusted depend­
ing on the selected driving mode, the drive r's
steering, braking and acceleration input and
the road s urface, vehicle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport*.

The vehicle clearance varies depending on the
selected mode and the speed .
T he hig hway setting is activated automatically
when you drive above 75 mph (120 km/h) for
more than 30 seconds in the
auto or dynamic
mode. The ground clearance is increased auto­
matically if the speed drops below 44 mph
(70 km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect stee ring that
moves easily, like the steering in comfort
mode, is best suited to long drives on a high­
way . In contrast, dynamic mode provides
sporty, direct steer ing .
The following applies to vehicles with dynamic steering* : the steering ratio changes based on
vehicle speed in order to ma inta in optimum
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is mo re direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuvering the vehicle. At low and average
speeds, dynamic steering additiona lly pro­
vides more responsive steering performance.
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
<:!) page 203, the Sport differen­
tia l* distributes the driving power to the rear
axle depending on the situation . The distribu ­
tion of power varies depending on the select ­
ed mode, from balanced (comfort) to agile
(dynamic). The goal is a high level of agility
and ability to accelerate on curves . The vehicle
is very responsive to steering.
Curve light*
The curve light adapts to driving on curves.
The pivoting act ion and the lighting are also
adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on .,..
