Your vehicle is equipped with an electrome­
chanica l parking brake. The parking brake is
designed to prevent the vehicle from rolling
unintentionally and replaces the hand brake.
I n addition to the normal functions of a tradi­
tional hand brake , the electromechan ical
parking brake provides various convenience
and safety functions.
When starting from rest
-The integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢ page 78, Starting from rest .
- When starting on inclines, the starting as-
"' r-1 sist prevents the vehicle from unintentional-a::

Emergency brake function
An emergency brake ensures that the veh icle
can be slowed down even if the normal brakes
fail ¢ page 78, Emergency braking.
_& WARNING
Do not press the acce lerator pedal inadver­
tently if the vehicle is stationary but the
engine is running and a gear is selected.
Otherwise the vehicle will start to move immediately and could result in a crash.

vehicles or obstacles that are not moving
can trigger a collision warning and if con­
firmed by the v ideo camera, an acute col­
lis ion warn ing .
- For safety reasons, do not use adaptive
cruise co ntrol when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather
(such as ice, fog, gravel, heavy rain and
hydroplan ing) . Using the system under
these cond it ions cou ld result in a co lli ­
sion .
- Swi tch adap tive c ruise control off tempo­
rar ily when driv ing in turning lanes, on
expressway exits or in construction
zones. This prevents the vehicle from ac­
celerat ing to the set speed when in these
situations.
- The adapt ive cruise control system wi ll
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over­
ride the speed and distance regulation .
- When approaching stationary objects such as stopped traff ic, adaptive cruise
co ntrol will not respond and braking
guard w ill have limited function.
- The adapt ive cruise control system and
braking guard do not react to people, an­
imals, objects c rossing the road or on­
coming objects .
- The function of the radar senso rs can be
affected by reflective objects such as
guard rai ls , the entrance to a tunnel,
heavy rain or ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safe ly. The
adaptive cruise contro l canno t slow or
brake the vehicle safely when you follow
another vehicle too closely. Always re­
member that the automatic braking
function cannot br ing the vehicle to a
sudden or emergency stop under these condit ions.
- To prevent unintended operation, always switch ACC off when it is not being used. (D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That cou ld affect the adaptive
cruise control system and brak ing guard.

Audi active lane assist
Active lane assist
Description
App lies to vehicles: with active lane assist
Active lane assist helps you keep your vehicle
in your lane .
Active lane assist detects lane marker lines
within the limits of the system using a camera
in the windshield . If you are approaching a de­
tected lane marker line and it appears likely
that you w ill leave the lane, the system will
warn you by means of corrective steer ing . T he
d river can over ride the correct ive steer ing at
any time. If the veh icle crosses a line, the d riv­
er is also warned by a light
vibration in the
steering wheel. The vibration warning must be switched on in the MMI for this to happen.
Active lane ass ist is operable when the line
marking the lane is detected on at least one
side of the vehicle .
If the system is in active standby mode and
the turn signa l is activated before driving over
the lane marker line, the warning does not oc­
cur since the system allows for intentional lane changes.
The system is designed for driv ing on free ­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more .
If the vehicle is also equ ipped with Audi adap­
tive cruise control*, the corrective steering
will be more specific in regard to the driving
situation . In addition to the lane marker lines,
the system can also take into account other
objects such as guard rails . If they are detect­
ed i n close prox imity to the veh icle, Audi ac­
tive lane ass ist helps prevent the vehicle from
driving too close to them . There is also pass ­
ing assistance. The system does not provide
any corrective steering if it detects that you
are passing another vehicle.
A WARNING , ~
- The system warns the driver that the ve­
hicle is leaving the lane us ing corrective steer
ing. The driver is always responsible
for keeping the vehicle within the lane .
- The system can assist the driver in keep­
ing the vehicle in the lane, but it does
not steer by itself. Always keep your
hands on the steering wheel.
- Corrective steer ing may not occur in cer­
tain situat ions, such as dur ing heavy
brak ing .
- The camera does not recognize all lane
marker lines. Corrective steer ing can only
take p lace on the side of the vehicle
where lane marker lines are detected .
- Other road structures or objects cou ld
possibly be identified un intent ional ly as
lane marker lines . As a res ult, correct ive
steer ing may be unexpected or may not
occ ur.
- The camera view can be restricted, for
examp le by vehicles driving ahead o r by
r ai n, snow, heavy spray or light shining
into the camera. T his can result in act ive
lane assist not detecting the lane marker
lines or detect ing them incorrectly .
- Unde r ce rtain condi tions such as ruts in
the road, a banked roadway or cross­
winds, the co rrective steering alone may
not be eno ugh to keep the vehicle in the
lane.
- For safety reasons, active lane ass ist
must not be used when there are poor
road and/or weather conditions such as
slippery roads, fog, grave l, heavy rain,
snow and the potential for hydroplaning.
Using act ive lane assist under these con­
d itions may increase the risk of a crash.

• Not ready: The indicator light shows that
the system is turned on but unable to send a
warning. This can be due to the following:
- There is no lane marker line.
- The relevant lane marker lines are not de-
tected (for example, markings in a construc­
t ion zone or because they are obstructed by
snow, dirt, water or backlighting).
- The veh icle 's speed is below the speed need ­
ed to activate it , which is about 40 mph (65
km/h) .
- The lane is narrower than about 8
ft. (2 .5 m)
or wider than 15

94 Audi side assist
Side assist functions at speeds above approxi­
mately 19 mph (30 km/h).
(D Vehicles that are approaching
I n 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 or
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 or 15 km/h).
Functional limitations
The radar sensors are designed to detect the
left 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 senso rs
~ fig. 106 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will affect the funct ion . For
information on cleaning, refer to
~ page 201.
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 approaching or being left
behind very quickly. The disp lay may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow o r 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. .,..

96 Audi drive select
Audi drive select Driving settings
Introduction
Audi drive select makes it possible to experi­
ence different types of vehicle settings in one
vehicle. The driver can select three
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
example, you can combine settings such as a
sporty engine tuning with comfortable steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and seri­
ous personal injury.
Description
The following systems are affected by drive
select:
Engine and transmission
Depending on the mode, the engine and the
transmission respond quicker or in a more bal­
anced manner to accelerator 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 controlled air suspension and
damping system. They are adjusted depend­
ing on the selected driving mode, the driver's
steering, braking and acceleration input and
the road surface, 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 . The
highway 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 steering 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 steering .
The following applies to vehicles with dynamic
steering* : the steering ratio changes based on
vehicle speed in order to maintain optimum
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
maneuvering the vehicle. At low and average
speeds, dynamic steering additionally 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
driver, road surface, driving speed, and load.
This makes it possible to adapt damping to
the driving situation virtually in real time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortable suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all wheel drive system
(quattro)
c::;; page 193, the Sport differential*
distributes the driving power to the rear axle
depending on the situation. The distribution
of power varies depending on the selected
mode, from balanced (comfort) to agile (dy­
namic). The goal is a high level of agility and
