Adaptive cruise control
The adaptive cruise control system only reacts to
vehicles which are moving or which have already
been detected as moving vehicles. For example,
if
a
vehicle ©, which has already been detected
by the adaptive cruise control, turns off or
changes lane and another stationary vehicle © is
located in front of that
vehicLe,
the system will
not react to the stationary vehicle. Press the
brake pedal to slow down.
Vehicles with manual gearbox
Applies to: vehicles with Audi adaptive cruise control and
manual gearbox
The adaptive cruise control is available in second
gear or higher (when driven in the normal engine
speed range).
When the adaptive cruise control is switched on,
you must press the clutch pedal in the normal
way in order to change gear. The adaptive cruise
control will remain activated when you change
gear or press the clutch pedal.
You do not need to press the accelerator after se­
lecting a gear and releasing the clutch. The adap-

tive cruise control system accelerates the vehicle
automatically as appropriate.
The adaptive cruise control may be switched off
automatically if
you
keep the clutch pedal de­
pressed for too long or if
you
change gears incor­
rectly or use the clutch pedal improperly.

can help to keep the vehicle in Lane. The system
steers the vehicle automatically when the adap­
tive cruise control is switched on (subject to cer­
tain inherent system limitations). As the name
implies, the purpose of the traffic jam assist
function is to assist the driver; the driver must
keep his/her hands on the steering wheel at all
times and must always be ready to take over the

steering.
The driver can override the automatic
steering at any time by steering manually.
The system is designed for driving on motorways
and major roads.

Audi pre sense front
Description
Applies to: vehicles with Audi pre sense front
In certain situations and at certain speeds, pre
sense front can warn you if there is a danger of
collision with crossing
pedestrians1^
or station­
ary, parked and moving vehicles, and can apply
the brakes if necessary.
Pre sense front will not react if it is not in a
posi­

tion to detect the danger.
In conjunction with pre sense basic, the following
functions may be initiated, depending on how
fast the vehicle is travelling:
- Activation of reversible front seat belt tension­

ers.

-Automatic closing of windows and panorama

Fig.
113 Instrument cluster: Collision warning
Advance warning/acute warning
The system can give visual and audible warnings
if it detects a dangerous situation. An advance
warning can be given if:
- A vehicle in front brakes suddenly.
- Your own vehicle approaches a stationary
vehi­

cle at
a
speed of approx. 30 to 85 km/h.
- Your own vehicLe approaches a much slower ve­
hicle travelling in the same direction or
a
sta­
tionary vehicle ahead at
a
speed of more than
approx. 30 km/h.

x)
Not available on vehicles for some markets.
- A crossing
pedestrian15
moves into your lane
and you are travelling at a speed of approx. 30
to 65 km/h.
If this warning is given, you may need to take
evasive action or brake hard to avoid a collision.
The driver message Audi pre sense
| Sj
^>Fig.
113
and a warning tone draw your attention to the
danger.
In the event of an impending collision with a ve­

hicle,
an acute warning is also given in the form
of
a
brake jolt. If
you
do not respond to the acute

warning,
pre sense front
can,
subject to general
system limitations, apply the brakes with in­
creasing brake force, in order to slow the vehicle
down and take the impact out of
a
potential
colli­

sion.

Automatic braking
Pre sense front can initiate an automatic brake
application at certain speeds just before a
colli­

sion:

- At up to 85 km/h if vehicles are stopped.
- At any speed if moving or stopping vehicles are
detected ahead.
- At up to approx. 65 km/h if pedestrians are

crossing15.

Automatic brake pressure increase
If pre sense front detects
that
you are not brak­
ing hard enough in the event of an impending

collision,
it will increase the brake pressure, de­
pending on the situation and speed:
- At up to 85 km/h if vehicles are stopped.
- At any speed if moving or stopping vehicles are
detected ahead.
WARNING
The protection provided by pre sense front is
still subject to the prevailing physical limits.
It is a driver assist function and cannot pre­
vent
a
collision in every situation. The driver
must always intervene personally. As the driv­
er you are always responsible for braking in
good time. Do not let the extra safety
121

Driver assist systems
provided tempt you into taking any risks when
driving - this can cause accidents.
- Please note that pre sense front can give
warnings or apply the brakes unexpectedly.
Always secure your luggage to prevent dam­
age and possible injury.
- Due to inherent system limitations, false ac­
tivation of the system is possible.
- Please note that the sensor is not always
able to detect all objects which may repre­
sent a potential hazard - risk of accident!
- Pre sense front does not react to the follow­

ing:
oncoming traffic in the same lane, sta­
tionary or stopped persons, pedestrians
crossing the road at an angle, groups of
people, animals, or objects that are hard to

recognise •=>
A in General notes on
page 112.
A WARNING
The pre sense front functions may be restric­
ted or unavailable in situations such as the

following:

- If objects such as crash barriers or other
vehicles are reflecting additional light.
- At tunnel entrances.
- In heavy fog,
rain,
road spray or snow.
- If the radar sensor is dirty, frosted, dam­
aged or covered.
- When driving through a corner.
-Applies to: front-wheel drive vehicles: If the
ESC system has been partially or fully deac­

tivated.

© CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensor. This can impair the function of
the pre sense front system. Have the systems
checked by a
quaLified
workshop.
© Note
-The automatic brake application with in­
creasing brake force can be cancelled by ap­
plying the brakes yourself or by pressing the
accelerator firmly or by taking evasive ac­

tion.

- Applies to: front-wheel drive vehicles: Cer­
tain pre sense front functions are deactiva­
ted when the ESC

Audi active Lane assist
Description
Applies to: vehicles with Audi active lane assist
The active lane assist (lane departure warning
feature) uses a camera in the windscreen to de­
tect lane markings (subject to general system
limitations). If
you
approach one of the detected
lane markings, the system corrects the steering
to warn you that the vehicle might be about to
cross one of the markings. You can override this
steering input at any time. The steering wheel vi­
brates slightly if
you
cross a lane marking. The vi­
bration warning must be activated beforehand on
the infotainment system. The active lane assist is
functional when it detects a demarcation line on
at least one side of the lane in which you are driv­

ing.

As the system is designed for driving on motor­
ways and other major roads, it is only active

§
above a speed of about 65 km/h (may vary in dif-

£
ferent export markets).
r\i

.-H

00
A WARNING
- The system initiates a corrective steering in­
put to warn the driver that the vehicle is
about to leave the lane. As the driver you
are always responsible for staying in your
own lane.
- The system can assist you to keep the
vehi­

cle in the lane, however it is not capable of
driving on its own. Never take your hands
off the steering wheel.
- In certain situations, e.g. during heavy brak­

ing,
the system may not correct the steer­

ing.

- In certain circumstances, not all of the lane
markings may be detected by the camera. A
corrective steering input can only be
initi­

ated if the system detects a lane marking on
the side in question.
- Variations in the road surface or objects on
the road may be misinterpreted as lane
markings. In this case, the steering may be
corrected unexpectedly or not at all.
- The camera's view might be obstructed, for
example by vehicles travelling in front,
rain,

snow, a lot of water on the
road,
adverse
light
or
dirt on the windscreen. If this hap­

pens,
the active lane assist may not detect

Driver assist systems
the lane markings or may respond incorrect-

iy.

- In certain circumstances, for instance if
visi­

bility is poor, the setting for the steering in­
put may temporarily be switched from "ear­

ly"
to "late"
«.

- In certain driving conditions, such as ruts in
the road surface, adverse cambers or side
winds, the assistance provided by the steer­
ing correction may be insufficient to keep
the vehicle in the middle of the lane.
- For safety reasons, the active lane assist
must not be used in poor weather or in
diffi­

cult or slippery road conditions (such as ice,

fog,
loose grit or gravel, heavy
rain,
snow,
etc.) - risk of accident!

Emergency assist
Applies to: vehicles with emergency assist
The emergency assist takes over controL of the
vehicle in certain situations and can help to pre­
vent accidents. It is an extension of the active
lane assist and can use the functions of the adap­
tive cruise control system
<=>^.
The emergency
assist is activated when it detects that the driver
has stopped steering the vehicle.
Functions of the emergency assist
The emergency assist monitors the steering ac­
tivity of the driver. It detects if the driver is inac­
tive and gives repeated visual and audible warn­
ings as well as brake jolts prompting the driver to
take proactive control of the vehicle again. The
hazard warning lights are also switched on when
the first sharp brake jolt is given below
a
speed of
80
km/h15.

If the driver does not take over, the system inter­
venes by steering the vehicle (within the limita­
tions of the system) to keep it in lane, and by ap­
plying the brakes until the vehicle has stopped*.
In addition, the warning lamp || and a message
